Shouldn't this be 0.1.0? See https://github.com/andreasKroepelin/polylux/blob/main/pdfpc-extractor/Cargo.toml#L5

[diogotcorreia]

I wasn't sure what to put as the version, since the author doesn't seem to be properly releasing tags for this "sub package". I'm afraid that the code might change in the future without the version changing.

I settled on 0.3.1 because that's what the AUR package is using: https://aur.archlinux.org/packages/polylux2pdfpc (and this tool was only introduced in version 0.3.0 of the parent package: https://polylux.dev/book/changelog.html)

If you think 0.1.0 is preferable (or unstable-2023-08-25, the date of the last commit on that folder), I have no objections to changing it to that.

Thoughts?

Thoughts?

Open an upstream issue.

Do you think you could make it work on aarch64-darwin as well ?

[diogotcorreia]

@drupol Hm... I'm not sure if I know how to do that. What do I need to add to the derivation?
And is it possible to test if it works from a linux (x86_64) machine?

[drupol]

I have the feeling that it's an unrelated issue. Going to merge it as it is.

Thanks for making the PR, it is now merged. I believe we won't have to use it much since there's a PR in Polylux to extract those data without using any external tool. See: andreasKroepelin/polylux#123
