Publish Anaconda Package

A Github Action to build and optionally publish your software package to an Anaconda repository.

Default behaviour

All of the input variables and defaults can be found in action.yml

The default settings result in the default behaviour being that the package is built and tested for linux with numpy=1.18 and python=3.7, but not published.

If publish is set to True, then this single variant is published.

For all variants to be built, tested, and (if publish is True) published, test_all must be set to True.

Example workflow

This workflow has the following behaviour:

When pushing to main all variants are built and tested.

• If pushing to main, all variants are built and tested.
• If an annotated tag is created, all variants are built, tested and published.
• If opening or modifying a pull request to main, a single variant is built and tested, but not published.
• Builds using channels: conda-forge, and ccpi.
• Builds for linux and conda converts to windows and macOS as well.

ANACONDA_TOKEN

1. Get an Anaconda token (with read and write API access) at anaconda.org/USERNAME/settings/access
2. Add it to the Secrets of the Github repository as ANACONDA_TOKEN

Build Channels

By Default, this Github Action will search for conda build dependancies (on top of the standard channels) in conda-forge and bioconda
