Rulex – A new, portable, regular expression language
Interesting. It's very similar to a regex language I created for byte-oriented regular expressions [0]
Similar usability principles: delimitated strings, ignore whitespace, and comments.

Knuth-Morris-Pratt string-searching algorithm: DFA-less version
That was a fun read, I liked the use of cmbc to validate the algorithm.
For those who are interested, there's a good tool to specifically test string matching algorithms here:
https://github.com/smart-tool/smart
There are so many string matching algorithms now, with different best and worst cases. Some work better on low alphabets (eg DNA), so are better for text or high entropy data, some take advantage of CPU instructions, some are generic. The real challenge is picking the right algorithm.
I've implemented a few of them in java here, and extended them to support multi byte matching at any position:
