| * |
| * ## 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. |

| * |
| * @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 |
| * object to be modified. |
| * |

| * @returns {Grammar} The new grammar object. |
