matchlen may be wrong

[xavieryin]

int match_len;
char* s = "aa";
char* p = ".*a.*a";
int match_idx = re_match(p, s, &match_len);

expected: match_len == 2
result: match_len == 3

Is anyone also facing this problem?
Or am I doing something incorrectly?

Yes, I did. I had the same result as you.
And in the next pattern and string, returns length=5.

pattern = ".*a.+a"
string = "aaa"

Quick note: tried #63 , but no luck

[xavieryin]

no luck by applying #61

Hi,

I'm not sure if this is the same issue, but I'm matching "\n\n+" in a simple text file (looking for multiple-newline separated paragraphs, and I noticed that matchlen was actually counting every \n that it came across rather than just the number of them actually matching the pattern.

The fix is simple ... in re_matchp() matchlen is not zero'd when you get a matchpattern() failure. I simply added a "*matchlength = 0" as the last line in the do/while loop and it seems to be working perfectly ... I will do some more testing.

Regards,

Lee.
