| Nov 10, 2017 at 5:24 | comment | added | eaglgenes101 | The most powerful "regex" engines out in the open right now have recognition power equal to that of a linear bounded automata. Standard issue regex, pattern recursion, unlimited lookhead, and unlimited lookbehind are all you need for context-sensitive parsing (though backreferences and such generally help with complicating efficient parsing), and some have them all. Don't even get me started on the engines that let you embed code into the regex. | |
