git-tag

An action that can retrieve the current git version tag and optionally increment or push the new version to GitHub. The action sets the TAG environment variable for subsequent steps and it adds the tag as an output. If no tags are found for the repo, it defaults to v1.0.0. If this will be used multiple times in one job, use the TAG output rather than the environment variable. This action expects the git tag to be in the format .. and the output may not be as expected if it is in a different format.

Inputs

Parameter	Is Required	Default	Description
github-token	false	N/A	Used to create the new tag. Value is generally: secrets.GITHUB_TOKEN. Required when pushing a new tag.
increment-major	false	false	Flag to indicate whether to increment the major version. When true, the major is incremented and minor/patch are set to 0.
increment-minor	false	false	Flag to indicate whether to increment the minor version. When true, the minor is incremented and patch is set to 0.
increment-patch	false	false	Flag to indicate whether to increment the patch version.
push-new-tag-to-repo	false	false	Flag to indicate whether to push a new incremented tag to GitHub. If none of the major/minor/patch flags are set, this will not happen.
separator	false	.	The separator the version tag uses.
prefix	false	N/A	The prefix of the git tags if it has one. Commonly used when tags contain the project in addition to the major.minor.patch.
includePrefixInOutput	false	false	Flag indicating whether the prefix should be included in the environment variable or output if one is present.

Outputs

Output	Description
TAG	If any of the increment tags are set, it returns the incremented tag otherwise it returns the latest tag for the repository.

Usage Examples

Getting the version and using the ENV variable in later steps:

jobs:
  get-the-version-for-pack:
    runs-on: ubuntu-20.04
    steps:
      - uses: actions/checkout@v2

      - name: Get the current version
        uses: im-open/[email protected]
        
      - name: donet pack with current git version
        run: dotnet pack -p:PackageVersion=${{ env.TAG }}
        

Incrementing the version for multiple repositories, pushing the new tag for one and using the outputs in later steps:

jobs:
  get-the-version-for-pack:
    runs-on: ubuntu-20.04
    steps:
      - uses: actions/checkout@v2

      - name: Increment the current db version and push it
        id: db-version
        uses: im-open/[email protected]
        with:
          increment-minor: true
          separator: '-' 
          prefix: 'DB-' # This project uses git tags like DB-1-0-0 
          includePrefixInOutput: 'false'
          push-new-tag-to-repo: 'true'
          github-token: ${{ secrets.GITHUB_TOKEN }}
      
      - name: Get the current app version
        id: app-version
        uses: im-open/[email protected]
        with:
          increment-patch: true
          prefix: 'BFF-' # This project uses git tags like BFF-1.1.0 
          includePrefixInOutput: 'false'
      
      - name: pack db with current git version
        working-directory: ./src/db
        run: dotnet pack -p:PackageVersion=${{ steps.db-version.outputs.TAG }}
      
      - name: build app with current git version
        working-directory: ./src/app
        run: dotnet build -p:PackageVersion=${{ steps.app-version.outputs.TAG }}
        

Recompiling

If changes are made to the action's code in this repository, or its dependencies, you will need to re-compile the action.

# Installs dependencies and bundles the code
npm run build

# Bundle the code (if dependencies are already installed)
npm run bundle

These commands utilize esbuild to bundle the action and its dependencies into a single file located in the dist folder.
