The problem

Actually, we use the learn-ocaml-corpus made by Mr.Alain in learn-ocaml-essok. Unfortunately, theses exercises do not work with Learn-OCaml v0.12 (I think this is due to conception of new exercises using the last version of Learn-OCaml).

Wanted solution

As a solution, we will need a new release, that way we can update our learn-ocaml-dockerfile Dockerfile to make exercises work properly.

Considered alternatives

As a workaround, I have created a custom docker repository (using learn-ocaml:master docker image) to make exercises working.

Thanks for the report! I was thinking that learn-ocaml-corpus was still compatible with ocamlsf/learn-ocaml:0.12 …

So I tried to reproduce the issue and got this error indeed:

$ cd learn-ocaml-corpus
$ docker run --rm -it -v "$PWD:/repository" ocamlsf/learn-ocaml:0.12
Learnocaml v.0.12 running.
Updating app at ./www   
Cannot process exercises: Unix.Unix_error(Unix.EEXIST, "mkdir", "./www/static")  

− side question: do you believe you got the same error, or another one?

So, indeed we should make a release to overcome this
(in the meantime I guess you can do FROM ocamlsf/learn-ocaml:master in your Dockerfile, but you're right that having a new release tag would be much more stable… (BTW, I'm unsure why it was necessary for you to create another custom Docker Hub repo asere/learn-ocaml-essok-dockerfile:master because you might have used ocamlsf/learnocaml-essok-dockerfile:master))

Regarding the release, @yurug and I need to discuss a number of things for preparing the release, and we plan to video-meet soon, then when we've some news, we'll be able to comment in this issue :)

Yes, this is exactly the error I have on some exercises.

Yes, I have thought about that. I highly prefer to avoid making PR in learn-ocaml-dockerfile for workarounds.

OK @asere! thanks for your feedback.

So @yurug and I were able to discuss today, so if everything goes smoothly… we could release learn-ocaml 0.13 by the end of this week 😅

(FYI we opened a "meta-issue" to recap the remaining steps to address: #418)
