Sass plugin for Jekyll

sass_converter.rb

module Jekyll
  # Sass plugin to convert .scss to .css
  # 
  # Note: This is configured to use the new css like syntax available in sass.
  require 'sass'
  class SassConverter < Converter
    safe true
    priority :low

     def matches(ext)
      ext =~ /scss/i
    end

    def output_ext(ext)
      ".css"
    end

    def convert(content)
      begin
        puts "Performing Sass Conversion."
        engine = Sass::Engine.new(content, :syntax => :scss, :load_paths => ["./css/"])
        engine.render
      rescue StandardError => e
        puts "!!! SASS Error: " + e.message
      end
    end
  end
end

Thanks for this. I´ve added an additional line in the rescue clause to produce a visible error on the page itself and not only in the log file. Helped me a lot during development:

rescue StandardError => e
  error = "!!! SASS Error: #{e.message} !!!"
  puts error
  "body:before{ content:\"#{error}\"; color: red; font-size: 20px; }"
end

This may be overkill, but for a more complete solution you may want to use an asset pipeline. The Jekyll Asset Pipeline gem supports most languages (e.g. Scss, Less, CoffeeScript, Erb, etc.) and has a bunch of features (e.g. asset tagging, minification, gzipping, etc.) that set it apart. It also seems to be the fastest growing Jekyll-related gem these days, which I take to mean that it is gaining traction in the community.

I added a colorize function to highlight sass errors in the console output:

def colorize(text, color)
  "#{color}#{text}\e[0m"
end

Then applyied it on the error thrown by Sass:

puts colorize("SASS Error: "+e.message, "\e[31m")

e[31m = red

Run jekyll serve --watch to see the errors colorized in red.

Cheers! :)

Thanks @wolfeidau. I have put this plugin in the _plugins directory of my jekyll project but I can't figure out why my scss files are not converted. Am I missing something?

Thanks!

I'm in the same boat as @Omarfouad. I've added it and nothing is converting for me. What am I missing?

@cjdsie, @Omarfouad. I think you have to make sure you include a YAML front-matter statement at the top of any file (in this case a scss file) that you want to convert.

This is mentioned in Jekyll's Plugin page under Converters: "Jekyll will only convert files that have a YAML header at the top, even for converters you add using a plugin."

For example:

---
title: stylesheet.scss

---

body { background: red; }

That seemed to do the trick for me.

Front matter can be empty, thus

---

---

should work as well.

Had to change
engine = Sass::Engine.new(content, :syntax => :scss, :load_paths => ["./css/"])
to
engine = Sass::Engine.new(content, :syntax => :scss, :load_paths => ["#{@config['source']}/css/"])

to support running jekyll build with a different --source flag
