class RDoc::Context

A Context is something that can hold modules, classes, methods, attributes, aliases, requires, and includes. Classes, modules, and files are all Contexts.

Constants

TYPES: Types of methods

Attributes

aliases[R]

Class/module aliases

attributes[R]

All attr* methods

block_params[RW]

Block params to be used in the next MethodAttr parsed under this context

constants[R]

Constants defined

constants_hash[R]

Hash of registered constants.

current_line_visibility[W]

Current visibility of this line

current_section[W]

Sets the current documentation section of documentation

extends[R]

Modules this context is extended with

external_aliases[R]

Aliases that could not be resolved.

in_files[R]

Files this context is found in

includes[R]

Modules this context includes

method_list[R]

Methods defined in this context

methods_hash[R]

Hash of registered methods. Attributes are also registered here, twice if they are RW.

name[R]

Name of this class excluding namespace. See also full_name

params[RW]

Params to be used in the next MethodAttr parsed under this context

requires[R]

Files this context requires

temporary_section[RW]

Use this section for the next method, attribute or constant added.

unmatched_alias_lists[RW]

Hash old_name => [aliases], for aliases that haven’t (yet) been resolved to a method/attribute. (Not to be confused with the aliases of the context.)

visibility[RW]

Current visibility of this context

Public Class Methods

new() click to toggle source

Creates an unnamed empty context with public current visibility

Calls superclass method RDoc::CodeObject::new

# File lib/rdoc/context.rb, line 125
def initialize
  super

  @in_files = []

  @name    ||= "unknown"
  @parent  = nil
  @visibility = :public

  @current_section = Section.new self, nil, nil
  @sections = { nil => @current_section }
  @temporary_section = nil

  @classes = {}
  @modules = {}

  initialize_methods_etc
end

Public Instance Methods

<=>(other) click to toggle source

Contexts are sorted by full_name

# File lib/rdoc/context.rb, line 173
def <=>(other)
  return nil unless RDoc::CodeObject === other

  full_name <=> other.full_name
end

add(klass, name, comment) click to toggle source

Adds an item of type klass with the given name and comment to the context.

Currently only RDoc::Extend and RDoc::Include are supported.

# File lib/rdoc/context.rb, line 185
def add klass, name, comment
  if RDoc::Extend == klass then
    ext = RDoc::Extend.new name, comment
    add_extend ext
  elsif RDoc::Include == klass then
    incl = RDoc::Include.new name, comment
    add_include incl
  else
    raise NotImplementedError, "adding a #{klass} is not implemented"
  end
end

add_alias(an_alias) click to toggle source

Adds an_alias that is automatically resolved

# File lib/rdoc/context.rb, line 200
def add_alias an_alias
  return an_alias unless @document_self

  method_attr = find_method(an_alias.old_name, an_alias.singleton) ||
                find_attribute(an_alias.old_name, an_alias.singleton)

  if method_attr then
    method_attr.add_alias an_alias, self
  else
    add_to @external_aliases, an_alias
    unmatched_alias_list =
      @unmatched_alias_lists[an_alias.pretty_old_name] ||= []
    unmatched_alias_list.push an_alias
  end

  an_alias
end

add_attribute(attribute) click to toggle source

Adds attribute if not already there. If it is (as method(s) or attribute), updates the comment if it was empty.

The attribute is registered only if it defines a new method. For instance, attr_reader :foo will not be registered if method foo exists, but attr_accessor :foo will be registered if method foo exists, but foo= does not.

# File lib/rdoc/context.rb, line 227
def add_attribute attribute
  return attribute unless @document_self

  # mainly to check for redefinition of an attribute as a method
  # TODO find a policy for 'attr_reader :foo' + 'def foo=()'
  register = false

  key = nil

  if attribute.rw.index 'R' then
    key = attribute.pretty_name
    known = @methods_hash[key]

    if known then
      known.comment = attribute.comment if known.comment.empty?
    elsif registered = @methods_hash[attribute.pretty_name + '='] and
          RDoc::Attr === registered then
      registered.rw = 'RW'
    else
      @methods_hash[key] = attribute
      register = true
    end
  end

  if attribute.rw.index 'W' then
    key = attribute.pretty_name + '='
    known = @methods_hash[key]

    if known then
      known.comment = attribute.comment if known.comment.empty?
    elsif registered = @methods_hash[attribute.pretty_name] and
          RDoc::Attr === registered then
      registered.rw = 'RW'
    else
      @methods_hash[key] = attribute
      register = true
    end
  end

  if register then
    attribute.visibility = @visibility
    add_to @attributes, attribute
    resolve_aliases attribute
  end

  attribute
end

add_class(class_type, given_name, superclass = '::Object') click to toggle source

Adds a class named given_name with superclass.

Both given_name and superclass may contain ‘::’, and are interpreted relative to the self context. This allows handling correctly examples like these:

class RDoc::Gauntlet < Gauntlet
module Mod
  class Object   # implies < ::Object
  class SubObject < Object  # this is _not_ ::Object

Given class Container::Item RDoc assumes Container is a module unless it later sees class Container. add_class automatically upgrades given_name to a class in this case.

# File lib/rdoc/context.rb, line 290
def add_class class_type, given_name, superclass = '::Object'
  # superclass +nil+ is passed by the C parser in the following cases:
  # - registering Object in 1.8 (correct)
  # - registering BasicObject in 1.9 (correct)
  # - registering RubyVM in 1.9 in iseq.c (incorrect: < Object in vm.c)
  #
  # If we later find a superclass for a registered class with a nil
  # superclass, we must honor it.

  # find the name & enclosing context
  if given_name =~ /^:+(\w+)$/ then
    full_name = $1

      # HACK: crashes in actionpack/lib/action_view/helpers/form_helper.rb (metaprogramming)
      unless enclosing then
