GitMan 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.





Install GitMan with pip:

$ pip install gitman

or directly from the source code:

$ git clone https://github.com/jacebrowning/gitman.git
$ cd gitman
$ python setup.py install


Generate a sample configuration file:

$ gitman init

or manually create one (gitman.yml or .gitman.yml) in the root of your working tree:

location: vendor/gitman
- name: framework
  repo: https://github.com/kstenerud/iOS-Universal-Framework
  rev: Mk5-end-of-life
- name: coverage
  repo: https://github.com/jonreid/XcodeCoverage
  rev: master
  link: Tools/XcodeCoverage
- name: trufflehog
  repo: https://github.com/dxa4481/truffleHog
  rev: master
  - chmod a+x truffleHog.py

Ignore the dependency storage location:

$ echo vendor/gitman >> .gitignore


See the available commands:

$ gitman --help

Updating Dependencies

Get the latest versions of all dependencies:

$ gitman update

which will essentially:

  1. Create a working tree at <root>/<location>/<name>
  2. Fetch from repo and checkout the specified rev
  3. Symbolically link each <location>/<name> from <root>/<link> (if specified)
  4. Repeat for all nested working trees containing a configuration file
  5. Record the actual commit SHAs that were checked out (with --lock option)
  6. Run optional post-install scripts for each dependency

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:

$ gitman list

Reinstall these specific versions at a later time:

$ gitman install

Deleting Dependencies

Remove all installed dependencies:

$ gitman uninstall
