Issue description

The elm-test package in nodePackages

Steps to reproduce

Via nixpkgs:

$ nix run nixpkgs.elmPackages.elm nixpkgs.nodePackages.elm-test
$ elm-test init
$ elm-test
Success! Compiled 54 modules.                                       
Successfully generated /dev/null
Unhandled exception while running the tests: { Error: spawn /nix/store/rll733jmgykq2sxrjbjgsm8hy6wzpsv8-node-elm-test-0.18.12/lib/node_modules/elm-test/bin/elm-interface-to-json ENOENT

  path: '/nix/store/rll733jmgykq2sxrjbjgsm8hy6wzpsv8-node-elm-test-0.18.12/lib/node_modules/elm-test/bin/elm-interface-to-json',
  spawnargs: [ '--path', '/home/example/empty/tests' ] }

Similar results follow from npm install.

Technical details

The elm-interface-to-json binary installed via npm does not work with NixOS.
After installing via npm install, similar issues arise. The issue was fixed for me by deleting the elm-interface-to-json binary in node_modules/elm-test/bin, and instead linking the copy from the nix store (from elmPackages).

Please run nix-shell -p nix-info --run "nix-info -m" and paste the
results.

Proposed fix

Move elm-test into elmPackages, build it against existing elm-interface-to-json.

https://github.com/mdevlamynck/nixpkgs/tree/elm-test
This branch contains a package for elmi-to-json and a package for elm-test (for elm 0.19.0). These were generated with cabal2nix and node2nix.

Remaining problems:

• elmi-to-json:
  • the dependency rainbow-0.30.0.2 fails to build
• elm-test:
  • the dependency fsevents 1.1.2 fails to build (install script trying to request the url http://www.example.com/glob)
  • the path to the binary elmi-to-json needs to be patched in lib/runner.js.

Try using https://github.com/adisbladis/pnpm2nix for nodejs

[stoeffel]

happy to get rid of rainbow-0.30.0.2. Would totally appreciate a PR ❤️

[mdevlamynck]

I can try to make a PR but I don't know much about haskell or its ecosystem, what would you replace rainbow with?

[stoeffel]

@mdevlamynck I would just remove it completely. It's not really necessary. I might get to it next week, but happy to help you if you have questions. I'm @stoeffel on http://elmlang.slack.com.

[mdevlamynck]

elmi-to-json now builds!

@domenkozar Thanks for your suggestion! I managed to get node-elm-runner building with pnpm2nix. Do you have an example using it within nixpkgs? (nixos noob here).

The issue of patching the path to elmi-to-json remains though. Also I think I might need to also patch the path to elm in node-elm-compiler. Anyway, we're progressing!

[dmvianna]

Any update on this? As it stands, a fairly basic Elm library (its test runner) cannot be used in Nixos. I wasn't able to make it work on OSX either, but it seems that the problem is being pushed down to OSes to fix it. I wonder if anyone have made it run anywhere?

@svanderburg do you have an idea why binwrap-install is missing, given that elmi-to-json depends on binwrap pacakges and tries to execute binary from it?

[turboMaCk]

This is what I do to fix it for now https://github.com/turboMaCk/nix-elm-tools/blob/master/patch-bin-wrap.nix

basically, I mock binwrap with noop script and put elmi-to-json to the expected location in derivation itself.

you can use my thing https://github.com/turboMaCk/nix-elm-tools just note that at this point elmi-to-json itself is downloaded as a binary (darwin or linux).

[domenkozar]

This has been fixed by #63477

[turboMaCk]

just a note that elm-test was moved so it's located in elmPackages.elm-test
