- *
- * ## 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.
- *

- * 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.
- *
- * ```js
- * var oldMarkup = Prism.languages.markup;
- * var newMarkup = Prism.languages.insertBefore('markup', 'comment', { ... });
- *
- * assert(oldMarkup !== Prism.languages.markup);
- * assert(newMarkup === Prism.languages.markup);
- * ```
- *
- * @param {string} inside The property of `root` (e.g. a language id in `Prism.languages`) that contains the
- * object to be modified.
- * @param {string} before The key to insert before.
- * @param {Grammar} insert An object containing the key-value pairs to be inserted.
- * @param {Object<string, any>} [root] The object containing `inside`, i.e. the object that contains the
