I have the inkling that if I could employ a full-time dev to do my bidding then Qt Quick would the "right way" to go-- it's in Debian, is cross-platform, well-documented, and it certainly has enough features for Pd's canvas editing. Actually 2 things come to mind: * Cairo <http://cairographics.org/> for rendering and something else like QT or a layer below tk for the chrome. We use cairo for pdf rendering in OpenFrameworks, among a few other things. * Juce <http://www.juce.com/>: It’s aimed at audio, cross platform, and Max has used it since Max 5. I used it at one place I worked and it can do quite alot actually. > But I don't know how to retrofit a c program like Pd with Qt, nor how to replace Pd's current string-based communication with whatever one is supposed to use to do that. I guess you don’t really retrofit the existing Pd, but rebuild it. Chris and I have done this with DroidParty & PdParty to some small degree using libpd. Sending messages and samples to and from the dsp engine is working. If that could be expanded to the requisite GUI calls, then bringing patch editing could be next. libpd currently has “sendFloat”, “sendSymbol” etc, off the top of my head we could add something like “createCanvas” which returns a canvas pointer, etc. In the case of libpd, you don’t communicate with the dsp engine over a socket but by function calls. Obviously you could use a socket and pass data along from a separate GUI which then calls the functions. I’m just musing here that it’d be nice to abstract the dsp graph, canvas, etc within libpd. That would at least make it possible to support patch creation and editing in PdParty, etc without rolling something myself. If did have to, I’d rather do it in a generic way inside libpd so Chris could use it DroidParty or I could add it to ofxPd, etc. -------- Dan Wilcox @danomatika danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

GUI Plugins in pd-l2ork?
by Rafael Vega 05 Jan '15

05 Jan '15

Hi, I'm giving pd-l2ork a try for the first time and I would like to use the Zenity Gtk open/save GUI plugin. I have put the .tcl file in ~/pd-l2ork-externals (that directory is in pd-l2ork's path) but the open and save dialogs stay unchanged. Any ideas? Does pd-l2ork support GUI plugins? Thanks. -- Rafael Vega email.rafa(a)gmail.com

future PD-extended development
by Dan Wilcox 04 Jan '15

04 Jan '15

* starting a new thread * * responding to : * > Actually, you're simply trading one shortcoming for another, and I would argue you're shortcoming is a lot harder to troubleshoot. If you provide a monolithic distribution to all of your users, then reproducing their problems becomes exponentially easier as opposed to encouraging each user to install select externals which may clash with each other in unusual ways that may not be apparent otherwise and then trying to backtrace and troubleshoot their specific set up as opposed to relying on one monolithic release that you can easily reproduce on your own computer. If we had infinite time on this rock this may be a feasible option. As for me, particularly considering I am doing this not because I am getting paid to do it, monolithic approach is the way to go with the ultimate goal of having all externals in the extra folder and without any subfolders (in part because duplicates and buggy externals will have been weeded out). Technically it doesn’t matter if you want to build everything together or install things individually. Let’s say we move the externals into separate repos. People working with the vanilla or Pd-L2ork sources or whatever can use git submodules or clone the sources that they need into the extras folder. Then everything can be built together and distributed. If a PD developer wants to change the folder structure and layout of the externals they use and maybe conditionally drop a c file, they can easily do that with scripting that fetches the latest version and then removes the unneeded files. I do this in a lot of projects including libpd where we don’t need to compile all of the vanilla sources. Conversely, some people can still download the vanilla binary and build an external separately or install a precompiled external. Bug-wise, things might show up now and then (as they always do), but if we’re all pulling from the a same place, bug reports can be sent upstream and fixed. Again, it’s easy for this model to work on Github. Judging from the sourceforge bugtracker, the pd community is good about opening bug reports. Also, a simple option to continue extended would be a new “Pd-extended” that is basically Miller’s current Pd vanilla binary with precompiled externals in the /extra folder. This is what I currently use, a few of the precompiled externals from the last version of Pd-extended with Miller’s latest version. If what most people want are the new features of vanilla with GEM and a few set of other externals, then we can do that now if it’s much easier to build those externals without downloading the massive SVN. I have a script which does this on Linux for my UDOO board setup so I have the 9-10 externals my old song patch set requires. This is similar to aforementioned idea of providding all the commonly used externals in one precompiled download. As was pointed out Hans has already established the libdir format and I was using “standard makefiles” etc earlier to refer to that. Again, I think what’s important is to break out the external development from the SVN into smaller, more maintainable repos in order to more effectively coordinate resources. None of us are getting paid, which is why it’d be nice to find a way to make this whole think work for *all* pd development. -------- Dan Wilcox @danomatika danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

can't create [helmholtz~] on Odroid
by Alexandros Drymonitis 02 Jan '15

02 Jan '15

I've downloaded and copied all the files that come with the [helmholtz~] external by Katja Vetter into an Odroid-U3 but Pd can't create it. I've set the directory in Pd's search path, I've also tried to use [declare], but still no luck. With [declare] I get the following message: /usr/lib/pd/extra/helmholtz~/helmholtz~.pd_linux: /usr/lib/pd/extra/helmholtz~/helmholtz~.pd_linux: cannot open shared object file: No such file or directory Typing 'file helmholtz~.pd_linux' in a terminal, I get this: helmholtz~.pd_linux: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, BuildID[sha1]=bbe467ff0725ff41dcab644f1d5e90eb57d45c68, not stripped while other objects, arraysize for example, give this: arraysize.pd_linux: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, BuildID[sha1]=b2b4f077c5008c1037d0e2bd74bb8d0602e62731, stripped helmholtz~ is compiled for Intel processors, while arraysize is for ARM, if I get this right, so the problem is there. Checking helmholtz~ Makefile I see that it uses the g++ compiler, which I have installed, but when I tried to compile the source code, I got an error and the object wasn't compiled. A funny thing is that I have the very same files in a Udoo and there the object works fine (doesn't the Udoo work with an ARM processor?). Is there an ARM version of helmholtz~ somewhere? I'm on Pd-0.46-0, installed with apt-get on Debian Jessy for Odroid. Thanks and happy new year everyone.
