pipfreeze

A tool to audit pip freeze outputs and test version requirements.

This tool can be used to audit the pip freeze output of a virtualenv and check whether a specific version of a package is installed, or a version that matches a given version range.

Install

pip insall pipfreeze

Usage

from pipfreeze import PipFreeze
from pkg_resource import Requirement

pip_freeze_output = """\
foo==1.2.3
bar==2.0
"""

pip_freeze = PipFreeze(pip_freeze_output)

# Check if foo v2 or greater is installed
req = Requirement.parse('foo>=2.0')
assert pip_freeze.satisfies_requirement(req) is False

# Check if foo 1.2.3 is installed
req = Requirement.parse('foo==1.2.3')
assert pip_freeze.satisfies_requirement(req) is True

# Check if any version of foo 1.x is installed
req = Requirement.parse('foo>=1.0.0,<2.0.0')
assert pip_freeze.satisfies_requirement(req) is True

# Check if any version of zoo is installed
req = Requirement.parse('zoo')
assert pip_freeze.satisfies_requirement(req) is None
