Validator

A simple string validation library.

Introduction

Validator is a library that can be used to validate a string against set of Rule objects:

public protocol Rule {        
    func validate(_ value: String) -> Error?
}

This simple test demonstrates Validator's ease-of-use:

import JValidator

let validator = Validator.shared
let rules = [Rule] = [CharacterSetRule(in: lettersAndExtras), NoEmojiRule()]

XCTAssertNotNil(validator.validateString("abc😎", withRules: rules), "abc😎 is not a valid name")
XCTAssertNil(validator.validateString("jarrod", withRules: rules), "jarrod is a valid name")

If a string is invalid, then an Error is returned. Custom ValidatorErrors are defined in Validator and can be mapped however you prefer.

Installation

CocoaPods

To install Validator using CocoaPods, add pod 'Validator' to your Podfile, then follow the integration tutorial here.

Contributions

Validator welcomes fixes, improvements, and feature additions. If you'd like to contribute, open a pull request with a detailed description of your changes.

As a rule of thumb, if you're proposing an API-breaking change or a change to existing functionality, consider proposing it by opening an issue, rather than a pull request; we'll use the issue as a public forum for discussing whether the proposal makes sense or not.
