How to pass parameters to a proc when calling it by a method?

Question

proc = Proc.new do |name|
  puts "Thank you #{name}!"
end
def thank
  yield
end

---

proc.call # output nothing, just fine
proc.call('God') # => Thank you God!

thank &proc # output nothing, too. Fine;
thank &proc('God') # Error!
thank &proc.call('God') # Error!
thank proc.call('God') # Error!
# So, what should I do if I have to pass the 'God' to the proc and use the 'thank' method at the same time ?

Thanks :)

Answer 1

I think the best way is:

def thank name
  yield name if block_given?
end

Answer 2

def thank(arg, &block)
  yield arg
end

proc = Proc.new do|name|
   puts "Thank you #{name}"
end

Then you can do:

thank("God", &proc)

Answer 3

a different way to what Nada proposed (it's the same, just different syntax):

proc = Proc.new do |name|
    puts "thank you #{name}"
end

def thank(proc_argument, name)
    proc_argument.call(name)
end

thank(proc, "for the music") #=> "thank you for the music"
thank(proc, "for the songs you're singing") #=> "thank you for the songs you're singing"

It works, but I don't like it. Nevertheless it will help readers understand HOW procs and blocks are used.
