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? Something else?

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. michael

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:

No. Without them chuck will complain when loading the import.ck file $ chuck + import.ck ... [TapeDelay.ck]:line(26): cannot extend incomplete type 'Swh' [TapeDelay.ck]:line(26): ...(note: the parent's declaration must preceed child's) [RubberBand.ck]:line(26): cannot extend incomplete type 'Ladspa' [RubberBand.ck]:line(26): ...(note: the parent's declaration must preceed child's) "LiCK imported." : (string) but everything else will work fine. And installing all of those plugins is a real mess, especially on OSX. I should probably cut a docker image at some point. michael

Hello Forrest, The import.ck script is a workaround for this issue Add namespaces and import statements #34 https://github.com/spencersalazar/chuck/issues/34 I believe many other ChucK projects use something similar. If you don't want to see plugin related warnings, you can just comment out from around line 387 down, and of course anything else you don't need. michael On Mon, Oct 12, 2015 at 10:34 PM, Forrest Curo wrote:

No. Without them chuck will complain when loading the import.ck file

$ chuck + import.ck ... [TapeDelay.ck]:line(26): cannot extend incomplete type 'Swh' [TapeDelay.ck]:line(26): ...(note: the parent's declaration must preceed child's) [RubberBand.ck]:line(26): cannot extend incomplete type 'Ladspa' [RubberBand.ck]:line(26): ...(note: the parent's declaration must preceed child's) "LiCK imported." : (string)

but everything else will work fine. And installing all of those plugins is a real mess, especially on OSX. I should probably cut a docker image at some point.

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?

New subject: how to mickey-mouse a 'switch' statement into chuck?

Hmmm! Then this would also work? [a tinkered-with example] -- (It doesn't appear that a chuck file absolutely _needs_ to end in '.ck', except for our convenience. So if I put in a file for each keyboard letter I would use....): " KBHit kb; // time-loop while( true ) { // wait on kbhit event kb => now; // potentially more than 1 key at a time while( kb.more() ) { // print key value machineadd(kb.getchar()); } } " On Tue, Oct 13, 2015 at 8:04 AM, Michael Heuer wrote:

Hello Forrest,

The import.ck script is a workaround for this issue

Add namespaces and import statements #34 https://github.com/spencersalazar/chuck/issues/34

I believe many other ChucK projects use something similar. If you don't want to see plugin related warnings, you can just comment out from around line 387 down, and of course anything else you don't need.

Okay, I finally found the documentation re usage... https://github.com/heuermh/lick/wiki

Shreds that just declare classes so that other shreds can instantiate & use them... It makes my mind blur, but so it goes!
