My IRC client

Client Features

• Subsequent joins and parts fold into one line and do not scroll chat messages off the screen
• Ignore support that folds ignored messages into the joins and parts. Toggle it off to see previously hidden messages
• Detailed view to see all the messages in a channel in full detail with hostmask and timestamp (F2)
• Nick tab completion
• New message notification
• View ban, quiet, invex, and exception lists
• WYSIWYG mIRC formatting input
• Chanserv integration
• Each user's nick is assigned a consistent color, when a user's nick is rendered in a chat message it uses that same color.
• Support for /STATUSMSG/ messages (messages only voice or op users can see)
• Run commands upon connection
• Ban lists don't obstruct chat messages
• Ban list and user list are searchable
• CERTFP and SASL authentication

TLS

glirc has TLS support via the Haskell tls package. Note that Freenode (and other networks) will allow you to authenticate to NickServ via a client certificate.

I use the x509-store for decoding certificates and private key files. This library seems to support PEM formatted files and does not seem to support encrypted private key files. If the key and certificate are both contained in the certificate file the private key command line argument is unnecessary.

Startup

glirc [FLAGS] INITIAL_NETWORKS...
  -c PATH  --config=PATH  Configuration file path
  -h       --help         Show help
  -v       --version      Show version

Environment variables

USER=<default nickname and username>
IRCPASSWORD=<your irc password>

Configuration file

A configuration file can currently be used to provide some default values instead of using command line arguments. If any value is missing the default will be used.
