php.sublime-build

{
	"cmd": ["php", "-f", "$file"],
	/* what is this for? */
	"file_regex": ".* in (.*?) on line ([0-9]*)",
	"selector": "source.php"
}

Seriously... what is the file_regex thing for?

Beginning of string
Followed by zero or more spaces (weird syntax on that, btw)
Followed by: File "
Followed by two or more characters (even weirder syntax)
Followed by: ", line
Followed by a number

...so, it's looking for a PHP error message / warning etc. in the output, and then matching the file name and line number, presumably so it can highlight it in the editor.

Slightly more readable would be:

^ *File \"(.{2,}?)\", line ([0-9]*)

Well... it doesn't have anything to do with php (I copied it from the python one) here is the one for ruby: "file_regex": "^(...*?):([0-9]*):?([0-9]*)", which is different apparently... If I knew what it was for, I would probably change it

I think you may be on to something with this "highlighting in the output" thing: https://gist.github.com/1481511

I changed it so it better matches the output from php... I guess?

Speaking of not understanding regex, I forgot the ?.. :P

Edited comment above to add ? and remove insult to former writer of the regex ;)

Right, yes, your version does look better.

It still doesn't seem to affect anything from what I can see

Doh... rtfm http://sublimetext.info/docs/en/reference/build_systems.html

It totally does something, just not when the file is only one line.
