Cartage::CLI.extend do
  desc "Work with the Manifest.txt file"
  long_desc <<~'DESC'
    Commands that manage the Cartage manifest (Manifest.txt) and ignore
    (.cartignore) files for a project.
  DESC
  command "manifest" do |manifest|
    manifest.desc "Check the Manifest.txt file against the current repository"
    manifest.long_desc <<~'DESC'
      Compares the current Cartage manifest against what would be calculated. If
      there is a difference, it will be displayed in unified ('diff -u') format and a
      non-zero exit status will be returned.
      
      The diff output can be suppressed by specifying -q on cartage:
      
          cartage -q manifest check
    DESC
    manifest.command "check" do |check|

          fail Cartage::CLI::QuietExit, $?.exitstatus
      end
    end

    manifest.desc "Install or update the .cartignore file"
    manifest.long_desc <<~'DESC'
      Creates, replaces, or updates the Cartage ignore file (.cartignore). Will not
      modify an existing .cartignore unless the --mode is overwrite or merge.
    DESC
    manifest.command "cartignore" do |cartignore|
      cartignore.desc "Overwrite or merge an existing .cartignore"
      cartignore.long_desc <<~'DESC'
        Sets the mode for updating the ignore file. When --mode overwrite, the ignore
        file will be replaced with the default ignore file contents. When --mode merge,
        the existing ignore file will be merged with the default ignore file contents.
