16 Free Javascript Code Syntax Highlighters For Better Programming
Dainis Graveris
If you are programmer or actually if you at least have some basic coding skills, you’ll find this article useful. For example just look at this page source – without highlighting that whole code is just a bunch of plain black text and it is really hard to find specific things if everything looks the same. Thankfully there are many highlighting scripts available, for example Notepad++ also supports and highlights different code snippets. These code syntax highlighters actually are doing mainly the same thing, but with more options, big coding language support, better integration – really in our days you just need to choose one – there are too many tools available anyway.
Use these syntax highlighters in daily coding or just in cases where you are sharing code with friends, want to add that code in your blog post (by the way there is SyntaxHighlighter WordPress plugin available too) or just want to rapidly read and maintain it – use online syntax highlighters in that case and pick your favorite one from this article!
1. SyntaxHighlighter
I definitely think this syntax highlighter tool should be your choice – this tool is supported very well and offers many options, extensions and integrations with other programs and platforms, but however I want to offer you other tools too to choose from.
SyntaxHighlighter is here to help a developer/coder to post code snippets online with ease and have it look pretty. It’s 100% Java Script based and it doesn’t care what you have on your server.
The idea behind SyntaxHighlighter is to allow insertion of colored code snippets on a web page without relying on any server side scripts. SyntaxHighlighter isn’t for those looking for ability to edit highlighted code.
Extensions & Integration – check out this page too, because you can find there WordPress extensions, Ruby on Rail plugins and much more integration extensions, should be handy!

16. Syntax highlighter for JavaScript
This online tool will syntax highlight JavaScript 1.2. code. The highlighting is based on patterns, it will not test for valid JavaScript. Put your code into the box, and tell it to syntax highlight. It may take a little while to highlight large amounts of code, be patient and let it finish.
The output format is HTML – designed so that you can create a Web page displaying your code. I enjoyed how this tool really displays code in very clean way!
Of course there are also many programs with already built in syntax highlighting support, but these online versions and JS scripts offer bigger control over highlighting and flexibility.

Posted 578 days ago 20jQuery Syntax Highlighter is a new one based on version 3 of Alex Gorbatchev’s Syntax Highlighter – a really really really popular plain javascript syntax highlighter.
It supports such things as `code` and `pre` blocks, able to use classnames like `language-javascript` to indicate which language we would like to highlight, as well as being able to wordwrap code. You only need to include one javascript file and it will autoload the rest saving configuration time. And you can copy and paste code by selecting it normally instead of having to open a raw view like many others. It can be further customised by using the HTML5 data attribute `data-sh` or via specifying options at initialisation. A great stable choice which is updated regularly.
Here’s the link :-)

Posted 880 days ago 14This is an excellent list, and I like your choice of Alex’s syntaxhighlighter as nr 1. Not sure if you still monitor the comments on this thread (there are some non-deleted spam comments….) but if you do, it’d be great if you could add a reference to my list of “all” brushes for SyntaxHighlighter. The brushes that come by default are nice, but there are many more available from all over the internet. I compiled a list of all I can find and try to keep it as up to date as possible.
If you happen to know any other brushes that I haven’t mentioned, I’d be happy to include them!

Posted 937 days ago 11I had previously been using plain textareas. I always thought these pretty highlighted boxes on sites were done server side. Will check a few of these out and use one in future.

Posted 938 days ago 7Wow, I had no idea there were that many syntax highlighting projects.
When I was looking for one, I found the first one you listed, SyntaxHighlighter, which has worked very well for me. I especially like that the author provides a hosted version of the scripts so you don’t need to figure out where to put them (convenient when using it in Blogger, for example).

Posted 937 days ago 9Hi Dainis,
Aptana is more to IDE, and the loading speed is pretty slow. If you want a powerful code editor with syntax highlighting feature, you can go for Notepad++.
