Edit: /opt/cpanel/ea-ruby27/root/usr/share/ruby/ruby-2.7.8/tracer.rb (6640B)

# frozen_string_literal: false
#--
# $Release Version: 0.3$
# $Revision: 1.12 $

##
# Outputs a source level execution trace of a Ruby program.
#
# It does this by registering an event handler with Kernel#set_trace_func for
# processing incoming events.  It also provides methods for filtering unwanted
# trace output (see Tracer.add_filter, Tracer.on, and Tracer.off).
#
# == Example
#
# Consider the following Ruby script
#
#   class A
#     def square(a)
#       return a*a
#     end
#   end
#
#   a = A.new
#   a.square(5)
#
# Running the above script using <code>ruby -r tracer example.rb</code> will
# output the following trace to STDOUT (Note you can also explicitly
# <code>require 'tracer'</code>)
#
#   #0:<internal:lib/rubygems/custom_require>:38:Kernel:<: -
#   #0:example.rb:3::-: class A
#   #0:example.rb:3::C: class A
#   #0:example.rb:4::-:   def square(a)
#   #0:example.rb:7::E: end
#   #0:example.rb:9::-: a = A.new
#   #0:example.rb:10::-: a.square(5)
#   #0:example.rb:4:A:>:   def square(a)
#   #0:example.rb:5:A:-:     return a*a
#   #0:example.rb:6:A:<:   end
