ruby - Should I specify &block argument in def? -

-

in ruby, better (style?) specify method takes &block or not?

the choice merely seems matter of style long method body contains yield.

for example, given:

def abc1(a, c)   puts   yield   puts c end  def abc2(a, c, &block)   puts   yield   puts c end

the following 2 calls:

abc1('a', 'c') { puts 'b' } abc2('a', 'c') { puts 'b' }

each print , return same things:

a b c => nil

so, if it's matter of style, what's convention (or better style)?

with current code first 1 better. while using yield then, no need use &block, implicit. yes, 1 thing remind, have pass block while using yield, if not there error. although error can handled using block_given?.

ruby's yield statement gives control user specified block method's body. so, if using again &block redundant, don't need use it.
