Semver Release Github Action

Fork information

Based on https://github.com/K-Phoen/semver-release-action

Additions:

default_increment - default increment bump when label is not found, default "skip"
tag_format - allows to use prefix/suffix in the format to manage separate components in monorepo

Description

Automatically create SemVer compliant releases based on PR labels.

Assuming that a PR is tagged with a "semver-compliant" label (patch, minor or major), then this action can create a tag and a GitHub release when it is merged.

Note: to determine the base tag for the increment, this action will try to find the most recent tag complying to SemVer. No additional setup is required.

Inputs

`release_branch`

Required Branch to tag. Default "master".

`release_strategy`

Required Release strategy. Default "release" (release: creates a GitHub release ; tag: creates a lightweight tag ; none: computes the next SemVer version but does not create a release or tag).

`default_increment`

Required Default increment (skip/patch/minor/major). Default "skip".

`tag_format`

Optional Format used to create tags. Default "v%major%.%minor%.%patch%".

`tag`

Optional Tag to use. If left undefined, it will be computed using the tags already present in the repository.

Outputs

`tag`

The newly created tag.
