2 years ago I tried this at main...symlinks but couldn't make it work, so I gave up, I even started suspecting there is a problem in the tar lib itself.

ya haha, I saw your PR already,
I wanna try again that's all ahah

but I saw you said you were facing a panic while archiving which I am not,
could you share more details about the problem you faced?

I found out in your PR you did not give the link type which is required by the append_link function.

/// You must set the entry type to either [`EntryType::Link`] or [`EntryType::Symlink`].

pleases correct me if I am wrong.

right now I am facing the unpack does not unarchive the symlink file out from the test case which I tried to add, but it can work well by the compiled binary... ahah...

thanks

right now the tar one should be fixed, I am studying the zip one 🙇🏻

Oh, I'm glad you're taking a look at it! Really do appreciate the help as I couldn't figure out the solution by myself. Sorry if I worded that ambiguously.

could you share more details about the problem you faced?

I don't quite recall, but you're right, maybe I forgot to pass the correct argument.

I am studying the zip one 🙇🏻

I initially thought that Zip didn't support symlinks 🤦 looks like it does, for this PR we also need to see what's done for 7Zip.

Hi, the zip one is fixed, and the 7z does not support symlink compression.
Please help review it while you have time.
thanks.

Looking great! One last thing: please add an entry to CHANGELOG.md so it appears in the release notes. :)

Hi @marcospb19, I added the changelog entries. You might modify those if they do not meet the format.
Thanks.
