requirementslib 0.0.5

A tool for converting between pip-style and pipfile requirements.

Installation

Install from PyPI:

$ pipenv install --pre requirementslib

Install from Github:

$ pipenv install -e git+https://github.com/techalchemy/requirementslib.git#egg=requirementslib

Summary

RequirementsLib provides a simple layer for building and interacting with requirements in both the Pipfile format and the requirements.txt format. This library was originally built for converting between these formats in Pipenv.

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'
