Action should publish newly tagged releases to PyPI

[simonw]

This works for running tests. I'm spinning off a separate issue for getting the action to publish new tags as PyPI releases if the PYPI_TOKEN environment variable is set.

I think this needs if: secrets.PYPI_TOKEN in the step.

This should be documented in the README.

[simonw]

You create PyPI tokens for publishing to a repo at https://pypi.org/manage/account/token/

[simonw]

Looks like you need to create a token with "Entire account (all projects)" permission in order to publish the original package. Then you can replace that token with one that just has scoped access to the package.

I created one of those and added it as the PYPI_TOKEN secret to https://github.com/simonw/datasette-plugin-template-demo/settings/secrets

I'm going to try this action: https://github.com/actions/starter-workflows/blob/master/ci/python-publish.yml

Documented here: https://help.github.com/en/actions/language-and-framework-guides/using-python-with-github-actions#publishing-to-package-registries suggests

But I'm going to have it re-run the tests first.

I tried creating a new release in datasette-plugin-template-demo and got this error:

https://github.com/simonw/datasette-plugin-template-demo/actions/runs/141395948

The workflow is not valid. .github/workflows/publish.yml (Line: 30, Col: 11): Unrecognized named-value: 'secrets'. Located at position 14 within expression: success() && secrets.PYPI_TOKEN

Referring to this line:

https://github.com/simonw/datasette-plugin/blob/b2a601b9c8b116dfbee11594ed76f113ebf4d6b0/datasette-%7B%7Bcookiecutter.hyphenated%7D%7D/.github/workflows/publish.yml#L29-L33

[simonw]

I'll try adding ${{ <context> }}

It worked! https://pypi.org/project/datasette-plugin-template-demo/0.1/

Just needs documentation now.
