One liner in Ruby for displaying a prompt, getting input, and assigning to a variable?

Question

Often I find myself doing the following:

print "Input text: "
input = gets.strip

Is there a graceful way to do this in one line? Something like:

puts "Input text: #{input = gets.strip}"

The problem with this is that it waits for the input before displaying the prompt. Any ideas?

Answer 1

Check out highline:

require "highline/import"
input = ask "Input text: "

Answer 2

The problem with your proposed solution is that the string to be printed can't be built until the input is read, stripped, and assigned. You could separate each line with a semicolon:

$ ruby -e 'print "Input text: "; input=gets.strip; puts input'
Input text: foo
foo

Answer 3

I think going with something like what Marc-Andre suggested is going to be the way to go, but why bring in a whole ton of code when you can just define a two line function at the top of whatever script you're going to use:

def prompt(*args)
    print(*args)
    gets
end

name = prompt "Input name: "
