QCodeEdit

QCodeEdit is not so much a text editor as it is a text editing framework.

Indeed, it comes as a library (whose API closely match that of QTextEdit to ease porting) that can easily be linked to or embedded into another Qt application.

A demo application is however provided and while being minimalistic it is already a decent text editor.

Main features :
* speed : by rewriting the document and editor components from scratch, it has been possible to outrank QTextDocument/QTextEdit (by orders of magnitude in some areas)
* low memory usage : again, dropping QTextDocument allowed a lot of improvements
* Unicode/Bidi support : by falling back to QTextLayout when encountering text that requires Bidi processing, QCodeEdit keeps these essential features
* generic syntax engine : highlighting, brace matching, auto-indenting and code folding come for free, or almost. All it takes is to write a small syntax file (in a hierarchical human-readable and well-documented XML format) and a dozen are provided by default.
* flexible UI : a system of panel allow easy extension of editor functionalities. Builtin panels include line number, fold indicators, line marks, line changes, status and inline search.
* unlimited undo/redo
* dynamic line wrapping (that does not reduce performance, contrary to what happens in many editors)
* extended and easy to use search facilities
* easy line marks management
* straightforward line endings management
* straightforward encodings management
* column selection and column edit
* infrastructure to plug completion engines and input bindings
* code snippets
* session save/restore (reload files, cursor position, selection, line marks...)

2.2.3 :
* many bugfixes, mostly in syntax engine
* cleaned code snippets and moved them from the example app to the library
* implemented placeholder affectors (not currently used by snippets though)
* added session management

2.2.2 :
* various bugfixes
* polished the search panel
* added the possibility to easily bind a format file per language
* added a format configuration widget (similar to that of Kate/KWrite)
* added a Designer plugin


2.2.1 : fixes a couple of platform-specific issues (mostly windows ones) introduced by late fixes made during the packaging process.
