before starting to use PhpStorm, I used (and still use) BBEdit on Mac OS X, which supports the “txmt://” URL scheme which was introduced by TextMate. Therefore, I can configure Xdebug like this:
xdebug.file_link_format = "txmt://open?url=file://%f&line=%l"
This will have the effect that whenever Xdebug encounters a problem and displays a callstack, the filenames and line numbers are links which can be clicked to directly get to precise location in the code. Question: is there an URL scheme which is supported by PhpStorm to get this behaviour? If not, it would be a great addition.
