=====
:compact-option:
The unethical IRC trinity. This project consists of an experimental IRC client,
daemon, and bot. It's all you're ever going to need for chatting, as long as
you can make do with minimalist software.
All of them have these potentially interesting properties:
- full IPv6 support
- TLS support, including client certificates
- lean on dependencies (with the exception of 'degesch')
- compact and arguably easy to hack on
- permissive license
degesch
-------
The IRC client. It is largely defined by being built on top of GNU Readline
that has been hacked to death. Its interface should feel somewhat familiar for
weechat or irssi users.
This is the largest application within the project. It has most of the stuff
you'd expect of an IRC client, such as being able to set up multiple servers,
a powerful configuration system, integrated help, text formatting, CTCP queries,
automatic splitting of overlong messages, autocomplete, logging to file,
auto-away, command aliases and rudimentary support for Lua scripting.
kike
----
The IRC daemon. It is designed to be used as a regular user application rather
than a system-wide daemon. If all you want is a decent, minimal IRCd for
testing purposes or a small network of respectful users (or bots), this one will
do it just fine.
Notable features:
- TLS autodetection (why doesn't everyone have this?), using secure defaults
- IRCop authentication via TLS client certificates
- epoll/kqueue support; this means that it should be able to handle quite
a number of concurrent user connections
- partial IRCv3 support
Not supported:
- server linking (which also means no services); I consider existing protocols
for this purpose ugly and tricky to implement correctly; I've also found no
use for this feature yet
- online changes to configuration; the configuration system from degesch could
be used to implement this feature if needed
- limits of almost any kind, just connections and mode `+l`
ZyklonB
-------
The IRC bot. It builds upon the concept of my other VitaminA IRC bot. The main
characteristic of these two bots is that they run plugins as coprocesses, which
allows for enhanced reliability and programming language freedom.
While originally intended to be a simple rewrite of the original AWK bot in C,
it fairly quickly became a playground, and it eventually got me into writing
the rest of the package.
It survives crashes, server disconnects and timeouts, and also has native SOCKS
support (even though socksify can add that easily to any program).
Packages
--------
Regular releases are sporadic. git master should be stable enough. You can get
a package with the latest development version from Archlinux's AUR, or from
openSUSE Build Service for the rest of mainstream distributions. Consult the
list of repositories and their respective links at:
https://build.opensuse.org/project/repositories/home:pjanouch:git
Building
--------
Build dependencies: CMake, pkg-config, help2man, awk, sh, liberty (included) +
Runtime dependencies: openssl +
Additionally for degesch: curses, libffi, lua >= 5.3 (optional),
readline >= 6.0 or libedit >= 2013-07-12
$ git clone --recursive https://github.com/pjanouch/uirc3.git
$ mkdir uirc3/build
$ cd uirc3/build
$ cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug \
-DWANT_READLINE=ON -DWANT_LIBEDIT=OFF -DWANT_LUA=ON
$ make
To install the application, you can do either the usual:
# make install
Or you can try telling CMake to make a package for you. For Debian it is:
$ cpack -G DEB
# dpkg -i uirc3-*.deb
Note that for versions of CMake before 2.8.9, you need to prefix `cpack` with
`fakeroot` or file ownership will end up wrong.
Usage
-----
'degesch' has in-program configuration. Just run it and read the instructions.
For the rest you might want to generate a configuration file:
$ zyklonb --write-default-config
$ kike --write-default-config
After making any necessary edits to the file (there are comments to aid you in
doing that), simply run the appropriate program with no arguments:
$ zyklonb
$ kike
'ZyklonB' stays running in the foreground, therefore I recommend launching it
inside a Screen or tmux session.
'kike', on the other hand, immediately forks into the background. Use the PID
file or something like `killall` if you want to terminate it. You can run it
as a `forking` type systemd user service.
Client Certificates
-------------------
'kike' uses SHA1 fingerprints of TLS client certificates to authenticate users.
To get the fingerprint from a certificate file in the required form, use:
$ openssl x509 -in public.pem -outform DER | sha1sum
Custom Key Bindings in degesch
------------------------------
The default and preferred frontend used in 'degesch' is GNU Readline. This
means that you can change your bindings by editing '~/.inputrc'. For example:
....
# Preload with system-wide settings
$include /etc/inputrc
# Make M-left and M-right reorder buffers
$if degesch
"\e\e[C": move-buffer-right
"\e\e[D": move-buffer-left
$endif
....
Consult the source code and the GNU Readline manual for a list of available
functions. Also refer to the latter for the exact syntax of this file.
Beware that you can easily break the program if you're not careful.
