Annotate your Python requirements.txt file with a short summary of each package.

This tool:

• takes a Python requirements.txt file as input
• fetches the summary of each package from the PyPi registry
• outputs an equivalent requirements list with added comments summarizing each package

It can be used as a Python module or a command line script.

Before:

black==21.9b0
gunicorn==20.1.0
pytz==2021.3
requests==2.26.0
rope==0.20.1
whitenoise==5.3.0

After:

black==21.9b0                            # The uncompromising code formatter.
gunicorn==20.1.0                         # WSGI HTTP Server for UNIX
pytz==2021.3                             # World timezone definitions, modern and historical
requests==2.26.0                         # Python HTTP for Humans.
rope==0.20.1                             # a python refactoring library...
whitenoise==5.3.0                        # Radically simplified static file serving for WSGI applications

Note: This is not a published package yet. For now:

git clone https://github.com/zeke/summarize-requirements
cd summarize-requirements

The CLI reads a requirements file as input and prints summarized results as output. It does not overwrite the existing file.

If you run the command with no arguments, it'll look for requirements.txt in the current directory:

python index.py

Or you can specify a different file:

python index.py ~/path/to/your/requirements.txt > new-requirements.txt

from summarize import summarize

for line in summarize('requirements.txt'):
    print(line)
