Description:

This is a simple application to test QRegExps. It shows you the captured strings and their respective substrings.

You find the latest stable version of QRegExp-Editor on our project page at http://sourceforge.net/projects/qregexp-editor. Bug-reports and feature requests should be made there. The repository is hosted on gitorious: http://gitorious.org/qregexp-editor/qregexp-editor.

 Just a feedback

Your app is very nice, but i just found the way to make it freeze. Looks like that any regex with '?' freezes the application totally.

Beside that, good job.

 Need more info on the crash

Hi,
thanks for the feedback. Unfortunately you didn't provide enough information for me to reproduce the crash. I've just tested this text:
5.3cm 422inch 76 89.3
21.256 3.4CM

98756456789756746574897456465465.45676MM
8.4?

against this regexp:
(\d+(\.\d+)?)(cm|inch|mm)?(?:\?)?

but this didn't result in a crash even though there are plenty of ? signs in there. Here is the result: http://img17.imageshack.us/img17/223/regexpeditor.jpg

It would be very kind if you provided one or two use-cases where the application crashes on your system (that is the regexp and the parsed text) so I can verify that bug and hopefully debug the app.

Thanks in advance

Hi,
first of all thanks for reporting the bug. The crash is due to your regexp matching the empty string, so a regular expression like [te]? would lead to an infinite loop since it will match 1 or _zero_ occurrences of t or e. Here is a minimal compiling example showing that:

#include <QtCore>
#include <QDebug>

int main()
{
QRegExp rx("[te]?");
QString text("text");
int pos = 0;
int loopCnt = 0;
while((pos = rx.indexIn(text, pos)) != -1) {
Q_ASSERT(loopCnt++ < 10);
qDebug() << "pos:" << pos << " cap(0):" << rx.cap(0) << " len:" << rx.matchedLength();
pos += rx.matchedLength();
}
}

Of course this shouldn't crash this application so I fixed that bug. Now if you happen to match the empty string the application will abort evaluating the regexp and display a warning to make you aware of that.

I'm using the latest git revision.
Using this data:
5.3cm 422inch 76 89.3
21.256 3.4CM

98756456789756746574897456465465.45676MM
8.4?

against this regexp:
(\d+(\.\d+)?)(cm|inch|mm)?(?:\?)?

I got this result:
http://img251.imageshack.us/img251/1020/qregexpeditornoresults.png

no values. clicking on the colored rows doesn't produce any effects.

There is a development mailing list ?

Hi,
unfortunately there is no mailing list since I didn't expect any feedback.

Regarding the issue, I couldn't reproduce it (which does not mean that there is no issue) so it would be kind if you tell me which version of Qt you are using.

I'll change the code and add qDebug() instructions so the matches can be written to the console. That would give us some useful hints as to where to find the bug.

I'll also send you a private message with my email address and messenger ID's so we can debug this together if you like :-).

Best regards
