Codeberg @Codeberg doesn't currently detect and display Interlisp sources, which it handles as binary files. I submitted a feature request for adding Interlisp support to Forgejo:
https://codeberg.org/forgejo/forgejo/issues/8184
The developers started working on the feature and merged a pull request:
https://codeberg.org/forgejo/forgejo/pulls/8377
Thanks Forgejo and Codeberg!
