Is it possible to refer to a parameter passed to a method within the passed block in ruby?
Category : Programming Languages

I hope I am not repeating anyone here, but I have been searching google and here and not coming up with anything. This question is really more a matter of "sexifying" my code.


What I am specifically trying to do is this:


Dir.new('some_directory').each do |file|
# is there a way to refer to the string 'some_directory' via a method or variable?
end

Scala - match a passed parameter against a passed type parameter in a recursive function
Category : Programming Languages

I have a node class, which can point to another node (via next). That node can be subclassed in different hierarchies. Then, I can have a chain of these various nodes, in an image of a single-linked list. And then, starting from an arbitrary node in that list, I want to search for the first one of a specific type. Therefore, I create a type-parametrized function check
