Strange behavior with regex replacing
|
Can't Post
|

Hey guys,
I'm having a weird problem that doesn't make any sense to me. Here's the specific case:
regex: "(.*?y)\s(.*?)"
format: "$1ing $2IN"
input: "study stVdi:"
output: "studying INstVdi:"
The output is screwed up--no matter what I do, $2 is showing up at the end of the string.
It's very much worth noting that I'm actually working in C++ using the Boost library with perl-style matching. But before I go and hassle the regex++ people, I want to make sure that I'm not doing something stupid.
Is there anything wrong with my test case here that would cause this behavior?
EDIT: Scratch that, I figured it out. It only took me three days. :P The second non-greedy match was capturing "", so I just had to remove the ?.
