Hello!
I'm currently working on patch (not plugin) that may improve current brackets auto-closing. Patch is under construction but I hope for feedback - may be you are interesting in some on those features in geany and may be you have some ideas how to do it better.
Already implemented features. To use it all, enable all brackets completion in preferences.
* auto-complete second char for: {, [, (, ", ' as geany does (rewritten logic) * disable brackets auto-completion inside strings and comments * delete second completed char if you pressed BackSpace * suppress inserting one char twice (if you type "{}" you will get "{}", not "{}}") * wrap selected text into brackets instead of removing selection (select text and type "(" or ")" to wrap selection into "()") * keep selection in cause of wrapping * for C-like languages wrapping selection into "{}" makes auto-indentation (select text and type "{" or "}" - text will be wrapped and indented) * {}-wrapper moves cursor to beginning (before first "{" * for C-like languages to insert {}-block you do not need to select text precisely: geany detects boundaries automatically, just ensure that selection covers lines you need to indent (works like TAB indentation) * fix auto-indent inside {} for C-like languages (makes full indent for this block) * auto-close functions ("sin(|" -> "sin(|);") with double-chars suppression (for C only)
Patch itself and planning features you will find on my github: https://github.com/scriptum/geany-patches/
I also planning to move all brackets logic from editor_notify to GTK's key-press-event because of lack of features in editor_notify events. Is it possible? I tried it and seems that it works fine...
