Why? Irssi supports Perl scripting in its core. However I am a fan of the Tcl language, and I've written many IRC related scripts for the Eggdrop IRC bot. With some effort, you can even update Eggdrop scripts to run on Irssi.
It also solved a particular problem I had where I wanted to easily use non-blocking I/O, such as for HTTP requests. Tcl supports this pattern very easily through its event loop. This makes using Tcl through this module an easy way to talk to HTTP servers.
The module works by loading a Tcl interpreter into Irssi. You can use th
command to interact with this interpreter. The module also supports loading
I've written a number of scripts using this module. You can find them in this repository.
Another is irssi-strava.
To build the module you need:
- Irssi and Irssi development files
- Debian packages: irssi irssi-dev
- glib2 and glib2 development files
- Debian packages: libglib2.0-0 libglib2.0-dev
- Tcl 8.5+ and Tcl 8.5+ development files (8.5 and 8.6 both work).
- Debian packages: tcl8.5-dev tcl8.5
- GNU Make (gmake)
- Debian packages: build-essential (well this will get Make among other things)
It's possible it will work with older Tcl versions, but I haven't tested this.
These commands must be run in the
gmake -f Makefile.FreeBSD
Didn't work? If building fails, check the included (
-I) directories listed in
the Makefile actually exist. They may be at a different location on your system
(such as in
/usr/local/lib). You will need to alter
them until they are all correct if they are not. Feel free to ask me for help.
Building with debug (which only really alters script/module paths right now):
make -e DEBUG=-DDEBUG
make -f Makefile.FreeBSD install
The install will place
~/.irssi/modules and Tcl scripts into
Alternatively you can manually copy
libtcl.so where you would like it.
However, the module always looks in
~/.irssi/tcl for scripts.
To load the module in Irssi:
To autoload the module at startup of Irssi:
echo "load tcl" >> ~/.irssi/startup
The scripts that are loaded automatically are listed in
Alternatively, a script in
~/.irssi/tcl/ can be loaded via
/tcl load_script name_of_script.tcl
Run a command in the Tcl interpreter:
/tcl <command ...>
Reload Tcl scripts:
/tcl set a [expr 5+5] 13:53 -!- Tcl: Running /tcl: 'set a [expr 5+5]' 13:53 -!- Tcl: Result: 10 /tcl set a 13:53 -!- Tcl: Running /tcl: 'set a' 13:53 -!- Tcl: Result: 10
See the "tcl" section in Irssi's
/set for individual Tcl script settings.
