Next Version (GitHub Action)

A GitHub Action for determining the version for the next release based on branch name and existing releases. This Action expects, that you use Semantic Versioning for your project

Single Project Repository

If your repository hosts a single project, this Action expects, that you manage releases in release/vX.Y branches, and that GitHub Releases are tagged with vX.Y.Z. The Action fetches all existing Github Releases form the repository and finds the highest one for the branch it is executed on. Then it returns this version's patch number increased by one.

Multi Project Repository

If your repository hosts more than one project and these projects have individual lifecycles, this Action expects, that these projects are located in different folders on root level and that the releases are managed in release/folder/vX.Y branches, where folder matches the exact folder name of the project. The task then finds the latest matching GitHub Release with a folder-vX.Y.Z tag and increases that number.

Check the examples below for more details.

Usage

- uses: wemogy/[email protected]
  id: release-version
  with:
    token: ${{ secrets.GITHUB_TOKEN }}
    projects: 'Single'

- run: echo ${{ steps.release-version.outputs.next-version }}

Inputs

Input	Description
token	Required A GitHub Access Token
repo	The repository name (Default: current repository)
username	The GitHub username (Default: current repository owner)
branch	The release branch to check (Default: current branch)
projects	The amount of projects in this repo (Single or Multi) (Default: Single)
prefix	A prefix to all versions and release branches (Default: v)

Outputs

Output	Description
next-version	The next semantic version for the next release without prefix
next-version-name	The next semantic version for the next release with prefix
folder	The name of the folder for the branch

Examples

Single Project Repository

Given your repo has GitHub Releases with the following tags:

• v1.0.0
• v1.1.0
• v1.1.1
• v1.2.0

and the following branches:

• main
• release/v1.0
• release/v1.1
• release/v1.2

then a task with the configuration below generates the following outputs:

- uses: wemogy/[email protected]
  id: release-version
  with:
    token: ${{ secrets.GITHUB_TOKEN }}
    branch: 'release/v1.1'

- run: echo ${{ steps.release-version.outputs.next-version }} # Output: 1.1.2
- run: echo ${{ steps.release-version.outputs.next-version-name }} # Output: v1.1.2
- run: echo ${{ steps.release-version.outputs.folder }} # Output: <empty>

In this example, the Action identifies version 1.1.1 as the hightest one for the release/v1.1 tag. So the next patch version would be 1.1.2 and get the tag v1.1.2.

Multi Project Repository

Given your repo contains multiple projects in the following folders:

• /project-a
• /project-b

and GitHub Releases with the following tags:

• project-a-v1.0.0
• project-a-v1.1.0
• project-b-v1.0.0

and the following branches:

• main
• release/project-a/v1.0
• release/project-a/v1.1
• release/project-b/v1.0

then a task with the configuration below generates the following outputs:

- uses: wemogy/[email protected]
  id: release-version
  with:
    token: ${{ secrets.GITHUB_TOKEN }}
    branch: 'release/project-a/v1.1'
    projects: 'Multi'

- run: echo ${{ steps.release-version.outputs.next-version }} # Output: 1.1.1
- run: echo ${{ steps.release-version.outputs.next-version-name }} # Output: v1.1.1
- run: echo ${{ steps.release-version.outputs.folder }} # Output: project-a

In this example, the Action identifies version 1.1.0 as the hightest one for the release/project-a/1.1 tag. So the next patch version would be 1.1.1 and get the tag project-a-v1.1.2.

Prefix

By default, this Action prepends a v to the version name and tags and expects that the release branches are named release/vX.Y or release/project-a/vX.Y with a v before the version number. You can adjust this version prefix with the prefix input.

- uses: wemogy/[email protected]
  id: release-version
  with:
    token: ${{ secrets.GITHUB_TOKEN }}
    branch: 'release/1.1'
    projects: 'Single'
    prefix: '' # <- omit the prefix

- run: echo ${{ steps.release-version.outputs.next-version }} # Output: 1.1.1
- run: echo ${{ steps.release-version.outputs.next-version-name }} # Output: 1.1.1
