With the update to vim 7.4, it seems as if this particular regex just doesn't match in particular cases in 7.4, but it worked fine in 7.3.
syntax region jsRegexpString start=+\(\(\(return\|case\)\s\+\)\@<=\|\(\([)\]"']\|\d\|\w\)\s*\)\@<!\)/\(\*\|/\)\@!+ skip=+\\\\\|\\/+ end=+/[gimy]\{,4}+ contains=jsSpecial,jsRegexpCharClass,jsRegexpGroup,@jsRegexpSpecial,@htmlPreproc oneline Does not match in 7.4, but did in 7.3: var x = /test/; Matches in 7.4 and 7.3: return /test/; I am posting in here in case there is a simple quickfix that I am overlooking. Otherwise I can attempt to put together a more reproducible test case. Cheers, Amadeus -- -- You received this message from the "vim_dev" maillist. Do not top-post!
