Ruby and console output

Question

It is possible, generally, by means of Ruby library to output a symbol at specific location on a common Windows console screen, which seems to be 80x25 ?

The problem came up with the need to draw a specific 'tree' structure like this, for example:

│
├──x──y──z
│        │
│        ├──a──b──c
│        │
│        └──e──f──g
│
└──u──v──o

Answer 1

You could use a wrapper for Curses, like this one.

Answer 2

The Win32Console project should do what you want, and much more. Also, your question reminds me slightly of Ruby Quiz #14 (LCD Numbers).

Answer 3

If you're just interested generating trees in the console, this post shows you how to do it with hirb.
