Semantic version generator

Project created overnight, to prove that management of semantic versioning is NOT painful and do not require arguments and debates within the team. Simple, clean and only thing the project team should need to agree to are the keywords.

How does it work

• Binary clones the github repository
• Iterates through the list of commits looking for the keywords specified in config file for additional bumps of versions
• Returns the semantic version which can be included in the release

Additional features

• With flag -e or config force.existing: true the existing tags in versioning will be respected, helping you to avoid the version conflicts.
• With config force.commit: deadbeef where deadbeef is the commit hash - calculations will start from the specified commit.

Important changes

• From version 1.4.2+ as pointed out in issue #12 commits from merge will not be included in the calculations and commits themselves will bump the version on first match ( starting checks from patch upwards ).

Usage

Authentication

If you intend to use this project with remote repositories ( regardless of them being private or public ) you need to authenticate with your repository. To do so you can utilise the following environment variables ( they are NOT github specific, for other providers you can use the password )

export GITHUB_USERNAME=lukaszraczylo
export GITHUB_TOKEN=yourPersonalApiToken

As a binary

You can download latest versions of the binaries from the release page.

Supported OS and architectures: Darwin ARM64/AMD64, Linux ARM64/AMD64, Windows AMD64

bash$ ./semver-gen generate -r https://github.com/nextapps-de/winbox
SEMVER 9.0.10
bash$ ./semver-gen generate -l
SEMVER 5.1.1

Local repository flag -l will always take precedence over remote repository URL

Usage:
  semver-gen generate [flags]
  semver-gen [command]

Available Commands:
  generate    Generates semantic version
  help        Help about any command

Flags:
  -c, --config string       Path to config file (default "semver.yaml")
  -d, --debug               Enable debug mode
  -e, --existing            Respect existing tags
  -h, --help                help for semver-gen
  -l, --local               Use local repository
  -r, --repository string   Remote repository URL. (default "https://github.com/lukaszraczylo/simple-gql-client")
  -s, --strict              Strict matching
  -u, --update              Update binary with latest
  -v, --version             Display version

As a github action

jobs:
  prepare:
    name: Preparing build context
    runs-on: ubuntu-latest
    outputs:
      RELEASE_VERSION: ${{ steps.semver.outputs.semantic_version }}
    steps:
      - name: Checkout repo
        uses: actions/checkout@v2
        with:
          fetch-depth: '0'
      - name: Semver run
        id: semver
        uses: lukaszraczylo/semver-generator@PLACE_LATEST_TAG_HERE
        # you can also use v1 tag which _should_ automatically upgrade to latest
        # uses: lukaszraczylo/semver-generator@v1
        with:
          config_file: semver.yaml
          # either...
          repository_local: true
          # or...
          repository_url: https://github.com/lukaszraczylo/simple-gql-client
          # when using remote repository, especially with private one:
          github_username: lukaszraczylo
          github_token: MySupeRSecr3tPa$$w0rd
      - name: Semver check
        run: |
          echo "Semantic version detected: ${{ steps.semver.outputs.semantic_version }}"

As a docker container

docker pull ghcr.io/lukaszraczylo/semver-generator:latest

Docker supported architectures: Linux/arm64, Linux/amd64

Calculations example [standard]

- 0.0.1 - PATCH - starting commit
- 0.0.2 - PATCH - another commit
- 0.0.4 - PATCH - another commit with word 'Update' => DOUBLE increment PATCH
- 0.1.0 - MINOR - after commit with word 'Change' => increment MINOR, reset PATCH
- 0.1.1 - PATCH - additional commit
- 1.0.1 - MAJOR - commit with word 'BREAKING' = > INCREMENT MAJOR, reset MINOR
- 1.0.2 - PATCH - another commit

Calculations example [strict matching]

- 0.0.1 - PATCH - starting commit
- 0.0.1 - PATCH - another commit
- 0.0.1 - PATCH - another commit with word 'Update' => SINGLE increment PATCH
- 0.1.0 - MINOR - after commit with word 'Change' => increment MINOR, reset PATCH
- 0.1.0 - PATCH - additional commit
- 1.0.0 - MAJOR - commit with word 'BREAKING' = > INCREMENT MAJOR, reset MINOR
- 1.0.0 - PATCH - another commit

Release candidates

The semver-gen supports release candidates generation as well. Add following configuration ( and change the trigger keywords to anything what suits you ) to generate the appropriate release in format 1.3.37-rc.1 and counting up until next minor trigger will be detected.

  release:
    - release-candidate
    - add-rc

Example configuration

version: 1
force:
  major: 1
  minor: 0
  patch: 1
  commit: 69fbe2df696f40281b9104ff073d26186cde1024
wording:
  patch:
    - update
    - initial
  minor:
    - change
    - improve
  major:
    - breaking
    - the # For testing purposes
  release:
    - release-candidate
    - add-rc

• version: is not respected at the moment, introduced for potential backwards compatibility in future
• force: sets the "starting" version, you don't need to specify this section as the default is always 0
• force.commit: allows you to set commit hash from which the calculations should start
• wording: words the program should look for in the git commits to increment (patch|minor|major)

Good to know

• Word matching uses fuzzy search AND is case INSENSITIVE
• I do not recommend using common words ( like "the" from the example configuration )
