Ruby Curry Example

curry-example.rb

def three(a, b, c)
  puts "a: #{a}, b: #{b}, c: #{c}"
end

def four(a, b, c, d)
  puts "a: #{a}, b: #{b}, c: #{c}, d: #{d}"
end

three(:x, :y, :z)
# a: x, b: y, c: z
four(:w, :x, :y, :z)
# a: w, b: x, c: y, d: z

# And then curry all but the last argument.

san = method(:three).to_proc.curry.(:q).(:w)
yon = method(:four).to_proc.curry.(:z).(:x).(:c)

san.(:e)
# a: q, b: w, c: e
yon.(:v)
# a: z, b: x, c: c, d: v
