Ability to filter out matching candidates

[ngirard]

Consider the following scenario:

❯ eget --asset=deb --asset=amd64 sharkdp/fd
2 candidates found for asset chain: please select manually
(1) fd-musl_8.4.0_amd64.deb
(2) fd_8.4.0_amd64.deb
Enter selection number: 

Here, as often in the Rust ecosystem, the binaries come as either (1) statically linked to musl (fd-musl_8.4.0_amd64.deb) or (2) dynamically linked to glibc (fd_8.4.0_amd64.deb). By common practice, when nothing is specified within the asset name, the latter is implied.

Since I encountered problems with programs linked to musl in rare occasions, I wish to prefer programs dynamically linked to glibc, when available.

Hence, I wish there was such -x | --exclude option that would allow me to --exclude=musl and thus lead me to the desired asset.

So, you essentially want an inverse of --asset, right? Where -a is used to find assets containing a string, -x would be used to find assets not containing a string. Interesting!

This is offtopic, but I find it amusing that users can have totally opposite usecases, as I always try to download a static musl binary so I can run it on boxes with very old GLIBC. @ngirard What problems have you seen with musl linked programs?

:-)

What problems have you seen with musl linked programs?

I'm afraid I don't recall but they were blocking problems, either the program didn't start or misbehaved.

It's also generally agreed that musl leads to lower performance, although it's not my priority atm.

[dufferzafar]

I have seen apps with bad musl builds as well - where in the binary just doesn't run, I've always left that as bad compilation. See for eg. this issue

I didn't know about the musl allocator perf issues, but as you said, perf is not as critical as just being able to run the thing.

This is now support with ^ syntax. For example eget --asset=deb --asset=amd64 --asset=^musl sharkdp/fd
