Tooling for Git

This repository contains useful commands for common Git-related tasks.

Description

All the commands follow the well-established Git philosophy to provide rather simpler, but versatile building blocks for more complex tasks. The commands are most useful when combined effectively (see some recipes below). Following commands are currently available:

• git-author-rewrite: replaces author/committer in Git history
• git-ext-each: lists all repositories in a directory tree and optionally executes an action
• git-ext-exec: executes a command for all repositories from the given list
• git-ext-init: sets up new repository according to Multi-Version Flow.
• git-ext-test: provides convenient tests for the most common cases

All tools provide -h or --help options to display usage details. Note that the commands are meant for humans and therefore may evolve and change, including their parameters.

Installation

There is no actual installation, the commands can be run without additional actions, assuming that Git and Bash are available. However, it is convenient to adjust the PATH environment variable to include the location of the commands. Including the location in PATH triggers partial shell completion support and turns the scripts into Git commands (although with some limitations).

Recipes

Imagine having a workspace with a couple of repositories. Here are a few common tasks that you might want to perform:

# List all repositories with uncommitted changes
$ git-ext-each | git-ext-test --not is-clean

# Execute 'git pull' on all repositories
$ git-ext-each | git-ext-exec git pull

The nice thing of git-ext-exec is that it allows you providing the command to execute as a verbatim text, which makes composed commands with many special characters much easier:

$ git-ext-each | git-ext-test at-branch feature/XYZ | git-ext-exec 'git flow feature finish && git push'

Conditional listing all repositories is a frequent operation and many bulk actions start with it. Therefore it may be useful to add to your .bashrc something like:

function git-list-if () {
    git-ext-each | git-ext-test "$@"
}

The previous example can be then simplified a bit:

$ git-list-if at-branch feature/XYZ | git-ext-exec 'git flow feature finish && git push'
