GitHub Tag Action

A GitHub Action to automatically bump and tag master, on merge, with the latest SemVer formatted version. Works on any platform.

Usage

…

Inputs

• github_token (required) - Required for permission to tag the repo. Usually ${{ secrets.GITHUB_TOKEN }}.
• commit_sha (optional) - The commit SHA value to add the tag. If specified, it uses this value instead GITHUB_SHA. It could be useful when a previous step merged a branch into github.ref.

Fetch all tags

• fetch_all_tags (optional) - By default, this action fetch the last 100 tags from Github. Sometimes, this is not enough and using this action will fetch all tags recursively (default: false).

Filter branches

• release_branches (optional) - Comma separated list of branches (JavaScript regular expression accepted) that will generate the release tags. Other branches and pull-requests generate versions postfixed with the commit hash and do not generate any repository tag. Examples: master or .* or release.*,hotfix.*,master... (default: master,main).
• pre_release_branches (optional) - Comma separated list of branches (JavaScript regular expression accepted) that will generate the pre-release tags.

Customize the tag

• default_bump (optional) - Which type of bump to use when none is explicitly provided when commiting to a release branch (default: patch). You can also set false to avoid generating a new tag when none is explicitly provided. Can be patch, minor or major.
• default_prerelease_bump (optional) - Which type of bump to use when none is explicitly provided when commiting to a prerelease branch (default: prerelease). You can also set false to avoid generating a new tag when none is explicitly provided. Can be prerelease, prepatch, preminor or premajor.
• custom_tag (optional) - Custom tag name. If specified, it overrides bump settings.
• create_annotated_tag (optional) - Boolean to create an annotated rather than a lightweight one (default: false).
• tag_prefix (optional) - A prefix to the tag name (default: v).
• append_to_pre_release_tag (optional) - A suffix to the pre-release tag name (default: ``).

Customize the conventional commit messages & titles of changelog sections

• custom_release_rules (optional) - Comma separated list of release rules.

  Format: :: where `` is optional and will default to Angular's conventions.

  Examples:

  1. hotfix:patch,pre-feat:preminor,
  2. bug:patch:Bug Fixes,chore:patch:Chores

Debugging

• dry_run (optional) - Do not perform tagging, just calculate next version and changelog, then exit

Outputs

• new_tag - The value of the newly calculated tag. Note that if there hasn't been any new commit, this will be undefined.
• new_version - The value of the newly created tag without the prefix. Note that if there hasn't been any new commit, this will be undefined.
• previous_tag - The value of the previous tag (or v0.0.0 if none). Note that if custom_tag is set, this will be undefined.
• previous_version - The value of the previous tag (or 0.0.0 if none) without the prefix. Note that if custom_tag is set, this will be undefined.
• release_type - The computed release type (major, minor, patch or custom - can be prefixed with pre).
• changelog - The conventional changelog since the previous tag.

Note: This action creates a lightweight tag by default.

Bumping

The action will parse the new commits since the last tag using the semantic-release conventions.

semantic-release uses the commit messages to determine the type of changes in the codebase. Following formalized conventions for commit messages, semantic-release automatically determines the next semantic version number.

By default semantic-release uses Angular Commit Message Conventions.

Here is an example of the release type that will be done based on a commit messages:

Commit message Release type

fix(pencil): stop graphite breaking when too much pressure applied

Patch Release

feat(pencil): add 'graphiteWidth' option

Minor Release

perf(pencil): remove graphiteWidth option

BREAKING CHANGE: The graphiteWidth option has been removed.
The default graphite width of 10mm is always used for performance reasons.

Major Release

If no commit message contains any information, then default_bump will be used.
