Streamline your SCM workflow.
SCM Breeze is a set of shell scripts (for
zsh) that enhance your interaction with git. It integrates with your shell to give you numbered file shortcuts,
a repository index with tab completion, and many other useful features.

- File Shortcuts
- Keyboard bindings
- Repository Index
- Linking External Project Design Directories
- Contributing tools / scripts

Adding a range of files, and pressing
Ctrl+X, C to commit:
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.
Git Status Shortcuts:
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
SCM Breeze adds a number of aliases to your shell. Use
list_aliases to view all the aliases and their corresponding commands.
You can filter aliases by adding a search string:
list_aliases git log
There's also a
git_aliases command, which just shows aliases for
git commands. You can also pass in additional filters, e.g.
Some of 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
Here are the default key bindings:
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:
(When using bash, this commit prompt gives you access to your bash history via the arrow keys.)
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:
- Running a command for all of your repos (useful if you ever need to update a lot of remote URLs)
- Update all of your repositories via a cron task
The default alias for
git_index is 'c', which might stand for 'code'
You will first need to configure your repository directory, and then build the index:
$ c --rebuild # => == Scanning /home/ndbroadbent/code for git repos & submodules... # => ===== Indexed 64 repos in /home/ndbroadbent/code/.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
capistrano project, you could type any of the following:
$ c capistrano $ c cap $ c istra
Or if you wanted to go straight to a subdirectory within
$ c cap<TAB> $ c capistrano/<TAB> # => bin/ lib/ test/ $ c capistrano/l<TAB> $ c capistrano/lib/ # => cd ~/code/gems/capistrano/lib
Or if you want to go to a subdirectory within the
~/code directory, prefix the first argument with a
~ $ c /gems ~/code/gems $
Linking External Project Design Directories
When you're creating logos or icons for a project that uses
have you ever wondered where you should store those
Do you commit all of your raw design files, or does it put you off that any changes to those files
will bloat your repository?
Here were my goals when I set out to find a solution:
- I wanted a design directory for each of my projects
- I didn't want the design directory to be checked in to the git repository
- The design directory needed to be synchronized across all of my machines
The simplest way for me to synchronize files was via my Dropbox account.
However, if you work with a larger team, you could set up a shared design directory on one
of your servers and synchronize it with
1) Create and configure a root design directory
I created my root design directory at
After you've created your root design directory, edit
~/.scmbrc and set
to the directory you just created.
You can also configure the design directory that's created in each of your projects
design_assets), as well as the subdirectories you would like to use.
The default base subdirectories are: Images, Backgrounds, Logos, Icons, Mockups, and Screenshots.
After you have changed these settings, remember to run
source ~/.bashrc or
2) Initialize design directories for your projects
To set up the design directories and symlinks, go to a project's directory and run:
If your root directory is
~/Dropbox/Design, directories will be created at
It will then symlink the project from your root design directory into your project's design directory, so you end up with:
It also adds this directory to
.git/info/exclude so that git ignores it.
If you use the git repository index, you can run the following batch command to set up these directories for all of your git repos at once:
git_index --batch-cmd design init
If you want to remove any empty design directories, run:
And if you want to remove all of a project's design directories, even if they contain files:
3) Link existing design directories into your projects
If you've set up your design directories on one machine, you'll want them to be synchronized across all of your other development machines.
Just run the following command on your other machines after you've configured the root design directory:
This uses your git index to figure out where to create the symlinks. If you don't use the git index, the same outcome could be achieved by running 'design init' for each of the projects.
Contributing tools / scripts
If you have any awesome SCM scripts lurking in your
please feel free to send me a pull request.
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 creates required default configs and adds the following line to your
[ -s "$HOME/.scm_breeze/scm_breeze.sh" ] && source "$HOME/.scm_breeze/scm_breeze.sh"
Note: SCM Breeze performs much faster if you have ruby installed.
update_scm_breeze to fetch the latest code. This will update SCM Breeze from Github,
and will create or patch your
~/.*.scmbrc config files if any new settings are added.
The uninstall script removes the following line from your
[ -s "$HOME/.scm_breeze/scm_breeze.sh" ] && source "$HOME/.scm_breeze/scm_breeze.sh"
SCM Breeze is configured via automatically installed
To change git configuration, edit
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
Note: After changing any settings, you will need to run
source ~/.bashrc (or
I know we grow attached to the aliases we use every day, so I've made the alias system completely customizable. You have two options when it comes to aliases:
1) Configure and use the provided SCM Breeze aliases
Just tweak the aliases in
~/.git.scmbrc. You can also change or remove any keyboard shortcuts.
These aliases also come with tab completion. For example, you can type
gco <tab> to tab complete your list of branches.
2) Use your own aliases
git.scmbrc config file, just set the
git_setup_aliases option to
Your existing git aliases will then be used, and you will still be able to use the numeric shortcuts feature.
SCM Breeze creates a function to wrap the 'git' command, which expands numeric arguments, and uses
hub if available.
A few aliases will still be defined for the central SCM Breeze features, such as
gs for the extended
ga for the
git add function.
If you already have an alias like
alias gco="git checkout",
you can now type
gco 1 to checkout the first file in the output of SCM Breeze's
Notes about Tab Completion for Aliases
If you use your own aliases, SCM Breeze will not set up bash tab completion for your aliases. You will need to set that up yourself.
You just need to set the option:
setopt no_complete_aliases (oh-my-zsh sets this by default).
Zsh will then expand aliases like
git branch, and use the completion for that.
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.
