Hello everybody,
The following code highlights prolog code statically making use of PPTextHighlighter, I leave the code to share with the community since it might be of help to someone else.�
Could someone point out how can this be converted to its dynamic counterpart?; The keystroke handler for�GLMTextPresentation and what model is currently being used for instance to highlight smalltalk code would be very much appreciated.�
Thank beforehand,
Jesus
