Create flake.nix for CLI

[BD103]

This is adopted from #532, huge thank you to @CupOfTeaJay!

cargoBuildFlags = [ "--all" ];

You need --all so that bevy_lint also gets built.

postInstall = ''
  for bin in $out/bin/bevy{,_lint}; do
    wrapProgram $bin --set BEVY_LINT_SYSROOT ${toolchain}
  done
'';

BEVY_LINT_SYSROOT wrapper is necessary here, so that it can function on a non-rustup system.

Any blockers on this PR? The fixes above are very straightforward, so I'm not sure why it's getting stalled for months.

@foob2483-oss @musjj Could you test again if i applied the suggestions correctly? If so i will merge thanks! Never mind CI is failing now ^^ im more than happy if someone adopts this!

You just need to run nix flake update to update the lockfile. Its current database of nightly versions is outdated so it doesn't include 2026-03-05.

I've tested it and it works! You can test it yourself on your local project like this:

$ nix run github:TheBevyFlock/bevy_cli/cli-flake.nix -- lint
