git mob

CLI app to help you automatically add Co-authored-by trailers to git commits during pair/mob programming

You can attribute a git commit to more than one author by adding one or more Co-authored-by trailers to the commit's message. Co-authored commits are visible on GitHub. For more information, see here.

This CLI app will help you add them automatically and also help you store and manage co-authors for pair/mob programming sessions.

Features

• Cross-platform
• Co-authors management via CLI
• Multi-select menu to choose co-author(s) for mobbing
• Automatic appending of Co-authored-by trailers to commit
• No need of any git aliases

Installation

Prerequisites

• Git

With Binary Package:

• Download and extract the appropriate binary depending on your OS from the latest GitHub release
• Ensure the binary is in your PATH variable e.g. you may place the file in C:\Windows on Windows or /usr/local/bin on Linux and macOS
• Ensure the binary is set as executable (Linux and macOS)

  $ chmod +x ./git-mob
  

With Cargo:

• Install Rust
• If you are using Windows, you will also need to install certain C++ build tools

$ cargo install git-mob-tool

Configuration

• Store your team members' details with keys (usually initials)

  $ git mob coauthor --add lm "Leo Messi" leo.messi@example.com
  $ git mob coauthor --add em "Emi Martinez" emi.martinez@example.com
  $ git mob coauthor --add sa "Sergio Aguero" sergio.aguero@example.com
  ...
  

• Set a global githooks directory

  $ mkdir ~/git
  $ git config --global core.hooksPath "~/git"
  

• Download the prepare-commit-msg file into the directory

• Ensure it is set as executable (Linux and macOS)

  $ chmod +x ./prepare-commit-msg
  

  This githook will be used to append the Co-authored-by trailers to the commit's message.

  This githook also adds a Jira Issue ID as a prefix to the commit message if the branch name starts with a string resembling one. If you don't want want this, comment out line 42 which calls the function add_jira_issue_id_prefix.

Usage

• To mob with some team member(s):

  $ git mob --with
  ? Select active co-author(s):
  > [ ] Leo Messi <leo.messi@example.com>
    [ ] Emi Martinez <emi.martinez@example.com>
    [ ] Sergio Aguero <sergio.aguero@example.com>
  [↑↓ to move, space to select one, → to all, ← to none, type to filter ]
  

  Alternatively, if you remember the co-author keys, you may bypass the multi-select menu by running:

  $ git mob --with lm em
  

  This will start a global mob session. Any git commit made afterwards will have Co-authored-by trailers added to the commit message as shown below:

  This is an example commit message
  
  Co-authored-by: Leo Messi <leo.messi@example.com>
  Co-authored-by: Emi Martinez <emi.martinez@example.com>
  

• To clear the mob session:

  $ git mob --clear
  

• To view the co-authors in the current mob session:

  $ git mob --list
  

• To print help information:

  $ git mob help
  $ git mob help coauthor
  

Troubleshooting

• Try installing the latest version of git
