To run the example project, clone the repo, and run pod install from the Example directory first.
The library is straightforward to use.
- Define your regular expression matching pattern as you normally would, including named groups (which are not supported by the default NSRegularExpression). Named groups follow the same method used in PHP: (?<name_of_group>your match)
let pattern = "(?w.+?)\s(?a.+?)$"
- Instantiate the main class using your pattern: BetterRegex(pattern: pattern) (it is better for performance to reuse that class for the same pattern every time you need it rather than reinstantiate it every time)
let test = BetterRegex(pattern: pattern)
- Obtain your matches back:
let regexOptions: NSMatchingOptions = NSMatchingOptions.WithTransparentBounds let matches: RegexResults = test.extractMatches("welcome all", options: regexOptions)
- Access your matches: the RegexResults structure that is returned with convenient accessor methods by name and index. Heye you can get your optional string for a key name using matches.getKey("test") or matches.getKey("amatch") or through numeric indexes for non-named groups and named groups alike via matches.getKey(0) for example.
A reasonably recent version of XCode
