It supports python|javascript|sql modes with several themes. It also supports custom language in terms of syntax highlighting, code folding and auto-completion. A custom auto-completer endpoint can be configured for advanced code analysis and IntelliSense.

thanks for this - it looks very nice, and I like the configurability! I am just checking it out now to see if I can use it as a suitable JSON viewer and editor. I have some trouble setting the editor properties, in that the default mode of ‘python’ seems to override my desired ‘mode’ settings. However, the demo that is provided at Document works nicely when changing mode. Any advice?
