Hi I'm also interested in using the erlang_nox version.
I'm currently using elixir = pkgs.beam.packages.erlangR21.elixir_1_8;.
But with your version I think I'm not able to use erlangRxx_nox - only the default version (currently erlangR20).

So I think the solution would be to just use elixir = (pkgs.beam.packagesWith pkgs.beam.interpreters.erlangR21_nox).elixir_1_8; in my case.
Which would make this PR obsolete?

But I'm far away of an Nix expert, so just my thoughts.

Yeah I use this too, but adding erlang_nox will make hydra build beam packages with erlang_nox and produce pre-build packages right ? (I'm not sure about this 🤔 )

I think your deliberation is right.
But it only then would be faire to add the nox version of all current Erlang versions as package,
which then is going quite far in my opinion, as the nox version is quite specialized and not that widely used.

So I think the better solution for us would be to use Cachix instead?

But I'm sure it's a pain to build yourself up front - as it's taking quite some minutes.

Thank you for your contributions.

This has been automatically marked as stale because it has had no activity for 180 days.

If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity.

Here are suggestions that might help resolve this more quickly:

1. Search for maintainers and people that previously touched the related code and @ mention them in a comment.
2. Ask on the NixOS Discourse.
3. Ask on the #nixos channel on irc.freenode.net.

In that case this PR should also make the other variants (e.g. _javac) and these variants for all available versions of Erlang/OTP available.

I can add them, but I don't know much about these version, maybe if another user need them it will make a pull request ? the nox version is very handy for a server for example when you don't want that your erlang application pull all theses dependencies

There is not much to know about. Just like the _nox variant they simply disable certain features. So its a mere copy and paste for all of these. I think if anything it really should be done for all or none.

@DeltaEvo Are you planing to adapt the PR?

I don't have the time now, so I am not planing to adapt it :(

I think this is now in the main repo. Perhaps we can close this now?
Feel free to update if I'm wrong.

Since this is already on master, I am going to close this for now, feel free to re-open if I'm wrong
