PBot

About PBot

PBot is an IRC bot written in Perl in pragma-’s spare time.

Source

PBot’s source may be found at these repositories:

The URL for the source of any loaded modules may be found by using the factinfo command:

<pragma-> factinfo ##c faq
   <PBot> faq: Module loaded by pragma- on Fri Dec 31 02:34:04 2004 -> https://github.com/pragma-/pbot/blob/master/modules/cfaq.pl, used 512 times (last by ecrane)

Bot Channel

You may test/play with PBot in the #pbot2 channel on irc.freenode.net.

Trigger

All of PBot’s commands may begin with its name or its trigger, or be followed by its name.

The trigger character defaults to exclaimation mark !.

Note that commands need not be submitted to the channel; you can /msg it instead. If you /msg PBot, it will respond with a private message in return. In private message, you do not need to specify its name or one of the trigger symbols.

<pragma-> !hi
<pragma-> hi, PBot
<pragma-> PBot: hi

Embedded trigger

Many commands may be triggered from within a sentence by adding curly braces or backticks around the command after the trigger. You can embed up to three commands in one message.

If the sentence begins with a nick that is currently in the channel, the command’s response will be prefixed with that nick.

<pragma-> Alice: Check out !{K&R} for a good book on C.  !`H&S` is also a great reference manual.
   <PBot> Alice: K&R is The C Programming Language, 2nd edition, by Kernighan and Ritchie - http://wayback.archive-it.org/5263/20150203070038/http://cm.bell-labs.com/cm/cs/cbook/ - errata: http://www.iso-9899.info/2ediffs.html
   <PBot> Alice: H&S is "C - A Reference Manual" by Harbison & Steele; a reference for C on par with K&R - http://www.amazon.com/Reference-Manual-Samuel-P-Harbison/dp/013089592X

Directing output to a user

There are several ways to direct PBot to prepend the nickname of a specific person to a command in a channel.

You may state the nickname after the command (if the command doesn’t take arguments):

<pragma-> PBot: version defrost
   <PBot> defrost: PBot revision 387 2012-10-07

You may prefix a command with the nickname:

<pragma-> randomjoe: !help cjeopardy
   <PBot> randomjoe: To learn all about cjeopardy, see http://www.iso-9899.info/wiki/PBot#cjeopardy

You may use embedded command triggering in a message addressed at a nickname:

<pragma-> randomjoe: PBot is at !{version}, to learn more check out its !{help} page
   <PBot> randomjoe: PBot revision 387 2012-10-07
   <PBot> randomjoe: To learn all about me, see http://www.iso-9899.info/wiki/PBot

tell

You may use the tell <nick> about <command> syntax:

<pragma-> PBot: tell defrost about help cc
   <PBot> defrost: To learn all about cc, see http://www.iso-9899.info/wiki/PBot#cc

Registry

PBot’s behavior can be customized via a central registry of key/value pairs segregated by sections.

There are two types of registry values: literals and arrays. Literals can be strings, floats or integers. Arrays are comma-separated lists of literals.

Overriding registry values per-channel

Some key/value pairs belonging to a specific section may be overridden on a per-channel basis by setting the key/value in a channel-specific section.

For example, the bot’s trigger is defined in general.trigger. You may add a trigger key in #channel to override the trigger value for that channel: #channel.trigger.

For another example, the anti-flood max lines is defined in antiflood.chat_flood_threshold. To override this setting in #neatchannel, you can set #neatchannel.chat_flood_threshold.

regadd

regadd adds a new registry value to a specific section/channel.

Usage: regadd <section> <key> <value>

For example, to override the trigger for #mychannel to be any of ,, ! or %:

<pragma> regadd #mychannel trigger [,!%]
  <PBot> [#mychannel] trigger set to [,!%]

Some registry values can be regular expressions, like the above trigger example. Setting general.trigger to the character class [,!%] means that it will respond to , ! and % as trigger characters on a general basis.

regrem

regrem removes a registry key from a specific section/channel.

Usage: regrem <section> <key>

regshow

regshow displays the type and value of a specific key.

Usage: regshow <section> <key>

<pragma> regshow antiflood chat_flood_punishment
  <PBot> [antiflood] chat_flood_punishment: 60,300,3600,86400,604800,2419200 [array]

regset

regset sets the meta-data values for a specific registry key. See registry meta-data list.

If you omit the <key> argument, it will list all the defined keys and values for the registry item. If you specify <key> but omit <value>, it will show the value for that specific key.

Usage: regset <section> <item> [key [value]]

 <pragma> regset irc botnick value pangloss
        * PBot changed nick to pangloss
<pangloss> [irc] botnick: 'value' set to 'pangloss'

Registry metadata list

This is a list of recognized registry meta-data keys.

type: sets the type of this registry key; values can be text (literal) or array.
value: the value of this registry key.
private: whether the value of the registry key is displayed in regset, regshow or regfind. If set to a true value, the value of the registry key will be shown as “<private>”.

regunset

regunset deletes a meta-data key from a registry key.

Usage: regunset <section> <item> <key>

regchange

regchange changes the value of a registry item using a regular substitution expression.

Usage: regchange <section> <item> s/<pattern>/<replacement>/

<pragma> regadd foo bar Hello, world!
  <PBot> [foo] bar set to Hello, world!
<pragma> regchange foo bar s/world/universe/
  <PBot> [foo] bar set to Hello, universe!

regfind

regfind searches for registry items, and may optionally show the values of all matching items.

Usage: regfind [-showvalues] [-section <section>] <regex>

To limit the search to a specific section, use -section <section>. To dump the entire registry, use regfind -showvalues .*

Creating array values

Use the regset command to change the type meta-data value to “array”, and set the registry value to a comma-separated list of values.

<pragma> regadd foo animals aardvark, badger, cat, dingo
  <PBot> [foo] animals set to aardvark, badger, cat, dingo
<pragma> regset foo animals type array
  <PBot> [foo] animals: 'type' set to 'array'

Factoids

Channel namespaces

Factoids added in one channel may be called/triggered in another channel or in private message, providing that the other channel doesn’t already have a factoid of the same name (in which case that channel’s factoid will be triggered).

Factoids may also be added to a special channel named global or .*. Factoids that are set in this channel will be accessible to any channel, including private messages. However, factoids that are set in a specific channel will override factoids of the same name that are set in the global channel or other channels.

For example, a factoid named malloc set in ##c will be called instead of malloc set in global, if the factoid were triggered in ##c; otherwise, the latter ‘malloc’ will be triggered if the factoid were triggered in another channel.

Similiarily, if there were no malloc factoid in the global namespace, but only in ##c and you attempted to use this factoid in a channel other than ##c, that channel will invoke ##c’s version of malloc, providing that channel doesn’t have its own malloc factoid.

Likewise, if there is a malloc factoid set in ##c++ and the factoid is triggered in the ##c++ channel, then this version of malloc will be called instead of the ##c or the global factoid.

However, if you are in a channel that doesn’t have a malloc factoid and there is no malloc factoid in the global channel, and you attempt to call malloc then the bot will display a message notifying you that malloc is ambiguous and which channels it belongs to so that you may use the fact command to call the correct factoid.

Adding a factoid

factadd

Usage: factadd [channel] <keyword> <description>

To add a factoid to the global channel, use global or .* as the channel. .* is regex-speak for “everything”.

<pragma-> factadd ##c c /say C rocks!

Special commands

/say

If a factoid begins with /say then PBot will not use the <factoid> is <description> format when displaying the factoid.

<pragma-> factadd global hi /say Well, hello there, $nick.
   <PBot> 'hi' added to the global channel
   <prec> PBot, hi
   <PBot> Well, hello there, prec.

/me

If a factoid begins with /me then PBot will ACTION the factoid.

<pragma-> factadd global bounce /me bounces around.
   <PBot> 'bounce' added to the global channel
<pragma-> bounce
        * PBot bounces around.

/call

If a factoid begins with /call then PBot will call an existing command.

<pragma-> factadd global boing /call bounce
   <PBot> 'boing' added to the global channel
<pragma-> boing
        * PBot bounces around.

/msg

If a factoid begins with msg <nick> then PBot will /MSG the factoid text to

Special variables

You can use the following variables in a factoid or as an argument to one.

nick `nick` expands to the nick of the caller.

args `args` expands to any text following the keyword. If there is no text then it expands to the nick of the caller.

arg[n] `arg[n]`expands to the nth argument. Indexing begins from 0 (the first argument is`arg[0]`). You may use a negative number to count from the end; e.g., `arg[-2]` means the 2nd argument from the end. Multiple words can be double-quoted to constitute one argument. If the argument does not exist, the variable and the leading space before it will be silently removed.

arg[n:m] `arg[n:m]`expands to a slice of arguments between`n`and`m`. Indexing begins from 0 (the first argument is`arg[0]`). Not specifying the `m` value means the rest of the arguments; e.g., `arg[2:]` means the remaining arguments after the first two. Multiple words can be double-quoted to constitute one argument. If the argument does not exist, the variable and the leading space before it will be silently removed.

arglen `arglen` expands to the number of arguments provided to a factoid.

channel `channel` expands to the name of the channel in which the factoid is used.

randomnick `randomnick` expands to a random nick from the channel in which the factoid is used.

$0

$0 expands to the original keyword used to invoke a factoid. See also Overriding $0.

adlib list variables

You may create a list of adlib words by using the normal factoid creation method. Multiple words can be surrounded with quotes to constitute one element.

<pragma-> factadd global colors is red green blue "bright yellow" pink "dark purple" orange
    <PBot> colors added to the global channel

Then you can instruct PBot to pick a random word from this list to use in another factoid by inserting the list as a variable.

<pragma-> factadd global sky is /say The sky is $colors.
   <PBot> sky added to the global channel
<pragma-> sky
   <PBot> The sky is dark purple.
<pragma-> sky
   <PBot> The sky is green.

A practical example, creating the RTFM trigger:

<pragma-> factadd global sizes is big large tiny small huge gigantic teeny
   <PBot> 'sizes' added to the global channel
<pragma-> factadd global attacks is whaps thwacks bashes smacks punts whacks
   <PBot> 'attacks' added to the global channel
<pragma-> factadd global rtfm is /me $attacks $args with a $sizes $colors manual.
   <PBot> 'rtfm' added to the global channel
<pragma-> rtfm mauke
        * PBot thwacks mauke with a big red manual.

modifiers

Adlib list variables can accept trailing modifier keywords prefixed with a colon. These can be chained together to combine their effects.

:uc - uppercases the expansion
:lc - lowercases the expansion
:ucfirst - uppercases the first letter in the expansion
:title - lowercases the expansion and then uppercases the initial letter of each word
:<channel> - looks for variable in <channel> first; use global to refer to the global channel

echo $colors:uc RED echo $colors:ucfirst Blue

code-factoids

Code-factoids are a special type of factoid whose text is executed as Perl instructions. The return value from these instructions is the final text of the factoid. This final text is then parsed and treated like any other factoid text.

By default, the variables created within code-factoids do not persist between factoid invocations. This behavior can be overridden by factsetting a persist-key with a unique value.

To create a code-factoid, simply wrap the factoid text with curly braces.

factadd keyword { code here }

Special variables

There are some special variables available to code-factoids.

@args - any arguments passed to the factoid (note that invoker’s nick is passed if no arguments are specified)
$nick - nick of the person invoking the factoid
$channel - channel in which the factoid is being invoked

testargs example

<pragma-> factadd global testargs { return "/say No arguments!" if not @args;
          if (@args == 1) { return "/say One argument: $args[0]!" } elsif
          (@args == 2) { return "/say Two arguments: $args[0] and $args[1]!"; }
          my $results = join ', ', @args; return "/say $results"; }
   <PBot> testargs added to the global channel.
<pragma-> testargs
   <PBot> One argument: pragma-!
<pragma-> testargs "abc 123" xyz
   <PBot> Two arguments: abc 123 and xyz!

rtfm example

Remember that rtfm factoid from earlier? Let’s modify it so that it doesn’t attack Zhivago.

<pragma-> forget rtfm
   <PBot> rtfm removed from the global channel.
<pragma-> factadd global rtfm { return "/say Nonsense! Zhivago is a gentleman and
          a scholar." if $nick eq "Zhivago" or "@args" =~ /zhivago/i; return "/me
          $attacks $args[0] with a $sizes $colors manual." }
   <PBot> rtfm added to the global channel.
<pragma-> rtfm luser
        * PBot smacks luser with a huge blue manual.
<pragma-> rtfm Zhivago
   <PBot> Nonsense! Zhivago is a gentleman and a scholar.

poll example

An extremely basic aye/nay poll system. All code-factoids sharing the same persist-key will share the same persisted variables.

First we add the factoids:

<pragma-> factadd global startpoll { %aye = (); %nay = (); $question = "@args";
          "/say Starting poll: $question" }
   <PBot> startpoll added to the global channel.
<pragma-> factadd global aye { $aye{$nick} = 1; delete $nay{$nick}; "" }
   <PBot> aye added to the global channel.
<pragma-> factadd global nay { $nay{$nick} = 1; delete $aye{$nick}; "" }
   <PBot> nay added to the global channel.
<pragma-> factadd global pollresults { $ayes = keys %aye; $nays = keys %nay;
          "/say Results for poll \"$question\": ayes: $ayes, nays: $nays" }
   <PBot> pollresults added to the global channel.

Then we set their persist-key to the same value:

<pragma-> factset global startpoll persist-key pragma-poll
   <PBot> [global] startpoll: 'persist-key' set to 'pragma-poll'
<pragma-> factset global aye persist-key pragma-poll
   <PBot> [global] aye: 'persist-key' set to 'pragma-poll'
<pragma-> factset global nay persist-key pragma-poll
   <PBot> [global] nay: 'persist-key' set to 'pragma-poll'
<pragma-> factset global pollresults persist-key pragma-poll
   <PBot> [global] pollresults: 'persist-key' set to 'pragma-poll'

And action:

<pragma-> startpoll Isn't this cool?
   <PBot> Starting poll: Isn't this cool?
<pragma-> aye
<luser69> nay
<someguy> aye
<pragma-> pollresults
   <PBot> Results for poll "Isn't this cool?": ayes: 2, nays: 1

Exercise for the reader: extend this poll system to be per-channel using $channel.
Experts: extend this to use a vote <keyword> factoid, and adjust pollresults to show a tally for each keyword.

action_with_args

You can use the factset command to set a special factoid meta-data key named action_with_args to trigger an alternate message if an argument has been supplied.

<pragma-> factadd global snack is /me eats a cookie.
   <PBot> 'snack' added to the global channel
<pragma-> factset global snack action_with_args /me gives $args a cookie.
   <PBot> [Factoids] (global) snack: 'action_with_args' set to '/me gives $args a cookie.'
<pragma-> snack
        * PBot eats a cookie.
<pragma-> snack orbitz
        * PBot gives orbitz a cookie.

add_nick

You can use the factset command to set a special factoid meta-data key named add_nick to prepend the nick of the caller to the output. This is mostly useful for modules.

Deleting a factoid

factrem

forget

To remove a factoid, use the factrem or forget command.

Usage: factrem <channel> <keyword> forget <channel> <keyword>

Viewing/triggering a factoid

To view or trigger a factoid, one merely issues its keyword as a command.

<pragma-> PBot, c?
   <PBot> C rocks!

Viewing/triggering another channel’s factoid

fact

To view or trigger a factoid belonging to a specific channel, use the fact command.

Usage: fact <channel> <keyword> [arguments]

Aliasing a factoid

factalias

To create an factoid that acts as an alias for a command, use the factalias command or set the factoid’s action to /call <command>.

Usage: factalias <channel> <new keyword> <command>

<pragma-> factadd ##c offtopic is /say In this channel, $args is off-topic.
<pragma-> offtopic C++
   <PBot> In this channel, C++ is off-topic.
<pragma-> factalias ##c C++ offtopic C++
<pragma-> C++
   <PBot> In this channel, C++ is off-topic.

<pragma-> factadd ##c book is /me points accusingly at $args, "Where is your book?!"
   <PBot> 'book' added to ##c
<pragma-> book newbie
        * PBot points accusingly at newbie, "Where is your book?!"
<pragma-> factadd ##c rafb /call book
   <PBot> 'rafb' added to ##c
<pragma-> rafb runtime
        * PBot points accusingly at runtime, "Where is your book?!"

Moving/renaming a factoid

factmove

To rename a factoid or move a factoid to a different channel, use the factmove command:

Usage: factmove <source channel> <source factoid> <target channel/factoid> [target factoid]

If three arguments are given, the factoid is renamed in the source channel. If four arguments are given, the factoid is moved to the target channel with the target name.

Changing a factoid

factchange

To change a factoid, use the factchange command:

Usage: factchange <channel> <keyword> s/<pattern>/<change to>/[gi]

<pragma-> c
   <PBot> C rocks!
<pragma-> factchange ##c c s/rocks/rules/
   <PBot> c changed.
<pragma-> c
   <PBot> C rules!

Note that the final argument is a Perl-style substitution regex. See man perlre on your system.

For instance, it is possible to append to a factoid by using: factchange channel factoid s/$/text to append/

Likewise, you can prepend to a factoid by using: factchange channel factoid s/^/text to prepend/

Alternatively, you may append to a factoid by using is also:

<pragma-> PBot, c is also See FAQ at http://www.eskimo.com/~scs/C-faq/top.html
   <PBot> Changed: c is /say C rules! ; See FAQ at http://www.eskimo.com/~scs/C-faq/top.html

factundo

To revert to an older revision, use the factundo command. You can repeatedly factundo a factoid until it has no more remaining undos.

Usage: factundo [channel] <keyword>

factredo

To revert to a newer revision, use the factredo command. You can repeatedly factredo a factoid until it has no more remaining redos.

Usage: factredo [channel] <keyword>

factset

To view or set factoid meta-data, such as owner, rate-limit, etc, use the factset command. See also: factoid metadata list.

Usage: factset <channel> <factoid> [<key> [value]]

Omit <key> and <value> to list all the keys and values for a factoid. Specify <key>, but omit <value> to see the value for a specific key.

Factoid Metadata List

This is a list of recognized factoid meta-data fields. The number in parentheses next to the field is the minimum admin level necessary to modify it; if there is no such number then anybody may modify it.

created_on (90): The timestamp of when the factoid was created.
enabled (10): Whether the factoid can be invoked or not.
last_referenced_in (90): The channel or private-message in which the factoid was last used.
last_referenced_on (90): The timestamp of when the factoid was last used.
modulelauncher_subpattern (90): A substitution expression used to modify the arguments into a command-line.
owner (90): The creator of the factoid.
rate_limit (10): How often the factoid may be invoked, in seconds. Zero for unlimited.
ref_count (90): How many times the factoid has been invoked.
ref_user (90): The hostmask of the last person to invoke the factoid.
type (90): The type of the factoid. “text” for regular factoid; “module” for module.
edited_by (90): The hostmask of the person to last edit the factoid.
edited_on (90): The timestamp of when the factoid was last edited.
locked (10): If enabled, prevents the factoid from being changed or removed.
add_nick (10): Prepends the nick of the person invoking the factoid to the output of the factoid.
nooverride (10): Prevents the creation of a factoid with an identical name in a different channel.
effective-level (20): the effective admin level at which this factoid executes (i.e., for /kick, etc)
persist-key (20): the storage key for allowing code-factoids to persist variables
action_with_args: Alternate action to perform if an argument has been supplied when invoking the factoid.
noembed: Factoid will not be triggered if embedded within a sentence.
interpolate: when set to a false value, $variables will not be expanded.
use_output_queue: when set to a true value, the output will be delayed by a random number of seconds to simulate reading/typing.

factunset

To unset factoid meta-data, use the factunset command.

Usage: factunset <channel> <factoid> <key>

Finding a factoid

factfind

To search the database for a factoid, use the ’factfind` command. You may optionally specify whether to narrow by channel and/or include factoid owner and/or last referenced by in the search.

If there is only one match for the query, it will display that factoid and its text, otherwise it will list all matching keywords.

Usage: factfind [-channel channel] [-owner nick] [-by nick] [-regex] [text]

If you specify the -regex flag, the text argument will be treated as a regex.

<pragma-> factfind cast
   <PBot> 3 factoids match: [##c] NULL casting dontcastmalloc

Information about a factoid

factinfo

To get information about a factoid, such as who submitted it and when, use the factinfo command.

Usage: factinfo [channel] <keyword>

<pragma-> factinfo ##c NULL
   <PBot> NULL: Factoid submitted by Major-Willard for all channels on Sat Jan 1 16:17:42 2005 [5 years and 178 days ago], referenced 39 times (last by pragma- on Sun Jun 27 04:40:32 2010 [5 seconds ago])

factshow

To see the factoid action literal, use the factshow command.

Usage: factshow [channel] <keyword>

<pragma-> factshow ##c hi
   <PBot> hi: /say $greetings, $nick.

factset

To view factoid meta-data, such as owner, rate-limit, etc, use the factset command.

Usage: factset <channel> <factoid> [<key> [value]]

Omit <key> and <value> to list all the keys and values for a factoid. Specify <key>, but omit <value> to see the value for a specific key.

factlog

To see a factoid’s changelog history, use the factlog command.

Usage: factlog [-h] [-t] [channel] <factoid>

-h shows full hostmasks instead of just the nick. -t shows the actual timestamp instead of relative.

<pragma-> factadd hi /say Hello there!
   <PBot> hi added to global channel.
<pragma-> factchange hi s/!$/, $nick!/
   <PBot> Changed: hi is /say Hello there, $nick!
<pragma-> forget hi
   <PBot> hi removed from the global channel.
<pragma-> factadd hi /say Hi!

<pragma-> factlog hi
   <PBot> [3m ago] pragma- created: /say Hi! [5m ago] pragma- deleted [8m ago] pragma- changed to /say Hello there, $nick! [10m ago] pragma- created: /say Hello there!

count

To see how many factoids and what percentage of the database <nick> has submitted, use the count command.

Usage: count <nick>

<pragma-> count prec
   <PBot> prec has submitted 28 factoids out of 233 (12%)
<pragma-> count twkm
   <PBot> twkm has submitted 74 factoids out of 233 (31%)
<pragma-> count pragma
   <PBot> pragma has submitted 27 factoids out of 233 (11%)

histogram

Commands

To see all the currently available commands, use the list commands command.

Some commands are:

Quotegrabs

grab

Grabs a message someone says, and adds it to the quotegrabs database. You may grab multiple nicks/messages in one quotegrab by separating the arguments with a plus sign (the nicks need not be different – you can grab multiple messages by the same nick by specifying a different history for each grab).

You can use the recall command to test the arguments before grabbing (please use a private message).

Usage: grab <nick> [history [channel]] [+ ...] where [history] is an optional argument regular expression used to search message contents; e.g., to grab a message containing the text “pizza”, use: grab nick pizza

    <bob> Clowns are scary.
<pragma-> grab bob clowns
   <PBot> Quote grabbed: 1: <bob> Clowns are scary.

  <alice> Please put that in the right place.
    <bob> That's what she said!
<pragma-> grab alice place + bob said
   <PBot> Quote grabbed 2: <alice> Please put that in the right place. <bob> That's what she said!

<charlie> I know a funny programming knock-knock joke.
<charlie> Knock knock!
<charlie> Race condition.
<charlie> Who's there?
<pragma-> grab charlie knock + charlie race + charlie there
   <PBot> Quote grabbed 3: <charlie> Knock knock! <charlie> Race condition. <charlie> Who's there?

getq

Retrieves and displays a specific grabbed quote from the quotegrabs database.

Usage: getq <quote-id>

rq

Retrieves and displays a random grabbed quote from the quotegrabs database. You may filter by nick, channel and/or quote text.

Usage: rq [nick [channel [text]]] [-c,--channel <channel>] [-t,--text <text>]

delq

Deletes a specific grabbed quote from the quotegrabs database. You can only delete quotes you have grabbed unless you are logged in as an admin.

Usage: delq <quote-id>

recall

Recalls messages from the chat history and displays them with a relative time-stamp.

Usage: recall <[nick [history [channel]]] [-c,channel <channel>] [-t,text,h,history <history>] [-b,before <context before>] [-a,after <context after>] [-x,context <nick>] [-n,count <count>] [+ ...]>

You can use -b/-before and -a/-after to display the messages before and after the result me For example, recall ##c -b 99 would show the last 100 messages in the ##c channel. recall bob 50 -b 5 -a 5 would show the 50th most recent message from bob, including 5 messages before and 5 messages after that message. If you also specify -x <nick>, then the before and after messages will be limited to messages from the <nick> argument; for example, recall -x bob -b 10 would show bob’s 10 most recent messages.

Alternatively, you can use -n/-count to display that many matches resulting from a -h/-history search; for example, recall -h http -n 5 would show the last 5 messages containing “http”. You can specify -x/-context to limit the search to a specific nick; for example, recall -h http -x bob -n 5 would show bob’s last 5 messages containing “http”.

<pragma-> recall alice + bob
   <PBot> [20 seconds ago] <alice> Please put that in the right place. [8 seconds ago] <bob> That's what she said!

Modules

cc

Code compiler (and executor). This command will compile and execute user-provided code in a number of languages, and then display the compiler and/or program output.

The program is executed within a gdb debugger instance, which may be interacted with via the gdb macros described below or with the gdb("command") function.

The compiler and program are executed inside a virtual machine. After each run, the virtual machine is restored to a previous state. No system calls have been disallowed. You can write to and read from the filesystem, provided you do it in the same program. The network cable has been unplugged. You are free to write and test any code you like. Have fun.

Usage

cc [-lang=<language>] [-info] [-paste] [-args "command-line arguments"] [-stdin "stdin input"] [compiler/language options] <code>
cc <run|undo|show|paste|copy|replace|prepend|append|remove|s/// [and ...]>
cc <diff>
[nick] { <same as above without the cc in front> }

You can pass any gcc compiler options. By default, -Wall -Wextra -std=c11 -pedantic are passed unless an option is specified.

The -paste option will pretty-format and paste the code/output to a paste site and display the URL (useful to preserve newlines in output, and to refer to line-numbers).

The -nomain flag will prevent the code from being wrapped with a main() function. This is not necessary if you’re explicitly defining a main function; it’s only necessary if you don’t want a main function at all.

The -noheaders flag will prevent any of the default headers from being added to the code. This is not necessary if you explicitly include any headers since doing so will override the default headers. This flag is only necessary if you want absolutely no headers whatsoever.

The -stdin <stdin input> option provides STDIN input (i.e., scanf(), getc(stdin), etc.).

The -args <command-line arguments> option provides command-line arguments (i.e., argv).

The run, undo, show, replace, etc commands are part of interactive-editing.

The diff command can be used to display the differences between the two most recent snippets.

Supported Languages

The -lang option can be used to specify an alternate compiler or language. Use -lang=? to list available languages.

<pragma-> cc -lang=?
   <PBot> Language '?' is not supported. Supported languages are: bash, bc, bf, c11, c89, c99, clang, clang11, clang89, clang99, clang++, clisp, c++, freebasic, go, haskell, java, javascript, ksh, lua, perl, php, python, python3, qbasic, ruby, scheme, sh, tcl, tendra, zsh

Most, if not all, of these languages have an direct alias to invoke them.

<pragma-> factshow perl
   <PBot> [global] perl: /call cc -lang=perl $args
<pragma-> perl print 'hi'
   <PBot> hi

Default Language

The default language (e.g., without an explicit -lang or -std option) is C11 pedantic; which is gcc -Wall -Wextra -std=c11 -pedantic.

Disallowed system calls

None. The network cable has been unplugged. Other than that, anything goes. Have fun.

Program termination with no output

If there is no output, information about the local variables and/or the last statement will be displayed.

<pragma-> cc int x = 5, y = 16; x ^= y, y ^= x, x ^= y;
   <PBot> pragma-:  no output: x = 16; y = 5

<pragma-> cc #include <sys/utsname.h> struct utsname u; uname(&u);
   <PBot> pragma-:  no output: u = {sysname = "Linux", nodename = "compiler", release = "3.2.0-8-generic", version = "#15-Ubuntu SMP Wed Jan 11 13:57:44 UTC 2012", machine = "x86_64",  __domainname = "(none)"}

<pragma-> cc int a = 2, b = 3;  ++a + b;
   <PBot> pragma-:  no output: ++a + b = 6; a = 3; b = 3

<pragma-> cc sizeof (char)
   <PBot> pragma-:  no output: sizeof (char) = 1

<pragma-> cc 2 + 2
   <PBot> pragma-:  no output: 2 + 2 = 4

Abnormal program termination

If a signal is detected, the bot will display useful information.

< pragma-> cc char *p = 0; *p = 1;
    <PBot> pragma-: Program received signal 11 (SIGSEGV) at statement: *p = 1; <local variables: p = 0x0>

<pragma-> cc void bang() { char *p = 0, s[] = "lol"; strcpy(p, s); }  bang();
   <PBot> pragma-: Program received signal 11 (SIGSEGV) in bang () at statement: strcpy(p, s); <local variables: p = 0x0, s = "lol">

<pragma-> cc int a = 2 / 0;
   <PBot> pragma-: [In function 'main': warning: division by zero] Program received signal 8 (SIGFPE) at statement: int a = 2 / 0;

C and C++ Functionality

Using the preprocessor

Default #includes

These are the default includes for C11. To get the most up-to-date list of #includes, use the cc paste command.

#define _XOPEN_SOURCE 9001
#define __USE_XOPEN
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <math.h>
#include <limits.h>
#include <sys/types.h>
#include <stdint.h>
#include <stdbool.h>
#include <stddef.h>
#include <stdarg.h>
#include <stdnoreturn.h>
#include <stdalign.h>
#include <ctype.h>
#include <inttypes.h>
#include <float.h>
#include <errno.h>
#include <time.h>
#include <assert.h>
#include <complex.h>

Using #include

In C and C++, you may #include <file.h> one after another on the same line. The bot will automatically put them on separate lines. If you do use #include, the files you specify will replace the default includes. You do not need to append a \n after the #include.

<pragma-> cc #include <sys/utsname.h> struct utsname u; uname(&u);
   <PBot> pragma-:  <no output: u = {sysname = "Linux", nodename = "compiler", release = "3.2.0-8-generic", version = "#15-Ubuntu SMP Wed Jan 11 13:57:44 UTC 2012", machine = "x86_64",  __domainname = "(none)"}>

<pragma-> cc #include <stdio.h> #include <stdlib.h> void func(void) { puts("Hello, world"); } func();
   <PBot> pragma-: Hello, World

In the previous examples, only the specified includes (e.g., <sys/utsname.h> in the first example, <stdio.h> and <stdlib.h> in the second, will be included instead of the default includes.

Using #define

You can also #define macros; however, #defines require an explicit \n sequence to terminate, oe the remainder of the line will be part of the macro.

<pragma-> cc #define GREETING "Hello, World"\n puts(GREETING);
   <PBot> pragma-: Hello, World

main() Function Unnecessary

In C and C++, if there is no main function, then a main function will created and wrapped around the appropriate bits of your code (unless the -nomain flag was specified); anything outside of any functions, excluding preprocessor stuff, will be put into this new main function.

<pragma-> cc -paste int add(int a, int b) { return a + b; } printf("4 + 6 = %d -- ", add(4, 6)); int add3(int a, int b, int c)
        { return add(a, b) + c; } printf("7 + 8 + 9 = %d", add3(7, 8, 9));
   <PBot> http://sprunge.us/ehRA?c

The -paste flag causes the code to be pretty-formatted and pasted with output in comments to a paste site, which displays the following:

#define _XOPEN_SOURCE 9001
#define __USE_XOPEN
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <math.h>
#include <limits.h>
#include <sys/types.h>
#include <stdint.h>
#include <stdbool.h>
#include <stddef.h>
#include <stdarg.h>
#include <stdnoreturn.h>
#include <stdalign.h>
#include <ctype.h>
#include <inttypes.h>
#include <float.h>
#include <errno.h>
#include <time.h>
#include <assert.h>
#include <complex.h>
#include <prelude.h>


int add(int a, int b) {
    return a + b;
}

int add3(int a, int b, int c) {
    return add(a, b) + c;
}

int main(void) {
    printf("4 + 6 = %d -- ", add(4, 6));

    printf("7 + 8 + 9 = %d", add3(7, 8, 9));
    return 0;
}

/************* OUTPUT *************
4 + 6 = 10 -- 7 + 8 + 9 = 24
************** OUTPUT *************/

Embedding Newlines

Any \n character sequence appearing outside of a character literal or a string literal will be replaced with a literal newline.

Printing in binary/base2

A freenode ##c regular, Wulf, has provided a printf format specifier b which can be used to print values in base2.

<Wulf> cc printf("%b", 1234567);
<PBot> 000100101101011010000111

<Wulf> cc printf("%#'b", 1234567);
<PBot> 0001.0010.1101.0110.1000.0111

Using the GDB debugger

The program is executed within a gdb debugger instance, which may be interacted with via the following gdb macros.

print

The print() macro prints the values of expressions. Useful for printing out structures and arrays.

<pragma-> cc int a[] = { 1, 2, 3 }; print(a);
   <PBot> pragma-: a = {1, 2, 3}

<pragma-> cc #include <sys/utsname.h> struct utsname u; uname(&u); print(u);
   <PBot> pragma-: u = {sysname = "Linux", nodename = "compiler", release = "3.2.0-8-generic", version = "#15-Ubuntu SMP Wed Jan 11 13:57:44 UTC 2012", machine = "x86_64",  __domainname = "(none)"}

<pragma-> cc print(sizeof(int));
   <PBot> pragma-: sizeof(int) = 4

<pragma-> cc print(2+2);
   <PBot> pragma-: 2 + 2 = 4

ptype

The ptype() macro prints the types of expressions.

<pragma-> cc int *a[] = {0}; ptype(a); ptype(a[0]); ptype(*a[0]);
   <PBot> pragma-: a = int *[1]  a[0] = int *  *a[0] = int

watch

The watch() macro watches a variable and displays its value when it changes.

<pragma-> cc int n = 0, last = 1; watch(n); while(n <= 144) { n += last; last = n - last; } /* fibonacci */
   <PBot> pragma-: n = 1  n = 2  n = 3  n = 5  n = 8  n = 13  n = 21  n = 34  n = 55  n = 89  n = 144

trace

The trace() macro traces a function’s calls, displaying passed and returned values.

<pragma-> ,cc trace(foo); char *foo(int n) { puo, world"); return "Good-bye, world"; } foo(42);
   <PBot> pragma-: entered [1] foo (n=42)  Hello, world  leaving [1] foo (n=42), returned 0x401006 "Good-bye, world"

gdb

The gdb() function takes a string argument which it passes to the gdb debugger and then displays the output if any.

<pragma-> ,cc gdb("info macro NULL");
   <PBot> pragma-: Defined at /usr/lib/gcc/x86_64-linux-gnu/4.7/include/stddef.h:402  #define NULL ((void *)0)

<pragma-> ,cc void foo() { gdb("info frame"); } foo();
   <PBot> pragma-: Stack level 1, frame at 0x7fffffffe660: rip = 0x400e28 in foo (); saved rip 0x400e43 called by frame at 0x7fffffffe680, caller of frame at 0x7fffffffe650 source language c. Arglist at 0x7fffffffe650, args: Locals at 0x7fffffffe650, Previous frame's sp is 0x7fffffffe660 Saved registers: rbp at 0x7fffffffe650, rip at 0x7fffffffe658

Interactive Editing

The cc command supports interactive-editing. The general syntax is: cc [command].

Each cc snippet is saved in a buffer which is named after the channel or nick it was used in. You can use show or diff with a buffer argument to view that buffer; otherwise you can use the copy command to copy the most recent snippet of another buffer into the current buffer and optionally chain it with another command – for example, to copy the ##c buffer (e.g., from a private message or a different channel) and paste it: cc copy ##c and paste.

The commands are: copy, show, diff, paste, run, undo, s//, replace, prepend, append, and remove. Most of the commands may be chained together by separating them with whitespace or “and”.

The commands are described in more detail below:

copy

To copy the most recent snippet from another buffer (e.g., to copy another channel’s or private message’s buffer to your own private message or channel), use the copy command. Other commands can optionally be chained after this command.

Usage: cc copy <buffer> [and ...]

show

To show the latest code in the buffer, use the show command. This command can take an optional buffer argument.

<pragma-> cc show
   <PBot> pragma-: printf("Hello, world!");

This command is stand-alone and cannot be chained with other interactive-editing commands.

diff

To see the differences between the two most recent snippets, use the diff command. This command can take an optional buffer argument.

<pragma-> cc diff
   <PBot> pragma: printf("<replaced `Hello` with `Good-bye`>, <replaced `world` with `void`>");

This command is stand-alone and cannot be chained with other interactive-editing commands.

paste

To paste the full source of the latest code in the buffer as the compiler sees it, use the paste command:

<pragma-> cc paste
   <PBot> pragma-: http://some.random.paste-site.com/paste/results

This command is stand-alone and cannot be chained with other interactive-editing commands.

run

To attempt to compile and execute the latest code in the buffer, use the run command:

<pragma-> cc run
   <PBot> pragma-: Hello, world!

This command is stand-alone and cannot be chained with other interactive-editing commands.

undo

To undo any changes, use undo. The undo command must be the first command before any subsequent commands.

s//

To change the latest code in the buffer, use the s/regex/substitution/[gi] pattern.

<pragma-> cc s/Hello/Good-bye/ and s/world/void/
   <PBot> pragma-: Good-bye, void!
<pragma-> cc show
   <PBot> pragma-: printf("Good-bye, void!");

replace

Alternatively, you may use the replace command. The usage is (note the required single-quotes):

cc replace [all, first, second, ..., tenth, last] 'from' with 'to'

prepend

Text may be prepended with the prepend command:

cc prepend 'text'

append

Text may be appended with the append command:

cc append 'text'

remove

Text may be deleted with the remove command:

cc remove [all, first, second, ..., tenth, last] 'text'

Converts C11 code into English sentences.

Usage: english <C snippet>

<pragma-> english char (*a)[10];  char *b[10];
   <PBot> Let a be a pointer to an array of length 10 of type char. Let b be an array of length 10 of type pointer to char.

<pragma-> english for(;;);
   <PBot> Repeatedly do nothing.

Usage: c99std [-list] [-n#] [section] [search regex]

If specified, section must be in the form of X.YpZ where X and Y are section/chapter and, optionally, pZ is paragraph.

To display a specific section and all its paragraphs, specify just the section without pZ.

To display just a specific paragraph, specify the full section identifier (X.YpZ).

You may use -n # to skip to the nth match.

To list only the section numbers containing ‘search text’, add -list.

If both section and search regex are specified, then the search space will be within the specified section identifier.

Channel Management

chanadd

chanadd adds a channel to PBot’s list of channels to auto-join and manage.

Usage: chanadd <channel>

chanrem

Usage: chanset <channel> [key [value]]

If both key and value are omitted, chanset will show all the keys and values for that channel. If only value is omitted, chanset will show the value for that key.

Channel Metadata List

enabled: when set to a true value, PBot will auto-join this channel after identifying to NickServ (unless general.autojoin_wait_for_nickserv is 0, in which case auto-join happens immediately).
chanop: when set to a true value, PBot will perform channel management (anti-flooding, ban-evasion, etc).
permop: when set to a true value, PBot will automatically op itself when joining and remain opped instead of automatically opping and deopping as necessary.

chanunset

chanunset deletes a channel’s meta-data key.

Usage: chanunset <channel> <key>

chanlist

chanlist lists all added channels and their meta-data keys and values.

ignore

Ignore a user.

Usage: ignore <hostmask regex> [channel [timeout]]

Timeout can be specified as an relative time in English; for instance, 5 minutes, 1 month and 2 weeks, next thursday, friday after next, and so on.

unignore

Unignores a user.

Usage: unignore <hostmask regex> [channel]

whitelist

Whitelists a hostmask to be exempt from ban evasions.

Usages:

whitelist <show/list>
whitelist add <channel> <hostmask>
whitelist remove <channel> <hostmask>

blacklist

Blacklists a hostmask regex from joining a channel.

Usages:

blacklist <show/list>
blacklist add <hostmask regex> [channel]
blacklist remove <hostmask regex> [channel]

ban

Bans a user. If the argument is a nick instead of a hostmask, it will determine an appropriate banmask for that nick.

Usage: ban <nick or hostmask> [channel [timeout]]

If timeout is omitted, PBot will ban the user for 24 hours. Timeout can be specified as an relative time in English; for instance, 5 minutes, 1 month and 2 weeks, next thursday, friday after next, and so on.

unban

Unbans a user. If the argument is a nick instead of a hostmask, it will find all bans that match any of that nick’s hostmasks or NickServ accounts and unban them.

Usage: unban <nick or hostmask> [channel]

kick

Removes a user from the channel. nick can be a comma-separated list of multiple users. If reason is omitted, a random insult will be used.

Usage from channel: kick <nick> [reason] From private message: kick <channel> <nick> [reason]

export

Exports specified list to website.

Usage: export <commands|factoids|quotegrabs|admins|channels>

refresh

Refreshes/reloads PBot core modules and plugins (not the command-line modules since those are executed/loaded each time they are invoked).

sl

Usage: sl <ird command>

<pragma-> sl PRIVMSG #channel :Test message
   <PBot> Test message

die

Kills PBot. :-( Causes PBot to disconnect and exit.

Flood control

PBot can monitor the channel for excessive rapid traffic originating from an individual and automatically ban the offender for a certain length of time.

Message flood

If four (4) or more messages are sent within five (5) seconds, the flood control is triggered. The offender will be muted for 30 seconds for the first offense. Each additional offense will result in the offender being muted for a much longer period. For example, the first offense will result in 30 seconds, the 2nd offense will be 5 minutes, the 3rd will be 1 hour, and so on. The offense counter is decremented once every 24 hours.

The offender will be sent the following private message: “You have been muted due to flooding. Please use a web paste service such as http://ideone.com for lengthy pastes. You will be allowed to speak again in $timeout.”

Join flood

If four (4) or more JOINs are observed within thirty (30) minutes without any messages in between joins, the offender will be forwarded to another channel for a limited time: 2^(number_of_offenses + 2) hours.

In addition to private instructions from PBot, this channel will have a /topic and ChanServ on-join message with instructions explaining to the offender how to remove the forwarding. The instructions are to message PBot with: unbanme.

Any messages sent to the public channel by the user at any time will reset their JOIN counter back to zero. The unbanme command can only be used for the first two offenses – the offense counter is decremented once every 24 hours.

The offender will be sent the following private message: “You have been banned from $channel due to join flooding. If your connection issues have been resolved, or this was an accident, you may request an unban at any time by responding to this message with: unbanme, otherwise you will be automatically unbanned in $timeout.”

Enter key abuse

If four (4) consecutive messages are sent with ten (10) seconds or less between individual messages and without another person speaking, an enter-key-abuse counter is incremented. This counter will then continue to be incremented every two (2) consecutive messages with ten (10) seconds or less in between until another person speaks or more than ten (10) seconds have elapsed, whereupon it returns to requiring four (4) consecutive messages. When this counter reaches three (3) or greater, the offender will be muted using the same timeout rules as message flooding. This counter is automatically decremented once per hour.

The offender will be sent the following private message: “You have been muted due to abusing the enter key. Please do not split your sentences over multiple messages. You will be allowed to speak again in $timeout.”

Nick flood

If four (4) or more nick-changes are observed within thirty (30) minutes, the nick-change flood control is triggered. The offender will be muted for 15 minutes for the first offense. Each additional offense will result in the offender being muted for a much longer period. The offense counter is decremented once every 24 hours.

The offender will be sent the following private message: “You have been temporarily banned due to nick-change flooding. You will be unbanned in $timeout.”

Anti-away/Nick-control

PBot can detect nick-changes to undesirable nicks such as those ending with |away, as well as undesirable ACTIONs such as /me is away.

When such a case is detected, PBot will kick the offender with a link to http://sackheads.org/~bnaylor/spew/away_msgs.html in the kick message.

Anti-auto-rejoin control

PBot can detect if someone immediately auto-rejoins after having been kicked.

When such a case is detected, PBot will kickban the offender (with a kick message of “$timeout ban for auto-rejoining after kick”) for 5 minutes for the first offense. Each additional offense will result in the offender being banned for a much longer period. The offense counter is decremented once every 24 hours.

Opping/Deopping

ChanServ can op and deop PBot as necessary, unless the channel permop meta-data is set to a true value. PBot will wait until about 5 minutes have elapsed before requesting a deop from ChanServ. This timeout can be controlled via the general.deop_timeout registry value, which can be overriden on a per-channel basis.
