> Now augment that GNU list with all relevant free software programming language implementations: > https://directory.fsf.org/wiki/Category/Programming-language
That category in the wiki isn't supposed to be for implementations of languages, it's supposed to be for sorting everything by what language it was implemented in. For instance, the first result on that page, 0AD, is implemented in C++ and Javascript, so it appears when you filter by those languages. The page you linked filters by all languages, so it has everything that has a language listed for it in the directory. -Alan Beadle
