Description of issue

The current formula for gmime installs the two year old version 3.2.7 from gnome.org.

As confirmed by the author of gmime in jstedfast/gmime#138 new releases will not be appearing on gnome.org any more. It seems, that the gmime formula should be updated to use the latest release from the gmime GitHub repo instead.

With the below, updated formula file, I could successfully install (brew install --cc clang -s gmime), and use gmime 3.2.13 on macOS 11.7.1. The bottles will also need upadting, of course, as I was building from source. The "flat namespace patch" was not needed on my system (brew audit gmime was happy and produced no output).

[SMillerDev]

Is there any documentation anywhere that those two projects are actually the same? Normally we ask that the original upstream refers to the new location in some official capacity, but judging by the issue you linked that will never happen.

[c-alpha]

Unfortunately I couldn't find any official information on the Gnome side.

OTOH, I would read the author's comment on the issue I linked, as implying that the GitHub repo is the successor to the Gnome one?

[c-alpha]

So how do we proceed now? An issue against the gmime formula?

[SMillerDev]

No, a pull request to make the changes

[c-alpha]

A pull request... by whom?

[SMillerDev]

Whoever wants to have this change.
