Some people, when confronted with a problem, think “I know, I’ll use regular expressions.” Now they have two problems.

Regular Expressions with Backreferences and Lookaheads Capture NLOG
Backreferences and lookaheads are vital features to make classical regular expressions (REGEX) practical. Although these features have been widely used, understanding of the unrestricted combination of them has been limited. Practically, most likely no implementation fully supports them. Theoretically, while some studies have addressed these features separately, few have dared to combine them. In those few studies, it has been made clear that the amalgamation of these features renders REGEX sig…

A Coq Mechanization of JavaScript Regular Expression Semantics
We present an executable, proven-safe, faithful, and future-proof Coq mechanization of JavaScript regular expression (regex) matching, as specified by the last published edition of ECMA-262 section 22.2. This is, to our knowledge, the first time that an industrial-strength regex language has been faithfully mechanized in an interactive theorem prover. We highlight interesting challenges that arose in the process (including issues of encoding, corner cases, and executability), and we document th…

#TIL Today I learnt that adding `?` after `*` transforms a #regex expression from being "greedy" into "lazy" (important for performance, safe validators, and protection against DoS attacks).
I don't know how I missed this bit of knowledge for so long. :blobfoxbox:

@… Regex sind der Turing-Test an dem die KI scheitert!

Finally remembered to use the new /r flag in a #Perl regex substitution to return the changed value while map'ing over a list: `say join(';', map { s/;/,/gr } @values);`

Nothing weirder than going down the rabbit hole of a random law directory that has tons of self promotion (seriously? Sketchlab as a promotional site?), no external citations or articles, and an "About Us" page hosted on `http://` that has tons of regex errors.
Yet happy to publish a hit piece on a local judge candidate.
If I was a journalist, this would be absolute catnip.

#Python #regex package (not to be confused with the builtin `re` module) relies on CPython implementation details and does not correctly support #PyPy (and the author says they might actually block building on it). However, the #ReAssert package requiring it seems to work just fine with plain `re`.
Today #Gentoo is switching from imperfectly patching regex and ignoring corner cases where it is known to be broken, to patching re-assert instead. I wish I could submit this trivial patch upstream but — as I've complained before — I've been banned and the author is unable to figure out why but that doesn't stop them from feeling righteous about it. Perhaps it was just a proactive ban for downstream packagers.
