coldnebo / rails_trace.rb

Last active August 15, 2024 15:15

This Rack middleware for Rails3 lets you see a call-trace of the lines of ruby code in your application invoked during a single request. Only code within your app is considered (i.e. in the /app folder). This expands on my previous attempt (https://gist.github.com/3077744). Example of output in comments below.

	require 'singleton'

	# outputs a colored call-trace graph to the Rails logger of the lines of ruby code
	# invoked during a single request.
	#
	# Example:
	#
	# 1) Make sure this file is loaded in an initializer
	#
	# 2) Add the following to your application.rb in Rails3:

a set of diophantine equations relating father and son...


	# Interesting relationships:

	# Say the father's age is 72 and the son's age is 40.
	# The father was born in 1940 and the son in 1972.

	# Isn't that curious?

	# In english, the dad's age is the current year minus the dad's birth year,
	# the right-most 2 digits of the dad's birth year is the son's age,
