Overview

Calculates the time running from one location to another inside your code. More info: https://github.com/MarioRuiz/timify/

attr_accessor: min_time_to_show: minimum time to show the elapsed time when calling 'add' method show: print out results on screen

attr_reader: name: name given for the Timify instance initial_time: when the instance was created total: total time elapsed max_time_spent: maximum time measured for this instance

Constructor Details

#initialize(name, min_time_to_show: 0, show: true) ⇒ Timify

input: name: name for the instance min_time_to_show: minimum time to show the elapsed time when calling 'add' method show: print out results on screen

examples: t = Timify.new :create_user t.show = false $tim = Timify.new :dbprocess, show:false, min_time_to_show: 0.5

Instance Method Details

#add(*label) ⇒ Object

Adds a new point to count the time elapsed. It will count from the last 'add' call or Timify creation in case of the first 'add'.

input: label: (optional) In case supplied it will summarize all the ones with the same label

output: (float) time elapsed in seconds

examples: t=Timify.new :example t.add; run_sqls; t.add :database t.add #some processes t.add #some processes send_email_alert if t.add > 0.2 #some processes do_log(t.totals[:message]) if t.add > 0.5
