Feature Request: Support compressed (non-archived) tools

[rafikk]

I want to use multitool to download a binary (taplo) that's distributed as a gzip-compressed executable. That doesn't seem to be supported by this rule set as only archives are able to be decompressed.

Do you think this is something that could be supported? I know it's nontrivial since the module extension uses rctx.download and rctx.download_and_extract which doesn't private a primitive for downloading and decompressing a single file.

For reference, aspect_rules_lint which uses this rule set to download several tools (yamlfmt, terraform, etc.), uses a raw http_file to download taplo along with a genrule to unwrap it. It would be great if we could natively support this in the multitool extension instead.

The readme describes how to set kind to “archive” and tgz/tar.gz is supported.

Sorry, I see this is only compressed, I misread initially. There’s some challenges supporting something here since we’d need a portable gzip rule to depend on, ideally it’s something Bazel’s download would support handling for us

Looks like support for this will land soon in Bazel: bazelbuild/bazel#27413.
