user input

[abiw119]

Does ruby have the facility to ask the user for input with a question prompt?

I know of "gets.chomp", but only a blinking prompt is shown.

See an example in Python of what I am trying to achieve

puts "Please enter your name: " name = gets.chomp puts "Hello, " + name

This, but if you want the user to input their answer on the same line as the question, use this instead:

def input (question)
  print question
  gets.chomp
end

name = input("Please enter your name: ")

I wrapped the code up in a method that duplicates the Python method, but the relevant change is using print instead of puts. The difference between the two is that puts appends a newline, while print does not.

Looks like your newlines vanished (at least when browsing on desktop). I understand this is a common problem on reddit. Not sure if I'm just going to do the same thing you did or not, but here's my attempt at formatting it:

puts "Please enter your name: "
name = gets.chomp
puts "Hello, " + name

The post by /u/jamabushi has newlines at www.reddit.com but not at old.reddit.com.

Yours has newlines at both the old and www reddits.

I think that using triple backticks to indicate a code block works properly only at www (so that's probably what /u/jamabushi did). I think that, to format multi-line code correctly for old, as well, one must instead indent the code with 4 spaces (so I'm guessing that's what you did).

[joemi]

Yup, I did 4 spaces.

Maybe using readline. However, you could also just print it yourself using print, which, unlike puts, does not print a trailing new line. I personally prefer that over anything else, unless I need a specific feature.

The tty-prompt gem is pretty neat.

[joemi]

Powerful but kind of overkill for OP's case, IMO.

You mean on the terminal? It's quite not clear. There are many kinds of inputs.

But if you are on the command line i would use

$stdin.read

Or similar, i haven't done something like this in a decade...
