This adds a new subcommand to git to build integration branches. It does this by doing a sequence of commands:

1. Fetch all updates from all remote repositories configured.
2. Create or reset the branch passed in using origin/master as the base.
3. Merge each branch that has a pull request that is labeled with the label passed to the command. This is done in the order in which the pull requests have been created from oldest to newest.

If you encounter a merge conflict; resolve it, then run git commit --no-edit, and finally re-run git integrate $LABEL $BRANCH again. When done merging everything the tool should be on the resulting branch ready to be pushed.

For easier and more reliable results enable git-rerere. This will help reduce the number of merge conflicts that have to be fixed.

Installing git-integrate is straightforward!

1. Install rust for your system if you have not done so
2. Ensure Cargo is added to your $PATH and restart your terminal
3. Install git-integrate by running

cargo install --force --path .

4. Then follow the steps below in Configuration

Get a GitHub token and select repo - Full control of private repositories for the scope if you want to use it with private repositories. Then either modify your ~/.gitconfig file and add the following:

[integrate]
  github-token = <insert token here>

Or you can just run the following command:

git config --global integrate.github-token <insert token here>

git-integrate uses git rerere to resolve merge conflicts. To enable rerere, add the following to your project's config in <project_root>/git/config:

[rerere]
  enabled = true

Or run the following command:

git config --local rerere.enabled true

To add the setting globally instead, run the following command:

git config --global rerere.enabled true

Simple scenario:

# Parameters
git integrate MILESTONE BRANCH

# Example
git integrate 1024 release-candidate/1986-06-14-000
git push --force origin deploy/staging

Merge Conflict:

git integrate 1024 release-candidate/1986-06-14-000

# Fix merge conflict here

git commit --no-edit
git integrate 1024 release-candidate/1986-06-14-000
git push --force origin deploy/staging
