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

12 Oct 2015


      I'm gathering that I can just put 'machine.add(<any of these classes in the
directory that I want to use>)' and
that should work(?)

Okay, I did find the github zip for tap-plugins -- but the later plugins
are struggling; and I wasn't thinking of using them... so I'll assume that
I'm okay if I don't, for now.

To use a text keyboard to trigger real-time changes in key, mode
('major', 'minor', etc), record-&-repeat-&-vary (by scale degrees in
whichever the current  key & mode are), accelerate or slow playback, change
target instrument for playback-and/or-midi-keyboard, dump or keep current
loop, etc:
with some 36+ keys available for whatever organization of this works --
and I want to be able to modify the arrangement meanwhile so I don't
trap myself into a bad design...
so running the text input through a maze of logic by ascii values seems
too cumbersome.
I know, I could search-&-replace, but finding a key value in a list
and changing the associated function
just seems a whole lot less ugly!
-------------------------
Um, I'm now trying to install 'tap-plugins' as a prerequisite for
installing 'lick' -- and the instructions for that are telling me, ~'just
cd into folder and run 'make' -- but make can't find anything _to_ make! Do
I really need those plugins to install & use lick?
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?

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?

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.
