Hello,

I'd like to announce the release of MetaBuilder, a builder that builds
builders.

To learn more, please visit: http://groovytools.sourceforge.net/builder.

Here is a very quick example:

Say you have the following classes:

  class Invoice {
    def date
    def items = []
  }

  class Item {
    def upc
    def qty
    def price
  }

Here is how to MetaBuilder how to build Invoices:

    import groovytools.builder.*

    def mb = new MetaBuilder()
    def invoiceSchema = mb.define {
       invoice (factory: Invoice) {
          properties {
            date()
          }
          collections {
            items {
               item (factory: Item) {
                  properties {
                    upc()
                    price()
                    qty()
                  }
               }
            }
          }
       }
    }

Finally, here is how to actually build an Invoice:

    def anInvoice = mb.build {
       invoice(date: new Date()) {
          items {
            item(upc: 123, qty: 1, price: 14.99)
            item(upe: 234, qty: 4, price: 14.99)
            item(upc: 345, qty: 6, price: 14.99)
          }
       }
    }

    assert(anInvoice instanceof Invoice)

Enjoy!
