I have a Windows laptop and I just recently installed Git, choosing to use Git Bash as my terminal because I am more familiar with the commands. I've installed Ruby but when I try to run this sample program the terminal executes the 'gets' method and then the 'puts'

The following code

puts("Welcome to Calculator")
puts("What's the first number")
number1=gets
puts number1

When run from Git Bash results in this interaction with the terminal

2
Welcome to Calculator!
What's the first number?
2

instead of 

Welcome to Calculator!
What's the first number?
2
2

I've tested it in a different environment and the program works fine. Is the problem caused by trying to use Git Bash to execute code on a Windows machine? Should I refrain from doing so?

  • So in git bash does it not print "Welcome to Calculator" until you type 2? Commented Dec 23, 2016 at 1:43
  • Yes. If I include any more 'gets' it waits for me to type them all in to display the 'puts' Commented Dec 23, 2016 at 2:42
  • Seems like @kbyte has a good answer to me. I can't think of any other reason. Commented Dec 23, 2016 at 2:52

Take a look here:

Cmd and Git bash have a different result when run a Python code

The windows terminal uses strange buffered streams. Try to force the flush like the python example.
