  Hi Sanel.

Is there a way to dynamically change the modes ? Or even the scheme from lite to dark ?
For example, one may decide to load the file via a string. When this happens - the loadfile() code is not used and the styletable is not loaded. 
The ability to set the styletable (modes) and change schemes dynamically is useful.

Only modified parts.

Styletable is loaded and set when file extension is detected, based on
mode rules [1].

Modes are similar to Emacs modes - script files with custom keywords and
colors/faces for those keywords (eg. for c++ files [2]).

Faces are abstracted from color values (face is actually color + font +
font size) so creating new themes is fairly trivial. Here is example how
dark theme is defined [3].

Best,
