Multi Git

A Git command line to manage multiple git repositories at once.

Intended use

If you ever worked in a micro service environment, you've most likely been asked to worked with dozen of projects. Keeping them up to date tends to be tedious.

This module aims to replace this :

$ cd group/project1
$ git pull
$ cd ../project2
$ git pull
$ cd ../project3
$ git pull
$ cd ../project4
$ git pull
$ cd ../project5
$ git pull
...

by that :

$ cd group
$ multi-git pull

same goes for status, fetch ...

Configuration

multi-git will try to read its configuration file from multiple locations in the following order:

1. the current working directory
2. the home directory
3. the module directory (which will most likely serve as default values)

This file must be named .mg-config.json and be in json format.

{
    "defaultToProject": false,
    "defaultGroupSettings": {
        "allowEmptyRelease": true
    },
    "projects": {
        "repo1": {
            "name": "repo1",
            "path": "/home/ubuntu/workspace/repos/repo1"
        },
        "repo2": {
            "name": "repo2",
            "path": "/home/ubuntu/workspace/repos/repo2"
        },
        "repo3": {
            "name": "repo3",
            "path": "/home/ubuntu/workspace/repos/repo3"
        }
    },
    "groups": {
        "awesome-group": {
            "name": "awesome-group",
            "allowEmptyRelease": false,
            "members": [
                "repo1",
                "repo2"
            ]
        },
        "magnificent-group": {
            "name": "magnificent-group",
            "members": [
                "repo2",
                "repo3"
            ]
        }
    }
}

• Paths can be absolute or relative.
  • If relative, they will be resolved from the current working directory.
• Paths can contain ~
• A project can belong to multiple groups

About allowEmptyRelease

By default, if you attemp to run multi-git release start on a group, it will run git flow release start for each project, wether or not develop is ahead of master. Wich means you could create empty release. A group with allowEmptyRelease set to false, will skip such directories.

Behaviour

You can use multi-git:

• with the --group flag: In that case multi-git will try to find the group by its name in the configuration file and run the specified command on each group member.
• with the --project flag: In that case multi-git will try to find the project by its name in the configuration file and run the specified command.
• without either of those:
  • if config.defaultToProject === true: multi-git will run the specified command in the current working directory, just like git would.
  • otherwise:
    • if the current working directory is a git repository, multi-git will run the specified command on each member of each group the cwd belongs ;
    • if not, it will run the command on each subdirectories of the cwd.
