# File lib/rdoc/options.rb, line 564 def parse argv ignore_invalid = true argv.insert(0, *ENV['RDOCOPT'].split) if ENV['RDOCOPT'] opts = OptionParser.new do |opt| @option_parser = opt opt.program_name = File.basename $0 opt.version = RDoc::VERSION opt.release = nil opt.summary_indent = ' ' * 4 opt.banner = Usage: #{opt.program_name} [options] [names...] Files are parsed, and the information they contain collected, before any output is produced. This allows cross references between all files to be resolved. If a name is a directory, it is traversed. If no names are specified, all Ruby files in the current directory (and subdirectories) are processed. How RDoc generates output depends on the output formatter being used, and on the options you give. Options can be specified via the RDOCOPT environment variable, which functions similar to the RUBYOPT environment variable for ruby. $ export RDOCOPT="--show-hash" will make rdoc show hashes in method links by default. Command-line options always will override those in RDOCOPT. Available formatters:#{generator_descriptions} RDoc understands the following file formats: parsers = Hash.new { |h,parser| h[parser] = [] } RDoc::Parser.parsers.each do |regexp, parser| parsers[parser.name.sub('RDoc::Parser::', '')] << regexp.source end parsers.sort.each do |parser, regexp| opt.banner << " - #{parser}: #{regexp.join ', '}\n" end opt.banner << " - TomDoc: Only in ruby files\n" opt.banner << "\n The following options are deprecated:\n\n" name_length = DEPRECATED.keys.sort_by { |k| k.length }.last.length DEPRECATED.sort_by { |k,| k }.each do |name, reason| opt.banner << " %*1$2$s %3$s\n" % [-name_length, name, reason] end opt.accept Template do |template| template_dir = template_dir_for template unless template_dir then $stderr.puts "could not find template #{template}" nil else [template, template_dir] end end opt.accept Directory do |directory| directory = File.expand_path directory raise OptionParser::InvalidArgument unless File.directory? directory directory end opt.accept Path do |path| path = File.expand_path path raise OptionParser::InvalidArgument unless File.exist? path path end opt.accept PathArray do |paths,| paths = if paths then paths.split(',').map { |d| d unless d.empty? } end paths.map do |path| path = File.expand_path path raise OptionParser::InvalidArgument unless File.exist? path path end end opt.separator nil opt.separator "Parsing options:" opt.separator nil if Object.const_defined? :Encoding then opt.on("--encoding=ENCODING", "-e", Encoding.list.map { |e| e.name }, "Specifies the output encoding.
