I tried so hard to find an example of Ruby using smalltalk message syntax.
You can do something like:
class Dictionary
attr_accessor :dict
def initialize()
@dict = {}
end
def at(*args)
if (args.length == 1) then
return @dict[args[0]]
end
@dict[args[0]] = args[1][:put]
end
end
dict = Dictionary.new
dict.at 3, put: 4
puts dict.dict
puts dict.at 3
But it's pretty expensive to disambiguate messages to "at" this way.
The JS approach was much simpler since each message like 'at:put:' or 'at'
were sent to appropriate receiver functions, whereas this is just a
spaghetti :\
I'm sure there's more elegant way of doing this in Ruby but I haven't found
it :|
