Introduction
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 :)
You should have already read through our install document (if you had to
manually install) before reading any further. Now we'll give you a whirlwind
tour as to how you can get Supybot setup and use Supybot effectively.
Initial Setup
Now that you have Supybot installed, you'll want to get it running. The
first thing you'll want to do is run supybot-wizard. Before running
supybot-wizard, you should be in the directory in which you want your
bot-related files to reside. The wizard will walk you through setting up a
base config file for your Supybot. Once you've completed the wizard, you will
have a config file called botname.conf. In order to get the bot running, run
'supybot botname.conf'.
Listing Commands
Ok, so let's assume your bot connected to the server 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'.
Making Supybot Recognize You
If you ran the wizard, then it is almost certainly the case that 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, 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 'myowneruser' and 'myuserpassword' 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 'hostmask add' command: it lets you add a
hostmask to your user record so the bot recognizes you by your hostmask instead
of requiring you always to identify with it before it recognizes you. Use the
'help' command to see how this command works. Here's how I often use it::
hostmask add 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.
Loading Plugins
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.
If you do want to play around with loading plugins, you're going to need to
have the owner capability.
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 Games plugin, then
'load Games'. Simple, right? If you need a list of the plugins you can load,
you'll have to list the directory the plugins are in (using whatever command is
appropriate for your operating system, either 'ls' or 'dir').
Getting More From Your Supybot
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.
So basically, the bot keeps, for each person it sees, a list of "chunks"
which are "released" one at a time by the 'more' command. In fact, you can
even get the more chunks for another user: if you want to see another chunk in
the last command jemfinch gave, for instance, you would just say 'more
jemfinch' after which, his "chunks" now belong to you. So, you would just need
to say 'more' to continue seeing chunks from jemfinch's initial command.
Final Word
You should now have a solid foundation for using Supybot. You can use the
'list' command to see what plugins your bot has loaded and what commands are in
those plugins; you can use the 'help' command to see how to use a specific
command, and you can use the 'more' command to continue a long response from
the bot. With these three commands, you should have a strong basis with which
to discover the rest of the features of Supybot!
Do be sure to read our other documentation and make use of the resources we
provide for assistance; this website, the forums on it, and, of course,
#supybot on irc.freenode.net if you run into any trouble!

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::

then four attributes that you need to modify for your bot and preferably keep
up with as you develop it: ``__version__``, ``__author__``,
``__contributors__``, ``__url__``.
__version__ is just a version string representing the current working version
of the plugin, and can be anything you want. If you use some sort of RCS, this
would be a good place to have it automatically increment the version string for
any time you edit any of the files in this directory. We'll just make ours

__author__ should be an instance of the supybot.Author class. A supybot.Author
is simply created by giving it a full name, a short name (preferably IRC nick),
and an e-mail address (all of these are optional, though at least the second
one is expected). So, for example, to create my Author user (though I get to
cheat and use supybot.authors.strike since I'm a main dev, muahaha), I would
do:

__author__ = supybot.Author('Daniel DiPaolo', 'Strike',
'somewhere@someplace.xxx')
Keep this in mind as we get to the next item...
__contributors__ is a dictionary mapping supybot.Author instances to lists of
things they contributed. If someone adds a command named foo to your plugin,
the list for that author should be ["foo"], or perhaps even ["added foo

``__contributors__`` is a dictionary mapping supybot.Author instances to lists
of things they contributed. If someone adds a command named foo to your
plugin, the list for that author should be ``["foo"]``, or perhaps even
``["added foo command"]``. The main author shouldn't be referenced here, as it
is assumed that everything that wasn't contributed by someone else was done by
the main author. For now we have no contributors, so we'll leave it blank.

plugin. Since this is just an example, we'll leave this blank.

@ -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.

Using Supybot's utils module
----------------------------
Supybot provides a wealth of utilities for plugin writers in the supybot.utils
module, this tutorial describes these utilities and shows you how to use them.
str.py
======
The Format Function
The supybot.utils.str module provides a bunch of utility functions for
handling string values. This section contains a quick rundown of all of the
functions available, along with descriptions of the arguments they take. First
and foremost is the format function, which provides a lot of capability in
just one function that uses string-formatting style to accomplish a lot. So
much so that it gets its own section in this tutorial. All other functions
will be in other sections. format takes several arguments - first, the format
string (using the format characters described below), and then after that,
each individual item to be formatted. Do not attempt to use the % operator to
do the formatting because that will fall back on the normal string formatting
operator. The format function uses the following string formatting characters.
* % - literal "%"
* i - integer
* s - string
* f - float
* r - repr
* b - form of the verb "to be" (takes an int)
* h - form of the verb "to have" (takes an int)
* L - commaAndify (takes a list of strings or a tuple of ([strings], and))
* p - pluralize (takes a string)
* q - quoted (takes a string)
* n - n items (takes a 2-tuple of (n, item) or a 3-tuple of (n, between, item))
* t - time, formatted (takes an int)
* u - url, wrapped in braces
Here are a few examples to help elaborate on the above descriptions:
>>> format("Error %q has been reported %n. For more information, see %u.",
"AttributeError", (5, "time"), "http://supybot.com")
'Error "AttributeError" has been reported 5 times. For more information,
see <http://supybot.com>.'
>>> i = 4
>>> format("There %b %n at this time. You are only allowed %n at any given
time", i, (i, "active", "thread"), (5, "active", "thread"))
'There are 4 active threads at this time. You are only allowed 5 active
threads at any given time'
>>> i = 1
>>> format("There %b %n at this time. You are only allowed %n at any given
time", i, (i, "active", "thread"), (5, "active", "thread"))
'There is 1 active thread at this time. You are only allowed 5 active
threads at any given time'
>>> ops = ["foo", "bar", "baz"]
>>> format("The following %n %h the %s capability: %L", (len(ops), "user"),
len(ops), "op", ops)
'The following 3 users have the op capability: foo, bar, and baz'
As you can see, you can combine all sorts of combinations of formatting
strings into one. In fact, that was the major motivation behind format. We
have specific functions that you can use individually for each of those
formatting types, but it became much easier just to use special formatting
chars and the format function than concatenating a bunch of strings that were
the result of other utils.str functions.
The Other Functions
These are the functions that can't be handled by format. They are sorted in
what I perceive to be the general order of usefulness (and I'm leaving the
ones covered by format for the next section).
* ellipsisify(s, n) - Returns a shortened version of a string. Produces up
to the first n chars at the nearest word boundary.
- s: the string to be shortened
- n: the number of characters to shorten it to
* perlReToPythonRe(s) - Converts a Perl-style regexp (e.g., "/abcd/i" or
"m/abcd/i") to an actual Python regexp (an re object)

structures.py
=============
Intro
This module provides a number of useful data structures that aren't found in
the standard Python library. For the most part they were created as needed for
the bot and plugins themselves, but they were created in such a way as to be
of general use for anyone who needs a data structure that performs a like
duty. As usual in this document, I'll try and order these in order of
usefulness, starting with the most useful.
The queue classes
The structures module provides two general-purpose queue classes for you to
use. The "queue" class is a robust full-featured queue that scales up to
larger sized queues. The "smallqueue" class is for queues that will contain
fewer (less than 1000 or so) items. Both offer the same common interface,
which consists of:
* a constructor which will optionally accept a sequence to start the queue
off with
* enqueue(item) - adds an item to the back of the queue
* dequeue() - removes (and returns) the item from the front of the queue
* peek() - returns the item from the front of the queue without removing
it
* reset() - empties the queue entirely
In addition to these general-use queue classes, there are two other more
specialized queue classes as well. The first is the "TimeoutQueue" which holds
a queue of items until they reach a certain age and then they are removed from
the queue. It features the following:
* TimeoutQueue(timeout, queue=None) - you must specify the timeout (in
seconds) in the constructor. Note that you can also optionally pass it a
queue which uses any implementation you wish to use whether it be one of
the above (queue or smallqueue) or if it's some custom queue you create
that implements the same interface. If you don't pass it a queue instance
to use, it will build its own using smallqueue.
* reset(), enqueue(item), dequeue() - all same as above queue classes
* setTimeout(secs) - allows you to change the timeout value
And for the final queue class, there's the "MaxLengthQueue" class. As you may
have guessed, it's a queue that is capped at a certain specified length. It
features the following:
* MaxLengthQueue(length, seq=()) - the constructor naturally requires that
you set the max length and it allows you to optionally pass in a sequence
to be used as the starting queue. The underlying implementation is
actually the queue from before.
* enqueue(item) - adds an item onto the back of the queue and if it would
push it over the max length, it dequeues the item on the front (it does
not return this item to you)
* all the standard methods from the queue class are inherited for this class
The Other Structures
The most useful of the other structures is actually very similar to the
"MaxLengthQueue". It's the "RingBuffer", which is essentially a MaxLengthQueue
which fills up to its maximum size and then circularly replaces the old
contents as new entries are added instead of dequeuing. It features the
following:
* RingBuffer(size, seq=()) - as with the MaxLengthQueue you specify the
size of the RingBuffer and optionally give it a sequence.
* append(item) - adds item to the end of the buffer, pushing out an item
from the front if necessary
* reset() - empties out the buffer entirely
* resize(i) - shrinks/expands the RingBuffer to the size provided
* extend(seq) - append the items from the provided sequence onto the end
of the RingBuffer
The next data structure is the TwoWayDictionary, which as the name implies is
a dictionary in which key-value pairs have mappings going both directions. It
features the following:
* TwoWayDictionary(seq=(), **kwargs) - Takes an optional sequence of (key,
value) pairs as well as any key=value pairs specified in the constructor
as initial values for the two-way dict.
* other than that, no extra features that a normal Python dict doesn't
already offer with the exception that any (key, val) pair added to the
dict is also added as (val, key) as well, so the mapping goes both ways.
Elements are still accessed the same way you always do with Python
'dict's.
There is also a MultiSet class available, but it's very unlikely that it will
serve your purpose, so I won't go into it here. The curious coder can go check
the source and see what it's all about if they wish (it's only used once in our
code, in the Relay plugin).

The web portion of Supybot's utils module is mainly used for retrieving data
from websites but it also has some utility functions pertaining to HTML and
email text as well. The functions in web are listed below, once again in order
of usefulness.
* getUrl(url, size=None, headers=None) - gets the data at the URL provided
and returns it as one large string
- url: the location of the data to be retrieved or a urllib2.Request
object to be used in the retrieval
- size: the maximum number of bytes to retrieve, defaults to None,
meaning that it is to try to retrieve all data
- headers: a dictionary mapping header types to header data
* getUrlFd(url, headers=None) - returns a file-like object for a url
- url: the location of the data to be retrieved or a urllib2.Request
object to be used in the retrieval
- headers: a dictionary mapping header types to header data
* htmlToText(s, tagReplace=" ") - strips out all tags in a string of HTML,
replacing them with the specified character
- s: the HTML text to strip the tags out of
- tagReplace: the string to replace tags with
* strError(e) - pretty-printer for web exceptions, returns a descriptive
string given a web-related exception
- e: the exception to pretty-print
* mungeEmail(s) - a naive e-mail obfuscation function, replaces "@" with
"AT" and "." with "DOT"
- s: the e-mail address to obfuscate
* getDomain(url) - returns the domain of a URL
- url: the URL in question
The Best of the Rest

Highlights the most useful of the remaining functionality in supybot.utils
Intro
Rather than document each of the remaining portions of the supybot.utils
module, I've elected to just pick out the choice bits from specific parts and
document those instead. Here they are, broken out by module name.
supybot.utils.file - file utilities
* touch(filename) - updates the access time of a file by opening it for
writing and immediately closing it
* mktemp(suffix="") - creates a decent random string, suitable for a
temporary filename with the given suffix, if
provided
* the AtomicFile class - used for files that need to be atomically
written, i.e., if there's a failure the original
file remains unmodified. For more info consult
file.py in src/utils
supybot.utils.gen - general utilities
* timeElapsed(elapsed, [lots of optional args]) - given the number of
seconds elapsed, returns a string with the English description of the
amount of time passed, consult gen.py in src/utils for the exact
argument list and documentation if you feel you could use this
function.
* exnToString(e) - improved exception-to-string function. Provides nicer
output than a simple str(e).
* InsensitivePreservingDict class - a dict class that is case-insensitive
when accessing keys
supybot.utils.iter - iterable utilities
* len(iterable) - returns the length of a given iterable
* groupby(key, iterable) - equivalent to the itertools.groupby function
available as of Python 2.4. Provided for
backwards compatibility.
* any(p, iterable) - Returns true if any element in the iterable satisfies
the predicate p
* all(p, iterable) - Returns true if all elements in the iterable satisfy
the predicate p
* choice(iterable) - Returns a random element from the iterable

Using Supybot's utils module
============================
Supybot provides a wealth of utilities for plugin writers in the supybot.utils
module, this tutorial describes these utilities and shows you how to use them.
str.py
======
The Format Function
-------------------
The supybot.utils.str module provides a bunch of utility functions for
handling string values. This section contains a quick rundown of all of the
functions available, along with descriptions of the arguments they take. First
and foremost is the format function, which provides a lot of capability in
just one function that uses string-formatting style to accomplish a lot. So
much so that it gets its own section in this tutorial. All other functions
will be in other sections. format takes several arguments - first, the format
string (using the format characters described below), and then after that,
each individual item to be formatted. Do not attempt to use the % operator to
do the formatting because that will fall back on the normal string formatting
operator. The format function uses the following string formatting characters.
* % - literal ``%``
* i - integer
* s - string
* f - float
* r - repr
* b - form of the verb ``to be`` (takes an int)
* h - form of the verb ``to have`` (takes an int)
* L - commaAndify (takes a list of strings or a tuple of ([strings], and))
* p - pluralize (takes a string)
* q - quoted (takes a string)
* n - n items (takes a 2-tuple of (n, item) or a 3-tuple of (n, between, item))
* t - time, formatted (takes an int)
* u - url, wrapped in braces
Here are a few examples to help elaborate on the above descriptions::
>>> format("Error %q has been reported %n. For more information, see %u.",
"AttributeError", (5, "time"), "http://supybot.com")
'Error "AttributeError" has been reported 5 times. For more information,
see <http://supybot.com>.'
>>> i = 4
>>> format("There %b %n at this time. You are only allowed %n at any given
time", i, (i, "active", "thread"), (5, "active", "thread"))
'There are 4 active threads at this time. You are only allowed 5 active
threads at any given time'
>>> i = 1
>>> format("There %b %n at this time. You are only allowed %n at any given
time", i, (i, "active", "thread"), (5, "active", "thread"))
'There is 1 active thread at this time. You are only allowed 5 active
threads at any given time'
>>> ops = ["foo", "bar", "baz"]
>>> format("The following %n %h the %s capability: %L", (len(ops), "user"),
len(ops), "op", ops)
'The following 3 users have the op capability: foo, bar, and baz'
As you can see, you can combine all sorts of combinations of formatting
strings into one. In fact, that was the major motivation behind format. We
have specific functions that you can use individually for each of those
formatting types, but it became much easier just to use special formatting
chars and the format function than concatenating a bunch of strings that were
the result of other utils.str functions.
The Other Functions
-------------------
These are the functions that can't be handled by format. They are sorted in
what I perceive to be the general order of usefulness (and I'm leaving the
ones covered by format for the next section).
* ellipsisify(s, n) - Returns a shortened version of a string. Produces up to
the first n chars at the nearest word boundary.
- s: the string to be shortened
- n: the number of characters to shorten it to
* perlReToPythonRe(s) - Converts a Perl-style regexp (e.g., "/abcd/i" or
"m/abcd/i") to an actual Python regexp (an re object)
- s: the regexp string
* perlReToReplacer(s) - converts a perl-style replacement regexp (eg,
"s/foo/bar/g") to a Python function that performs such a replacement
- s: the regexp string
* dqrepr(s) - Returns a repr() of s guaranteed to be in double quotes.
(Double Quote Repr)
- s: the string to be double-quote repr()'ed
* toBool(s) - Determines whether or not a string means True or False and
returns the appropriate boolean value. True is any of "true", "on",
"enable", "enabled", or "1". False is any of "false", "off", "disable",
"disabled", or "0".
- s: the string to determine the boolean value for
* rsplit(s, sep=None, maxsplit=-1) - functionally the same as str.split in the
Python standard library except splitting from the right instead of the left.
Python 2.4 has str.rsplit (which this function defers to for those versions
>= 2.4), but Python 2.3 did not.
- s: the string to be split
- sep: the separator to split on, defaults to whitespace
- maxsplit: the maximum number of splits to perform, -1 splits all possible
splits.
* normalizeWhitespace(s) - reduces all multi-spaces in a string to a single
space
- s: the string to normalize
* depluralize(s) - the opposite of pluralize
- s: the string to depluralize
* unCommaThe(s) - Takes a string of the form "foo, the" and turns it into "the
foo"
- s: string, the
* distance(s, t) - computes the levenshtein distance (or "edit distance")
between two strings
- s: the first string
- t: the second string
* soundex(s, length=4) - computes the soundex for a given string
- s: the string to compute the soundex for
- length: the length of the soundex to generate
* matchCase(s1, s2) - Matches the case of the first string in the second
string.
- s1: the first string
- s2: the string which will be made to match the case of the first

Converters alone are a pretty powerful tool, but for even more advanced (yet
simpler!) argument handling you may want to use contexts. Contexts describe how
the converters are applied to the arguments, while the converters themselves

Converter List
==============
What converters are available for me to use?
Below is a list of all the available converters to use with wrap. If the
converter accepts any arguments, they are listed after it and if they are
optional, the default value is shown.
"id", kind="integer"
Returns something that looks like an integer ID number. Takes an optional
* id, kind="integer"
- Returns something that looks like an integer ID number. Takes an optional
"kind" argument for you to state what kind of ID you are looking for,
though this doesn't affect the integrity-checking. Basically requires that
the argument be an integer, does no other integrity-checking, and provides
a nice error message with the kind in it.
"ip"
Checks and makes sure the argument looks like a valid IP and then returns
* ip
- Checks and makes sure the argument looks like a valid IP and then returns
it.
"int", type="integer", p=None
Gets an integer. The "type" text can be used to customize the error message
* int, type="integer", p=None
- Gets an integer. The "type" text can be used to customize the error message
received when the argument is not an integer. "p" is an optional predicate
to test the integer with. If p(i) fails (where i is the integer arg parsed
out of the argument string), the arg will not be accepted.
"index"
Basically ("int", "index"), but with a twist. This will take a 1-based
* index
- Basically ("int", "index"), but with a twist. This will take a 1-based
index and turn it into a 0-based index (which is more useful in code). It
doesn't transform 0, and it maintains negative indices as is (note that it
does allow them!).
"color"
Accepts arguments that describe a text color code (e.g., "black", "light
* color
- Accepts arguments that describe a text color code (e.g., "black", "light
blue") and returns the mIRC color code for that color. (Note that many
other IRC clients support the mIRC color code scheme, not just mIRC)
"now"
Simply returns the current timestamp as an arg, does not reference or
* now
- Simply returns the current timestamp as an arg, does not reference or
modify the argument list.
"url"
Checks for a valid URL.
* url
"httpUrl"
Checks for a valid HTTP URL.
- Checks for a valid URL.
"long", type="long"
Basically the same as int minus the predicate, except that it converts the
* httpUrl
- Checks for a valid HTTP URL.
* long, type="long"
- Basically the same as int minus the predicate, except that it converts the
argument to a long integer regardless of the size of the int.
"float", type="floating point number"
Basically the same as int minus the predicate, except that it converts the
* float, type="floating point number"
- Basically the same as int minus the predicate, except that it converts the
argument to a float.
"nonInt", type="non-integer value"
Accepts everything but integers, and returns them unchanged. The "type"
* nonInt, type="non-integer value"
- Accepts everything but integers, and returns them unchanged. The "type"
value, as always, can be used to customize the error message that is
displayed upon failure.
"positiveInt"
Accepts only positive integers.
* positiveInt
"nonNegativeInt"
Accepts only non-negative integers.
- Accepts only positive integers.
"letter"
Looks for a single letter. (Technically, it looks for any one-element
* nonNegativeInt
- Accepts only non-negative integers.
* letter
- Looks for a single letter. (Technically, it looks for any one-element
sequence).
"haveOp", action="do that"
Simply requires that the bot have ops in the channel that the command is
* haveOp, action="do that"
- Simply requires that the bot have ops in the channel that the command is
called in. The action parameter completes the error message: "I need to be
opped to ...".
"expiry"
Takes a number of seconds and adds it to the current time to create an
* expiry
- Takes a number of seconds and adds it to the current time to create an
expiration timestamp.
"literal", literals, errmsg=None
Takes a required sequence or string (literals) and any argument that
* literal, literals, errmsg=None
- Takes a required sequence or string (literals) and any argument that
uniquely matches the starting substring of one of the literals is
transformed into the full literal. For example, with ("literal", ("bar",
"baz", "qux")), you'd get "bar" for "bar", "baz" for "baz", and "qux" for
any of "q", "qu", or "qux". "b" and "ba" would raise errors because they
don't uniquely identify one of the literals in the list. You can override
errmsg to provide a specific (full) error message, otherwise the default
argument error message is displayed.

* text
- Takes the rest of the arguments as one big string. Note that this differs
from the "anything" context in that it clobbers the arg string when it's
done. Using any converters after this is most likely incorrect.
"glob"
Gets a glob string. Basically, if there are no wildcards ('"*"', "?") in
the argument, returns *string*, making a glob string that matches anything
