If the NFA starts with an assertion, make sure it's true before doing anything else. Also, check for last-state _lookaround_ rather than just last state, before breaking (instead of aborting) when the assertion fails

0de3a94ce3
Fixed bug with lookaheads: f(?=f) would not match anything in 'ffa', because of the 'a' at the end of the string. Fixed by checking if there are other last states when an assertion fails, rather than immediately aborting
2024-11-24 15:04:51 -05:00
fe1136c54c
Fixed bug with parentheses in lookaround regex; fixed bug with reading last line of test string (if it doesn't end in a newline)

Updated TODO

I didn't like the existing capturing group implementation, so I moved
that to a separate branch. This branch does not (at the moment) any code
relating to capturing groups.
