Is it possible to express `stuff.map {|x| puts x}` more succinctly?

I would like to use some sort of shorthand to express the following:

stuff.map {|x| puts x}

to something like this:

stuff.map {puts}

I cannot figure out the syntax. Can someone show me how to do this?

Solution

  • Since you have an array, you could just write

    puts stuff

    However, in general, you can add a method to String or Object that can then be passed directly to an Enumerable. Since Symbol has a to_proc method, you can have that method called without needing a block.

    class Object; def myputs; puts self; nil; end; end

stuff.each &:myputs # or, even better, ...

stuff.myputs
