[bug#35813] [PATCH] Add crate-recursive-import.

[Brian Leung]

Hi Efraim,

An updated patch is attached.

I was and still am confused why my previous patch was yielding duplicates. I'm not getting duplicates right now, even with packages that previously yielded duplicates (I tried this on ripgrep); please test and let me know if there are any issues. Maybe I fixed the issue in the course of rebasing?

And "guix import crate -r asfeusnoetuhesont" should now print "failed to download meta-data for...", though I don't know how to do this more idiomatically without using error or leave (which would end the recursive import earlier than desired). And the double quotes actually appear, which is not ideal. I'd appreciate any advice on how to clean this up.

Best,

Brian

I ran 'guix import crate -r afl' on a machine where I had a bunch of
crates pre-packaged the (very shorted output looked like this:

(define-public rust-xdg
...

(define-public rust-xdg
...

(define-public rust-afl
  (package
    (name "rust-afl")
    (version "0.4.4")
    (source
      (origin
        (method url-fetch)
        (uri (crate-uri "afl" version))
        (file-name
          (string-append name "-" version ".tar.gz"))
        (sha256
          (base32
            "14k6hnwzqn7rrs0hs87vcfqj4334k9wff38d15378frlxpviaard"))))
    (build-system cargo-build-system)
    (arguments
      `(#:cargo-inputs
        (("rust-cc" ,rust-cc)
         ("rust-clap" ,rust-clap)
         ("rust-rustc-version" ,rust-rustc-version)
         ("rust-xdg" ,rust-xdg))
        #:cargo-development-inputs
        (("rust-rustc-version" ,rust-rustc-version)
         ("rust-xdg" ,rust-xdg))))
    (home-page "https://github.com/rust-fuzz/afl.rs")
    (synopsis
      "Fuzzing Rust code with american-fuzzy-lop")
    (description
      "Fuzzing Rust code with american-fuzzy-lop")
    (license #f)))

I know rust-xdg is there twice, but IMO it should only be printed once.

also 'guix import crate -r rusty-fork' gives me #f
'guix import crate rusty-fork' gives me:
guix import: error: failed to download meta-data for package 'rusty-fork'
