No SWH evidence indexed yet for this language. (Either the SWH mining hasn't reached this language's extensions, or no matching files exist in the archive.)

Contribute — propose a file extension

Tell us where to find evidence about Kojo (mapped to pl/kojo-learning-environment). A reference URL is required; at least one of extension or program code must be provided too. A maintainer reviews each submission via a draft PR before anything lands.
Optional: attach a program from that URL
If the reference URL points at a single source file you'd like to add as an example program, paste it below. The workflow will write it under languages/Kojo/programs/<sha>/. Keep under ~200 lines.
