Using Unshift with Load Path's

Using unshift on your load path’s for Rails, Sinatra, etc, is a good way of ensuring that the file your including is going to be first.


vendor = File.join(File.dirname(__FILE__), 'vendor')
$LOAD_PATH.unshift File.expand_path(File.join(vendor, 'ultraviolet-0.10.5',  'lib'))

Odd Number of padding characters

In the case of an odd number of empty spaces in a length, Ruby will append the extra character to the right-hand side of the string.


irb(main):002:0> "Hello".center(10,"-")
=> "--Hello---"
