    the last version you supplied does not compile here:

    Qt Code: 
    1. elcuco@opensuse:~/src/deveditor> qmake
    2. WARNING: Failure to find: parenmatcher.cpp
    To copy to clipboard, switch view to plain text mode 

    Easy to fix:
    Qt Code: 
    1. elcuco@opensuse:~/src/deveditor> qmake -project -o edit.pro
    To copy to clipboard, switch view to plain text mode 

    Compiles ok, but does not run:

    41. Aborted
    To copy to clipboard, switch view to plain text mode 

    Removing that assert fixes the compilation and the application runs. Much better then previous version.

    My impressions:
    1) wow, that works!
    2) wow... it really works!
    3) damm... it's slow.

    I am running this application on a AMD XP2500 and when I move thr text cursor, I see big spikes of CPU usage. The loading time, is HUGE, since the SH works way to hard on that. Using QRegExp on every line make the code to be colored on a O(N^2) complexity, which is definatly bad for GUI.

    The implementation of "current line" and "breakpoint" are just bad. Marking only part of the line is very wrong, as you pointed already. Nice try, but drop it. IMHO that engine will run faster when you drop it. We must find a solution to this.

    The lines numbering is pretty good, I did not find any problems with it, but even with the older code it worked for me, so I shut up...

    any way... enjoy (screen shot taken on OpenSuSE 10.0), Qt4.1.0 gcc 4.0.2, xorg 6.8.2:

    If you are ditching the QRexExp idea, please look at kate HL definitions. Those syntax are the best ones, they can define anything, since they not define languages but state machines.

    did you notice that prototype of find & replace were already present in the earlier versions?

    my syntax highlighting is working fine but I may have a look at your kate stuff give me somewhere to look for them...

    edit : posted the last version

    nb : it' still a beta but works pretty fine except replace function that is in early developpement state

    Sorry everyone but I removed all attached files because the copyright notice wasn't correct.
    New version is coming soon with right copyright notice, fixed find & replace and improved syntax highlighting ( those who tried the old versions probably noticed that it didn't handle floats)
