Pragmatic Software 3d97dc2c33 Rename "modules" to "applets" 
"Applet" is a much better name for the external command-line
scripts and programs that can be loaded as PBot commands. They
will no longer be confused with Perl modules.

## 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](#regsetmeta) command to change the `type` [metadata key](#metadata-list) 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. These
overrides are not temporary; they will be saved.
$ ./pbot data_dir=mybot irc.botnick=coolbot irc.server=irc.libera.chat 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 metadata values for a specific registry key. See [registry metadata list](#metadata-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` metadata 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 metadata 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`](../data/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.

### Channel-specific Registry items
All of above section-specific registry items can be overriden on a per-channel
basis if it makes sense for it to be able to do so.
However, some items exist only as a channel-specific item. You must [`regset`](#regset)
these for your channels. They are listed here.
Name | Description
--- | ---
[channel].default_ban_timeout | Overrides general.default_ban_timeout for this channel.
[channel].default_mute_timeout | Overrides general.default_mute_timeout for this channel.
[channel].dont_enforce_antiflood | Disables anti-flood enforcement for this channel.
[channel].max_newlines | The maximum number of lines to be sent before truncating to a paste site, if `preserve_newlines` is enabled.
[channel].no_url_titles | Disables display of URL titles for this channel.
[channel].notyposubs | Disables use of `s//` substitution to edit messages.
[channel].preserve_newlines | If set to a true value, newlines will not be replaced with spaces in this channel. Each line of output will be sent as a distinct message.
[channel].ratelimit_override | Duration, in seconds, of the rate-limit for factoids in this channel. To disable factoid rate-limiting for a channel, you can set this to `0`.
[channel].rejoin_delay | Overrides autorejoin.rejoin_delay for this channel.
[channel].strictnamespace | When enabled, factoids belonging to other channels will not show up in this channel unless specifically invoked.
[channel].trigger | Overrides the bot trigger for this channel.
[channel].typosub_ignore_commands | Do not apply `s//` substitution to bot commands.
[channel].interpolate_factoids | If this key exists and is set to `0` then factoids containing `$variables` will not have the variables expanded and interpolated.
