This bug seems to be specific to the Windows version of KDE (i'm using 4.8.0). When editing a Haskell file, kwrite crashes. This crash is always reproducible (see below). This bug does *not* occur on Ubuntu, KDE 4.8.5. Reproducible: Always Steps to Reproduce: 1. Create new file 2. Save file as "test.hs" 3. type "a" 4. hit return --> crash!
That's... interesting. This is difficult to investigate without a backtrace. Do you get a backtrace you can share with us? It sounds like it could be related to the haskell indenter. If you have a little time to investigate you could try modifying haskell.js (not sure where it gets put on Windows) and see if you can pinpoint what causes the crash. (If the indenter is responsible at all.)
> It sounds like it could be related to the haskell indenter. You're right. I switched off the indenter and the error doesn't occur any more. All other indenters work as well. Unfortunately, the indenter is reset to Haskell every time I save the file :-( I'll investigate this further...
OK, I think I found the reason: Regular expressions don't work! I added the following at the beginning of the indent function: debug("abcdeabc".replace(/a/g, "x")); debug("abcdeabc".search(/a/)); debug("abcdeabc".search(/x/)); and on the console I get (when the indent function is called): abcdeabc -1 -1 instead of xbcdexbc 0 -1 what would be expected. I added the same lines to the script on Ubuntu, and the console output is as expected. So the cause seems to be somewhere in the JavaScript engine... What engine is used by KDE on Windows?
The actual crash occurs when executing the following code: currentLine.stripWhiteSpace().startsWith("|") startsWith uses regular expressions and also uses the escape function, which relies on regular expressions as well and doesn't work either.
I tried editing Haskell files on a windows 7, 32 bit system, and the bug didn't occur. On windows 8, 64 bit, the bug *does* occur. Maybe it has something to do with the OS? Or that the system is 64 bit? Does anybody have an idea why regular expressions in javascript work on the first system, but not on the other?
