Feature request: download only if hash doesn't match about eget HOT 6 CLOSED

This is something that would be very useful for me also. Just comparing the last modification to the local file to created_at would be very useful. I'd be happy to implement this myself if you'd like.

I don't think there is any way to know the hash of the file to be downloaded without downloading it. Is there any way around that problem?

from eget.

I was under the impression that the JSON data for the latest version (https://api.github.com/repos/zyedidia/eget/releases/latest for instance) includes the hash but apparently it doesn't.

Maybe the created_at or updated_at values could be used ("if there's already a local file with the same name and the file's modification timestamp is younger than the one I would download, don't download the file from GitHub.")

That's a good suggestion, I've implemented it in the form of the upgrade-only flag.

Could you please reopen this issue? The --upgrade-only flag doesn't seem to work - the same same file is downloaded again and again:

@thorstenkampe --download-only is not expected to be specified in conjunction with --upgrade-only.

--download-only will only download the tarball, and not extract it, so when you run it again with --upgrade-only it will check for existence of eget (which doesn't exist because it was never extracted) and will download the tarball again.
