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