Renato, If you know the sizes of your vectors you could simply pass the elements of your vectors as separate arguments and populate the various arrays in chuck. The following makes two arrays -- one with two elements, one with three: chuck test.ck:1:2:3:4:5 test.ck as follows: int vect1[2]; int vect2[3]; for( 0 => int i; i < me.args(); i++) { //fill vect1 if(i == 0) { for( 0 => int i; i < vect1.cap(); i++) { Std.atoi(me.arg(i)) => vect1[i]; } } //fill vect2 if(i == 2) { for( 0 => int i; i < vect2.cap(); i++) { Std.atoi(me.arg(i+2)) => vect2[i]; } } } for(0 => int i; i < vect1.cap(); i++) { <<<"vect1", vect1[i]>>>; } for(0 => int i; i < vect2.cap(); i++) { <<<"vect2", vect2[i]>>>; } test.ck outputs: vect1 1 vect1 2 vect2 3 vect2 4 vect2 5

Hi Chuckists, chuck -s test:walk-sample:silence-rest:loop:ap-ppa-appp:3-1-2_1-2-3-4-5-7-6 test.ck is as follows: <<<me.args()>>>; for(0=>int i; i < me.args(); i++){ <<<i, me.arg(i)>>>; } and outputs: 5 :(int) 0 walk-sample 1 silence-rest 2 loop 3 01-001-1000 4 3-1-2_1-2-3-4-5-7-6 i undestand that ChucK has only atof and atoi to get values from incomming strings. and i but 01-001-1000 is/are three vectors: [0,1], [0,0,1] and [1,0,0,0]. and 3-1-2_1-2-3-4-5-7-6 is/are actually two vectors: [3,1,2] and [1,2,3,4,5,7,6]. the first arguments are stringed options passed to ChucK scripts, seems okay. i need these two separate ordered sets of vectors.. i am thinking of sending each value independently (test:.....:4:6:9......) separating each vector by, say, 999. and each set of vectors by 9999 any better idea?

Asio build (please?)
by Kassen 12 Aug '08

12 Aug '08

Fellow ChucKists, Would there perhaps be somebody who has some experience with building on Windows and who could spare the time to roll me and others like me a ASIO version of the latest& greatest? Perhaps somebody already has? I'd like to use the latest version but I'd also like the have decent latency on Windows, judging by the download stats on the forum (where the previous versions were hosted) there is a significant amount of interest in this; the last version (by Moudi) was downloaded 34 times, the version before that (by Philippe) 184 times, I'm not sure exactly how many ChucKists there are but I suspect those to be signifficant numbers. Eternal gratitude as well as a drink if/when/where we meet shall be yours. Cheers, Kas.

.size() fails to properly instantiate objects
by Kassen 10 Aug '08

10 Aug '08

Fellow ChucKists, Below you'll find some example code proving that extending a array of instances of a home-made class using ".size()"doesn't properly instantiates the new objects, leading to nullpointers and the shred being dropped. The "<<" operator, using "new" does lead to proper instantiation. I feel this is a bug. Yours, Kas. =====================8<============================== //instantiate a array of home made classes foo bar[1]; //check that this works <<<"your lucky number is ", bar[0].value>>>; //grow by one. bar << new foo ; //make sure it's instantiated <<<"your lucky number is ", bar[1].value>>>; //grow by a another one bar.size(bar.size() + 1); //make sure we did, size should now be 3 <<<"size is now", bar.size()>>>; //try to verify this is instantiated, it won't be <<<"your unlucky number is ", bar[2].value>>>; class foo { Std.rand2(0, 10) => int value; } ===================================================

pass arguments without the pesky colons
by N. Cameron Britt 10 Aug '08

10 Aug '08

Don't know if this is useful to anyone, but here's a little Perl script that allows you to pass arguments to Chuck separated by spaces rather than colons. Run this and let Perl run Chuck for you with properly formatted arguments. Should be in the same directory as the Chuck file you're trying to run. #!/usr/bin/perl my $args = join(":", @ARGV); $cmd = "chuck YOUR_CHUCK_FILE.ck" . ":$args"; #print "$cmd\n"; exec($cmd); Run with a command something like this: ./arg.pl arg1 arg2 arg3 etc I could imagine something like this being expanded into some sort of on the fly programming front end, to pass arrays of pitches for example.

me.numArgs() broken?
by N. Cameron Britt 06 Aug '08

06 Aug '08

Is me.numArgs() broken? This code taken from the concurency/shreds page of language specification: // print out all arguments for( int i; i < me.numArgs(); i++ ) <<< me.arg( i ) >>>; returns this error: "class 'Shred' has no member 'numArgs'"

Cool, I will :¬) The "ChucK => MIR programming" workshop at the upcoming > ISMIR already has 40 registrants; The user base seems to be growing > steadily. > Sounds great! Will more info on this "MIR" concept be available for the geographically challenged as well? I'm becoming really interested in analysis of incoming signals (not just audio but also patterns and structures in other forms of realtime input like HID) but this is hard stuff and any help would -well- help. :¬) Yours, Kas.

Re: [chuck-users] WiiMote Support
by Inventor-66＠comcast.net 26 Jul '08

Osculator does WiiMote to OSC (I've tried it on the Mac, wasn't too hard to get working), but maybe you want something built into ChucK itself? http://www.osculator.net /Stefan Stefan, Thanks, that's another piece of the puzzle, but yes I was looking for something built into ChucK itself. I will make do with Osculator as best as I can. I run into certain problems with external software like what version of OSX does it require. Oh? that means a $130 upgrade and a $100 disk, no I can't do that, etc... But soon I will have a Linux box and that will help things. Are there any plans to provide built-in ChucK support for the WiiMote and like devices? Les

WiiMote Support
by Inventor-66＠comcast.net 26 Jul '08

26 Jul '08

Hi folks, I know the DEV TEAM is overworked to the max with releases and features and bug fixes and all that jazz, but this is a thing that has already been started I think. There was supposed to be some exploration on Spencer's part perhaps of native ChucK WiiMote support, or so I heard. I was just wondering where that effort drifted off to. I am in need of a WiiMote solution for Mac and/or Linux. For Linux I can use nescivi's code so that's cool, but I dunno about mac. Any advice or web links? I just gotta swing my guitar like an axe and make cool sounds like that! Les

time and truth (bug?)
by Kassen 24 Jul '08

24 Jul '08

Dear list, Considering that this is valid; if (now) <<<"yay">>>; if (second) <<<"hurray">>>; I feel that this should be valid as well; if (now && true) <<<"this won't parse">>>; However, it isn't; ChucK complains the "&&" operator can't be resolved on time and int. This is a issue as well; if (second && true) <<<"This neither">>>; of course we could go... if (second) if (now) if (true) <<<"this is silly but runs">>>; ...but that looks a bit primitive. Yours, Kas.
