#!/usr/bin/env ruby
# typed: true
# frozen_string_literal: true

# This script executes a full update run for a given repo (optionally for a
# specific dependency only), and shows the proposed changes to any dependency
# files without actually creating a pull request.
#
# It's used regularly by the Dependabot team to manually debug issues, so
# should always be up-to-date.
#
# Usage:
#   ruby bin/dry-run.rb [OPTIONS] PACKAGE_MANAGER GITHUB_REPO
#
# ! You'll need to have a GitHub access token (a personal access token is
# ! fine) available as the environment variable LOCAL_GITHUB_ACCESS_TOKEN.
#
# Example:
#   ruby bin/dry-run.rb go_modules zonedb/zonedb
#
# Package managers:
# - bundler
# - pip (includes pipenv)
# - npm_and_yarn
# - maven
# - gradle
# - cargo
# - hex
# - composer
# - nuget
# - go_modules
# - elm
# - submodules
# - docker
# - docker_compose
