SCM Breeze is a set of shell scripts (for
zsh) that enhance your interaction with tools
such as git. It integrates with your shell to give you numbered file shortcuts,
a repository index with tab completion, and a community driven collection of useful SCM functions.
Disclaimer: git is currently the only supported SCM. I’ve kept the project’s name open because it won’t be difficult to port it for other SCMs.
SCM Breeze makes it really easy to work with changed files, and groups of changed files. Whenever you view your SCM status, each modified path is stored in a numbered environment variable. You can configure the variable prefix, which is ‘e’ by default.
These numbers (or ranges of numbers) can be used with any SCM or system command.
For example, if
ga was your alias for
git add, instead of typing something like:
$ ga assets/git_breeze/config* assets/git_breeze/install.sh
You can type this instead:
$ ga $e2 $e3 $e11
But SCM Breeze aliases
ga to the
which is smart enough to expand integers and ranges, so all you need to type is:
$ ga 2 3 11
And if you want to add all unstaged changes (files 1 to 10):
$ ga 1-10
ga will also remove deleted files, unlike the standard
git add command.
This behaviour can be turned off if you don’t like it.)
You can also diff, reset or checkout a file by typing:
$ gd 3 $ grs 4 $ gco 5
You can use these shortcuts with system commands by passing your command through
(default alias is ‘ge’):
$ echo $e4 # => assets/git_breeze/git_breeze.sh $ ge echo 4 # => assets/git_breeze/git_breeze.sh $ ge echo 1-3 # expands to echo $e1 $e2 $e3 # => _shared.sh assets/git_breeze/config.example.sh assets/git_breeze/config.sh
My most common git commands are
git add and
git commit, so I wanted these
to be as streamlined as possible. One way of speeding up commonly used commands is by binding them to
Keyboard shortcuts are turned off by default, but here are the default key bindings if you enable them:
git_status_shortcuts- show git status with file shortcuts
git_add_and_commit- add given files (if any), then commit staged changes
git_commit_all- commit everything
The commit shortcuts use the
git_commit_prompt function, which gives a simple prompt like this:
And if you really want to speed up your workflow, you can type this:
$ 2 3 <CTRL+x c>
This sends the
HOME key, followed by
The second feature is a repository index for all of your projects and submodules. This gives you super-fast switching between your project directories, with tab completion, and it can even tab-complete down to project subdirectories. This means that you can keep your projects organized in subfolders, but switch between them as easily as if they were all in one folder.
It’s similar to autojump, but it doesn’t need to ‘learn’ anything, and it can do SCM-specific stuff like:
The default alias for
git_index is ’s’, which could stand for ‘source’ or ‘switch’ :)
You will first need to configure your repository directory, and then build the index:
$ s --rebuild # => == Scanning /home/ndbroadbent/src for git repos & submodules... # => ===== Indexed 64 repos in /home/ndbroadbent/src/.git_index
Then you’ll be able to switch between your projects, or show the list of indexed repos:
To switch to a project directory, you don’t need to type the full project name. For example,
to switch to the
errbit project, you could type any of the following:
$ s errbit $ s err $ s rbit
Or if you wanted to go straight to a subdirectory within
$ s err<TAB> $ s errbit/<TAB> # => app/ autotest/ config/ db/ ... $ s errbit/conf<TAB> $ s errbit/config/ # => cd ~/src/rails/errbit/config

It would be cool to make this project into an oh-my-zsh for SCMs.
git clone git://github.com/ndbroadbent/scm_breeze.git ~/.scm_breeze ~/.scm_breeze/install.sh source ~/.bashrc # or source ~/.zshrc
(The install script simply appends the following line to your
[ -s "$HOME/.scm_breeze/scm_breeze.sh" ] && . "$HOME/.scm_breeze/scm_breeze.sh"
SCM Breeze is configured via automatically installed
To change git configuration, edit

I know we grow attached to the aliases we use every day, so I’ve made them completely customizable.
Just change any aliases in
~/.git.scmbrc. You can also change or remove any keyboard shortcuts.
Each feature is modular, so you are free to ignore the parts you don’t want to use.
Just comment out the relevant line in
update_scm_breeze. This will update SCM Breeze from Github,
and will create or patch your
~/.*.scmbrc files if any new settings are added.
SCM Breeze lives on Github at https://github.com/ndbroadbent/scm_breeze
Please feel free to fork and send pull requests, especially if you would like to build these features for Mercurial, SVN, etc.
