WIP extensions for miniirc.

Project description


Python 3.5+ Available on PyPI. License: MIT

An extension of miniirc (GitHub, GitLab) that adds more features.

Note that miniirc_extras is alpha-level software and should probably not be used in production.

Some features here may be merged into miniirc eventually.

Loading features

After importing miniirc_extras, features can be loaded with irc.require('feature_name'), and once loaded can be accessed with irc.feature_name.


  • chans: Channel mode tracking, must be loaded while miniirc is disconnected.
  • ensure_connection:
  • mp: (WIP) Multiprocessing handlers for miniirc.
  • testfeature: Debugging
  • users: User tracking, must be loaded while miniirc is disconnected.
  • _json (WIP): Parse JSON messages.


irc.users adds rudimentary user tracking to miniirc.

User objects

User objects store the current user's information and user-defined data, and can be accessed with irc.users[Hostmask] or irc.users['nick'].

The following items are available in User objects:

Variable Description
nick The user's current nickname.
ident The user's current ident.
host The user's current hostname.
realname The user's realname.
hostmask A Hostmask object containing the user's hostmask.
raw_hostmask A string containing nick!user@host.
channels A set containing Channel objects for channels the user is currently in.
account A string containing the user's current NickServ account, or None if the user isn't logged in.

You can also set and get items with strings as keys and JSON-compatible objects as values.

User objects have the following helper functions:

Function Description
msg(*text) Send a PRIVMSG to the user.
me(*text) Send a CTCP ACTION (/me) to the user.
notice(*text) Send a NOTICE to the user.
kick(channel, reason = '') Kicks the user from channel (a string or Channel object).


irc.chans adds channel mode tracking on top of irc.users. You can get channels with irc.chans['#channel-name']

Channel objects

Channel objects have the following attributes:

Variable Description
name The name of the channel.
modes A ModeList object containing a list of modes.
topic The channel topic.
users A set containing User objects for members of this channel.

ModeList objects

ModeList objects store a list of modes, and have the following functions:

Function Description
getbool(mode) Returns True if mode (a single-character string) is set on the corresponding channel. Use this for +i, +t, etc
getstr(mode, default = None) Return the parameter mode was set with, otherwise default. Use this for +k, +l, etc
getset(mode) Return a frozenset containing all the entries stored in mode. If you plan to use this for modes such as +b, you may want to run MODE #channel +b when the bot/client joins the channel to populate the list. Use this for +b, +e, +o, +v, etc
hasstr(mode) Returns True if mode is set with a single parameter, otherwise False.
hasset(mode) Equivalent to len(getset(mode)) > 0.

You can access ModeList objects like dicts, however this will require extra type checking code if you plan to use mypy or another type checker.

Multiprocessing handlers. You can create multiprocessing handlers with and These handlers are called with the limited RestrictedIRC object (a subclass of AbstractIRC) instead of the normal IRC object.

The following functions/variables work with RestrictedIRC:

active_caps, channels, connect_modes, ctcp, debug, ident, ip, ircv3_caps, isupport, me, msg, nick, notice, persist, ping_interval, port, quit_message, quote, realname, ssl, verify_ssl

Trying to modify these variables will result in an AttributeError or the set operation silently failing.

Misc classes


The miniirc_extras.AbstractIRC class provides an easy way to type check IRC objects without stub files.


miniirc_extras adds the abstract-ish class miniirc_extras.Hostmask:

from miniirc_extras import Hostmask

isinstance('test', Hostmask)                    # False
isinstance(('nick', 123, 'host'), Hostmask)     # False
isinstance(('nick', 'user', 'host'), Hostmask)  # True

Hostmask('nick', 'user', 'host') # ('nick', 'user', 'host')
Hostmask(123456, 'user', 'host') # TypeError

Creating new features

This API will probably change in the future.

You can create your own features with miniirc_extras.Feature:

class MyFeature:
    def test_func(self):
        print('test_func called with', self._irc)

    def __call__(self):
        print('MyFeature called with', self._irc)

    def __init__(self, irc):
        self._irc = irc

Once registered, you can require and use it:


irc.feature_name()           # MyFeature called with <miniirc.IRC object>
irc.feature_name.test_func() # test_func called with <miniirc.IRC object>

Miscellaneous functions

Some miscellaneous functions and classes are located in miniirc_extras.utils.

Function Description
DummyIRC(...) A subclass of miniirc.IRC that cannot connect to servers. DummyIRC.__init__ has no required parameters.
dict_to_tags(tags) Converts a dict containing strings and booleans into an IRCv3 tags string. Example: dict_to_tags({'tag1': True, 'tag2': 'tag-data'})b'@tag1;tag2=tag-data '
tags_to_dict(tag_list, separator = ';') Converts a tags list (tag1;tag2=tag-data) joined by separator into a dict containing strings and booleans.
ircv3_message_parser(msg) The same as miniirc.ircv3_message_parser, but also accepts bytes and bytearrays.
hostmask_to_str(hostmask) Converts a Hostmask object into a nick!user@host string.
ircv2_message_unparser(cmd, hostmask, tags, args, *, encoding = 'utf-8') Converts miniirc-style message data into an IRCv2 message encoded with encoding.
ircv3_message_unparser(cmd, hostmask, tags, args, *, encoding = 'utf-8') The same as ircv2_message_unparser, but tags are added.
namedtuple(...) Alias for collections.namedtuple on Python 3.7+, otherwise a wrapper that adds defaults and module keyword arguments.

Note that dict_to_tags and tags_to_dict are available in miniirc as internal functions, however they can and will change.


This is no longer required since miniirc v1.4.0, you can simply add the colon keyword argument to Handlers and CmdHandlers. This function still works, however.

An at-rule to remove the : (if any) from args[-1] when running the handler. This must be placed after @miniirc.Handler.


def handle_privmsg(irc, hostmask, args):
    print(args) # ['#channel', ':Test message']

def handle_privmsg(irc, hostmask, args):
    print(args) # ['#channel', 'Test message']


Allows you to create IRC objects from URLs, for example irc_from_url('irc://nick@ssl-server.example/#channel1,#channel2') will create an IRC object with the nickname nick. Any keyword arguments passed to irc_from_url are sent to IRC().


Allows you to create a group of handlers and apply them in bulk to IRC objects.

Method Description
Handler(...) Adds a Handler to the group, uses the same syntax as irc.Handler.
CmdHandler(...) Adds a CmdHandler to the group, uses the same syntax as irc.CmdHandler.
add_to(irc_or_group) Adds all the handlers in this group to an IRC object or another handler group.
copy() Returns another handler group with the same handlers as this one.


An Enum of most of the IRC numerics in RFC 1459, RFC 2812, and See miniirc_extras/ for a list of numerics and their names.


import miniirc
from miniirc_extras.utils import numerics

@miniirc.Handler(numerics.RPL_WELCOME, colon = False)
def handler(irc, hostmask, args):
    print('Connected to IRC!')

Another example:

>>> from miniirc_extras.utils import numerics
>>> numerics.RPL_ISUPPORT
<numerics.RPL_ISUPPORT: 005>
>>> numerics['RPL_MOTD']
<numerics.RPL_MOTD: 372>
>>> numerics(465)
>>> numerics('422')
<numerics.ERR_NOMOTD: 422>
>>> str(numerics.RPL_YOURHOST)
