tracking bugs
by Kassen 13 Sep '09

13 Sep '09

Fellow ChucKists, I made a start adding the open bugs here http://wiki.cs.princeton.edu/index.php/ChucK/Bugs/Release I added these from memory and by searching the list archives, there are likely more. I'm sure the DEV's also have their own list but I feel a open list, accessible to both the developers and to bug hunters will help clear up what are known issues to users as well as help create a "to do list". If anyone has favourite bugs to add, please do. We slacked on this a bit, in recent times. Yours, Kas.

Issue with chuck otf command on Windows Vista
by K． HIROKAZU 12 Sep '09

12 Sep '09

Hi, I have a problem with chuck command on Windows Vista Home Premium (32bit). After running a chuck vm in loop mode, adding any shreds lead to the folloing error message dialogue. === chuck.exe has stopped working A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available. === The following is the output to stderr when running command "chuck --verbose10 + sample.ck". === [chuck]:(2:SYSTEM): setting log level to : 10 (ALL!!)... [chuck]:(5:INFORM): examining otf command '+'... [chuck]:(5:INFORM): otf connect: 127.0.0.1:8888 [chuck]:(5:INFORM): | sending file:args 'sample.ck' for add...

Note that running a chuck vm with some shreds directly specified (e.g. chuck sample.ck sample2.ck) has no problem, and on-the-fly operations on miniAudicle 0.1.3.7 work well on Vista.

"make" not compiling -- Snow Leopard
by Andrew C. Smith 11 Sep '09

11 Sep '09

Don't really know who to turn to here, so I'm coming to you. I used to be able to very easily compile ChucK (plus the mini in a recent post) but "make" doesn't seem to be working for me now that I've got Snow Leopard. Would the new OS override or delete some previous compiler? Related but sort of unrelated question: why won't the xcode project for ChucK work? I get an error that it's missing its project.pbxproj file. But if there's a chuck.xcode file, it would seem that someone somewhere is building ChucK with xcode. Any takers or either of these? This is sort of an either/or question--if you fix one of my problems then I'll stop caring about the other one. Andrew

Re: [chuck-users] chuck shell... --> My vim usage
by Bill Nye 11 Sep '09

11 Sep '09

> From: kurt <sobrilliant(a)gmail.com> > I like the Mini but I really like Vim. That is > really the only reason I use the shell. When I heard mention of vim I thought I would share what I use to test chuck code snippets, directly from inside vim. To get alignment, be sure to view the following with a fixed-width font. It consists of one bash script, a symbolic link, and, on Win, a .bat file. In the main bash script below, the second 'cat' line returns the same stdin chuck code lines back into vim, followed then by chuck's stdout. (Of course, you also hear the chuck output, if any.) I'm sorry to say that after days of trying, I could not get chuck to play, and also deliver its stdout in just one invocation, hence the two chuck.exe lines. FILE ~/bin/chuck_execution_in_vi (Win version) #! /bin/bash # chuck_execution_in_vi -- Typically used in vi as: # :'a,.!chu to leave original lines and also # return Chuck execution output. tmp="/tmp/tmp.chu.ck.$$" cat > $tmp cat $tmp cmd /c start "`cygpath -w ~/bin/chuck.exe`" $tmp "`cygpath -w ~/bin/chuck.exe`" --silent $tmp \ 2>&1 | tr -d '\015' rm -f $tmp exit TESTS: Sit on next line in vim and type :.!chu <<< "Hello" >>>; You should see in vim after the '<<<' code line: "Hello" : (string) Sit on 'now' line and type :-,.!chu SinOsc s => dac; 1::second => now; FILE ~/bin/chuck_execution_in_vi (Mac version) #! /bin/bash # chuck_execution_in_vi tmp="/tmp/tmp.chu.ck.$$" cat > $tmp cat $tmp chuck $tmp 2>&1 rm -f $tmp On Mac and Win (cygwin) I have this symbolic link to cut down on typing: ~/bin/chu -> ~/bin/chuck_execution_in_vi On Win, I also need this parallel .bat file: (I set the 2 env vars in my .profile) FILE ~/bin/chu.bat @ECHO OFF PATH %WPROGRAMS%\cygwin\bin;%PATH% %WPROGRAMS%\cygwin\bin\bash %WHOME%\bin\chu %1 %2 %3 %4 %5 %6 %7 %8 %9 Of course, this only works well if the chuck code terminates on its own. I don't know what this can do for --loop or shreds but it may give you some ideas. Incidentally, on both Mac and Win I have QuicKeys, so I just do 'ma' (to mark the snippet beginning) move to the end, and type Ctrl-Shift-C , which simply types :'a,.!chu for me. -Bill

Problems compiling and running ChucK on Arch Linux
by Sean Sawyer 11 Sep '09

11 Sep '09

Hi, I'm a ChucK newbie running on Arch Linux (gcc 4.4.1, libsndfile 1.0.20, ALSA 1.0.20, flex 2.5.35, bison 2.4.1, make 3.81). When compiling ChucK, g++ complains that the function sprintf is undeclared in util_string.cpp. Sure enough, stdio.h is not included in util_string.h (or in chuck_def.h). After adding the following line to either util_string.h or chuck_def.h, ChucK compiles successfully - but I then get seg faults when running simple example code (e.g., examples/moe.ck). Any ideas? Verbose output from ChucK leading up to the seg fault is below.

static function overloading
by Kassen 08 Sep '09

08 Sep '09

Fellow ChucKists, Is there a reason why static functions can't be overloaded when the class they are a member of is extended? i don't (yet?) see why this would need to be so and it seems limiting. Yours, Kas.

The ChucK Show
by Les Hall 07 Sep '09

07 Sep '09

Hi folks, Last week on The Game Show we had plenty of ChucK. It was a hilarious time and we all enjoyed it. Next week: PLOrk and beans again! PLOrk as we all know is the Princeton Laptop Orchestra, and beans are the various ChucKists who contribute code. We'll have some most excellent music by Ben Zimmerman and a really good rendition of "Iron Man" by appleseedj and myself. Should be worth a listen at 7pm EST this Friday on www.electro-music.com radio. See you then! Les

One bit ChucK
by Hans Aberg 06 Sep '09

06 Sep '09

Have you discussed giving ChucK a 1-bit audio model? See for example: http://img3.harmony-central.com/Video/aes121/Korg_1-Bit_Recording_tutorial.… http://digitalmedia.oreilly.com/pub/a/oreilly/digitalmedia/2007/08/02/revie… It is essentially a raw format for audio. So it might help taking out those rough edges in the preprocessing. Hans

Good Moog, bad error (bug)
by Kassen 04 Sep '09

04 Sep '09

Dear list, Right now I'm having lots of fun with the Moog UGen, but when we mistakenly give it parameters out of range then the resulting error message is incorrect and potentially confusing; consider; Moog bob; 1.1 => bob.filterQ; this will give us; [chuck](via STK): Moog: Control value greater than 128.0! Yours, Kas.
