# = RDOC - Ruby Documentation System
#
# This package contains RDoc and RDoc::Markup. RDoc is an application that
# produces documentation for one or more Ruby source files. We work similarly
# to JavaDoc, parsing the source, and extracting the definition for classes,
# modules, and methods (along with includes and requires). We associate with
# these optional documentation contained in the immediately preceding comment
# block, and then render the result using a pluggable output formatter.
# RDoc::Markup is a library that converts plain text into various output
# formats. The markup library is used to interpret the comment blocks that
# RDoc uses to document methods, classes, and so on.
#
# == Roadmap
#
# * If you want to use RDoc to create documentation for your Ruby source files,
# read on.
# * If you want to include extensions written in C, see RDoc::C_Parser
# * For information on the various markups available in comment blocks, see
# RDoc::Markup.
# * If you want to drive RDoc programatically, see RDoc::RDoc.
# * If you want to use the library to format text blocks into HTML, have a look
# at RDoc::Markup.
# * If you want to try writing your own HTML output template, see
# RDoc::Generator::HTML
#
# == Summary
#
# Once installed, you can create documentation using the 'rdoc' command
# (the command is 'rdoc.bat' under Windows)
#
# % rdoc [options] [names...]
#
# Type "rdoc --help" for an up-to-date option summary.
#
# A typical use might be to generate documentation for a package of Ruby
# source (such as rdoc itself).
#
# % rdoc
#
# This command generates documentation for all the Ruby and C source
# files in and below the current directory. These will be stored in a
# documentation tree starting in the subdirectory 'doc'.
#
# You can make this slightly more useful for your readers by having the
# index page contain the documentation for the primary file. In our
# case, we could type
#
# % rdoc --main rdoc.rb
#
# You'll find information on the various formatting tricks you can use
# in comment blocks in the documentation this generates.
#
# RDoc uses file extensions to determine how to process each file. File names
# ending +.rb+ and <tt>.rbw</tt> are assumed to be Ruby source. Files
# ending +.c+ are parsed as C files. All other files are assumed to
# contain just Markup-style markup (with or without leading '#' comment
# markers). If directory names are passed to RDoc, they are scanned
# recursively for C and Ruby source files only.
#
# = Markup
#
# For information on how to make lists, hyperlinks, etc. with RDoc, see
# RDoc::Markup.
#
# Comment blocks can be written fairly naturally, either using '#' on
# successive lines of the comment, or by including the comment in
# an =begin/=end block. If you use the latter form, the =begin line must be
# flagged with an RDoc tag:
#
# =begin rdoc
# Documentation to be processed by RDoc.
#
# ...
# =end
#
# RDoc stops processing comments if it finds a comment line containing
# a <tt>--</tt>. This can be used to separate external from internal
# comments, or to stop a comment being associated with a method, class, or
# module. Commenting can be turned back on with a line that starts with a
# <tt>++</tt>.
#
# ##
# # Extract the age and calculate the date-of-birth.
# #--
# # FIXME: fails if the birthday falls on February 29th
# #++
# # The DOB is returned as a Time object.
#
# def get_dob(person)
# # ...
# end
#
# Names of classes, source files, and any method names containing an
# underscore or preceded by a hash character are automatically hyperlinked
# from comment text to their description.
#
# Method parameter lists are extracted and displayed with the method
# description. If a method calls +yield+, then the parameters passed to yield
# will also be displayed:
#
# def fred
# ...
# yield line, address
#
# This will get documented as:
#
# fred() { |line, address| ... }
#
# You can override this using a comment containing ':yields: ...' immediately
# after the method definition
#
# def fred # :yields: index, position
# # ...
#
# yield line, address
#
# which will get documented as
#
# fred() { |index, position| ... }
#
# +:yields:+ is an example of a documentation directive. These appear
# immediately after the start of the document element they are modifying.
#
# == Directives
#
# [+:nodoc:+ / +:nodoc:+ all]
# Don't include this element in the documentation. For classes
# and modules, the methods, aliases, constants, and attributes
# directly within the affected class or module will also be
# omitted. By default, though, modules and classes within that
# class of module _will_ be documented. This is turned off by
# adding the +all+ modifier.
#
# module MyModule # :nodoc:
# class Input
# end
# end
#
# module OtherModule # :nodoc: all
# class Output
# end
# end
#
# In the above code, only class +MyModule::Input+ will be documented.
# :nodoc: is global across all files the class or module appears in, so use
# :stopdoc:/:startdoc: to only omit documentation for a particular set of
# methods, etc.
#
# [+:doc:+]
# Force a method or attribute to be documented even if it wouldn't otherwise
# be. Useful if, for example, you want to include documentation of a
# particular private method.
#
# [+:notnew:+]
# Only applicable to the +initialize+ instance method. Normally RDoc
# assumes that the documentation and parameters for #initialize are
# actually for the ::new method, and so fakes out a ::new for the class.
# The :notnew: modifier stops this. Remember that #initialize is protected,
# so you won't see the documentation unless you use the -a command line
# option.
#
# Comment blocks can contain other directives:
#
# [<tt>:section: title</tt>]
# Starts a new section in the output. The title following +:section:+ is
# used as the section heading, and the remainder of the comment containing
# the section is used as introductory text. Subsequent methods, aliases,
# attributes, and classes will be documented in this section. A :section:
# comment block may have one or more lines before the :section: directive.
# These will be removed, and any identical lines at the end of the block are
# also removed. This allows you to add visual cues such as:
#
# # ----------------------------------------
# # :section: My Section
# # This is the section that I wrote.
# # See it glisten in the noon-day sun.
# # ----------------------------------------
#
# [+:call-seq:+]
# Lines up to the next blank line in the comment are treated as the method's
# calling sequence, overriding the default parsing of method parameters and
# yield arguments.
#
# [+:include:+ _filename_]
# \Include the contents of the named file at this point. The file will be
# searched for in the directories listed by the +--include+ option, or in
# the current directory by default. The contents of the file will be
# shifted to have the same indentation as the ':' at the start of the
# :include: directive.
#
# [+:title:+ _text_]
# Sets the title for the document. Equivalent to the <tt>--title</tt>
# command line parameter. (The command line parameter overrides any :title:
# directive in the source).
#
# [+:enddoc:+]
# Document nothing further at the current level.
#
# [+:main:+ _name_]
# Equivalent to the <tt>--main</tt> command line parameter.
#
# [+:stopdoc:+ / +:startdoc:+]
# Stop and start adding new documentation elements to the current container.
# For example, if a class has a number of constants that you don't want to
# document, put a +:stopdoc:+ before the first, and a +:startdoc:+ after the
# last. If you don't specifiy a +:startdoc:+ by the end of the container,
# disables documentation for the entire class or module.
