Hi there,  
  
I’m trying to set up an issue connector for our Fogbugz system and have some problems with the regular expression. Our subversion checkin comments always start with “BUG {casenumber}:” or “IMP {casenumber}:” and I’d like to extract the case number from the comments. The comments may have multiple lines with multiple case numbers.  
  
So far I set up this regular expression:  
  
(?i)[(IMP|BUG|BUGFIX)] (?\d+)  
  
This works in most cases but it also validates with Subversion’s default merge comments. From

Merged revision(s) 10794-10808 from trunk

the 10794 is extracted as an id. Am I missing something?  
  
Regards

I got it working with some help of two colleagues. We changed the regular expression to  
  
(?i)(?:IMP|BUG|BUGFIX) (?\d+)

Hi Kay,  
  
Great that you worked it out. The square brackets matches any of the characters within, so this was matching the ) in "Merged revision(s) 10794-10808 from trunk."  
  
Just a note for anyone looking at this, the forum was not showing the full regex. It should be as follows:

`(?i)(?:IMP|BUG|BUGFIX) (?<``id``>d+)`
