Brave

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.

Installation

Add this line to your application's Gemfile:

gem 'brave'

And then execute:

$ bundle

Or install it yourself as:

$ gem install brave

Usage

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

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
