Satire Development Kit: Democrats Use Groovy To Pick Candidate
This is our first SDK: a Satire Development Kit that allows you, dear reader, to create your own satire, tailored to your own taste.
In this case: political taste. And we'll will learn a bit of Groovy along the way.
Architecture
The SDK is based on these steps:
- No matter where you may lie on the political spectrum, you may agree that the process to pick the next Democratic presidential candidate (in the USA) is complex. It involves a mix of delegates and super-delegates.
- Groovy is apolitical, but uses delegates to resolve references in closures. Since delegates may be objects, they may be derived from other objects, which we'll dub super-delegates.
- Punchline: this is up to you. We just provide the tools.
Minimalist Example
class Foo {
def bar() { println "hello" }
}
def c = { bar(); }
c.delegate = new Foo() // delegate is a keyword
def candidates = [ "Clinton", "Obama" ]
candidates.each( c )
In the above example:
candidates
is an array that has a closure,c
, applied to each element- the closure calls
bar()
- Groovy will search for
bar()
, first in the owning scope ofc
(the script itself), and then, if necessary, inc
'sdelegate
- Groovy will not find
bar()
in the owning scope, but does find it in thedelegate
, which we assigned as aFoo
Full Example
Below, we have a full example where a self-named
Delegate
object acts as the, well, delegate and derives from the SuperDelegate
, which can pledge (or not?) for a candidate.
class SuperDelegate {
def clintonPunchline = "TODO: fill in"
def obamaPunchline = "TODO: fill in"
def pledge(def candidate) {
if( candidate == "Clinton" ) {
println clintonPunchline
} else if ( candidate == "Obama" ) {
println obamaPunchline
}
}
}
class Delegate extends SuperDelegate {
// defer to base class
}
def convention = { it -> pledge(it); }
convention.delegate = new Delegate()
def candidates = [ "Clinton", "Obama" ]
candidates.each( convention )
The Upshot
Simply fill in the punchlines in the above Groovy script, and you're all set to lampoon (or support) one of the Democratic nominees -- or both -- via a dynamic language on the JVM. The direction of your satire is up to you. Impress friends and family no matter if you are a Democrat, Republican, independent, or international observer.
Enjoy!

actually, it should be
class SuperDelegate extends Delegate
