[ruby/irb] Add measure command
You can use "measure" command to check performance in IRB like below:
irb(main):001:0> 3
=> 3
irb(main):002:0> measure
TIME is added.
=> nil
irb(main):003:0> 3
processing time: 0.000058s
=> 3
irb(main):004:0> measure :off
=> nil
irb(main):005:0> 3
=> 3
You can set "measure :on" by "IRB.conf[:MEASURE] = true" in .irbrc, and, also,
set custom performance check method:
IRB.conf[:MEASURE_PROC][:CUSTOM] = proc { |context, code, line_no, &block|
time = Time.now
result = block.()
now = Time.now
puts 'custom processing time: %fs' % (Time.now - time) if IRB.conf[:MEASURE]
result
}
