in [TCL]

From: S-Y. Chen on 7 Jan 2010 12:04 I am trying to make my text widget highlighting certain keywords. I search the newsgroup archive and did not find anything easy. Is there a simple way to do this ? Regards S-Y. Chen

Chen One simple solution that works surprisingly well is to put a binding on KeyRelease. Simply search forward and backwards for the start and end of the current word. Look up the word in an array or dict for the color, and apply a tag with that color to the word. It may sound like overkill to do it on every keypress, but it's just a few lines of code that executes in just a few milliseconds.

If it's just keyword highlighting and not syntax highlighting in general then you can simply re-parse the current line and re-hilight the line. It's fast enough. It's what I do for my own code editor.
