How to remove spacing after displaying input (gets)

Hello programmers of all levels!

So I've got a question. I'm learning Ruby and I am a little confused how to remove some random spacing after displaying input. In example;

puts "Hello! What's your name?"
name = gets
puts "Oh, nice to meet you #{name}!"

The result is actually;

Oh, nice to meet you Noah        #This.....
!          #... And this are what I am talking about
=> nil

I figured out how to do it once, but as I write larger programs, it seems to become more and more complicated to keep it from adding such spacing.

I figure there is a solution somewhere. And thanks to everyone who offers a helping hand. :)

Edit: So the TTH forums have an awkward auto-rearrange of, coincidentally, where I put my code. I hope it is readable, and, if someone knows of proper forum posting of code ([CODE][/CODE] aren't working, as can be used elsewhere), I'd also be grateful to know that as well.

Thanks again!

Hi Noah,

This post should help with code-formatting: Posting Code to the Forum.

With regards to your actual question, are you getting a newline before the exclamation point? If so, I think the .chomp method may be of use. For instance:

name = gets.chomp

Hello, and thanks for a double dose of help!

As for my code, the exclamation is getting a newline. Ahh, I think I see now.

I know about chomp, but maybe if I display a variable (ie, #{}) it will throw off the rest of the code.

I'll give it a try and give an update.

Thanks!

Edit: Bingo, .chomp fixes everything. I think I remember now, that a string without .chomp returns as 'My String\n'.

Thanks, Joseph!
