Welcome to StackEdit!

Hey! I’m your first Markdown document in StackEdit[^stackedit]. Don’t delete me, I’m very helpful! I can be recovered anyway in the Utils tab of the Settings dialog.


StackEdit stores your documents in your browser, which means all your documents are automatically saved locally and are accessible offline!


  • StackEdit is accessible offline after the application has been loaded for the first time.
  • Your local documents are not shared between different browsers or computers.
  • Clearing your browser’s data may delete all your local documents! Make sure your documents are synchronized with Google Drive or Dropbox (check out the Synchronization section).

Create a document

The document panel is accessible using the button in the navigation bar. You can create a new document by clicking New document in the document panel.

Switch to another document

All your local documents are listed in the document panel. You can switch from one to another by clicking a document in the list or you can toggle documents using Ctrl+[ and Ctrl+].

Rename a document

You can rename the current document by clicking the document title in the navigation bar.

Delete a document

You can delete the current document by clicking Delete document in the document panel.

Export a document

You can save the current document to a file by clicking Export to disk from the menu panel.

Tip: Check out the Publish a document section for a description of the different output formats.


StackEdit can be combined with Google Drive and Dropbox to have your documents saved in the Cloud. The synchronization mechanism takes care of uploading your modifications or downloading the latest version of your documents.


  • Full access to Google Drive or Dropbox is required to be able to import any document in StackEdit. Permission restrictions can be configured in the settings.
  • Imported documents are downloaded in your browser and are not transmitted to a server.
  • If you experience problems saving your documents on Google Drive, check and optionally disable browser extensions, such as Disconnect.

Open a document

You can open a document from Google Drive or the Dropbox by opening the Synchronize sub-menu and by clicking Open from…. Once opened, any modification in your document will be automatically synchronized with the file in your Google Drive / Dropbox account.

Save a document

You can save any document by opening the Synchronize sub-menu and by clicking Save on…. Even if your document is already synchronized with Google Drive or Dropbox, you can export it to a another location. StackEdit can synchronize one document with multiple locations and accounts.

Synchronize a document

Once your document is linked to a Google Drive or a Dropbox file, StackEdit will periodically (every 3 minutes) synchronize it by downloading/uploading any modification. A merge will be performed if necessary and conflicts will be detected.

If you just have modified your document and you want to force the synchronization, click the button in the navigation bar.

Note: The button is disabled when you have no document to synchronize.

Manage document synchronization

Since one document can be synchronized with multiple locations, you can list and manage synchronized locations by clicking Manage synchronization in the Synchronize sub-menu. This will let you remove synchronization locations that are associated to your document.

Note: If you delete the file from Google Drive or from Dropbox, the document will no longer be synchronized with that location.


Once you are happy with your document, you can publish it on different websites directly from StackEdit. As for now, StackEdit can publish on Blogger, Dropbox, Gist, GitHub, Google Drive, Tumblr, WordPress and on any SSH server.

Publish a document

You can publish your document by opening the Publish sub-menu and by choosing a website. In the dialog box, you can choose the publication format:

  • Markdown, to publish the Markdown text on a website that can interpret it (GitHub for instance),
  • HTML, to publish the document converted into HTML (on a blog for example),
  • Template, to have a full control of the output.

Note: The default template is a simple webpage wrapping your document in HTML format. You can customize it in the Advanced tab of the Settings dialog.

Update a publication

After publishing, StackEdit will keep your document linked to that publication which makes it easy for you to update it. Once you have modified your document and you want to update your publication, click on the button in the navigation bar.

Note: The button is disabled when your document has not been published yet.

Manage document publication

Since one document can be published on multiple locations, you can list and manage publish locations by clicking Manage publication in the menu panel. This will let you remove publication locations that are associated to your document.

Note: If the file has been removed from the website or the blog, the document will no longer be published on that location.

Markdown Extra

StackEdit supports Markdown Extra, which extends Markdown syntax with some nice features.

Tip: You can disable any Markdown Extra feature in the Extensions tab of the Settings dialog.

Note: You can find more information about Markdown syntax here and Markdown Extra extension here.


Markdown Extra has a special syntax for tables:

Item Value
Computer $1600
Phone $12
Pipe $1

You can specify column alignment with one or two colons:

Item Value Qty
Computer $1600 5
Phone $12 12
Pipe $1 234

Definition Lists

Markdown Extra has a special syntax for definition lists too:

Term 1
Term 2
: Definition A
: Definition B

Term 3

: Definition C

: Definition D

> part of definition D

Fenced code blocks

GitHub’s fenced code blocks are also supported with Highlight.js syntax highlighting:

// Foo
var bar = 0;

Tip: To use Prettify instead of Highlight.js, just configure the Markdown Extra extension in the Settings dialog.

Note: You can find more information:

  • about Prettify syntax highlighting here,
  • about Highlight.js syntax highlighting here.


You can create footnotes like this[^footnote].

[^footnote]: Here is the text of the footnote.


SmartyPants converts ASCII punctuation characters into “smart” typographic punctuation HTML entities. For example:

Single backticks 'Isn't this fun?' ‘Isn’t this fun?’
Quotes "Isn't this fun?" “Isn’t this fun?”
Dashes -- is en-dash, --- is em-dash — is en-dash, —- is em-dash

Table of contents

You can insert a table of contents using the marker [TOC]:



You can render LaTeX mathematical expressions using MathJax, as on

The Gamma function satisfying $\Gamma(n) = (n-1)!\quad\forall n\in\mathbb N$ is via the Euler integral

\Gamma(z) = \int_0^\infty t^{z-1}e^{-t}dt\,.

Tip: To make sure mathematical expressions are rendered properly on your website, include MathJax into your template:

<script type="text/javascript" src=""></script>

Note: You can find more information about LaTeX mathematical expressions here.

UML diagrams

You can also render sequence diagrams like this:

Alice->Bob: Hello Bob, how are you?
Note right of Bob: Bob thinks
Bob-->Alice: I am good thanks!

And flow charts like this:

st=>start: Start
op=>operation: My Operation
cond=>condition: Yes or No?


Note: You can find more information:

  • about Sequence diagrams syntax here,
  • about Flow charts syntax here.

其中知乎上的一篇翻译的文章ReactJS 傻瓜教程


1. React是组件化的,而且是仅仅View层面的,还需要配合其他MVC的框架。
2. React有自己的渲染方式,一种类似XML的,将Html和Javascript结合的叫JSX的东西。



仅是看quick start这一篇,只记住了一点。







每个组件都是React Create出来的一个element,它们包含但不仅限于html。

var CommentBox = React.createClass({
  render: function() {
    return (
      <div className="commentBox">
        <CommentList data={} />
        <CommentForm />


var CommentList = React.createClass({
  render: function() {
    var commentNodes = (comment) {
      return (
        <Comment author={}>
    return (
      <div className="commentList">


React里有一个简单的预编译器,用于将JSX这种语法糖转换成纯的JavaScript代码。作为语法糖,确实JSX 语句比纯 JavaScript 更加容易使用

这个 div 标签不是真实的DOM节点;他们是 React div 组件的实例。


当然command+, 在Pereference的Keymap中也能找到并且修改快捷键。

  • 双击shift:查找函数或者文件
  • Shift+command+O:查找文件
  • Alt+command+L:排版格式化


currentColor 代表了当前元素被应用的color颜色值。使用它可以将当前这个颜色值应用到其他属性上,或者嵌套元素的其他属性上。



    color: #33; 
    border: 5px solid currentColor;
    box-shadow: 0 0 5px solid currentColor;


本地调试的时候总是说Origin * is not allowed by Access-Control-Allow-Origin好烦。


$open -a "Google Chrome" --args --disable-web-security


这时可以选择安装chrome extension的方式。CORS插件。

$sudo vim .bash_profile


export CLICOLOR=1

$sudo vim /etc/hosts

$sudo apachectl start

这时,打开你得浏览器,输入“http://localhost”, 可以看到“It Works!”的页面。这个index.html 文件位于“/Library(资源库)/WebServer/Documents/”下。这是Apache的默认根目录。


Apache 的安装目录在:/etc/apache2/ 默认是隐藏的。

$open /etc/apache2


$defaults write AppleShowAllFiles -bool true

$defaults write AppleShowAllFiles -bool false

修改/etc/apache2/httpd.conf 文件,就是修改apache的配置文件。这个文件默认是只读的,修改请加管理员权限 sudo

修改完之后,记得重启apache 服务

$sudo apachectl restart


  1. 打开 /etc/apache2/httpd.conf文件

    $sudo vim /etc/apache2/httpd.conf
  1. 找到/Library/WebServer/Documents,你换成你自己的目录:

  2. 重启服务。

    $sudo apachectl restart   


可能会遇到403 Forbidden,这时就需要修改的配置了。

  1. 打开 /etc/apache2/httpd.conf文件

    $sudo vim /etc/apache2/httpd.conf
  2. 找到Directory标签,将标签内的配置Deny from all删掉,改成allow from all

    <Directory />
        Options Indexes FollowSymLinks
        AllowOverride None
        Order deny,allow
        allow from all
  3. 然后继续重启

Ps:Options Indexes FollowSymLinks中得Indexes是指如果你的文件根目录里有 index.html,浏览器就会显示 index.html的内容。
如果没有 index.html,浏览器就会显示文件根目录的目录列表,目录列表包括文件根目录下的文件和子目录。


  1. 打开 /etc/apache2/httpd.conf文件

    $sudo vim /etc/apache2/httpd.conf
  2. 找到Listen 关键字,后面跟的就是端口号了,改掉!

    Listen 8089
  3. 然后继续重启

Mac OS-Android studio was unable to find a valid JVM解决办法

Mac OSx 上安装Anroid Studio v1.0,官方说明是需要JDK 1.6以上&JRE 6以上版本的支持。






右键显示包内容,在目录下找到 info.plist 并用任意文本编辑器打开
