Tryit

Another approach to Rail's Object#try. This is the result of a StackOverflow discussion between Sergey Gopkalo and Michael Kohl.

Instead of

obj.try(:met1).try(:met2).try(:met3).to_s

you can do this

obj.tryit { met1.met2.met3.to_s }

or this (the preferred form):

tryit { obj.met1.met2.met3.to_s }

You can customize which exception to catch:

TryIt.exceptions << ZeroDivisionError
tryit { 1/0 }  # will not raise exceptions

There's also the possibility to define your own exception handlers:

TryIt.handler = lambda { |_| puts "message from tryit" }
tryit { raise NoMethodError } # will print "message from tryit"

Installation

Add this line to your application's Gemfile:

gem 'tryit'

And then execute:

$ bundle

Or install it yourself:

$ gem install tryit

Todo

• Find a way to make the exception list not global.
