There are many variations possible. I have to admit yours is simpler, although I should note it parses a different language than your original request ("foo=foo=foo=foo=" is considered valid in this version)

BTW, benchmarks have shown using .*?D is slower than [^D]*D (where D is the delimiter).

Also note using [^\\] is not necessary, though harmless (since if the char is a backslash, the \\. will match unless the backslash is end the end, which case there's also no delimiter and the whole pattern will not match).

And finally, in your original you used the /s while you're not using it here.. I don't know if that's deliberate or a mistake, but I thought I'd note it.

•Update: and I just noticed you completely forgot support for the colon-delimiter (although that's not hard to add). Also that (?= \s* | \z ) zero-width assertion is completely futile since it also matches 0 chars (due to the \s*).
