DepEx

Extract Python project dependencies from a pyproject.toml file.

Why?

I haven't completely dropped requirements.txt and requirements-dev.txt files yet so this helps me keep them in sync with the dependencies I have listed in the pyproject.toml file.

Usage

Just provide the path to a Python project directory or a pyproject.toml file and extract base dependencies, optional dependencies, or all dependencies from the pyproject.toml file.

# generate a file with only the base dependencies of a package
$ depex --no-opts > requirements.txt

# or generate a file with all dependencies (including optional) of a package
depex > requirements-dev.txt

Help

$ depex -h
usage: depex [-h] [--opts | --no-opts] [--version] path
