I want to do such an editor. Preferrably something fast. And in the current Pharo. There have been several text models, Rubric etc. What is the quickest way to get such a thing? Features: Load/Save content Highlight keywords based on syntax parsing Act on the element under the cursor Act on the element when (modifier)clicking on it (or hovering). Fast (or at least, not sluggish on a "normal" (ie Core i5 1.8Ghz) laptop) This is really something I miss being able to do in Pharo. Lots of code is using "STHStyler" things but there seems to be no easy way to extend that (as it seems to be using the AST or something like that). I am okay with a first easy approach to highlighting, like in Vim where one puts a syntax file with not that many things. Phil
