inputs:
  github_token:
    description: A Github token for the repo, usually `{{ github.token }}`.
    required: true
  tag:
    description: >
      A manual tag to compute the next version of. If not specified, it will fetch the most recent
      tag for the repo.
    required: false
  branch:
    description: >
      The branch to find compute the tag for. This requires iteration of all tags for the repo and
      the commits for the branch to find a tag for a commit on the branch. For large repositories
      this can be very slow. It is highly recommended that `github_token` be supplied to prevent
      rate limit errors when searching.
    required: false
  tag_fetch_depth:
    description: The number of most recent tags to fetch when attempting to find a match on the branch.
    required: false
    default: 10
  version_scheme:
    description: The versioning scheme to use. Currently only supports `continuous` or `semantic`.
    required: false
    default: semantic
  version_type:
    description: Is this a major, minor, patch, or prerelease bump?
    required: false
    default: prerelease
  prerelease_suffix:
    description: What to annotate a prerelease version tag with.
    required: false
    default: 'beta'
  tag_prefix:
    description: >
      Prefix for tags. When set, only tags starting with this prefix are considered
      for version computation, and the prefix is applied to the computed next tag.
      When unset, existing behavior is preserved (auto-detects 'v' prefix).
    required: false

outputs:
  next_tag:
    description: The computed next tag to be created
  previous_tag:
    description: The tag that was used to compute next_tag
