The pattern must be wrapped between r" and " like following:
1
let pattern = r"ab+"
Examples
1 2 3 4 5 6 7 8 9101112
// matches any digit
let pattern = r"\d+"
io.print(pattern == "65") // 1
io.print(pattern in "some string") // 0
io.print(pattern in "i am 21 years old") // 1
io.print(pattern.match("i am 21 years old")) // <null>
io.print(pattern.search("i am 21 years old").group(0)) // 21
for i in pattern.match_all("18.07.2020") {
io.print(i.group(0))
}
