I believe the command that you are looking for is: %> chuck ^ This prints the internal shred start at the listener VM, something like: [chuck](VM): status (now == 0h:2m:34s) ... [shred id]: 1 [source]: foo.ck [sporked]: 21.43s ago [shred id]: 2 [source]: bar.ck [sporked]: 28.37s ago (From: http://chuck.cs.princeton.edu/doc/program/otfp.html) I am doing something similar in Perl, so perhaps I can help you out. You can have your python script run this command on the shell (what OS are you running?) and grab the results (shred id, filename, etc) within that script. In Perl, it is done with the following code: @cmd_output = `chuck ^`; Then you can parse out the id number and run the following commands from the script to: Remove a shred ID: %> chuck - $shred_id _or_ Add: %> chuck + $shred_id _or_ Replace: %> chuck = $shred_id In Perl, assuming the above status output, the whole thing would look something like: # Get output from the chuck status command @cmd_output = `chuck ^`; # Parse IDs into shred_ids array @shred_ids = grep { /shred id\]:\s(\d+)\s/; $_ = $1 } @cmd_output; # Remove shred ID 1 (which is in the first array element) from the VM `chuck - $shred_ids[0]`; I hope this helps! -Dan >>> x(a)branwelt.de 04/07/06 6:24 AM >>> Hello I want to write a python program, that adds and removes (sporks) chuck-shreds to/from the chuck VM How to retrieve the shred-id ?

update 1.2.0.5b
by Ge Wang 06 Apr '06

06 Apr '06

Hi! There is now a patched version of 1.2.0.5, which fixes issues with 'adc' UGen. Going to multichannel introduced a bug where adc first output a buffer of random values. Also the latency is now slightly better. If you are doing anything with 'adc', you should probably get the newest 1.2.0.5b: http://chuck.cs.princeton.edu/release/ Thanks and Sorry! Best, Ge!

I must be missing something
by Eric Gilbert 05 Apr '06

05 Apr '06

Hi, I want to use ChucK to control a bunch of MP3 files according to GPS data for a project that I am doing. However, I cannot seem to get sndbuf to open anything. I converted my MP3 files to WAV and AIFF (both of which look to be supported) with LAME, but still no luck. What am I missing?

miniAudicle: MAUI controls
by Mike McGonagle 02 Apr '06

02 Apr '06

Spencer, I was reading more about the MAUI stuff, and this sounds great. I was thinking and had a couple of questions and suggestions. Are you thinking about how these interfaces can be grouped into functional windows? It appear that currently there is a window for every control generated, and if some code gets executed twice, there are actually two controls for a single variable. Also, have you ever seen Ceceila ( http://cecilia.sourceforge.net/ )? It is a front end for CSound. One of the things that they have that is really nice is the ability to create Graphs, and each line in the graph represents a different variable to control. Having something like this would be extremely useful, especially when you are dealing with a lot of variables and controlling them over time.

ChucK on Intel Mac

Hi, I just tried to build ChucK on my MacBook Pro. It did not build. Is there some executable out there for intel macs? Or a tweak to the source or the build process? Thanks, Eric -- "Tyranny is tyranny, let it come from whom it may." -- Revolutionary conscripts, 1776

Class Libraries, File Naming Conventions, and 'machine.add(...)'
by Mike McGonagle 30 Mar '06

30 Mar '06

Wow, Since the release of 1.2.0.5, I have been working with miniAudicle, and I really like what I see so far (up to this point, I had been using the commandline version of ChucK). So, I am not sure if there is a separate email list for the miniAudicle, or if I should send the email here, or to the Audicle list... so... One thing that I am trying to do is set up my Class Libraries in a fashion where I point miniAudicle to the root directory, and I put my stuff into a directory structure as follows: Package/ClassLibrary/Make.ck Where 'Package' represents a folder of my libraries, 'ClassLibrary' is the name of the particular library, and the 'Make.ck' file is used to load the individual library files in the order needed by calling 'machine.add(...)' on each of the files. In doing this, I was hoping to be able to enter the following in my program file so that the Mask library gets loaded: machine.add("mjm/Mask/Make.ck"); So, this works when I have just this line in a file, and all the class files get loaded in the proper order. BUT, once I put any additional code into this file, it will not load the class files at all (and this was after restarting the miniAudicle to ensure that there wasn't any conflict with previously loaded classes). Here are the issues that I see so far... (1) Would it be possible to allow for miniAudicle to have multiple paths that it would search for finding these libraries? (2) Am I using 'machine.add(...)' for its intended purpose (in loading classes)? Might there be a good reason to add another 'machine.load(...)' that does the same thing as 'add', except it does not spork a new shread for each call? This 'load' function could also be made to keep track of what files have been loaded, and any time there is a file that gets loaded more than once, any subsequent loads could just be ignored? (This might also change the miniAudicle interfact to include a button to load, in addition to the other buttons.) Would this function be best named 'load'/'include'/'import'? Which one? (3) Any thoughts on why the classes do not load when I have subsequent code in my program (after the 'machine.add')? I could send you an example of what I am trying to do, but this would require sending out my libraries, and I would prefer to sent those out as archives so that the directory structure is maintained.
