Code Sample plugin

Insert and embed syntax highlighted code snippets.

Contribute to this page
+ toolbar button

The Code Sample plugin (codesample) lets a user insert and embed syntax color highlighted code snippets into the editable area. It also adds a button to the toolbar which on click will open a dialog box to accept raw code input.

  selector: 'textarea',  // change this value according to your HTML
  plugins: 'codesample',
  toolbar: 'codesample'

By default, codesample uses to embed the code samples within the editor and works out of the box. That is, when a user copies valid code syntax into the editable area the code will be automatically formatted according to Prism default CSS rules.

Prism.js and prism.css need to be added to a page for syntax highlighting to work. See the instructions below to learn how to do this.

Using Prism.js on your web page

You need to add prism.js and prism.css to your page in order to get the syntax highlighted code samples on your webpage (as created by the Code Sample plugin). The Code Sample plugin uses the following languages: markup, javascript, css, php, ruby, python, java, c, csharp and cpp. You can generate the prism.js and prism.css files on the download page at the Prism website.

Example of using the Prism.js script

<link rel="stylesheet" type="text/css" href="prism.css">
<script src="prism.js"></script>
<pre class="language-markup"><code>...</code></pre>

Live example



Note: This feature is only available for TinyMCE 5.2 and later.

This configuration option allows a global Prism.js version to be used when highlighting code sample blocks, instead of using the Prism.js version bundled inside the codesample plugin. This allows for a custom version of Prism.js, including additional languages, to be used.

When using this option, ensure that Prism.js and any language add-ons are loaded on the site, alongside the TinyMCE script:

<script src="prism.js" data-manual></script>
<script src="tinymce.js"></script>

Type: Boolean

Default value: false

Possible values: true, false
