Question

I’m doing this:

distanceFunc = lambda do |a,b|
  Leven.wordLevenWithOps(a, b)
end
links = prims(phrases, &distanceFunc)

It works but I would like to something shorter like:

links = prims(phrases, &Leven.wordLevenWithOps)

What is the right syntax ?

Answer 1

you can get class method of any class as

ClassName.method(:method_name) 

and you can pass its reference

for your case(considering wordLevenWithOps as class method in Leven) following would work;

links = prims(phrases, &Leven.method(:wordLevenWithOps))

hope this help.
