I was working on my blog and moving some posts around when I kept getting a Psych::SyntaxError when generating it with Jekyll and ruby 1.9.x. Unfortunately the default stack trace doesn’t provide much information on what file was causing the issue, so a quick way to find out is opening up irb:

{% codeblock Example to run in irb - sample.rb lang:ruby %} require ‘yaml’ Dir.foreach(“source/_posts”).each {|f| YAML.load_file(“source/_posts/” + f) unless f == “.” || f == “..” } {% endcodeblock %}
