This magoo is Magoo, he helps you manage git submodules with ease, like npm or cargo, but for submodules.

Adding a submodule is easy, but have you ever struggled with:

  • How do I update a submodule?
  • How do I delete a submodule?
  • How do I tell my colleagues how to update their submodules after I update them????

magoo saves all of us by running the git commands for us. He figures out all the relevant information from the git repository itself. There's no extra files required and magoo works out of the box for all git repos with submodules.

magoo does not like pipelines. Please simply let your pipeline checkout the submodules (recursively if needed). For example, if you are using GitHub Actions:

- uses: actions/checkout@v4
    submodules: recursive

Install magoo

magoo As a CLI tool

cargo install magoo

magoo As a library

To add magoo as a dependency:

cargo add magoo

See https://docs.rs/magoo for more info.

Use magoo

magoo runs git commands using sub-processes, so you must have git installed on the system. To check the version info, run

magoo status --git

Unsupported versions might work as well, magoo just doesn't know.

git <=2.42.0 doesn't work due to a bug in set-branch and set-url commands

Add a submodule

magoo install URL PATH

(magoo install --help to see a full list of options)

The arguments for adding a submodule is very similar to git submodule add

magoo needs to know the following to add a submodule.:

Arg Description Default
URL The git URL like https://github.com/owner/repo. SSH and relative URLs also work. See git submodule add for details URL is required
PATH The path in your repo the module should be at Directory at the top level with the same name as the submodule repo
BRANCH The branch to update to when you run magoo update None (HEAD)
NAME Name to identify the submodule for other commands same as PATH

It's recommended to always specify the BRANCH. Git by default will use the HEAD branch, which is usually not what you want.

Initialize/pull the submodules

magoo install

magoo will ensure the submodules are cloned/updated to the commit stored in the index. You should run magoo install every time you pull the changes from others, in case they were updated. It also deletes submodules that are deleted by others (by running status --fix, see below).

Show submodule status

magoo status [--long] [--fix]

magoo will show you everything he knows about submodules in the current repo.

The --fix option will bring the submodule states back to a consistent state that magoo likes. The state could be inconsistent if the git files were changed manually or by running individual git commands, or by a remote change.

magoo will fix the state by either de-initializing the submodule (if possible), or delete the submodule.

Update submodules

magoo update

This tells magoo to update all submodules to be sync with the remote BRANCH (specified when submodule was added). See magoo update --help for more info.

You can also:

  • Update one submodule to the latest
    magoo update NAME
  • Change the branch and/or URL of a submodule
    magoo update NAME --branch BRANCH --url URL

Remove submodules

magoo remove NAME

magoo will remove every trace of the submodule, with this single command.

Note: Newer versions of git lets you delete a submodule with git rm. However, it doesn't delete the content in .git/modules. magoo deletes those as well.
