Evaluate selection as Groovy

// This is micro-plugin for IntelliJ to evaluate selected text as Groovy expression
// (Note that this code can only be executed within this plugin https://github.com/dkandalov/live-plugin)

// You can try it on the following code. Should produce 14.
/*
 def ints = [1, 2, 3]
 ints.sum{ it * it }

registerAction("EvalSelectionAsGroovy", "alt shift E", "ToolsMenu", "Eval as Groovy") { event ->
	def editor = currentEditorIn(event.project)
	if (editor == null) return
	def text = editor.selectionModel.selectedText
	if (text == null) return

	try {
		def result = Eval.me(text)
		appendToSelectionIn(editor, result.toString(), event.project)
	} catch (Exception e) {
		showInConsole(e, "EvalSelectionAsGroovy", event.project)
	}
}
show("Registered 'Eval Selection as Groovy' action<br/>Use Alt+Shift+E to run it")

static appendToSelectionIn(Editor editor, String text, Project project) {
	runDocumentWriteAction(project) {
		editor.with {
			def lineNumber = document.getLineNumber(selectionModel.selectionEnd)
			def lineEndOffset = document.getLineEndOffset(lineNumber)
			document.insertString(lineEndOffset, " // -> ${text}")
		}
	}
}

line 24, I guess it should be result.toString() instead of 'asString(result)'
