Right, the problem is that both constructs `git branch --list --format=<format> <branch>` and `git remote get-url <remote>` works only under git v2 (not exactly sure about the minor version) but they do not work under git 1.7.1 and git 1.8.3, it seems.
Anyway, i figured i was too fuzzy in what kind of url i actually need. I thought about it a bit more and figured that I probably this
function git_branch_remote {
branch_remote="$(git -C "$GIT_ROOT" config --get
branch."$GIT_BRANCH".pushRemote)" if [ -z "$branch_remote" ]; then
branch_remote="$(git -C "$GIT_ROOT" config --get remote.pushDefault)"
fi if [ -z "$branch_remote" ]; then
branch_remote="$(git -C "$GIT_ROOT" config --get
branch."$GIT_BRANCH".remote)"
fi if [ -z "$branch_remote" ]; then
branch_remote="origin"
fi echo "$branch_remote"
}
Because basically, if some wants to go for triangle workflow, then push url remote should be preferred because that's where user has write access. If not, then there is a fallback to branch.<branch>.remote and to origin eventually, which is just nice to have cause it makes a minimal setup for my app easier.
So basically, it is possible that an effective (where git actually pushes when `git push` is invoked) remote for pushing will be different than what that function returns (e.g. when git 1.7.1. is used which doesn't know about branch.<branch>.pushRemote and remote.pushDefault) but it doesn't really matter as long as a user is able to make a local configuration where effective push remote and remote returned by the fuction will align.
Then i also need 'origin' being returned immediatelly after clean clone but that's the case as well.
So when i have this kind of 'abstracted' remote, then i need to take pushUrl on one place and fetch url on another but there should be no problem there.
Sorry, i didn't realize i actually kind of this 'hybrid remote' thing. There still might an easier way to write that function (in a compatible way). Not sure about that.
Anyway, thanks clime
