Visual Studio Regex '?'

MSVS: where is the regex ?

I have code that I am trying to match with a regular expression in MSVS 2008, but I cannot find a regular expression for it. Take the classic example:

colou?r

... which is a regular expression that matches coloror colour. This does not match either MSVS. Referring to the help file, I can not find ?.

This will not be a big problem - it can be emulated with alternation:

colo(u|)r

However, I get “Grouped expression missing”). "... what is it ... no. Strangely enough, MSVS has these alternative groups (I'm not quite sure why ...) with curly braces:

colo{u|}r

" ".... . , ?? , /, (color|colour). , , .

, ...

, , . :

^[A-Z]+\t[0-9]+\t[^\t]+

^[A-Z]+\t[0-9]+\t[^\t]+\t[^\t]+

:

colo(u)|()r

for your real example, this will correspond to each line:

^[A-Z]+:b[0-9]+:b[^\t]+(\t[^\t]+)|()

Have you tried with the longest common path on the right?

For example, for color and color, this would be:

colo(ur|r)

and for your 2 regular expressions it will be:

^[A-Z]+\t[0-9]+\t{[^\t]+|[^\t]+\t[^\t]+}
