I might get around to implementing that later. For now, please just use a git client like Magit on Emacs or Working Copy on iOS, or just plain git in a shell.
I’m not too fond of them myself, but many of them can import off-site repos just fine.
For example, here are instructions for how to do that on GitHub.
Here is how to do it on sourcehut.
Either git send-email or git request-pull is fine.
Here’s a tutorial for git send-email.
Here’s pyonji, an app by emersion that makes sending a feature branch easier.
If it’s security stuff, email me directly.
My GPG key is here.
For non–security-related patches and issues, there’s a public inbox.
I hear they can import or export to git just fine.
If you’re using CVS or some other non–git-compatible VCS, you’re just gonna have to have a .git in parallell with what ever you’re doing in that other thing and commit there too.
I got burned pretty badly by darcs and its theory of patches. Git’s model as a content-addressable file system suits me just fine.♥︎
