I’m not sure why this regex will not compile in python 2.7 (re.compile). The re.debug flag won’t even show me why.

\b(?<case>(review|case|bug[zs]?(\s| )*(id)?:?)s?(\s| )*([#:; ]| )+)((([ ,:;#]|and)*)(?<bugid>\d+))+

    Because in Python, named captures are done with (?P<name>), not (?<name>). Try:

    \b(?P<case>(review|case|bug[zs]?(\s| )*(id)?:?)s?(\s| )*([#:; ]| )+)((([ ,:;#]|and)*)(?P<bugid>\d+))+

    Be sure to also use a raw string, e.g. r'regex' (which compares with C#’s @"regex" syntax).

    Note that (\s| ) is redundant, and can be replaced with (\s) or simply \s if the capture is not important. Similarly, ([#:; ]| ) can be safely replaced with ([#:; ]).
