scmpuff 💨

Makes working with git from the command line quicker by substituting numeric shortcuts for files.

Build Status Go Report Card Chat on Gitter

scmpuff is a minimalistic reinterpretation of the core functionality of SCM Breeze, without many of the extras.

It is focused on simplicity, speed, robustness, and cross-platform support. The majority of the functionality is contained within a compiled binary, and the shell integration is under 100 lines of shell script.

scmpuff currently functions in bash and zsh in any *nix-like operating system. It's written with cross-platform support in mind, so hopefully we'll have it functioning on Windows soon as well.

scmpuff is fully compatible with the most-excellent Hub.


Download the binary for your platform, and copy it to /usr/local/bin or somewhere else in your default $PATH.

Alternately, if you use homebrew, you can just: brew install scmpuff. 🍺


Currently scmpuff supports bash and zsh for all functionality.

To initialize shell functions, add the following to your ~/.bash_profile or ~/.zshrc file:

eval "$(scmpuff init -s)"

This will define the scmpuff shell functions as well as some handy shortcuts.


Once things are loaded, the most important function you will want to know about is scmpuff_status, which is aliased to gs for short.

This is a replacement for git status that is pretty and shows you numbers next to each filename, for example:

$ gs
# On branch: master  |  +1  |  [*] => $e*
➤ Changes not staged for commit
#       modified:  [1] main.go
➤ Untracked files
#      untracked:  [2] HELLO.txt
#      untracked:  [3] features/shell_aliases.feature
#      untracked:  [4]

You can now use these numbers in place of filenames when calling normal git commands, e.g. git add 2 3 or git checkout 1.

You can also use numeric ranges, e.g. git reset 2-4. Ranges can even be mixed with normal numeric operands.

Behind the scenes, scmpuff is assigning filenames to sequential environment variables, e.g. $e1, $e2, so you can refer to those with other commands too if needed.

By default, scmpuff will also define a few handy shortcuts to save your fingers, e.g. ga, gd, gco. Check your aliases to see what they are.


How do you pronounce it?

💁 I like to say "scum puff." But I'm weird.

How does it compare with SCM Breeze?

The short version: it does less, but is faster and should be significantly more stable and reliable, especially across different platforms.

The long, detailed version:

Can I disable or change the default git shortcut aliases?

You can disable them via passing --aliases=false to the scmpuff init call in your shell initialization. Then, if you wish to remap them, simple modify your default aliases wherever you normally do, but add aliases mapped to the scmpuff shell functions, e.g. alias gs='scmpuff_status'.


While the build process itself does not require it, development uses Ruby for integration testing because of the excellent Cucumber/Aruba package for testing CLI tools.

Thus, to bootstrap, you will need to have Ruby and bundler installed on your system. Do bundle install to get the dev environment going.

Since we already have Ruby then for tests, we use a Rakefile instead of Makefile since it offers some niceties. Do rake -T to see available tasks.
