Detect and Tag New Version test-status

This action allows you to detect a new version of your repository based on some change in its contents between commits, creating a git tag if a new version is detected.

For example, in a JavaScript repo, you could detect that the version field in package.json had changed from "1.0.0" to "1.1.0" and therefore create a v1.1.0 tag from the current commit.

Usage

The configuration below would create a new version tag in your repository any time the contents of a current-version.txt file changed.

Note: since this action examines your git history to detect changes, you must set a fetch-depth of at least 2 with actions/checkout for that history to be present.

# ...
jobs:
  tag-new-versions:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
        with:
          fetch-depth: 2
      - uses: salsify/action-detect-and-tag-new-version@v2
        with:
          version-command: |
            cat current-version.txt

Inputs

All inputs are optional.

  • version-command: a shell command that will be executed at the current HEAD and the previous commit. This command's output to stdout will be considered the effective version of your repository at a given commit. If unspecified, this action will attempt to determine an appropriate command to run automatically, as described below.
  • create-tag: may be set to false to only detect version changes and not create a new tag when the version changes.
  • tag-template: a template for producing a tag name from the current version of your repository. Any instance of {VERSION} in the string will be replaced with the actual detected version. Defaults to v{VERSION}.
  • tag-annotation-template: a template for producing a tag annotation from the current version of your repository. As with tag-template, any instance of {VERSION} in the string will be replaced with the actual detected version. May be set to an empty string to produce a lightweight (i.e. annotation-less) tag. Defaults to Released version {VERSION}.

Outputs

  • previous-version: the detected previous version of this repository
  • current-version: the detected current version of this repository
  • tag: if a new tag is created, this output will contain its name

Version Determination

If no version-command input is provided, this action will attempt to do something sensible by default.

  • If it finds a package.json, it will consider the contents of the version field there to be the repository version.
  • If it finds single *.gemspec file, it will consider the version defined there to be the repository version.

The logic for this detection and the corresponding version commands used can be found in determine-version.ts.
