PyLink IRC Services

PyLink is an extensible, plugin-based IRC services framework written in Python. It aims to be:

a replacement for the now-defunct Janus.
a versatile framework and gateway to IRC.

Support

First, MAKE SURE you’ve read the FAQ!

When upgrading between major versions, remember to read the release notes for any breaking changes!

Please report any bugs you find to the issue tracker. Pull requests are open if you’d like to contribute, though new stuff generally goes to the devel branch.

You can also find support via our IRC channels: #PyLink @ irc.overdrivenetworks.com(webchat) or #PyLink @ chat.freenode.net. Ask your questions and be patient for a response.

Installation

Installing from source

First, make sure the following dependencies are met:

Python 3.4+
Setuptools (pip3 install setuptools)
PyYAML (pip3 install pyyaml)
ircmatch (pip3 install ircmatch)
For the servprotect plugin: expiringdict (install this from source; installation is broken in pip due to mailgun/expiringdict#13)

Clone the repository: git clone https://github.com/GLolol/PyLink && cd PyLink
Pick your branch.

By default you’ll be on the master (stable) branch, which is bugfix only for the most part (except when a new stable release is introduced).
However, new features or more intensive bug fixes may not always be included. Instead, the devel (pre-release) branch is where active development goes, and it can be accessed by running git checkout devel in your Git tree.

Install PyLink using python3 setup.py install (global install) or python3 setup.py install --user (local install)

Note: --user is a literal string; do not replace it with your username.
Whenever you switch branches or update PyLink’s sources via git pull, you will need to re-run this command for changes to apply!

Installing via PyPI (stable branch only)

Make sure you’re running the right pip command: on most distros, pip for Python 3 uses the command pip3.
Run pip3 install pylinkirc to download and install PyLink. pip will automatically resolve dependencies.
Download or copy https://github.com/GLolol/PyLink/blob/master/example-conf.yml for an example configuration.

Configuration

Rename example-conf.yml to pylink.yml (or a similarly named .yml file) and configure your instance there. Note that the configuration format isn’t finalized yet - this means that your configuration may break in an update!
Run pylink from the command line. PyLink will load its configuration from pylink.yml by default, but you can override this by running pylink with a config argument (e.g. pylink mynet.yml).

Supported IRCds

Primary support

These IRCds (in alphabetical order) are frequently tested and well supported. If any issues occur, please file a bug on the issue tracker.

charybdis (3.5+) - module ts6
InspIRCd 2.0.x - module inspircd
- For vHost setting to work, m_chghost.so must be loaded.
- Supported channel, user, and prefix modes are negotiated on connect, but hotloading modules that change these is not supported. After changing module configuration, it is recommended to SQUIT PyLink to force a protocol renegotiation.
Nefarious IRCu (2.0.0+) - module nefarious
- Note: Both account cloaks (user and oper) and hashed IP cloaks are optionally supported (HOST_HIDING_STYLE settings 0 to 3). Make sure you configure PyLink to match your IRCd settings.
UnrealIRCd 4.x - module unreal
- Linking to UnrealIRCd 3.2 servers is only supported when using an UnrealIRCd 4.x server as a hub, with topology such as pylink<->unreal4<->unreal3.2. We nevertheless encourage you to upgrade so all your IRCds are running the same version.

Extended support

Support for these IRCds exist, but are not tested as frequently and thoroughly. Bugs should be filed if there are any issues, though they may not always be fixed in a timely fashion.

Elemental-IRCd (6.6.x / git master) - module ts6
InspIRCd 3.0.x (git master) - module inspircd
IRCd-Hybrid (8.2.x / svn trunk) - module hybrid
- Note: for host changing support and optimal functionality, a service{} block / U-line should be added for PyLink on every IRCd across your network.
ircd-ratbox (3.x) - module ratbox
- Host changing is not supported on ircd-ratbox.
- On ircd-ratbox, all known IPs of users will be shown in /whois, even if the client is a cloaked relay client: if you’re paranoid about this, turn off Relay IP forwarding by setting the relay_no_ips option in the ratbox network’s server: block.
juno-ircd (11.x / janet) - module ts6 (see configuration example)

Other TS6 and P10 variations may work, but are not officially supported.

Clientbot

Since v1.0, PyLink supports connecting to IRCds as a relay bot and forwarding users back, similar to Janus’ Clientbot. This can be useful if the IRCd a network used isn’t supported, or if you want to relay certain channels without fully linking with a network.

For Relay to work properly with Clientbot, be sure to load the relay_clientbot plugin in conjunction with relay.
