Yippee

Manage requirements.txt files

Using requirements.txt files makes it hard to distinguish between top-level dependencies and transient dependencies. In addition, separating out different dependencies for multiple environments is challenging. Yippee attempts to ease the pain by specifying a DSL by which requirements.txt files can be generated.

For example, with the following yippee.py file:

from yippee import group, pip

pip("django", ">=2.1.0")

with group("production"):
    pip("postgres", "2.2.2")

with group("development"):
    pip("black")

This would generate:

requirements.txt

Django==2.1.5
pytz==2018.7

requirements-production.txt

-r requirements.txt
postgres==2.2.2
psycopg2-binary==2.7.6.1

and

requirements-development.txt

-r requirements.txt
appdirs==1.4.3
attrs==18.2.0
black==18.9b0
Click==7.0
toml==0.10.0

Usage

Install yippee via pypi. Then you can run yippee to generate your requirements.txt files.
