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

Class Public methods
new() Link
Creates an unnamed empty context with public current visibility
# File ruby/lib/rdoc/context.rb, line 123 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
Instance Public methods
add(klass, name, comment) Link
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 ruby/lib/rdoc/context.rb, line 183 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) Link
Adds an_alias
that is automatically resolved
# File ruby/lib/rdoc/context.rb, line 198 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) Link
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 ruby/lib/rdoc/context.rb, line 225 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') Link
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 ruby/lib/rdoc/context.rb, line 288 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 = $1 enclosing = top_level name = full_name.split(/:+/).last else full_name = child_name given_name if full_name =~ /^(.+)::(\w+)$/ then name = $2 ename = $1 enclosing = @store.classes_hash[ename] || @store.modules_hash[ename] # HACK: crashes in actionpack/lib/action_view/helpers/form_helper.rb (metaprogramming) unless enclosing then # try the given name at top level (will work for the above example) enclosing = @store.classes_hash[given_name] || @store.modules_hash[given_name] return enclosing if enclosing # not found: create the parent(s) names = ename.split('::') enclosing = self names.each do |n| enclosing = enclosing.classes_hash[n] || enclosing.modules_hash[n] || enclosing.add_module(RDoc::NormalModule, n) end end else name = full_name enclosing = self end end # fix up superclass if full_name == 'BasicObject' then superclass = nil elsif full_name == 'Object' then superclass = '::BasicObject' end # find the superclass full name if superclass then if superclass =~ /^:+/ then superclass = $' #' else if superclass =~ /^(\w+):+(.+)$/ then suffix = $2 mod = find_module_named($1) superclass = mod.full_name + '::' + suffix if mod else mod = find_module_named(superclass) superclass = mod.full_name if mod end end # did we believe it was a module? mod = @store.modules_hash.delete superclass upgrade_to_class mod, RDoc::NormalClass, mod.parent if mod # e.g., Object < Object superclass = nil if superclass == full_name end klass = @store.classes_hash[full_name] if klass then # if TopLevel, it may not be registered in the classes: enclosing.classes_hash[name] = klass # update the superclass if needed if superclass then existing = klass.superclass existing = existing.full_name unless existing.is_a?(String) if existing if existing.nil? || (existing == 'Object' && superclass != 'Object') then klass.superclass = superclass end end else # this is a new class mod = @store.modules_hash.delete full_name if mod then klass = upgrade_to_class mod, RDoc::NormalClass, enclosing klass.superclass = superclass unless superclass.nil? else klass = class_type.new name, superclass enclosing.add_class_or_module(klass, enclosing.classes_hash, @store.classes_hash) end end klass.parent = self klass end

to the modules or classes Hash
self_hash
, and to all_hash

), unless done_documenting
is true
. Sets the parent
of mod
to self
, and its section
to current_section
. Returns mod
.
# File ruby/lib/rdoc/context.rb, line 404 def add_class_or_module mod, self_hash, all_hash mod.section = current_section # TODO declaring context? something is # wrong here... mod.parent = self mod.full_name = nil mod.store = @store unless @done_documenting then self_hash[mod.name] = mod # this must be done AFTER adding mod to its parent, so that the full # name is correct: all_hash[mod.full_name] = mod if @store.unmatched_constant_alias[mod.full_name] then to, file = @store.unmatched_constant_alias[mod.full_name] add_module_alias mod, mod.name, to, file end end mod end

which should be an RDoc::Extend
