Hi Jason and all, Unfortunately from my experience, Rebol is not fast enough for "realtime parsing" even 10Kb script on 600Mhz machine. Some time ago I tried to make text editor with syntax highliting and to tell the truth, I wasn't succesfull. I spent lots of hours, tried several techniques and rewrote the code many times from scratch, but in every case I hit the speed the result of all my efforts was just colored-text viewer. For a good text colored editor we probably need low-level support for colorizing the text directly built in 'face. But the problem is not only in color, also parsing the text for additional features such folding , syntax correction, tap completition and lots of other cool features I'm used from other editors is very time consuming tasks for rebol's parser.(especially when you are working with more than 3Kb text file) All this is just my personal opinion from my Rebol programming exeprience in this field. Maybe someone else has better results or knowledge so don't blame me for that ;-) Anyway, I'd like to know your thoughts... regards, Cyphre
