ExecTrace

Trace Ruby code, returning methods that were run, how many times they were called, how long they took to run, and the methods they called.

Add this line to your application's Gemfile:

gem 'exec_trace'

require "pp"
require "exec_trace"

result = exec_trace do
  u = User.new
  u.save!
end

pp result

exec_trace returns an array of arrays. Each top-level array is a top-level call in the exec_trace block. Frame consist 4 fields: file name + line number, calls, time in microseconds, and an array of frames that it called.

e.g.

[
  ["/Users/me/exec_trace/test/exec_trace_test.rb:23", 1, 52, [
    ["/Users/me/exec_trace/test/exec_trace_test.rb:24", 5, 2518388, []]
  ]]
]

• To compile the C extension: bundle exec rake compile
• To run the tests bundle exec rake test
