GDM 0.5

A language-agnostic "dependency manager" using Git.

Getting Started

Git Dependency Manager (GDM) is a language-agnostic “dependency manager” using Git. It aims to serve as a submodules replacement and provides advanced options for managing versions of nested Git repositories.

Requirements

• Python 3.3+

• Latest version of Git (with stored credentials)

• OSX/Linux (with a decent shell for Git)

Installation

GDM can be installed with pip:

$ pip3 install gdm

or directly from the source code:

$ git clone https://github.com/jacebrowning/gdm.git
$ cd gdm
$ python3 setup.py install

Setup

Create a GDM configuration file (gdm.yml or .gdm.yml) in the root of your working tree:

location: .gdm
sources:
- repo: https://github.com/kstenerud/iOS-Universal-Framework
  dir: framework
  rev: Mk5-end-of-life
- repo: https://github.com/jonreid/XcodeCoverage
  dir: coverage
  rev: master
  link: Tools/XcodeCoverage

Ignore GDM’s dependency storage location:

$ echo .gdm >> .gitignore

Basic Usage

See the available commands:

$ gdm --help

Updating Dependencies

Get the latest versions of all dependencies:

$ gdm update

which will essentially:

1. create a working tree at root/location/dir

2. fetch from repo and checkout the specified rev

3. symbolically link each location/dir from root/link (optional)

4. repeat for all nested working trees containing a configuration file

5. record the actual commit SHAs that were checked out

where rev can be:

• all or part of a commit SHA: 123def

• a tag: v1.0

• a branch: master

• a rev-parse date: 'develop@{2015-06-18 10:30:59}'

Restoring Previous Versions

Display the specific revisions that are currently installed:

$ gdm list

Reinstall these specific versions at a later time:

$ gdm install

Deleting Dependencies

Remove all installed dependencies:

$ gdm uninstall
