importreqs

A simple Python lib for extracting reqs.txt from currently imported libs in the context. The lib can be used in the following scenarios:

Gathering the dependencies for serverless frameworks such as AWS Lambda. If several functions share the same virtualenv, unused dependecies may be introduced via pip freeze. Use importreqs will expose only the reqs imported.
Remove unused dependencies after refactoring, or on a long time maintained projects.

Install

pip install importreqs

To use importreqs:

import importreqs
importreqs.generate_reqs(replace_version_hash=False,
                         exclude=None)

replace_version_hash: For editable reqs(with -e when using pip install), remove the commit hash from result.
exclude: Exclude listed packages from the result. For example, importreqs itself.

For example:

# import your own projects
# for example "import app"

import importreqs

print(importreqs.generate_reqs(exclude=['importreqs']))

Or use importreqs from command line:

importreqs -c "import requests"
