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.
From http://bergel.eu/download/Dyla2010/dyla10_submission_4.pdf I know that it might be neccesary a fuzzy highlighter as is written at the end of the code, and it is probably the right object to use but I can not figure out where to plug it.
Thank beforehand, Jesus | text textRenderer textShower | text := 'p(Q,R):-q(R), unify_st(X, smalltalk_code), r(T). q(Q):-d(R). q(Q).'. textRenderer := [ PPTextHighlighter new parser: PPPrologParser new; color: 'small_atom' with: Color blue muchDarker; bold: 'small_atom'; color: 'unify_st' with: Color green muchDarker; bold: 'unify_st'; color: 'string' with: Color gray muchDarker; color: 'number' with: Color gray muchDarker; color: 'boolean' with: Color gray muchDarker; highlight: text asText. ].
