About

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

These are represented as <section>.<key>. For example, irc.port is set to 6667 by default.

Types of values

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

Creating array values

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

For example, we’ll create a fictional Registry key animals in fictional section foo and then set its type to array.

<pragma-> !regset foo.animals aardvark,badger,cat,dingo
   <PBot> foo.animals set to aardvark,badger,cat,dingo

<pragma-> !regsetmeta foo.animals type array
   <PBot> foo.animals: 'type' set to 'array'

Overriding registry values per-channel

Some Registry items belonging to a specific section may be overridden on a per-channel basis by setting the item in a channel-specific section.

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

Overriding Registry values via command-line

You may override the Registry values via the PBot start-up command-line. Such overrides are permanent and will be saved.

$ ./pbot data_dir=mybot irc.botnick=coolbot irc.server=freenode.net irc.port=6667

Registry commands

regset

regset sets a new registry item or updates an existing item.

Usage: regset <section>.<item> <value>

To override the trigger for #mychannel to $:

<pragma-> !regset #mychannel.trigger $
   <PBot> #mychannel.trigger set to $

To override the trigger for #mychannel to be any of ,, ! or %, you can use a character class:

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

regunset

regunset removes a registry item from a specific section/channel.

Usage: regunset <section>.<item>

regchange

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

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

<pragma-> regset 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!

regshow

regshow displays the type and value of a registry item.

Usage: regshow <section>.<item>

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

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 .*.

regsetmeta

regsetmeta 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: regsetmeta <section>.<item> [key [value]]

For example, this directly sets the value meta-data key of irc.botnick.

 <pragma-> !regsetmeta irc.botnick value candide
         * PBot changed nick to candide
 <candide> irc.botnick: 'value' set to 'candide'

That example is equivalent to regset irc.botnick candide.

regunsetmeta

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

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

Editing Registry file

You may edit the Registry file manually. It is located as $data_dir/registry. Its contents are plain-text JSON.

This is a sample entry:

"irc" : {
  "botnick" : {
     "type" : "text",
     "value" : "PBot"
  }
}

After editing an entry in the Registry file, you may reload it with the reload command.

<pragma-> !reload registry
   <PBot> Registry reloaded.
