In France, not only our law are versioned. It's formally proved too!

https://catala-lang.org/

*Edit*: Woah ! The French crew is here. We are at least 5 quoting a variation of <https://www.legifrance.gouv.fr/> for versioning.

I find it ironic to have it named "catalan(g)" on a post about spanish law.

Even better. The Catalan word for Catalan is català. So catala-lang.org fits that too.
