This library helps send escape sequences to Unix terminals. Now you don't need to use bloated dependencies like termbox or curses to position text in the terminal.
Include this in your shard.yml file:
dependencies:
ANSI:
github: Sevensidedmarble/ANSI
branch: masterThen run shards install to update your dependencies.
Require and include the ANSI module in your code:
require "ANSI"
The escape sequence helpers can be used like so:
require "ANSI"
ANSI.clear
ANSI.move(0, 1)
print "Print text at different positions."
ANSI.move(20, 20)
print "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat."
sleep 2
ANSI.save
ANSI.clear
print "Save the state of the screen."
sleep 2
ANSI.clear
ANSI.restore
ANSI.move(0, 2)
print "And restore it later."
sleep 2
ANSI.clear
size = ANSI.size
ANSI.move(0, 0)
print "Width: " + w.to_s + ", Height: " + h.to_s
sleep 2Most of the escape sequences are pretty self explanatory by name. There's a wonderful guide here if you want more details.
