Christopher Sexton becafb2f61 Include body parameter for release
Fixes #4

This adds the ability to include the body parameter when creating the
release.

    - name: Checkout code
      uses: actions/checkout@master
    - name: Create Release
      id: create_release
      uses: actions/create-release@master
      with:
        tag_name: ${{ github.ref }}
        release_name: Release ${{ github.ref }}
        body: Release body

This also supports a multiline body:

    - name: Create Release
      id: create_release
      uses: actions/create-release@master
      with:
        tag_name: ${{ github.ref }}
        release_name: Release ${{ github.ref }}
        body: |
          This is a multiline body
          with more than one
          line

Or if you want the contents of a file:

    - name: Read CHANGELOG
      id: changelog
      run: |
        echo "::set-output name=body::$(cat CHANGELOG.md)"
    - name: Create Release
      id: create_release
      uses: actions/create-release@master
      with:
        release_name: Release ${{ github.ref }}
        body: ${{ steps.changelog.outputs.body }}

One decision I made in favor of less code was to send an empty body when
there was non present. If it would be preferred to send nothing in the
request for the `body` attribute I could instead compose the parameters
with an optional body attribute:

    releaseParams = {
      owner,
      repo,
      tag_name: tag,
      name: releaseName,
      draft,
      prerelease
    };

    if (body) releaseParams.body = body;

    const createReleaseResponse = await github.repos.createRelease( releaseParams );

# GitHub Action - Releases API
This GitHub Action (written in JavaScript) wraps the [GitHub Release API](https://developer.github.com/v3/repos/releases/), specifically the [Create a Release](https://developer.github.com/v3/repos/releases/#create-a-release) endpoint, to allow you to leverage GitHub Actions to create releases.
<a href="https://github.com/actions/create-release"><img alt="GitHub Actions status" src="https://github.com/actions/create-release/workflows/Tests/badge.svg"></a>
## Usage
### Pre-requisites
Create a workflow `.yml` file in your repositories `.github/workflows` directory. An [example workflow](#example-workflow---create-a-release) is available below. For more information, reference the GitHub Help Documentation for [Creating a workflow file](https://help.github.com/en/articles/configuring-a-workflow#creating-a-workflow-file).
### Inputs
For more information on these inputs, see the [API Documentation](https://developer.github.com/v3/repos/releases/#input)
- `tag_name`: The name of the tag for this release
- `release_name`: The name of the release
- `body`: Text describing the contents of the release
- `draft`: `true` to create a draft (unpublished) release, `false` to create a published one. Default: `false`
- `prerelease`: `true` to identify the release as a prerelease. `false` to identify the release as a full release. Default `false`
### Outputs
For more information on these outputs, see the [API Documentation](https://developer.github.com/v3/repos/releases/#response-4) for an example of what these outputs look like
- `id`: The release ID
- `html_url`: The URL users can navigate to in order to view the release. i.e. `https://github.com/octocat/Hello-World/releases/v1.0.0`
- `upload_url`: The URL for uploading assets to the release, which could be used by GitHub Actions for additional uses, for example the [`@actions/upload-release-asset`](https://www.github.com/actions/upload-release-asset) GitHub Action
### Example workflow - create a release
On every `push` to a tag matching the pattern `v*`, [create a release](https://developer.github.com/v3/repos/releases/#create-a-release):
```yaml
on:
push:
# Sequence of patterns matched against refs/tags
tags:
- 'v*' # Push events to matching v*, i.e. v1.0, v20.15.10
name: Create Release
jobs:
build:
name: Create Release
runs-on: ubuntu-latest
steps:
- name: Checkout code
uses: actions/checkout@master
- name: Create Release
id: create_release
uses: actions/create-release@master
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
with:
tag_name: ${{ github.ref }}
release_name: Release ${{ github.ref }}
body: |
Changes in this Release
- First Change
- Second Change
draft: false
prerelease: false
```
This will create a [Release](https://help.github.com/en/articles/creating-releases), as well as a [`release` event](https://developer.github.com/v3/activity/events/types/#releaseevent), which could be handled by a third party service, or by GitHub Actions for additional uses, for example the [`@actions/upload-release-asset](https://www.github.com/actions/upload-release-asset) GitHub Action.
