Read files from remote repository without cloning #940

Closed abitrolly closed 2 years ago

abitrolly commented 2 years ago

Is it possible to list remote repository files without cloning the whole repo?

I am trying to add support to checking license of remote GitLab repos to https://github.com/licensee/licensee And I can't see how to replace Rugged::Repository.new(path) with something that looks up remote files.

https://github.com/licensee/licensee/blob/16b2bf8e2fab709bec87d3ea84650e6b8c4410d0/lib/licensee/projects/git_project.rb#L33

I found this StackOverflow question https://stackoverflow.com/questions/1178389/browse-and-display-files-in-a-git-repo-without-cloning Maybe it is possible to emulate this technique https://stackoverflow.com/a/65464092 without creating files on disk?

Git works on local data. The one exception is fetching data from a remote or pushing data to a remote. If you want to access a Git repository remotely then you'll need to consult your hoster's API reference.

That's fine with me. Fetch list of files and then some contents. Just don't save anything to disk.

That's not how Git works. A fetching data means the equivalent of git fetch. There is no network-based arbitrary data access like what you are describing. For that you'd need the API of whoever is hosting the repositories.
