Script used to publish GitHub release notes extracted from CHANGELOG.rst.
|
||||
Script used to generate a Markdown file containing only the changelog entries of a specific pytest release, which
|
||||
is then published as a GitHub Release during deploy (see workflows/deploy.yml).
|
||||
|
||||
This script is meant to be executed after a successful deployment in GitHub actions.
|
||||
|
||||
Uses the following environment variables:
|
||||
|
||||
* GIT_TAG: the name of the tag of the current commit.
|
||||
* GH_RELEASE_NOTES_TOKEN: a personal access token with 'repo' permissions.
|
||||
|
||||
Create one at:
|
||||
|
||||
https://github.com/settings/tokens
|
||||
|
||||
This token should be set in a secret in the repository, which is exposed as an
|
||||
environment variable in the main.yml workflow file.
|
||||
|
||||
The script also requires ``pandoc`` to be previously installed in the system.
|
||||
The script requires ``pandoc`` to be previously installed in the system -- we need to convert from RST (the format of
|
||||
our CHANGELOG) into Markdown (which is required by GitHub Releases).
|
||||
|
||||
Requires Python3.6+.
