IrbBenchmark

IrbBenchmark wraps irb commands evaluations in a Benchmark.measure{ ... } block and displays the results after the command execution. Example:

irb(main):001:0> sleep 1
  0.000000   0.000000   0.000000 (  1.000323)
=> 1

Installation

$ gem install irb-benchmark

Usage

Single shot usage

$ irb -rirb-benchmark

In .irbrc

Classic require

require 'irb-benchmark'

irbtools option

Irbtools.add_library :irb_benchmark, late: true

Note that the former option can be used with irbtools too, so it is the preferred.

Enabling / disabling

IrbBenchmark.enabled = true / false

Wirb / irbtools integration

It auto-detects Wirb presence and FancyIrb configuration for colorized output (both are used by the well-known irbtools gem).

Known issues

The usage with FancyIrb alters the benchmark measures adding a small overhead.

Bugs, feature requests, pull requests

Fell free to open an issue for bugs or feature requests, or fork it and make a pull request.

Thanks to

janlelis and its fancy_irb which saved me from spending time to discover how to monkey-patch Irb :-)
