notes

The major functionality added in this release includes: - Rootless mode in X11 - Widget Templt

Developer notes for XChat dll's

FIRST: There should be a sample module under the sample directory, this gives a
general overview of writing a module.

#define USE_PLUGIN BEFORE EVERYTHING!

You must include xchat.h and plugin.h from the xchat main directory. Every
module MUST export a function called module_init, it is passed the version
number (an int), a pointer to the module struct for your module and a pointer to
the current session. It returns an int: 0 = success, 1 = fail. The name and desc
parts of the module structure must be filled out with strings.

You must check the version number is what you think it is (currently 2) BEFORE
referencing anthing else.

Any module can hook a signal, using hook_signal and passing a pointer to an
xp_signal struct, filling in the name, callback, naddr and mod parts. Then whenever
that signal is sent, your callback will be called. naddr should be a pointer to
a pointer to a function passed 5 void *'s and a char. At the end of the callback
you use XP_CALLNEXT(naddrfunction, a, b, c, d, e, f) to call the next callback,
a to f being the arg you were passed. Beware that XP_CALLNEXT expands to include
a return. If the chain of callbacks returns a 1 then the normal handler will not
continue. XP_CALLBACK next returns what ever the next callback returns (0 if it
is the last callback) while XP_CALLNEXT_ANDSET returns 1.

A signal callback is passed 5 void *'s and a char (just seemed about
enough), by convention the first void * is a pointer to the session or
server struct. To cast as a signal callback use the define XP_CALLBACK like
a GTK cast.

When the module is removed the module_cleanup function is called, it is passed
the module struct and the current session. You do not have to export a
module_cleanup as ALL COMMANDS AND HOOKS ARE REMOVED BY THE PLUGIN CODE.

Most modules call module_add_cmds at some point, you pass this function a
pointer to a module_cmd_set struct and it install hooks to commands and
messages for you.

See SIGNALS for a list of current signals

To test you module, build it, run xchat and type:

/loaddll /path/to/your/module.so

After this a /listdll should list your module.
