  //   1. Always use "//" (in contrast with "/**/")
  //   2. The syntax used is Yardoc (yardoc.org), which is intended for Ruby (se below)
  //   3. `@param` and `@return` types should be preceded by `JS.` when referring to
  //      JavaScript constructors (e.g. `JS.Function`) otherwise Ruby is assumed.
  //   4. `nil` and `null` being unambiguous refer to the respective
  //      objects/values in Ruby and JavaScript
  //   5. This is still WIP :) so please give feedback and suggestions on how
  //      to improve or for alternative solutions
  //
  //   The way the code is digested before going through Yardoc is a secret kept

  // this function which adds stubs for every method name in the compiled file.

  // compiled source to define methods on special case objects when the compiler
  // can not determine the destination object, or the object is a Module
  // instance. This can get called by `Module#define_method` as well.
  //
  // ## Modules
  //
  // Any method defined on a module will come through this runtime helper.
  // The method is added to the module body, and the owner of the method is
  // set to be the module itself. This is used later when choosing which
  // method should show on a class if more than 1 included modules define
  // the same method. Finally, if the module is in `module_function` mode,
  // then the method is also defined onto the module itself.
  //
  // ## Classes
  //
  // This helper will only be called for classes when a method is being
  // defined indirectly; either through `Module#define_method`, or by a
  // literal `def` method inside an `instance_eval` or `class_eval` body. In
  // either case, the method is simply added to the class' prototype. A special
  // exception exists for `BasicObject` and `Object`. These two classes are
  // special because they are used in toll-free bridged classes. In each of
  // these two cases, extra work is required to define the methods on toll-free
  // bridged class' prototypes as well.
  //
  // ## Objects
  //
  // If a simple ruby object is the object, then the method is simply just
  // defined on the object as a singleton method. This would be the case when
  // a method is defined inside an `instance_eval` block.
  //
  // @param obj  [Object, Class] the actual obj to define method for

// Asciidoctor API

/**
 * @namespace
 * @description
 * The main application interface (API) for Asciidoctor.
 * This API provides methods to parse AsciiDoc content and convert it to various output formats using built-in or third-party converters.
 *
 * An AsciiDoc document can be as simple as a single line of content,
 * though it more commonly starts with a document header that declares the document title and document attribute definitions.
 * The document header is then followed by zero or more section titles, optionally nested, to organize the paragraphs, blocks, lists, etc. of the document.
 *
 * By default, the processor converts the AsciiDoc document to HTML 5 using a built-in converter.
 * However, this behavior can be changed by specifying a different backend (e.g., +docbook+).
 * A backend is a keyword for an output format (e.g., DocBook).
 * That keyword, in turn, is used to select a converter, which carries out the request to convert the document to that format.
 *
 * @example
 * asciidoctor.convertFile('document.adoc', { 'safe': 'safe' }) // Convert an AsciiDoc file
 *
 * asciidoctor.convert("I'm using *Asciidoctor* version {asciidoctor-version}.", { 'safe': 'safe' }) // Convert an AsciiDoc string
 *
 * const doc = asciidoctor.loadFile('document.adoc', { 'safe': 'safe' }) // Parse an AsciiDoc file into a document object
 *
 * const doc = asciidoctor.load("= Document Title\n\nfirst paragraph\n\nsecond paragraph", { 'safe': 'safe' }) // Parse an AsciiDoc string into a document object

// Document API

/**
 * The {@link Document} class represents a parsed AsciiDoc document.
 *
 * Document is the root node of a parsed AsciiDoc document.<br/>
 * It provides an abstract syntax tree (AST) that represents the structure of the AsciiDoc document
 * from which the Document object was parsed.
 *
 * Although the constructor can be used to create an empty document object,
 * more commonly, you'll load the document object from AsciiDoc source
 * using the primary API methods on {@link Asciidoctor}.
 * When using one of these APIs, you almost always want to set the safe mode to 'safe' (or 'unsafe')
 * to enable all of Asciidoctor's features.
 *
 * <pre>
 *   var doc = Asciidoctor.load('= Hello, AsciiDoc!', { 'safe': 'safe' })
 *   // => Asciidoctor::Document { doctype: "article", doctitle: "Hello, AsciiDoc!", blocks: 0 }
 * </pre>
 *
 * Instances of this class can be used to extract information from the document or alter its structure.
 * As such, the Document object is most often used in extensions and by integrations.
 *
 * The most basic usage of the Document object is to retrieve the document's title.
 *
 * <pre>
 *  var source = '= Document Title'
 *  var doc = asciidoctor.load(source, { 'safe': 'safe' })
 *  console.log(doc.getTitle()) // 'Document Title'
 * </pre>
 *
 * You can also use the Document object to access document attributes defined in the header, such as the author and doctype.

 * Extensions provide a way to participate in the parsing and converting
 * phases of the AsciiDoc processor or extend the AsciiDoc syntax.
 *
 * The various extensions participate in AsciiDoc processing as follows:
 *
 * 1. After the source lines are normalized, {{@link Extensions/Preprocessor}}s modify or replace
 *    the source lines before parsing begins. {{@link Extensions/IncludeProcessor}}s are used to
 *    process include directives for targets which they claim to handle.
 * 2. The Parser parses the block-level content into an abstract syntax tree.
 *    Custom blocks and block macros are processed by associated {{@link Extensions/BlockProcessor}}s
 *    and {{@link Extensions/BlockMacroProcessor}}s, respectively.
 * 3. {{@link Extensions/TreeProcessor}}s are run on the abstract syntax tree.
 * 4. Conversion of the document begins, at which point inline markup is processed
 *    and converted. Custom inline macros are processed by associated {InlineMacroProcessor}s.
 * 5. {{@link Extensions/Postprocessor}}s modify or replace the converted document.
 * 6. The output is written to the output stream.
 *
 * Extensions may be registered globally using the {Extensions.register} method
 * or added to a custom {Registry} instance and passed as an option to a single
 * Asciidoctor processor.
 *
 * @example
 * asciidoctor.Extensions.register(function () {
 *   this.block(function () {
 *     var self = this;
 *     self.named('shout');
 *     self.onContext('paragraph');
