+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

-# Why VNote (开发VNote的动机)
-## Markdown Editor & Note-Taking (Markdown编辑器与笔记管理)
-VNote tries to be a Markdown editor with notes management, or a note-taking application with pleasant Markdown support.
-
-Some popular note-taking applications provide Markdown support, such as WizNote, Youdao Note. But most of them provide poor Markdown experience (especially on Linux).
-
-There are always many powerful Markdown editors. But most of them lack the functionality to manage all your notes. During the design and implementation, VNote references to [CuteMarked](https://github.com/cloose/CuteMarkEd/) a lot.
-
-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。
-
-目前一些流行的笔记软件也提供Markdown的支持，比如为知笔记、有道云笔记等，但是大多数都只是简(liao)单(sheng)支(yu)持(wu)，特别是在Linux平台上更是体(can)验(bu)不(ren)佳(du)。
-
-当然，目前也有很多非常强大的专注于Markdown的编辑器。但是，大多数都不会提供笔记管理功能（作为一个编辑器，也没有必要提供），或者只是提供一个简单的文件系统浏览器。其中，CuteMarked就是一个流行的Markdown编辑器之一，VNote在实现的过程中也在很多地方参考借鉴了该软件。
-
-## Pleasant Markdown Experience (舒适的Markdown体验)
-VNote tries to minimize the gap between the edit and view of Markdown. Instead of using two panels to edit and preview simultaneously, VNote utilizes syntax highlight to help keeping track of the content. VNote also previews images in place when editing. It is said that you won't want to exit the edit mode when using VNote.
-
-VNote also learns a lot from Vim and Shell to provide many convenient and efficient shortcuts.
-
-VNote尝试尽量减小Markdown与生俱来的编辑和阅读之间的割裂感。目前很多编辑器通过左右两栏来同时编辑和预览Markdown，但是编辑和阅读还是割裂明显。VNote利用准确有意义的语法高亮来帮助用户追踪、辨认笔记内容，使得Markdown在编辑的时候也能和阅读一样提供良好的视觉、排版效果。同时，VNote支持编辑时原地预览图片，进一步减小割裂感。使用VNote后，你一定会更想留在编辑模式。
-
-另外，VNote也借鉴了Vim和Shell来提供很多非常方便高效的快捷键。
-
-# Features (功能)
-## Notebook-Based Notes Management (基于笔记本的管理)
-VNote uses **notebooks** to hold your notes. Like OneNote, a notebook can be hosted on any location in 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 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 directories. VNote supports copying or moving directories or notes within or between notebooks.
-
-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，你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。你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。
-
-![VNote Directory and File Panel](screenshots/vnote_002.png)
-
-## Simple Notes Management (直观的笔记管理)
-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.
-
-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，你也能方便访问你的数据。这样，你也可以使用第三方的文件同步服务来同步你的笔记，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。
-
-## Minimum Gap Between Edit and View (最小化编辑与阅读的鸿沟)
-VNote tries to provide the best-effort *WYSIWYG* for Markdown by utilizing proper syntax highlight and other features.
-
-通过使用有意义的语法高亮和其他一些功能，VNote尽可能为Markdown提供 *所见即所得* 的体验。
-
-### Syntax Highlight (语法高亮)
-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 Markdown, which is **superior** than almost all current Markdown editors.
-
-VNote支持精确的Markdown语法高亮。通过精心调试的高亮样式，VNote使得你能够轻松跟踪和阅读你的文档。
-
-VNote还支持Markdown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。
-
-![VNote Syntax Highlight](screenshots/vnote_003.png)
-
-### Live Image Preview (实时图片预览)
-VNote supports previewing the image link while editing. With this, you could just stay in edit mode as much as possible.
-
-You could select the image to copy it.
-
-VNote支持在编辑时预览图片链接。这样一来，你就能尽可能地留在编辑模式，避免频繁切换。
-
-如果想要拷贝图片，可以选取该图片，然后复制。
-
-![VNote Live Image Preview](screenshots/vnote_004.png)
-
-### Pleasant Image Experience (良好的图片体验)
-Just paste your image into the Markdown note, VNote will manage all other stuffs. VNote stores images in the `images` folder in the same directory with the note. VNote will pop up a window to preview the image when you insert an image. Furthermore, VNote will delete the image file automatically after you remove the image link.
-
-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会帮你管理所插入的图片。VNote将这些图片保存在和笔记同一目录下的 `images` 子目录中。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，当你移除笔记中的图片链接时，VNote会自动删除对应的图片。
-
-![VNote Image Insertion](screenshots/vnote_005.png)
-
-### Interactive Outline Viewer for Edit and View Mode (编辑和阅读时交互式大纲视图)
-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.
-
-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。
-
-![VNote Outline Viewer](screenshots/vnote_006.png)
-
-## Powerful Shortcuts (强大的快捷键)
-VNote supports many pleasant and powerful shortcuts which facilitate your editing, including **Captain Mode** and **Navigation Mode** which enable you to work without the mouse.
-
-Some Examples:
-
-- `Ctrl+W` to enter edit mode; `Ctrl+R` to save and enter read mode; `Ctrl+T` to maximize edit area;
-- `Ctrl+B`, `Ctrl+I`, `Ctrl+O` to insert bold, italic and inline-code text.
-
-Please refer to the help menu for more details.
-
-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 **舰长模式** 和 **导航模式**，它们能让你完全摆脱鼠标。
-
-一些例子：
-
-- `Ctrl+W` 进入编辑模式；`Ctrl+R` 保存并进入阅读模式；`Ctrl+T` 最大化编辑区；
-- `Ctrl+B`, `Ctrl+I`, `Ctrl+O` 插入粗体、斜体和行内代码。
-
-更多细节请参考帮助文档。
-
-## Window Split (窗口分割)
-VNote supports infinite horizontal window split, facilitating notes management and writing.
-
-VNote支持无限水平窗口分割，方便你进行笔记的整理和撰写。
-
-![VNote Window Split](screenshots/vnote_007.png)
-
-## Highly Configurable (高度可定制)
-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你的所有配置，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。
-
-## Others (其他)
-VNote also supports many other features, like:
-
-- Highlight current cursor line;
-- Highlight selected text;
-- Powerful search within the note;
-- Auto indent and auto list;
-
-VNote还支持其他很多的功能，比如：
-
-- 高亮当前行；
-- 高亮所选择的文本；
-- 强大的页内查找；
-- 自动缩进和自动列表；

-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-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
-
