Checkpoint Timer is a gem to provide a very lightweight Ruby stopwatch timer.
The impetus for this was some performance diagnostic work that I was doing. I wanted to see how long different method calls were taking, but wanted something more lightweight than Ruby's Benchmark library.
Add this line to your application's Gemfile:
gem 'checkpoint_timer'
And then execute:
$ bundle
Or install it yourself as:
$ gem install checkpoint_timer
To use the timer, create an instance of the timer class.
timer = CheckpointTimer::Timer.new
timer.start
# ... execute code here
timer.checkpoint(logging: true, message: 'First checkpoint')
# ... execute some more code
timer.checkpoint(logging: true, message: 'Second checkpoint')
The timer can also be used without logging, if you wish to use the data differently
timer = CheckpointTimer::Timer.new
timer.start
# ... execute code here
elapsed_time = timer.checkpoint
The CheckpointTimer::Timer#checkpoint
method returns the elapsed time in seconds since the previous checkpoint.
Logging can also be enabled at the instance level.
timer = CheckpointTimer::Timer.new(log_all: true)
timer.start
# ... execute code here
elapsed_time = timer.checkpoint(message: 'Global logging is enabled')
