I have been using Rubular.com to come up with a regex pattern to try to parse this string for the values 596 and 777 and put them in an array:
Current mouse position: 596,777
I have been building this in IRB and testing it with t.scan(/(?:\\d)/)
This yields: ["4", "5", "1", "1", "1", "3", "7"]
which is not correct.
Does anyone have any pointers?
You have forgotten to put a quantifier :
t.scan(/\d+/)
The quantifier +
means one or more
Note: The non-capturing group (?:...)
is useless.
str = "Current mouse position: 596,777"
x, y = str.split()[-1].split(",")
puts x, y
--output:--
596
777
...
str = "Current mouse position: 596,777"
x = str[-7..-5]
y = str[-3..-1]
puts x, y
--output:--
596
777
