We're sure there are tons of them. When you find them, send them to us and
we'll fix them ASAP. We'd love to have a bugless bot someday...
Incidentally, the way to "send the bugs to us" is via SourceForge:

Known bugs that probably won't get fixed:
BadWords' outFilter filters colors. It's not a high priority to get
that fixed.

These are the developers of Supybot, in approximate order of ____.
Jeremy Fincher (jemfinch) is a Computer Science (and possibly
philosophy) student at The Ohio State University. He spends most of
his free time with his girlfriend Meg, but also...well, there's not
much also :) He hopes to graduate with good enough grades to go to
law school or seminary at some point in the future. He initially
wrote the majority of the Supybot framework and standard plugins,
though he's been trying to slowly phase himself out of plugin-writing
and more into framework-enhancement. Rather than list the specific
things he's done, you can just assume that if someone else isn't
claiming it, it was probably done by him.
Daniel DiPaolo (Strike/ddipaolo) is a lazy Texan punk with a job as an IT
monkey who spends his free time coding, playing ultimate frisbee, and arguing
pointless things on the internet. As far as the bot goes, he's mainly a
plugin developer but he has helped here and there with various under-the-hood
things and is one of the few people (other than jemfinch) who understands the
inner workings of Supybot. His biggest plugin contribution (in terms of sheer
lines of code) has been the MoobotFactoids plugin and all the workd involved
in getting that plugin to work, but he has also helped with a lot of testing,
debugging, and brainstorming. He also wrote the Dunno, News, and Todo plugins
and is responsible for a significant amount of code in the Poll, Debian,
QuoteGrabs, Karma, and ChannelDB plugins.
James Vega (jamessan) is an Electrical Engineering/Computer Science student at
Northeastern University. He wrote the Sourceforge and Ebay plugins as well as
the first incarnation of the Babelfish commands and most of Amazon. He has
also performed a significant amount of maintenance and refactoring of plugins
in general. Some of the plugins that were affected the most are Debian,
FunDB, Gameknot, Http, Note, and Quote. All of the link snarfers, save
Bugzilla's, were also written by jamessan. His meddlings have prompted the
implementation of Toggleables, which eventually evolved to Configurables and
then to the current registry system. As well as being the current webmaster,
he also overhauled the tool which is used to generate the site's HTML
documentation for Supybot and setup the weekly creation of CVS snapshots.
Brett Kelly (inkedmn) is a hobbyist (soon to be professional :)) coder
from southern California who enjoys collecting tattoos (on his body) and
drinking coffee with his wife. He initially wrote the Note plugin as well
as several commands in the Http plugin.
Vincent Foley-Bourgon is a recently-graduated student from Quebec who
enjoys anything pointless, unprofitable, and generally useless. Recently
returning to Supybot development (after writing the original freshmeat
command for the Http plugin) he wrote the entire Hangman infrastructure
for the Words plugin.
Daniel Berlin is a soon to be lawyer with a background in computer science
and compilers. He enjoys selling crack to young homeless orphans, and works
on Supybot when he's not lawyering or hacking on gcc.
Keith Jones (kmj) dislikes talking about himself in the third person. He
has an MS in Computer Science, and has decided to see how long he can go
without using that in any kind of professional capacity. To that end he
is currently taking some math classes and applying to math Ph.D programs
so some day he can be a professor at a college near a snowy mountain where
he will ski every morning. So far, he hasn't done much for the project
except squeeze Doug Bell's GPL'd unit conversion code into a supybot plugin.
Stéphan Kochen (G-LiTe) is a lazy (soon to be) computer science student.
He's usually just freelancing and submitting patches here and there when he
bumps into a bug that bothers him, but Supybot is one of the first projects
he semi-actively tries to work on. ;) His biggest contribution has been the
refactoring of the supybot-wizard script to use the registry, though he also
likes to track down those nasty obscure bugs which haunt many of our fine
applications these days.

So what do you do? That depends on which operating system you're
running. We've split this document up to address the different
methods, so find the section for your operating system and continue
from there. First let's start with the parts that are common to all
OSes.
###
# COMMON:
###
First things first: Supybot *requires* at least Python 2.3. There ain't
no getting around it. We do not require any version greater than 2.3,
but we will be compatible with any version of Python >= 2.3. If you're
a Python developer, you probably know how superior 2.3 is to previous
incarnations. If you're not, just think about the difference between a
bowl of plain vanilla ice cream and a banana split. Or something like
that. Either way, *We're* Python developers and we like banana splits.
So, be sure to install python2.3 or greater before continuing. You can
get it from http://www.python.org/
For more information and help on how to use Supybot, checkout
the documents under docs/ (especially GETTING_STARTED and CONFIGURATION).
Our forums (http://forums.supybot.org/) may also be of use, especially
the "Tips and Tricks" topic under "Supybot User Discussion".
###
# UNIX/Linux/*BSD:
###
If you're installing Python using your distributor's packages, you may
need a python-dev package installed, too. If you don't have a
/usr/lib/python2.3/distutils directory (assuming /usr/lib/python2.3 is
where your Python libs are installed), then you will need a python-dev
package.
After you extract Supybot and cd into the supybot directory just
created, you'll want to run (as root) "python setup.py install". This
will install Supybot globally. If you need to install locally for
whatever reason, see the addendum near the end of this document.
You'll then have several new programs installed where Python scripts
are normally installed on your system (/usr/bin or /usr/local/bin are
common on UNIX systems). The two that might be of particular interest
to you, the new user, are "supybot" and "supybot-wizard". The former
("supybot") is the script to run an actual bot; the latter
("supybot-wizard") is an in-depth wizard that provides a nice user
interface for creating a registry file for your bot.
So after running supybot-wizard, you've got a nice registry file
handy. If you're not satisfied with your answers to any of the
questions you were asked, feel free to run the program again until
you're satisfied with all your answers. Once you're satisfied,
though, run the "supybot" program with the registry file you created
as an argument. This will start the bot; unless you turned off
logging to stdout, you'll see some nice log messages describing what
the bot is doing at any particular moment; it may pause for a
significant amount of time after saying "Connecting to ..." while the
server tries to check its ident.
###
# Windows:
###
*** If you are using an IPV6 connection, you will not be able to run
Supybot under Windows (unless Python has fixed things). Current
versions of Python for Windows are *not* built with IPV6 support. This
isn't expected to be fixed until Python 2.4, at the earliest.
Now that you have Python installed, open up a command prompt. The
easiest way to do this is to open the run dialog (Programs -> run) and
type "cmd" (for Windows 2000/XP/2003) or "command" (for Windows 9x).
In order to reduce the amount of typing you need to do, I suggest
adding Python's directory to your path. If you installed Python using
the default settings, you would then do the following in the command
prompt (otherwise change the path to match your settings):
set PATH=%PATH%;C:\Python23\
You should now be able to type "python" to start the Python
interpreter (CTRL-Z and Return to exit). Now that that's setup,
you'll want to cd into the directory that was created when you
unzipped Supybot; I'll assume you unzipped it to C:\Supybot for these
instructions. From C:\Supybot, run "python setup.py install". This
will install Supybot under C:\Python23\. If you want to install
Supybot to a non-default location, see the addendum near the end of
this document. You will now have several new programs installed in
C:\Python23\Scripts\. The two that might be of particular interest to
you, the new user, are "supybot" and "supybot-wizard". The former
("supybot") is the script to run an actual bot; the latter
("supybot-wizard") is an in-depth wizard that provides a nice user
interface for creating a registry file for your bot.
Now you will want to run "python C:\Python23\Scripts\supybot-wizard"
to generate a registry file for your bot. So after running
supybot-wizard, you've got a nice registry file handy. If you're not
satisfied with your answers to any of the questions you were asked,
feel free to run the program again until you're satisfied with all
your answers. Once you're satisfied, though, run "python
C:\Python23\Scripts\supybot botname.conf". This will start the bot;
unless you turned off logging to stdout, you'll see some nice log
messages describing what the bot is doing at any particular moment; it
may pause for a significant amount of time after saying "Connecting
to ..." while the server tries to check its ident.

EVERYONE:
---------
Read LICENSE. It's a 2-clause BSD license, but you should read it anyway.
USERS:
------
If you're upgrading, read RELNOTES. If you're new to Supybot,
read docs/GETTING_STARTED for an introduction to the bot, and read
docs/CAPABILITIES to see how to use capabilities to your greater
benefit.
If you have any trouble, feel free to swing by #supybot on
irc.freenode.net or irc.oftc.net (we have a Supybot there relaying,
so either network works) and ask questions. We'll be happy to help
wherever we can. And by all means, if you find anything hard to
understand or think you know of a better way to do something,
*please* post it on Sourceforge.net so we can improve the bot!
WINDOWS USERS:
--------------
The wizards (supybot-wizard, supybot-newplugin, and
supybot-adduser) are all installed to your Python directory's
\Scripts. What that *probably* means is that you'll run them like
this: C:\Python23\python C:\Python23\Scripts\supybot-wizard
DEVELOPERS:
-----------
Read OVERVIEW to see what the modules are used for. Read PLUGIN-EXAMPLE
to see some examples of callbacks and commands written for the bot.
Read INTERFACES to see what kinds of objects you'll be dealing with.
Read STYLE if you wish to contribute; all contributed code must meet
the guidelines set forth there.
Be sure to run "test/test.py --help" to see what options are available
to you when testing. Windows users in particular should be sure to
exclude test_Debian.py and test_Unix.py.

Version 0.80.1
Bugfix release. No incompatibilities.
Version 0.80.0
We *finally* hit 0.80.0! This release is completely compatible with
the last release candidate.
An update to Babelfish may cause an error message to be displayed in
the console when the bot is first run. The error message should be
gone when the bot is restarted.
We also have a new community website at http://www.supybot.com/ where
our users can submit their own plugins, view/download other people's
plugins and discuss all things Supybot-related.
Version 0.80.0rc3
Another bugfix release. This one was pretty important as it actually
makes supybot.database.plugins.channelSpecific work properly.
Version 0.80.0rc2
supybot.databases.plugins.channelSpecific.channel was renamed to
supybot.databases.plugins.channelSpecific.link.
supybot.databases.plugins.channelSpecific.link.allow was added, which
determines whether a channel will allow other channels to link to its
database.
Infobot is no longer deprecated and the following changes were made to
its config variables:
supybot.plugins.Infobot.answerUnaddressedQuestions was renamed to
supybot.plugins.Infobot.unaddressed.answerQuestions.
supybot.plugins.Infobot.snarfUnaddressedDefinitions was renamed to
supybot.plugins.Infobot.unaddressed.snarfDefinitions.
supybot.plugins.Infobot.unaddressed.replyExistingFactoid was added to
determine whether the bot will reply when someone attempts to create a
duplicate factoid.
Version 0.80.0pre6
Another bugfix release. No incompatibilities known. The only
registry change is that supybot.databases.users.hash has been
removed.
Version 0.80.0pre5
Completely bugfix release. No incompatibilies known.
Version 0.80.0pre4
Mainly a bug fix release. This will likely be the last release before
0.80.0final, but we're gonna let it stew for a couple weeks to attempt
to catch any lingering bugs.
ansycoreDrivers is now deprecated in favor of socketDrivers or
twistedDrivers.
supybot.databases.plugins.channelSpecific.channel is now a channelValue
so that you can link specific channels together (instead of all channels
being linked together).
For those of you that use eval and/or exec, they have been removed from
the Owner plugin and are now in sandbox/Debug.py (which you'll have to
grab from CVS).
Version 0.80.0pre3
The database format for the Note plugin has changed to a flatfile
format; use tools/noteConvert.py to convert it to the new format.
Ditto that for the URL database.
FunDB is deprecated and will be removed at the next major release;
use tools/fundbConvert.py to convert your old FunDB databases to Lart
and Praise databases.
If you had turned off supybot.databases.plugins.channelSpecific, your
non-channel-specific database files had gone directly into your data/
directory. We had some problems with poor interactions between that
configuration variable and channel capabilities, though, so we
changed the implementation so that non-channel-specific databases are
considered databases of a single (configurable) channel (defaulting
to "#"). This will also help others who are converting from
channel-specific to non-channel-specific databases, but for you
who've already made the switch, you'll need to move your database
files again, from data/ to data/# (or whatever channel you might
change that variable to).
supybot.channels doesn't exist anymore; now the only list of channels
to join is per-network, in supybot.networks.<network>.channels.
We weren't serializing supybot.replies.* properly in older versions.
Now we are, but the old, improperly serialized versions won't work
properly. Remove from your configuration file all variables
beginning with "supybot.replies" before you start the bot.
The URL database has been changed again, but it will use a different
filename so you shouldn't run into conflicts, just a newly-empty
database.
We upgraded the SOAP stuff in others; you may do well to do a
setup.py install --clean this time around.
Version 0.80.0pre2
Many more bugs have been fixed. A few more plugins have been updated
to use our new-style database abstraction. If it seems like your
databases are suddenly empty, look for a new database file named
Plugin.dbtype.db. We've also added a few more configuration variables.
Version 0.80.0pre1
Tons of bugs fixed, many features and plugins added. Everything
should be entirely compatible; many more configuration variables have
been added.
Version 0.79.9999
Some more bugs fixed, added a few features and a couple configuration
variabless. This should hopefully be the last release before 0.80.0,
which will finally bring us to pure Beta status.
Version 0.79.999
Some bugs fixed, but the ones that were fixed were pretty big. This
is, of course, completely compatible with the last release.
Version 0.79.99
Many bugs fixed, thanks to the users who reported them. We're
getting asymptotically closer to 0.80.0 -- maybe this'll be the last
one, maybe we'll have to release an 0.79.999 -- either way, we're
getting close :) Check out the ChangeLog for the fixes and a few new
features.
Version 0.79.9
We've changed so much stuff in this release that we've given up on
users upgrading their configuration files for the new release. So
do a clean install (python2.3 setup.py install --clean), run the
wizard again, and kick some butt.
(It's rumored that you can save most of your old configuration by
appending your new configuration at the end of your old configuration
and running supybot with that new configuration file. This, of
course, comes with no warranty or guarantee of utility -- try it if
you want, but backup your original configuration file!)
Version 0.77.2
This is a drop-in replacement for 0.77.1, with two exceptions. The
configuration variable formerly known as
"supybot.plugins.Services.password" is now known as
"supybot.plugins.Services.NickServ.password", due to the fact that
there might be different passwords for NickServ and ChanServ (and
ChanServ passwords are per-channel, whereas NickServ passwords are
global). If you're using the Services plugin, you'll need to make
this change in order to continue identifying with services. The
configuration variable formerly known as
"supybot.plugins.Babelfish.disabledLanguages" is now known as
"supybot.plugins.Babelfish.languages". The configuration variable now
accepts the languages that *will* be translated as opposed to ones
that are *not* translated.
Tests and the developer sandbox are not longer delivered with our
release tarballs. If you're a developer and you want these, you
should either check out CVS or download one of our weekly CVS
snapshots, available at http://supybot.sourceforge.net/snapshots/ .
Version 0.77.1
This is a drop-in replacement for 0.77.0 -- no incompatibilities, to
out knowledge. Simply install over your old installation and restart
your bot :)
Version 0.77.0
Setup.py will automatically remove your old installations for you, no
need to worry about that yourself.
Configuration has been *entirely* redone. Read the new
GETTING_STARTED document to see how to work with configuration
variables now. Your old botscripts from earlier versions *will not*
work with the new configuration method. We'd appreciate it if you'd
rerun the wizard in order for us to find any bugs that remain in it
before we officially declare ourselves Beta. Note also that because
of the new configuration method, the interface for plugins' configure
function has changed: there are no longer any onStart or afterConnect
arguments, so all configuration should be performed via the registry.
Channel capabilities have been changed; rather than being
#channel.capability, they're now #channel,capability. It's a bit
uglier, we know, but dots can be valid in channel names, and we
needed the dot for handling plugin.command capabilities.
tools/ircdbConvert.py should update this for you.
The on-disk format of the user/channel databases has changed to be far
more readable. A conversion utility is included, as mentioned before:
tools/ircdbConvert.py. Run this with no arguments to see the
directions for using it.
Uh, we were just kidding about the upgrade script in 0.76.0 :) It'll
be a little while longer. We do have several little upgrade scripts,
though.
Version 0.76.1
Almost entirely bugfixes, just some minor (and some less minor) bugs
that need to get in before we really start hacking on the next
version. Should be *entirely* compatible with 0.76.0.
Version 0.76.0
Major bugfix release. A great number of bugs fixed. This is the last
release without an upgrade script.
The only hiccup in the upgrade from 0.75.0 should be that you'll need
to update your botscript to reflect the removal of the debug module.
We'd rather you use supybot-wizard to generate a new botscript, of
course, but if you insist on modifying your existing botscript, take a
look at
<http://cvs.sourceforge.net/viewcvs.py/supybot/supybot/src/template.py?r1=1.20&r2=1.21>
to see what you need to do.
Version 0.75.0
Don't forget to reinstall (i.e., run "python setup.py install" as
root). Sometimes it even does good to remove the old installation;
$PYTHON/site-packages/supybot can be removed with no problems
whatsoever.
You will need to re-run supybot-wizard and generate a new botscript.
The Infobot plugin has been removed from this release; it's not ready
for prime time. If you're interested in getting it running (i.e., you
want full Infobot compatibility and aren't satisfied with either
MoobotFactoids or Factoids) then swing over to #supybot and we can
discuss the tests. We simply don't know enough about Infobot to make
sure our Infobot plugin is an exact replica, and need someone's help
with making the changes necessary for that.

TODO
View File

@ -1,40 +0,0 @@
Roughly in order of precedence (the closer to the front of the file,
the more likely it'll be done before next release):
* We should have a channel-global value in ircdb.IrcChannel for
ignoring unregistered users.
* We need to note when bans expire on a channel and send the unban,
that way plugins can use the ircdb ban stuff and not worry about
sending or scheduling unbans.
* We should probably add a "hello" command to make things more
compatible with Eggdrop, since we've been replacing many eggdrop
bots lately.
* We should be able to set the log level for plugins individually.
* Rbot has a "remind" plugin that seems pretty cool, we should get
one as well. It might do well as a command in the Later plugin.
* MozBot has a "list" plugin that seems pretty cool, we should get
one as well.
Problems that involve a lot of tedious minutiae, but really need to
be done at some point:
Hard problems that won't get done until someone really wants to have
some fun:
* Redundant relaying -- having more than one bot handle relaying,
where a secondary one will automatically take over if the first
becomes incapacitated.
* Have the bot detect when other bots are in the channel responding
to the same prefix character, and do something based on that.
* Unicode support. Basically, we'd have to have a way to set the
encoding for the server, and use unicode throughout internally.
The real issue is how much it would affect the current code to
switch it over to unicode, and what kind of burden it would put on
plugin authors to deal with that issue.

Supybot is a robust (it doesn't crash), user friendly (it's easy
to configure) and programmer friendly (plugins are *extremely*
easy to write) Python IRC bot. It aims to be an adequate
replacement for most existing IRC bots. It includes a very
flexible and powerful ACL system for controlling access to
commands, as well as more than 50 builtin plugins providing
around 400 actual commands.

Ok, some explanation of the capabilities system is probably in
order. With most IRC bots (including the ones I've written myself
prior to this one) "what a user can do" is set in one of two ways. On
the *really* simple bots, each user has a numeric "level" and commands
check to see if a user has a "high enough level" to perform some
operation. On bots that are slightly more complicated, users have a
list of "flags" whose meanings are hardcoded, and the bot checks to
see if a user possesses the necessary flag before performing some
operation. Both methods, IMO, are rather arbitrary, and force the
user and the programmer to be unduly confined to less expressive
constructs.
This bot is different. Every user has a set of "capabilities" that is
consulted every time they give the bot a command. Commands, rather
than checking for a user level of 100, or checking if the user has an
"o" flag, are instead able to check if a user has the "owner"
capability. At this point such a difference might not seem
revolutionary, but at least we can already tell that this method is
self-documenting, and easier for users and developers to understand
what's truly going on.
If that was all, well, the capability system would be "cool", but not
many people would say it was "awesome". But it *is* awesome! Several
things are happening behind the scene that make it awesome, and these
are things that couldn't happen if the bot was using numeric
userlevels or single-character flags. First, whenever a user issues
the bot a command, the command dispatcher checks to make sure the user
doesn't have the "anticapability" for that command. An anticapability
is a capability that, instead of saying "what a user can do", says
what a user *cannot* do. It's formed rather simply by adding a dash
("-") to the beginning of a capability; "rot13" is a capability, and
"-rot13" is an anticapability. Anyway, when a user issues the bot a
command, perhaps "calc" or "help", the bot first checks to make sure
the user doesn't have the "-calc" or the "-help" capabilities before
even considering responding to the user. So commands can be turned on
or off on a *per user* basis, offering fine-grained control not often
(if at all!) seen in other bots.
But that's not all! The capabilities system also supports *Channel*
capabilities, which are capabilities that only apply to a specific
channel; they're of the form "#channel,capability". Whenever a user
issues a command to the bot in a channel, the command dispatcher also
checks to make sure the user doesn't have the anticapability for that
command *in that channel*, and if the user does, the bot won't respond
to the user in the channel. Thus now, in addition to having the
ability to turn individual commands on or off for an individual user,
we can now turn commands on or off for an individual user on an
individual channel!
So when a user "foo" sends a command "bar" to the bot on channel
"#baz", first the bot checks to see if the user has the anticapability
for the command by itself, "-bar". If so, it returns right then and
there, completely ignoring the fact that the user issued that command
to it. If the user doesn't have that anticapability, then the bot
checks to see if the user issued the command over a channel, and if
so, checks to see if the user has the antichannelcapability for that
command, "#baz,-bar". If so, again, he returns right then and there
and doesn't even think about responding to the bot. If neither of
these anticapabilities are present, then the bot just responds to the
user like normal.
From a programming perspective, capabilties are easy to use and
flexible. Any command can check if a user has any capability, even
ones not thought of when the bot was originally written.
Commands/Callbacks can add their own capabilities -- it's as easy as
just checking for a capability and documenting somewhere that a user
needs that capability to do something.
From an end-user perspective, capabilities remove a lot of the mystery
and esotery of bot control, in addition to giving the user absolutely
finegrained control over what users are allowed to do with the bot.
Additionally, defaults can be set by the end-user for both individual
channels and for the bot as a whole, letting an end-user set the
policy he wants the bot to follow for users that haven't yet
registered in his user database. It's really a revolution!
There are several default capabilities the bot uses. The most
important of these is the "owner" capability. This capability allows
the person having it to use *any* command. It's best to keep this
capability reserved to people who actually have access to the shell
the bot is running on.
There is also the "admin" capability for non-owners that are highly
trusted to administer the bot appropriately. They can do things such
as change the bot's nick, globally enable/disable commands, cause the
bot to ignore a given user, set the prefixchar, report bugs, etc.
They generally cannot do administration related to channels, which is
reserved for people with the next capability.
People who are to administer channels with the bot should have the
#channel,op capability -- whatever channel they are to administrate,
they should have that channel capability for "op". For example, since
I want inkedmn to be an administrator in #supybot, I'll give him the
#supybot,op capability. This is in addition to his admin capability,
since the admin capability doesn't give the person having it control
over channels. #channel,op is used for such things as
giving/receiving ops, kickbanning people, lobotomizing the bot,
ignoring users in the channel, and managing the channel capabilities.
The #channel,op capability is also basically the equivalent of the
owner capability for capabilities involving #channel -- basically
anyone with the #channel,op capability is considered to have all
positive capabilities and no negative capabilities for #channel.
One other globally important capability exists: "trusted". This is a
command that basically says "This user can be trusted not to try and
crash the bot." It allows users to call commands like Math.icalc,
which potentially could cause the bot to begin a calculation that
could potentially never return (a calculation like 10**10**10**10).
Another command that requires the trusted capability is Utilties.re,
which (due to the regular expression implementation in Python (and any
other language that uses NFA regular expressions, like Perl or Ruby or
Lua or ...) which can allow a regular expression to take exponential
time to process). Consider what would happen if someone gave the
bot the command 're [format join "" s/./ [dict go] /] [dict go]'
Other plugins may require different capabilities; the Factoids plugin
requires #channel,factoids, the Topic plugin requires #channel,topic,
etc.

So you've got your Supybot up and running and there are some things
you don't like about it. Fortunately for you, chances are that these
things are configurable, and this document is here to tell you how to
configure them.
Configuration of Supybot is handled via the Config plugin, which
controls runtime access to Supybot's registry (the configuration file
generated by the supybot-wizard program you ran). The Config plugin
provides a way to get or set variables, to list the available
variables, and even to get help for certain variables. Take a moment
now to read the help for each of those commands: config, list, and
help. If you don't know how to get help on those commands, go ahead
and read our GETTING_STARTED document before this one.
Now, if you're used to the Windows registry, don't worry, Supybot's
registry is completely different. For one, it's completely plain
text. There's no binary database sensitive to corruption, it's not
necessary to use another program to edit it -- all you need is a
simple text editor. But there is at least one good idea in Windows'
registry: hierarchical configuration. Supybot's configuration
variables are organized in a hierarchy: variables having to do with
the way Supybot makes replies all start with supybot.reply; variables
having to do with the way a plugin works all start with
supybot.plugins.Plugin (where Plugin is the name of the plugin in
question). This hierarchy is nice because it means the user isn't
inundated with hundreds of unrelated and unsorted configuration
variables.
Some of the more important configuration values are located directly
under the base group, supybot. Things like the bot's nick, its ident,
etc. Along with these config values are a few subgroups that contain
other values. Some of the more prominent subgroups are: plugins
(where all the plugin-specific configuration is held), reply (where
variables affecting the way a Supybot makes its replies resides),
replies (where all the specific standard replies are kept), and
directories (where all the directories a Supybot uses are defined).
There are other subgroups as well, but these are the ones we'll use in
our example.
Using the Config plugin, you can list the values in a subgroup and get
or set any of the values anywhere in the configuration hierarchy. For
example, let's say you wanted to see what configuration values were
under the "supybot" (the base group) hierarchy. You would simply
issue this command:
<jemfinch|lambda> @config list supybot
<supybot> @capabilities, @commands, @databases, @debug, @directories, @drivers,
@log, @networks, @nick, @plugins, @protocols, @replies, @reply,
alwaysJoinOnInvite, channels, defaultIgnore, defaultSocketTimeout,
externalIP, flush, followIdentificationThroughNickChanges,
humanTimestampFormat, ident, pidFile, snarfThrottle, upkeepInterval,
and user
These are all the configuration groups and values which are under the
base "supybot" group. Actually, their full names would each have a
"supybot." appended on to the front of them, but it is omitted in the
listing in order to shorten the output. The first entries in the output are
the groups (distinguished by the @ symbol in front of them), and the rest are
the configuration values.
Okay, now that you've used the Config plugin to list configuration
variables, it's time that we start looking at individual variables and
their values.
The first (and perhaps most important) thing you should know about
each configuration variable is that they all have an associated help
string to tell you what they represent. So the first command we'll
cover is "config help". To see the help string for any value or
group, simply use the "config help" command. For example, to see what
this "supybot.snarfThrottle" configuration variable is all about, we'd
do this:
<jemfinch|lambda> @config help supybot.snarfThrottle
<supybot> jemfinch|lambda: A floating point number of seconds to throttle snarfed
URLs, in order to prevent loops between two bots snarfing the same URLs and
having the snarfed URL in the output of the snarf message. (Current value:
10.0)
Pretty simple, eh?
Now, if you're curious what the current value of a configuration
variable is, you'll use the "config" command with one argument, the
name of the variable you want to see the value of:
<jemfinch|lambda> @config supybot.reply.whenAddressedBy.chars
<supybot> jemfinch|lambda: '@'
To set this value, just stick an extra argument after the name:
<jemfinch|lambda> @config supybot.reply.whenAddressedBy.chars @$
<supybot> jemfinch|lambda: The operation succeeded.
Now, check this out:
<jemfinch|lambda> $config supybot.reply.whenAddressedBy.chars
<supybot> jemfinch|lambda: '@$'
Note that we used $ as our prefix character, and that the value of the
configuration variable changed. If I were to use the "flush" command
now, this change would be flushed to the registry file on disk (this
would also happen if I made the bot quit, or pressed Ctrl-C in the
terminal the bot was running in). Instead, I'll revert the change:
<jemfinch|lambda> $config supybot.reply.whenAddressedBy.chars @
<supybot> jemfinch|lambda: The operation succeeded.
<jemfinch|lambda> $note that this makes no response.
If you're ever curious what the default for a given configuration
variable is, use the "config default" command:
<jemfinch|lambda> @config default supybot.reply.whenAddressedBy.chars
<supybot> jemfinch|lambda: ''
Thus, to reset a configuration variable to its default value, you can
simply say:
<jemfinch|lambda> @config supybot.reply.whenAddressedBy.chars [config
default supybot.reply.whenAddressedBy.chars]
<supybot> jemfinch|lambda: The operation succeeded.
<jemfinch|lambda> @note that this does nothing
Simple, eh?
Now, let's say you want to find all configuration variables that might
be even remotely related to opping. For that, you'll want the "config
search" command. Check this out:
<jemfinch|lambda> @config search op
<supybot> jemfinch|lambda:
supybot.plugins.Enforcer.autoOp,
supybot.plugins.Enforcer.autoHalfop,
supybot.plugins.Enforcer.takeRevenge.onOps,
supybot.plugins.Enforcer.cycleToGetOps,
supybot.plugins.Topic, supybot.plugins.Topic.public,
supybot.plugins.Topic.separator,
supybot.plugins.Topic.format,
supybot.plugins.Topic.recognizeTopiclen,
supybot.plugins.Topic.default,
supybot.plugins.Topic.undo.maz, and
supybot.plugins.Relay.topicSync
Sure, it showed up all the topic-related stuff in there, but it also
showed you all the op-related stuff, too. Do note, however, that you
can only see configuration variables for plugins that you have loaded
or that you loaded in the past; if you've never loaded a plugin,
there's no way for the bot to know what configuration variables it
registers.
Some people might like editing their registry file directly rather
than manipulating all these things through the bot. For those people,
we offer the "config reload" command, which reloads both registry
configuration and user/channel/ignore database configuration. Just
edit the interesting files and then give the bot the "config reload"
command and it'll work as expected. Do note, however, that Supybot
flushes his configuration files and databases to disk every hour or
so, and if this happens after you've edited your configuration files
but before you reload your changes, you could lose the changes you
made. To prevent this, set the supybot.flush value to Off, and no
automatic flushing will occur.
Many configuration variables can be specific to individual channels.
The Config plugin provides an easy way to configure something for a
specific channel; for instance, in order to set the prefix chars for a
specific channel, do this in that channel:
config channel supybot.reply.whenAddressedBy.chars !
That'll set the prefix chars in the channel that message is sent in to
!. Voila, channel-specific values! Also, note that when using the
Config plugin's list command, channel-specific values are preceded by
a '#' character to indicate such.
Anyway, that's about it for configuration. Have fun, and enjoy your
configurable bot!

The Official Supybot DocBook Metadocumentation
(or, How Does One SGML File Turn Into All Those Document Formats?)
Okay, though this isn't the case yet, ideally all of Supybot's documentation
can and will be done using DocBook and DocBook-related tools as well as a few
custom extensions that I've written.
- How does DocBook work?
First things first, you have to understand sort of how DocBook works in order
to figure out how our documentation gets generated from just one file. What
DocBook is, basically, is just a DTD (Document Type Definition). What that
means is that it simply specifies how a document can be structured and still be
considered a valid document by placing restrictions on what elements go where.
It's a popular DTD because it is structured very well and it's not only fairly
generic, but it also has nice elements that make documenting things (such as
supybot) rather easy. It focuses on structure and content instead of
presentation which is what makes it nice for writing things which are output
format agnostic.
So, let's say we've written a proper DocBook document, now what? Well, using
an output formatting tool and a stylesheet, you create whatever form of output
you want. What we use for producing the outptut is jade, and DocBook comes
with a few stylesheets that work with that tool to create output formats like
HTML and TeX. From the TeX file we produce a DVI (device independent) file
with latex, and from that we produce the print formats of our documents, like
PDF and Postscript using tools like dvips and dvipdfm.
- What extra stuff do we do?
Well, since our documents all have to do with an IRC bot, there are some very
common things that we talk about a lot that we might like to format specially.
For example, when we discuss a particular command for the bot we might like to
have that text appear slightly different to emphasize the fact that it is
special. So, for the commonly used items that weren't already covered by
DocBook's DTD, I added elements into a new DTD which just extends DocBook's
DTD. So now we have elements like <nick> and <channel> and <botcommand> that
we can use for our documentation.
Of course, now that we have used a DTD with more stuff in it (than DocBook),
the stylesheets that DocBook provides won't do any special formatting for those
new elements so we have to write new stylesheets as well. Once again I just
extended the existing ones with formatting instructions on how to treat the new
elements. So with this done, now our HTML and TeX (and whatever else) output
will be properly formatted.
- How do I make my own changes to the DTD and stylesheets?
Primarily, you don't :) Ask me (Strike) first about it, and I will generally
write them for you or explain a better way of doing things. This is especially
true for the DTD, because that must remain consistent everywhere we write/read
supybot docs based on it. The stylesheets are more lax and can be modified to
produce whatever kind of output you wish.
So, with that warning/reminder out of the way, here's how to modify each
anyway. This doesn't really assume any knowledge of how to write a DTD, nor is
it an exhaustive reference on writing one, so don't treat it as such. I'm
basically just going to explain how to add extra elements that will play well
with the DocBook DTD.
-- Adding an element to the DTD
If you've decided that there's a certain "thing" that's mentioned a lot in the
documentation and deserves classification (for potential special formatting),
you'll probably want to create a new element (or set of elements) for it. I'll
walk you through how I added the "nick" element to our DTD (though many/most of
the elements I added follow an identical process).
The very first thing you need to figure out is: where in my document does this
element "fit". That is to say, what elements should/can rightly contain this
particular one? In the case of the "nick" element, it's basically always an
inline-formatted deal that belongs in paragraphs for the most part. For those
of you scratching your heads at that last sentence, perhaps thinking "okay, so
how are we supposed to know what is relevant?" I say, "don't worry, I learned
by example as well." Basically, I just looked through the DocBook DTD and
figured out where things belong. Now, even if you don't know the DocBook DTD
front-to-back, you can still peruse it to figure out where your new element
belongs. Obviously, you should probably know *some* DocBook to figure out what
each element means, but luckily all of our docs have been converted to DocBook
and serve as nice examples of the usage of many elements :)
Now, to figure out where something like "nick" belongs. In many ways, a nick
is sort of like a variable name (at least in documentation usage). So, the
element I chose to base it off of was "varname". If you have the DocBook DTD
installed (as you should if you intend on making extensions to it), the varname
element definition is contained in the dbpoolx.mod filename (in Debian, it's
under /usr/share/sgml/docbook/dtd/4.2). How did I know this? Well, grep is
your friend and mine too, and dbpoolx is the only filename that shows up when
grepping for "varname" in the DocBook DTD directory. So, we open up dbpoolx.mod and search for varname. The first thing we find it in looks like this:
<!ENTITY % tech.char.class
"action|application
|classname|methodname|interfacename|exceptionname
|ooclass|oointerface|ooexception
|command|computeroutput
|database|email|envar|errorcode|errorname|errortype|errortext|filename
|function|guibutton|guiicon|guilabel|guimenu|guimenuitem
|guisubmenu|hardware|interface|keycap
|keycode|keycombo|keysym|literal|constant|markup|medialabel
|menuchoice|mousebutton|option|optional|parameter
|prompt|property|replaceable|returnvalue|sgmltag|structfield
|structname|symbol|systemitem|token|type|userinput|varname
%ebnf.inline.hook;
%local.tech.char.class;">
Hmm, this doesn't look like a definition of varname (to me, but I sort of
cheated by having read about DocBook before-hand ;)), but it will be important
to remember for later. Let's try and find the element definition for varname
(so, basically, let's look for the first line that starts with "<!ELEMENT ").
The first line I come up with when I search is:
<!ELEMENT varname %ho; (%smallcptr.char.mix;)*>
Rather than write a separate tutorial for interpreting DTDs, I found a good
SGML tutorial online that explains everything necessary to help you parse the
DocBook DTD to figure out what the varname element really is, as well as to
help you learn all the stuff necessary for what we will cover in creating our
new nick element. That tutorial is at
http://www.w3.org/TR/WD-html40-970708/intro/sgmltut.html#howtodtd (it's for
reading the HTML DTD, but it applies to any DTD).
So, now that we understand how to write/read things for a DTD, we arrive at the
time where we can write the actual definition of our "nick" element:
<!ELEMENT Nick - - ((%smallcptr.char.mix;)+)>
As we learned in the above tutorial, this means that we are creating an element
named "nick", which must have start and end tags, and is defined to contain one
or more of whatever is in "smallcptr.char.mix". And rather than hunt through
the DocBook DTD to figure out what that is, for now we'll just live with the
fact that whatever can go into a DocBook varname can go into our new nick
element. If you feel so inclined, feel free to try and define the content
model for nick to only include valid nick characters. It's perfectly doable,
and I'll probably do it at some point but I haven't yet.
Since we're extending the DocBook DTD, I also decided that it'd be nice to
follow the element creation conventions observed in their DTD, so there are a
few more lines associated with our new nick element. All of them are related
to the attributes of the element, and allowing for them to be extended by
external DTDs (much like we are doing, only we aren't changing attributes of
existing elements, just adding our own). The first one is:
<!ENTITY % local.nick.attrib "">
This basically defines an empty entity named local.nick.attrib which we will
include so that if anyone chooses to extend the nick attributes, all they have
to do is redefine local.nick.attrib.
<!ENTITY % nick.role.attrib "%role.attrib;">
To tell you the truth, I'm not entirely sure what this is for, but it follows the DocBook convention :)
<!ATTLIST Nick
%common.attrib;
%local.nick.attrib;
%nick.role.attrib;
>
This is, of course, our attribute list for our nick element. It consists of
the two things we just defined as well as common.attrib which contains things
like "id" and whatnot which all DocBook elements are expected to have.
-- Extending the DocBook DTD to recognize new elements
So, that's all you need to define your new element. But, we're not done just
yet! We're almost there, we just need to make it so that it works with the
existing DocBook elements, otherwise it's no good to us. Since we defined our
element to esentially be the same as varname, it probably belongs at the same
place within the DocBook schema as varname. Do you remember when we had that
large entity definition that wasn't what we were looking for at the time though
I said it'd be important later? Well, later is now. So, what that line tells
us is what class of elements DocBook has varname in, which is
"tech.char.class". And thanks to the DocBook convention of defining a
local.<classname> entity that we can extend, all we have to do is redefine
local.tech.char.class to contain "nick", and we are done.
You may notice, however, that we don't actually put varname right into the
local.tech.char.class entity, but instead we create our own
supybot.tech.char.class class of elements that are supybot-specific (and are
the equivalent of DocBook's tech.char.class elements) and instead, put all of
those into the local.tech.char.class entity. Basically, we just go through one
more level of indirection.

<title>Introduction</title>
<subtitle>
Supybot's capabilities overview and comparisons to other bots
</subtitle>
<para>
Ok, some some explanation of the capabilities system is probably
in order. With most IRC bots (including the ones I've written
myself prior to this one) &ldquo;what a user can do&rdquo; is set
in one of two ways. On the <emphasis>really</emphasis> simple
bots, each user has a numeric &ldquo;level&rdquo; and commands
check to see if a user has a &ldquo;high enough level&rdquo; to
perform some operation. On bots that are slightly more
complicated, users have a list of &ldquo;flags&rdquo; whose
meanings are hardcoded, and the bot checks to see if a user
possesses the necessary flag before performing some operation.
Both methods, IMO, are rather arbitrary, and force the user and
the programmer to be unduly confined to less expressive
constructs.
</para>
<para>
This bot is different. Every user has a set of
&ldquo;capabilities&rdquo; that is consulted every time they give
the bot a command. Commands, rather than checking for a user
level of 100, or checking if the user has an <varname>o</varname>
flag, are instead able to check if a user has the
<capability>owner</capability> capability. At this point such a
difference might not seem revolutionary, but at least we can
already tell that this method is self-documenting, and easier for
users and developers to understand what's truly going on.
</para>
</sect1>
<sect1>
<title>What sets supybot's capabilities apart</title>
<para>
If that was all, well, the capability system would be
&ldquo;cool&rdquo;, but not many people would say it was
&ldquo;awesome&rdquo;. But it <emphasis>is</emphasis> awesome!
Several things are happening behind the scene that make it
awesome, and these are things that couldn't happen if the bot was
using numeric userlevels or single-character flags. First,
whenever a user issues the bot a command, the command dispatcher
checks to make sure the user doesn't have the
&ldquo;anticapability&rdquo; for that command. An anticapability is
a capability that, instead of saying &ldquo;what a user can
do&rdquo;, says what a user <emphasis>cannot</emphasis> do. It's
formed rather simply by adding a dash (&ldquo;-&rdquo;) to the
beginning of a capability; <botcommand>rot13</botcommand> is a
capability, and <botcommand>-rot13</botcommand> is an
anticapability. Anyway, when a user issues the bot a command,
perhaps <botcommand>calc</botcommand> or
<botcommand>help</botcommand>, the bot first checks to make sure
the user doesn't have the <capability>-calc</capability> or the
<capability>-help</capability> capabilities before even
considering responding to the user. So commands can be turned on
or off on a <emphasis>per user</emphasis> basis, offering
finegrained control not often (if at all!) seen in other bots.
</para>
<sect2>
<title>Channel capabilities</title>
<para>
But that's not all! The capabilities system also supports
<emphasis>Channel</emphasis> capabilities, which are
capabilities that only apply to a specific channel; they're of
the form <capability>#channel,capability</capability>.
Whenever a user issues a command to the bot in a channel, the
command dispatcher also checks to make sure the user doesn't
have the anticapability for that command <emphasis>in that
channel</emphasis> and if the user does, the bot won't respond
to the user in the channel. Thus now, in addition to having
the ability to turn individual commands on or off for an
individual user, we can now turn commands on or off for an
individual user on an individual channel!
</para>
<para>
So when a user <nick>foo</nick> sends a command
<botcommand>bar</botcommand> to the bot on channel
<channel>#baz</channel>, first the bot checks to see if the
user has the anticapability for the command by itself,
<capability>-bar</capability>. If so, it returns right then
and there, compltely ignoring the fact that the user issued
that command to it. If the user doesn't have that
anticapability, then the bot checks to see if the user issued
the command over a channel, and if so, checks to see if the
user has the antichannelcapability for that command,
<capability>#baz,-bar</capability>. If so, again, he returns
right then and there and doesn't even think about responding
to the bot. If neither of these anticapabilities are present,
then the bot just responds to the user like normal.
</para>
</sect2>
</sect1>
<sect1>
<title>Motivations behind the capabilities system</title>
<sect2>
<title>A programmer's perspective</title>
<para>
From a programming perspective, capabilties are easy to use
and flexible. Any command can check if a user has any
capability, even ones not thought of when the bot was
originally written. Commands/Callbacks can add their own
capabilities &ndash; it's as easy as just checking for a
capability and documenting somewhere that a user needs that
capability to do something.
</para>
</sect2>
<sect2>
<title>An end-user's perspective</title>
<para>
From an end-user perspective, capabilities remove a lot of the
mystery and esotery of bot control, in addition to giving the
user absolutely finegrained control over what users are
allowed to do with the bot. Additionally, defaults can be set
by the end-user for both individual channels and for the bot
as a whole, letting an end-user set the policy he wants the
bot to follow for users that haven't yet registered in his
user database.
</para>
</sect2>
<para>
It's really a revolution!
</para>
</sect1>
<sect1>
<title>Hard-coded supybot capabilities</title>
<para>
There are several default capabilities the bot uses. The most
important of these is the <capability>owner</capability>
capability. This capability allows the person having it to use
<emphasis>any</emphasis> command. It's best to keep this
capability reserved to people who actually have access to the
shell the bot is running on.
</para>
<para>
There is also the <capability>admin</capability> capability for
non-owners that are highly trusted to administer the bot
appropriately. They can do things such as change the bot's nick,
globally enable/disable commands, cause the bot to ignore a given
user, set the prefixchar, report bugs, etc. They generally cannot
do administration related to channels, which is reserved for
people with the next capability.
</para>
<para>
People who are to administer channels with the bot should have the
<capability>#channel,op</capability> capability &ndash; whatever
channel they are to administrate, they should have that channel
capability for <capability>op</capability>. For example, since I
want <nick>inkedmn</nick> to be an administrator in
<channel>#supybot</channel>, I'll give him the
<capability>#supybot,op</capability> capability. This is in
addition to his <capability>admin</capability> capability, since
the <capability>admin</capability> capability doesn't give the
person having it control over channels.
<capability>#channel.op</capability> is used for such things as
giving/receiving ops, kickbanning people, lobotomizing the bot,
ignoring users in the channel, and managing the channel
capabilities. The <capability>#channel,op</capability> capability
is also basically the equivalent of the owner capability for
capabilities involving <channel>#channel</channel> &ndash;
basically anyone with the <capability>#channel,op</capability>
capability is considered to have all positive capabilities and no
negative capabilities for <channel>#channel</channel>.
</para>
<para>
One other globally important capability exists:
<capability>trusted</capability>. This is a command that
basically says &ldquo;This user can be trusted not to try and
crash the bot.&rdquo; It allows users to call commands like
<botcommand>Math.icalc</botcommand>, which potentially could cause the
bot to begin a calculation that could potentially never return (a
calculation like 10**10**10**10). Another command that requires
the trusted capability is <botcommand>Utilties.re</botcommand>, which
(due to the regular expression implementation in Python (and any
other language that uses NFA regular expressions, like Perl or
Ruby or Lua or &hellip;) which can allow a regular expression to
take exponential time to process). Consider what would happen if
the someone gave the bot the command <literal>re [strjoin "" s/./
[dict go] /] [dict go]</literal>.
</para>
</sect1>
<sect1>
<title>Other capabilities</title>
<para>
Other plugins may require different capabilities; the
<plugin>Factoids</plugin> plugin requires
<capability>#channel,factoids</capability>, the <plugin>Topic</plugin>
plugin requires <capability>#channel,topic</capability>, etc.
</para>

<title>Introduction</title>
<para>
So you've got your Supybot up and running and there are some
things you don't like about it. Fortunately for you, chances are
that these things are configurable, and this document is here to
tell you how to configure them.
</para>
<para>
Configuration of Supybot is handled via the
<plugin>Config</plugin> plugin, which controls runtime access to
Supybot's registry (the configuration file generated by the
<script>supybot-wizard</script> program you ran). The
<plugin>Config</plugin> plugin provides a way to get or set
variables, to list the available variables, and even to get help
for certain variables. Take a moment now to read the help for
each of those commands: <botcommand>config</botcommand>,
<botcommand>list</botcommand>, and
<botcommand>help</botcommand>. If you don't know how to get help on
those commands, go ahead and read our
<filename>GETTING_STARTED</filename> document before this one.
</para>
</sect1>
<sect1>
<title>Supybot's registry</title>
<para>
Now, if you're used to the Windows registry, don't worry,
Supybot's registry is completely different. For one, it's
completely plain text. There's no binary database sensitive to
corruption, it's not necessary to use another program to edit it
&ndash; all you need is a simple text editor. But there is at
least one good idea in Windows' registry: hierarchical
configuration. Supybot's configuration variables are organized in
a hierarchy: variables having to do with the way Supybot makes
replies all start with
<registrygroup>supybot.reply</registrygroup>; variables having to
do with the way a plugin works all start with
<registrygroup>supybot.plugins.Plugin</registrygroup> (where
<plugin>Plugin</plugin> is the name of the plugin in question).
This hierarchy is nice because it means the user isn't inundated
with hundreds of unrelated and unsorted configuration variables.
</para>
<para>
Some of the more important configuration values are located
directly under the base group,
<registrygroup>supybot</registrygroup>. Things like the bot's
nick, its ident, etc. Along with these config values are a few
subgroups that contain other values. Some of the more prominent
subgroups are: <registrygroup>plugins</registrygroup> (where all
the plugin-specific configuration is held),
<registrygroup>reply</registrygroup> (where variables affecting
the way a Supybot makes its replies resides),
<registrygroup>replies</registrygroup> (where all the specific
standard replies are kept), and
<registrygroup>directories</registrygroup> (where all the
directories a Supybot uses are defined). There are other
subgroups as well, but these are the ones we'll use in our
example.
</para>
<sect2>
<title>Config plugin commands</title>
<sect3>
<title>Listing registry contents</title>
<para>
Using the <plugin>Config</plugin> plugin, you can list
the values in a subgroup and get or set any of the values
anywhere in the configuration hierarchy. For example,
let's say you wanted to see what configuration values were
under the <registrygroup>supybot</registrygroup> (the base
group) hierarchy. You would simply issue this command:
</para>
<ircsession>
&lt;jemfinch|lambda&gt; @config list supybot
&lt;supybot&gt; @capabilities, @commands, @databases, @debug, @directories, @drivers,
@log, @networks, @nick, @plugins, @protocols, @replies, @reply,
alwaysJoinOnInvite, channels, defaultIgnore, defaultSocketTimeout,
externalIP, flush, followIdentificationThroughNickChanges,
humanTimestampFormat, ident, pidFile, snarfThrottle, upkeepInterval,
and user
</ircsession>
<para>
These are all the configuration groups and values which
are under the base <registrygroup>supybot</registrygroup>
group. Actually, their full names would each have a
&ldquo;supybot.&rdquo; appended on to the front of them,
but it is omitted in the listing in order to shorten the
output. The first entries in the output are the groups
(distinguished by the @ symbol in front of them), and the
rest are the configuration values.
</para>
</sect3>
<sect2>
<title>Supybot's registry</title>
<sect3>
<title>Dealing with registry values</title>
<para>
Okay, now that you've used the <plugin>Config</plugin>
plugin to list configuration variables, it's time that we
start looking at individual variables and their values.
</para>
<sect4>
<title>Built-in help for registry values</title>
<para>
The first (and perhaps most important) thing you
should know about each configuration variable is that
they all have an associated help string to tell you
what they represent. So the first command we'll cover
is <botcommand>config help</botcommand>. To see the
help string for any value or group, simply use the
<botcommand>config help</botcommand> command. For
example, to see what this
<registrygroup>supybot.snarfThrottle</registrygroup>
configuration variable is all about, we'd do this:
</para>
<ircsession>
&lt;jemfinch|lambda&gt; @config help supybot.snarfThrottle
&lt;supybot&gt; jemfinch|lambda: A floating point number of seconds to throttle snarfed
URLs, in order to prevent loops between two bots snarfing the same URLs and
having the snarfed URL in the output of the snarf message. (Current value:
10.0)
</ircsession>
<para>
Pretty simple, eh?
</para>
</sect4>
<sect4>
<title>Getting/setting registry values</title>
<para>
Now, if you're curious what the current value of a
configuration variable is, you'll use the
<botcommand>config</botcommand> command with one
argument, the name of the variable you want to see the
value of:
</para>
<ircsession>
&lt;jemfinch|lambda&gt; @config supybot.reply.whenAddressedBy.chars
&lt;supybot&gt; jemfinch|lambda: '@'
</ircsession>
<para>
To set this value, just stick an extra argument after
the name:
</para>
<ircsession>
&lt;jemfinch|lambda&gt; @config supybot.reply.whenAddressedBy.chars @$
&lt;supybot&gt; jemfinch|lambda: The operation succeeded.
</ircsession>
<para>
Now, check this out:
</para>
<ircsession>
&lt;jemfinch|lambda&gt; $config supybot.reply.whenAddressedBy.chars
&lt;supybot&gt; jemfinch|lambda: '@$'
</ircsession>
<para>
Note that we used <literal>$</literal> as our prefix
character, and that the value of the configuration
variable changed. If I were to use the
<botcommand>flush</botcommand> command now, this
change would be flushed to the registry file on disk
(this would also happen if I made the bot quit, or
pressed
<keycombo>
<keycap>Ctrl</keycap>
<keycap>C</keycap>
</keycombo>
in the terminal the bot was running in). Instead,
I'll revert the change:
</para>
<ircsession>
&lt;jemfinch|lambda&gt; $config supybot.reply.whenAddressedBy.chars @
&lt;supybot&gt; jemfinch|lambda: The operation succeeded.
&lt;jemfinch|lambda&gt; $note that this makes no response.
</ircsession>
<para>
If you're ever curious what the default for a given
configuration variable is, use the <botcommand>config
default</botcommand> command:
</para>
<ircsession>
&lt;jemfinch|lambda&gt; @config default supybot.reply.whenAddressedBy.chars
&lt;supybot&gt; jemfinch|lambda: ''
</ircsession>
<para>
Thus, to reset a configuration variable to its default
value, you can simply say:
</para>
<ircsession>
&lt;jemfinch|lambda&gt; @config supybot.reply.whenAddressedBy.chars [config default
supybot.reply.whenAddressedBy.chars]
&lt;supybot&gt; jemfinch|lambda: The operation succeeded.
&lt;jemfinch|lambda&gt; @note that this does nothing
</ircsession>
<para>
Simple, eh?
</para>
</sect4>
</sect3>
<sect3>
<title>Searching the registry</title>
<para>
Now, let's say you want to find all configuration
variables that might be even remotely related to opping.
For that, you'll want the <botcommand>config
search</botcommand> command. Check this out:
</para>
<ircsession>
&lt;jemfinch|lambda&gt; @config search op
&lt;supybot&gt; jemfinch|lambda:
supybot.plugins.Enforcer.autoOp,
supybot.plugins.Enforcer.autoHalfop,
supybot.plugins.Enforcer.takeRevenge.onOps,
supybot.plugins.Enforcer.cycleToGetOps,
supybot.plugins.Topic, supybot.plugins.Topic.public,
supybot.plugins.Topic.separator,
supybot.plugins.Topic.format,
supybot.plugins.Topic.recognizeTopiclen,
supybot.plugins.Topic.default,
supybot.plugins.Topic.undo.maz, and
supybot.plugins.Relay.topicSync
</ircsession>
<para>
Sure, it showed up all the topic-related stuff in there,
but it also showed you all the op-related stuff, too. Do
note, however, that you can only see configuration
variables for plugins that you have loaded or that you
loaded in the past; if you've never loaded a plugin,
there's no way for the bot to know what configuration
variables it registers.
</para>
<para>
Some people might like editing their registry file
directly rather than manipulating all these things through
the bot. For those people, we offer the
<botcommand>config reload</botcommand> command, which
reloads both registry configuration and
user/channel/ignore database configuration. Just edit the
interesting files and then give the bot the
<botcommand>config reload</botcommand> command and it'll
work as expected. Do note, however, that Supybot flushes
his configuration files and databases to disk every hour
or so, and if this happens after you've edited your
configuration files but before you reload your changes,
you could lose the changes you made. To prevent this, set
the <registrygroup>supybot.flush</registrygroup> value to
<literal>Off</literal>, and no automatic flushing will
occur.
</para>
</sect3>
<sect3>
<title>Channel-specific configuration</title>
<para>
Many configuration variables can be specific to individual
channels. The <plugin>Config</plugin> plugin provides an
easy way to configure something for a specific channel;
for instance, in order to set the prefix chars for a
specific channel, do this in that channel:
</para>
<ircsession>
config channel supybot.reply.whenAddressedBy.chars !
</ircsession>
<para>
That'll set the prefix chars in the channel that message
is sent in to <literal>!</literal>. Voila,
channel-specific values!
</para>
</sect3>
</sect2>
</sect1>
<sect1>
<title>All done!</title>
<para>
Anyway, that's about it for configuration. Have fun, and enjoy
your configurable bot!

<question>
<para>
Why does my bot not recognize me or tell me that I don't
have the <capability>owner</capability> capability?
</para>
</question>
<answer>
<para>
Because you've not given it anything to recognize you
from! You'll need to identify with the bot
(<botcommand>help identify</botcommand> to see how that
works) or add your hostmask to your user record
(<botcommand>help addhostmask</botcommand> to see how that
works) for it to know that you're you. You may wish to
note that <botcommand>addhostmask</botcommand> can accept
a password; rather than identify, you can send the command
<botcommand>addhostmask myOwnerUser [hostmask]
myOwnerUserPassword</botcommand> and the bot will add your
current hostmask to your owner user (of course, you should
change <literal>myOwnerUser</literal> and
<literal>myOwnerUserPassword</literal> appropriately for
your bot).

<question>
<para>
How do I make Supybot op my users?
</para>
</question>
<answer>
<para>
First, you'll have to make sure that your users register
with the bot. They can do this with the
<botcommand>register</botcommand> command. After they do
so, you'll want to add the
<capability>#channel,op</capability> capability to their
user. Use the <botcommand>channel
addcapability</botcommand> command to do this. After
that, your users should be able to use the
<botcommand>op</botcommand> command to get ops.
</para>
<para>
If you want your users to be auto-opped when they join the
channel, you'll need to load the <plugin>Enforcer</plugin>
plugin and turn its <registrygroup>autoOp</registrygroup>
configuration variable on. Use the
<botcommand>config</botcommand> command to do so. Here's
an example of how to do these steps:
</para>
<ircsession>
&lt;jemfinch|lambda&gt; I'm going to make an example session for giving
you auto-ops, for our FAQ.
&lt;dunk1&gt; ah ok ;]
&lt;jemfinch|lambda&gt; First, I need you to register with supybot, using
the "register" command (remember to send it in private).
&lt;dunk1&gt; done
&lt;jemfinch|lambda&gt; what name are you registered under?
&lt;dunk1&gt; dunk1
&lt;jemfinch|lambda&gt; ok, cool.
&lt;jemfinch|lambda&gt; @channel addcapability dunk1 op
&lt;supybot&gt; jemfinch|lambda: The operation succeeded.
&lt;jemfinch|lambda&gt; now use the "op" command to get ops.
&lt;dunk1&gt; @op
&mdash; supybot gives channel operator status to dunk1
&lt;dunk1&gt; works!
&lt;dunk1&gt; ;]
&lt;jemfinch|lambda&gt; @load Enforcer
&lt;supybot&gt; jemfinch|lambda: The operation succeeded.
&lt;jemfinch|lambda&gt; @config channel supybot.plugins.Enforcer.autoOp On
&lt;supybot&gt; jemfinch|lambda: The operation succeeded.
&lt;jemfinch|lambda&gt; ok, now cycle the channel (part and then rejoin)
&lt;&ndash; dunk1 (dunker@freebsd.nl) has left #supybot
&ndash;&gt; dunk1 (dunker@freebsd.nl) has joined #supybot
&mdash; supybot gives channel operator status to dunk1
&lt;jemfinch|lambda&gt; cool, thanks :)

<question>
<para>
Can users with the <capability>admin</capability>
capability change configuration variables?
</para>
</question>
<answer>
<para>
Currently, no. Since this is the first release of Supybot
that uses the registry, we wanted to stay on the
conservative side and require the
<capability>owner</capability> capability for changing all
non-channel-related configuration variables. Feel free to
make your case to us as to why a certain configuration
variable should only require the
<capability>admin</capability> capability instead of the
<capability>owner</capability> capability, and if we agree
with you, we'll change it for the next release.
</para>
</answer>
</qandaentry>
<qandaentry>
<question>
<para>
Can Supybot do factoids?
</para>
</question>
<answer>
<para>
Supybot most certainly can! In fact, we offer three
full-fledged factoids-related plugins!
</para>
<para>
<plugin>Factoids</plugin> (written by
<nick>jemfinch</nick>) is Supybot's original
factoids-related plugin. It offers full integration with
Supybot's nested commands as well as a complete 1:n key to
factoid ratio, with lookup by individual number. Factoids
also uses a channel-specific database instead of a global
database though that's configurable with the
<registrygroup>supybot.databases.plugins.channelSpecific</registrygroup>
configuration variable.
</para>
<para>
<plugin>MoobotFactoids</plugin> (written by
<nick>Strike</nick>) is much more full-featured, offering
users the ability to define factoids in a slightly more
user-friendly way, as well as parsing factoids to handle
&lt;reply&gt;, &lt;action&gt;, and alternations (defining
a factoid &ldquo;test&rdquo; as
&ldquo;&lt;reply&gt;(foo|bar|baz)&rdquo; will make the bot
send &ldquo;foo&rdquo; or &ldquo;bar&rdquo; or
&ldquo;baz&rdquo; to the channel (without the normal
&ldquo;test is &rdquo; at the beginning)). If you're
accustomed to Moobot's factoids or Blootbot's factoids,
then this is the Factoids plugin for you. Unfortunately,
due to the more natural definition syntax (required to be
comaptible with Moobot) you can't define Factoids with
nested commands; you'll have to evaluate the command first
and then copy the result into your factoid definition.
</para>

<para>
Can I import my Infobot/Blootbot/Moobot factoids into
Supybot?
</para>
</question>
<answer>
<para>
As of present, we have no automated way to do so.
<nick>Strike</nick> has written a few scripts for
importing a Moobot database into MoobotFactoids, however,
so you'll want to talk to him about helping you with that.
We're certainly happy to help you convert such databases;
if you can provide us with such a database exported to a
flat file, we can probably do the rest of the work to
write a script that imports it into a database for one of
our factoids-related plugins.

<question>
<para>
Do I really have to use separate databases for each
channel?
</para>
</question>
<answer>
<para>
Of course not! We default to separate databases for each
channel because, well, that's what <nick>jemfinch</nick>
always thought was reasonable. Anyway, if you change the
configuration variable
<registrygroup>supybot.databases.plugins.channelSpecific</registrygroup>
to <literal>False</literal> instead of
<literal>True</literal>, for <emphasis>most</emphasis>
databases, each channel will share the same database (the
exceptions are <plugin>ChannelStats</plugin>,
<plugin>Herald</plugin>, <plugin>Seen</plugin>, and
<plugin>WordStats</plugin>, which are inherently rather
channel-based).

<para>
<plugin>Karma</plugin> by default doesn't acknowledge
karma updates. If you check the karma of whatever you
increased/decreased, you'll note that your increment or

<question>
<para>
I added an alias, but it doesn't work!
</para>
</question>
<answer>
<para>
Take a look at <botcommand>help &lt;alias you
added&gt;</botcommand>. If the alias the bot has listed
doesn't match what you're giving it, chances re you need
to quote your alias in order for the brackets not to be
evaluated. For instance, if you're adding an alias to
give you a link to your homepage, you need to say:
<para>
<ircsession>
alias add mylink "format concat http://myhost.com/
[urlquote $1]"
</ircsession>
<para>
and not:
</para>
<ircsession>
alias add mylink format concat http://myhost.com/
[urlquote $1]
</ircsession>
<para>
The first version works; the second version will always
return the same url.

<qandaentry>
<question>
<para>
Is there a command that can tell me what capability
another command requires?
</para>
</question>
<answer>
<para>
No, there isn't, and there probably never will be.
Commands have the flexibility to check any capabilities
they wish to check; while this flexibility is useful, it
also makes it hard to guess what capability a certain
command requires. We could make a solution that would
work in a large majority of cases, but it wouldn't (and
couldn't!) be absolutely correct in all circumstances, and
since we're anal and we hate doing things halfway, we
probably won't ever add this partial solution.
</para>
<para>
Besides, is the error message so bad? If we did have such
a command, many users would call the command, see that
they could perform it, and then run the command, thus
doubling the activity in the channel. Is that something
you want?

</answer>
</qandaentry>
<qandaentry>
<question>
<para>
How do I make my Supybot connect to multiple servers?

Just use the <botcommand>connect</botcommand> command in

to submit your bug, then post it in the "Supybot Developer
Discussion" forum at our forums at
<ulink url="http://forums.supybot.org">

</para>
<para>
Anyway, when you submit your bug, we'll need several
things. If the bug involved an uncaught exception, we
need the traceback (basically the stuff from
&ldquo;Uncaught exception in &hellip;&rdquo; to the next
log entry). We'd also like to see the commands that
caused the bug, or happened around the time you saw the

<sect1>
<title>Introduction</title>
<para>
Ok, so you've decided to try out Supybot. That's great! The more
people who use Supybot, the more people can submit bugs and help
us to make it the best IRC bot in the world :)
</para>
<para>
First things first: Supybot <emphasis>requires</emphasis> Python
2.3. There ain't no getting around it. If you're a Python
developer, you probably know how superior 2.3 is to previous
incarnations. If you're not, just think about the difference
between a bowl of plain vanilla ice cream and a banana split. Or
something like that. Either way, <emphasis>we're</emphasis>
Python developers and we like banana splits.
</para>
</sect1>
<sect1>
<title>Installing the bot and its utilities</title>
<para>
So what do you do? First thing you'll want to do is run (with
root/admin privileges) <application>python setup.py
install</application>. This will install Supybot globally. If
you need to install locally for whatever reason, see this <ulink
url="http://tinyurl.com/2tb37">forum post</ulink> on how to do so.
You'll then have several new programs installed where Python
scripts are normally installed on your system
(<filename>/usr/bin</filename> or
<filename>/usr/local/bin</filename> are common on UNIX systems;
<filename>C:\Python23\Scripts</filename> is a common place on
Windows; and (watch out, this is a long one :))
<filename>/System/Library/Frameworks/Python.framework/Versions/2.3/bin</filename>
is a common place on MacOS X.). The two that might be of
particular interest to you, the new user, are
<script>supybot</script> and
<script>supybot-wizard</script> The former
(<script>supybot</script> is the script to run an actual
bot; the latter (<script>supybot-wizard</script> is an
in-depth wizard that provides a nice user interface for creating
configuration files for your bot. We'd prefer you to the use
<script>supybot-wizard</script>, but if you're in a
hurry or don't feel like being asked many questions, just run
supybot with no arguments and it'll ask you only the questions
necessary ")to run a bot.
</para>
</sect1>
<sect1>
<title>Firing up the bot for the first time</title>
<para>
So after running either of those two programs, you've got a nice
registry file handy. If you're not satisfied with your answers
to any of the questions you were asked, feel free to run the
program again until you're satisfied with all your answers. Once
you're satisfied, though, run the
<script>supybot</script> program with the
registry file you created as an argument. This will start the
bot; unless you turned off logging to stdout, you'll see some nice
log messages describing what the bot is doing at any particular
moment; it may pause for a significant amount of time after saying
"Connecting to ..." while the server tries to check its ident.
</para>
</sect1>
<sect1>
<title>Your first interactions with the bot</title>
<para>
Ok, so let's assume your bot connected to the server fine and
joined the channels you told it to join. For now we'll assume you
named your bot <nick>supybot</nick> (you probably didn't,
but it'll make it much clearer in the examples that follow to
assume that you did). We'll also assume that you told it to join
<channel>#channel</channel> (a nice generic name for a channel,
isn't it? :)) So what do you do with this bot that you just made
to join your channel? Try this in the channel:
</para>
<ircsession>
supybot: list
</ircsession>
<para>
Replacing <nick>supybot</nick> with the actual name you
picked for your bot, of course. Your bot should reply with a list
of the plugins he currently has loaded. At least
<plugin>Admin</plugin>, <plugin>Channel</plugin>,
<plugin>Config</plugin>, <plugin>Misc</plugin>,
<plugin>Owner</plugin>, and <plugin>User</plugin> should be
there; if you used <script>supybot-wizard</script> to
create your configuration file you may have many more plugins
loaded. The <botcommand>list</botcommand> command can also be used to
list the commands in a given plugin:
</para>
<ircsession>
supybot: list Misc
</ircsession>
<para>
Will list all the commands in the <plugin>Misc</plugin> plugin.
</para>
<sect2>
<title>Accessing the bot's online help</title>
<para>
If you want to see the help for any command, just use
the <botcommand>help</botcommand> command:
</para>
<ircsession>
supybot: help help
supybot: help list
supybot: help load
</ircsession>
</sect2>
<sect2>
<title>Dealing with ambiguous commands</title>
<para>
Sometimes more than one plugin will have a given command; for
instance, the <botcommand>list</botcommand> command exists in both
the <plugin>Misc</plugin> and <plugin>Config</plugin>
plugins (both loaded by default). <plugin>List</plugin>, in
this case, defaults to the <plugin>Misc</plugin> plugin, but
you may want to get the help for the
<botcommand>list</botcommand>
command in the <plugin>Config</plugin> plugin. In that
case, you'll want to give your command like this:
</para>
<ircsession>
supybot: help config list
</ircsession>
<para>
Anytime your bot tells you that a given command is defined in
several plugins, you'll want to use this syntax
(<botcommand>plugin command</botcommand>) to disambiguate which
plugin's command you wish to call. For instance, if you
wanted to call the <plugin>Config</plugin> plugin's
<botcommand>list</botcommand> command, then you'd need to say:
</para>
<ircsession>
supybot: config list
</ircsession>
<para>
Rather than just <botcommand>list</botcommand>.
</para>
</sect2>
<sect2>
<title>Loading plugins</title>
<para>
Now that you know how to deal with plugins having commands
with the same name, let's take a look at loading other
plugins. If you didn't use
<script>supybot-wizard</script>, though, you might
do well to try it before playing around with loading plugins
yourself: each plugin has its own
<function>configure</function> function that the wizard uses
to setup the appropriate registry entries if the plugin
requires any.
</para>
<sect3>
<title>Identifying yourself as the bot owner</title>
<para>
Now, if you do want to play around with loading plugins,
you're going to need to have the
<capability>owner</capability>
capability. If you ran the wizard, then chances are you
already added an owner user for yourself. If not,
however, you can add one via the handy-dandy
<script>supybot-adduser</script> script. You'll
want to run it while the bot is not running (otherwise it
could overwrite
<script>supybot-adduser</script>'s changes to
your user database before you get a chance to reload
them). Just follow the prompts, and when it asks if you
want to give the user any capabilities, say yes and then
give yourself the <capability>owner</capability> capability
(without the quotes), restart the bot and you'll be ready
to load some plugins!
</para>
<para>
Now, in order for the bot to recognize you as your owner
user, you'll have to identify with the bot. Open up a
query window in your irc client (/query should do it; if
not, just know that you can't identify in a channel
because it requires sending your password to the bot).
Then type this:
</para>
<ircsession>
help identify
</ircsession>
<para>
And follow the instructions; the command you send will
probably look like this, with your owner user and password
replaced:
</para>
<ircsession>
identify myowneruser myuserpassword
</ircsession>
<para>
The bot will tell you that &ldquo;The operation
succeeded&rdquo; if you got the right name and password.
Now that you're identified, you can do anything that
requires any privilege: that includes all the commands in
the <plugin>Owner</plugin> and <plugin>Admin</plugin>
plugins, which you may want to take a look at (using the
<botcommand>list</botcommand> and
<botcommand>help</botcommand>
commands, of course). One command in particular that you
might want to use (it's from the <plugin>User</plugin>
plugin) is the <botcommand>addhostmask</botcommand> command: it
lets you add a hostmask to your user record so the bot
recognizes you by your hostmask instead of requiring you
to always identify with it before it recognizes you. Use
the <botcommand>help</botcommand> command to see how this
command works. Here's how I often use it:
</para>
<ircsession>
addhostmask myuser [hostmask] mypassword
</ircsession>
<para>
You may not have seen that "[hostmask]" syntax before.
Supybot allows nested commands, which means that any
command's output can be nested as an argument to another
command. The hostmask command from the
<plugin>Misc</plugin> plugin returns the hostmask of a
given nick, but if given no arguments, it returns the
hostmask of the person giving the command. So the command
above adds the hostmask I'm currently using to my user's
list of recognized hostmasks. I'm only required to give
<literal>mypassword</literal> if I'm not already
identified with the bot.
</para>
</sect3>
</sect2>
<sect2>
<title>The <botcommand>more</botcommand> command</title>
<para>
Another command you might find yourself needing somewhat often
is the <botcommand>more</botcommand> command. The IRC protocol
limits messages to 512 bytes, 60 or so of which must be
devoted to some bookkeeping. Sometimes, however, Supybot
wants to send a message that's longer than that. What it
does, then, is break it into "chunks" and send the first one,
following it with "(X more messages)" where X is how many more
chunks there are. To get to these chunks, use the more
command. One way to try is to look at the listing of
configuration groups for the bot (more on this in the
CONFIGURATION document) by giving the command "config list
supybot". Last I checked, it'll overflow into a second chunk.
When you invoke this command, you should see output like:
</para>
<ircsession>
&lt;supybot&gt; nick, ident, user, server, password, channels, prefixChars,
defaultCapabilities, defaultAllow, defaultIgnore,
humanTimestampFormat, externalIP, bracketSyntax, pipeSyntax,
followIdentificationThroughNickChanges, alwaysJoinOnInvite,
showSimpleSyntax, maxHistoryLength, nickmods, throttleTime,
snarfThrottle, threadAllCommands, pingServer, pingInterval,
upkeepInterval, flush, (1 more message)
</ircsession>
<para>
Now, to see the rest of the output, simply give the command
<botcommand>more</botcommand>, and it will show you the rest:
</para>
<ircsession>
&lt;jemfinch&gt; more
&lt;supybot&gt; httpPeekSize, and defaultSocketTimeout
</ircsession>
</sect2>
</sect1>
<sect1>
<title>You're ready!</title>
<para>
You should now have a solid foundation for using Supybot. Be sure
to check the help that is built-in to the bot itself if you have
any questions, and enjoy using Supybot!

<para>
These are the interfaces for some of the objects you'll deal with
if you code for Supybot.
</para>
<sect2>
<title><classname>ircmsgs.IrcMsg</classname>
<para>
This is the object that represents an IRC message. It has
several methods and attributes. The most important thing
about this class, however, is that it <emphasis>is</emphasis>
hashable, and thus <emphasis>cannot</emphasis> be modified.
Do not change any attributes; any code that modifies an IRC
message is <emphasis>broken</emphasis> and should not exist.
</para>
<variablelist>
<title>Interesting methods</title>
<varlistentry>
<term>__init__</term>
<listitem>
<para>
One of the more complex initializers in a class.
It can be used in three different ways:
</para>
<orderedlist numeration="arabic" spacing="normal">
<listitem>
<para>
It can be given a string, as one received
from the server, which it will then parse
into its separate components and
instantiate the class with those
components as attributes.
</para>
</listitem>
<listitem>
<para>
It can be given a command, some (optional)
arguments, and a (optional) prefix, and
will instantiate the class with those
components as attributes.
</para>
</listitem>
<listitem>
<para>
It can be given, in addition to any of the
above arguments, a <varname>msg</varname>
keyword argument that will use the
attributes of msg as defaults. This
exists to make it easier to copy messages,
since the class is immutable.
</para>
</listitem>
</orderedlist>
</listitem>
</varlistentry>
<varlistentry>
<term>__str__</term>
<listitem>
<para>
This returns the message in a string form suitable
for sending to a server.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>__repr__</term>
<listitem>
<para>
This returns the message in a form suitable for
<function>eval()</function>, assuming the name
<varname>IrcMsg</varname> is in your namespace and
is bound to this class.
</para>
</listitem>
</varlistentry>
</variablelist>
<para>
The following attributes are the meat of this class. These
are generally what you'll be looking at with
<varname>IrcMsg</varname>s.
</para>
<variablelist>
<title>Interesting attributes</title>
<varlistentry>
<term>command</term>
<listitem>
<para>
This is the command of the
<varname>IrcMsg</varname> &ndash;
<literal>PRIVMSG</literal>,
<literal>NOTICE</literal>,
<literal>WHOIS</literal>,
etc.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>args</term>
<listitem>
<para>
This is a tuple of the arguments to the
<varname>IrcMsg</varname>. Some messages have
arguments, some don't, depending on what command
they are. You are, of course, always assured that
<varname>args</varname> exists and is a tuple,
though it might be empty.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>prefix</term>
<listitem>
<para>
This is the hostmask of the person/server the
message is from. In general, you won't be setting
this on your outgoing messages, but incoming
messages will always have one. This is the whole
hostmask; if the message was received from a
server, it'll be the server's hostmask; if the
message was received from a user, it'll be the
whole user hostmask. In that case, however, it's
also parsed out into the
<varname>nick</varname>/<varname>user</varname>/<varname>host</varname>
attributes, which are probably more useful to
check for many purposes.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>nick</term>
<listitem>
<para>
If the message was sent by a user, this will be
the nick of the user. If it was sent by a server,
this will be the server's name (something like
<literal>calvino.freenode.net</literal> or
similar).
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>user</term>
<listitem>
<para>
If the message was sent by a user, this will be
the user string of the user &ndash; what they put
into their IRC client for their "full name." If
it was sent by a server, it'll be the server's
name, again.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>host</term>
<listitem>
<para>
If the message was sent by a user, this will be
the host portion of their hostmask. If it was
sent by a server, it'll be the server's name (yet
again :))
</para>
</listitem>
</varlistentry>
</variablelist>
</sect2>
<sect2>
<title><classname>irclib.Irc</classname>
<para>
This is the object to handle everything about IRC except the
actual connection to the server itself.
(<emphasis>NOTE</emphasis> that the object actually received
by commands in subclasses of
<classname>callbacks.Privmsg</classname> is an
<classname>IrcObjectProxy</classname>, which is described
later. It augments the following interface with several
methods of its own to help plugin authors.)
</para>
<variablelist>
<title>Interesting methods</title>
<varlistentry>
<term>queueMsg</term>
<listitem>
<para>
Queues a message for sending to the server. The
queue is generally FIFO, but it does prioritize
messages based on their command.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>sendMsg</term>
<listitem>
<para>
Queues a message for sending to the server prior
to any messages in the normal queue. This is
exactly a FIFO queue, no reordering is done at
all.
</para>
</listitem>
</varlistentry>
<!--<note>
<para>
The following two methods are the most important for
people writing new <varname>IrcDriver</varname>s.
Otherwise, you really don't need to pay attention to
them.
</para>

<varlistentry>
<term>takeMsg</term>

<title>Introduction</title>
<para>
Ok, so you want to write a callback for supybot. Good, then this
is the place to be. We're going to start from the top (the
highest level, where supybot code does the most work for you) and
move lower after that.
</para>
<para>
So have you used supybot? If not, you need to go use it, get a
feel for it, see how the various commands work and such.
</para>
<para>
So now that we know you've used supybot, we'll start getting into
details.
</para>
</sect1>
<sect1>
<title>Creating your own plugin</title>
<sect2>
<title>
Using <script>scripts/newplugin.py</script>
</title>
<para>
First, the easiest way to start writing a module is to use the
wizard provided, <script>scripts/newplugin.py</script>.
Here's an example session:
</para>
<screen>
functor% scripts/newplugin.py
What should the name of the plugin be? Random
Supybot offers two major types of plugins: command-based and regexp-
based. Command-based plugins are the kind of plugins you've seen most
when you've used supybot. They're also the most featureful and
easiest to write. Commands can be nested, for instance, whereas
regexp-based callbacks can't do nesting. That doesn't mean that
you'll never want regexp-based callbacks. They offer a flexibility
that command-based callbacks don't offer; however, they don't tie into
the whole system as well. If you need to combine a command-based
callback with some regexp-based methods, you can do so by subclassing
callbacks.PrivmsgCommandAndRegexp and then adding a class-level
attribute "regexps" that is a sets.Set of methods that are regexp-
based. But you'll have to do that yourself after this wizard is
finished :)
Do you want a command-based plugin or a regexp-based plugin? [command/
regexp] command
Sometimes you'll want a callback to be threaded. If its methods
(command or regexp-based, either one) will take a signficant amount
of time to run, you'll want to thread them so they don't block
the entire bot.
Does your plugin need to be threaded? [y/n] n
Your new plugin template is in plugins/Random.py
functor%
</screen>
<para>
So that's what it looks like. Now let's look at the source
code (if you'd like to look at it in your programming editor,
the whole plugin is available as
<filename>examples/Random.py</filename>):

<title>Customizing the boilerplate code</title>
<para>
So a few notes, before we customize it.
</para>
<para>
You'll probably want to change the copyright notice to be your
name. It wouldn't stick even if you kept my name, so you
might as well :)
</para>
<para>
Describe what you want the plugin to do in the docstring.
This is used in <script>scripts/setup.py</script> in
order to explain to the user the purpose of the module. It's
also returned when someone asks the bot for help for a given
module (instead of help for a certain command). We'll change
this one to <literal>"Lots of stuff relating to random
numbers."</literal>
</para>
<para>
Then there are the imports. The
<module>callbacks</module>
module is used (the class you're given subclasses
<classname>callbacks.Privmsg</classname>) but the
<module>privmsgs</module> module isn't used. That's
alright; we can almost guarantee you'll use it, so we go ahead
and add the import to the template.
</para>
<para>
Then you see a <function>configure</function> function. This
the function that's called when users decide to add your
module in <script>scripts/setup.py</script>. You'll
note that by default it simply registers the plugin to be
automatically loaded on startup. For many
plugins this is all you need; for more complex plugins, you
might need to ask questions and add commands based on the
answers.
</para>
</sect2>
<sect2>
<title>Digging in: customizing the plugin class</title>
<para>
Now comes the meat of the plugin: the plugin class.
</para>
<para>
What you're given is a skeleton: a simple subclass of
<classname>callbacks.Privmsg</classname> for you to start
with. Now let's add a command.
</para>
<para>
I don't know what you know about random number generators, but
the short of it is that they start at a certain number (a
seed) and they continue (via some somewhat
complicated/unpredictable algorithm) from there. This seed
(and the rest of the sequence, really) is all nice and
packaged up in Python's <module>random</module> module, the
<varname>Random</varname> object. So the first thing we're
going to have to do is give our plugin a
<varname>Random</varname> object.
</para>
<para>
Normally, when we want to give instances of a class an object,
we'll do so in the <function>__init__</function> method. And
that works great for plugins, too. The one thing you have to
be careful of is that you call the superclass
<function>__init__</function> method at the end of your own
<function>__init__</function>. So to add this
<classname>random.Random</classname> object to our plugin, we
can replace the <keyword>pass</keyword> statement with
this:
</para>
<programlisting>
def __init__(self):
self.rng = random.Random()
callbacks.Privmsg.__init__(self)
</programlisting>
<para>
(<varname>rng</varname>is an abbreviation for "random number
generator," in case you were curious)
</para>
<para>
Do be careful not to give your <function>__init__</function>
any arguments (other than <varname>self</varname>, of course).
There's no way anything will ever get to them! If you have
some sort of initial values you need to get to your plugin
before it can do anything interesting, you should get those
values from the registry.
</para>
<para>
There's an easier way to get our plugin to have its own rng
than to define an <function>__init__</function>. Plugins are
unique among classes because we're always certain that there
will only be one instance -- supybot doesn't allow us to load
multiple instances of a single plugin. So instead of adding
the rng in <function>__init__</function>, we can just add it
as a attribute to the class itself. Like so (replacing the
<function>pass</function> statement again):
</para>
<programlisting>
rng = random.Random()
</programlisting>
<para>
And we save two lines of code and make our code a little more
clear :)
</para>
<para>
Now that we have an RNG, we need some way to get random
numbers. So first, we'll add a command that simply gets the
next random number and gives it back to the user. It takes no
arguments, of course (what would you give it?). Here's the
command, and I'll follow that with the explanation of what
each part means.
</para>
<programlisting>
def random(self, irc, msg, args):
"""takes no arguments
Returns the next random number generated by the random number
generator.
"""
irc.reply(str(self.rng.random()))
</programlisting>
<para>
And that's it! Pretty simple, huh? Anyway, you're probably
wondering what all that <emphasis>means</emphasis>. We'll
start with the <keyword>def</keyword> statement:
</para>
<programlisting>
def random(self, irc, msg, args):
</programlisting>
<para>
What that does is define a command
<botcommand>random</botcommand>. You can call it by saying
"@random" (or whatever prefix character your specific bot
uses). The arguments are a bit less obvious.
<varname>self</varname> is self-evident (hah!).
<varname>irc</varname> is the <classname>Irc</classname>
object passed to the command; <varname>msg</varname> is the
original <classname>IrcMsg</classname> object. But you're
really not going to have to deal with either of these too much
(with the exception of calling <function>irc.reply</function>
or <function>irc.error</function>). What you're
<emphasis>really</emphasis> interested in is the
<varname>args</varname> arg. That is a list of all the
arguments passed to your command, pre-parsed and already
evaluated (i.e., you never have to worry about nested
commands, or handling double quoted strings, or splitting on
whitespace &ndash; the work has already been done for you).
You can read about the <classname>Irc</classname> object in
<filename>irclib.py</filename> (you won't find
<function>.reply</function> or <function>.error</function>
there, though, because you're actually getting an
<classname>IrcObjectProxy</classname>, but that's beyond the
level we want to describe here :)). You can read about the
<varname>msg</varname> object in
<filename>ircmsgs.py</filename>. But again, you'll very
rarely be using these objects.
</para>
<para>
(In case you're curious, the answer is yes, you
<emphasis>must</emphasis> name your arguments <varname>(self,
irc, msg, args)</varname>. The names of those arguments is
one of the ways that supybot uses to determine which methods
in a plugin class are commands and which aren't. And while
we're talking about naming restrictions, all your commands
should be named in all-lowercase with no underscores. Before
calling a command, supybot always converts the command name to
lowercase and removes all dashes and underscores. On the
other hand, you now know an easy way to make sure a method is
never called (even if its arguments are <varname>(self, irc,
msg, args)</varname>, however unlikely that may be). Just
name it with an underscore or an uppercase letter in it :))
</para>
<para>
You'll also note that the docstring is odd. The wonderful
thing about the supybot framework is that it's easy to write
complete commands with help and everything: the docstring
<emphasis>is</emphasis> the help! Given the above docstring,
this is what a supybot does:
</para>
<ircsession>
&lt;jemfinch&gt; @help random
&lt;angryman&gt; jemfinch: (random takes no arguments) -- Returns the
next random number from the random number generator.
</ircsession>
<para>
Now on to the actual body of the function:
</para>
<programlisting>
irc.reply(msg, str(self.rng.random()))
</programlisting>
<para>
<function>irc.reply</function> simply takes one simple
argument: a string The string is the reply to be sent. Don't
worry about length restrictions or anything
&ndash; if the string you want to send is too big for an IRC
message (and oftentimes that turns out to be the case :)) the
Supybot framework handles that entirely transparently to you.
Do make sure, however, that you give
<function>irc.reply</function> a string. It doesn't take
anything else (sometimes even unicode fails!). That's why we
have "str(self.rng.random())" instead of simply
"self.rng.random()" &ndash; we had to give
<function>irc.reply</function> a string.
</para>
<para>
Anyway, now that we have an RNG, we have a need for seed! Of
course, Python gives us a good seed already (it uses the
current time as a seed if we don't give it one) but users
might want to be able to repeat "random" sequences, so letting
them set the seed is a good thing. So we'll add a seed
command to give the RNG a specific seed:
</para>
<programlisting>
def seed(self, irc, msg, args):
"""&lt;seed&gt;
Sets the seed of the random number generator. &lt;seed&gt; must be
an int or a long.
"""
seed = privmsgs.getArgs(args)
try:
seed = long(seed)
except ValueError:
# It wasn't a valid long!
irc.error(msg, '&lt;seed&gt; must be a valid int or long.')
return
self.rng.seed(seed)
irc.replySuccess()
</programlisting>
<para>
So this one's a bit more complicated. But it's still pretty
simple. The method name is <botcommand>seed</botcommand> so
that'll be the command name. The arguments are the same, the
docstring is of the same form, so we don't need to go over
that again. The body of the function, however, is
significantly different.
</para>
<para>
<function>privmsgs.getArgs</function> is a function you're
going to be seeing a lot of when you write plugins for
supybot. What it does is basically give you the right number
of arguments for your comamnd. In this case, we want one
argument. But we might have been given any number of
arguments by the user. So
<function>privmsgs.getArgs</function> joins them
appropriately, leaving us with one single "seed" argument (by
default, it returns one argument as a single value; more
arguments are returned in a tuple/list). Yes, we could've
just said "seed = args[0]" and gotten the first argument, but
what if the user didn't pass us an argument at all? Then
we've got to catch the <classname>IndexError</classname> from
<varname>args[0]</varname> and complain to the user about it.
<function>privmsgs.getArgs</function>, on the other hand,
handles all that for us. If the user didn't give us enough
arguments, it'll reply with the help string for the command,
thus saving us the effort.
</para>
<para>
So we have the seed from
<function>privmsgs.getArgs</function>. But it's a string.
The next three lines is pretty darn obvious: we're just
converting the string to a int of some sort. But if it's not,
that's when we're going to call
<function>irc.error</function>. It has the same interface as
we saw before in <function>irc.reply</function>, but it makes
sure to remind the user that an error has been encountered
(currently, that means it puts <literal>"Error: "</literal> at
the beginning of the message). After erroring, we return.
It's important to remember this <keyword>return</keyword>
here; otherwise, we'll just keep going down through the
function and try to use this <varname>seed</varname> variable
that never got assigned. A good general rule of thumb is that
any time you use <function>irc.error</function>, you'll want
to return immediately afterwards.
</para>
<para>
Then we set the seed &ndash; that's a simple function on our
rng object. Assuming that succeeds (and doesn't raise an
exception, which it shouldn't, because we already read the
documentation and know that it should work) we reply to say
that everything worked fine. That's what
<function>irc.replySuccess</function> says. By default, it
has the very dry (and appropriately robot-like) "The operation
succeeded." but you're perfectly welcome to customize it
yourself &ndash; the registry was written to be modified!
</para>
<para>
So that's a bit more complicated command. But we still
haven't dealt with multiple arguments. Let's do that
next.
</para>
<para>
So these random numbers are useful, but they're not the kind
of random numbers we usually want in Real Life. In Real Life,
we like to tell someone to "pick a number between 1 and 10."
So let's write a function that does that. Of course, we won't
hardcode the 1 or the 10 into the function, but we'll take
them as arguments. First the function:
</para>
<programlisting>
def range(self, irc, msg, args):
"""&lt;start&gt; &lt;end&gt;
Returns a number between &lt;start&gt; and &lt;end&gt;, inclusive (i.e., the number
can be either of the endpoints.
"""
(start, end) = privmsgs.getArgs(args, required=2)
try:
end = int(end)
start = int(start)
except ValueError:
irc.error(msg, '&lt;start&gt; and &lt;end&gt; must both be integers.')
return
# .randrange() doesn't include the endpoint, so we use end+1.
irc.reply(msg, str(self.rng.randrange(start, end+1)))
</programlisting>
<para>
Pretty simple. This is becoming old hat by now. The only new
thing here is the call to
<function>privmsgs.getArgs</function>. We have to make sure,
since we want two values, to pass a keyword parameter
"required" into <function>privmsgs.getArgs</function>. Of
course, <function>privmsgs.getArgs</function> handles all the
checking for missing arguments and whatnot so we don't have
to.
</para>
<para>
The <classname>Random</classname> object we're using offers us
a "sample" method that takes a sequence and a number (we'll
call it <varname>N</varname>) and returns a list of
<varname>N</varname> items taken randomly from the sequence.
So I'll show you an example that takes advantage of multiple
arguments but doesn't use
<function>privmsgs.getArgs</function> (and thus has to handle
its own errors if the number of arguments isn't right).
Here's the code:
</para>
<programlisting>
def sample(self, irc, msg, args):
"""&lt;number of items&gt; [&lt;text&gt; ...]

<para>
Most everything here is familiar. The difference between this
and the previous examples is that we're dealing with
<varname>args</varname> directly, rather than through
<function>getArgs</function>. Since we already have the
arguments in a list, it doesn't make any sense to have
<function>privmsgs.getArgs</function> smush them all together
into a big long string that we'll just have to re-split. But
we still want the nice error handling of
<function>privmsgs.getArgs</function>. So what do we do? We
raise <classname>callbacks.ArgumentError</classname>! That's
the secret juju that <function>privmsgs.getArgs</function> is
doing; now we're just doing it ourself. Someone up our
callchain knows how to handle it so a neat error message is
returned. So in this function, if
<function>.pop(0)</function> fails, we weren't given enough
arguments and thus need to tell the user how to call us.
</para>
<para>
So we have the args, we have the number, we do a simple call
to <function>random.sample</function> and then we do this
funky <function>utils.commaAndify</function> to it. Yeah, so
I was running low on useful names :) Anyway, what it does is
take a list of strings and return a string with them joined by
a comma, the last one being joined with a comma and "and". So
the list ['foo', 'bar', 'baz'] becomes "foo, bar, and baz".
It's pretty useful for showing the user lists in a useful
form. We map the strings with <function>repr()</function>
first just to surround them with quotes.
</para>
<para>
So we have one more example. Yes, I hear your groans, but
it's pedagogically useful :) This time we're going to write a
command that makes the bot roll a die. It'll take one
argument (the number of sides on the die) and will respond
with the equivalent of "/me rolls a __" where __ is the number
the bot rolled. So here's the code:
</para>
<programlisting>
def diceroll(self, irc, msg, args):
"""[&lt;number of sides&gt;]
Rolls a die with &lt;number of sides&gt; sides. The default number
of sides is 6.
"""
try:
n = privmsgs.getArgs(args, required=0, optional=1)
if not n:
n = 6
n = int(n)
except ValueError:
irc.error(msg, 'Dice have integer numbers of sides. Use one.')
return
s = 'rolls a %s' % self.rng.randrange(1, n+1)
irc.reply(s, action=True)
</programlisting>
<para>
There's a lot of stuff you haven't seen before in there. The
most important, though, is the first thing you'll notice
that's different: the <function>privmsg.getArgs</function>
call. Here we're offering a default argument in case the user
is too lazy to supply one (or just wants a nice, standard
six-sided die :)) <function>privmsgs.getArgs</function>
supports that; we'll just tell it that we don't
<emphasis>need</emphasis> any arguments (via
<varname>required=0</varname>) and that we <emphasis>might
like</emphasis> one argument (<varname>optional=1</varname>).
If the user provides an argument, we'll get it -- if they
don't, we'll just get an empty string. Hence the "if not n: n
= 6", where we provide the default.
</para>
<para>
You'll also note that <function>irc.reply</function> was given
a keyword argument here, <varname>action</varname>. This
means that the reply is to be made as an action rather than a
normal reply.
</para>
<para>
So that's our plugin. 5 commands, each building in
complexity. You should now be able to write most anything you
want to do in Supybot. Except regexp-based plugins, but
that's a story for another day (and those aren't nearly as
cool as these command-based callbacks anyway :)). Now we need
to flesh it out to make it a full-fledged plugin.

Q: Why does my bot not recognize me or tell me that I don't have the
"owner" capability?
A: Because you've not given it anything to recognize you from!
You'll need to identify with the bot ("help identify" to see how
that works) or add your hostmask to your user record ("help
addhostmask" to see how that works) for it to know that you're you.
You may wish to note that addhostmask can accept a password; rather
than identify, you can send the command "addhostmask myOwnerUser
[hostmask] myOwnerUserPassword" and the bot will add your current
hostmask to your owner user (of course, you should change
myOwnerUser and myOwnerUserPassword appropriately for your bot).
Q: What's a hostmask?
A: Each user on IRC is uniquely identified by a string which we call
a "hostmask." The IRC RFC refers to it as a prefix. Either way,
it consists of a nick, a user, and a host, in the form
nick!user@host. If your Supybot complains that something you've
given to it isn't a hostmask, make sure that you have those three
components and that they're joined in the appropriate manner.
Q: How do I make my Supybot op my users?
A: First, you'll have to make sure that your users register with the
bot. They can do this with the "register" command. After they do
so, you'll want to add the #channel,op capability to their user.
Use the "channel addcapability" command to do this. After that,
your users should be able to use the "op" command to get ops.
If you want your users to be auto-opped when they join the channel,
you'll need to load the Enforcer plugin and turn its autoOp
configuration variable on. Use the "config" command to do so.
Here's an example of how to do these steps:
<jemfinch> I'm going to make an example session for giving
you auto-ops, for our FAQ.
<dunk1> ah ok ;]
<jemfinch> First, I need you to register with supybot, using
the "register" command (remember to send it in
private).
<dunk1> done
<jemfinch> what name are you registered under?
<dunk1> dunk1
<jemfinch> ok, cool.
<jemfinch> @channel addcapability dunk1 op
<supybot> jemfinch: The operation succeeded.
<jemfinch> now use the "op" command to get ops.
<dunk1> @op
--- supybot gives channel operator status to dunk1
<dunk1> works!
<dunk1> ;]
<jemfinch> @load Enforcer
<supybot> jemfinch: The operation succeeded.
<jemfinch> @config channel supybot.plugins.Enforcer.autoOp On
<supybot> jemfinch: The operation succeeded.
<jemfinch> ok, now cycle the channel (part and then rejoin)
<-- dunk1 (dunker@freebsd.nl) has left #supybot
--> dunk1 (dunker@freebsd.nl) has joined #supybot
--- supybot gives channel operator status to dunk1
<jemfinch> cool, thanks :)
Q: Can users with the "admin" capability change configuration
variables?
A: Currently, no. Feel free to make your case to us as to why a
certain configuration variable should only require the "admin"
capability instead of the "owner" capability, and if we agree
with you, we'll change it for the next release.
Q: Can Supybot do factoids?
A: Supybot most certainly can! In fact, we offer three full-fledged
factoids-related plugins!
Factoids (written by jemfinch) is Supybot's original
factoids-related plugin. It offers full integration with Supybot's
nested commands as well as a complete 1:n key to factoid ratio,
with lookup by individual number. Factoids also uses a
channel-specific database instead of a global database, though
that's configurable with the
supybot.databases.plugins.channelSpecific configuration variable.
MoobotFactoids (written by Strike) is much more full-featured,
offering users the ability to define factoids in a slightly more
user-friendly way, as well as parsing factoids to handle <reply>,
<action>, and alternations (defining a factoid "test" as
"<reply>(foo|bar|baz)" will make the bot send "foo" or "bar" or
"baz" to the channel (without the normal "test is " at the
beginning)). If you're accustomed to Moobot's factoids or
Blootbot's factoids, then this is the Factoids plugin for you.
Unfortunately, due to the more natural definition syntax (required
to be compatible with Moobot) you can't define Factoids with nested
commands; you'll have to evaluate the command first and then copy
the result into your factoid definition.
Infobot (written by jamessan) is used for Infobot compatibility;
if you still want the basic functionality of Infobot, this is the
plugin to use.
Q: Can I import my Infobot/Blootbot/Moobot factoids into Supybot?
A: As of present, we have no automated way to do so. Strike has
written a few scripts for importing a Moobot database into
MoobotFactoids, however, so you'll want to talk to him about
helping you with that. We're certainly happy to help you convert
such databases; if you can provide us with such a database exported
to a flat file, we can probably do the rest of the work to write a
script that imports it into a database for one of our
factoids-related plugins.
Q: Do I really have to use separate databases for each channel?
A: Of course not! We default to separate databases for each channel
because, well, that's what jemfinch always thought was
reasonable. Anyway, if you change the configuration variable
supybot.databases.plugins.channelSpecific to False instead of
True, for *most* databases, each channel will share the same
database (the exceptions are ChannelStats, Herald, Seen, and
WordStats, which are inherently rather channel-based).
Q: Karma doesn't seem to work for me.
A: Karma by default doesn't acknowledge karma updates. If you check
the karma of whatever you increased/decreased, you'll note that
your increment or decrement still took place. If you'd rather
Karma acknowledge karma updates, change the
supybot.plugins.Karma.response configuration variable to On.
Q: I added an alias, but it doesn't work!
A: Take a look at "help <alias you added>". If the alias the bot has
listed doesn't match what you're giving it, chances are you need
to quote your alias in order for the brackets not to be
evaluated. For instance, if you're adding an alias to give you a
link to your homepage, you need to say:
alias add mylink "format concat http://my.host.com/ [urlquote $1]"
and not:
alias add mylink format concat http://my.host.com/ [urlquote $1]
The first version works; the second version will always return the
same url.
Q: Is there a command that can tell me what capability another
command requires?
A: No, there isn't, and there probably never will be. Commands have
the flexibility to check any capabilities they wish to check;
while this flexibility is useful, it also makes it hard to guess
what capability a certain command requires. We could make a
solution that would work in a large majority of cases, but it
wouldn't (and couldn't!) be absolutely correct in all
circumstances, and since we're anal and we hate doing things
halfway, we probably won't ever add this partial solution.
Besides, is the error message so bad? If we did have such a
command, many users would call the command, see that they could
perform it, and then run the command, thus doubling the activity
in the channel. Is that something you want?
Q: How do I make my Supybot connect to multiple servers?
A: Just use the "connect" command in the Network plugin. Easy as pie!
Q: My bot can't handle nicks with brackets in them! It always
complains about something not being a valid command, or about
spurious or missing right brackets, etc.
A: You should quote arguments (using double quotes, like this:
"foo[bar]") that have brackets in them that you don't wish to be
evaluated as nested commands. Otherwise, you can turn off nested
commands by setting supybot.commands.nested to False, or change
the brackets that nest commands, by setting
supybot.commands.nested.brackets to some other value (like <>,
which can't occur in IRC nicks).
Q: I've edited my configuration file, but my Supybot doesn't notice
the changes! Even if I restart it, it doesn't see them. What's
the deal?
A: Supybot won't reload its configuration files unless you tell it
to. In addition, when Supybot exits (and periodically while it
runs) it flushes its configuration file to disk. The safest way
to avoid problems with configuration file edits is simply to exit
the bot before editing the configuration file(s). If you don't
wish to do that, however, you can edit the file, save the changes,
and tell the bot to reload its configuration, either via the
reload command in the Config plugin, or by sending the bot a
SIGHUP. There is a brief period in this whole sequence where the
bot can flush its configuration to disk after you write your
changes, but we even have something to fix that: set the
configuration variable supybot.flush to False, and then reload the
configuration.
Q: I found a bug, what do I do?
A: Submit it on Sourceforge through our Sourceforge project page:
<http://sourceforge.net/tracker/?group_id=58965&atid=489447>. If
Sourceforge happens to be down when you try to submit your bug,
then post it in the "Supybot Developer Discussion" forum at our
forums at <http://forums.supybot.org/>. If that doesn't work,
email supybot-bugs@lists.sourceforge.net. If that doesn't work,
email jemfinch@supybot.org. If that doesn't work, find yourself
some carrier pigeons and ... hah! You thought I was serious!
Anyway, when you submit your bug, we'll need several things. If
the bug involved an uncaught exception, we need the traceback
(basically the stuff from "Uncaught exception in ..." to the next
log entry). We'd also like to see the commands that caused the
bug, or happened around the time you saw the bug. If the bug
involved a database, we'd love to see the database. Remember, it's
always worse to send us too little information in a bug report than
too much.
Q: Is there a way just to load *all* the plugins Supybot has?
A: No, there isn't. Even if there were, some plugins conflict with
other plugins, so it wouldn't make much sense to load them. For
instance, what would a bot do with Factoids, MoobotFactoids, and
Infobot all loaded? Probably just annoy people :)
If you want to know more about the plugins that are available,

These are a list of recurrent bugs in Supybot, and ways to notice
them. It just might come in useful for people maintaining code.
1. Using == or != when you mean ircutils.strEqual. Nicks, prefixes,
and channels should be compared for equality not by == or !=, but
by ircutils.strEqual. This does a case-normalized check. Don't
just use lower() because that doesn't use the rfc1459 casemapping.
To find:
grep == plugins/*.py | egrep "nick|channel"
grep "!=" plugins/*.py | egrep "nick|channel"
2. Using a warning log when it really should be an info log. Users
don't like to see warnings. If we have warning logs, they'll
complain. So let's try to make them complain as little as
possible, and only use warnings when you've encountered a *very*
odd situation, or when you need more information before
determining if something is correct.
An example: The Services plugin has two methods, doNickservNotice
and doChanservNotice, which doNotice dispatches to appropriately.
Now, we can't possibly predict all the possible messages that
ChanServ or NickServ might send to us. So I put a default clause
in there that just says, "Hey, this is an unexpected message from
ChanServ/NickServ: ..." I log this at warning level because I
want to know when there's a NickServ/ChanServ message I haven't
seen before. This works: the warning makes users report it.
Another example: We used to log failures in snarfers at the
warning level. But do the users really want to be warned when a
given "url" isn't valid? No! So now we just make it an info log,
so that users who care can still see why a snarfer didn't snarf,
but no one complains to us about it.
To find:
grep log.warning plugins/*.py
3. Spelling errors. They plague almost every large piece of
software. Supybot is no different, but we have a weapon against
them: find-strings.py. Give find-strings.py a set of files, and
it'll extract all the non-raw literal strings from the source code
and output them to a file, with the originating file, line number,
and string. Spell-checking Supybot is just a matter of taking
this 10,000 line file and an hour and running aspell over it,
correcting the errors in the original file as you find them.
To find:
find-strings.py src/*.py plugins/*.py scripts/supybot*
4. Pegging the CPU. It has happened in the past that bugs in Supybot
have caused 100% CPU usage. These are insidious, and generally
hard to track down. Here are our tools against them; we assuming
that the bug is reproducible.
First, I load the Debug plugin and settrace to a file, then I
quickly reproduce the bug, and let the CPU spin for awhile. Then
I kill the bot and check the trace file (which should be large).
I look for patterns that would indicate an infinite loop of some
sort.
Second, I strace the bot when it's looping. If I see output, it's
making syscalls; if I don't see any output, it's not. If it's
making syscalls, that might mean it's looping in the network
drivers somehow; if not, it's somewhere else.
Third, I check that no regexps could be causing it. They're
notorious for appearing safe, but actually hiding exponential
complexity code (the kind of code that strong cryptography is
based on).
After that, I pray harder :)

Ok, so you've decided to try out Supybot. That's great! The more
people who use Supybot, the more people can submit bugs and help us to
make it the best IRC bot in the world :)
First things first. You should have already read through INSTALL
before reading any further.
Ok, so let's assume your bot connected to the server fine and joined
the channels you told it to join. For now we'll assume you named your
bot "supybot" (you probably didn't, but it'll make it much clearer in
the examples that follow to assume that you did). We'll also assume
that you told it to join #channel (a nice generic name for a channel,
isn't it? :)) So what do you do with this bot that you just made to
join your channel? Try this in the channel:
supybot: list
Replacing "supybot" with the actual name you picked for your bot, of
course. Your bot should reply with a list of the plugins he currently
has loaded. At least Admin, Channel, Config, Misc, Owner, and User
should be there; if you used supybot-wizard to create your
configuration file you may have many more plugins loaded. The list
command can also be used to list the commands in a given plugin:
supybot: list Misc
Will list all the commands in the Misc plugin. If you want to see the
help for any command, just use the help command:
supybot: help help
supybot: help list
supybot: help load
Sometimes more than one plugin will have a given command; for
instance, the "list" command exists in both the Misc and Config
plugins (both loaded by default). List, in this case, defaults to the
Misc plugin, but you may want to get the help for the list command in
the Config plugin. In that case, you'll want to give your command
like this:
supybot: help config list
Anytime your bot tells you that a given command is defined in several
plugins, you'll want to use this syntax ("plugin command") to
disambiguate which plugin's command you wish to call. For instance,
if you wanted to call the Config plugin's list command, then you'd
need to say:
supybot: config list
Rather than just "list".
Now that you know how to deal with plugins having commands with the
same name, let's take a look at loading other plugins. If you didn't
use supybot-wizard, though, you might do well to try it before playing
around with loading plugins yourself: each plugin has its own
configure function that the wizard uses to setup the appropriate
registry entries if the plugin requires any.
Now, if you do want to play around with loading plugins, you're going
to need to have the owner capability. If you ran the wizard, then
chances are you already added an owner user for yourself. If not,
however, you can add one via the handy-dandy supybot-adduser script.
You'll want to run it while the bot is not running (otherwise it could
overwrite supybot-adduser's changes to your user database before you
get a chance to reload them). Just follow the prompts, and when it
asks if you want to give the user any capabilities, say yes and then
give yourself the "owner" capability (without the quotes), restart the
bot and you'll be ready to load some plugins!
Now, in order for the bot to recognize you as your owner user, you'll
have to identify with the bot. Open up a query window in your irc
client (/query should do it; if not, just know that you can't identify
in a channel because it requires sending your password to the bot).
Then type this:
help identify
And follow the instructions; the command you send will probably look
like this, with your owner user and password replaced:
identify myowneruser myuserpassword
The bot will tell you that "The operation succeeded" if you got the
right name and password. Now that you're identified, you can do
anything that requires any privilege: that includes all the commands
in the Owner and Admin plugins, which you may want to take a look at
(using the list and help commands, of course). One command in
particular that you might want to use (it's from the User plugin) is
the addhostmask command: it lets you add a hostmask to your user
record so the bot recognizes you by your hostmask instead of requiring
you to always identify with it before it recognizes you. Use the help
command to see how this command works. Here's how I often use it:
addhostmask myuser [hostmask] mypassword
You may not have seen that "[hostmask]" syntax before. Supybot allows
nested commands, which means that any command's output can be nested
as an argument to another command. The hostmask command from the Misc
plugin returns the hostmask of a given nick, but if given no
arguments, it returns the hostmask of the person giving the command.
So the command above adds the hostmask I'm currently using to my
user's list of recognized hostmasks. I'm only required to give
mypassword if I'm not already identified with the bot.
Now, with all that out of the way, we can continue telling you how to
load plugins :) Remember earlier when I told you to try "help
load"? That's the very command you'll be using. Basically, if you
want to load, say, the Fun plugin, then "load Fun". Simple, right?
If you need a list of the plugins you can load, you'll have to either
list the directory the plugins are in, or you'll have to check our
website -- look for the "Plugin index."
Another command you might find yourself needing somewhat often is the
"more" command. The IRC protocol limits messages to 512 bytes, 60 or
so of which must be devoted to some bookkeeping. Sometimes, however,
Supybot wants to send a message that's longer than that. What it
does, then, is break it into "chunks" and send the first one,
following it with "(X more messages)" where X is how many more chunks
there are. To get to these chunks, use the more command. One way to
try is to look at the default value of
supybot.replies.genericNoCapability -- it's so long that it'll
stretch across two messages.
<jemfinch|lambda> $config default
supybot.replies.genericNoCapability
<lambdaman> jemfinch|lambda: You're missing some capability
you need. This could be because you actually
possess the anti-capability for the capability
that's required of you, or because the channel
provides that anti-capability by default, or
because the global capabilities include that
anti-capability. Or, it could be because the
channel or the global defaultAllow is set to
False, meaning (1 more message)
<jemfinch|lambda> $more
<lambdaman> jemfinch|lambda: that no commands are allowed
unless explicitly in your capabilities. Either
way, you can't do what you want to do.
You should now have a solid foundation for using Supybot. Be sure to
check the help that is built-in to the bot itself if you have any
questions, and enjoy using Supybot!

So, you want to hack on Supybot? Cool! I'm glad -- more developers
means more users, and more users means better software (although I
suppose more developers means better software even without the
addition of more users :))
Anyway, there are a few things you should know before you submit your
code to be accepted into Supybot. The first, and most important
thing is that we really do value your contribution. We may say that
it's not appropriate for the core distribution and any number of
varying reasons, but regardless, we're happy that you're hacking on
Supybot and bending it to your will, and we'll be happy to post your
patch as long as it applies cleanly.
The second thing you should know is that, despite the fact that we're
happy you want to contribute to Supybot, we're not afraid to piss you
off by turning down your code. We won't hesitate to reject code
because it's "bad" or because it doesn't fit our style guidelines
(read docs/STYLE). We don't really care if it makes you angry or
makes you use another IRC bot; we're in the practice of writing good
software, not placating whiners. Despite this, we're not entirely
heartless, and if you've done something we're interested in, we're
willing to work with you and your code until such a time as it's
ready to be accepted into the core. But if, at some point, we say,
"This needs fixed" and you say, "I refuse to fix it," you can go put
your code on the patch tracker; our time together is done. Supybot
is #1 here -- we don't care about your feelings, we don't care about
jamessan's feelings, we don't care about jemfinch's feelings if it
means that the code quality and user experience of Supybot is to
suffer.
Anyway, the normal process is that you'll submit a few patches,
jemfinch will review them and tell you what needs to happen for them
to be accepted into the core, you'll fix those problems, jemfinch
will review them again, that cycle will repeat a few times. When
your code is to jemfinch's satisfaction, it'll be integrated into the
core. For many people, this is the end of the line. For some
others (perhaps you!), you'll continue to write patches for Supybot,
and your coding ability and commitment will be obvious through
those. If your code quality is consistently high enough that
jemfinch (or other Supybot developers) don't have to spend a
significant amount of time reviewing your code, you'll be added as a
developer on the SF.net project and given commit access to our CVS
repository. From then on, you can do what you want, but be aware
that the other developers are watching what you do -- if you have a
big architecture change, you should probably talk to them before you
commit.
So welcome aboard, and have fun hacking on Supybot!

@ -1,271 +0,0 @@
These are the interfaces for some of the objects you'll deal with if
you code for Supybot.
ircmsgs.IrcMsg:
This is the object that represents an IRC message. It has
several methods and attributes. The most important thing
about this class, however, is that it *is* hashable, and thus
*cannot* be modified. Do not change any attributes; any code
that modifies an IRC message is *broken* and should not
exist.
Interesting Methods:
__init__: One of the more complex initializers in
a class. It can be used in three different ways:
1) It can be given a string, as one received from
the server, which it will then parse into its
separate components and instantiate the class
with those components as attributes.
2) It can be given a command, some (optional)
arguments, and a (optional) prefix, and will
instantiate the class with those components as
attributes.
3) It can be given, in addition to any of the
above arguments, a 'msg' keyword argument that
will use the attributes of msg as defaults.
This exists to make it easier to copy
messages, since the class is immutable.
__str__: This returns the message in a string form
suitable for sending to a server.
__repr__: This returns the message in a form
suitable for eval(), assuming the name "IrcMsg" is
in your namespace and is bound to this class.
Interesting Attributes:
This is the meat of this class. These are
generally what you'll be looking at with IrcMsgs.
command: This is the command of the IrcMsg --
PRIVMSG, NOTICE, WHOIS, etc.
args: This is a tuple of the arguments to the
IrcMsg. Some messages have arguments, some don't,
depending on what command they are. You are, of
course, always assured that args exists and is a
tuple, though it might be empty.
prefix: This is the hostmask of the person/server
the message is from. In general, you won't be
setting this on your outgoing messages, but
incoming messages will always have one. This is
the whole hostmask; if the message was received
from a server, it'll be the server's hostmask; if
the message was received from a user, it'll be the
whole user hostmask. In that case, however, it's
also parsed out into the nick/user/host
attributes, which are probably more useful to
check for many purposes.
nick: If the message was sent by a user, this will
be the nick of the user. If it was sent by a
server, this will be the server's name (something
like calvino.freenode.net or similar).
user: If the message was sent by a user, this will
be the user string of the user -- what they put
into their IRC client for their "full name." If
it was sent by a server, it'll be the server's
name, again.
host: If the message was sent by a user, this will
be the host portion of their hostmask. If it was
sent by a server, it'll be the server's name (yet
again :))
irclib.Irc:
This is the object to handle everything about IRC except the
actual connection to the server itself. (*NOTE* that the
object actually received by commands in subclasses of
callbacks.Privmsg is an IrcObjectProxy, which is described
later. It augments the following interface with several
methods of its own to help plugin authors.)
Interesting Methods:
The two following messages (queueMsg and
sendMsg) are the methods by far most commonly
called by plugin authors. They're generally
the only methods you need to pay attention to
if you're writing plugins.
queueMsg: Queues a message for sending to the
server. The queue is generally FIFO, but it
does prioritize messages based on their command.
sendMsg: Queues a message for sending to the
server prior to any messages in the normal
queue. This is exactly a FIFO queue, no
reordering is done at all.
The following two methods are the most important
for people writing new IrcDrivers. Otherwise,
you really don't need to pay attention to them.
feedMsg: Feeds the Irc object a message for it
handle appropriately, as well as passing it on
to callbacks.
takeMsg: If the Irc object has a message it's
ready to send to the server, this will return
it. Otherwise, it will return None.
The next several methods are of far more marginal
utility. But someone may need them, so they're
documented here.
addCallback: Takes a callback to add to the list
of callbacks in the Irc object. See the
interface for IrcCallback for more information.
getCallback: Gets a callback by name, if it is
in the Irc object's list of callbacks. If it
it isn't, returns None.
removeCallback: Removes a callback by name.
Returns a list of the callbacks removed (since
it is technically possible to have multiple
callbacks with the same name. This list may
be empty.
__init__: Requires a nick. Optional arguments
include user and ident, which default to the
nick given, password, which defaults to the empty
password, and callbacks, a list of callbacks
(which defaults to nothing, an empty list).
reset: Resets the Irc object to its original
state, as well as sends a reset() to every
callbacks.
die: Kills the IRC object and all its callbacks.
Interesting attributes:
nick: The current nick of the bot.
prefix: The current prefix of the bot.
server: The current server the bot is connected to.
network: The current network name the bot is connected to.
afterConnect: False until the bot has received a
command sent after the connection is finished --
376, 377, or 422.
state: An IrcState object for this particular
connection. See the interface for the IrcState
object for more information.
irclib.IrcCallback:
Interesting Methods:
name: Returns the name of the callback. The
default implementation simply returns the name
of the class.
__call__: Called by the Irc object with itself
and the message whenever a message is fed to
the Irc object. Nothing is done with the return
value.
inFilter: Called by the Irc object with itself
and the message whenever a message is fed to
the Irc object. The return value should be an
IrcMsg object to be passed to the next callback
in the Irc's list of callbacks. If None is
returned, all processing stops. This gives
callbacks an oppurtunity to "filter" incoming
messages before general callbacks are given
them.
outFilter: Basically equivalent to inFilter,
except instead of being called on messages
as they enter the Irc object, it's called on
messages as they leave the Irc object.
die: Called when the parent Irc is told to
die. This gives callbacks an oppurtunity to
close open files, network connections, or
databases before they're deleted.
reset: Called when the parent Irc is told to
reset (which is generally when reconnecting
to the server). Most callbacks don't need
to define this.
Interesting attributes:
priority: Determines the priority of the
callback in the Irc object's list of
callbacks. Defaults to 99; the valid range
includes 0 through sys.maxint-1 (don't use
sys.maxint itself, that's reserved for the
Misc plugin). The lower the number, the
higher the priority. High priority
callbacks are called earlier in the
inFilter cycle, earlier in the __call__
cycle, and later in the outFilter cycle --
basically, they're given the first chances
on the way in and the last chances on the
way out.
callbacks.IrcObjectProxy:
IrcObjectProxy is a proxy for an irclib.Irc instance that
serves to provide a much fuller interface for handling
replies and errors as well as to handle the nesting of
commands. This is what you'll be dealing with almost all the
time when writing commands; when writing doCommand methods
(the kind you read about in the interface description of
irclib.IrcCallback) you'll be dealing with plain old
irclib.Irc objects.
Interesting methods:
reply: Called to reply to the current message
with a string that is to be the reply.
replySuccess, replyError: These reply with the
configured responses for success and generic
error, respectively. If an additional argument
is given, it's (intelligently) appended to the
generic message to be more specific.
error: Called to send an error reply to the
current message; not only does the response
indicate an error, but commands that error out
break the nested-command chain, which is
generally useful for not confusing the user :)
errorNoCapability: Like error, except it accepts
the capability that's missing and integrates it
into the configured error message for such
things. Also accepts an additional string for a
more descriptive message, if that's what you
want.
errorPossibleBug, errorNotRegistered,
errorNoUser, errorRequiresPrivacy: These methods
reply with the appropriate configured error
message for the conditions in their names; they
all take an additional arguments to be more
specific about the conditions they indicate, but
this argument is very rarely necessary.
getRealIrc: Returns the actual Irc object being
proxied for.
replies: Sends a collection of messages to a given
target, much like reply; except in this case, the user
can configure whether the messages will be sent
one-by-one or combined into a single message. Thus, the
method accepts a "prefixer" argument, which prefixes the
messages with a given string (or according to a given
function), a "joiner" string (or function) used to join
the messages into a single message if necessary, and an
onlyPrefixFirst argument which determines whether only
the first message will be prefixed when the messages are
sent separately (it defaults to False).

So here's a general *programming* introduction to what the different
modules do and what services they provide. It is, however, only an
introduction. Read the modules themselves for a much more detailed
explanation :)
fix.py: Stuff that Python should (but doesn't) include by default.
cdb.py: A constant database library, translated from C (and my O'Caml
version) More information available at
http://cr.yp.to/cdb.html. Not currently used since we
switched to PySQLite.
ansi.py: Contains different ANSI color sequences.
Mostly used by the debug module.
conf.py: The configuration file for the bot -- it sets a lot of
variables that other modules check for when they have
questions about what they need to do.
world.py: Just a dropping off place for some globals that need to be
shared among all the modules. It's obviously not used *a
lot*, but some things seem to fit better here than anywhere
else.
privmsgs.py: Basic stuff relating to callbacks.Privmsg, the base class
for most plugins.
callbacks.py: A few basic callbacks providing significant
functionality. You'll likely be inheriting from Privmsg
quite a bit.
ircdb.py: The users and channels databases are here, as well as the
IrcUser and IrcChannel classes. Look here when you want to
restrict a command to only certain users.
irclib.py: Provides the most important class in the irclib, Irc. It
represents a connection to an IRC server, but it's entirely
separate from the network implementation. It's connected
to the network (or whatever else drives it) by a "driver"
module which uses its feedMsg/takeMsg functions.
drivers.py: The baseclass (IrcDriver) for various drivers to drive
irclib.Irc classes. Also, the driving mechanism.
asyncoreDrivers.py: The asyncore-based drivers for use with the bot.
socketDrivers.py: The plain old socket-based drivers for use with the
bot.
twistedDrivers.py: The Twisted <http://www.twistedmatrix.com/> drivers
for use with the bot.
ircmsgs.py: The IrcMsg class (get to know it :)) and various functions
for making the creation of IrcMsgs easier.
ircutils.py: Various utility functions for Irc -- read the module to
see what goodies are there :)
schedule.py: A schedule driver (which is automatically registered with
the drivers module) to run things at a particular time,
or at specified periods of time.

*******************************************************************************
The plugins/Random.py included with the distribution has been
updated to use an argument-parsing module recently added to Supybot
but not yet documented. Still, all of the functions used in this
tutorial are available, so the code (as shown in this tutorial*
should still work.
*******************************************************************************
Ok, so you want to write a callback for Supybot. Good, then this is
the place to be. We're going to start from the top (the highest
level, where Supybot code does the most work for you) and move lower
after that.
So have you used Supybot? If not, you need to go use it, get a feel
for it, see how the various commands work and such.
So now that we know you've used Supybot, we'll start getting into
details.
First, the easiest way to start writing a module is to use the wizard
provided, scripts/newplugin.py. Here's an example session:
-----
functor% supybot-newplugin
What should the name of the plugin be? Random
Supybot offers two major types of plugins: command-based and regexp-
based. Command-based plugins are the kind of plugins you've seen most
when you've used supybot. They're also the most featureful and
easiest to write. Commands can be nested, for instance, whereas
regexp-based callbacks can't do nesting. That doesn't mean that
you'll never want regexp-based callbacks. They offer a flexibility
that command-based callbacks don't offer; however, they don't tie into
the whole system as well. If you need to combine a command-based
callback with some regexp-based methods, you can do so by subclassing
callbacks.PrivmsgCommandAndRegexp and then adding a class-level
attribute "regexps" that is a sets.Set of methods that are regexp-
based. But you'll have to do that yourself after this wizard is
finished :)
Do you want a command-based plugin or a regexp-based plugin? [command/
regexp] command
Sometimes you'll want a callback to be threaded. If its methods
(command or regexp-based, either one) will take a signficant amount
of time to run, you'll want to thread them so they don't block
the entire bot.
Does your plugin need to be threaded? [y/n] n
Your new plugin template is Random.py
functor%
-----
So that's what it looks like. Now let's look at the source code (if
you'd like to look at it in your programming editor, the whole plugin
is available as examples/Random.py):

So a few notes, before we customize it.
You'll probably want to change the copyright notice to be your name.
It wouldn't stick even if you kept my name, so you might as well :)
Describe what you want the plugin to do in the docstring. This is
used in supybot-wizard in order to explain to the user the purpose of
the module. It's also returned when someone asks the bot for help for
a given module (instead of help for a certain command). We'll change
this one to "Lots of stuff relating to random numbers."
Then there are the imports. The callbacks module is used (the class
you're given subclasses callbacks.Privmsg) but the privmsgs module
isn't used. That's alright; we can almost guarantee you'll use it, so
we go ahead and add the import to the template.
Then you see a "configure" function. This is the function that's
called when users decide to add your module in supybot-wizard. You'll
note that by default it simply registers the plugin to be
automatically loaded on startup. For many plugins this is all you
need; for more complex plugins, you might need to ask questions and
add commands based on the answers.
Now comes the meat of the plugin: the plugin class.
What you're given is a skeleton: a simple subclass of
callbacks.Privmsg for you to start with. Now let's add a command.
I don't know what you know about random number generators, but the
short of it is that they start at a certain number (a seed) and they
continue (via some somewhat complicated/unpredictable algorithm) from
there. This seed (and the rest of the sequence, really) is all nice
and packaged up in Python's random module, the Random object. So the
first thing we're going to have to do is give our plugin a Random
object.
Normally, when we want to give instances of a class an object, we'll
do so in the __init__ method. And that works great for plugins, too.
The one thing you have to be careful of is that you call the
superclass __init__ method at the end of your own __init__. So to add
this random.Random object to our plugin, we can replace the "pass"
statement with this:
def __init__(self):
self.rng = random.Random()
callbacks.Privmsg.__init__(self)
(rng is an abbreviation for "random number generator," in case you
were curious)
Do be careful not to give your __init__ any arguments (other than
self, of course). There's no way anything will ever get to them! If
you have some sort of initial values you need to get to your plugin
before it can do anything interesting, you should get those values
from the registry.
There's an easier way to get our plugin to have its own rng than to
define an __init__. Plugins are unique among classes because we're
always certain that there will only be one instance -- supybot doesn't
allow us to load multiple instances of a single plugin. So instead of
adding the rng in __init__, we can just add it as a attribute to the
class itself. Like so (replacing the "pass" statement again):
rng = random.Random()
And we save two lines of code and make our code a little more clear :)
Now that we have an RNG, we need some way to get random numbers. So
first, we'll add a command that simply gets the next random number and
gives it back to the user. It takes no arguments, of course (what
would you give it?). Here's the command, and I'll follow that with
the explanation of what each part means.
def random(self, irc, msg, args):
"""takes no arguments
Returns the next random number generated by the random number
generator.
"""
irc.reply(str(self.rng.random()))
And that's it! Pretty simple, huh? Anyway, you're probably wondering
what all that *means*. We'll start with the def statement:
def random(self, irc, msg, args):
What that does is define a command "random". You can call it by
saying "@random" (or whatever prefix character your specific bot
uses). The arguments are a bit less obvious. Self is self-evident
(hah!). irc is the Irc object passed to the command; msg is the
original IrcMsg object. But you're really not going to have to deal
with either of these too much (with the exception of calling irc.reply
or irc.error). What you're *really* interested in is the args arg.
That is a list of all the arguments passed to your command, pre-parsed
and already evaluated (i.e., you never have to worry about nested
commands, or handling double quoted strings, or splitting on
whitespace -- the work has already been done for you). You can read
about the Irc object in irclib.py (you won't find .reply or .error
there, though, because you're actually getting an IrcObjectProxy, but
that's beyond the level we want to describe here :)). You can read
about the msg object in ircmsgs.py. But again, you'll very rarely be
using these objects.
(In case you're curious, the answer is yes, you *must* name your
arguments (self, irc, msg, args). The names of those arguments is one
of the ways that supybot uses to determine which methods in a plugin
class are commands and which aren't. And while we're talking about
naming restrictions, all your commands should be named in
all-lowercase with no underscores. Before calling a command, supybot
always converts the command name to lowercase and removes all dashes
and underscores. On the other hand, you now know an easy way to make
sure a method is never called (even if its arguments are (self, irc,
msg, args), however unlikely that may be). Just name it with an
underscore or an uppercase letter in it :))
You'll also note that the docstring is odd. The wonderful thing about
the supybot framework is that it's easy to write complete commands
with help and everything: the docstring *IS* the help! Given the
above docstring, this is what a supybot does:
<jemfinch> @help random
<angryman> jemfinch: (random takes no arguments) -- Returns the
next random number from the random number generator.
Now on to the actual body of the function:
irc.reply(str(self.rng.random()))
irc.reply takes one simple argument: a string. The string is the
reply to be sent. Don't worry about length restrictions or anything
-- if the string you want to send is too big for an IRC message (and
oftentimes that turns out to be the case :)) the Supybot framework
handles that entirely transparently to you. Do make sure, however,
that you give irc.reply a string. It doesn't take anything else
(sometimes even unicode fails!). That's why we have
"str(self.rng.random())" instead of simply "self.rng.random()" -- we
had to give irc.reply a string.
Anyway, now that we have an RNG, we have a need for seed! Of course,
Python gives us a good seed already (it uses the current time as a
seed if we don't give it one) but users might want to be able to
repeat "random" sequences, so letting them set the seed is a good
thing. So we'll add a seed command to give the RNG a specific seed:
def seed(self, irc, msg, args):
"""<seed>
Sets the seed of the random number generator. <seed> must be
an int or a long.
"""
seed = privmsgs.getArgs(args)
try:
seed = long(seed)
except ValueError:
# It wasn't a valid long!
irc.error('<seed> must be a valid int or long.')
return
self.rng.seed(seed)
irc.replySuccess()
So this one's a bit more complicated. But it's still pretty simple.
The method name is "seed" so that'll be the command name. The
arguments are the same, the docstring is of the same form, so we don't
need to go over that again. The body of the function, however, is
significantly different.
privmsgs.getArgs is a function you're going to be seeing a lot of when
you write plugins for Supybot. What it does is basically give you the
right number of arguments for your comamnd. In this case, we want one
argument. But we might have been given any number of arguments by the
user. So privmsgs.getArgs joins them appropriately, leaving us with
one single "seed" argument (by default, it returns one argument as a
single value; more arguments are returned in a tuple/list). Yes, we
could've just said "seed = args[0]" and gotten the first argument, but
what if the user didn't pass us an argument at all? Then we've got to
catch the IndexError from args[0] and complain to the user about it.
privmsgs.getArgs, on the other hand, handles all that for us. If the
user didn't give us enough arguments, it'll reply with the help string
for the command, thus saving us the effort.
So we have the seed from privmsgs.getArgs. But it's a string. The
next three lines are pretty darn obvious: we're just converting the
string to a int of some sort. But if it's not, that's when we're
going to call irc.error. It has the same interface as we saw before
in irc.reply, but it makes sure to remind the user that an error has
been encountered (currently, that means it puts "Error: " at the
beginning of the message). After erroring, we return. It's important
to remember this return here; otherwise, we'll just keep going down
through the function and try to use this "seed" variable that never
got assigned. A good general rule of thumb is that any time you use
irc.error, you'll want to return immediately afterwards.
Then we set the seed -- that's a simple function on our rng object.
Assuming that succeeds (and doesn't raise an exception, which it
shouldn't, because we already read the documentation and know that it
should work) we reply to say that everything worked fine. That's what
irc.replySuccess says. By default, it has the very dry (and
appropriately robot-like) "The operation succeeded." but you're
perfectly welcome to customize it yourself -- the registry was written to
be modified!
So that's a bit more complicated command. But we still haven't dealt
with multiple arguments. Let's do that next.
So these random numbers are useful, but they're not the kind of random
numbers we usually want in Real Life. In Real Life, we like to tell
someone to "pick a number between 1 and 10." So let's write a
function that does that. Of course, we won't hardcode the 1 or the 10
into the function, but we'll take them as arguments. First the
function:
def range(self, irc, msg, args):
"""<start> <end>
Returns a number between <start> and <end>, inclusive (i.e., the number
can be either of the endpoints.
"""
(start, end) = privmsgs.getArgs(args, required=2)
try:
end = int(end)
start = int(start)
except ValueError:
irc.error('<start> and <end> must both be integers.')
return
# .randrange() doesn't include the endpoint, so we use end+1.
irc.reply(str(self.rng.randrange(start, end+1)))
Pretty simple. This is becoming old hat by now. The only new thing
here is the call to privmsgs.getArgs. We have to make sure, since we
want two values, to pass a keyword parameter "required" into
privmsgs.getArgs. Of course, privmsgs.getArgs handles all the
checking for missing arguments and whatnot so we don't have to.
The Random object we're using offers us a "sample" method that takes a
sequence and a number (we'll call it N) and returns a list of N items
taken randomly from the sequence. So I'll show you an example that
takes advantage of multiple arguments but doesn't use privmsgs.getArgs
(and thus has to handle its own errors if the number of arguments
isn't right). Here's the code:
def sample(self, irc, msg, args):
"""<number of items> [<text> ...]
Returns a sample of the <number of items> taken from the remaining
arguments. Obviously <number of items> must be less than the number
of arguments given.
"""
try:
n = int(args.pop(0))
except IndexError: # raised by .pop(0)
raise callbacks.ArgumentError
except ValueError:
irc.error('<number of items> must be an integer.')
return
if n > len(args):
irc.error('<number of items> must be less than the number '
'of arguments.')
return
sample = self.rng.sample(args, n)
irc.reply(utils.commaAndify(map(repr, sample)))
Most everything here is familiar. The difference between this and the
previous examples is that we're dealing with args directly, rather
than through getArgs. Since we already have the arguments in a list,
it doesn't make any sense to have privmsgs.getArgs smush them all
together into a big long string that we'll just have to re-split. But
we still want the nice error handling of privmsgs.getArgs. So what do
we do? We raise callbacks.ArgumentError! That's the secret juju that
privmsgs.getArgs is doing; now we're just doing it ourself. Someone
up our callchain knows how to handle it so a neat error message is
returned. So in this function, if .pop(0) fails, we weren't given
enough arguments and thus need to tell the user how to call us.
So we have the args, we have the number, we do a simple call to
random.sample and then we do this funky utils.commaAndify to it.
Yeah, so I was running low on useful names :) Anyway, what it does is
take a list of strings and return a string with them joined by a
comma, the last one being joined with a comma and "and". So the list
['foo', 'bar', 'baz'] becomes "foo, bar, and baz". It's pretty useful
for showing the user lists in a useful form. We map the strings with
repr() first just to surround them with quotes.
So we have one more example. Yes, I hear your groans, but it's
pedagogically useful :) This time we're going to write a command that
makes the bot roll a die. It'll take one argument (the number of
sides on the die) and will respond with the equivalent of "/me rolls a
__" where __ is the number the bot rolled. So here's the code:
def diceroll(self, irc, msg, args):
"""[<number of sides>]
Rolls a die with <number of sides> sides. The default number
of sides is 6.
"""
try:
n = privmsgs.getArgs(args, required=0, optional=1)
if not n:
n = 6
n = int(n)
except ValueError:
irc.error('Dice have integer numbers of sides. Use one.')
return
s = 'rolls a %s' % self.rng.randrange(1, n+1)
irc.reply(s, action=True)
There's a lot of stuff you haven't seen before in there. The most
important, though, is the first thing you'll notice that's different:
the privmsg.getArgs call. Here we're offering a default argument in
case the user is too lazy to supply one (or just wants a nice,
standard six-sided die :)) privmsgs.getArgs supports that; we'll just
tell it that we don't *need* any arguments (via required=0) and that
we *might like* one argument (optional=1). If the user provides an
argument, we'll get it -- if they don't, we'll just get an empty
string. Hence the "if not n: n = 6", where we provide the default.
You'll also note that irc.reply was given a keyword argument here,
"action". This means that the reply is to be made as an action rather
than a normal reply.
So that's our plugin. 5 commands, each building in complexity. You
should now be able to write most anything you want to do in Supybot.
Except regexp-based plugins, but that's a story for another day (and
those aren't nearly as cool as these command-based callbacks anyway
:)). Now we need to flesh it out to make it a full-fledged plugin.
TODO: Describe the registry and how to write a proper plugin configure
function.
We've written our own plugin from scratch (well, from the boilerplate
that we got from scripts/newplugin.py :)) and survived! Now go write
more plugins for supybot, and send them to me so I can use them too :)

@ -1,188 +0,0 @@
====================================================================
Code not following these style guidelines fastidiously is likely
(*very* likely) not to be accepted into the Supybot core.
====================================================================
Read PEP 8 (Guido's Style Guide) and know that we use almost all the
same style guidelines.
Maximum line length is 79 characters. 78 is a safer bet, though.
This is **NON-NEGOTIABLE**. Your code will not be accepted while you
are violating this guidline.
Identation is 4 spaces per level. No tabs. This also is
**NON-NEGOTIABLE**. Your code, again, will *never* be accepted while
you have literal tabs in it.
Single quotes are used for all string literals that aren't docstrings.
They're just easier to type.
Triple double quotes (""") are always used for docstrings.
Raw strings (r'' or r"") should be used for regular expressions.
Spaces go around all operators (except around '=' in default
arguments to functions) and after all commas (unless doing so keeps a
line within the 79 character limit).
Functions calls should look like this: "foo(bar(baz(x), y))". They
should not look like "foo (bar (baz (x), y))", or like
"foo(bar(baz(x), y) )" or like anything else. I hate extraneous
spaces.
Class names are StudlyCaps. Method and function names are camelCaps
(StudlyCaps with an initial lowercase letter). If variable and
attribute names can maintain readability without being camelCaps,
then they should be entirely in lowercase, otherwise they should also
use camelCaps. Plugin names are StudlyCaps.
Imports should always happen at the top of the module, one import per
line (so if imports need to be added or removed later, it can be done
easily).
Unless absolutely required by some external force, imports should be
ordered by the string length of the module imported. I just think it
looks prettier.
A blank line should be between all consecutive method declarations in
a class definition. Two blank lines should be between all
consecutive class definitions in a file. Comments are even better
than blank lines for separating classes.
Database filenames should generally begin with the name of the plugin
and the extension should be 'db'. plugins.DBHandler does this
already.
Whenever creating a file descriptor or socket, keep a reference
around and be sure to close it. There should be no code like this:
s = urllib2.urlopen('url').read()
Instead, do this:
fd = urllib2.urlopen('url')
try:
s = fd.read()
finally:
fd.close()
This is to be sure the bot doesn't leak file descriptors.
All plugin files should include a docstring decsribing what the
plugin does. This docstring will be returned when the user is
configuring the plugin. All plugin classes should also include a
docstring describing how to do things with the plugin; this docstring
will be returned when the user requests help on a plugin name.
Method docstrings in classes deriving from callbacks.Privmsg should
include an argument list as their first line, and after that a blank
line followed by a longer description of what the command does. The
argument list is used by the 'syntax' command, and the longer
description is used by the 'help' command.
Whenever joining more than two strings, use string interpolation, not
addition:
s = x + y + z # Bad.
s = '%s%s%s' % (x, y, z) # Good.
s = ''.join([x, y, z]) # Best, but not as general.
This has to do with efficiency; the intermediate string x+y is made
(and thus copied) before x+y+z is made, so it's less efficient.
People who use string concatenation in a for loop will be swiftly
kicked in the head.
When writing strings that have formatting characters in them, don't
use anything but %s unless you absolutely must. In particular, %d
should never be used, it's less general than %s and serves no useful
purpose. If you got the %d wrong, you'll get an exception that says,
"foo instance can't be converted to an integer." But if you use %s,
you'll get to see your nice little foo instance, if it doesn't
convert to a string cleanly, and if it does convert cleanly, you'll
get to see what you expect to see. Basically, %d just sucks.
As a corrolary to the above, note that sometimes %f is used, but on
when floats need to be formatted, e.g., %.2f.
Use the log module to its fullest; when you need to print some values
to debug, use self.log.debug to do so, and leave those statements in
the code (commented out) so they can later be re-enabled. Remember
that once code is buggy, it tends to have more bugs, and you'll
probably need those print statements again.
While on the topic of logs, note that we do not use % (i.e.,
str.__mod__) with logged strings; we simple pass the format
parameters as additional arguments. The reason is simple: the
logging module supports it, and it's cleaner (fewer tokens/glyphs) to
read.
While still on the topic of logs, it's also important to pick the
appropriate log level for given information.
DEBUG: Appropriate to tell a programmer *how* we're doing
something (i.e., debugging printfs, basically). If
you're trying to figure out why your code doesn't work,
DEBUG is the new printf -- use that, and leave the
statements in your code.
INFO: Appropriate to tell a user *what* we're doing, when what
we're doing isn't important for the user to pay attention
to. A user who likes to keep up with things should enjoy
watching our logging at the INFO level; it shouldn't be
too low-level, but it should give enough information that
it keeps him relatively interested at peak times.
WARNING: Appropriate to tell a user when we're doing something
that he really ought to pay attention to. Users should
see WARNING and think, "Hmm, should I tell the Supybot
developers about this?" Later, he should decide not to,
but it should give the user a moment to pause and think
about what's actually happening with his bot.
ERROR: Appropriate to tell a user when something has gone wrong.
Uncaught exceptions are ERRORs. Conditions that we
absolutely want to hear about should be errors. Things
that should *scare* the user should be errors.
CRITICAL: Not really appropriate. I can think of no absolutely
critical issue yet encountered in Supybot; the only
possible thing I can imagine is to notify the user that
the partition on which Supybot is running has filled up.
That would be a CRITICAL condition, but it would also be
hard to log :)
All plugins should have test cases written for them. Even if it
doesn't actually test anything but just exists, it's good to have the
test there so there's a place to add more tests later (and so we can
be sure that all plugins are adequately documented; PluginTestCase
checks that every command has documentation)
All uses of eval() that expect to get integrated in Supybot must be
approved by jemfinch, no exceptions. Chances are, it won't be
accepted. Have you looked at utils.safeEval?
SQL table names should be all-lowercase and include underscores to
separate words. This is because SQL itself is case-insensitive.
This doesn't change, however the fact that variable/member names
should be camel case.
SQL statements in code should put SQL words in ALL CAPS:
"""SELECT quote FROM quotes ORDER BY random() LIMIT 1""". This makes
SQL significantly easier to read.
Common variable names:
L => an arbitrary list.
t => an arbitrary tuple.
x => an arbitrary float.
s => an arbitrary string.
f => an arbitrary function.
p => an arbitrary predicate.
i,n => an arbitrary integer.
cb => an arbitrary callback.
db => a database handle.
fd => a file-like object.
msg => an ircmsgs.IrcMsg object.
irc => an irclib.Irc object (or proxy)
nick => a string that is an IRC nick.
channel => a string that is an IRC channel.
hostmask => a string that is a user's IRC prefix.
When the semantic functionality (that is, the "meaning" of a variable
is obvious from context, one of these names should be used. This
just makes it easier for people reading our code to know what a
variable represents without scouring the surrounding code.
Multiple variable assignments should always be surrounded with
parentheses -- i.e., if you're using the partition function, then
your assignment statement should look like
(good, bad) = partition(p, L). The parentheses make it obvious that
you're doing a multiple assignment, and that's important because I
hate reading code and wondering where a variable came from.

"""Beautiful Soup
Elixir and Tonic
"The Screen-Scraper's Friend"
The BeautifulSoup class turns arbitrarily bad HTML into a tree-like
nested tag-soup list of Tag objects and text snippets. A Tag object
corresponds to an HTML tag. It knows about the HTML tag's attributes,
and contains a representation of everything contained between the
original tag and its closing tag (if any). It's easy to extract Tags
that meet certain criteria.
A well-formed HTML document will yield a well-formed data
structure. An ill-formed HTML document will yield a correspondingly
ill-formed data structure. If your document is only locally
well-formed, you can use this to process the well-formed part of it.
#Example:
#--------
from BeautifulSoup import BeautifulSoup
text = '''<html>
<head><title>The Title</title></head>
<body>
<a class="foo" href="http://www.crummy.com/">Link <i>text (italicized)</i></a>
<a href="http://www.foo.com/">Link text 2</a>
</body>
</html>'''
soup = BeautifulSoup()
soup.feed(text)
print soup("a") #Returns a list of 2 Tag objects, one for each link in
#the source
print soup.first("a", {'class':'foo'})['href'] #Returns http://www.crummy.com/
print soup.first("title").contents[0] #Returns "The title"
print soup.first("a", {'href':'http://www.crummy.com/'}).first("i").contents[0]
#Returns "text (italicized)"
#Example of SQL-style attribute wildcards -- all four 'find' calls will
#find the link.
#----------------------------------------------------------------------
soup = BeautifulSoup()
soup.feed('''<a href="http://foo.com/">bla</a>''')
print soup.fetch('a', {'href': 'http://foo.com/'})
print soup.fetch('a', {'href': 'http://%'})
print soup.fetch('a', {'href': '%.com/'})
print soup.fetch('a', {'href': '%o.c%'})
#Example with horrible HTML:
#---------------------------
soup = BeautifulSoup()
soup.feed('''<body>
Go <a class="that" href="here.html"><i>here</i></a>
or <i>go <b><a href="index.html">Home</a>
</html>''')
print soup.fetch('a') #Returns a list of 2 Tag objects.
print soup.first(attrs={'href': 'here.html'})['class'] #Returns "that"
print soup.first(attrs={'class': 'that'}).first('i').contents[0] #returns "here"
This library has no external dependencies. It works with Python 1.5.2
and up. If you can install a Python extension, you might want to use
the ElementTree Tidy HTML Tree Builder instead:
http://www.effbot.org/zone/element-tidylib.htm
You can use BeautifulSoup on any SGML-like substance, such as XML or a
domain-specific language that looks like HTML but has different tag
names. For such purposes you may want to use the BeautifulStoneSoup
class, which knows nothing at all about HTML per se. I also reserve
the right to make the BeautifulSoup parser smarter between releases,
so if you want forwards-compatibility without having to think about
it, you might want to go with BeautifulStoneSoup.
Release status:
(I do a new release whenever I make a change that breaks backwards
compatibility.)
Current release:
Applied patch from Richie Hindle (richie at entrian dot com) that
makes tag.string a shorthand for tag.contents[0].string when the tag
has only one string-owning child.
1.2 "Who for such dainties would not stoop?" (2004/07/08): Applied
patch from Ben Last (ben at benlast dot com) that made
Tag.renderContents() correctly handle Unicode.
Made BeautifulStoneSoup even dumber by making it not implicitly
close a tag when another tag of the same type is encountered; only
when an actual closing tag is encountered. This change courtesy of
Fuzzy (mike at pcblokes dot com). BeautifulSoup still works as
before.
1.1 "Swimming in a hot tureen": Added more 'nestable' tags. Changed
popping semantics so that when a nestable tag is encountered, tags are
popped up to the previously encountered nestable tag (of whatever kind).
I will revert this if enough people complain, but it should make
more people's lives easier than harder.
This enhancement was suggested by Anthony Baxter (anthony at
interlink dot com dot au).
1.0 "So rich and green": Initial release.
Retreived from: http://www.crummy.com/software/BeautifulSoup/

already an open tag of that type in the stack means that the
previous tag of that type should be implicitly closed. However,
some tags can be nested. When a nestable tag is encountered,
it's okay to close all unclosed tags up to the last nestable

"""Python wrapper
for Amazon web APIs
This module allows you to access Amazon's web APIs,
to do things like search Amazon and get the results programmatically.
Described here:
http://www.amazon.com/webservices
You need a Amazon-provided license key to use these services.
Follow the link above to get one. These functions will look in
several places (in this order) for the license key:
- the "license_key" argument of each function
- the module-level LICENSE_KEY variable (call setLicense once to set it)
- an environment variable called AMAZON_LICENSE_KEY
- a file called ".amazonkey" in the current directory
- a file called "amazonkey.txt" in the current directory
- a file called ".amazonkey" in your home directory
- a file called "amazonkey.txt" in your home directory
- a file called ".amazonkey" in the same directory as amazon.py
- a file called "amazonkey.txt" in the same directory as amazon.py
Sample usage:
>>> import amazon
>>> amazon.setLicense('...') # must get your own key!
>>> pythonBooks = amazon.searchByKeyword('Python')
>>> pythonBooks[0].ProductName
u'Learning Python (Help for Programmers)'
>>> pythonBooks[0].URL
...
>>> pythonBooks[0].OurPrice
...
Other available functions:
- browseBestSellers
- searchByASIN
- searchByUPC
- searchByAuthor
- searchByArtist
- searchByActor
- searchByDirector
- searchByManufacturer
- searchByListMania
- searchSimilar
- searchByWishlist
Other usage notes:
- Most functions can take product_line as well, see source for possible values
- All functions can take type="lite" to get less detail in results
- All functions can take page=N to get second, third, fourth page of results
- All functions can take license_key="XYZ", instead of setting it globally
- All functions can take http_proxy="http://x/y/z" which overrides your system setting

r"""A class supporting chat-style (command/response) protocols.
This class adds support for 'chat' style protocols - where one side
sends a 'command', and the other sends a response (examples would be
the common internet protocols - smtp, nntp, ftp, etc..).
The handle_read() method looks at the input stream for the current
'terminator' (usually '\r\n' for single-line responses, '\r\n.\r\n'
for multi-line output), calling self.found_terminator() on its
receipt.
for example:
Say you build an async nntp client using this class. At the start
of the connection, you'll have self.terminator set to '\r\n', in
order to process the single-line greeting. Just before issuing a
'LIST' command you'll set it to '\r\n.\r\n'. The output of the LIST
command will be accumulated (using your own 'collect_incoming_data'
method) up to the terminator, and then control will be returned to
you - by calling your self.found_terminator() method.

"""Basic infrastructure for asynchronous socket service clients and servers.
There are only two ways to have a program on a single processor do "more
than one thing at a time". Multi-threaded programming is the simplest and
most popular way to do it, but there is another very different technique,
that lets you have nearly all the advantages of multi-threading, without
actually using multiple threads. it's really only practical if your program
is largely I/O bound. If your program is CPU bound, then pre-emptive
scheduled threads are probably what you really need. Network servers are
rarely CPU-bound, however.
If your operating system supports the select() system call in its I/O
library (and nearly all do), then you can use it to juggle multiple
communication channels at once; doing other work while your I/O is taking
place in the "background." Although this strategy can seem strange and
complex, especially at first, it is in many ways easier to understand and
control than multi-threaded programming. The module documented here solves
many of the difficult problems for you, making the task of building
sophisticated high-performance network servers and clients a snap.

available_languages
A list of languages available for use with babelfish.
translate( phrase, from_lang, to_lang )
Uses babelfish to translate phrase from from_lang to to_lang.
babelize(phrase, from_lang, through_lang, limit = 12, callback = None)
Uses babelfish to translate back and forth between from_lang and
through_lang until either no more changes occur in translation or
limit iterations have been reached, whichever comes first. Takes
an optional callback function which should receive a single
parameter, being the next translation. Without the callback
returns a list of successive translations.
It's only guaranteed to work if 'english' is one of the two languages
given to either of the translation methods.
Both translation methods throw exceptions which are all subclasses of
BabelizerError. They include
LanguageNotAvailableError
Thrown on an attempt to use an unknown language.
BabelfishChangedError
Thrown when babelfish.altavista.com changes some detail of their
layout, and babelizer can no longer parse the results or submit
the correct form (a not infrequent occurance).
BabelizerIOError
Thrown for various networking and IO errors.

"""
The relativedelta type is based on the specification of the excelent
work done by M.-A. Lemburg in his mx.DateTime extension. However,
notice that this type does *NOT* implement the same algorithm as
his work. Do *NOT* expect it to behave like mx.DateTime's counterpart.
There's two different ways to build a relativedelta instance. The
first one is passing it two date/datetime classes:
relativedelta(datetime1, datetime2)
And the other way is to use the following keyword arguments:
year, month, day, hour, minute, second, microsecond:
Absolute information.
years, months, weeks, days, hours, minutes, seconds, microseconds:
Relative information, may be negative.
weekday:
One of the weekday instances (MO, TU, etc). These instances may
receive a parameter N, specifying the Nth weekday, which could
be positive or negative (like MO(+1) or MO(-2). Not specifying
it is the same as specifying +1. You can also use an integer,
where 0=MO.
leapdays:
Will add given days to the date found, if year is a leap
year, and the date found is post 28 of february.
yearday, nlyearday:
Set the yearday or the non-leap year day (jump leap days).
These are converted to day/month/leapdays information.
Here is the behavior of operations with relativedelta:
1) Calculate the absolute year, using the 'year' argument, or the
original datetime year, if the argument is not present.
2) Add the relative 'years' argument to the absolute year.
3) Do steps 1 and 2 for month/months.
4) Calculate the absolute day, using the 'day' argument, or the
original datetime day, if the argument is not present. Then,
subtract from the day until it fits in the year and month
found after their operations.
5) Add the relative 'days' argument to the absolute day. Notice
that the 'weeks' argument is multiplied by 7 and added to
'days'.
6) Do steps 1 and 2 for hour/hours, minute/minutes, second/seconds,
microsecond/microseconds.
7) If the 'weekday' argument is present, calculate the weekday,
with the given (wday, nth) tuple. wday is the index of the
weekday (0-6, 0=Mon), and nth is the number of weeks to add
forward or backward, depending on its signal. Notice that if
the calculated date is already Monday, for example, using
(0, 1) or (0, -1) won't change the day.

"""Utilities for handling IEEE 754 floating point special values
This python module implements constants and functions for working with
IEEE754 double-precision special values. It provides constants for
Not-a-Number (NaN), Positive Infinity (PosInf), and Negative Infinity
(NegInf), as well as functions to test for these values.
The code is implemented in pure python by taking advantage of the
'struct' standard module. Care has been taken to generate proper
results on both big-endian and little-endian machines. Some efficiency
could be gained by translating the core routines into C.
See <http://babbage.cs.qc.edu/courses/cs341/IEEE-754references.html>
for reference material on the IEEE 754 floating point standard.
Further information on this package is available at
<http://www.analytics.washington.edu/statcomp/projects/rzope/fpconst/>.

"""
Python wrapper for Google web APIs
This module allows you to access Google's web APIs through SOAP,
to do things like search Google and get the results programmatically.
Described U{here <http://www.google.com/apis/>}
You need a Google-provided license key to use these services.
Follow the link above to get one. These functions will look in
several places (in this order) for the license key:
- the "license_key" argument of each function
- the module-level LICENSE_KEY variable (call setLicense once to set it)
- an environment variable called GOOGLE_LICENSE_KEY
- a file called ".googlekey" in the current directory
- a file called "googlekey.txt" in the current directory
- a file called ".googlekey" in your home directory
- a file called "googlekey.txt" in your home directory
- a file called ".googlekey" in the same directory as google.py
- a file called "googlekey.txt" in the same directory as google.py
Sample usage::
>>> import google
>>> google.setLicense('...') # must get your own key!
>>> data = google.doGoogleSearch('python')
>>> data.meta.searchTime
0.043221000000000002
>>> data.results[0].URL
'http://www.python.org/'
>>> data.results[0].title
