Collect statistics on the use of open source

TOAST UI Editor applies Google Analytics (GA) to collect statistics on the use of open source, in order to identify how widely TOAST UI Editor is used throughout the world. It also serves as important index to determine the future course of projects. location.hostname (e.g. > “ui.toast.com") is to be collected and the sole purpose is nothing but to measure statistics on the usage. To disable GA, use the following usageStatistics options when creating editor.

var options = {
    ...
    usageStatistics: false
}
var editor = new Editor(options);

Or, include tui-code-snippet.js (v1.4.0 or later) and then immediately write the options as follows:

tui.usageStatistics = false;

CommonMark + GFM Specifications

Today CommonMark is the de-facto Markdown standard. GFM (GitHub Flavored Markdown) is another popular specification based on CommonMark - maintained by GitHub, which is the Markdown mostly used. TOAST UI Editor respects both CommonMark and GFM specifications. Write documents with ease using productive tools provided by TOAST UI Editor and you can easily open the produced document wherever the specifications are supported.

Powerful Extensions

CommonMark and GFM are great, but we often need more abstraction. The TOAST UI Editor comes with powerful Extensions in compliance with the Markdown syntax. You also get the flexibility to develop your own extensions using simple APIs.

Here are some of the extensions you can start with:

Color picker: ColorPicker provides an easy way to color text with a GUI tool box
Chart code block: A Code block marked as a 'chart' will render charts
UML code block: A Code block marked as an 'uml' will render UML diagrams
Table merge: You can merge columns and rows in tables

🔨 Usage

The code provided underneath is for npm + bundler. If you are using bower please see Getting started with bower.

Editor

HTML

Place a <div></div> where you want TOAST UI Editor rendered.

<body>
...
<div id="editSection"></div>
...
</body>

javascript

Add dependencies & initialize Editor class with given element to make an Editor.

// deps for editor
require('codemirror/lib/codemirror.css'); // codemirror
require('tui-editor/dist/tui-editor.css'); // editor ui
require('tui-editor/dist/tui-editor-contents.css'); // editor content
require('highlight.js/styles/github.css'); // code block highlight

var Editor = require('tui-editor');
...
var editor = new Editor({
    el: document.querySelector('#editSection'),
    initialEditType: 'markdown',
    previewStyle: 'vertical',
    height: '300px'
});

or you can use jquery plugin.

$('#editSection').tuiEditor({
    initialEditType: 'markdown',
    previewStyle: 'vertical',
    height: '300px'
});

or if using the CDN

var editor = new tui.Editor({
    el: document.querySelector('#editSection'),
    initialEditType: 'markdown',
    previewStyle: 'vertical',
    height: '300px'
});

options

height: Height in string or auto ex) 300px | auto
initialValue: Initial value. Set Markdown string
initialEditType: Initial type to show markdown | wysiwyg
previewType: Preview style of Markdown mode tab | vertical
usageStatistics: Let us know the hostname. We want to learn from you how you are using the editor. You are free to disable it. true | false

Viewer

TOAST UI Editor provides a Viewer in case you want to show Markdown content without loading the editor. The Viewer is much lighter than the editor.

// deps for viewer.
require('tui-editor/dist/tui-editor-contents.css'); // editor content
require('highlight.js/styles/github.css'); // code block highlight

var Viewer = require('tui-editor/dist/tui-editor-Viewer');
...
var editor = new Viewer({
    el: document.querySelector('#viewerSection'),
    height: '500px',
    initialValue: '# content to be rendered'
});
...

Be careful not to load both the editor and the viewer at the same time because the editor already contains the viewer function, you can initialize editor Editor.factory() and set the viewer option to value true in order to make the editor a viewer. You can also call getHTML() to render the HTML.

var Editor = require('tui-editor');
...
var editor = Editor.factory({
    el: document.querySelector('#viewerSection'),
    viewer: true,
    height: '500px',
    initialValue: '# content to be rendered'
});
...

TOAST UI Editor respects CommonMark and GFM. So any Markdown renderer including markdownit can handle the content made using TOAST UI Editor. You can also use any of these renderer in place of TOAST UI Editor Viewer.
