Solution

  • how to pull a PR from a different repo/fork?

    If you have the ID of the PR, as mentioned in "Checking out pull requests locally", the fetch URL would be 

    git fetch origin pull/ID/head:BRANCHNAME

    Applied to a porfile, with fetch.type set to git, you can try as a branch name

    git.branch          origin/pull/ID/head

    As neverpanic adds in the comments:

    Note that while you can set fetch.type git and git.branch origin/master, this is not supported by MacPorts.
    It's fine for development, but when trying to get a Portfile included in MacPorts, we expect that a certain version of the Portfile will always produce the same result, regardless of when you install it.

    For git submodules, add post-fetch { system -W ${worksrcpath} "${git.cmd} submodule update --init" } together with fetch.type git.
