Just finished (and published @ npmjs/rexs) my Regex decompiler for REXS. Check out this super complicated regex someone build to parse credit card numbers. I still have no idea how it works, but I can read it now! Gonna work on a webapp for REXS soon, but I'll attach the regex and the compiled output in the thread if anyone wants to figure it out.
I wrote a little language for writing regex @ npmjs.com/rexs. Still need to polish it up a bit and add some better testing, but it works. I'd also like to write a decompiler to understand those multi-line regular expressions people like to write.
