allegro-actions/next-version

This action calculates next tag based on git history.

Supports semver tags and custom formats.

Outputs

current_tag - latest found version tag next_tag - computed next tag next_version - computed next version

Basic usage:

- name: get next version
  id: 'bump'
  uses: allegro-actions/next-version@v1

- name: Push new tag on master
  if: github.ref == 'refs/heads/master'
  uses: allegro-actions/create-tag@v1
  with:
    tag: ${{ steps.bump.outputs.next_tag }}
    current-tag: ${{ steps.bump.outputs.current_tag }}

Will output v1.0.1 (assuming v1.0.0 tag exists)

Configuration

prefix

You can change prefix to handle my-app-1.0.0 tag

- name: get next tag
  id: 'bump'
  uses: allegro-actions/next-version@v1
  with:
    prefix: 'my-app-'

Will output my-app-1.0.1 (assuming my-app-1.0.0 tag exists)

versioning

You can add versioning to create v1 tag

- name: get next tag
  id: 'bump'
  uses: allegro-actions/next-version@v1
  with:
    versioning: 'single-number'

Will output v2 (assuming v1 tag exists)

Will output v1 if no previous tag found.

force

You can also force next version.

- name: get next tag
  id: 'bump'
  uses: allegro-actions/next-version@v1
  with:
    force: '4.0.0'

Will always output v4.0.0

Use cases

Adding manual control

i.e. adding workflow input parameter to force next tag manually:

name: Release

on:
  workflow_dispatch:
    inputs:
      forceVersion:
        description: 'Force version'
        required: false
        default: ''
jobs:
  release:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
        with:
          fetch-depth: 0
      - name: get next tag
        id: 'bump'
        uses: allegro-actions/next-version@v1
        with:
          force: ${{ github.event.inputs.forceVersion }}
