Swift Regular Expressions made easy

SwiftVerbalExpressions is a Swift library that helps to construct difficult regular expressions - ported from the awesome JavaScript VerbalExpressions.

Examples

Here's a couple of simple examples to give an idea of how VerbalExpressions works:

Testing if we have a valid URL

// Create an example of how to test for correctly formed URLs
let tester = VerEx()
    .startOfLine()
    .then("http")
    .maybe("s")
    .then("://")
    .maybe("www")
    .anythingBut(" ")
    .endOfLine()

// Create an example URL
let testMe = "https://www.google.com"

// Use test() method
if tester.test(testMe) {
    print("We have a correct URL") // This output will fire
}
else {
    print("The URL is incorrect")
}

// Use =~ operator
if testMe =~ tester {
    print("We have a correct URL") // This output will fire
}
else {
    print("The URL is incorrect")
}

prin(tester) // Outputs the actual expression used: "^(?:http)(?:s)?(?::\/\/)(?:www)?(?:[^ ]*)$"

Replacing strings

let replaceMe = "Replace bird with a duck"

// Create an expression that seeks for word "bird"
let verEx = VerEx().find("bird")

// Execute the expression like a normal RegExp object
let result = verEx.replace(replaceMe, with: "duck")

print(result) // Outputs "Replace duck with a duck"

Shorthand for string replace:

let result2 = VerEx().find("red").replace("We have a red house", with: "blue")

print(result2) // Outputs "We have a blue house"

Installation and use

This version is under testing, but it supports Swift Package Manager. Therefore it can be included in the project with:

        .package(
            url: "https://github.com/VerbalExpressions/SwiftVerbalExpressions.git",
            from: "

And:

        .target(
            name: "YourProject",
            dependencies: ["VerbalExpressions"]),
