I don't think this is true. I briefly looked at the jEdit code that manages the syntax highlighting, and it doesn't do multiple passes over the file. It tokenizes a line, if that line contains something that could span multiple lines (like { or (* style comments), it carries the state and context over to the next line. Then it processes the next line etc... only a single pass seems to be used. jEdit also supports code-folding, but I haven't looked at how they tie that into the whole TextEdit component yet. The more I play with jEdit the more impressed I get regarding all it's features and how extensible it is via it's plugin system. A pretty amazing piece of engineering in a very small download (2.5MB). > undo-tracking, and foldable blocks come into play, and UTF-8 and tab > expansion, then it may take longer to retrieve the text to show, the > highlighter must be fault-tolerant to cover temporarily invalid tokens, jEdit supports all that and more, and it is very fast! Like I said, a very impressive piece of engineering. -- Regards, - Graeme - _______________________________________________ fpGUI - a cross-platform Free Pascal GUI toolkit http://opensoft.homeip.net/fpgui/ -- _______________________________________________ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
