Ah, I see! I agree it's much nicer if ChucK is forgiving in the examples you showed :-) cheers, Casper

Yep, as Tom says. We couldn't have our language throw an error on float temp; for obvious reasons. Scoping is one of the wonderful parts about such languages.

Should it not be simply forbidden to redefine a variable like that in a sub-class ? When you assign instead of declare, the problem disappears. So perhaps, instead of 'fixing' the bug, we should forbid this kind of use of scope (chuck should throw an error if you try) ? Casper class A { 10000 => int foo; } class B extends A { fun void bar() { // 0 => int foo; 0 => foo; <<< "a", foo >>>; { <<< "b", foo >>>; } <<< "c", foo >>>; } } B b; b.bar(); Casper Schipper casper.schipper(a)gmail.com www.casperschipper.nl +316 52322590

Scope bug?
by Ian South-Dickinson 07 Aug '14

07 Aug '14

I encountered a strange case where a variable was changing value within the scope of an if statement, because I had a superclass with an identical variable name. I am able to reproduce it with this simple case: class A { 10000 => int foo; } class B extends A { fun void bar() { 0 => int foo; <<< "a", foo >>>; { <<< "b", foo >>>; } <<< "c", foo >>>; } } Prints out: a 0 b 10000 c 0

Thanks for your help, Joel - and Spencer. :) I think I need some extra software for compiling ChucK - I'll look into it. I have a more recent Intel Mac laptop, but the thing about the G5 is it has the PCI slots for my MOTU 24io. I would need to get another interface to use ChucK on the laptop. I could pick up an eight channel USB MOTU fairly cheaply.

Hello Joel, thanks for the fast reply. Yes, it's a PPC machine.

Installing on OSX 10.5.4
by Tom Charles-Edwards 05 Aug '14

Hello, first post here. Looking forward to learning ChucK. :) I have a G5 running OSX 10.5.4. The current version of ChucK is apparently good for 10.5 and later. Tried that - didn't work. I see all the older versions on a separate page. Which one should I try? Thanks for any help, Tom

Any way to use .pos passing a string?
by Federico Lopez 17 Jul '14

17 Jul '14

Hi, I have an array of strings (p1) that contains the same names of SndBuff instances (kk sn), I would like to pass the strings of the array to trigger samples and I don't know how to do it. Here is some test code: SndBuf kk => dac; SndBuf sn => dac; me.dir() + "/audio/kick_01.wav" => kk.read; me.dir() + "/audio/snare_01.wav" => sn.read; kk.samples() => kk.pos; sn.samples() => sn.pos; while( true ) { ["kk", "sn"] @=> string p1[]; for( 0 => int i; i < p1.cap(); i++) { 0 => p1[i].pos; // not working 0.25::second => now; } } Thanks, Federico López
