* http://rubysideshow.rubyforge.org/irb_callbacks == DESCRIPTION: This gem adds callbacks to irb, intended for you to override at your discretion. == FEATURES: irb's control flow looks like this: loop: * prompt * eval * output This gem adds three callbacks to each phase. module IRB: * self.before_prompt * self.around_prompt (call yield) * self.after_prompt * self.before_eval * self.around_eval (call yield) * self.after_eval * self.before_output * self.around_output (call yield) * self.after_output == SYNOPSIS: # Here's my ~/.irbrc file (which is run at irb startup) require 'rubygems' require 'irb_callbacks' require 'benchmark' # This little snippet will time each command run via the console. module IRB def self.around_eval(&block) @timing = Benchmark.realtime do block.call end end def self.after_output puts "=> #{'%.3f' % @timing} seconds" end end # And a sample irb session: $ irb irb(main):001:0> 1_000_000.times { |x| x + 1 } => 1000000 => 0.330 seconds == CAVEATS: The three around_* callbacks all require you to call the block that's passed in. If you don't do it, undefined behavior may occur. == INSTALL: * sudo gem install irb_callbacks == LICENSE: (The MIT License) Copyright (c) 2008 Mike Judge Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the 'Software'), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
