KISS for IRC, a tiny IRC client written in POSIX C99.
## Features
* Excellent cross-platform compatibility (due to [POSIX](https://opensource.com/article/19/7/what-posix-richard-stallman-explains) standard compliance).
* No dependencies other than a [C99 compiler](https://en.wikipedia.org/wiki/C99).
* Native [SASL PLAIN and EXTERNAL](https://tools.ietf.org/html/rfc4422) authentication support.
* [TLS/SSL](https://en.m.wikipedia.org/wiki/Transport_Layer_Security) protocol capable (via external TLS utilities).
* Chat history logging.
* Multi-channel joining at server connection.
* Simple shortcut commands and full support for all IRC commands in the [RFC 2812](https://tools.ietf.org/html/rfc2812) standard:
```shell
Send a PRIVMSG to the current channel.
@ Send a message to a specified channel or nick
/ Send command to IRC server (see RFC 2812 for full list).
/# Assign new default message channel.
/? Print current message channel.
```
* Color scheme definition via [ANSI 8-bit colors](https://en.wikipedia.org/wiki/ANSI_escape_code). Therefore, one could theoretically achieve uniform color definition across all shell applications and tools.

## Installation
Building and installing on **KISS Linux** using the Community repository:
```shell
kiss b kirc
kiss i kirc
```
Building and installing on **Arch** and **Arch-based** distros using the AUR:
```shell
git clone https://aur.archlinux.org/kirc-git.git
cd kirc
makepkg -si
```
Building and installing from source (works on **Raspbian**, **Debian**, **Ubuntu** and many other Unix distributions):
```shell
git clone https://github.com/mcpcpc/kirc.git
cd kirc
make
make install
```
## Usage
```shell
usage: kirc [-s hostname] [-p port] [-c channel] [-n nick] [-r real name] [-u username] [-k password] [-x init command] [-w columns] [-W columns] [-o path] [-e|v|V]
-s server address (default: 'irc.freenode.org')
-p server port (default: '6667')
-c channel name(s), delimited by a "," or "|" character (default: 'kirc')
-n nickname (required)
-u server username (optional)
-k server password (optional)
-a PLAIN SASL authentication token (optional, specified with nick)
-e EXTERNAL SASL authentication (optional)
-r real name (optional)
-v version information
-V verbose output (e.g. raw stream)
-o output path to log irc stream
-x send command to irc server after inital connection
-w maximum width of the printed left column (default: '20')
-W maximum width of the entire printed stream (default '80')
```
## Transport Layer Security (TLS) Support
There is no native TLS/SSL support. Instead, users can achieve this functionality by using third-party tools (e.g. stunnel, socat, ghosttunnel).
* _socat_ example:
```shell
socat tcp-listen:6667,reuseaddr,fork,bind=127.0.0.1 ssl::6697
kirc -s 127.0.0.1 -c 'channel' -n 'name' -r 'realname'
```
## PLAIN SASL Authentication
In order to connect using PLAIN SASL authentication, the user must provide the required token during the initial connection. If the authentication token is base64 encoded and, therefore, can be generated a number of ways. For example, using Python, one could use the following:
```shell
python -c 'import base64; print(base64.encodebytes(b"nick\x00nick\x00password"))'
```
For example, lets assume an authentication identity of `jilles` and password `sesame`:
```shell
$ python -c 'import base64; print(base64.encodebytes(b"jilles\x00jilles\x00sesame"))'
b 'amlsbGVzAGppbGxlcwBzZXNhbWU=\n'
$ kirc -n jilles -a amlsbGVzAGppbGxlcwBzZXNhbWU=
```
