Endeavour

Endeavour is a simple gem that adds a try method to Object and NilClass instances. try permits calling a method on an object and returning nil rather than NoMethodError if the object is nil or does not respond to the method.

Usage

There are two ways to use try:

1. Call-based syntax (similar to Rails' Object#try)

car.try(:drive)

colors.try(:[], :red)

1. Delegate syntax (inspired by HoboSupport)

car.try.drive

colors.try[:red]

Installation

Add this line to your application's Gemfile:

gem 'endeavour'

And then execute:

$ bundle

Or install it yourself as:

$ gem install endeavour

Rails applications

Endeavour uses a Railtie and can be used after initialization without additional configuration.

Non-Rails applications

Call Endeavour.hook! early in your application.

Remove Endeavour

In some cases, you may want to remove Endeavour (say, if a naughty gem requires it). You can do so with Endeavour.remove_hook!
