What Ted is suggesting is more or less what the Cornell Synthesiser Generator was designed for; give it a lexis and an attribute grammar and it'll build you a lexer, parser and structure editor. (I once supervised a student implementing an analogue of the CSG in a higher- order persistent programming language; it worked but you had to be rather patient waiting for the lexer optimizer to do its thing, and the GUI primitives available for the editor were a bit spartan). I am not too sure how much I'd like to work with ABC in a structure editor. I've only used two of those, loved one (Steven Vickers' Forth for the Z80-based Jupiter Ace) and hated the other (a Dutch Pascal- meets-Logo programming language called ABC with a horrendously self- righteous Dijkstroid built-in methodology that made restructuring your code a nightmare). Is the CSG still around? Anybody else out there used it? =================== <http://www.purr.demon.co.uk/jack/> =================== To subscribe/unsubscribe, point your browser to: http://www.tullochgorm.com/lists.html
