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 https://github.com/gemfileparser/gemfileparser.git
cd gemfileparser
python setup.py 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
