Ruby on Rails

This Jackbox feature showcases an alternative way to refine classes,
that also illustrates some additional uses of our modular
closures/injectors. For this to happen, we rely once again on our trusty
method #lets. Take a look at this example code:


# Injector declaration

StringExtensions = injector :StringExtensions do
def to_s
super + '++++'
end
end


# Jackbox Re-Classing

lets String do
include StringExtensions
end
str = String('boo')

assert(
str.to_s == 'boo++++'
)

assert(
String.new('bar).to_s == "bar"
)
