inputs:
  scheme:
    description: |
      Versioning scheme - semver, calver or conventional_commits (defaults to semver).

      `conventional_commits` Will parse the last commit message (e.g. the merge commit) to
      determine the increment type, and supports the following increment types by keyword:
      - patch (build, chore, ci, docs, fix, perf, refactor, revert, style, test)
      - minor (feat)
      - major (any of the above keywords followed by a '!' character, or 'BREAKING CHANGE:' in commit body)
    required: false
    default: 'semver'
  pep440:
    description: 'PEP440 compatibility mode - shifts the pre-release version information into build metadata instead'
    required: false
    default: false
  increment:
    description: |
      Field to increment - major, minor, or, patch (defaults to patch)

      If using the `conventional_commits` scheme, this is the default increment if the parsing of the merge commit fails to
      find conventional commits information

      Not applicable to `calver` scheme
    required: false
    default: 'patch'
  release_branch:
    description: 'Specify a non-default branch to use for the release tag (the one without -pre)'
    required: false
    type: string
  use_api:
    description: 'Use the GitHub API to discover current tags, which avoids the need for a git checkout, but requires `curl` and `jq`'
    required: false
    default: false
  tag_prefix:
    description: |
      Field to prefix the tag with a string (defaults to empty string). This is useful for projects that use a prefix in their tags. E.g. if set to `@org/product` the action will return `@org/product/1.2.3` as version.
    required: false
    default: false
