Pipfile

Warning: this project is under active development.

A Pipfile is a new (and much better!) way to declare dependencies for your Python environment, e.g. deployment of a web application. 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": "..."},
    ]
}
