Cloning Specific Version from Crates.io

[iwillspeak]

I'm trying to clone a specific version of a crate from Crates.io using this command. The crate version is 64.0.0. If i run cargo clone --vers 64.0.0 onig_sys I get version 64.0.1 rather than 64.0.0. I can clone 63.0.0 successfully. It looks like the --vers string is being treated as ^64.0.0 not =64.0.0.

I tried using =64.0.0 and <=64.0.0 but got the error error: cannot parse '=64.0.0' as a semver.

Any update on this?

It is even worse:

cargo clone tokei --vers 6.1.3 clones 6.1.3
cargo clone tokei --vers 6.1.2 clones 6.1.3 as well
cargo clone tokei --vers =6.1.3 throws an error with cannot parse '=6.1.3' as a semver.

@JanLikar is it possible to clone a specific version? May be I am missing something?

[JanLikar]

The version argument gets passed to cargo and is not altered by cargo-clone in any way. I guess this is the default behaviour... The only thing I can say at this time is, I will have to check what builtin commands do with the version specification and mimic that, because mirroring Cargo builtins is one of the goals of this crate.

rust-lang/cargo#4229 may include the answer to this issue.

It looks as if wrapping the passed down arguments explicitly in quotation marks will make sure it gets parsed correctly, and the ranges will be respected.

Edit: I was finally able to test this and also does not work. Interesting, will keep digging.

Just use whatever the equivalent of --precise is

this is still broken

I'll see what I can do, I have some time for this now.
