About
io-line.rb is an IO library that can reuse one or more lines of output.
The implementation uses the
io-console
library from Ruby's stdlib.
Examples
One line
The following example counts from 1 up to 100. The number from the previous
iteration is replaced with a number from the current iteration, and the same
line is reused until the iteration is completed. It is possible to end the
current line, and move onto the next line with the IO::Line#end method:
require "io/line"
line = IO::Line.new($stdout)
1.upto(100) do |number|
line.rewind.print(number)
sleep 0.1
end
line.end
