Re: [chuck-users] how to mickey-mouse a 'switch' statement into chuck?

Doing functional stuff in ChucK can be pretty fun (and verbose), but for specifically switch-case structures, mostly these can be implemented e.g. as if(var == 0) // case 0: { } else if(var == 1) // case 1: { } else // default: { } You can't do fall-throughs or nutty things like Duff's device, but (making up a number) maybe 90% of switch-case uses I see are basically a slightly better-looking if-else. Are you doing something more elaborate than branching on the value of a specific variable? spencer On Mon, Oct 12, 2015 at 2:22 PM, Forrest Curo wrote:

It looks far prettier than a mess of logical spaghetti!

But is this documented with examples for the help & understanding of object-challenged geezers from the days of punch-card boxes converted twice/day to error-message listings?

Since switches have so far not been included, is there a way around this?

An array of Events?

An array of functions, either numbered or associative? How to declare and call such an array?

ChucK doesn't have function pointers or similar, so I've resorted to functors

https://github.com/heuermh/lick/blob/master/lick/fn

E.g.

class DoSomething extends Procedure { fun void run() { ... } } class DoSomethingElse extends Procedure { fun void run() { ... } }

DoSomething doSomething; DoSomethingElse doSomethingElse;

ArrayList procedures; procedures.add(doSomething); procedures.add(doSomethingElse);

while (true) { procedures.sample() $ Procedure @=> Procedure procedure; procedure.run(); 1::second => now; }

Yeah, it ain't pretty.
