When testing an answer for another user's question I found something I don't understand. The problem was to replace all literal \t \n \r characters from a string with a single space. Now, the first pattern I tried was: /(?:\\[trn])+/ which surprisingly didn't work. I tried the same pattern in Perl and it worked fine. After some trial...
I have preg_match_all('/[aäeëioöuáéíóú]/u', $in, $out, PREG_OFFSET_CAPTURE); If $in = 'hëllo' $out is: array(1) { [0]=> array(2) { [0]=> array(2) { [0]=> string(2) "ë" [1]=> int(1) } [1]=> array(2) { [0]=> string(1) "o" [1]=> int(5) } } } The position of o should be 4. I've read about this problem on...
In some obscure situations a regular expression like "/^match/" works in the exact oposite way matching a line that is "something else", and the only way to fix it is to put the whole regex inside braces ... "/^(match)/", why is that happening? ...

I am trying to match a series of text strings with PCRE on PHP, and am having trouble getting all the matches in between the first and second. If anyone wonders why on Earth I would want to do this, it's because of Doc Comments. Oh, how I wish Zend would make native/plugin functions to read Doc Comments from a PHP file... The following...
Is there a way for PCRE regular expressions to count how many occurrences of a character it encounters (n), and to stop searching after it has found n occurrences of another character (specifically { and }). This is to grab code blocks (which may or may not have code blocks nested inside them). If it makes it simpler, the input will be...
Regular expressions can become quite complex. The lack of white space makes them difficult to read. I can't step though a regular expression with a debugger. So how do experts debug complex regular expressions? ...

I have two string variables which are both file paths. The code that worked used ereg which is deprecated, so I'm trying to rewrite it using preg_match: Old code that worked: $path1 = quotemeta($path); ereg("$path1(.*)$", $path2, $matches); Using preg_match which doesn't seem to work: $path1 = quotemeta($path); preg_match("/$path1(....

Is there a way to obtain the C++ equivalent of Perl's PREMATCH ($`) and POSTMATCH ($') from pcrecpp? I would be happy with a string, a char *, or pairs indices/startpos+length that point at this. StringPiece seems like it might accomplish part of this, but I'm not certain how to get it. in perl: $_ = "Hello world"; if (/lo\s/) { $...
