Syntax highlighting	formatting	rouge, pygments, prettify, color coding,	August 12, 2015	You can apply syntax highlighting to your code. This theme uses pygments and applies color coding based on the lexer you specify.

About syntax highlighting

For syntax highlighting, use fenced code blocks optionally followed by the language syntax you want:

```ruby
    def foo
      puts 'foo'
    end
```

This looks as follows:

    def foo
      puts 'foo'
    end

Fenced code blocks require a blank line before and after.

If you're using an HTML file, you can also use the highlight command with Liquid markup:

{% raw %}{% highlight ruby %}
    def foo
      puts 'foo'
    end
{% endhighlight %}{% endraw %}

It renders the same:

{% highlight ruby %} def foo puts 'foo' end {% endhighlight %}

The theme has syntax highlighting specified in the configuration file as follows:

highlighter: pygments

You can use another highlighter such as rouge.

The syntax highlighting is done via the css/syntax.css file.

Available Pygments lexers

The keywords you must add to specify the highlighting (in the previous example, ruby) are called "lexers." You can search for "pygments lexers" or go directly to Available lexers to see what values you can use. Here are some common ones I use:

• js
• html
• yaml
• css
• json
• php
• java
• cpp
• dotnet
• xml
• http
