* By default , Prism will attempt to highlight all code elements ( by calling { @ link Prism . highlightAll } ) on the
* current page after the page finished loading . This might be a problem if e . g . you wanted to asynchronously load
* additional languages or plugins yourself .
*
* By setting this value to ` true ` , Prism will not automatically highlight all code elements on the page .
*
* You obviously have to change this value before the automatic highlighting started . To do this , you can add an
* empty Prism object into the global scope before loading the Prism script like this :
*
* ` ` ` js
* window . Prism = window . Prism || { } ;
* Prism . manual = true ;
* // add a new <script> to load Prism's script

* By default , if Prism is in a web worker , it assumes that it is in a worker it created itself , so it uses
* ` addEventListener ` to communicate with its parent instance . However , if you ' re using Prism manually in your
* own worker , you don ' t want it to do this .
*
* By setting this value to ` true ` , Prism will not add its own listeners to the worker .
*
* You obviously have to change this value before Prism executes . To do this , you can add an

* Creates a deep copy of the language with the given id and appends the given tokens .
*
* If a token in ` redef ` also appears in the copied language , then the existing token in the copied language
* will be overwritten at its original position .
*
* # # Best practices
*
* Since the position of overwriting tokens ( token in ` redef ` that overwrite tokens in the copied language )
* doesn ' t matter , they can technically be in any order . However , this can be confusing to others that trying to
* understand the language definition because , normally , the order of tokens matters in Prism grammars .
*
* Therefore , it is encouraged to order overwriting tokens according to the positions of the overwritten tokens .
* Furthermore , all non - overwriting tokens should be placed after the overwriting ones .
*
* @ param { string } id The id of the language to extend . This has to be a key in ` Prism.languages ` .
* @ param { Grammar } redef The new tokens to append .
* @ returns { Grammar } The new language created .
* @ public
* @ example
* Prism . languages [ 'css-with-colors' ] = Prism . languages . extend ( 'css' , {
* // Prism.languages.css already has a 'comment' token, so this token will overwrite CSS' 'comment' token
* // at its original position
* 'comment' : { ... } ,
* // CSS doesn't have a 'color' token, so this token will be appended
* 'color' : /\b(?:red|green|blue)\b/
* } ) ;

/ * *
* Inserts tokens _before _ another token in a language definition or any other grammar .
*
* # # Usage
*
* This helper method makes it easy to modify existing languages . For example , the CSS language definition
* not only defines CSS highlighting for CSS documents , but also needs to define highlighting for CSS embedded
* in HTML through ` <style> ` elements . To do this , it needs to modify ` Prism.languages.markup ` and add the
* appropriate tokens . However , ` Prism.languages.markup ` is a regular JavaScript object literal , so if you do
* this :
*
* ` ` ` js
* Prism . languages . markup . style = {
* // token
* } ;
* ` ` `
*
* then the ` style ` token will be added ( and processed ) at the end . ` insertBefore ` allows you to insert tokens
* before existing tokens . For the CSS example above , you would use it like this :
*
* ` ` ` js
* Prism . languages . insertBefore ( 'markup' , 'cdata' , {
* 'style' : {
* // token
* }
* } ) ;
* ` ` `
*
* # # Special cases
*
* If the grammars of ` inside ` and ` insert ` have tokens with the same name , the tokens in ` inside ` ' s grammar
* will be ignored .
*
* This behavior can be used to insert tokens after ` before ` :
*
* ` ` ` js
* Prism . languages . insertBefore ( 'markup' , 'comment' , {
* 'comment' : Prism . languages . markup . comment ,
* // tokens after 'comment'
* } ) ;
* ` ` `
*
* # # Limitations
*
* The main problem ` insertBefore ` has to solve is iteration order . Since ES2015 , the iteration order for object
* properties is guaranteed to be the insertion order ( except for integer keys ) but some browsers behave
* differently when keys are deleted and re - inserted . So ` insertBefore ` can ' t be implemented by temporarily
* deleting properties which is necessary to insert at arbitrary positions .
*
* To solve this problem , ` insertBefore ` doesn ' t actually insert the given tokens into the target object .
* Instead , it will create a new object and replace all references to the target object with the new one . This
* can be done without temporarily deleting properties , so the iteration order is well - defined .
*
* However , only references that can be reached from ` Prism.languages ` or ` insert ` will be replaced . I . e . if
* you hold the target object in a variable , then the value of the variable will not change .
*

* Token streams have to fulfill a few properties that are assumed by most functions ( mostly internal ones ) that process
* them .
*
* 1. No adjacent strings .
* 2. No empty strings .
*
* The only exception here is the token stream that only contains the empty string and nothing else .

* @ param { string } language The name of current language .
