Manix Crashes on Cache building

[bayou-brogrammer]

Running manix straight from an install produces the following error:

Building Nixpkgs comments cache...
thread '<unnamed>' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 2, kind: NotFound, message: "No such file or directory" }', src/comments_docsource.rs:178:65
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Havent been able to get around this

I am suffering the same issue!

This seems to be caused by https://github.com/NixOS/nixpkgs/commit/271eb0299503892944986eb381b79ec09ea2f2a4

https://github.com/NixOS/nixpkgs/tree/271eb0299503892944986eb381b79ec09ea2f2a4/pkgs/test/nixpkgs-check-by-name/tests/symlink-invalid/pkgs/by-name/fo/foo contains an invalid symlink

I just had the same issue after nix profile install manix on my machine(which is NOT NixOS). This essentially makes this cli/project useless currently thus would appreciate your attention @mlvzk :

The last commit was 2 years ago. I just think it's dead at this point

[evelant]

It seems the original maintainer of this project is no longer active here or at all on github. Maybe we can point nixpkgs to a working fork if anyone is willing to maintain it?

[waalge]

@evelant I'm happy to try

[bayou-brogrammer]

If anyone is still around, I forked the repo and updated it to a working state.

@lecoqjacob Perhaps you can create a PR on nixpkgs to change nixpkgs to use your working fork?

Yea I already have a PR up to switch maintainers! Should be good in a few days

@lecoqjacob @waalge It's possible to filter all the broken stuff out in find_nix_files https://github.com/nix-community/nixpkgs-lint/blob/master/src/find.rs

Oh this is a good find! I'll need to upstream this in my fork

[IogaMaster]

@ParetoOptimalDev We have now done this. https://github.com/nix-community/manix

Working on updating the nixpkgs version
