Parse Ruby Gemfile, .gemspec and Cocoapod .podspec files using Python.

Project description

gemfileparser parses Ruby Gemfile using Python with supports Ruby Gemfiles and .gemspec files as well as Cocoapod .podspec files.


In a virtualenv, use the command:

pip install gemfileparser

Otherwise from a git clone, use the following commands in a virtualenv:

git clone
cd gemfileparser
    python install


from gemfileparser import GemfileParser
parser = GemfileParser(<path to Gemfile>, <name of the application (optional)>)
dependency_dictionary = parser.parse()

The parse() method returns a dict object of the following format:

    'development': [list of dependency objects inside group 'development'],
    'runtime': [list of runtime dependency objects],

Each dependency object contains the following attributes:

  • name - Name of the gem
  • requirement - Version requirement
  • autorequire - Autorequire value
  • source - Source URL of the gem
  • parent - Dependency of which gem
  • group - Group that a gem is a member of (default : runtime)


from gemfileparser import GemfileParser
n = GemfileParser('Gemfile', 'diaspora')
deps = n.parse()
for key in deps:
   if deps[key]:
       print key
       for dependency in deps[key]:
           print("\t", dependency)


Do this to run tests:

pip install -e .
pip install pytest
pytest -vvs tests
