git-version

Note

This repo is a fork of codacy/git-version with the following features and fixes, all of which have pull-requests back to upstream:

features:

fixes:

These feature and fixes are needed so we can replace the unverified action paulhatch/semantic-version see https://toitutewhenua.atlassian.net/browse/ENABLE-4773

This repo needs to exist until the above PRs get merged.

To create new release in this fork, run the following scripts:

install build tool for Crystal language

curl -fsSL https://crystal-lang.org/install.sh | sudo bash

Test and build

make docker_build
docker run --entrypoint cat codacy/git-version:$(cat .version) /bin/git-version > bin/git-version

Commit and push change to master branch

Create release

gh release create <version> bin/git-version --generate-notes --target <commit-sha>

The goal of this tool is to have a simple versioning system that we can use to track the different releases. The tool prints the current version (e.g. to be used for tagging) depending on the git history and commit messages.

The versioning scheme is assumed to be Semver based.

Usage

# .github/workflows/version.yml
name: Git Version

on:
  push:
    branches:
      - master

jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Code
        uses: actions/checkout@v3
        with:
          ref: ${{ github.head_ref }}   # checkout the correct branch name
          fetch-depth: 0                # fetch the whole repo history

      - name: Git Version
        id: version
        uses: codacy/git-version@2.7.1
      
      - name: Use the version
        run: |
          echo ${{ steps.version.outputs.version }}
      - name: Use the previous version
        run: |
          echo ${{ steps.version.outputs.previous-version }}

Mono-Repo

You can use git-version to version different modules in a mono-repo structure. This can be achieved by using different prefixes and log-path filters for different modules.

Assuming the following directory structure, we can use git-version to generate version with prefix module1-x.x.x for changes in the module1/ directory and module2-x.x.x for changes in the module2/ directory.

.
├── Dockerfile
├── Makefile
├── README.md
├── module1
│   ├── Dockerfile
│   └── src/
└── module2
    ├── Dockerfile
    └── src/

With github actions you can create different workflows that are triggered when changes happen on different directories.

# .github/workflows/module1.yml
name: Version Module 1

on:
  pull_request:
    paths:
      - .github/workflows/module1.yml
      - module1/**
  push:
    paths:
      - .github/workflows/module1.yml
      - module1/**
    branches:
      - master

jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Code
        uses: actions/checkout@v3
        with:
          ref: ${{ github.head_ref }}   # checkout the correct branch name
          fetch-depth: 0                # fetch the whole repo history

      - name: Git Version
        uses: codacy/git-version@2.5.4
        with:
          prefix: module1-
          log-path: module1/

# .github/workflows/module2.yml
name: Version Module 2

on:
  pull_request:
    paths:
      - .github/workflows/module2.yml
      - module2/**
  push:
    paths:
      - .github/workflows/module2.yml
      - module2/**
    branches:
      - master

jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Code
        uses: actions/checkout@v3
        with:
          ref: ${{ github.head_ref }}   # checkout the correct branch name
          fetch-depth: 0                # fetch the whole repo history

      - name: Git Version
        uses: codacy/git-version@2.5.4
        with:
          prefix: module2-
          log-path: module2/

Versioning Model

Creates a version with the format MAJOR.MINOR.PATCH

To use this you need to be in the working dir of a git project:

$ ./git-version
1.0.0

Versions are incremented since the last tag. The patch version is incremented by default, unless there is at least one commit since the last tag, containing a minor or major identifier (defaults to feature: or breaking:) in the message.

On branches other than the master/main and development branch (default to master and dev) the version is a variation of the latest common tag with the master/main branch, and has the following format:

{MAJOR}.{MINOR}.{PATCH}-{sanitized-branch-name}.{commits-distance}.{hash}

On the development branch the format is the following:

{MAJOR}.{MINOR}.{PATCH}-SNAPSHOT.{hash}

Example:

---A---B---C <= Master (tag: 1.0.1)        L <= Master (git-version: 1.0.2)
            \                             /
             D---E---F---G---H---I---J---K <= Foo (git-version: 1.0.2-foo.8.5e30d83)

Example2 (with dev branch):

---A---B---C <= Master (tag: 1.0.1)        L <= Master (git-version: 1.0.2)
            \                             / <= Fast-forward merges to master (same commit id)
             C                           L <= Dev (git-version: 1.0.2-SNAPSHOT.5e30d83)
              \                         /
               E---F---G---H---I---J---K <= Foo (new_version: 1.0.1-foo.7.5e30d83)

Example3 (with breaking message):

---A---B---C <= Master (tag: 1.0.1)        L <= Master (git-version: 2.0.0)
            \                             /
             D---E---F---G---H---I---J---K <= Foo (git-version: 2.0.0-foo.8.5e30d83)
                                         \\
                                         message: "breaking: removed api parameter"

Configuration

You can configure the action with various inputs, a list of which has been provided below:

major-identifier	The string used to identify a major release (wrap with '/' to match using a regular expression)	breaking:
prefix	The prefix used for the version name
log-paths	The paths used to calculate changes (comma-separated)

CircleCI

Use this image directly on CircleCI for simple steps

version: 2
jobs:
  build:
    machine: true
    working_directory: /app
    steps:
      - checkout
      - run:
          name: get new version
          command: |
            NEW_VERSION=$(docker run --rm -v $(pwd):/repo codacy/git-version)
            echo $NEW_VERSION

Build and Publish

The pipeline in circleci can deploy this for you when the code is pushed to the remote.

To compile locally you need to install crystal and possibly all required libraries

You can also run everything locally using the makefile.
