SyntaxHighlighter is a fully functional self-contained code syntax highlighter developed in JavaScript. Below is a sample of what it looks like in your blog.

    class Test
    {
        static void Main()
        {
          System.Console.WriteLine("Sample SyntaxHighlighter");
        }
    }

This tutorial will help you setup SyntaxHighlighter with GeeksWithBlogs.net in about 10 minutes. Even though this guide is specifically for GWB, you can use it on any other hosting provider that does not allow you to upload custom CSS/JavaScript.

It is recommended that if you are using LiveWriter to go ahead and download Code Snippet with SyntaxHighlighter Support to integrate this functionality within Live Writer.

1) Log into GWB and select Options->Configure

Now under the Custom CSS insert the following code at the top of the textbox:

@import url("http://alexgorbatchev.com/pub/sh/current/styles/shCore.css");
@import url("http://alexgorbatchev.com/pub/sh/current/styles/shThemeDefault.css");

Please note that you can change the default theme by changing the shThemeDefault.css to one listed below:

• shThemeDefault.css
• shThemeDjango.css
• shThemeEmacs.css
• shThemeFadeToGrey.css
• shThemeMidnight.css
• shThemeRDark.css

2) Under the Static News/Announcements insert the following code at the top:

<script type="text/javascript" src="http://alexgorbatchev.com/pub/sh/current/scripts/shCore.js"></script>    
<script type="text/javascript" language="javascript"    src="http://alexgorbatchev.com/pub/sh/current/scripts/shBrushCSharp.js"></script>
<script type="text/javascript" language="javascript"    src="http://alexgorbatchev.com/pub/sh/current/scripts/shBrushJScript.js"></script>
<script  src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushJava.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>

Please note that this will only give you support for Java, JavaScript and C Sharp. If you want more languages like Ruby and SQL. Then add the proper tags listed below. The reason that I didn’t add them is because I do not want to load languages that I will not be blogging about.

<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/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>

3) Now install Code Snippet with SyntaxHighlighter Support and launch Windows Live Writer. Click on the PreCode Snippet plugin add copy/paste your code into the windows. Make sure you select “PRE” and the Language that you are using. It should look similar to the following screenshot. 

After you finish editing the post, hit publish and your code should look nice and neat like the example shown earlier.
