This library allows you to do method chaining or to run an arbitrary block of code without the hassle of dealing directly with either NoMethodError or a specific list of exceptions the block could raise.
Add this line to your application's Gemfile:
gem 'brave'
And then execute:
$ bundle
Or install it yourself as:
$ gem install brave
require "brave"
hash = {foo: "bar"}
hash[:foo].length # 3
hash[:boo].length # NoMethodError
Brave.be { hash[:foo].length } # 3
Brave.be { hash[:boo].length } # nil
class Person
attr_accessor :name
end
person_a = Person.new
person_a.name = "Foo"
person_b = Person.new
person_a.name.upcase # "FOO"
person_b.name.upcase # NoMethodError
Brave.be { person_a.name.upcase } # "Foo"
Brave.be { person_b.name.upcase } # nil
