# Rake task to automatically run something (i.e. specs) when code files are changed
# By Peter Çoopér
#
# Motivation: I couldn't get autotest to run on my Sinatra project for some reason but realized
# it didn't require overengineering. Just detect when a file is changed and then re-run the specs!
#
# Examples:
#      # rake on_update "rake"
#      # rake on_update "spec spec/user_spec.rb"
#

# This file extends the Kernel's require function and adds the 
# AutoReload module which allows to reload files once they have changed
# on the disk.
#
# Basically, you just require your files as usual, and if you want to update
# the files, either call AutoReload.reload(file) or AutoReload.reload_all.
#
# Usage:
#   irb -rautoload

// Add a Mustache.js templating function to your JavaScript:

Mustache.template = function(templateString) {
  return function () {
    if (arguments.length < 1) {
      // With no arguments, return the raw template -- useful for rendering
      // partials.
      return templateString;
    } else {
      return Mustache.to_html(templateString, arguments[0], arguments[1]);

Instrument Anything in Rails 3

With Rails 3.0 released a few weeks ago I've migrated a few apps and I'm constantly finding useful new improvements. One such improvement is the ability to log anything in the same way that Rails internally logs ActiveRecord and ActionView. By default Rails 3 logs look slightly spiffier than those produced by Rails 2.3: (notice the second line has been cleaned up)

Started GET "/" for 127.0.0.1 at Mon Sep 06 01:07:11 -0400 2010
