Dev Meeting this Friday host IRC.FreeNode.Net port 6667 channel #dataflow time: |- 19.00 UTC+2 (Graz/etc) |- 17.00 UTC |- 13.00 UTC-4 (Montréal/NewYork/etc) `- 9.00 UTC-8 (SanDiego) reminder: summer time is in effect in Montréal and Graz. there is no such time shift for SanDiego, and we don't want Miller to have to get up too early, so this is why it's late for the europeans. Sorry. Drink your Murauer in front of the computer. (It rhymes so it must be a good idea) I'll _try_ to come up with the topic-list I have promised, ... well, before the actual meeting, anyway. ,-o---------o---------o---------o-. ,---. | | | The Diagram is the Program (TM) | | ,-o-------------o--------------o-. `-o-----------------------------o-' | | Mathieu Bouchard (Montréal QC) | | `---' `-o-- http://artengine.ca/matju -'

ogg bonus
by rama 25 May '05

25 May '05

oh, i also did oggcastw~ which is basically a merge between oggcast~ and oggwrite~ to be able to record independently from the stream despite network stability, to be sure that you can save to local file even if the net breaks (and you don't lose your session). you would say why not using both oggcast~ and oggwrite~, but this hacking came up from the need of our beloved hackmedialab in barcelona where they stream with a P IV 1.7 and using both objects would load the processor enough to have an ugly stream and recording. you can get it here: http://rama.xicnet.com/oggcastw~.tar.gz actually what do you think about the idea and also the possibilities of making an object which does the encoding, and then you can route this to the streamer or writer objects. the point should be to not encode twice the same data, for recording and streaming. would that be possible? does it make sense? hasta luego, r --

pdogg hacks
by rama 25 May '05

25 May '05

hi all -- first -- thanx tim and guenter for the help on my pd freezes with kernel 2.6 and bla. it seems to work now, but the bad thing is i wouldn't be able to tell what was really the problem. i will keep an eye on it, still need more testing -- now -- i've done some hacks to the pdogg lib from Olaf Matthes (Olaf: are you still around?) which have the following changelog: oggread~: v 0.2d (21 May 2005) - fixed segfault when trying to open or play wrong files and send EOF bang - added support to read ogg/vorbis metatags (id3 info) oggcast~: v 0.2m (21th May 2005) --by rama: - updated help-oggcast~.pd: now provides a valid streaming server/password to start (thanks r23.cc) - fixed segfaults while setting Vorbis Comments (id3 tags) - made description tag set-able through message (was hardcoded) - fixed lot of indentation chaos in the code i think this fixes are important and it's a very nice working lib in general and is great to expand the use of OGG. i would like very much to introduce this into the externals main repository. I've never used cvs, and this could be a fine point to start if you agree. i would even like more if any of you could review a bit the code. my C knowledge is very initial, and i could have done horrible things in this code, but what i can say is it works! :) it's published here: http://rama.xicnet.com/software/pdogg-0.26.tar.gz ps: i don't know if a diff would be helpful, as I've changed a lot the indentation, as the originial seemed to be quite messed up. have a nice evening! greetz rama --

renaming core help files to the standard name
by Hans-Christoph Steiner 25 May '05

25 May '05

I would like to rename the Pd core help files in CVS so that they conform to the naming convention *-help.pd. Currently, they are in the deprecated format help-*.pd. There are two ways for this to happen: add and remove the files from CVS, or put in a support request to sourceforge to have them rename them in CVS. The later option is preferred because then the CVS history is preserved. This script will rename the files for you if you run it in pd/doc: #------------ #!/bin/sh for helpfile in help-*.pd ; do mv "$helpfile" "`echo $helpfile | sed 's/^help\-$.*$\.pd$/\1-help.pd/'`" done #------------ Once we agree to this, I'll put in the SourceForge support request. It generally takes them less than a week to fulfill such requests. .hc ________________________________________________________________________ ____ "[W]e have invented the technology to eliminate scarcity, but we are deliberately throwing it away to benefit those who profit from scarcity." -John Gilmore

adding .pd_linux and .pd_darwin to cvsignore
by Hans-Christoph Steiner 25 May '05

25 May '05

So each CVS repository has a config file called CVSROOT/cvsignore. In there you can put file patterns that CVS should ignore (i.e. you won't get a "? zexy.pd_darwin" line when doing a "cvs update"). Things like *.o and *~ are automatically included. I would like to add *.pd_linux and *.pd_darwin to this list as well. If people think this would be generally useful and not cause problems, I'll commit it to the SourceForge repository, otherwise, I'll set it locally (~/.cvsignore). .hc ________________________________________________________________________ ____ Man has survived hitherto because he was too ignorant to know how to realize his wishes.

array locks
by Tim Blechmann 25 May '05

25 May '05

hi miller, since i have to rewrite the garray locks once again, can you estimate, when you will finish the implementation of the t_garrays? once again it's easier to rewrite them than porting ... it's similar for thomas grill's garray_update functions ... i'd suggest we try to meet on irc during the next few days (probably evening for me, morning for you :) to discuss if and how we can handle this ... i'd like to improve the threaded soundfiler soon, but without knowing what will happen to the t_garrays in future, its probably only a waste of my time ... usually, sitting at my computer i'm logged into the #dataflow irc channel, so it would be nice if you could try to contact me there ... thanks ... tim -- mailto:TimBlechmann@gmx.de ICQ: 96771783 http://www.mokabar.tk latest mp3: kMW.mp3 http://mattin.org/mp3.html latest cd: Goh Lee Kwang & Tim Blechmann: Drone http://www.geocities.com/gohleekwangtimblechmannduo/ After one look at this planet any visitor from outer space would say "I want to see the manager."

folder for tcl extensions
by Hans-Christoph Steiner 24 May '05

24 May '05

I just discovered that the Wish Shell.app already has a folder for putting tcl extensions in it: (from http://cvs.sourceforge.net/viewcvs.py/tktoolkit/tk/macosx/README? rev=1.12 ) * the standalone Wish has the directory Wish\ Shell.app/Contents/lib in its auto_path. Thus you can place tcl extensions in this directory (i.e. embed them in the app package) and load them with [package require]. .hc ________________________________________________________________________ ____ ¡El pueblo unido jamás será vencido!

introduction
by Anton Woldhek 24 May '05

24 May '05

Hi Everbody, Im Anton, Hans asked me to introduce myself because I was added to the sf pd dev team. Im a sound design student at the school for the arts utrecht. At the faculty Art, Media & Technology. I was introduced to programing with pd. I started using it somewhere in the fall of 2003 I believe. (The logs on pd-list could prove to be usefull for more exact historic evidence). In the last year or so ive have started coding in C++ also. Utrecht is a place in the Netherlands, which is also the region of my birth a mere 23 years ago. Currently im working on an art installation involving pd, 4 speakers and a phone called TEIT (working title) and a tape composition for 4 speakers. I was invited to join the sf team by Hans to work on some of the tutorials for PD. In later years I hope to bring some externals for pd, ofcourse when my C(++) & DSP skills have become kickass enough for this. Well, honored to be amongst such inspirational and inteligent people Anton Woldhek

Mac OS X Pd.app build fixes
by Hans-Christoph Steiner 24 May '05

24 May '05

After a long journey into obscure Mac OS X linking options, I finally figured out the build problem that Miller and I were having. I also included Jamie's renaming fix, and renamed "pdtcl" to "libPdTcl.dylib" following the Mac OS X standard. You can get the patch here: http://sourceforge.net/tracker/index.php? func=detail&aid=1204294&group_id=55736&atid=478072 I ended up with this bear of a linking target: > $(BIN_DIR)/libPdTcl.dylib: $(GOBJ) $(GSRC) > cd ../obj && $(CC) -dynamiclib -read_only_relocs warning \ > -o $(BIN_DIR)/libPdTcl.dylib $(GOBJ) \ > -F@TCLTK_FRAMEWORKS_PATH@ \ > -framework Tcl -framework Tk -framework System \ > -Wl,-install_name,@executable_path/../Resources/bin/libPdTcl.dylib > install_name_tool -change @TCLTK_FRAMEWORKS_PATH@/Tcl.framework/Versions/8.4/Tcl\ > @executable_path/../Frameworks/Tcl.framework/Versions/8.4/Tcl \ > -change @TCLTK_FRAMEWORKS_PATH@/Tk.framework/Versions/8.4/Tk \ > @executable_path/../Frameworks/Tk.framework/Versions/8.4/Tk \ > ../bin/libPdTcl.dylib With this patch, the preferred way to build the Pd.app is to install TclTkAqua.dmg version of your choice into the default location. (preferrably the newest, especially 8.4.7 or newer since it included Jamie's CG updates). So I am using TclTk-8.4.9 installed into /Library/Frameworks. On Tiger, TclTk 8.4.7 is installed into /System/Library/Frameworks. To build the Pd.app, run "make darwin_app_core" in "packages/darwin_app". Make sure a copy of "TclTkAquaStandalone-8.4.9.dmg" is in that same directory. The Makefile will pull all the files it needs from there. .hc ________________________________________________________________________ ____ "Looking at things from a more basic level, you can come up with a more direct solution...
