Great improvements for the packager , thanks!

In other way i'll try to try it on OSX , but i have errors (i'm novice with nix), i do this steps:

1. Clone nixpkg repo
2. checkout fern/icestudio
3. Go to icestudio dir
4. Excecute nix-build package.nix

but i receive the error error: cannot evaluate a function that has an argument without a value ('fetchurl')
Nix attempted to evaluate a function as a top level expression; in
this case it must have its arguments supplied either by default
values, or passed explicitly with '--arg' or '--argstr'. See
https://nixos.org/manual/nix/stable/language/constructs.html#functions.

I'm asking you if there is a beginners guide or some documentation that you recomended.

Thanks for wanting to try it!

Clone nixpkg repo
checkout fern/icestudio
Go to icestudio dir
Excecute nix-build package.nix

The last step is not what you need to run. From the root of the nixpkgs repo, and after checking out the fern/icestudio branch, run nix-build -A icestudio. This means "build the attribute icestudio" which, sure, is a package for us, but for the package manager is an attribute.

After a hopefully successful build, a result directory will appear. You can then run ./result/bin/icestudio.

For documentation i'd check out nix.dev, like https://nix.dev/tutorials/packaging-existing-software.html#your-first-package.

Regarding this PR, it actually contains an error due to my misunderstanding of the clean:collection task. Although it says that it removes the previously downloaded collection, it removes both the downloaded collection and the unzipped collection, so the build will not be correct. May I ask to reopen this PR? I'd like to add a fix. Thanks!

The Merge is reverted!

And dont worry was my fault, i'm not remember well what "clean collections" do and i don't check in deep.

Hi! i'm trying to build in osx, but several errors appears, one of them and i think the first to start (others, i think are promoted by this one) in nixpkgs osx is not supported by nwjs pkg:

  error: Package ‘nwjs-0.88.0’ in /Users/carl/work/nixpkgs/pkgs/development/tools/nwjs/default.nix:141 is not available on the requested hostPlatform:
         hostPlatform.config = "aarch64-apple-darwin"
         package.meta.platforms = [
           "i686-linux"
           "x86_64-linux"
         ]

i'll try to add support to this!

Thank you so much for trying it! We'll definitely use your help I think 😄!

Hello @kiike! i have managed to package in nix nwjs for osx!!! Tomorrow I'll try to pack icestudio! I'm learning a lot through the process with nwjs. I feel more comfortable with nix at every step :)

Hi @kiike ! 'm forking nixpkgs and launch the PR for nwjs support.

Then i'm trying to checkout in my fork to fern/icestudio but i don't find it, you move it? in wich branch is icestudio now? thanks!!

Hey @cavearr! Nice! I'm excited you are taking these steps 👍! The branch is still active, but it lives in @jackleightcap's fork. So just add his remote. https://github.com/jleightcap/nixpkgs/ branch: fern/icestudio.

Ou!! sorry!! i'm fork from your PR and i not show it sorry! i have a PR for nwjs to the nixpkgs yesterday , in the afternoon or tomorror i'll do it to your fork (nwjs and icestudio).

Thanks again for your patience!
