This module manages all creation, handling and rendering of {Template} objects.
To create a template object at a path, use {template}.
To render a template, call {render}.
To register a template path in the lookup paths, call {register_template_path}.
Passes a set of objects to the :fulldoc template for full documentation generation. This is called by {CLI::Yardoc} to most commonly perform HTML documentation generation.
@param [Array<CodeObjects::Base>] objects a list of {CodeObjects::Base}
objects to pass to the template
@param [Hash] options (see {render}) @return [void]
# File lib/yard/templates/engine.rb, line 100 def generate(objects, options = {}) options = set_default_options(options) options.objects = objects options.object = Registry.root template(options.template, :fulldoc, options.format).run(options) end
Registers a new template path in {template_paths}
@param [String] path a new template path @return [void]
# File lib/yard/templates/engine.rb, line 20 def register_template_path(path) template_paths.push path end
Renders a template on a {CodeObjects::Base code object} using a set of default (overridable) options. Either the :object or :type keys must be provided.
If a :serializer key is provided and :serialize is not set to false, the rendered contents will be serialized through the {Serializers::Base} object. See {with_serializer}.
@example Renders an object with html formatting
Engine.render(:format => :html, :object => obj)
@example Renders without an object
Engine.render(:type => :fulldoc, :otheropts => somevalue)
@param [Hash] options the options hash @option options [Symbol] :format (:text) the default format @option options [Symbol] :type (nil) the :object's type. @option options [Symbol] :template (:default) the default template @return [String] the rendered template
# File lib/yard/templates/engine.rb, line 81 def render(options = {}) options = set_default_options(options) mod = template(options.template, options.type, options.format) if options.serializer && options.serialize != false with_serializer(options.object, options.serializer) { mod.run(options) } else mod.run(options) end end
Creates a template module representing the path. Searches on disk for the first directory named path (joined by '/') within the template paths and builds a template module for. All other matching directories in other template paths will be included in the generated module as mixins (for overriding).
@param [Array<String, Symbol>] path a list of path components @raise [ArgumentError] if the path does not exist within one of the
{template_paths} on disk.
@return [Template] the module representing the template
# File lib/yard/templates/engine.rb, line 34 def template(*path) from_template = nil from_template = path.shift if path.first.is_a?(Template) path = path.join('/') full_paths = find_template_paths(from_template, path) path = File.cleanpath(path).gsub('../', '') raise ArgumentError, "No such template for #{path}" if full_paths.empty? mod = template!(path, full_paths) mod end
Forces creation of a template at path within a full_path.
@param [String] path the path name of the template @param [Array<String>] full_paths the full path on disk of the template @return [Template] the template module representing the path
# File lib/yard/templates/engine.rb, line 52 def template!(path, full_paths = nil) full_paths ||= [path] full_paths = [full_paths] unless full_paths.is_a?(Array) name = template_module_name(full_paths.first) begin; return const_get(name); rescue NameError; end mod = const_set(name, Module.new) mod.send(:include, Template) mod.send(:initialize, path, full_paths) mod end
Serializes the results of a block with a serializer object.
@param [CodeObjects::Base] object the code object to serialize @param [Serializers::Base] serializer the serializer object @yield a block whose result will be serialize @yieldreturn [String] the contents to serialize @see Serializers::Base
# File lib/yard/templates/engine.rb, line 114 def with_serializer(object, serializer, &block) output = nil filename = serializer.serialized_path(object) if serializer.respond_to?(:basepath) filename = File.join(serializer.basepath, filename) end log.capture("Generating #{filename}", nil) do serializer.before_serialize if serializer output = yield if serializer serializer.serialize(object, output) serializer.after_serialize(output) end end output end
