How to write zsh alias for pushing new branch from current local branch?

Right now when i commit and want to push and create remote branch I did:

app_folder (some_branch)> git push -u origin some_branch:some_branch

Is there a way to write zsh alias ex: gpu which get name of current branch and do that without my help?

Solution

Here's a very basic script. Some additional features (and error checking!) are probably needed, but it works:

#!/bin/zsh
function branch() {
    ref=$(git symbolic-ref HEAD)
    echo "${ref#refs/heads/}"
}
# TODO: Let the user set the remote to push to? 
git push -u origin ${branch}:${branch}

The branch() function is taken from Oh-My-ZSH git_prompt_info() - it's used to put the current git branch into the PROMPT.

This would probably work rather well as a zsh function, rather than an alias.
