I like to do high fives, take photographs and make cool things with Ruby.


Dublin – part 2

Two more photos from the trip to Dublin last November.

My grandmother, the best grandma in the whole world turned 95 and celebrated with a party last weekend. xoxo

Breakfast at Mynewsdesk

Every Monday morning at 8:00 breakfast is served for the Mynewsdesk employees at our headquarter in Stockholm. It became some sort of tradition for me to take a photograph of my breakfast every morning and here’s the result from 2012’s breakfasts.

Jekyll code highlighting on Heroku

The built in code highlighter in Jekyll doesn’t work on Heroku due to some issues with Python. I came up with a work around by using the Pygmentize gem instead.


Add the Pygmentize gem to your gemfile:

gem 'pygmentize'

And run bundle install


Create a new file in the _plugins directory with the name highlight.rb. Paste the following code to make the built in code highlighter use the new Pygmentize gem:

require 'pygmentize'
class Jekyll::HighlightBlock < Liquid::Block
  def render_pygments(context, code)
    @options[:encoding] = 'utf-8'
    output = add_code_tags(
      Pygmentize.process(code, @lang),

    output = context["pygments_prefix"] + output if context["pygments_prefix"]
    output = output + context["pygments_suffix"] if context["pygments_suffix"]


Just use the standard highlight blocks as usual:

{% highlight ruby %}
gem 'pygmentize'
{% endhighlight %}

Create Jekyll posts from the command line

I got tired on creating new files manually for each new post a write so I put together this little command line task with Thor.

It creates a new file in the _posts directory with today’s date, parses the parameters to command as the post’s title and adds that as a slug to the new file. It then writes a default yaml template to the file (as specified in the script).

Running thor jekyll:new New and shiny post will for example create the file _posts/, populate it with an yaml template and finally open the file in my favorite editor.

How to

Add the following to your Gemfile:

gem 'thor'
gem 'stringex'

Run bundle install and create a jekyll.thor file with the following contents:

require "stringex"
class Jekyll < Thor
  desc "new", "create a new post"
  method_option :editor, :default => "subl"
  def new(*title)
    title = title.join(" ")
    date ='%Y-%m-%d')
    filename = "_posts/#{date}-#{title.to_url}.md"

    if File.exist?(filename)
      abort("#{filename} already exists!")

    puts "Creating new post: #{filename}"
    open(filename, 'w') do |post|
      post.puts "---"
      post.puts "layout: post"
      post.puts "title: \"#{title.gsub(/&/,'&amp;')}\""
      post.puts "tags:"
      post.puts " -"
      post.puts "---"

    system(options[:editor], filename)

Use the new command:

$ thor jekyll:new The title of the new post

You can even specify which editor to open the new file with:

$ thor jekyll:new The title of the new post --editor=vim

The default editor is Sublime Text 2, just change on line 4 in jekyll.thor if an other editor is preferred.

Merry Christmas
