Good Morning, Team! |
|||
Every so often, I like to write a Ruby script that says good morning to my team in a fun way. Here is the one I made this morning which mimics the famous bouncing DVD logo.
require "io/console"
greeting = [71, 111, 111, 100, 32, 77, 111, 114, 110, 105, 110, 103, 44, 32, 84, 101, 97, 109, 33].map(&:chr).join
colors = ["\e[31m", "\e[33m", "\e[32m", "\e[36m", "\e[34m", "\e[35m"]
rows, columns = begin
io.console.winsize
rescue
[24, 80]
end
g_width = greeting.size
g_height = 1
x = rand(columns - g_width)
y = rand(rows - g_height)
dx = 1
dy = 1
frame = 0
loop do
print "\e[h\e[2j"
puts "\n" * y
color = colors[frame % colors.size]
print(" " * x + color + greeting + "\e[0m")
sleep 0.05
if (x + dx < 0) || (x + g_width + dx > columns)
dx = -dx
frame += 1
end
if (y + dy < 0) || (y + g_height + dy > rows)
dy = -dy
frame += 1
end
x += dx
y += dy
sleep 0.25
end
