Features

• Manage the co-authorship of commits by automatically writing appropriate* Co-authored-by trailers (see link for details on this standard)
• Take co-authorship information written in the first line of the commit message and convert that into appropriate Co-authored-by trailers (overrides all other sources)
• Ensure that the author drafting the commit is not duplicated as a Co-authored-by trailer
• Preserve co-authorship information when ammending commits

Installation

The simplest way to install xp in your dev environment is:

go get -u github.com/kidoman/xp

brew will be added as an option at a later date.

Usage

xp stores its global configuration at ~/.xp (can be overriden via global flag --config)

Most of the xp functionality are exposted via various subcommands:

• show-config (sc): Print the current stored configuration
• dev (d): Add/remove developers in xp
• repo (r): Add/remove repos managed by xp

A separate command add-info is made available for use from within git hooks:

• prepare-commit-msg
• commit-msg

Example

Suppose we have a repo at ~/work/lambda which we want to now manage using xp (this assumes you have already installed xp using the instructions above):

Add Karan Misra <[email protected]> as a tracked author in the system with shortcode "km" to allow for easy referencing in future command line invocations or the first line of commit messages. Same for "akshat":

$ xp dev add km "Karan Misra" [email protected]
$ xp dev add ak "akshat" [email protected]

Switch to the directory with the git repo:

$ cd ~/work/lambda

Initialize the git hooks and register the repo with xp:

$ xp repo init .

Indicate that akshat is pairing with you by adding him using his shortcode:

$ xp repo dev ak

Commit as normal:

$ touch CHANGE
$ git add .
$ git commit -m"Added CHANGE"

Rejoice at a well formed commit message:

$ git log -1
commit c4700d32046d94070de0c160eb35b2090973b507 (HEAD -> master)
Author: Karan Misra <[email protected]>
Date:   Thu Mar 7 03:04:25 2019 +0530

    Added CHANGE

    Co-authored-by: akshat <[email protected]>

Bonus

If you quickly want to author a commit with someone you typically don't pair with:

$ xp dev add as "Anand Shankar" [email protected]

After making the required changes:

$ git add .
$ git commit -m"[as] Make world better"

The commit message becomes:

$ git log -1
commit d4710d32046d94070de0c160eb35b2091973b507 (HEAD -> master)
Author: Karan Misra <[email protected]>
Date:   Thu Mar 7 03:12:21 2019 +0530

    Make world better

    Co-authored-by: Anand Shankar <[email protected]>

Note: See how the [as] from the start of the commit message has now resulted in Anand Shankar being added as a co-author, overriding the repo level setting (thus akshat is not in the list anymore.) Multiple co-authors can be similarly added by separating their aliases by , or | like so:

$ git commit -m"[anand,akshat] Make world better"
$ git commit -m"[anand|akshat] Make world better"
