Build conda packages directly from pure python wheels

whl2conda

Generate conda packages directly from pure python wheels

whl2conda is a command line utility to build and test conda packages generated directly from pure python wheels.

• Performance: because it does not need to create conda environments in order to build, this is much faster than solutions involving conda-build.

• Dependency renaming: renames pypi package dependencies to their corresponding conda name. Automatically renames packages from known list collected from conda-forge and supports user-specified rename patterns as well.

• Multiple package formats: can generate both V1 ('.tar.bz2') and V2 ('.conda') conda package formats. Can also generate a unpacked directory tree for debugging or additional user customization.

• Project configuration: whl2conda project-specific options can be read from project's pyproject.toml file.

• Test install support: supports installing conda package into a conda environment for testing prior to deployment.

• Hides pypi dependencies: rewrites the original pip/pypi dependencies in the installed dist-info to avoid compatibility issues.

Installation

With pip:

pip install whl2conda

With conda (upcoming):

conda install -c conda-forge whl2conda

Quick usage

Generate a conda package in same directory as wheel file:

whl2conda build dist/mypackage-1.2.3-py3-none-any.whl

Add default tool options to pyproject.toml

whl2conda config --generate-pyproject pyproject.toml

Build both wheel and conda package for project:

whl2conda build --build-wheel my-project-root

Create python 3.10 test environment for generated conda package:

whl2conda install dist/mypackage-1.2.3.-py_0.conda --create -n testenv \
  --extra pytest python=3.10
