PBot

PBot is a versatile IRC Bot written in Perl

Features

Advanced Interpreter

PBot has an advanced command interpreter with useful functionality.

• piping
• command substitution
• command separation
• inline commands
• $variable interpolation
• aliases
• and more!

Factoids

PBot has factoids with advanced features.

• metadata (e.g. owner, times used, last used date, locked, etc)
• advanced argument processing (indexing, splicing, etc)
• special commands: /say, /me, /msg, /code, etc
• advanced $variable interpolation ($var:lc to lowercase contents, $var:ucfirst to uppercase first letter, etc)
• factoid-based variable lists (e.g., add a factoid $colors containing “red green blue” and then !echo $colors will randomly pick one)
• changelog history
• undo/redo history
• and much, much more!

Code Factoids

Code factoids are a special type of factoid that begin with the /code command.

/code <language> <code>

That’s right! Anybody can create a factoid that can execute arbitrary code in any language! This is one of PBot’s most powerful features.

How is this safe? Because the code is executed within a virtual machine that has been configured to fall-back to a previously saved state whenever it times out.

Modules

PBot can execute any command-line program or script as an internal command. We call these modules.

These are just some of the more notable modules; there are several more:

PBot can dynamically load and unload Perl modules to alter its behavior.

These are some of the plugins that PBot has, there are many more:

PBot has easy admin management via simple built-in commands.

Useful IRC command improvements

• mode command can take wildcards, e.g. mode +ov foo* bar* to op nicks beginning with foo and voice nicks beginning with bar
• unban <nick> and unmute <nick> can remove all bans/mutes matching <nick>’s hostmask or account
• ban and mute will intelligently set banmasks; also supports timeouts
• ban and mute can take a comma-separate list of nicks. Will intelligently group them into multiple MODE +bbbb commands
• kick can take a comma-separated list of nicks

• and much, much, more

Easy configuration

PBot’s settings are contained in a central registry of key/value pairs grouped by sections.

These settings can easily be configured via several methods:

• PBot’s command-line arguments
• simple built-in commands (regset, regunset, etc)
• editing the $data_dir/registry plain-text JSON file
