Class: RDoc::Options

Relationships & Source Files
Inherits:	Object
Defined in:	lib/rdoc/options.rb

Overview

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 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, 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.), Options adds Path, PathArray and Template.

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:

RDoc understands the following file formats:

    EOF

    parsers = Hash.new { |h,parser| h[parser] = [] }
