How to use systax highlighter in your blog?

Introduction

I've been using Blogger as my blogging engine for a couple of weeks. I've been quite impressed at how easy it makes it to update your blogs look and feel and how free you are with the HTML and semantic layout of the pages.

One thing that seemed to be missing was allowing developers to copy and paste code into their blogs and allow other users to copy and paste the code from the blog into their own code.



Using SyntaxHighlighter Javascript Library

So in my search to find something better i came across this post which uses syntax highlighte

Adding Syntax Highlighter to Blogger Template

• Copy the following code

<link href='http://alexgorbatchev.com/pub/sh/current/styles/shCore.css' rel='stylesheet' type='text/css'/>  
<link href='http://alexgorbatchev.com/pub/sh/current/styles/shThemeDefault.css' rel='stylesheet' type='text/css'/>  
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shCore.js' type='text/javascript'></script>  <script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushCpp.js' type='text/javascript'></script>  
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushCSharp.js' type='text/javascript'></script>  
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushCss.js' type='text/javascript'></script>  
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushJava.js' type='text/javascript'></script>  
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushJScript.js' type='text/javascript'></script>  
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushPhp.js' type='text/javascript'></script>  
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushPython.js' type='text/javascript'></script>  
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushRuby.js' type='text/javascript'></script>  
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushSql.js' type='text/javascript'></script>  
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushVb.js' type='text/javascript'></script> 
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushXml.js' type='text/javascript'></script>  
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushPerl.js' type='text/javascript'></script>  
<script language='javascript'>  SyntaxHighlighter.config.bloggerMode = true; SyntaxHighlighter.config.clipboardSwf = 'http://alexgorbatchev.com/pub/sh/current/scripts/clipboard.swf'; SyntaxHighlighter.all(); </script>

• paste it into your Blogger Template just above the </head> tag
• Save the template
• Then you can start creating code blocks in your existing or new Blog entries.
• There are 2 ways to add a code block using syntaxhighlighter

<

Method 1: Using the script Tag

]]>



becomes:

Method 2: Using the pre Tag

becomes:

// Comment
public class Testing {
    public Testing() {
    }
 
    public void Method() {
        /* Another Comment
           on multiple lines */
        int x = 9;
    }
}

Code Containing Less that or Greater than

One person noticed that if you try and publish any code with < or > in it, you'll need to HTML Encode the code before adding it to the blog post using something like this. Then you'll be able to publish code with generic's such as the following:

static Dictionary<int, List<Delegate>> _delegate = new Dictionary<int, List<Delegate>>();

Conclusion

I have to say i'm pretty impressed. There are a couple of things you have to watch out for:

• The java script uses the <code> Tag. So as lots of blogger templates have styles for this tag you have to remove any styles before it looks like the above.
• If you paste in HTML or XML with <Tags>. You'll need to HTML encode them. Which is a bit of a shame, as i was hoping the CDATA would help get around that problem. Maybe in the next version.
