Could the ‘extracting’ downloader be built on top of the regular
downloader? More concretely:
(package
(name "some-package-from-hex")
(source
(extract-from-hex
(origin
(method
"http://some-url-pointing-to-a-tarball-wrapped-in-a-tarball")
(sha256 (base32 <hash of the wrapper tarball>)))))
(build-system ...))
Here, 'extract-from-hex' would turn a file-like object into a <extract-
from-hex>, which lowers to some derivation extracting the tarball from
the tarball. (guix upstream) might need to be modified to support
<extract-from-hex>.
Also, is there some fundamental reason that hex.pm wraps tars inside
tars and only provides the wrapped tars, or could hex.pm be convinced
to also serve the underlying tars directly?
A benefit of delegating the actual downloading to url-fetch, is that
(guix scripts perform-download) would be used, so connections could be
cached.
Greetings,
Maxime.
