# frozen_string_literal: true

module SyntaxSuggest
  # Searches code for a syntax error
  #
  # There are three main phases in the algorithm:
  #
  # 1. Sanitize/format input source
  # 2. Search for invalid blocks
  # 3. Format invalid blocks into something meaninful
  #
  # This class handles the part.
  #
  # The bulk of the heavy lifting is done in:
  #
  #  - CodeFrontier (Holds information for generating blocks and determining if we can stop searching)
  #  - ParseBlocksFromLine (Creates blocks into the frontier)
  #  - BlockExpand (Expands existing blocks to search more code)
  #
  # ## Syntax error detection
  #
  # When the frontier holds the syntax error, we can stop searching
  #
  #   search = CodeSearch.new(<<~EOM)
  #     def dog
  #       def lol
  #     end
  #   EOM
  #
  #   search.call
  #
  #   search.invalid_blocks.map(&:to_s) # =>
  #   # => ["def lol\n"]
