How to write a new Extension

Add definition in Plist:

    <string>Test Extension</string>

Map handler via commandIdentifier in class:

// Implement your modify strategy using block (you can implement as singleton dict)
// [ "commandIdentifier": handler ]
override func handlers() -> Dictionary<String, xTextModifyHandler> {
    return [
        "test.extension": { text: String -> String in text }

* Handle with regex:

// Override performCommandWithInvocation like that
override func perform(with invocation: XCSourceEditorCommandInvocation, completionHandler: (NSError?) -> Void) {
    if let handler = self.handlers()[invocation.commandIdentifier] {
        xTextModifier.select(invocation: invocation, pattern: "regex", handler: handler)
