Question

I’m using this command to get the screen resolution:

system_profiler SPDisplaysDataType | grep Resolution

This returns your screen resolution of the form:

Resolution: 1366 x 768

The problem that I’m being faced with, is finding a way to get the values: 1366 and 768 separately by possibly using a regex in Ruby. The reason why I need to get these two values is so that I can use them here:

image = Image.new(x, y)

where x and y would be 1366 and 768 respectively. My question is how can I those two values by themselves?

Answer 1

matches = str.match(/(\d+) x (\d+)/)
hor = matches[1]
ver = matches[2]
