Blogger: Adding syntax highlighter to Blogger

As we know it is really hard to post any source code to the blogger as there is no Syntax Highlighting option by default to the blogger (A Big Deficiency).

After doing some web search first I came across a Javascript tool named syntaxhighlighter and then I came across Heisencoder's post on how to add the syntaxhighlighter option to the blogger template.

NOTE: We are about to tweak the HTML code of the blogger template. Inorder to know how to edit the HTML code of the blogger template check this post.

NOTE: For safety precautions click "Download Full Template" link to download full html code of your present blog's template.

Select "Expand Widget Templates" option to see the full html code in the editor. Now we have to make our hands dirty as we are about to add some code into our blogger template code.

1. Go to http://syntaxhighlighter.googlecode.com/svn/trunk/Styles/SyntaxHighlighter.css, and perform "select all" and "copy" the whole code and paste it at the end of the css section of your blogger html template (i.e.,  before ]]--></b:skin>).

2. Before the </head> tag, paste the following code:


<!-- Add-in CSS for syntax highlighting -->
<script src='http://syntaxhighlighter.googlecode.com/svn/trunk/Scripts/shCore.js' type='text/javascript'></script>
<script src='http://syntaxhighlighter.googlecode.com/svn/trunk/Scripts/shBrushCpp.js' type='text/javascript'></script>
<script src='http://syntaxhighlighter.googlecode.com/svn/trunk/Scripts/shBrushCSharp.js' type='text/javascript'></script>
<script src='http://syntaxhighlighter.googlecode.com/svn/trunk/Scripts/shBrushCss.js' type='text/javascript'></script>
<script src='http://syntaxhighlighter.googlecode.com/svn/trunk/Scripts/shBrushDelphi.js' type='text/javascript'></script>
<script src='http://syntaxhighlighter.googlecode.com/svn/trunk/Scripts/shBrushJava.js' type='text/javascript'></script>
<script src='http://syntaxhighlighter.googlecode.com/svn/trunk/Scripts/shBrushJScript.js' type='text/javascript'></script>
<script src='http://syntaxhighlighter.googlecode.com/svn/trunk/Scripts/shBrushPhp.js' type='text/javascript'></script>
<script src='http://syntaxhighlighter.googlecode.com/svn/trunk/Scripts/shBrushPython.js' type='text/javascript'></script>
<script src='http://syntaxhighlighter.googlecode.com/svn/trunk/Scripts/shBrushRuby.js' type='text/javascript'></script>
<script src='http://syntaxhighlighter.googlecode.com/svn/trunk/Scripts/shBrushSql.js' type='text/javascript'></script>
<script src='http://syntaxhighlighter.googlecode.com/svn/trunk/Scripts/shBrushVb.js' type='text/javascript'></script>
<script src='http://syntaxhighlighter.googlecode.com/svn/trunk/Scripts/shBrushXml.js' type='text/javascript'></script>

NOTE: Simply remove lines for languages which you will never use (for example, Delphi) -- it will save some loading time of the blogs.

3. Before the </body> tag, insert the following:
<!-- Add-in Script for syntax highlighting -->
<script language='javascript'>
dp.SyntaxHighlighter.BloggerMode();
dp.SyntaxHighlighter.HighlightAll('code');
</script>

NOTE: Tweaking of the Blogger HTML template code is complete. So before you save the template code just click on "Preview" button to see if the code is not crashing & working fine.

4. While posting a post that has source code then click on "Edit Html" tab and post the source code between pre tags shown below
<pre name="code" class="cpp">
...Your html-escaped code goes here...
</pre>

In the above code substitute "cpp" with whatever language you're using. Choices: cpp, c, c++, c#, c-sharp, csharp, css, delphi, pascal, java, js, jscript, javascript, php, py, python, rb, ruby, rails, ror, sql, vb, vb.net, xml, html, xhtml, xslt. Full list can be accessed at Supported languages.

NOTE: Instead of remembering the code everytime we can add this HTML code simply into the template so that it is displayed whenever we create a new post. Click on "Settings" tab and then "formatting" sub-tab and post the html code in the "Post Template" box. As a result next whenever we create a new post it is displayed when we click "Edit Html".

We have to perform HTML escaping which can be done in the sites like Centricle, Accessify.
