The scan method is then called to return an appropriately parsed TopLevel code object. - !ruby/struct:SM::Flow::P body: The ParseFactory is used to redirect to the correct parser given a filename extension. This magic works because individual parsers have to register themselves with us as they are loaded in. The do this using the following incantation - !ruby/struct:SM::Flow::VERB body: " require "rdoc/parsers/parsefactory"\n\n module RDoc\n\n class XyzParser\n extend ParseFactory <<<<\n parse_files_matching /\\.xyz$/ <<<<\n\n def initialize(file_name, body, options)\n ...\n end\n\n def scan\n ...\n end\n end\n end\n" - !ruby/struct:SM::Flow::P body: Just to make life interesting, if we suspect a plain text file, we also look for a shebang line just in case it's a potential shell script constants: - !ruby/object:RI::Constant comment: name: Parsers value: Struct.new(:regexp, :parser) full_name: RDoc::ParserFactory includes: [] instance_methods: - !ruby/object:RI::MethodSummary name: parse_files_matching name: ParserFactory superclass:
