Indexed languages are cross-referenced from languages/**/meta.json (LLM-curated) and seven upstream sources (PLDB, Linguist, Pygments, Wikipedia, Esolang, Hyperpolyglot, Rosetta Code). Each PL page shows which sources mention it, what extensions it claims, and real archived programs from Software Heritage. The example programs gathered by LLM agents are an experiment and are not verified (some were found altered or invented); the goal is a complete list of programming languages grounded in sources, with programs archived by Software Heritage. See Stats for coverage and Extensions catalog for per-extension claimants & heuristics.
