Hello Vim developers, I've found a discrepancy in pattern matching while re-running my plugins' test suites. With the new NFA-regexp, a (rather complex, generated, used for searching insert mode completion matches) pattern does not match any more:
:echo '__mul__sub__und__everywhere__' =~# '\V\<\%(m\%(_\@!\k\)\*_\@!\|_\*m\k\+\%(_\|\k\&\A\)\@=\)\%(\%(\%(_\@!\U\)\@<=\%(S\&\u\|\%(\k\&\A\)\+s\)\k\*\|_\@<!\%(S\&\u\|\%(\k\&\A\)\+s\)\l\k\*\)\|_\+s\k\+\)\%(\%(\%(_\@!\U\)\@<=\%(U\&\u\|\%(\k\&\A\)\+u\)\k\*\|_\@<!\%(U\&\u\|\%(\k\&\A\)\+u\)\l\k\*\)\|_\+u\k\+\)\%(\%(\%(_\@!\U\)\@<=\%(E\&\u\|\%(\k\&\A\)\+e\)\k\*\|_\@<!\%(E\&\u\|\%(\k\&\A\)\+e\)\l\k\*\)\|_\+e\k\+\)\>' To reproduce, use the attached script: vim -N -u NONE -S bad-re.vim 0 1 This is with a huge build of Vim 7.4a.24, running in an Ubuntu 13.04 x64 VM. See attached bad-re.version for more info. I last ran the test suite successfully with Vim 7.3.1280, so the bug must have been introduced since then. -- regards, ingo -- -- You received this message from the "vim_dev" maillist.
