I never noticed that... How long is "too long"? And what, if any, syntax highlighting type is active? > How long is "too long"? And what, if any, syntax highlighting type is active?

This problem occurs in the program kile, with lines of about 2k length.
Syntax highlighting ist activated.

Note that Kile uses a different syntax highlighting for LaTeX than the native Kate highlighting. The latex-kile.xml is optimized (in the sense that it uses #pop and $push, reducing the use of the stack) and not significantly slower than the latex.xml file. The latex-kile.xml is located at: http://webcvs.kde.org/cgi-bin/cvsweb.cgi/kdeextragear-2/kile/kile/syntax/latex-kile.xml Checking with a 10.000 character line, I can confirm things are slow. The more syntax highlighting is going on, the slower it gets. latex-kile.xml seems some what slower than latex.xml here. I guess it is because latex-kile.xml is more thorough/complex than latex.xml. However in constructing the 10.000 c line caused Kate to become very laggy, it seems Kate is just not fast when dealing with long lines. Admitted, the line is ridiculously long. best, Jeroen it is a duplicate of #64569 - a known issue, and still slow in CVS HEAD. *** This bug has been marked as a duplicate of 64569 *** Could you provide a sample file? Questions: * does it matter if you type in the beginning, middle or end of the line? * is the file syntax highlighted, and does it help turning that off (setting the syntax highlight to 'normal')? It is not only for very long lines. Kate makes the CPU work 100% when "left"ing (moving right) in a line as long as 147 (editing a bash script of 6 lines). The problem occurs only after around the 10th column (or character). I would not call 147 a huge number. So, something really sucks with Kate. It makes my xmms choke. :( May be related: http://bugs.kde.org/show_bug.cgi?id=93928 |
