TOAST UI Editor provides **Markdown mode** and **WYSIWYG mode**. Depending on the type of use you want like production of *Markdown* or maybe to just edit the *Markdown*. The TOAST UI Editor can be helpful for both the usage. It offers **Markdown mode** and **WYSIWYG mode**, which can be switched any point in time. ### Productive Markdown Mode  **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 follows both [*CommonMark*](http://commonmark.org/) and [*GFM*](https://github.github.com/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. * **Live Preview** : Edit Markdown while keeping an eye on the rendered HTML. Your edits will be applied immediately. * **Scroll Sync** : Synchronous scrolling between Markdown and Preview. You don't need to scroll through each one separately. * **Syntax Highlight** : You can check broken Markdown syntax immediately. ### Easy WYSIWYG Mode  * **Table** : Through the context menu of the table, you can add or delete columns or rows of the table, and you can also arrange text in cells. * **Custom Block Editor** : The custom block area can be edited through the internal editor. * **Copy and Paste** : Paste anything from browser, screenshot, excel, powerpoint, etc. ### UI * **Toolbar** : Through the toolbar, you can style or add elements to the document you are editing.  * **Dark Theme** : You can use the dark theme.  ### Use of Various Extended Functions - Plugins  CommonMark and GFM are great, but we often need more abstraction. The TOAST UI Editor comes with powerful **Plugins** in compliance with the Markdown syntax. **Five basic plugins** are provided as follows, and can be downloaded and used with npm. * [**`chart`**](https://github.com/nhn/tui.editor/tree/master/plugins/chart) : A code block marked as a 'chart' will render [TOAST UI Chart](https://github.com/nhn/tui.chart). * [**`code-syntax-highlight`**](https://github.com/nhn/tui.editor/tree/master/plugins/code-syntax-highlight) : Highlight the code block area corresponding to the language provided by [Prism.js](https://prismjs.com/). * [**`color-syntax`**](https://github.com/nhn/tui.editor/tree/master/plugins/color-syntax) : Using [TOAST UI ColorPicker](https://github.com/nhn/tui.color-picker), you can change the color of the editing text with the GUI. * [**`table-merged-cell`**](https://github.com/nhn/tui.editor/tree/master/plugins/table-merged-cell) : You can merge columns of the table header and body area. * [**`uml`**](https://github.com/nhn/tui.editor/tree/master/plugins/uml) : A code block marked as an 'uml' will render [UML diagrams](http://plantuml.com/screenshot). ## 🎨 Features * [Viewer](https://github.com/nhn/tui.editor/tree/master/docs/en/viewer.md) : Supports a mode to display only markdown data without an editing area. * [Internationalization (i18n)](https://github.com/nhn/tui.editor/tree/master/docs/en/i18n.md) : Supports English, Dutch, Korean, Japanese, Chinese, Spanish, German, Russian, French, Ukrainian, Turkish, Finnish, Czech, Arabic, Polish, Galician, Swedish, Italian, Norwegian, Croatian + language and you can extend. * [Widget](https://github.com/nhn/tui.editor/tree/master/docs/en/widget.md) : This feature allows you to configure the rules that replaces the string matching to a specific `RegExp` with the widget node. * [Custom Block](https://github.com/nhn/tui.editor/tree/master/docs/en/custom-block.md) : Nodes not supported by Markdown can be defined through custom block.

Run npm scripts and develop yourself with the following process. ### Setup Fork `main` branch into your personal repository. Clone it to local computer. Install node modules. Before starting development, you should check if there are any errors. ```sh $ git clone https://github.com/{your-personal-repo}/tui.editor.git $ npm install $ npm run build toastmark $ npm run test editor ``` > TOAST UI Editor uses [npm workspace](https://docs.npmjs.com/cli/v7/using-npm/workspaces/), so you need to set the environment based on [npm7](https://github.blog/2021-02-02-npm-7-is-now-generally-available/). If subversion is used, dependencies must be installed by moving direct paths per package. ### Develop You can see your code reflected as soon as you save the code by running a server. Don't miss adding test cases and then make green rights. #### Run snowpack-dev-server [snowpack](https://www.snowpack.dev/) allows you to run a development server without bundling. ``` sh $ npm run serve editor ``` #### Run webpack-dev-server If testing of legacy browsers is required, the development server can still be run using a [webpack](https://webpack.js.org/). ``` sh $ npm run serve:ie editor ``` #### Run test ``` sh $ npm test editor ``` ### Pull Request Before uploading your PR, run test one last time to check if there are any errors. If it has no errors, commit and then push it!
