Hi guys !
I’ve been working on an new nice text editor embedded add-on,
for now, only OSX, you can see a screenshot here:
https://github.com/k4rm/ofxCodeEditor
it’s based on Scintilla, which is an opensource editor, so it should work easily on GTK or Win32.
The idea is to split an openframeworks window (using ofxCocoaWindow), so interraction can
be created easily between the opengl/openframeworks view, and the Cocoa one.
See the example included in the example directory.
So… if anyone needs a nice editor ! It should be great for livecoding stuff, etc…
let me know if you have interresting feedback!
