Introduction

This is a collection of simple command-line scripts, bash aliases, and bash utilities that make using git even easier.

The command-line scripts include:

• feature - make working with feature branches easier
• xgrep - make using git-grep easier

The command-line scripts are written in Ruby 2.x using just the standard libraries and do not require any gems to be installed. For OS X users, these should just work out-of-box.

The bash utilities come directly from the git source contrib and include:

• support for tab completion
• support for repository status in your shell prompt

Installation

Clone the repository

mkdir -p ~/GitHub/rkiel
cd ~/GitHub/rkiel
git clone git@github.com:rkiel/git-utilities.git

To add the scripts to your path, add the following to .bash_profile

export GIT_UTILITIES_BIN="~/GitHub/rkiel/git-utilities/bin"

export PATH=${GIT_UTILITIES_BIN}:$PATH

To enable bash tab completion for git commands, add the following to .bash_profile

source ~/GitHub/rkiel/git-utilities/dotfiles/git-completion.bash

To enable your bash prompt to display repository status, add the following to .bash_profile

source ~/GitHub/rkiel/git-utilities/dotfiles/git-prompt.sh

Here's a sample prompt that includes the current branch (i.e. $(__git_ps1 " %s"))

export PS1='[\[\e[0;35m\]\u@\h\[\e[0m\] \[\e[1;34m\]\W\[\e[0;32m\]$(__git_ps1 " %s")\[\e[0m\]]\$ '

To include the bash aliases and enable tab completion for the feature script, add the following to .bashrc

source ~/GitHub/rkiel/git-utilities/dotfiles/bashrc

Feature utility

Usage

This utility is built around some standard branch names: master, develop, and integration.

Feature branches have specific format: USER-BASE-FEATURE.

• USER is the username as specificied by the USER environment variable
• BASE is the standard branch to base the feature branch on
• FEATURE is the name of the feature

Start

To start a new feature, go to one of the standard branches.

git checkout master

Use the start subcommand with a feature name.

feature start my new feature

For example, a new branch will be created called rkiel-master-my-new-feature

Rebase

Use the rebase subcommand to pull down any changes from the standard branch and then rebase with your feature branch changes. In addition, a backup copy of your feature changes will be pushed out to origin. This backup should not be used to collaborate with others. It is just a personal backup and will be deleted and recreated with each rebase.

feature rebase

For example, rkiel-master-my-new-feature will be pushed out to origin.

Merge

Use the merge subcommand to merge your feature branch changes to the standard branch.

feature merge

You can also override the default standard branch by specifying another branch.

feature merge integration

Commit

Use the commit subcommand to make it easier to write commit messages. No need to specify the -m parameter or wrapping the message in quotes. If you forget and pass in -m anyway, it will ignore it. For example,

feature commit this is a sample commit message
feature commit -m this is a sample commit message

generates the command git commit -m "this is a sample commit message".

The commit message will be prepended with the feature name. For example,

my-feature-name: this is a sample commit message

End

Use the end subcommand to safely close out the feature. The standard branch will be checkout and the local feature branch will be deleted. This command will fail if you have not merged your changes. If successful and there is a backup copy on origin, it will also be removed.

feature end

Trash

Use the trash subcommand to forcibly close out the feature. The standard branch will be checkout and the local feature branch will be forcibly deleted. Make sure that your changes have been merged because they will be lost. If there is a backup copy on origin, it will also be removed.

feature trash

Xgrep utility

This utility makes it easier to use git-grep.
