pyproject2setuppy -- a cheap build for pyproject.toml-based systems

pyproject2setuppy is a tool to install pyproject.toml-based packages using plain setuptools. It maps the project metadata into setup() call arguments, making it possible to build them without installing the dependency hell of the new build systems.

Supported features

Currently the following build systems are supported:

flit
poetry

Only minimal build/install functionality is supported. Dependencies and sdist-related information are not propagated.

Scripts and entry points are not supported at the moment. This is subject to change in the future.

Unlike the upstream build systems, this package has been tested to work correctly both with Python 2.7 and Python 3.4+.

Dependencies

The runtime (and build time, if using setup.py) dependencies are:

toml (to read pyproject.toml)
setuptools (to provide fully-featured setup.py commands)

Testing

The package provides unittest-compatible test suite. However, due to setuptools output it is recommended to run them using pytest:

$ pytest -vv

Testing on Python 2 requires additional compatibility modules installed:

Installation

pyproject2setuppy is using a flit-compliant pyproject.toml. It includes setup.py that uses itself to maintain setuptools compatibility. Note that the latter does not install package's dependencies.

Usage

In order to use pyproject2setuppy to build a pyproject.toml-based project, either copy the included setup.py to the project's directory or call the entry point directly, e.g.:

$ python -m pyproject2setuppy.main build
