class RDoc::Options

RDoc::Options handles the parsing and storage of options

Saved `Options`¶ ↑

You can save some options like the markup format in the .rdoc_options file in your gem. The easiest way to do this is:

rdoc --markup tomdoc --write-options

Which will automatically create the file and fill it with the options you specified.

The following options will not be saved since they interfere with the user’s preferences or with the normal operation of RDoc:

--coverage-report
--dry-run
--encoding
--force-update
--format
--pipe
--quiet
--template
--verbose

Custom `Options`¶ ↑

Generators can hook into RDoc::Options to add generator-specific command line options.

When --format is encountered in ARGV, RDoc calls ::setup_options on the generator class to add extra options to the option parser. Options for custom generators must occur after --format. rdoc --help will list options for all installed generators.

Example:

class RDoc::Generator::Spellcheck
  RDoc::RDoc.add_generator self

  def self.setup_options rdoc_options
    op = rdoc_options.option_parser

    op.on('--spell-dictionary DICTIONARY',
          RDoc::Options::Path) do |dictionary|
      rdoc_options.spell_dictionary = dictionary
    end
  end
end

Of course, RDoc::Options does not respond to spell_dictionary by default so you will need to add it:

class RDoc::Options

  ##
  # The spell dictionary used by the spell-checking plugin.

  attr_accessor :spell_dictionary

end

Option Validators¶ ↑

OptionParser validators will validate and cast user input values. In addition to the validators that ship with OptionParser (String, Integer, Float, TrueClass, FalseClass, Array, Regexp, Date, Time, URI, etc.), RDoc::Options adds Path, PathArray and Template.

Constants

DEPRECATED: The deprecated options.
Directory: Option validator for OptionParser that matches a directory that exists on the filesystem.
Path: Option validator for OptionParser that matches a file or directory that exists on the filesystem.
PathArray: Option validator for OptionParser that matches a comma-separated list of files or directories that exist on the filesystem.
SPECIAL: RDoc options ignored (or handled specially) by –write-options
Template: Option validator for OptionParser that matches a template directory for an installed generator that lives in "rdoc/generator/template/#{template_name}"

load_options ()

Source

# File lib/rdoc/options.rb, line 1323
def self.load_options
  options_file = File.expand_path '.rdoc_options'
  return RDoc::Options.new unless File.exist? options_file

  RDoc.load_yaml

  begin
    options = YAML.safe_load File.read('.rdoc_options'), permitted_classes: [RDoc::Options, Symbol]
  rescue Psych::SyntaxError
    raise RDoc::Error, "#{options_file} is not a valid rdoc options file"
  end

  return RDoc::Options.new unless options # Allow empty file.

  raise RDoc::Error, "#{options_file} is not a valid rdoc options file" unless
    RDoc::Options === options or Hash === options

  if Hash === options
    # Override the default values with the contents of YAML file.
    options = RDoc::Options.new options
  end

  options
end

Loads options from .rdoc_options if the file exists, otherwise creates a new RDoc::Options instance.

Public Instance Methods

check_files ()

Source

# File lib/rdoc/options.rb, line 493
def check_files
  @files.delete_if do |file|
    if File.exist? file then
      if File.readable? file then
        false
      else
        warn "file '#{file}' not readable"

        true
      end
    else
      warn "file '#{file}' not found"

      true
    end
  end
end

Check that the files on the command line exist

check_generator ()

Source

# File lib/rdoc/options.rb, line 514
def check_generator
  if @generator then
    raise OptionParser::InvalidOption,
      "generator already set to #{@generator_name}"
  end
end

Ensure only one generator is loaded

default_title= (string)

Source

# File lib/rdoc/options.rb, line 526
def default_title=(string)
  @title ||= string
end

Set the title, but only if not already set. Used to set the title from a source file, so that a title set from the command line will have the priority.

exclude ()

Source

# File lib/rdoc/options.rb, line 554
def exclude
  if @exclude.nil? or Regexp === @exclude then
    # done, #finish is being re-run
    @exclude
  elsif @exclude.empty? then
    nil
  else
    Regexp.new(@exclude.join("|"))
  end
end

Create a regexp for exclude

finish ()

Source

# File lib/rdoc/options.rb, line 570
def finish
  if @write_options then
    write_options
    exit
  end

  @op_dir ||= 'doc'

  root = @root.to_s
  if @rdoc_include.empty? || !@rdoc_include.include?(root)
    @rdoc_include << root
  end

  @exclude = self.exclude

  finish_page_dir

  check_files

  # If no template was specified, use the default template for the output
  # formatter

  unless @template then
    @template     = @generator_name
    @template_dir = template_dir_for @template
  end

  if @locale_name
    @locale = RDoc::I18n::Locale[@locale_name]
    @locale.load(@locale_dir)
  else
    @locale = nil
  end

  self
end

Completes any unfinished option setup business such as filtering for existent files, creating a regexp for exclude and setting a default template.

finish_page_dir ()

Source

# File lib/rdoc/options.rb, line 611
def finish_page_dir
  return unless @page_dir

  @files << @page_dir

  page_dir = Pathname(@page_dir)
  begin
    page_dir = page_dir.expand_path.relative_path_from @root
  rescue ArgumentError
    # On Windows, sometimes crosses different drive letters.
    page_dir = page_dir.expand_path
  end

  @page_dir = page_dir
end

Fixes the page_dir to be relative to the root_dir and adds the page_dir to the files list.

generator_descriptions ()

Source

# File lib/rdoc/options.rb, line 630
def generator_descriptions
  lengths = []

  generators = RDoc::RDoc::GENERATORS.map do |name, generator|
    lengths << name.length

    description = generator::DESCRIPTION if
      generator.const_defined? :DESCRIPTION

    [name, description]
  end

  longest = lengths.max

  generators.sort.map do |name, description|
    if description then
      "  %-*s - %s" % [longest, name, description]
    else
      "  #{name}"
    end
  end.join "\n"
end

Returns a properly-space list of generators and their descriptions.

parse (argv)

Source

# File lib/rdoc/options.rb, line 656
  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 = <<-EOF
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:

      EOF

      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|

Parses command line options.

quiet ()

Source

# File lib/rdoc/options.rb, line 1209
def quiet
  @verbosity.zero?
end

Don’t display progress as we process the files

quiet= (bool)

Source

# File lib/rdoc/options.rb, line 1216
def quiet= bool
  @verbosity = bool ? 0 : 1
end

Set quietness to bool

sanitize_path (path)

Source

# File lib/rdoc/options.rb, line 1223
def sanitize_path path
  require 'pathname'
  dot = Pathname.new('.').expand_path

  path.reject do |item|
    path = Pathname.new(item).expand_path
    is_reject = nil
    relative = nil
    begin

      is_reject = true
    else
      is_reject = relative.start_with? '..'
    end
    is_reject
  end
end

Removes directories from path that are outside the current directory

setup_generator (generator_name = @generator_name)

Source

# File lib/rdoc/options.rb, line 1250
def setup_generator generator_name = @generator_name
  @generator = @generators[generator_name]

  unless @generator then
    raise OptionParser::InvalidArgument,
          "Invalid output formatter #{generator_name}"

  @generator_options << @generator

  if @generator.respond_to? :setup_options then
    @option_parser ||= OptionParser.new
    @generator.setup_options self
  end
end

Set up an output generator for the named generator_name.

If the found generator responds to :setup_options it will be called with the options instance. This allows generators to add custom options or set default options.

template_dir_for (template)

Source

# File lib/rdoc/options.rb, line 1272
def template_dir_for template
  template_path = File.join 'rdoc', 'generator', 'template', template

  $LOAD_PATH.map do |path|
    File.join File.expand_path(path), template_path
  end.find do |dir|
    File.directory? dir
  end
end

Finds the template dir for template

visibility= (visibility)

Source

# File lib/rdoc/options.rb, line 1289
def visibility= visibility
  case visibility
  when :all
    @visibility = :private
  else
    @visibility = visibility
  end
end

Sets the minimum visibility of a documented method.

Accepts :public, :protected, :private, :nodoc, or :all.

When :all is passed, visibility is set to :private, similarly to RDOCOPT=“–all”, see visibility for more information.

warn (message)

Source

# File lib/rdoc/options.rb, line 1301
def warn message
  super message if @verbosity > 1
end

Displays a warning using Kernel#warn if we’re being verbose

Calls superclass method Kernel#warn

write_options ()

Source

# File lib/rdoc/options.rb, line 1309
def write_options
  RDoc.load_yaml

  File.open '.rdoc_options', 'w' do |io|
    io.set_encoding Encoding::UTF_8

    io.print to_yaml
  end
end

Writes the YAML file .rdoc_options to the current directory containing the parsed options.
