Allows to define shortcodes for easy replacement. Handy for recurrent copy/paste’s from sites like YouTube or DailyMotion… But not only. You decide! Also allows you not to write un-valid tags that would be stripped out by WordPress (<code><object></code>s for example)
The syntaxt is Shortcodes’ one, but for legacy reasons you can use this syntax : [key:parameter1,parameter2,parameter3…]

Snips

Easy snippet/Shortcode editor plugin for Wordpress

George-Paul Crețu

Supports: Gutenberg, Elementor, TinyMCE and shortcode
Display your code snippets in a stylish way inside your content. The plugin uses shortcodes and also very intuitive TinyMCE interface.
Starting with v2.0.3, the plugin offers support to be used via a custom Elementor Widget.
Starting with v2.0.1, the plugin offers support to be used via a custom Gutenberg block.
It will continue to support the default way of adding the code snippet via shotcodes.
Code Snippet DM was inspired by the <a href="https://carbon.now.sh" rel="nofollow ugc">Carbon</a> project. 
We created a simple way to display your code snippets but also have control over the way it appears, thus making it more stylish. 
Also, on the front end in the top right you will find a <code>Copy Code</code> button that allows you to copy to clipboard the entired code snippet.
The plugin provides you with a TinyMCE button that will allow you to display the code or an option to use a shortcode.
You can open the shorcode <code>[dm_code_snippet]</code> and in the content inside and close it <code>[/dm_code_snippet]</code>.
<h4>Elementor widget</h4>
The Widget is called “Code Snippet DM” and can be found on the Basic list of Elementor Widget after you activate the plugin. Keywords that can be used to find it: code, snippet, dm.
Once the widget is added in the Elementor editor, it can be customized via the sidebar settings that will appear for each widget. The sidebar will include all the settings that are available for the shortcode. Some of the settings will be applied in real time in your editor.
The code styling (syntax highlight) and line numbers are only available on the front-end, in the editor you will not be able to preview the correct colors for the code or the line numbers.
<h4>Gutenberg block</h4>
The block is called “Code Snippet DM” and can be found in the embed section of Gutenberg blocks. Keywords that can be used to find it: code, snippet, dm.
Once the block is added in the Gutenberg editor, it can be customized via the sidebar settings that will appear for each block. The sidebar will include all the settings that are available for the shortcode. Some of the settings will be applied in real time in your editor.
The code styling (syntax highlight) and line numbers are only available on the front-end, in the editor you will not be able to preview the correct colors for the code or the line numbers.
<h4>Shortcode Options</h4>
There are a number of options that you can use in the shortcode:
<ul>
<li>background with options yes or no will enable/disable the color background (Default yes)</li>
<li>background-mobile with options yes or no will enable/disable the color background for mobile devices (Default yes)</li>
<li>bg-color accepts any HEX, RGB or RGBA value to change the background color (Default #abb8c3)</li>
<li>theme with options light or dark that changes the code editor theme (Default dark)</li>
<li>slim with options yes or no that changes the code editor from default to a slim version, ideal for one-line code (Default no)</li>
<li>line-numbers with options yes or no that will enable a left side line number for columns (Default no)</li>
<li>language with options clike, css, javascript, markup, perl, php, python, ruby, sql, typescript, shell will highlight the syntaxes based on what you select for your code (Default php)</li>
<li>wrap with options yes or no will wrap the code or add a horizontal scroll bar to display it as it is (Default no)</li>
<li>height allows you to input any value and will set the code snippet height to that value. Example: 500px. (Default is empty)</li>
<li>copy-text this is used for the text shown on the copy button. If it’s not added it will use the default option. (Default Copy Code)</li>
<li>copy-confirmed this is used for the text shown after you click the copy button. If it’s not added it will use the default option. (Default Copied)</li>
</ul>
Example of shortcode:
<pre><code>[dm_code_snippet background="yes" background-mobile="yes" slim="no" line-numbers="no" bg-color="#abb8c3" theme="light" language="css" wrapped="no" height="500px" copy-text="Get the Code!" copy-confirmed="You have it!"]<pre>
.dm-code-snippet.dark {
 background: $default-bg;
 padding: 40px 35px 45px 35px;
 margin: 30px 0;
}</pre>
[/dm_code_snippet]
</code></pre>
Important: 
* If you use the shortcode directly, make sure to wrap the code in <code><pre></pre></code> as in the example above. 
* If you want to add HTML using the shortcode, you’ll need to escape the HTML before pasting it in the shortcode. (You can easily find an escape tool online to convert the code) 
* If you have code (not HTML) that uses ‘</’ and you add it with the shortcode and not the and the TinyMCE button, you will need to escape ‘</’ from your code in order to properly display it.
Use the TinyMCE button if you don’t want to add the shortcode yourself. (see Screenshots)
