How to write code, with syntax highlighting

This post demonstrates both inline code and code blocks with syntax highlighting.

Inline code is done using backticks to create something like this, which is handy for talking about a specific variable or a shortExpression++.

Code blocks are wrapped in the highlight liquid tag together with a keyword to define the language, like this:

{% highlight javascript %}
    ...JS here...
{% endhighlight %}

Examples

JavaScript

Here’s some JavaScript I borrowed from this StackOverflow post:

var modularpattern = (function() {
    // your module code goes here
    var sum = 0 ;

    return {
        add:function() {
            sum = sum + 1;
            return sum;
        },
        reset:function() {
            return sum = 0;    
        }  
    }   
}());
alert(modularpattern.add());    // alerts: 1
alert(modularpattern.add());    // alerts: 2
alert(modularpattern.reset());  // alerts: 0

Python

And here’s some Python from this tutorial:

class Employee:
   'Common base class for all employees'
   empCount = 0

   def __init__(self, name, salary):
      self.name = name
      self.salary = salary
      Employee.empCount += 1
   
   def displayCount(self):
     print "Total Employee %d" % Employee.empCount

   def displayEmployee(self):
      print "Name : ", self.name,  ", Salary: ", self.salary

Supported Languages

The highlighting is done with Rouge and at time of writing [their website] says they support 132 languages. I’m not 100% sure if all those are available in the version bundled within Jekyll. If you have successfully installed this theme, then you can run rougify list from the Terminal and you should get a list of supported languages. Or check out this wiki page.
