snapADDY Changelog Parser

A Github Action to parse manually created changelogs for automatic Github Releases.

This action reads a markdown changelog file, and provides the latest versions release notes to steps further down the pipeline.

Simple example:

on:
  push:
    tags:
      - "[0-9]+.[0-9]+.[0-9]+"

jobs:
  tagged-release:
    name: "Tagged Release"
    runs-on: "ubuntu-latest"

    steps:
      - name: Read Changelog
        uses: snapADDY/[email protected]
        id: read
      - name: Release
        uses: softprops/action-gh-release@v1
        with:
          body: ${{ steps.read.outputs.changelog }}
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Required changelog formatting:

Each section hast to start with a # followed by a space (markdown H1) and a semver formatted version number. Brackets around the version number are also supported, in case it's a hyperlink.

# 1.0.0
or
# [1.0.0](https://)

Example:

This input:

# [1.0.0](https://github.com/...) (2021-04-30)
## Features
- CI Magic 🧙‍♂️

# [0.1.0](https://github.com/...) (2021-04-27)
## Fixes
- more notes

would return:

## Features
- CI Magic 🧙‍♂️
