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).
