I think this is a perfect example of a case where the old regex engine SHOULD do better. In this case, you have a bunch of literal matches with very little if any backtracking, and the number of possible matches is so large that there will be many many states added in the new engine, none of which will normally match. Bram, are you still planning on making the automatic selection of regex engine based on which one is probably going to be faster? This might be a good first type of pattern to trigger selection of the old engine. -- -- You received this message from the "vim_dev" maillist. Do not top-post!
