Groovy 2.0 comes with some amazing new features, which prompted a numbering scheme jump from 1.9.x to 2.0. One of the key features that I took note while going through\u00a0 Guillaume Laforge’s presentation at 33rd Degree <\/a> was the support for plain language sentences made possible by optional parentheses,\u00a0 and dots.<\/p>\n

We love the language and we love pizza! So, I put together a small script to demonstrate the power of natural language support available on Groovy 2.0 (Tested the feature on 2.0.0-beta2).<\/p>\n

The PizzaDelivery takes orders and outputs the order.<\/p>\n

[java]<\/p>\n

class PizzaDelivery {<\/p>\n

Integer quantity
\n String topping
\n Date time<\/p>\n

PizzaDelivery need(Integer quantity){
\n this.quantity = quantity
\n return this
\n }<\/p>\n

PizzaDelivery with(String topping){
\n this.topping = topping
\n return this
\n }<\/p>\n

PizzaDelivery at(String time) {
\n this.time = Date.parse(‘h:mm’, time)
\n return this
\n }<\/p>\n

String toString(){
\n return "${quantity} ${topping} at ${time.format(‘h:mm’)} hours"
\n }
\n}<\/p>\n

PizzaDelivery pizzaDelivery = new PizzaDelivery()
\npizzaDelivery.with{
\n need 3 with ‘pepperoni’ at ‘6:00’\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \/\/ need(3).with(‘pepperoni’).at("6:00")
\n}<\/p>\n

println pizzaDelivery<\/p>\n

[\/java]<\/p>\n

This will allow us to create very simple yet elegant DSLs which would feel like English or any other language that one feels comfortable with.<\/p>\n","protected":false},"excerpt":{"rendered":"
