# HoboSupport

HoboSupport is a mixed bag of core ruby extensions that have been extracted from the [Hobo][] project

[Hobo]: http://hobocentral.net

    >> require 'hobosupport'
    >> HoboSupport::VERSION
    => "0.1"

## Object extensions

### Object#is_a?

Extended to allow multiple types to be checked in one go

    >> "foo".is_a?(String, Symbol)
    => true
    >> :foo.is_a?(String, Symbol)
    => true
    >> 1.is_a?(String, Symbol)
    => false
    
Still works the old way

    >> "foo".is_a?(String)
    => true
    >> :foo.is_a?(String)
    => false
    
    
## Method call extensions

### Object#_?

We have the "." operator to call methods on objects. These extensions introduce two "special dots". "`._?.`" only calls the method if the receiver is not `nil`.

    >> "foo"._?.length
    => 3
    >> nil._?.length
    => nil
    

### Object#try

"`.try`" only calls the method if the receiver responds to that method.

    >> "foo".try.length
    => 3
    >> :foo.try.length
    => nil
