Class Method Details

.generate(objects, options = {}) ⇒ void

This method returns an undefined value.

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.

Parameters:

def generate(objects, options = {})
  set_default_options(options)
  options[:objects] = objects
  template(options[:template], :fulldoc, options[:format]).run(options)
end

.register_template_path(path) ⇒ void

This method returns an undefined value.

Registers a new template path in template_paths

Parameters:

  • path (String) —

    a new template path

def register_template_path(path)
  template_paths.push path
end

.render(options = {}) ⇒ String

Renders a template on a 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.

Examples:

Renders an object with html formatting

Engine.render(:format => :html, :object => obj)

Renders without an object

Engine.render(:type => :fulldoc, :otheropts => somevalue)

Parameters:

  • options (Hash) (defaults to: {}) —

    the options hash

Options Hash (options):

  • :format (Symbol) — default: :text —

    the default format

  • :type (Symbol) — default: nil —

    the :object’s type.

  • :template (Symbol) — default: :default —

    the default template

Returns:

  • (String) —

    the rendered template

def render(options = {})
  set_default_options(options)
  mod = template(options[:template], options[:type], options[:format])

  if options[:serialize] != false
    with_serializer(options[:object], options[:serializer]) { mod.run(options) }
  else
    mod.run(options)
  end
end

.template(*path) ⇒ Template

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).

Parameters:

  • path (Array<String, Symbol>) —

    a list of path components

Returns:

  • (Template) —

    the module representing the template

Raises:

  • (ArgumentError) —

    if the path does not exist within one of the template_paths on disk.

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

.template!(path, full_paths = nil) ⇒ Template

Forces creation of a template at path within a full_path.

Parameters:

  • path (String) —

    the path name of the template

  • full_paths (Array<String>) (defaults to: nil) —

    the full path on disk of the template

Returns:

  • (Template) —

    the template module representing the path

.with_serializer(object, serializer) { ... } ⇒ Object

Serializes the results of a block with a serializer object.

Parameters:

Yields:
