Question

all. I'm writing a chat client in Go as a proof-of-concept of a library I'm in the process of writing. It needs to take user input and print incoming messages in the same terminal window. Consider the following.

user@debian ~ $ ./client
no session> 192.168.1.100
> Hello, there!
Hi!
> So, did you get that feature working yet?
Nope. I thought you were going to ask on StackOverflow.
>> Yeah, I'm aski

If another message arrives while I'm typing, then it should produce the following.

user@debian ~ $ ./client
no session> 192.168.1.100
> Hello, there!
Hi!
> So, did you get that feature working yet?
Nope. I thought you were going to ask on StackOverflow.
Or did you want me to?
>> Yeah, I'm aski

Is there a way to do this in Go?

Thanks :)

Answer 1

If you've ever used a console application that behaves like that, it probably used a library like ncurses to do that. You wouldn't want to program that yourself because it's quite complex.

For Go I'd recommend termbox-go. It's easy to pick up and has a well structured api.
