Hi Vimmers, During the development of the new regexp, one thing confuses me a lot: ordered alternation. (e.g. given r.e. 'ab\|abc' and text 'abc', 'ab' matched, not 'abc')
I know that 100% compatibility is one of the project goals. So I try to keep this feature in the new regexp. But the problem is, ordered alternation is kind of 'side effect' of the original back track regexp matcher. AFAIK, It is very hard to implement this feature in the new, truly NFA matcher, if it is not impossible. We can resort to the original regexp when we see '\|', but we don't solve the problem perfectly. So does anyone really need this feature to be kept? If so, please do tell me. For me, the removal of this 'feature' won't break anything. Thanks, Xiaozhou --~--~---------~--~----~------------~-------~--~----~ You received this message from the "vim_dev" maillist.
