Hi,
I started working on keybindings again for GeanyPy and I was hoping to
get a little advice from the experts.
I've hacked together some code that allows the single GeanyPy plugin to
create new GeanyPlugin structs so that it can add multiple keygroups for
the single plugin. This actually seems to work fairly well considering
how kludgey the implementation is (ie. copying structs from Geanys code
into GeanyPy's code because they aren't exposed, etc.).
Now I have two remaining challenges to overcome. The first is that
there doesn't seem to be a way to remove/delete a keygroup, that is to
undo what plugin_set_keygroup does. The function I think I need is
keybindings_free_group(), but it's not in the plugin API, and I can't
"fake" it like I've done with other parts since it requires the
`keybinding_groups`. So basically what's happening, is when a Python
plugin is unloaded and is cleaned up, I free the "sub" GeanyPlugin and
all it's memory. Now when you go into the Preferences->Keybindings you
see just weird things where the plugin name/keybindings were, presumably
since Geany is reading from freed/adjacent memory or some such.
So the first question is, is there a way to remove a plugin/keygroup
from those registered with Geany? At this point, I don't really care if
it's a kludgey solution, I just want it working :)
The second challenge I'm facing is coming up with a way for GeanyPy to
manage connection of Python plugins keybindings and dispatching to them
when a keybinding is pressed. What I've done so far is, as mentioned
above, to create a phony GeanyPlugin/GeanyKeygroup for each plugin, and
each plugin gets allotted KEYBINDINGS_MAX bindings using the
plugin_set_keygroup() function. The problem I'm having now is how to
associate the Python plugin (consider it a C struct if it helps) with
the keybinding. It seems like it would be easier if there was
possibility of passing a closure or whatever it's called when connecting
to the key binding, but GeanyKeyCallback doesn't seem to support this.
I've a tried and failed so far with a few different ideas. So, can
anyone recommend a decent way of mapping which Python plugin connected
to which keybinding and then call out to the plugin when the keybinding
is activated?
One last thing since I'm already writing a really long email, I notice
in keybindings.h[1] in the GeanyKeyGroup definition, there's a 'plugin'
member that is mentioned elsewhere in keybindings.c (I think) as being
used by GeanyLua or some such. What is this for, and would it be useful
for what I'm trying to do with GeanyPy?
Also, why is the comment above the definition "Plugins should not set
these fields", while the comment for the 'plugin' member says "Used by
plugins"?

Apologies for the really long message, but I'm at a bit of a loss (yet
again).
Cheers,
