Middleman Disqus

Middleman-Disqus is a Middleman extension that generates the Disqus embed code, and keeps your config in config.rb, where it belongs.

Installation

Specify the dependency in your project's Gemfile:

# Gemfile
gem "middleman-disqus"

Activate the Disqus extension in your project's config.rb. (n.b. read important information about shortnames)

# config.rb
activate :disqus do |d|
  d.shortname = 'your-shortname' # Replace with your Disqus shortname.
end

In your layout or template call disqus and/or discus_count and include the results in the page:

Haml:

/ link with `#disqus_thread` is optional if not using `disqus_count` -->
%a{:href => "http://example.com/foo.html#disqus_thread"} Comments

= disqus
= disqus_count

ERB:

<!-- link with `#disqus_thread` is optional if not using `disqus_count` -->
<a href="http://example.com/foo.html#disqus_thread">Comments</a>

<%= disqus %>
<%= disqus_count %>

Helper methods

The following helper methods are available within your templates:

disqus will include the Disqus embed.js code and display comments.
disqus_count will include the Disqus count.js code for displaying a comment count on links when you set #disqus_thread to the href attribute.

Configuration: config.rb

activate :disqus do |d|
  # Disqus shotname, without '.disqus.com' on the end (default = nil)
  d.shortname = 'your_shortname'
end

Configuration: YAML Frontmatter

You can set per page configuration variables in the YAML Fontmatter, these are used as parameters for Disqus' behaviors and settings.

For full details about what they do, see Disqus JavaScript configuration variables

IMPORTANT: Do not use real shortnames during development

If you use the live/production shortname during development and testing, expect to litter your Disqus account with discussions that you can't delete!

You have two options:

Create a special testing/development shortname for use during development.
Only include Disqus in builds, not when running middleman server.

You can set different options for build and development by using Middleman's environment specific settings, for example:

# config.rb
configure :development do
  activate :disqus do |d|
    # using a special shortname
    d.shortname = "development-shortname"
    # or setting to `nil` will stop Disqus loading
    d.shortname = nil
  end
end

configure :build do
  activate :disqus do |d|
    # using a different shortname for production builds
    d.shortname = "production-shortname"
  end
end
