is-new-version

a github action to check if the current new version is already exists as a git tag. It checks the version in a pyproject.toml file, and if a tag of the version does not exist, it states so in its output. It also fetches the release notes from a changelog.

Example

An example workflow that uses this action to check for new tags and release a new version if it is new:

name: Release new tags
on:
    push:
        branches:
            - main

jobs:
    check-tag:
        name: check for new tags
        runs-on: ubuntu-latest

        steps:
            - name: check for new version
              id: check-version
              uses: biocatchltd/gh-actions-is-new-version@latest

            - name: release a new version
              if: steps.check-tag.outputs.is-new == 'true'
              uses: softprops/action-gh-release@v2
              with:
                body: ${{ steps.check-version.outputs.release-notes }}
                tag_name: ${{ steps.check-version.outputs.found-version }}
                target_commitish: ${{ github.sha }}
                prerelease: ${{ steps.check-tag.outputs.is-prerelease }}

inputs

• toml-path: the path to the TOML file to use to determine the version, default to pyproject.toml
• changelog-path: the path to the markdown file to use to determine the version, default to CHANGELOG.md
• release-prefix: the prefix to be added to the release tag, default to an empty string

outputs

• is-new: whether the step detected a new version
• found-version: the version detected by the action
• release-notes: the markdown snippet of the release notes of the version, will be blank if no version is not new
• is-prerelease: whether the version is detected as a pre-release (currently, all versions with a - in them are considered pre-releases). Will be blank if no version is not new.
• release-tag: the full tag of the release, including the prefix
