Rahul Yadav 340b587e94 sync: Support SYNC_BRANCH to override the smart sync branch
`repo sync -s` always sends the manifest branch to the manifest server
as the `branch` argument of GetApprovedManifest. Some servers map one
manifest branch to several server-side (CI) branches, and the only way
to pick among them was indirectly through the target.

Honor a SYNC_BRANCH environment variable, mirroring SYNC_TARGET: if set
and non-empty, send it instead of the manifest branch. An empty value
is treated as unset. -t/--smart-tag is unaffected.

repo

Repo is a tool built on top of Git. Repo helps manage many Git repositories, does the uploads to revision control systems, and automates parts of the development workflow. Repo is not meant to replace Git, only to make it easier to work with Git. The repo command is an executable Python script that you can put anywhere in your path.

Contact

Please use the repo-discuss mailing list or issue tracker for questions.

You can file a new bug report under the "repo" component.

Please do not e-mail individual developers for support. They do not have the bandwidth for it, and often times questions have already been asked on repo-discuss or bugs posted to the issue tracker. So please search those sites first.

Install

Many distros include repo, so you might be able to install from there.

# Debian/Ubuntu.
$ sudo apt-get install repo

# Gentoo.
$ sudo emerge dev-vcs/repo

You can install it manually as well as it's a single script.

$ mkdir -p ~/.bin
$ PATH="${HOME}/.bin:${PATH}"
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/.bin/repo
$ chmod a+rx ~/.bin/repo

Shell Completion

Repo includes completion scripts for Bash and Zsh.

Bash

To enable completion in Bash, source completion.bash in your ~/.bashrc:

source /path/to/git-repo/completion.bash

Zsh

To enable completion in Zsh, you can either:

  1. Copy or symlink completion.zsh to a file named _repo in a directory in your $fpath:

    mkdir -p ~/.zsh/completion
    # You can copy the file:
    cp /path/to/git-repo/completion.zsh ~/.zsh/completion/_repo
    # Or symlink it:
    ln -s /path/to/git-repo/completion.zsh ~/.zsh/completion/_repo
    

    Then add that directory to your fpath in ~/.zshrc before compinit:

    fpath=(~/.zsh/completion $fpath)
    autoload -Uz compinit
    compinit
    
  2. Or source the file directly and call compdef in your ~/.zshrc:

    source /path/to/git-repo/completion.zsh
    compdef _repo repo
