Hello,
based up on Matthew's fine GtkActions branch [1] I think we could realistically rewrite keybindings.c use GtkAction/accelerators properly.
Currently it re-implements lots of gtk stuff, such as the actual looping through the known keybindings for the callback when a keybinding pressed. When this would be rewritten keybindings.c could probably be half as large (in LOC terms).
The advantage of doing so would be that plugins could register keybindings simply by providing a GtkAction instance (and optionally a GtkMenuItem) instead of a plain callback. This would enable to handle keybindings in a more natural (from a glib/gtk POV) form through signals. This is especially interesting for non-C plugins because it easier to support/implement a gobject-based API then a function-pointer-based one. This is the major reason I'm interested in this.
I think it is possible to do this without breaking the API or at least without actual damage because plugins don't use the fields of GeanyKeyGroup and GeanyKeyBinding so we can change these structs.
Is such a rewrite desirable, and would it have a realistic chance of getting merged? I'm asking because I don't want to spend time on this and never get it merged. Otherwise I would volunteer to do this.
Best regards.
