Installation
*************

Install from `PyPI`_:

::

$ pipenv install --pre requirementslib

Install from `Github`_:

::

.. _`Summary`:

Summary
********

RequirementsLib provides a simple layer for building and interacting with
requirements in both the `Pipfile <https://github.com/pypa/pipfile/>`_ format
and the `requirements.txt <https://github.com/pypa/pip/>`_ format. This library
was originally built for converting between these formats in `Pipenv <https://github.com/pypa/pipenv>`_.

.. _`Usage`:

Usage
******

Import the library and create a requirement object from *requirements.txt* format:

::

>>> from requirementslib import Requirement
>>> r = Requirement.from_line('-e git+https://github.com/pypa/pipenv.git@master#egg=pipenv')
>>> print(r)
Requirement(name='pipenv', vcs='git', req=VCSRequirement(editable=True, uri='git+https://github.com/pypa/pipenv.git', path=None, vcs='git', ref='master', subdirectory=None, name='pipenv', link=<Link git+https://github.com/pypa/pipenv.git@master#egg=pipenv>, req=<Requirement: "-e git+https://github.com/pypa/pipenv.git@master#egg=pipenv">), markers=None, specifiers=None, index=None, editable=True, hashes=[], extras=[])

>>> r.as_pipfile()
{'pipenv': {'editable': True, 'ref': 'master', 'git': 'https://github.com/pypa/pipenv.git'}}


Or move from *Pipfile* format to *requirements.txt*:

::

>>> r = Requirement.from_pipfile(name='pythonfinder', indexes=[], pipfile={'path': '../pythonfinder', 'editable': True})
>>> r.as_line()
'-e ../pythonfinder'
