## Features ## Features
### Useful IRC command improvements ### IRCv3
* [`mode`](doc/Admin.md#mode) command can take wildcards, e.g. `mode +ov foo* bar*` to op nicks beginning with `foo` and voice nicks beginning with `bar` PBot supports several features of the IRCv3 specification.
* `unban <nick>` and `unmute <nick>` will remove all bans/mutes matching their current or previously seen hostmasks or accounts
* [`ban`](doc/Admin.md#banmute) and [`mute`](doc/Admin.md#banmute) will intelligently set banmasks; supports timeouts
* [`ban`](doc/Admin.md#banmute) and [`mute`](doc/Admin.md#banmute) can take a comma-separate list of nicks. Will intelligently group them into multiple `MODE +bbbb` commands
* [`kick`](doc/Admin.md#kick) can take a comma-separated list of nicks; also accepts wildcards
* and much, much more!
For more information, see the [Admin documentation.](doc/Admin.md) * client capability negotiation
* SASL authentication
### Channel management * account-notify, extended-join, and more.
PBot can perform the typical channel management tasks.
* opping/deopping, etc
* channel-mode tracking
* user hostmask/alias tracking
* ban-evasion detection
* flood detection
* whitelisting, blacklisting, etc
* spam/advertisement detection
* and much, much more!
For more information, see the [Channels documentation](doc/Admin.md#channel-management-commands) and the [Anti-abuse documentation](doc/AntiAbuse.md)
### User management
PBot has easy straightforward user management via simple built-in commands.
* [user capabilities](doc/Admin.md#user-capabilities) dictate what users can and cannot do
* user accounts can be global or channel-specific
* users can be recognized by hostmask or required to login with password
* users can adjust their [user-metadata](doc/Admin.md#user-metadata-list) with the [`my`](doc/Commands.md#my) command
* and much, much more!
For more information, see the [Admin documentation.](doc/Admin.md#user-management-commands)
### 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](doc/Registry.md#overriding-registry-values-via-command-line)
* [simple built-in commands (`regset`, `regunset`, etc)](doc/Registry.md#registry-commands)
* [editing](doc/Registry.md#editing-registry-file) the [`$data_dir/registry`](data/registry) plain-text JSON file
For more information, see the [Registry documentation.](doc/Registry.md)
### Reload core modules without disconnecting
Suppose you edit some PBot source file, be it a core file such as PBot/Factoids.pm or
a Plugin such as Plugins/Wttr.pm. Or suppose there's a PBot update available. Most simple
bots would require you to shut down the bot and restart it in order to see the modifications.
Not PBot! Rather than shut PBot down and restart it, you can simply use the [`refresh`](doc/Admin.md#refresh)
command to reload all modified PBot core files and Plugins.
You can also use the [`reload`](doc/Admin.md#reload) command to reload any modified
configuration or data files.
