different send/receive behaviour on cvs version of PD
by stotz 20 Mar '03

20 Mar '03

hi miller & developers i just came across a problem when using the latest CVS-version of PD. unlike in the offcial 0.36-0 version, "send" and "receive" take a "set"-message to change their argument. though this is generally a good thing, it leads to quite a few problems with my old patches. (for example, i often send "set"-messages to sliders remotely, so they change their state without sending output. with the new version of send/receive i would change the remote names with the "set" message ...) what about something like "setname" instead ? ciao oliver

externals with OSX project builder
by Thomas Grill 19 Mar '03

19 Mar '03

Hi OSXers, has anyone tried and succeeded compiling pd externals with the Apple project builder? I'm clueless right in the beginning which target to choose (framework, bundle, etc...?)... no typical shared library here.... thanks for any pointers, Thomas

Re: [PD-dev] AppleScript to make PD double-clicker

On the other hand, it would not be a difficult >thing in your distribution to setup these standard locations. Well, it would be nice to do this in a way where scripts across platform can take advantage of it. I was imagining a couple files (named ".EXTERNALS" and ".HELP", I suppose) along the lines of: .EXTERNALS: location: ./vasp vasp pd/*.pd .HELP: location: . pd-help/*.pd The first line gives the destination location (in relation to the pd/ extras or doc/5.reference) directory, and the following lines give the locations of the files to be moved. (I suppose default .pd_linux, .dll, etc. suffixes should be omitted.) Is this any more useful than "install" rules in a makefile? I think so, but it might seem like a marginal difference at first. Unlike many install rules, this doesn't assume anything about absolute paths (or even relative paths--some rules for externals make assumptions about which directory the external is *made* in). Is this sort of explicit marking needed? I think so. I did some mini- experiments, to see if it was possible to guess the difference between help files and abstractions. It's really hard, even with a human in the loop, sometimes. Thoughts? adam -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Adam T.

AppleScript to make PD double-clicker
by Hans-Christoph Steiner 19 Mar '03

Has anyone tried to use AppleScript to write a nice double-clicker for PD on MacOS X? Someone suggested this approach to me but I have never used AppleScript. .hc zen \ \ \[D[D[D[D

GEM scale vs. maxlib scale workaround
by Hans-Christoph Steiner 18 Mar '03

18 Mar '03

Well, since it seems that this issue has stalemated, I thought I'd suggest a workaround idea: maybe we could make maxlib's scale also respond to 'range' and GEM's scale also respond to 'gemscale'. Then it would be easier to use both, like I would like to. just a thought... .hc zen \ \ \[D[D[D[D

Re: [PD] flext external problem
by Thomas Grill 18 Mar '03

18 Mar '03

Hi Tim, i think i know the problem. It's possibly badly documented but unfortunately the class name is of importance for the FLEXT_NEW statement. If you have a class "tbroute" then FLEXT_NEW generates a setup function named "tbroute_setup", while FLEXT_NEW_DSP generates "tbroute_tilde_setup". In your case of a class "tbroute_tilde" the latter would result in "tbroute_tilde_tilde_setup" which is not what PD wants. sorry for that and best greetings, Thomas ----- Original Message ----- From: <TimBlechmann(a)gmx.net> To: "Thomas Grill" <t.grill(a)gmx.net> Cc: <pd-list(a)iem.kug.ac.at> Sent: Tuesday, March 18, 2003 8:45 PM Subject: Re: [PD] flext external problem > thanks for your message, i used FLEXT_NEW_DSP_1 since i need a creation > argument. > i had the problem with both ~ and _tilde... > > i've attached the code, it would be very nice if you have a look at it. > thanks.. > > tim > > > Hi Tim, > > i would need to see the source to give you really concise information, but > > i > > guess there is a mismatch of message and tilde definitions here. > > > > Are you correctly using FLEXT_NEW_DSP* (instead of FLEXT_NEW*) in your > > signal external? > > You should also call your external tbroute~.pd_linux instead of > > tbroute_tilde.pd_linux.

[GEM] rendering context (gem2pdp)
by Tom Schouten 17 Mar '03

17 Mar '03

hi all i was wondering if it is possible (and how) to change the rendering context in gem, with respect to interfacing it to pdp (or something else) without gem using it's own display window. what i am interested in is having gem render to an offscreen area (pbuffer) and output this as a pdp packet. it is possible to use pbuffers and disable the window context entirely, but it seems it requires rather a large cut in gem. maybe i'm not seeing this correctly but i think it would involve something like this: * GemWinCreateXWin needs to be replaced by something that constructs a pbuffer instead of a window. * the place where the buffers are swapped: glutSwapBuffers() in GemMan.cpp a glReadPixels should be inserted that converts the data in the pbuffer to a pdp packet. * the glXMakeCurrent(constInfo.dpy, constInfo.win, constInfo.context) in GemMan.cpp should be replaced by a glXMakeContextCurrent(dpy, pbuffer, pbuffer, context_pbuffer) call. anyone any thoughts on this? tom

shell scripting in an install
by Adam Lindsay 14 Mar '03

14 Mar '03

Hi folks. I just wanted to do a sanity check for the postinstall script in my proposed MacOSX installer. It attempts to give a .tcshrc and .pdrc to those who don't already have them. Please, no flames about tcsh--it's still the default shell in MacOSX to the best of my knowledge, and it's the shell I know best. The intention is to prep the command line for those who don't like to use it, but to be kind enough to people who are able to hack their own dotfiles (and not clobber anything too important, which is why everything is an append). Comments before I turn this into a package? #!/bin/tcsh # root/realtime trick /usr/sbin/chown root /usr/local/pd/bin/pd /bin/chmod 4755 /usr/local/pd/bin/pd # make a few home/Library directories for future expansion /bin/mkdir -p $HOME/Library/Pd/Help /bin/mkdir $HOME/Library/Pd/Externals /bin/mkdir $HOME/Library/Pd/AdditionalDocumentation # add a path if ( ! `grep -sc /usr/local/pd/bin $HOME/.tcshrc` ) echo 'set path = ( / usr/local/pd/bin $path )' >>! $HOME/.tcshrc echo -rt >>! $HOME/.pdrc echo -path ~/Library/Pd/Externals >> $HOME/.pdrc echo -helppath ~/Library/Pd/Externals >> $HOME/.pdrc echo -path /Library/Pd/Externals >> $HOME/.pdrc echo -helppath /Library/Pd/Externals >> $HOME/.pdrc echo -guishadow >> $HOME/.pdrc echo -cordcolor >> $HOME/.pdrc -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Adam T.

flext and visuals
by bbogart 14 Mar '03

14 Mar '03

Hey all, what is the best way to write a cross-platform video and audio external? (all OSs under MAX JMAX PD) Does flext give some API to machine specific video/audio?) Will be starting a project to develop a video/data/audio streaming system over multicast, and ideally it would run on all the object systems above... thoughts? Ben

jack connect startup option
by Frank Barknecht 13 Mar '03

13 Mar '03

Hallo, I sometimes have problems starting complex patches on Linux with Jack without killing or time-outing the jack daemon. This gets worse, when trying to run with 4 in- and outchannels. I looked into the source (cvs), and currently Pd tries to connect all ports immediatly. I'd prefer, if that was configurable, like, for example having a startup option "-(no)jackconnect". What do you think? As a workaround, I added a "return 0" at the top of the jack_connect function in s_linux.c and connect by hand/script. ciao -- Frank Barknecht _ ______footils.org__
