Irken is an attempt to build a small, functional, IRC client in Tcl/Tk. It aims to honor as much of IRC as possible while still remaining small enough to understand by tinkerers.
On startup, if no configuration files are found, a file will be created at ~/.config/irken/irken.tcl with a server entry. Any files ending with .tcl will in the configuration directory will be executed in alphabetical order. Since configuration is done with normal Tcl files, theoretically any customization can be achieved.
Plugins are implemented as Tcl files which are loaded on startup. Typically, a plugin will install hooks to add commands or respond to messages. Hooks are defined with the following command:
When a hook's trigger occurs, each hook is called in order of priority. The hook's handle should be unique, and is used so that the hook may be redefined.
In Irken, triggers are of the form handleMESSAGE, ctcpMESSAGE, or cmdCOMMAND. The priority of the normal irken handling of a hook is 50. These hooks should always execute, since much of the UI depends on them. The priority of normal irken message display is set to 75, so that plugins may block or change messages before they are displayed.
