darklang / tablecloth

See #182. Note the problem here seems to be that the standard OCaml docker container does not support 4.11 yet: https://github.com/ocaml/infrastructure/wiki/Containers

OCaml docker now supports 4.11 and 4.12. What changes need to be made to make this project work with OCaml 4.11?

I believe you just need to add it to the list here, and then see what comes up.

Hmmm... so these are the changes I made:

But tablecloth still won't install on an Ocaml 4.11 switch:

❯ opam install .
[NOTE] Ignoring uncommitted changes in /Users/ethanbrooks/tablecloth (`--working-dir' not active).
[tablecloth-native.0.0.7] no changes from git+file:///Users/ethanbrooks/tablecloth#master
The following dependencies couldn't be met:
  - tablecloth-native → ocaml < 4.11
      base of this switch (use `--unlock-base' to force)

No solution found, exiting

I am a little new to opam so thank you for walking me through this.

Hmm, I actually don't know what's going on here. It feels like something stale is happening maybe?

Are you thinking there is some kind of cache that we need to delete?

Yeah. I can't imagine any other reason it would think it needed < 4.11 once it's been removed from the opam file.

Do you think this is an issue for opam?

Hmmm, I'd try again with a clean switch first.

Looks like that was the issue. Opam had retained the previous attempt to install tablecloth, before removing the upper bound.

Now supported

Add support for OCaml 4.11
