Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Code syntaxer for CKEditor5.

Readme

ckeditor5-syntaxer

ckeditor5-syntaxer is a 3. party free code syntaxer for CKEditor 5.

ckeditor5-syntaxer is just a wrapper to be used together with a syntaxing library like eg. HighlightJs. ckeditor5-syntaxer wraps a block of code and set the language as a class on that wrapper - it is then the responsibility of a syntaxing library to do the actually syntaxing based on the language class :

Full ckeditor5-syntaxer official documentation here : CKSyntaxer - a CKEditor 5 plugin. The full documentation also contains step-by-step creation of the editor. Below is a short usage documentation.

//#1 : In your CKEditor5 build file ADD a reference to ckeditor5-syntaxer:

// app.js

import Autoformat from '@ckeditor/ckeditor5-autoformat/src/autoformat';
import Bold from '@ckeditor/ckeditor5-basic-styles/src/bold';
import Italic from '@ckeditor/ckeditor5-basic-styles/src/italic';
import BlockQuote from '@ckeditor/ckeditor5-block-quote/src/blockquote';
import Syntaxer from 'ckeditor5-syntaxer'; // ADD THIS
// ...

ClassicEditor.builtinPlugins = [
    Essentials,
    Autoformat,
    Bold,
    Italic,
    BlockQuote,
    Image,
    ImageUpload,
    Syntaxer // ADD THIS
    // ...
]

//#2 : Then creating the CKEditor5 set the SyntaxerPlugin languages and wrapper element :

ClassicEditor.create(document.querySelector('#editor'), {
    syntaxer: {
		languages: ['c#', 'php', 'java', 'sql', 'javascript', 'json', 'xml', 'html', 'css', 'markdown'],
		element: 'pre' // choose 'pre' or 'div'
    }
    // ...
});

//#3 : In the page that consumes the result of your CKEditor5, make a reference to a syntaxing library, here HighlightJs, in the header of that page :

<html>
	<head>
		<link rel="stylesheet" href="//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.15.6/styles/default.min.css">
		<script src="//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.15.6/highlight.min.js"></script>
		// ...
	</head>
	<body>
		// ...
	</body>
</html>

//#4 : In the page that consumes the result of your CKEditor5, call the syntaxer function of your syntaxer library, here shown for HighlightJs :

document.addEventListener("DOMContentLoaded", () => {
	var codeBlocks = document.querySelectorAll("pre.code");
	codeBlocks.forEach((codeBlock) => {
		hljs.highlightBlock(codeBlock);
	});
}
