KotlinVerbalExpressions

This is a Kotlin implementation of VerbalExpressions, mostly based on the Java, Swift, and Scala implementations.

Examples

Simple URL test:

val verex = VerEx()
        .startOfLine()
        .then("http")
        .maybe("s")
        .then("://")
        .maybe("www")
        .anythingBut(" ")
        .endOfLine()

val url = "https://www.google.com"

// regular test with VerEx method
if(verex.test(url)) {
    println("Correct url")
}

// test with infix extension
if(url matches verex) {
    println("Correct url")
}

Replacing strings:

val str = "I like birds and bridges"

val verex = VerEx()
        .then("b")
        .anythingBut(" ").zeroOrMore()

val result = verex.replace(str, "trains")

println(result) // I like trains and trains

For more usage examples, see the included tests.
