[Bf-committers] Text Editor - Scintilla Integration

[Justin Dailey]

Hi,

Adding scintilla just for syntax highlighting is overkill, I agree. But that is not why I originally started looking into it. Currently maintaining the text editor functionality can be a pain, especially when it comes to undoing/redoing operations. If blender did use scintilla, then developers only have to worry about the thin layer between Blender and Scintilla, and not the internals. It would also leverage the usefulness of scintilla inside of Blender by having more features if desired. It also has support for advanced features such as autocompletion and calltips.
It is still an early WIP but I think it has alot of potential (plus its been a fun side project for me :-)). Ultimately a decision can be made as to actually use it or not.

Thanks,
Justin
