How to put code in your blog posts in WordPress?

Question

I want to be able to show something like:

function foo()
{
    return "bar";
}

Is there a plugin?

I installed one called Code Markup, but this doesn't add any code options when I am adding a new post (at least not that I am seeing).

Answer 1

I use the SyntaxHighlighter plugin. It works well, is simple to use, and supports a good variety of languages.

See an article on my site for example output.

Answer 2

No need for a plugin.

All WordPress Setups come with this option available (unless you change the default setup).

Just enclose it as follows:

<code>function foo()
{
    return "bar";
}</code>

You can find it below.

Answer 3

Suppose I have a code written using Ruby.

In my blog post I would do

[sourcecode language="ruby"]
def hello
  puts "Hi! This is Rohit here"
end
[/sourcecode]

WordPress has this as a default feature. I haven't used any plugin for this.
