Overview

PathList

A PathList is an array containing 1..n paths. It is useful to regroup paths and make lookups on them.

Usage

path = PathList.new(ENV['PATH'])
path.find 'env'            #=> "/usr/bin/env"

# This is already done when including the library
$:.class                   #=> Array
$:.extend PathList::Finder
$:.find_ext = 'rb'

$:.find 'uri'              #=> "/usr/lib/ruby/1.8/uri.rb"
