-# Why VNote
-## Markdown Editor & Notes Management
-VNote tries to be a powerful Markdown editor with notes management, or a note-taking application with pleasant Markdown support. If you are a fan of Markdown and enjoy writing Markdown notes for study, work, and life, VNote is the right tool for you.
-
-## Pleasant Markdown Experience
-### Insights About Markdown
-Markdown, as a simple mark language, unlike rich text, was born with a **gap between edit and read**. There are about three ways to handle this gap:
-
-1. As one extreme, some editors just treat Markdown as **plain text**. Users may lose themselves in the messy black characters. It is hard to keep track of the information of the note.
-2. Most Markdown editors use two panels to **edit and preview Markdown notes simultaneously**. It makes things easier since users could see a pleasant typesetting and layout while editing the text. However, two panels may occupy the whole screen and users keep moving eyes left and right which will be a big distraction.
-3. As another extreme, some editors convert the Markdown elements in place immediately after the typing, which makes editing Markdown just like editing rich text document in Word.
-
-Since most editors choose the second way to handle the gap, people always think of preview when it comes to Markdown. It may be a misunderstanding about Markdown. Designed as a simple mark language, Markdown is intended to help to keep track of the information of the text when editing and provide a beautiful typesetting when reading after being converted to HTML.
-
-### Tradeoff: VNote's Way
-VNote tries to minimize the gap and provide the best-effort *WYSIWYG* for Markdown via tuned **syntax highlights** and some other features. By helping to keep track of the content, there is no need to preview or alter the text immediately after being typed.
-
-# Features
-## Notebook-Based Notes Management
-VNote uses **notebooks** to hold your notes. Like OneNote, a notebook can be hosted on any location on your system. A notebook is designed to represent one account. For example, you could have one notebook hosted on local file system and another notebook hosted on an OwnCloud server. This is really useful when notes require different levels of security.
-
-A notebook corresponds to a self-contained folder (called the *Root Folder* of the notebook) in the file system. You could copy the folder to another location (or on another computer) and import it into VNote.
-
-A notebook could have infinite levels of folders. VNote supports copying or moving folders or notes within or between notebooks.
-
-## Simple Notes Management
-All your notes are managed by some plaintext configuration files and stored as plaintext files. You could access your notes without VNote. You could use external file synchronization services to synchronize your notes and import them on another machine.
-
-VNote supports both Markdown (suffix `md`) and rich text notes.
-
-## Syntax Highlight
-VNote supports accurate syntax highlight for Markdown. Tuning the style of the highlight, VNote enables you to keep track of your document easily.
-
-VNote also supports **syntax highlight for fenced code blocks** in edit mode in Markdown, which is **superior** than almost all current Markdown editors.
-
-![Syntax Highlight](screenshots/_1513485266_1616037517.png)
-
-## In-Place Preview
-VNote supports powerful **in-place preview** for images, diagrams, and formulas in edit mode.
-
-![In-Place Preview](screenshots/_inplacepre_1525155248_405615820.png)
-
-## Pleasant Image Experience
-Just paste your image into the Markdown note, VNote will manage all other stuffs. VNote stores images in a specified folder in the same folder with the note. VNote will pop up a window to preview the image when you insert an image. Furthermore, VNote will delete the useless image files automatically after you remove the image links.
-
-## Universal Entry & Full-Text Search
-VNote has powerful built-in full-text search with **Regular Expression** and **Fuzzy Search** support. The search could be executed within all notebooks, current notebook, or current folder, targeted at name or content.
-
-Like the `CtrlP` in Vim, VNote supports **Universal Entry** to reach anything by typing in a simple input.
-
-![Universal Entry](screenshots/_universale_1522894821_465772669.png)
-
-## Interactive Outline Viewer In Read & Edit Mode
-VNote provides a user-friendly outline viewer for both edit and view mode. The outline viewer is a responsive item tree instead of a segment of HTML.
-
-## Powerful Shortcuts
-VNote supports many pleasant and powerful shortcuts which facilitate your editing, including **Vim Mode**, **Captain Mode**, and **Navigation Mode** which enable you to work without the mouse.
-
-Please refer to the [shortcuts help](src/resources/docs/shortcuts_en.md) in the help menu for more details.
-
-## Highly Configurable
-In VNote, almost everything is configurable, such as background color, font, and Markdown style. VNote uses a plaintext file to record all your configuration, so you could just copy that file to initialize a new VNote on another computer.

-# VNoteのわけ
-## Markdown編集とノート管理
-VNoteは、ノート管理機能のついた協力なMarkdownエディタ、あるいは快適なMarkdownサポートつきのノート作成アプリケーションを目指しています。もしMarkdownのファンで、勉強や仕事、人生のためにMarkdownのノートを書くのなら、VNoteはあなたにとって正しいツールです。
-
-## 快適なマークダウン体験
-### Markdownについての洞察
-Markdownは、リッチテキストとは異なり、編集と読み取りの間にある**ギャップ**を持って生まれた、シンプルなマークアップ言語です。このギャップを扱うには、3つの方法があります。
-
-1. 一つの極端な例として、エディタの中には、Markdownを**プレーンテキスト**として扱うだけのものもある。ユーザーは、ごちゃごちゃした黒い文字で自分を失うことがあります。メモの情報を追跡するのは難しくなる。
-2. ほとんどのMarkdownエディターは、**編集とプレビューを同時に行うために、2つのパネルを使用します**。ユーザーはテキストの編集中に、楽しいタイプの設定とレイアウトを見ることができるので、より簡単になります。しかし、2つのパネルが画面全体を占め、ユーザは目を左右に動かすことになり、大きな混乱を招くことになりかねません。
-3. もう一つの極端な点として、編集の直後にMarkdown要素を変換するエディタもあり、Wordのリッチテキスト文書を編集するのと同じように、Markdownを編集することができます。
-
-ほとんどのエディタは、ギャップを処理するための2番目の方法を選んでいるので、Markdownをつかうときは、常にプレビューを考えていることになります。これは、Markdownの誤解かもしれません。シンプルなマーク言語として設計されたMarkdownは、編集時にテキストの情報を記録し、HTMLに変換された後に美しいタイプの設定を提供することを目的としています。
-
-### トレードオフ:VNoteの方法
-VNoteは、チューニングされた**構文ハイライト**とその他の機能によって、ギャップを最小限に抑えて、Markdownのためにベストエフォート*WYSIWYG*を提供します。コンテンツを追跡することを助けることにより、テキストを入力した直後にテキストをプレビューしたり変更する必要がなくなります。
-
-# 機能
-## ノートブック・ベースのノート管理
-VNoteは、**ノートブック**を使用してノートを管理することができます。OneNoteと同様に、ノートブックはシステム上の任意の場所にホストすることができます。ノートブックは1つのアカウントを表すように設計されています。たとえば、ローカル・ファイルシステムで管理されているノートブックと、OwnCloudサーバ上に保存されている別のノートブックをもつことができます。これは、メモが異なるレベルのセキュリティを必要とする場合に、実際に役立ちます。
-
-ノートブックは、ファイルシステム内の自己完結型フォルダ(ノートブックの*Rootフォルダ*と呼ばれます)に対応しています。フォルダを別の場所(または別のコンピュータ)にコピーして、VNoteにインポートすることができます。
-
-ノートブックは、無限レベルのフォルダを持つことができます。VNoteでは、ノートブック内またはノートブック間でフォルダやノートをコピーまたは移動することができます。 
-
-## シンプルなノート管理
-すべてのメモは、平文の設定ファイルによって管理され、平文ファイルとして格納されます。ノートは、VNOTEなしでアクセスできます。外部のファイル同期サービスを使用して、ノートを同期させたり、別のマシンにインポートすることができます。
-
-VNoteは、Markdown(拡張子`md`)とリッチテキストノートの両方をサポートしています。
-
-## 構文ハイライト
-VNoteでは、Markdownの正確な構文強調表示をサポートしています。ハイライトのスタイルを調整することで、VNoteを使用してドキュメントを簡単に追跡することができます。
-
-また、VNoteは、**Fenceされたコードブロックに対する**構文ハイライトをサポートしています。これは、現在のあらゆるMarkdownエディタよりも**優れています**。
-

-## インプレイスプレビュー
-VNoteは、編集モードでのイメージ、図、数式の強力な**その場プレビュー**をサポートしています。

-画像をMarkdownに貼り付けするだけで、VNoteは他のすべてのものを管理することになります。VNoteは、同じフォルダ内の指定されたフォルダに、ノートとともに画像を格納します。VNoteは、画像を挿入するときに画像プレビューするウィンドウをポップアップ表示させます。また、VNoteは、画像リンクを削除した後に、自動的に画像ファイルを削除します。
-
-## ユニバーサルエントリと全文検索
-VNote には、**正規表現**と**ファジー検索**サポートのある、強力な全文検索が組み込まれています。検索は、すべてのノートブック、現在のノートブック、または現在のフォルダ、名前またはコンテンツを対象に実行することができます。
-
-VNoteは、Vimでの`Ctrl+P`のように、**ユニバーサルエントリ**機能をサポートし、シンプルな入力であらゆる機能へ到達できます。
-

-
-## 読み込み&編集モードのインタラクティブなアウトライン表示
-VNoteでは、編集モードと閲覧モードの両方でユーザフレンドリなアウトラインビューアが提供されています。アウトライン・ビューアは、HTMLのセグメントではなく、応答するアイテム・ツリーです。
-
-## 強力なショートカット
-VNoteは、<x/>Vim Mode**、**キャプテンモード**、<x/>、**ナビゲーションモード**など、編集を容易にする強力なショートカットをサポートしています。これにより、マウスを使用せずに作業を行うことができます。
-
-詳細については、ヘルプメニューの[ショートカットヘルプ](src/resources/docs/shortcuts_en.md)を参照してください。
-
-## 柔軟に調整可能
-VNoteでは、背景色、フォント、マークダウンなど、ほとんどすべてのものが調整可能です。VNoteは平文ファイルを使ってすべての構成を記録しますので、そのファイルをコピーすれば、別のコンピュータで新しいVNoteを初期化することができます。

-# 开发 VNote 的动机
-## Markdown 编辑器与笔记管理
-VNote 设计为带有笔记管理功能的 Markdown 编辑器，或者有良好 Markdown 支持的笔记软件。如果您喜欢 Markdown 并经常在学习、工作和生活中使用 Markdown 记录笔记，那么 VNote 就是一个适合您的工具。
-
-## 舒适的 Markdown 体验
-### Markdown 的本质
-Markdown 作为一个简单标记语言，不像富文本，它的编辑和阅读有着与生俱来的隔阂。一般目前大概有三类方法来处理这个隔阂：
-
-1. 作为一个极端，一些编辑器只是将 Markdown 作为无格式的纯文本处理。用户很容易在密密麻麻的黑漆漆的一片文字中找不着方向。
-2. 大部分编辑器使用两个面板来同时编辑和预览 Markdown 笔记。从而，用户可以在编辑的同时看到优美的排版和布局。但是，两个面板基本会占据了整个屏幕，而用户的目光焦点左右频繁移动，往往也会使得用户无法专注编辑。
-3. 作为另一个极端，一些编辑器在用户输入文本后立即将 Markdown 的标记转换为 HTML 元素，使得编写 Markdown 如同在 Word 文档里面编写富文本一样。
-
-由于几乎所有的编辑器都选择第二种方法来处理隔阂，一提到 Markdown 人们往往会想起预览。这可能是对 Markdown 的一个最大的误解了。设计为一个简单的标记语言，Markdown 的设计初衷就是为了在编辑的时候方便帮助跟踪文本的信息，而又能在阅读的时候被转换为 HTML 为发布提供美观的排版输出。所以，Markdown 本身就应该在编辑的时候能够方便地跟踪和掌控文本的信息和脉络，而不需要通过预览这种接近饮鸩止渴的方法来方便编辑。
-
-### 折中：VNote 的方案
-VNote 尝试通过精心调配的**语法高亮**和其他一些特性，来最大程度地减小 Markdown 的这种割裂感，尽可能地提供一个*所见即所得*的编辑体验。用户在编辑的时候就能有效第把握内容脉络，也就没有必要进行预览或者强制更改文本为 HTML 元素了。
-
-# 功能
-## 基于笔记本的管理
-VNote 使用 **笔记本** 来管理笔记。类似于 OneNote，一个笔记本可以保存在系统上的任意位置。一个笔记本对应于一个账户的概念。例如，您可以在本地文件系统上有一个笔记本，另外在某台 OwnCloud 服务器上保存另一个笔记本。当不同的笔记有不同的保密要求时，独立的笔记本就非常适用了。
-
-一个笔记本对应于文件系统上的一个独立完整的文件夹（称为笔记本的 **根目录** ）。您可以将该文件夹拷贝到其他位置（或者另一台计算机上），然后将其导入到 VNote 中。
-
-VNote 支持一个笔记本中包含无限层级的文件夹。VNote 支持在笔记本内或笔记本间拷贝或剪切文件夹和笔记。
-
-## 直观的笔记管理
-所有笔记被保存为纯文本而且通过纯文本的配置文件进行管理。即使没有 VNote，您也能方便访问您的数据。这样，您也可以使用第三方的文件同步服务来同步您的笔记，并在另一台计算机上导入到 VNote 中。
-
-VNote 支持 Markdown 和富文本笔记，其中 Markdown 笔记必须以 `md` 为后缀名。
-
-## 语法高亮
-VNote 支持精确的 Markdown 语法高亮。通过精心调试的高亮样式，VNote 使得您能够轻松跟踪和阅读您的文档。
-
-VNote 还支持 Markdown 编辑模式中代码块的语法高亮。目前的 Markdown 编辑器中绝大部分都尚不支持该特性。
-
-![Syntax Highlight](screenshots/_1513485266_1616037517.png)
-
-## 原地预览
-VNote 支持在编辑时原地预览图片、图表和公式。
-
-![In-Place Preview](screenshots/_inplacepre_1525155248_405615820.png)
-
-## 良好的图片体验
-编辑时，支持像其他富文本编辑器一样直接粘贴插入图片，VNote 会帮您管理所插入的图片。VNote 将这些图片保存在和笔记同一目录下的一个指定目录中。插入图片时，VNote 会弹出一个窗口预览即将要插入的图片。另外，当您移除笔记中的图片链接时，VNote 会自动删除对应的图片文件。
-
-## 通用入口和全文搜索
-VNote 内置强大的全文搜索，支持**正则表达式**和**模糊搜索**。搜索可以指定范围，包括全部笔记本、当前笔记本和当前文件夹，也可以指定目标，如名字或内容。
-
-类似于 Vim 中的 `Ctrl+P`，VNote 支持**通用入口**，可以在一个输入框中进行搜索或跳转。
-
-![Universal Entry](screenshots/_universale_1522894821_465772669.png)
-
-## 编辑和阅读模式中的交互式大纲视图
-VNote 为编辑和预览模式都提供了一个用户友好的大纲视图。该大纲视图是一个项目树，而不是简单地插入一段 HTML。
-
-## 强大的快捷键
-VNote 提供很多快捷键，从而提供一个愉悦的编辑体验。其中包括 **Vim模式**、**舰长模式** 和 **导航模式**，它们能让您完全摆脱鼠标进行操作。
-
-更多细节请参考帮助菜单中的[快捷键帮助](src/resources/docs/shortcuts_zh.md)。
-
-## 高度可定制
-在 VNote 中，几乎一切都是可以定制的，例如背景颜色、字体以及 Markdown 样式等。VNote 使用一个纯文本文件来记录您的所有配置，因此通过拷贝该文件就能够很快地在另一台电脑上初始化一个新的 VNote。

-The Syntax of PEG Markdown Highlight Stylesheets
-================================================
-
-[PEG Markdown Highlight][pmh] includes a parser for stylesheets that define how different Markdown language elements are to be highlighted. This document describes the syntax of these stylesheets.
-
-[pmh]: http://hasseg.org/peg-markdown-highlight/
-
-
-Example
--------
-
-Here is a quick, simple example of a stylesheet:
-
-<style>
-.codetable { border-collapse: collapse; }
-.codetable .left { text-align: right; padding-right: 10px; }
-.codetable .right { text-align: left; padding-left: 10px; }
-.codetable .content { font-family: monospace; background: #eee; padding: 0 5px; }
-.codetable .comment { color: #174EB3; }
-.codetable .rule { color: #491B8F; }
-.codetable .attrname { color: #48B317; }
-.codetable .attrvalue { color: #A65C1F; }
-</style>
-
-<table class="codetable">
-<tr>
-    <td class="left"></td>
-    <td class="content"># The first comment lines</td>
-    <td class="right"></td>
-</tr>
-<tr>
-    <td class="left"></td>
-    <td class="content"># describe the stylesheet.</td>
-    <td class="right"></td>
-</tr>
-<tr>
-    <td class="left"></td>
-    <td class="content">&nbsp;</td>
-    <td class="right"></td>
-</tr>
-<tr>
-    <td class="left"><span class="rule">Style rule &rarr;</span></td>
-    <td class="content"><span class="rule">editor:</span></td>
-    <td class="right"></td>
-</tr>
-<tr>
-    <td class="left"></td>
-    <td class="content">&nbsp;&nbsp;foreground: ff0000 <span class="comment"># red text</span></td>
-    <td class="right"><span class="comment">&larr; Comment</span></td>
-</tr>
-<tr>
-    <td class="left"><span class="attrname">Attribute name &rarr;</span></td>
-    <td class="content">&nbsp;&nbsp;<span class="attrname">font-family</span>: <span class="attrvalue">Consolas</span></td>
-    <td class="right"><span class="attrvalue">&larr; Attribute value</span></td>
-</tr>
-<tr>
-    <td class="left"></td>
-    <td class="content">&nbsp;</td>
-    <td class="right"></td>
-</tr>
-<tr>
-    <td class="left"></td>
-    <td class="content">EMPH:</td>
-    <td class="right"></td>
-</tr>
-<tr>
-    <td class="left"></td>
-    <td class="content">&nbsp;&nbsp;font-size: 14</td>
-    <td class="right"></td>
-</tr>
-<tr>
-    <td class="left"></td>
-    <td class="content">&nbsp;&nbsp;font-style: bold, underlined</td>
-    <td class="right"></td>
-</tr>
-</table>
-
-
-Style Rules
------------
-
-A stylesheet is composed of one or more *rules*. Rules are separated from each other by **empty lines** like so:
-
-    H2:
-    foreground: ff0000
-    
-    H3:
-    foreground: 00ff00
-
-Each begins with the ***name* of the rule**, which is always on its own line, and may be one of the following:
-
-- **`editor`**: Styles that apply to the whole document/editor
-- **`editor-current-line`**: Styles that apply to the current line in the editor (i.e. the line where the caret is)
-- **`editor-selection`**: Styles that apply to the selected range in the editor when the user makes a selection in the text
-- A Markdown element type (like `EMPH`, `REFERENCE` or `H1`): Styles that apply to occurrences of that particular element. The supported element types are:
-    - **`LINK`:** Explicit link (like `[click here][ref]`)
-    - **`AUTO_LINK_URL`:** Implicit URL link (like `<http://google.com>`)
-    - **`AUTO_LINK_EMAIL`:** Implicit email link (like `<first.last@google.com>`)
-    - **`IMAGE`:** Image definition
-    - **`REFERENCE`:** Reference (like `[id]: http://www.google.com`)
-    - **`CODE`:** Inline code
-    - **`EMPH`:** Emphasized text
-    - **`STRONG`:** Strong text
-    - **`LIST_BULLET`:** Bullet for an unordered list item
-    - **`LIST_ENUMERATOR`:** Enumerator for an ordered list item
-    - **`H1`:** Header, level 1
-    - **`H2`:** Header, level 2
-    - **`H3`:** Header, level 3
-    - **`H4`:** Header, level 4
-    - **`H5`:** Header, level 5
-    - **`H6`:** Header, level 6
-    - **`BLOCKQUOTE`:** Blockquote marker
-    - **`VERBATIM`:** Block of code
-    - **`HRULE`:** Horizontal rule
-    - **`HTML`:** HTML tag
-    - **`HTML_ENTITY`:** HTML special entity definition (like `&hellip;`)
-    - **`HTMLBLOCK`:** Block of HTML
-    - **`COMMENT`:** (HTML) Comment
-    - **`NOTE`:** Note
-    - **`STRIKE`:** Strike-through
-
-The name may be optionally followed by an assignment operator (either `:` or `=`):
-
-    H1:
-    foreground: ff00ff
-    
-    H2 =
-    foreground: ff0000
-    
-    H3
-    foreground: 00ff00
-
-The **order of style rules is significant**; it defines the order in which different language elements should be highlighted. *(Of course applications that use PEG Markdown Highlight and the style parser may disregard this and highlight elements in whatever order they desire.)*
-
-After the name of the rule, there can be one or more *attributes*.
-
-
-Style Attributes
-----------------
-
-Attribute assignments are each on their own line, and they consist of the *name* of the attribute as well as the *value* assigned to it. An assignment operator (either `:` or `=`) separates the name from the value:
-
-    attribute-name: value
-    attribute-name= value
-
-Attribute assignment lines **may be indented**.
-
-### Attribute Names and Types
-
-The following is a list of the names of predefined attributes, and the values they may be assigned:
-
-- `foreground-color` *(aliases: `foreground` and `color`)*
-    - See the *Color Attribute Values* subsection for information about valid values for this attribute.
-- `background-color` *(alias: `background`)*
-    - See the *Color Attribute Values* subsection for information about valid values for this attribute.
-- `caret-color` *(alias: `caret`)*
-    - See the *Color Attribute Values* subsection for information about valid values for this attribute.
-- `strike-color` *(alias: `strike`)*
-    - See the *Color Attribute Values* subsection for information about valid values for this attribute.
-- `font-size`
-    - An integer value for the font size, *in points* (i.e. not in pixels). The number may have a textual suffix such as `pt`.
-    - If the value begins with `+` or `-`, it is considered *relative* to some base font size (as defined by the host application). For example, the value `3` defines the font size as 3 (absolute) while `+3` defines it as +3 (relative), i.e. 3 point sizes larger than the base font size.
-- `font-family`
-    - A comma-separated list of one or more arbitrary font family names. *(It is up to the application that uses the PEG Markdown Highlight library to resolve this string to actual fonts on the system.)*
-- `font-style`
-    - A comma-separated list of one or more of the following:
-        - `italic`
-        - `bold`
-        - `underlined`
-
-Applications may also include support for any **custom attribute names and values** they desire &mdash; attributes other than the ones listed above will be included in the style parser results, with their values stored as strings.
-
-
-## Color Attribute Values
-
-Colors can be specified either in **RGB** (red, green, blue) or **ARGB** (alpha, red, green, blue) formats. In both, each component is a two-character hexadecimal value (from `00` to `FF`):
-
-    foreground: ff00ee  # red = ff, green = 00, blue = ee (and implicitly, alpha = ff)
-    background: 99ff00ee  # alpha = 99, red = ff, green = 00, blue = ee
-
-
-Comments
---------
-
-Each line in a stylesheet may have a comment. The `#` character begins a line comment that continues until the end of the line:
-
-    # this line has only this comment
-    H1:  # this line has a style rule name and then a comment
-    foreground: ff0000  # this line has an attribute and then a comment

-# Markdown Guide
-This is a quick guide [^1] for Markdown, a lightweight and easy-to-use syntax for writing.
-
-## What is Markdown?
-Markdown is a way to style text via a few simple marker characters. You could write the document in plain text and then read it with a beautiful typesetting.
-
-There is no a standard Markdown syntax and many editor will add its own additional syntax. VNote supports only the widely-used basic syntax.
-
-## How to Use Markdown?
-If you are new to Markdown, it is better to learn the syntax elements step by step. Knowing headers and emphasis is enough to make you survive. You could learn another new syntax and practise it every one or two days.
-
-## Syntax Guide
-Here is an overview of Markdown syntax supported by VNote.
-
-### Headers
-```md
-# This is an <h1> tag
-## This is an <h2> tag
-###### This is an <h6> tag
-```
-
-**Notes**:
-
-- At least one space is needed after the `#`;
-- A header should occupy one entire line;
-
-### Emphasis
-```md
-*This text will be italic*  
-_This text will be italic_  
-
-**This text will be bold**  
-__This text will be bold__
-```
-
-**Notes**:
-
-- `*` is recommended in VNote;
-- If the render failed, try to add an additional space before the first `*` and after the last `*`. The space is necessary if the surrounded text begins or ends with full width punctuation;
-- VNote provides shortcuts `Ctrl+I` and `Ctrl+B` to insert italic and bold text;
-
-### Lists
-#### Unordered
-```md
-* Item 1  
-This is a text under Item 1. Notice that there are two spaces at the end above.
-* Item 2
-    * Item 2a
-    * Item 2b
-* Item 3
-
-To end a list, there should be one empty line above.
-```
-
-#### Ordered
-```md
-1. Item 1
-1. Item 2  
-Notice that the sequence number is irrelevant. Markdown will change the sequence automatically when renderring.
-3. Item 3
-    1. Item 3a
-    2. Item 3b
-4. Item 4
-```
-
-### Tables
-```md
-| col 1 | col 2 | col 3 |
-| --- | --- | --- |
-| cell1 | cell2 | cell3 |
-| cell4 | cell5 | cell6 |
-```
-
-### Images and Links
-```md
-![Image Alt Text](/url/to/image.png "Optional Text")
-
-![Image Alt Text](/url/to/image.png "Image specified with width and height" =800x600)
-
-![Image Alt Text](/url/to/image.png =800x600)
-
-![Image Alt Text](/url/to/image.png "Image specified with width" =800x)
-
-![Image Alt Text](/url/to/image.png "Image specified with height" =x600)
-
-[Link Text](/url/of/the/link)
-```
-
-**Notes**:
-
-- It is not recommended to use image links in reference format. VNote will not preview those images.
-- Specifying size of image is supported only in **markdown-it**.
-
-### Blockquotes
-```md
-As VNote suggests:
-
-> VNote is the best Markdown note-taking application
-> ever.  
->
-> THere is two spaces after `ever.` above to insert a
-> new line.
-```
-
-**Notes**:
-
-- Space is needed after the marker `>`;
-- You could just add only one `>` at the first line;
-
-### Fenced Code Block
-    ```lang
-    This is a fenced code block.
-    ```
-
-    ~~~
-    This is another fenced code block.
-    ~~~
-
-**Notes**:
-
-- `lang` is optional to specify the language of the code; if not specified, VNote won't highlight the code;
-
-### Diagrams
-
-> You need to enable Flowchart.js or Mermaid or WaveDrom in the `Markdown` menu and restart current opened tabs.
-
-VNote supports the following engines to draw diagrams. You should specify particular language of the fenced code block and write the definition of your diagram within it.
-
-- [Flowchart.js](http://flowchart.js.org/) for *flowchart* with language `flow` or `flowchart`;
-- [Mermaid](https://mermaidjs.github.io/) with language `mermaid`;
-- [WaveDrom](https://wavedrom.com/) for *digital timing diagram* with language `wavedrom`;
-
-For example,
-
-    ```flowchart
-    st=>start: Start:>http://www.google.com[blank]
-    e=>end:>http://www.google.com
-    op1=>operation: My Operation
-    sub1=>subroutine: My Subroutine
-    cond=>condition: Yes
-    or No?:>http://www.google.com
-    io=>inputoutput: catch something...
-
-    st->op1->cond
-    cond(yes)->io->e
-    cond(no)->sub1(right)->op1
-    ```
-
-#### UML
-
-> You need to enable PlantUML in the settings. Pay attention to the privacy issue if you use online PlantUML server. You may need to prepare Java runtime, PlantUML, and Graphviz if you choose local PlantUML.
-
-VNote supports [PlantUML](http://plantuml.com/) to draw UML diagrams. You should use `puml` specified as the language of the fenced code block and write the definition of your diagram within it.
-
-    ```puml
-    @startuml
-    Bob -> Alice : hello
-    @enduml
-    ```
-
-#### Graphviz
-
-> You need to enable Graphviz in the settings.
-
-VNote supports [Graphviz](http://www.graphviz.org/) to draw diagrams. You should use `dot` specified as the language of the fenced code block and write the definition of your diagram within it.
-
-### Math Formulas
-
-> You need to enable MathJax in the `Markdown` menu and restart VNote.
-
-VNote supports math formulas via [MathJax](https://www.mathjax.org/). The default math delimiters are `$$...$$` for **displayed mathematics**, and `$...$` for **inline mathematics**.
-
-- Inline mathematics should not cross multiple lines;
-- Forms like `3$abc$`, `$abc$4`, `$ abc$`, and `$abc $` will not be treated as mathematics;
-- Use `\` to escape `$`;
-- There should be only space chars before opening `$$` and after closing `$$`;
-
-VNote also supports displayed mathematics via fenced code block with language `mathjax` specified.
-
-    ```mathjax
-    $$
-    J(\theta) = \frac 1 2 \sum_{i=1}^m (h_\theta(x^{(i)})-y^{(i)})^2
-    $$
-    ```
-
-Equation number of displayed mathematics is supported:
-
-    $$vnote x markdown = awesome$$ (1.2.1)
-
-### Inline Code
-```md
-Here is a `inline code`.
-```
-
-To insert one `` ` ``, you need to use two `` ` `` to enclose it, such as ``` `` ` `` ```. To insert two `` ` ``, you need to use three `` ` ``.
-
-### Strikethrough
-```md
-Here is a ~~text~~ with strikethrough.
-```
-
-**Notes**:
-
-- VNote provides shortcuts `Ctrl+D` to insert text with strikethrough;
-
-### Task Lists
-```md
-- [x] this is a complete item.
-- [ ] this is an incomplete item.
-```
-
-### Footnote
-```md
-This is a footnote [^1].
-
-[^1]: Here is the detail of the footnote.
-```
-
-### Superscript and Subscript
-
-> You need to enable Superscript or Subscript in the `Markdown` menu and use `Markdown-it` renderer.
-
-```md
-This is the 1^st^ superscript.
-
-This is the H~2~O subscript.
-```
-
-### Alert
-With `Markdown-it` renderer, you can add some alert text.
-
-```md
-::: alert-info
-
-This is an info text.
-
-:::
-
-::: alert-danger
-
-This is a danger text.
-
-:::
-```
-
-Available variants:
-
-```
-alert-primary
-alert-secondary
-alert-success
-alert-info
-alert-warning
-alert-danger
-alert-light
-alert-dark
-```
-
-### New Line and Paragraph
-If you want to enter a new line, you should add two spaces after current line and then continue your input. VNote provides `Shift+Enter` to help.
-
-If you want to enter a new paragraph, you should add an empty line and then continue entering the new paragraph.
-
-Generally, you need to add an empty line after a block element (such as code block, lists, blockquote) to explicitly end it.

-
-For example, the default configruation may look like this:
-
-```ini
-[shortcuts]
-; Define shortcuts here, with each item in the form "operation=keysequence".
-; Leave keysequence empty to disable the shortcut of an operation.
-; Customized shortcuts may conflict with some key bindings in edit mode or Vim mode.
-; Ctrl+Q is reserved for quitting VNote.
-
-; Leader key of Captain mode
-CaptainMode=Ctrl+E
-; Create a note in current folder
-NewNote=Ctrl+Alt+N
-; Save current note
-SaveNote=Ctrl+S
-; Close current note
-CloseNote=
-; Open file/replace dialog
-Find=Ctrl+F
-; Find next occurence
-FindNext=F3
-; Find previous occurence
-FindPrevious=Shift+F3
-

-2. Editor. VNote provides the explorer for local file system to open external files to edit.
-
-Steps to troubleshoot:
-
-1. Go through the context menu, menu bar, tool bar, settings, and help menu to check if you miss something;
-2. Changes to configuration may need re-opening current tabs or restarting VNote;
-3. There is a Markdown guide and shortcuts guide in the help menu, which might be helpful;
-4. Do a quick search in [GitHub Issues](https://github.com/tamlok/vnote/issues) and VNote's [Documentation](https://tamlok.github.io/vnote/en_us/#!docs/_vnote.json);
-5. Post an issue *in detail* on GitHub to ask for help.
-
-Now, how about pressing `Ctrl+G` and start today's work from **Universal Entry**?
-
-Have fun!

-# Markdownガイド
-これは、軽量で使いやすい構文であるMarkdownのためのクイックガイド[^1]です。
-
-## Markdownとは何ですか?
-Mark downは、いくつかの単純なマーカー文字を使ってテキストをスタイル設定する方法です。文書をプレーンテキストで書くことができ、それを美しい表示で読むことができます。
-
-標準的なMarkdown構文は存在せず、多くのエディタは独自の構文を追加することになります。VNoteは、広く使用されている基本構文のみをサポートしています。
-
-## Markdownの使い方。
-Markdownを初めて使用する場合は、構文要素をステップごとに学習しておくことをお勧めします。ヘッダーと強調を知ることは、あなたが生き残るのに十分です。毎日ひとつ、別の新しい構文を学び、それを実践することができます。
-
-## 構文ガイド
-ここでは、VNoteによってサポートされるMarkdown構文の概要を示します。
-
-### ヘッダー
-```md
-#これは<h1>タグです。 
-##これは<h2>タグです。 
-#####これは、<h6>タグです。
-```
-
-**注意事項**:
-
-- `#`の後には、少なくとも1つのスペースが必要です;
-- ヘッダーは1行全体を占める必要があります。
-
-### 強調
-```md
-*このテキストは斜体です* 
-_このテキストはイタリックになります_
-
- **このテキストは太字で表示されます**
- __このテキストは太字になります__
-```
-
-**注意事項**:
-
-- `*`がVNoteでは推奨されます;
-- レンダリングが失敗した場合は、最初の`*`の前と最後の`*`の後に追加スペースを追加してみてください。囲まれたテキストが完全な幅の句読点で始まるか、終了する場合は、スペースが必要です。
-- VNoteは、`Ctrl+I`および`Ctrl+B`による斜体と太字のテキスト挿入ショートカットを提供しています。
-
-### 箇条書き
-#### 順序なしリスト
-```md
-* 項目1  
-これは、箇条書きの項目の1つ目です。ここで、項目のあとに二つの空白文字を挿入していることに注意してください。
-* 項目 2  
-    * 項目 2a
-    * 項目 2b
-* 項目 3
-
-箇条書きの最後には、上記のような空行が必要です。
-```
-
-#### 番号ありリスト
-```md
-1. 項目 1
-1. 項目 2  
-ここで、シーケンス番号が関係していないことに注意してください。Markdownは、レンダリング時に自動的にシーケンス番号を付番します。
-3. 項目 3
-    1. 項目 3a
-    2. 項目 3b
-4. 項目 4
-```
-
-### 表
-```md
-| col 1 | col 2 | col 3 |
-| --- | --- | --- |
-| cell1 | cell2 | cell3 |
-| cell4 | cell5 | cell6 |
-```
-
-### 画像とリンク
-```md
-![Image Alt Text](/url/to/image.png "Optional Text")
-
-![Image Alt Text](/url/to/image.png "Image specified with width and height" =800x600)
-
-![Image Alt Text](/url/to/image.png =800x600)
-
-![Image Alt Text](/url/to/image.png "Image specified with width" =800x)
-
-![Image Alt Text](/url/to/image.png "Image specified with height" =x600)
-
-[Link Text](/url/of/the/link)
-```
-
-**注意事項**:
-
-- リファレンスフォーマットでは、イメージリンクの使用は推奨されません。VNoteは、これらの画像のプレビューをおこないません。
-- 画像のサイズの指定については、**Markdown-it**レンダリングエンジンでのみ有効です。
-
-### ブロック引用
-```md
-VNoteは次のことを示唆しています：
-
-> VNoteは、過去最強のMarkdownノート作成アプリです。  
-ここで、二つの空白文字が、アプリです。の後に挿入されていることに注意してください。
-```
-
-**注意事項**:
-
-- マーカー`>`の後には、少なくとも1つのスペースが必要です;
-- 最初の行には、`>`を一つのみ追加できます;
-
-### フェンスコードブロック
-    ```lang
-    This is a fenced code block.
-    ```
-    
-    ~~~
-    This is another fenced code block.
-    ~~~
-
-**注意事項**:
-
-- `lang`はコードの言語を指定するオプションです。もし指定されなければ、VNoteはハイライト表示をしません。
-
-### 図
-
-> `Markdown`メニューから、Flowcharts.js か、Mermaidか、WaveDromを有効にする必要があります。
-
-VNoteは、図を描くために次のエンジンをサポートしています。フェンスコードブロックに、特定の言語を指定して、その中に図の定義を記述する必要があります。
-
-- [Flowchart.js](http://flowchart.js.org/) for *flowchart* with language `flow` or `flowchart`;
-- [Mermaid](https://mermaidjs.github.io/) with language `mermaid`;
-- [WaveDrom](https://wavedrom.com/) for *digital timing diagram* with language `wavedrom`;
-
-たとえば
-
-    ```flowchart
-    st=>start: Start:>http://www.google.com[blank]
-    e=>end:>http://www.google.com
-    op1=>operation: My Operation
-    sub1=>subroutine: My Subroutine
-    cond=>condition: Yes
-    or No?:>http://www.google.com
-    io=>inputoutput: catch something...
-    
-    st->op1->cond
-    cond(yes)->io->e
-    cond(no)->sub1(right)->op1
-    ```
-
-#### UML
-
-> 設定では、PlantUMLを有効にする必要があります。オンラインPlantUMLサーバを使用する場合は、プライバシーの問題に注意してください。ローカルPlantUMLを選択する場合は、Javaランタイム、PlantUML、およびGraphvizを準備する必要があります。
-
-VNoteは、[PlantUML](http://plantuml.com/)をサポートしてUML図を描画します。フェンスコードブロックの言語として、`puml`を指定し、そのなかにダイヤグラム定義を書くようにしてください。
-
-    ```puml
-    @startuml
-    Bob -> Alice : hello
-    @enduml
-    ```
-
-#### Graphviz
-
-> 設定でGraphvizを有効にする必要があります。
-
-VNoteは、図を描くために[Graphviz](http://www.graphviz.org/)をサポートしています。フェンスコードブロックの言語として、`dot`を指定し、そのなかにダイヤグラム定義を書くようにしてください。
-
-### 数式
-
-> `Markdown`メニューでMathJaxを有効にし、VNoteを再起動する必要があります。
-
-VNoteは、[MathJax](https://www.mathjax.org/)により数式をサポートしています。既定の数式区切りは、**独立数式表示**は`$$...$$`で、**インライン数式表示**は`$...$`です。
-
-- インライン数式は複数行にまたがることはできません。
-- `3$abc$`や`$abc$4`、`$ abc$`、`$abc $`のような文字列は、数式としては扱われません。
-- `$`文字をエスケープするには、`\`を用いてください。
-- 数式開始の`$$`の前や、数式後の`$$`のあとには、空白文字のみ置くことができます。
-
-VNoteは、`mathjax`が指定された言語のフェンスコードブロックを通じて、独立数式をサポートすることができます。
-
-    ```mathjax
-    $$
-    J(\theta) = \frac 1 2 \sum_{i=1}^m (h_\theta(x^{(i)})-y^{(i)})^2
-    $$
-    ```
-
-独立数式表示では、数式番号がサポートされています:
-
-    $$vnote x markdown = awesome$$ (1.2.1)
-
-### インラインコード
-```md
-これは、`インラインコード`です。
-```
-
-`````を一つ入力するには、`````を二つ入力した文字でかこむ必要があります。たとえば````` ` `````となります。ふたつ`````を入力するには、`````が3つ必要です。
-
-### 取り消し線
-```md
-ここでは~~テキスト~~を取り消し線付きで示しています。
-```
-
-**注意事項**:
-
-- VNoteでは、取消線つき文字列を挿入するために、`Ctrl+D`のショートカットを用意しています。
-
-### タスク・リスト
-```md
-- [x] これは完了したアイテムです。
-- [ ] これは未完了のアイテムです。
-```
-
-### 脚注
-```md
-これは脚注[^1]です。
-
-[^1]:これは脚注の詳細です。
-```
-
-### 上付き文字と下付き文字
-
-> `Markdown`メニューで、上付き文字または下付き文字を有効にし、`Markdown-it`レンダラーを使用する必要があります。
-
-```md
-これは、1^st^の上付き文字です。
-
-これは、H~2~O下付き文字です。
-```
-
-### アラート
-`Markdown-it`レンダラを使用すると、警告テキストを追加することができます。
-
-```md
-::: alert-info
-
-This is an info text.
-
-:::
-
-::: alert-danger
-
-This is a danger text.
-
-:::
-```
-
-使用可能なバリアント:
-
-```
-alert-primary
-alert-secondary
-alert-success
-alert-info
-alert-warning
-alert-danger
-alert-light
-alert-dark
-```
-
-### 改行と段落
-新しい行を入力する場合は、現在の行に2つのスペースを追加してから、入力を続行します。VNoteは、その支援のために`Shift+Enter`を提供します。
-
-新しい段落を入力する場合は、空行を追加してから、新しい段落の入力を続ける必要があります。
-
-一般的に、ブロック要素(コードブロック、リスト、ブロッククォートなど)の後に空の行を追加して、明示的に終了する必要があります。

-# Markdown指南
-Markdown是一种轻量级的易用的书写语法。本文是Markdown的一个快速指南[^1]。
-
-## 什么是Markdown？
-Markdown是一种通过少量简单的标记字符来格式化文本的方法。您可以用纯文本来书写文档，然后在阅读时呈现一个美观的排版。
-
-其实并没有一个标准的Markdown语法，很多编辑器都会添加自己的扩展语法。不同于此，为了兼容性，VNote仅仅支持那些被广泛使用的基本语法。
-
-## 如何上手Markdown？
-如果您是刚接触Markdown，那么比较好的一个方法是逐个学习Markdown语法。刚开始，懂得标题和强调语法就能够写出基本的文档；然后，每天可以学习一个新的语法并不断练习。
-
-
-## 语法指南
-下面是VNote支持的Markdown语法的一个概览。
-
-### 标题
-```md
-# This is an <h1> tag
-## This is an <h2> tag
-###### This is an <h6> tag
-```
-
-**注意**：
-
-- `#`之后需要至少一个空格；
-- 一个标题应该占一整行；
-
-### 强调
-```md
-*This text will be italic*  
-_This text will be italic_  
-
-**This text will be bold**  
-__This text will be bold__
-```
-
-**注意**：
-
-- VNote推荐使用`*`；
-- 如果渲染错误，请尝试在第一个`*`之前以及最后一个`*`之后添加一个空格。如果被标记的文本是以全角符号开始或结尾，一般都需要前后添加一个空格；
-- VNote提供快捷键`Ctrl+I`和`Ctrl+B`来插入斜体和粗体；
-
-### 列表
-#### 无序列表
-```md
-* Item 1  
-只是一段在Item 1下面的文字。需要注意上面一行结尾有两个空格。
-* Item 2
-    * Item 2a
-    * Item 2b
-* Item 3
-
-使用一个空行来来结束一个列表。
-```
-
-#### 有序列表
-```md
-1. Item 1
-1. Item 2  
-注意，列表前面的序号其实是无关紧要的，渲染时Markdown会自动修改该序号。
-3. Item 3
-    1. Item 3a
-    2. Item 3b
-4. Item 4
-```
-
-### 表格
-```md
-| col 1 | col 2 | col 3 |
-| --- | --- | --- |
-| cell1 | cell2 | cell3 |
-| cell4 | cell5 | cell6 |
-```
-
-### 图片和链接
-```md
-![Image Alt Text](/url/to/image.png "Optional Text")
-
-![Image Alt Text](/url/to/image.png "Image specified with width and height" =800x600)
-
-![Image Alt Text](/url/to/image.png =800x600)
-
-![Image Alt Text](/url/to/image.png "Image specified with width" =800x)
-
-![Image Alt Text](/url/to/image.png "Image specified with height" =x600)
-
-[Link Text](/url/of/the/link)
-```
-
-**注意**：
-
-- VNote不推荐使用参考式的图片链接。VNote不会预览这些图片。
-- 声明图片尺寸只在 **markdown-it** 中支持。
-
-### 块引用
-```md
-As VNote suggests:
-
-> VNote is the best Markdown note-taking application
-> ever.  
->
-> THere is two spaces after `ever.` above to insert a
-> new line.
-```
-
-**注意**：
-
-- `>`标记后面需要至少一个空格；
-- 多行连续的引用可以只在第一行添加标记；
-
-### 代码块
-    ```lang
-    This is a fenced code block.
-    ```
-
-    ~~~
-    This is another fenced code block.
-    ~~~
-
-**注意**：
-
-- `lang`用于指定代码块的代码语言，可选；如果不指定，VNote不会尝试高亮代码；
-
-### 图表
-
-> 需要在`Markdown`菜单中启用Flowchart.js或Mermaid或WaveDrom，并重新打开当前标签页。
-
-VNote支持使用以下引擎来绘制图表。您需要使用代码块，并标明特定语言，然后在代码块里面定义图表。
-
-- [Flowchart.js](http://flowchart.js.org/)，语言为`flow`或`flowchart`；
-- [Mermaid](https://mermaidjs.github.io/)，语言为`mermaid`；
-- [WaveDrom](https://wavedrom.com/)，数字时序图，语言为`wavedrom`；
-
-例如，
-
-    ```flowchart
-    st=>start: Start:>http://www.google.com[blank]
-    e=>end:>http://www.google.com
-    op1=>operation: My Operation
-    sub1=>subroutine: My Subroutine
-    cond=>condition: Yes
-    or No?:>http://www.google.com
-    io=>inputoutput: catch something...
-
-    st->op1->cond
-    cond(yes)->io->e
-    cond(no)->sub1(right)->op1
-    ```
-
-#### UML
-
-> 需要在设置中启用PlantUML。如果使用在线的PlantUML服务器，请注意隐私问题；如果使用本地PlantUML，可能需要安装Java运行时、PlantUML以及Graphviz。
-
-VNote支持 [PlantUML](http://plantuml.com/) 来实现UML图表。您需要使用代码块，并标明语言为`puml`，然后在代码块里面定义图表。
-
-    ```puml
-    @startuml
-    Bob -> Alice : hello
-    @enduml
-    ```
-
-#### Graphviz
-
-> 需要在设置中启用Graphviz。
-
-VNote支持 [Graphviz](http://www.graphviz.org/) 来绘制图表。您需要使用代码块，并标明语言为`dot`，然后在代码块里面定义图表。
-
-### 数学公式
-
-> 需要在`Markdown`菜单中启用MathJax，并重启VNote。
-
-VNote通过 [MathJax](https://www.mathjax.org/) 来支持数学公式。默认的**块公式**的分隔符是`$$...$$`，**行内公式**的分隔符是`$...$`。
-
-- 行内公式不能跨多行；
-- 形如`3$abc$`/`$abc$4`/`$ abc$`和`$abc $`的不会被解析为公式；
-- 使用`\`转义`$`；
-- 开始的`$$`之前以及结束的`$$`之后都只允许出现空格字符；
-
-VNote也可以使用标明语言`mathjax`的代码块来实现块公式。
-
-    ```mathjax
-    $$
-    J(\theta) = \frac 1 2 \sum_{i=1}^m (h_\theta(x^{(i)})-y^{(i)})^2
-    $$
-    ```
-
-块公式支持公式序号：
-
-    $$vnote x markdown = awesome$$ (1.2.1)
-
-### 行内代码
-```md
-Here is a `inline code`.
-```
-
-如果想输入一个 `` ` ``，需要使用两个 `` ` `` 来括住它，例如 ``` `` ` `` ```。 要输入两个 `` ` ``，则需要使用三个 `` ` ``。
-
-### 删除线
-```md
-Here is a ~~text~~ with strikethrough.
-```
-
-**注意**：
-
-- VNote提供快捷键`Ctrl+D`来插入带有删除线的文本；
-
-### 任务列表
-```md
-- [x] this is a complete item.
-- [ ] this is an incomplete item.
-```
-
-### 脚注
-```md
-This is a footnote [^1].
-
-[^1]: Here is the detail of the footnote.
-```
-
-### 上标和下标
-
-> 需要在`Markdown`菜单中启用上标和下标并使用`Markdown-it`渲染引擎。
-
-```md
-This is the 1^st^ superscript.
-
-This is the H~2~O subscript.
-```
-
-### 警告
-使用`Markdown-it`渲染引擎时，可以添加警告信息。
-
-```md
-::: alert-info
-
-这是一个信息文本。
-
-:::
-
-::: alert-danger
-
-这是一个危险文本。
-
-:::
-```
-
-可用的一些警告形式如下：
-
-```
-alert-primary
-alert-secondary
-alert-success
-alert-info
-alert-warning
-alert-danger
-alert-light
-alert-dark
-```
-
-### 换行和段落
-如果需要换行，您应该在当前行末尾添加两个空格，然后换行。VNote提供快捷键`Shift+Enter`来辅助用户输入两个空格并换行。
-
-如果需要一个新的段落，您应该先插入一个空行然后才输入新的段落的文本。
-
-一般来说，您应该在一个块元素（例如代码块、列表和块引用）后面插入一个空行来显式结束该元素。
-

-## Version 9.0.0
-
-The new major version brings a reworked styling system. Highlight.js now defines
-a limited set of highlightable classes giving a consistent result across all the
-styles and languages. You can read a more detailed explanation and background in
-the [tracking issue][#348] that started this long process back in May.
-
-This change is backwards incompatible for those who uses highlight.js with a
-custom stylesheet. The [new style guide][sg] explains how to write styles
-in this new world.
-
-Bundled themes have also suffered a significant amount of improvements and may
-look different in places, but all the things now consistent and make more sense.
-Among others, the Default style has got a refresh and will probably be tweaked
-some more in next releases. Please do give your feedback in our
-[issue tracker][issues].
-
-New languages in this release:
-
-- *Caché Object Script* by [Nikita Savchenko][]
-- *YAML* by [Stefan Wienert][]
-- *MIPS Assembler* by [Nebuleon Fumika][]
-- *HSP* by [prince][]
-
-Improvements to existing languages and styles:
-

-## Version 8.4
-
-We've got the new [demo page][]! The obvious new feature is the new look, but
-apart from that it's got smarter: by presenting languages in groups it avoids
-running 10000 highlighting attempts after first load which was slowing it down
-and giving bad overall impression. It is now also being generated from test
-code snippets so the authors of new languages don't have to update both tests
-and the demo page with the same thing.
-
-Other notable changes:
-
-- The `template_comment` class is gone in favor of the more general `comment`.
-- Number parsing unified and improved across languages.
-- C++, Java and C# now use unified grammar to highlight titles in
-  function/method definitions.
-- The browser build is now usable as an AMD module, there's no separate build
-  target for that anymore.
-- OCaml has got a [comprehensive overhaul][ocaml] by [Mickaël Delahaye][].
-- Clojure's data structures and literals are now highlighted outside of lists
-  and we can now highlight Clojure's REPL sessions.
-
-New languages:
-
-- *AspectJ* by [Hakan Özler][]
-- *STEP Part 21* by [Adam Joseph Cook][]
-- *SML* derived by [Edwin Dalorzo][] from OCaml definition
-- *Mercury* by [mucaho][]
-- *Smali* by [Dennis Titze][]
-- *Verilog* by [Jon Evans][]

-
-## Version 8.3
-
-We streamlined our tool chain, it is now based entirely on node.js instead of
-being a mix of node.js, Python and Java. The build script options and arguments
-remained the same, and we've noted all the changes in the [documentation][b].
-Apart from reducing complexity, the new build script is also faster from not
-having to start Java machine repeatedly. The credits for the work go to [Jeremy
-Hull][].
-
-Some notable fixes:
-
-- PHP and JavaScript mixed in HTML now live happily with each other.
-- JavaScript regexes now understand ES6 flags "u" and "y".
-- `throw` keyword is no longer detected as a method name in Java.
-- Fixed parsing of numbers and symbols in Clojure thanks to [input from Ivan
-  Kleshnin][ik].
-
-New languages in this release:
-
-- *Less* by [Max Mikhailov][]
-- *Stylus* by [Bryant Williams][]
-- *Tcl* by [Radek Liska][]
-- *Puppet* by [Jose Molina Colmenero][]
-- *Processing* by [Erik Paluka][]

-## Version 8.2
-
-We've finally got [real tests][test] and [continuous testing on Travis][ci]
-thanks to [Jeremy Hull][] and [Chris Eidhof][]. The tests designed to cover
-everything: language detection, correct parsing of individual language features
-and various special cases. This is a very important change that gives us
-confidence in extending language definitions and refactoring library core.
-
-We're going to redesign the old [demo/test suite][demo] into an interactive
-demo web app. If you're confident front-end developer or designer and want to
-help us with it, drop a comment into [the issue][#542] on GitHub.

-## Version 8.0
-
-This new major release is quite a big overhaul bringing both new features and
-some backwards incompatible changes. However, chances are that the majority of
-users won't be affected by the latter: the basic scenario described in the
-README is left intact.
-
-Here's what did change in an incompatible way:
-
-- We're now prefixing all classes located in [CSS classes reference][cr] with
-  `hljs-`, by default, because some class names would collide with other
-  people's stylesheets. If you were using an older version, you might still want
-  the previous behavior, but still want to upgrade. To suppress this new
-  behavior, you would initialize like so:
-
-  ```html
-  <script type="text/javascript">
-    hljs.configure({classPrefix: ''});
-    hljs.initHighlightingOnLoad();
-  </script>
-  ```
-
-- `tabReplace` and `useBR` that were used in different places are also unified
-  into the global options object and are to be set using `configure(options)`.
-  This function is documented in our [API docs][]. Also note that these
-  parameters are gone from `highlightBlock` and `fixMarkup` which are now also
-  rely on `configure`.
-
-- We removed public-facing (though undocumented) object `hljs.LANGUAGES` which
-  was used to register languages with the library in favor of two new methods:
-  `registerLanguage` and `getLanguage`. Both are documented in our [API docs][].
-
-- Result returned from `highlight` and `highlightAuto` no longer contains two
-  separate attributes contributing to relevance score, `relevance` and
-  `keyword_count`. They are now unified in `relevance`.
-
-Another technically compatible change that nonetheless might need attention:
-
-- The structure of the NPM package was refactored, so if you had installed it
-  locally, you'll have to update your paths. The usual `require('highlight.js')`
-  works as before. This is contributed by [Dmitry Smolin][].
-
-New features:
-
-- Languages now can be recognized by multiple names like "js" for JavaScript or
-  "html" for, well, HTML (which earlier insisted on calling it "xml"). These
-  aliases can be specified in the class attribute of the code container in your
-  HTML as well as in various API calls. For now there are only a few very common
-  aliases but we'll expand it in the future. All of them are listed in the
-  [class reference][cr].
-
-- Language detection can now be restricted to a subset of languages relevant in
-  a given context — a web page or even a single highlighting call. This is
-  especially useful for node.js build that includes all the known languages.
-  Another example is a StackOverflow-style site where users specify languages
-  as tags rather than in the markdown-formatted code snippets. This is
-  documented in the [API reference][] (see methods `highlightAuto` and
-  `configure`).
-
-- Language definition syntax streamlined with [variants][] and
-  [beginKeywords][].
-
-New languages and styles:
-
-- *Oxygene* by [Carlo Kok][]
-- *Mathematica* by [Daniel Kvasnička][]
-- *Autohotkey* by [Seongwon Lee][]
-- *Atelier* family of styles in 10 variants by [Bram de Haan][]
-- *Paraíso* styles by [Jan T. Sott][]
-
-Miscellaneous improvements:
-
-- Highlighting `=>` prompts in Clojure.
-- [Jeremy Hull][] fixed a lot of styles for consistency.
-- Finally, highlighting PHP and HTML [mixed in peculiar ways][php-html].
-- Objective C and C# now properly highlight titles in method definition.
-- Big overhaul of relevance counting for a number of languages. Please do report
-  bugs about mis-detection of non-trivial code snippets!

-## Version 7.5
-
-A catch-up release dealing with some of the accumulated contributions. This one
-is probably will be the last before the 8.0 which will be slightly backwards
-incompatible regarding some advanced use-cases.
-
-One outstanding change in this version is the addition of 6 languages to the
-[hosted script][d]: Markdown, ObjectiveC, CoffeeScript, Apache, Nginx and
-Makefile. It now weighs about 6K more but we're going to keep it under 30K.
-
-New languages:
-
-- OCaml by [Mehdi Dogguy][mehdid] and [Nicolas Braud-Santoni][nbraud]
-- [LiveCode Server][lcs] by [Ralf Bitter][revig]
-- Scilab by [Sylvestre Ledru][sylvestre]
-- basic support for Makefile by [Ivan Sagalaev][isagalaev]
-
-Improvements:
-
-- Ruby's got support for characters like `?A`, `?1`, `?\012` etc. and `%r{..}`
-  regexps.
-- Clojure now allows a function call in the beginning of s-expressions
-  `(($filter "myCount") (arr 1 2 3 4 5))`.
-- Haskell's got new keywords and now recognizes more things like pragmas,
-  preprocessors, modules, containers, FFIs etc. Thanks to [Zena Treep][treep]
-  for the implementation and to [Jeremy Hull][sourrust] for guiding it.
-- Miscellaneous fixes in PHP, Brainfuck, SCSS, Asciidoc, CMake, Python and F#.

-## New core developers
-
-The latest long period of almost complete inactivity in the project coincided
-with growing interest to it led to a decision that now seems completely obvious:
-we need more core developers.
-
-So without further ado let me welcome to the core team two long-time
-contributors: [Jeremy Hull][] and [Oleg
-Efimov][].
-
-Hope now we'll be able to work through stuff faster!
-
-P.S. The historical commit is [here][1] for the record.

-## Version 7.3
-
-- Since this version highlight.js no longer works in IE version 8 and older.
-  It's made it possible to reduce the library size and dramatically improve code
-  readability and made it easier to maintain. Time to go forward!
-
-- New languages: AppleScript (by [Nathan Grigg][ng] and [Dr. Drang][dd]) and
-  Brainfuck (by [Evgeny Stepanischev][bolk]).
-
-- Improvements to existing languages:
-
-    - interpreter prompt in Python (`>>>` and `...`)
-    - @-properties and classes in CoffeeScript
-    - E4X in JavaScript (by [Oleg Efimov][oe])
-    - new keywords in Perl (by [Kirk Kimmel][kk])
-    - big Ruby syntax update (by [Vasily Polovnyov][vast])
-    - small fixes in Bash
-
-- Also Oleg Efimov did a great job of moving all the docs for language and style
-  developers and contributors from the old wiki under the source code in the
-  "docs" directory. Now these docs are nicely presented at
-  <http://highlightjs.readthedocs.org/>.

-
-## Version 7.2
-
-A regular bug-fix release without any significant new features. Enjoy!
-
-
-## Version 7.1
-
-A Summer crop:
-
-- [Marc Fornos][mf] made the definition for Clojure along with the matching
-  style Rainbow (which, of course, works for other languages too).
-- CoffeeScript support continues to improve getting support for regular
-  expressions.
-- Yoshihide Jimbo ported to highlight.js [five Tomorrow styles][tm] from the
-  [project by Chris Kempson][tm0].
-- Thanks to [Casey Duncun][cd] the library can now be built in the popular
-  [AMD format][amd].
-- And last but not least, we've got a fair number of correctness and consistency
-  fixes, including a pretty significant refactoring of Ruby.

-
-## Version 7.0
-
-The reason for the new major version update is a global change of keyword syntax
-which resulted in the library getting smaller once again. For example, the
-hosted build is 2K less than at the previous version while supporting two new
-languages.
-
-Notable changes:
-
-- The library now works not only in a browser but also with [node.js][]. It is
-  installable with `npm install highlight.js`. [API][] docs are available on our
-  wiki.
-
-- The new unique feature (apparently) among syntax highlighters is highlighting
-  *HTTP* headers and an arbitrary language in the request body. The most useful
-  languages here are *XML* and *JSON* both of which highlight.js does support.
-  Here's [the detailed post][p] about the feature.
-
-- Two new style themes: a dark "south" *[Pojoaque][]* by Jason Tate and an
-  emulation of*XCode* IDE by [Angel Olloqui][ao].
-
-- Three new languages: *D* by [Aleksandar Ružičić][ar], *R* by [Joe Cheng][jc]
-  and *GLSL* by [Sergey Tikhomirov][st].
-
-- *Nginx* syntax has become a million times smaller and more universal thanks to
-  remaking it in a more generic manner that doesn't require listing all the
-  directives in the known universe.
-
-- Function titles are now highlighted in *PHP*.
-
-- *Haskell* and *VHDL* were significantly reworked to be more rich and correct
-  by their respective maintainers [Jeremy Hull][sr] and [Igor Kalnitsky][ik].
-
-And last but not least, many bugs have been fixed around correctness and
-language detection.
-
-Overall highlight.js currently supports 51 languages and 20 style themes.

-## Version 6.2
-
-A lot of things happened in highlight.js since the last version! We've got nine
-new contributors, the discussion group came alive, and the main branch on GitHub
-now counts more than 350 followers. Here are most significant results coming
-from all this activity:
-
-- 5 (five!) new languages: Rust, ActionScript, CoffeeScript, MatLab and
-  experimental support for markdown. Thanks go to [Andrey Vlasovskikh][av],
-  [Alexander Myadzel][am], [Dmytrii Nagirniak][dn], [Oleg Efimov][oe], [Denis
-  Bardadym][db] and [John Crepezzi][jc].
-
-- 2 new style themes: Monokai by [Luigi Maselli][lm] and stylistic imitation of
-  another well-known highlighter Google Code Prettify by [Aahan Krish][ak].
-
-- A vast number of [correctness fixes and code refactorings][log], mostly made
-  by [Oleg Efimov][oe] and [Evgeny Stepanischev][es].

-
-## Version 6.1 — Solarized
-
-[Jeremy Hull][jh] has implemented my dream feature — a port of [Solarized][]
-style theme famous for being based on the intricate color theory to achieve
-correct contrast and color perception. It is now available for highlight.js in
-both variants — light and dark.
-
-This version also adds a new original style Arta. Its author pumbur maintains a
-[heavily modified fork of highlight.js][pb] on GitHub.
-
-[jh]: https://github.com/sourrust
-[solarized]: http://ethanschoonover.com/solarized
-[pb]: https://github.com/pumbur/highlight.js
-
-
-## Version 6.0
-
-New major version of the highlighter has been built on a significantly
-refactored syntax. Due to this it's even smaller than the previous one while
-supporting more languages!
-
-New languages are:
-
-- Haskell by [Jeremy Hull][sourrust]
-- Erlang in two varieties — module and REPL — made collectively by [Nikolay
-  Zakharov][desh], [Dmitry Kovega][arhibot] and [Sergey Ignatov][ignatov]
-- Objective C by [Valerii Hiora][vhbit]
-- Vala by [Antono Vasiljev][antono]
-- Go by [Stephan Kountso][steplg]

-[vhbit]: https://github.com/vhbit
-[antono]: https://github.com/antono
-[steplg]: https://github.com/steplg
-
-Also this version is marginally faster and fixes a number of small long-standing
-bugs.
-
-Developer overview of the new language syntax is available in a [blog post about
-recent beta release][beta].
-
-[beta]: http://softwaremaniacs.org/blog/2011/04/25/highlight-js-60-beta/en/
-
-P.S. New version is not yet available on a Yandex CDN, so for now you have to
-download [your own copy][d].
-
-[d]: /soft/highlight/en/download/
-
-
-## Version 5.14
-
-Fixed bugs in HTML/XML detection and relevance introduced in previous
-refactoring.
-
-Also test.html now shows the second best result of language detection by
-relevance.
-
-
-## Version 5.13
-
-Past weekend began with a couple of simple additions for existing languages but
-ended up in a big code refactoring bringing along nice improvements for language
-developers.
-
-### For users
-
-- Description of C++ has got new keywords from the upcoming [C++ 0x][] standard.
-- Description of HTML has got new tags from [HTML 5][].
-- CSS-styles have been unified to use consistent padding and also have lost
-  pop-outs with names of detected languages.
-- [Igor Kalnitsky][ik] has sent two new language descriptions: CMake & VHDL.
-
-This makes total number of languages supported by highlight.js to reach 35.
-
-Bug fixes:
-
-- Custom classes on `<pre>` tags are not being overridden anymore
-- More correct highlighting of code blocks inside non-`<pre>` containers:
-  highlighter now doesn't insist on replacing them with its own container and
-  just replaces the contents.
-- Small fixes in browser compatibility and heuristics.
-
-[c++ 0x]: http://ru.wikipedia.org/wiki/C%2B%2B0x
-[html 5]: http://en.wikipedia.org/wiki/HTML5
-[ik]: http://kalnitsky.org.ua/
-
-### For developers
-
-The most significant change is the ability to include language submodes right
-under `contains` instead of defining explicit named submodes in the main array:
-
-    contains: [
-      'string',
-      'number',
-      {begin: '\\n', end: hljs.IMMEDIATE_RE}
-    ]
-
-This is useful for auxiliary modes needed only in one place to define parsing.
-Note that such modes often don't have `className` and hence won't generate a
-separate `<span>` in the resulting markup. This is similar in effect to
-`noMarkup: true`. All existing languages have been refactored accordingly.
-
-Test file test.html has at last become a real test. Now it not only puts the
-detected language name under the code snippet but also tests if it matches the
-expected one. Test summary is displayed right above all language snippets.
-
-
-## CDN
-
-Fine people at [Yandex][] agreed to host highlight.js on their big fast servers.
-[Link up][l]!

-
-
-## Version 5.10 — "Paris".
-
-Though I'm on a vacation in Paris, I decided to release a new version with a
-couple of small fixes:
-
-- Tomas Vitvar discovered that TAB replacement doesn't always work when used
-  with custom markup in code
-- SQL parsing is even more rigid now and doesn't step over SmallTalk in tests
-
-
-## Version 5.9
-
-A long-awaited version is finally released.
-
-New languages:
-
-- Andrew Fedorov made a definition for Lua
-- a long-time highlight.js contributor [Peter Leonov][pl] made a definition for
-  Nginx config
-- [Vladimir Moskva][vm] made a definition for TeX
-
-[pl]: http://kung-fu-tzu.ru/
-[vm]: http://fulc.ru/
-
-Fixes for existing languages:
-
-- [Loren Segal][ls] reworked the Ruby definition and added highlighting for
-  [YARD][] inline documentation
-- the definition of SQL has become more solid and now it shouldn't be overly
-  greedy when it comes to language detection
-
-[ls]: http://gnuu.org/
-[yard]: http://yardoc.org/
-
-The highlighter has become more usable as a library allowing to do highlighting
-from initialization code of JS frameworks and in ajax methods (see.
-readme.eng.txt).
-
-Also this version drops support for the [WordPress][wp] plugin. Everyone is
-welcome to [pick up its maintenance][p] if needed.
-
-[wp]: http://wordpress.org/
-[p]: http://bazaar.launchpad.net/~isagalaev/+junk/highlight/annotate/342/src/wp_highlight.js.php
-
-
-## Version 5.8
-
-- Jan Berkel has contributed a definition for Scala. +1 to hotness!
-- All CSS-styles are rewritten to work only inside `<pre>` tags to avoid
-  conflicts with host site styles.
-
-
-## Version 5.7.
-
-Fixed escaping of quotes in VBScript strings.
-
-
-## Version 5.5
-
-This version brings a small change: now .ini-files allow digits, underscores and
-square brackets in key names.
-
-
-## Version 5.4
-
-Fixed small but upsetting bug in the packer which caused incorrect highlighting
-of explicitly specified languages. Thanks to Andrew Fedorov for precise
-diagnostics!
-
-
-## Version 5.3
-
-The version to fulfil old promises.
-
-The most significant change is that highlight.js now preserves custom user
-markup in code along with its own highlighting markup. This means that now it's
-possible to use, say, links in code. Thanks to [Vladimir Dolzhenko][vd] for the
-[initial proposal][1] and for making a proof-of-concept patch.
-
-Also in this version:
-
-- [Vasily Polovnyov][vp] has sent a GitHub-like style and has implemented
-  support for CSS @-rules and Ruby symbols.
-- Yura Zaripov has sent two styles: Brown Paper and School Book.
-- Oleg Volchkov has sent a definition for [Parser 3][p3].

-
-
-## Version 5.2
-
-- at last it's possible to replace indentation TABs with something sensible
-  (e.g. 2 or 4 spaces)
-- new keywords and built-ins for 1C by Sergey Baranov
-- a couple of small fixes to Apache highlighting
-
-
-## Version 5.1
-
-This is one of those nice version consisting entirely of new and shiny
-contributions!
-
-- [Vladimir Ermakov][vooon] created highlighting for AVR Assembler
-- [Ruslan Keba][rukeba] created highlighting for Apache config file. Also his
-  original visual style for it is now available for all highlight.js languages
-  under the name "Magula".
-- [Shuen-Huei Guan][drake] (aka Drake) sent new keywords for RenderMan
-  languages. Also thanks go to [Konstantin Evdokimenko][ke] for his advice on
-  the matter.

-[ke]: http://k-evdokimenko.moikrug.ru/
-
-
-## Version 5.0
-
-The main change in the new major version of highlight.js is a mechanism for
-packing several languages along with the library itself into a single compressed
-file. Now sites using several languages will load considerably faster because
-the library won't dynamically include additional files while loading.
-
-Also this version fixes a long-standing bug with Javascript highlighting that
-couldn't distinguish between regular expressions and division operations.
-
-And as usually there were a couple of minor correctness fixes.
-
-Great thanks to all contributors! Keep using highlight.js.
-
-
-## Version 4.3
-
-This version comes with two contributions from [Jason Diamond][jd]:
-
-- language definition for C# (yes! it was a long-missed thing!)
-- Visual Studio-like highlighting style
-
-Plus there are a couple of minor bug fixes for parsing HTML and XML attributes.
-
-[jd]: http://jason.diamond.name/weblog/
-
-
-## Version 4.2
-
-The biggest news is highlighting for Lisp, courtesy of Vasily Polovnyov. It's
-somewhat experimental meaning that for highlighting "keywords" it doesn't use
-any pre-defined set of a Lisp dialect. Instead it tries to highlight first word
-in parentheses wherever it makes sense. I'd like to ask people programming in
-Lisp to confirm if it's a good idea and send feedback to [the forum][f].
-
-Other changes:
-
-- Smalltalk was excluded from DEFAULT_LANGUAGES to save traffic
-- [Vladimir Epifanov][voldmar] has implemented javascript style switcher for
-  test.html
-- comments now allowed inside Ruby function definition
-- [MEL][] language from [Shuen-Huei Guan][drake]
-- whitespace now allowed between `<pre>` and `<code>`
-- better auto-detection of C++ and PHP
-- HTML allows embedded VBScript (`<% .. %>`)

-[voldmar]: http://voldmar.ya.ru/
-[mel]: http://en.wikipedia.org/wiki/Maya_Embedded_Language
-[drake]: http://drakeguan.org/
-
-
-## Version 4.1
-
-Languages:
-
-- Bash from Vah
-- DOS bat-files from Alexander Makarov (Sam)
-- Diff files from Vasily Polovnyov
-- Ini files from myself though initial idea was from Sam
-
-Styles:
-
-- Zenburn from Vladimir Epifanov, this is an imitation of a
-  [well-known theme for Vim][zenburn].
-- Ascetic from myself, as a realization of ideals of non-flashy highlighting:
-  just one color in only three gradations :-)
-
-In other news. [One small bug][bug] was fixed, built-in keywords were added for
-Python and C++ which improved auto-detection for the latter (it was shame that
-[my wife's blog][alenacpp] had issues with it from time to time). And lastly
-thanks go to Sam for getting rid of my stylistic comments in code that were
-getting in the way of [JSMin][].

-
-
-## Version 4.0
-
-New major version is a result of vast refactoring and of many contributions.
-
-Visible new features:
-
-- Highlighting of embedded languages. Currently is implemented highlighting of
-  Javascript and CSS inside HTML.
-- Bundled 5 ready-made style themes!
-
-Invisible new features:
-
-- Highlight.js no longer pollutes global namespace. Only one object and one
-  function for backward compatibility.
-- Performance is further increased by about 15%.
-
-Changing of a major version number caused by a new format of language definition
-files. If you use some third-party language files they should be updated.
-
-
-## Version 3.5
-
-A very nice version in my opinion fixing a number of small bugs and slightly
-increased speed in a couple of corner cases. Thanks to everybody who reports
-bugs in he [forum][f] and by email!
-
-There is also a new language — XML. A custom XML formerly was detected as HTML
-and didn't highlight custom tags. In this version I tried to make custom XML to
-be detected and highlighted by its own rules. Which by the way include such
-things as CDATA sections and processing instructions (`<? ... ?>`).
-
-[f]: http://softwaremaniacs.org/forum/viewforum.php?id=6
-
-
-## Version 3.3
-
-[Vladimir Gubarkov][xonix] has provided an interesting and useful addition.
-File export.html contains a little program that shows and allows to copy and
-paste an HTML code generated by the highlighter for any code snippet. This can
-be useful in situations when one can't use the script itself on a site.
-
-
-[xonix]: http://xonixx.blogspot.com/
-
-
-## Version 3.2 consists completely of contributions:
-
-- Vladimir Gubarkov has described SmallTalk
-- Yuri Ivanov has described 1C
-- Peter Leonov has packaged the highlighter as a Firefox extension
-- Vladimir Ermakov has compiled a mod for phpBB
-
-Many thanks to you all!
-
-
-## Version 3.1
-
-Three new languages are available: Django templates, SQL and Axapta. The latter
-two are sent by [Dmitri Roudakov][1]. However I've almost entirely rewrote an
-SQL definition but I'd never started it be it from the ground up :-)
-
-The engine itself has got a long awaited feature of grouping keywords
-("keyword", "built-in function", "literal"). No more hacks!
-
-[1]: http://roudakov.ru/
-
-
-## Version 3.0
-
-It is major mainly because now highlight.js has grown large and has become
-modular. Now when you pass it a list of languages to highlight it will
-dynamically load into a browser only those languages.
-
-Also:
-
-- Konstantin Evdokimenko of [RibKit][] project has created a highlighting for
-  RenderMan Shading Language and RenderMan Interface Bytestream. Yay for more
-  languages!
-- Heuristics for C++ and HTML got better.
-- I've implemented (at last) a correct handling of backslash escapes in C-like
-  languages.
-
-There is also a small backwards incompatible change in the new version. The
-function initHighlighting that was used to initialize highlighting instead of
-initHighlightingOnLoad a long time ago no longer works. If you by chance still
-use it — replace it with the new one.
-
-[RibKit]: http://ribkit.sourceforge.net/
-
-
-## Version 2.9
-
-Highlight.js is a parser, not just a couple of regular expressions. That said
-I'm glad to announce that in the new version 2.9 has support for:
-
-- in-string substitutions for Ruby -- `#{...}`
-- strings from from numeric symbol codes (like #XX) for Delphi
-
-
-## Version 2.8
-
-A maintenance release with more tuned heuristics. Fully backwards compatible.
-
-
-## Version 2.7
-
-- Nikita Ledyaev presents highlighting for VBScript, yay!
-- A couple of bugs with escaping in strings were fixed thanks to Mickle
-- Ongoing tuning of heuristics
-
-Fixed bugs were rather unpleasant so I encourage everyone to upgrade!
-
-
-## Version 2.4
-
-- Peter Leonov provides another improved highlighting for Perl
-- Javascript gets a new kind of keywords — "literals". These are the words
-  "true", "false" and "null"
-
-Also highlight.js homepage now lists sites that use the library. Feel free to
-add your site by [dropping me a message][mail] until I find the time to build a
-submit form.
-
-[mail]: mailto:Maniac@SoftwareManiacs.Org
-
-
-## Version 2.3
-
-This version fixes IE breakage in previous version. My apologies to all who have
-already downloaded that one!
-
-
-## Version 2.2
-
-- added highlighting for Javascript
-- at last fixed parsing of Delphi's escaped apostrophes in strings
-- in Ruby fixed highlighting of keywords 'def' and 'class', same for 'sub' in
-  Perl
-
-
-## Version 2.0
-
-- Ruby support by [Anton Kovalyov][ak]
-- speed increased by orders of magnitude due to new way of parsing
-- this same way allows now correct highlighting of keywords in some tricky
-  places (like keyword "End" at the end of Delphi classes)
-
-[ak]: http://anton.kovalyov.net/
-
-
-## Version 1.0
-
-Version 1.0 of javascript syntax highlighter is released!
-
-It's the first version available with English description. Feel free to post
-your comments and question to [highlight.js forum][forum]. And don't be afraid
-if you find there some fancy Cyrillic letters -- it's for Russian users too :-)

-# Highlight.js
-
-[![Build Status](https://travis-ci.org/isagalaev/highlight.js.svg?branch=master)](https://travis-ci.org/isagalaev/highlight.js)
-
-Highlight.js is a syntax highlighter written in JavaScript. It works in
-the browser as well as on the server. It works with pretty much any
-markup, doesn’t depend on any framework and has automatic language
-detection.
-
-## Getting Started
-
-The bare minimum for using highlight.js on a web page is linking to the
-library along with one of the styles and calling
-[`initHighlightingOnLoad`][1]:
-
-```html
-<link rel="stylesheet" href="/path/to/styles/default.css">
-<script src="/path/to/highlight.pack.js"></script>
-<script>hljs.initHighlightingOnLoad();</script>
-```
-
-This will find and highlight code inside of `<pre><code>` tags; it tries
-to detect the language automatically. If automatic detection doesn’t
-work for you, you can specify the language in the `class` attribute:
-
-```html
-<pre><code class="html">...</code></pre>
-```
-
-The list of supported language classes is available in the [class
-reference][2].  Classes can also be prefixed with either `language-` or
-`lang-`.
-
-To disable highlighting altogether use the `nohighlight` class:
-
-```html
-<pre><code class="nohighlight">...</code></pre>
-```
-
-## Custom Initialization
-
-When you need a bit more control over the initialization of
-highlight.js, you can use the [`highlightBlock`][3] and [`configure`][4]
-functions. This allows you to control *what* to highlight and *when*.
-
-Here’s an equivalent way to calling [`initHighlightingOnLoad`][1] using
-jQuery:
-
-```javascript
-$(document).ready(function() {
-  $('pre code').each(function(i, block) {
-    hljs.highlightBlock(block);
-  });
-});
-```
-
-You can use any tags instead of `<pre><code>` to mark up your code. If
-you don't use a container that preserve line breaks you will need to
-configure highlight.js to use the `<br>` tag:
-
-```javascript
-hljs.configure({useBR: true});
-
-$('div.code').each(function(i, block) {
-  hljs.highlightBlock(block);
-});
-```
-
-For other options refer to the documentation for [`configure`][4].
-
-
-## Web Workers
-
-You can run highlighting inside a web worker to avoid freezing the browser
-window while dealing with very big chunks of code.
-
-In your main script:
-
-```javascript
-addEventListener('load', function() {
-  var code = document.querySelector('#code');
-  var worker = new Worker('worker.js');
-  worker.onmessage = function(event) { code.innerHTML = event.data; }
-  worker.postMessage(code.textContent);
-})
-```
-
-In worker.js:
-
-```javascript
-onmessage = function(event) {
-  importScripts('<path>/highlight.pack.js');
-  var result = self.hljs.highlightAuto(event.data);
-  postMessage(result.value);
-}
-```
-
-
-## Getting the Library
-
-You can get highlight.js as a hosted, or custom-build, browser script or
-as a server module. Right out of the box the browser script supports
-both AMD and CommonJS, so if you wish you can use RequireJS or
-Browserify without having to build from source. The server module also
-works perfectly fine with Browserify, but there is the option to use a
-build specific to browsers rather than something meant for a server.
-Head over to the [download page][5] for all the options.
-
-**Don't link to GitHub directly.** The library is not supposed to work straight
-from the source, it requires building. If none of the pre-packaged options
-work for you refer to the [building documentation][6].
-
-**The CDN-hosted package doesn't have all the languages.** Otherwise it'd be
-too big. If you don't see the language you need in the ["Common" section][5],
-it can be added manually:
-
-```html
-<script src="//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.4.0/languages/go.min.js"></script>
-```
-
-**On Almond.** You need to use the optimizer to give the module a name. For
-example:
-
-```
-r.js -o name=hljs paths.hljs=/path/to/highlight out=highlight.js
-```

-# Highlight.js
-
-Highlight.js — это инструмент для подсветки синтаксиса, написанный на JavaScript. Он работает
-и в браузере, и на сервере. Он работает с практически любой HTML разметкой, не
-зависит от каких-либо фреймворков и умеет автоматически определять язык.
-
-
-## Начало работы
-
-Минимум, что нужно сделать для использования highlight.js на веб-странице — это
-подключить библиотеку, CSS-стили и вызывать [`initHighlightingOnLoad`][1]:
-
-```html
-<link rel="stylesheet" href="/path/to/styles/default.css">
-<script src="/path/to/highlight.pack.js"></script>
-<script>hljs.initHighlightingOnLoad();</script>
-```
-
-Библиотека найдёт и раскрасит код внутри тегов `<pre><code>`, попытавшись
-автоматически определить язык. Когда автоопределение не срабатывает, можно явно
-указать язык в атрибуте class:
-
-```html
-<pre><code class="html">...</code></pre>
-```
-
-Список поддерживаемых классов языков доступен в [справочнике по классам][2].
-Класс также можно предварить префиксами `language-` или `lang-`.
-
-Чтобы отключить подсветку для какого-то блока, используйте класс `nohighlight`:
-
-```html
-<pre><code class="nohighlight">...</code></pre>
-```
-
-## Инициализация вручную
-
-Чтобы иметь чуть больше контроля за инициализацией подсветки, вы можете
-использовать функции [`highlightBlock`][3] и [`configure`][4]. Таким образом
-можно управлять тем, *что* и *когда* подсвечивать.
-
-Вот пример инициализации, эквивалентной вызову [`initHighlightingOnLoad`][1], но
-с использованием jQuery:
-
-```javascript
-$(document).ready(function() {
-  $('pre code').each(function(i, block) {
-    hljs.highlightBlock(block);
-  });
-});
-```
-
-Вы можете использовать любые теги разметки вместо `<pre><code>`. Если
-используете контейнер, не сохраняющий переводы строк, вам нужно сказать
-highlight.js использовать для них тег `<br>`:
-
-```javascript
-hljs.configure({useBR: true});
-
-$('div.code').each(function(i, block) {
-  hljs.highlightBlock(block);
-});
-```
-
-Другие опции можно найти в документации функции [`configure`][4].
-
-
-## Web Workers
-
-Подсветку можно запустить внутри web worker'а, чтобы окно
-браузера не подтормаживало при работе с большими кусками кода.
-
-В основном скрипте:
-
-```javascript
-addEventListener('load', function() {
-  var code = document.querySelector('#code');
-  var worker = new Worker('worker.js');
-  worker.onmessage = function(event) { code.innerHTML = event.data; }
-  worker.postMessage(code.textContent);
-})
-```
-
-В worker.js:
-
-```javascript
-onmessage = function(event) {
-  importScripts('<path>/highlight.pack.js');
-  var result = self.hljs.highlightAuto(event.data);
-  postMessage(result.value);
-}
-```
-
-
-## Установка библиотеки
-
-Highlight.js можно использовать в браузере прямо с CDN хостинга или скачать
-индивидуальную сборку, а также установив модуль на сервере. На
-[странице загрузки][5] подробно описаны все варианты.
-
-**Не подключайте GitHub напрямую.** Библиотека не предназначена для
-использования в виде исходного кода, а требует отдельной сборки. Если вам не
-подходит ни один из готовых вариантов, читайте [документацию по сборке][6].
-
-**Файл на CDN содержит не все языки.** Иначе он будет слишком большого размера.
-Если нужного вам языка нет в [категории "Common"][5], можно дообавить его
-вручную:
-
-```html
-<script src="//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.4.0/languages/go.min.js"></script>
-```
-
-**Про Almond.** Нужно задать имя модуля в оптимизаторе, например:
-
-```
-r.js -o name=hljs paths.hljs=/path/to/highlight out=highlight.js
-```
-
