can i somehow set a startpath for [openpanel]?
by Roman Haefeli 03 Sep '04

03 Sep '04

hi if you have several [openpanel]s in a patch, everyone for loading files from a separate folder, it could be quite 'search-intensive' to load different files, because you always have to go in the rigth folder first. is there a solution for this problem like setting a startpath? by the way something else from my wishlist: an option in [openpanel] to set a suffix for a filetype to be visible in the opendialog would be great...... cheers roman

pdp 0.13 update
by Tom Schouten 02 Sep '04

02 Sep '04

hi all, last release was a joke. really. from now on it's serious. thanks to aymeric, rama, yves & artem for testing. pdp 0.13 is an unstable intermediate release based on packet forth (libtile/libpdp). if you use pd/pdp/pidip to make a living, stick with 0.12 for a while. especially libtile (the image processing engine) is still very experimental. gemheads, see at the bottom of the page. stuff below is a lotta verbose yada. PF the only real extra feature 0.13 brings is packet forth. packet forth (pf) is like mole, only more highlevel. a forth interpreter working with packets (and strings and network streams and other subprocesses etc...) pf's core (packets + forth interpreter) is now reasonably stable. it's been a while since i found a bug there, but there are still a whole lot of small bugs in the modules. i'm hunting them down atm. major pain is that 3dp (opengl drawing) still does not work. DOC one thing you can do with the forth is to write pd objects that can communicate with other pd/pdp/pidip objects. in the same spirit as Thomas' py/pyext objects for python. the advantage of pf is that the language is tailored for real-time use, python is not. it also has support for video, audio (there are dsp2pdp~ and pdp@dsp objects that enable you to convert audio streams to pdp vector packets) and other data types. vectors can be operated on using matrix operations and other functions from gsl. yeah, it's just the old pdp in a new jacket. the disadvantage is that pf is of course a forth, and not even a standard forth. now pf is linked to guile already, and a link to python will hopefully happen soon after most of the bugs for the current features are fixed, so there is hope. i'm working on some docs to explain how to get started. this is in doc/pf.xml (convert this to html using 'xmlto xhtml pf.xml'). it's pretty raw. to see some example objects written in pf, have a look at the files in /usr/local/lib/pdp/script/puredata these can be loaded in pd with [pdp <name>] you can load an arbitrary script with [pf <filename>] 3dp works like this too [3dp <object>], but is not working atm. eventually, i plan to write a whole lot of extra pdp modules, there is a lot of functionality in pf which just needs to be combined and exported as pdp modules. there's not much of them right now, because the language has been continuously in flux, breaking everything again. in 0.14 it will be frozen and backward compatible. the pdp 0.12 api (which pidip uses) will remain there until the end of the fishing season. BUILD last week i kicked out the autotools and replaced them with a very small perl script. most of the configure&build process is the same as it was before, only that libpdp is now 2-pass (libpdp compile+install and pf+plugins compile+install). to do this in one go, use make all_install after running (./bootstrap and) ./configure in the libpdp dir. this builds and installs libpdp and the plugins. by default all the plugins try to build, and only those that succeed will be installed. this seems like the least hassle. it's very straightforward. each plugin needs its set of libraries. most is the same as pdp 0.12.x if something fails, you can check build/build.log for details. all the error messages of the build are dumped there. most build problems seem to be fixed now. if you encounter any, please email me the build.log file. CVS distribution is still CVS only. see http://zwizwa.fartit.com/pd/pdp/doc/ for details. GCC small note on libtile (small virtual machine for image tile processing). this makes extensive use of some gcc vector extensions and agressive inlining and optimization. some versions of gcc seem to choke on this. i use gcc.real (GCC) 3.3.4 (Debian 1:3.3.4-6sarge1) which seems to work, but i had to navigate around a bug. problems are reported with these versions: 3.2.2 (crashes, or at least runs into some inconsistency) 3.3.3 warning: can't inline 3.4.? warning: can't inline i didn't find a pattern yet. this sucks, i know, and i'm trying to find a workaround. the -Werror flag is removed so it at least builds. 'can't inline' in libtile really is an error, since inlining is the whole point of libtile ('codelets'). FINK & CYGWIN i tried to build libpdp on OSX/fink, which works for the most part. but since libtile does not work yet, there's not too much you can do with it. same for cygwin. compiling the core seems to pose no problems. i think the rest has been done by carmen (pdp base library). so, a windows port is definitely in reach. now somebody needs to just do it (write native input/output modules). GEM for the platform-dependent stuff it might be wise to start piggybacking on GEM, a kind advice i've been ignoring for a while. seriously, talking about gem. i think the moment has come to connect a headless pf (libpdp) to gem. this should be really straightforward. the only thing i'd need is a point in the control flow, where i can execute some opengl statements in the current context. then in a later step all the data types (and processors?) of GEM could be mapped to pf's or wrapped as abstract data types, intertwining them a bit more. this would lead to a situation where 'the user' could choose an interface or a policy or hair style (gem or pdp) and all the functionality would be available. pf uses pdp/pidip's data format, so when pf is connected to gem, pdp/pidip is too. (livido will come soon). that should be enough pf promo for today. as usual, if you encounter a problem, don't hesitate to report it. cheers, tom

Data structure arrays: plotting and editing "w"
by Frank Barknecht 02 Sep '04

02 Sep '04

Hi, when plotting an array using [plot] there are three variables treated special in array element templates: x, y and w. Now if I use the w to let the line width change, I'm not able to change the y-position of an element with the mouse anymore. This is on Linux. I still can change y using "set" objects, though. Is there a way to design my templates, so that y stays mouse-editable as well? I attached an example patch, which should show this behaviour (w.pd). Ciao -- Frank Barknecht _ ______footils.org__

pd fileformat another
by marius schebella 31 Aug '04

31 Aug '04

Hi, I am looking for a way to dynamically replace text (comments,...) in Pd patches. For instance I want to add a comment, let's say an URL or a copyright note to all my patches, and have the text saved in a seperate textfile. So if the URL changes I would not have to change all the patches, but only the textfile. In a future step I am thinking of a Pd file format like html, where parts of the patch could interact with mysql databases or be written in python or javascript, like webpages. Are there any plans to have such kind of patch coding in the future? Or has someone already written an application like a Pd-file generator to convert whatever to pd-style format? marius.

Pure Data Trigger Gang Bang - preview
by aym3ric 30 Aug '04

30 Aug '04

Dear PD fans, i'm very glad to announce you an event that will certainly change the face of earth. For the first time ever a Pure Data demo online contest is organized. Right now this mail is just an announce preview as the official start will occur in the upcoming week. Everyone is encouraged to participate, no winners, just a friendly gathering of compos patchers. Once all the patches are received they will be published by goto10 (tempsite@: http://goto10.org) an .fr non-profit org dedicated to digital arts support. ------------------------------------------------------------------------ To participate you just have to follow a couple of rules (hey it's a compo contest ^^). - patch type : fully automated/scheduled/generative NO INTERACTION - content : audio AND video (choose your favourite weapon PDP/PiDiP, Gem, Framestein, GridFlow) - size : patch(es) + extra material must NOT exceed 128kB - externals : ONLY the ones from CVS - application : anyone can apply, individual and teams AND several times !!! - net : the use of internet is tolerated as long as you don't use [shell] to download 300MB of porn files. (mmm? well let's say that one could use [shell]+some perl to grab stuff from google, but on the other hand it would be forbidden to use [shell]+wget to grab from your www/ftp all the material you needed for your patch that woud not fit in 128kB). - CPU/GPU : no real limitations, just consider that if your patch takes 100% of the CPU of your brand new box you just bought to play DoomIII then you should be aware that some people could have trouble to run your patch. - OS : use your own. no restricitions ;) - theme/style : no theme or style, everything is most welcome ! from oldskool flexiscolls and soundchip trackers to pure noise abstractions. - deadline : you can start to send your patch(es) the 1st of september until the 20th of september, then all the patches will be published on the PD Trigger Gang Bang Site. ----------------------------------------------------------------------- feel free to mail me if you have any questions official announce mail + Gem flyer available soon. if you only make audio patches and want to participate, it should not be hard to find someone for the visual part on the pd-list ;) +! aym3ric.

play midi file
by Christian Klotz 30 Aug '04

30 Aug '04

hi all, it seemed to me a simple thing to play a midi file. But I didnt get it to work. I read something about the xeq lib, but I didnt find any mac os x binary and compiling aborted with make: *** [../shared/hyphen.o] Error 1 rm xeq_follow.o xeq_polyparse.o ../shared/bifi.o xeq_parse.o ../shared/mifi.o ../shared/mfbb.o ../shared/sq.o xeq_time.o xeq_query.o xeq_data.o ../shared/dict.o xeq_host.o xeq_record.o xeq_polytempo.o So the patch included in the doc in the playnow folder wont work. any idea how to get midi playback working? thx in advance --- Christian Klotz Kunsthochschule Kassel / School of Arts Kassel ::digitalpool
