    To those who have used it: is it handy for situations where you have multiple repos that want to share a little code, but it's not worth the trouble of extracting a library, referencing it, publishing versioned releases, updating dependent repos, etc?

    And instead just "sync" a code folder from one main repo (perhaps containing common domain models) to other repos?

    Basically the Go philosophy that a little bit of copying is better than a lot of dependency?

    Some other interesting tools in the space. Rust is using a tool called Josh to sync commits:

    The blog post from the Rust people:

    Meta used to have an open source tool called fbshipit. But according to its open source repo they no longer use it:

    Any others in this space?

    Nice, I built something similar ~5 years ago using nested git repos and scripts to accomplish a similar purpose of combined private and public repos.

    My shell script definitely wasn't google scale tho!

      Yep, same. I thought it might a wrapper around git subtree but looks like it’s doing quite a lot more!

      For example altering commit author emails during sync
