Middleman-Syntax

middleman-syntax is an extension for the Middleman static site generator that adds syntax highlighting via Rouge.

Gem Version Build Status Dependency Status Code Quality

Installation

If you're just getting started, install the middleman gem and generate a new project:

gem install middleman
middleman init MY_PROJECT

If you already have a Middleman project: Add gem "middleman-syntax" to your Gemfile and run bundle install.

This plugin will not work on Ruby 1.8! Rouge requires 1.9+, so we do too.

Configuration

activate :syntax

You can also pass options to Rouge:

activate :syntax, :line_numbers => true

The full set of options can be seen on your preview server's /__middleman/config/ page.

Helper

The extension adds a new code helper to Middleman that you can use from your templates. It will produce syntax-highlighted HTML wrapped in <pre class="highlight language-name"><code>...html...</code></pre>.

In Erb, use <% tags (not <%= tags):

<% code("ruby") do %>
def my_cool_method(message)
  puts message
end
<% end %>

In Haml, use =, not -:

= code('ruby') do
  puts "hello"

For more on Haml syntax, see the "Haml" section below.

CSS

On a default (i.e. unstyled) Middleman project, it will appear as if middleman-syntax isn't working, since obviously no CSS has been applied to color your code. You can use any Pygments-compatible stylesheet to style your code.

You can also let Rouge generate some CSS for you by creating a new stylesheet with a .css.erb extension in your Middleman project, and then including:

<%= Rouge::Themes::ThankfulEyes.render(:scope => '.highlight') %>

Rouge has ThankfulEyes, Colorful, Github, Base16, Base16::Solarized (like Octopress), Base16::Monokai, and Monokai themes.

Markdown

The extension also makes code blocks in Markdown produce highlighted code. Make sure you're using RedCarpet or Kramdown as your Markdown engine (in config.rb):

set :markdown_engine, :redcarpet
set :markdown, :fenced_code_blocks => true, :smartypants => true

## OR

set :markdown_engine, :kramdown

Now your Markdown will work just like it does on GitHub - you can write something like this with Redcarpet:

```ruby
def my_cool_method(message)
  puts message
end
```

or with Kramdown:

~~~ ruby
def my_cool_method(message)
  puts message
end
~~~

Haml

When using Haml, a :code filter is exposed for outputting highlighted code. Because Haml filters don't allow arguments, you must use a special comment to indicate the language of the code to be highlighted (or let Rouge guess):

#example
  :code
    # lang: ruby

    def foo
      puts 'bar'
    end

With the special # lang: <language tag> comment on the first line, the :code filter is just like calling the code helper, but without the indentation problems that Haml might otherwise have. However, if you prefer, you can use the code helper along with the :preserve filter, as explained below.

Indentation Problems

Some templating languages, like Haml, will indent your HTML for you, which will mess up code formatted in <pre> tags. When using Haml, either use the :code filter (recommended), use the :preserve filter, or add set :haml, { ugly: true } in your config.rb to turn off Haml's automatic indentation.

Example of using :preserve:

- code('ruby') do
  :preserve
    def foo
      puts 'bar'
    end
