Hi:
I need to customize some regex for output capture, I'd like to ask your help:
PHP:
Parse error: syntax error, unexpected T_STRING in Test.php on line 11
(No idea)
GCC:
Test.cpp:21: syntax error before `(' token
%f:%l:(%c:)?.* works for that but not when column is included:
Test.cpp:7:17: Mat.h: No such file or directory

Try this:
.*in %f on line %lGCC:
PN actually has built-in support for GCC error parsing, but this is currently broken in 2.0.9 as I need to change the regexes for the new engine.
To use .9 currently, it's easy enough to fix the regex. The one you reference above expands to this:
(?P<f>.+):(?P<l>[0-9]+):((?P<c>[0-9]+):)? .*Note that the following expansions are done:
%f = (?P<f>.+)
%l = (?P<l>[0-9]+)
%c = (?P<c>[0-9]+)Regular expressions are by default "greedy" which means they'll take as many characters for each match as they can. Because the last match bit is optional, the first reference to [0-9]+: ends up using the last number and colon (so the line number field matches the column in the string). The filename then includes the line number.
Results from your example:
File: Test.cpp:7
Line: 17
Col:
If we make the filename match bit "non-greedy" then it will take as little of the string as it can. With Xpressive (the new regular expressions engine) we do this by adding a question mark to the filename bit:
(?P<f>.+?):(?P<l>[0-9]+):((?P<c>[0-9]+):)? .*The results are now:
File: Test.cpp
Line: 7
Col: 17
