Does anyone know why this code returns false?

fun main() {
    val str = "123test123"
    val matches = Regex("""test""", RegexOption.MULTILINE).matches(str)
    println(matches)
}

because it doesn’t match the entire input

Does Regex work differently in Kotlin? I know that this matches in JavaScript for example. How can I get this to match in Kotlin?

[gian]

maybe you can try containsMatchIn instead of matches

Try regex in str, it's the same as containsMatchIn but in operator form.

Thanks, this works 👍

And yes: JS and Java/Kotlin regex behavior (and syntax) is different. JS "match" is similar to Kotlin "find": Regex("test").find("123test456")?.groupValues
