Cannot generate the with_problematic_crates Cargo.nix sample

[nlewo]

I'm trying to (re)generate the Cargo.nix file from the sample project with_problematic_crates but my crate2nix doesn't generate the same file (libPath attributes are missing for instance)

Here are the commands I executed:

[lewo@tilia:~/repos/crate2nix]$ git log -n1 --oneline

The Cargo.nix file I generated: nlewo@047ae1d#diff-d44232a1e2e6e2b12c8e1ef2226078bc

Did I miss something or is it an real issue?

Hmm, good question.

So, unfortunately, the cargo metadata command generates "opaque package IDs" which include local directory paths (see known issues in README). So these changes are expected.

The rest are not. Especially the libPath = "lib.rs" things should not be added since e2a0cc6, I guess?

In general, some of the changes could be explained by a cargo update but I did not see changes in the Cargo.lock file. I would hope that cargo produces reproducible output for cargo metadata with a given lockfile (except the packe ID problem).

[kolloch]

Any ideas how to follow up on this?

Maybe you can try executing the "./regenerate_cargo_nix.sh"
