一种新的方式来声明Python应用程序的依赖关系

一种新的方式来声明Python应用程序的依赖关系

Pipfile

Warning: this project is under active development.

A Pipfile is a new (and much better!) way to declare dependencies for your Python applications. It will be a full replacement for the well-pervasive requirements.txt files, currently installable with $ pip install -r.

The Concept

A Pipfile will be superior to a requirements.txt file in a number of ways:

Expressive Python syntax for declaring all types of Python dependencies.Grouping of sub-dependency groups (e.g. a testing group).Use of a single file only will be extremely encouraged.Pipfile.lock

Example Pipfile

Note—this is an evolving work in progress:

# Note: There will be a default source, and context manager can also be used.source('https://pypi.org/', verify_ssl=True)package('requests')package('Django', '==1.6')package('pinax', git='git://github.com/pinax/pinax.git', ref='1.4', editable=True)with group('development'): package('nose')

Example Pipfile.lock

Note—this file is always to be generated, not modified or constructed by a user:

{ "_meta": { "sources": [ {"url": "https://pypi.org/", "verify_ssl": true}, ] }, "default": [ {"name": "requests", "version": "0.11.2", "hash": "..."}, {"name": "Django", "version": "1.6", "hash": "..."}, {"name": "pinax", "git": "git://...", "ref": "1.4", "editable": true}, ], "development": [ {"name": "nose", "version": "1.3.7", "hash": "..."}, ]}

Documentation

The documentation for this project will (eventually) reside at pypi.org.
