expr issues
by Alexandre Torres Porres 25 Jun '17

25 Jun '17

Hi, given a recent bug I reported https://sourceforge.net/p/pure-data/bugs/1293/ and someone's request that we should have a more complete and updated expr-help.pd file, I thought I'd make this more complete revision of the object, so I found another issue, and also have proposed some updates/features. And I'd also like to volunteer to create a complete/full documentation of expr functions to be included in the next pd release. cheers

Hi , I would like to announce the release of a patch that corrects the semi-normalization 3D (SN3D) of the HOA library v2.2. The patch is available on the HOA library website. Our apologies for any inconvenience caused. <goog_743606803> HOA Library Website <http://www.mshparisnord.fr/hoalibrary/en/downloads/puredata/> SN3D patch <https://github.com/CICM/HoaLibrary-PD/releases/download/v2.2-beta/HoaLibrar…> All the best, Pierre

Execute command from Pd
by Roman Haefeli 30 May '17

30 May '17

Hey all I'm looking for the best available solution to execute commands from Pd. Ideally, the object would launch the process independently from Pd in order to avoid any lock-ups. Then, it'd be nice if there would be interfaces to access stdout, stderr and the exit code (probably an outlet for each). Third, it should allow to send signals to the running process. I found [moolib/popen], [motex/system] and [ggee/shell] and none of them fits for what I intend to do. [popen] and [system] don't give any feedback at all and probably are meant to run one-shot commands only. [shell] comes closest, it has an outlet for stdout and one for the exit code. However, on macOS only the the second outlet works (and gives correct exit codes) while the left outlet never outputs anything. On Linux, the left outlet outputs stdout, while the right outlet always gives 0 regardless of actual exit code. Ideally, I need something that works on macOS and Linux the same way. I'd like to be able to control a handful of jacktrip[1] instances from Pd. I need to be able to evaluate their stdout to get feedback about their connection status. Also, I need to be able to kill them individually. I'm also happy to explore ideas that think outside the box as long as the solution can be built into a Deken package. Thanks, Roman [1] https://ccrma.stanford.edu/groups/soundwire/software/jacktrip/

Re: [PD] Execute command from Pd
by Dan Wilcox 30 May '17

Seconded. IMO something like [getdir] should be included with vanilla, perhaps as part of get canvas info functionality. I’m using [getdir] for things like this in PdParty and I have a few abstractions for working with paths (p_*): https://github.com/danomatika/rc-patches/tree/master/rc <https://github.com/danomatika/rc-patches/tree/master/rc> > On May 29, 2017, at 10:30 AM, pd-list-request(a)lists.iem.at wrote: > > From: Antoine Rousseau <antoine(a)metalu.net <mailto:antoine@metalu.net>> > Subject: Re: [PD] Execute command from Pd > Date: May 29, 2017 at 6:40:26 AM MDT > To: Roman Haefeli <reduzent(a)gmail.com <mailto:reduzent@gmail.com>> > Cc: Pd-list <pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>> > > > When I distribute the script together with my > Pd project, I'd rather want it relative to the patch, otherwise the > script won't be found on other users' machines. > > As you need [ggee/shell], then why not using also [ggee/getdir] to know where your patch is located ? > > > Antoine Rousseau > http://www.metalu.net <http://metalu.net/> __ http://www.metaluachahuter.com/ <http://www.metaluachahuter.com/compagnies/al1-ant1/> -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

aAaA: any attributes and arguments in Pd vanilla (v. 0.1) Re: Feature Proposal
by padovani 29 May '17

29 May '17

Found this thread ( https://lists.puredata.info/pipermail/pd-list/2016-08/115936.html) some days ago... and then I have forked the IOhannes abstraction that Matt Barber mentions to deal with any number of arguments and to implement the attribute tag recognition. This approach could be used to detect other kinds of "pseudo" types! I hope it is usefull for other people! http://git.nics.unicamp.br/nicspd/patchTools/AnyArgumentsAndAttributes Cheers, José 2016-08-18 13:08 GMT-03:00 Roman Haefeli <reduzent(a)gmail.com>: > Hey all > > After having worked with Python a bit, I'm very intrigued by the many > useful data containers it provides (tuples, lists, sets, > dictionaries). > > At the same time, I am sometimes troubled by the inflexibility of > arguments in Pd.

Weird behavior with Data Structures
by Esteban Viveros 25 May '17

25 May '17

Hi again! I'm have a weird behavior working with data structures... I draw a keyboard and I tried to use clicks to change the color key. but I have simultaneously responses at boundaries. So I draw the keys without boundaries and I have in black keys vertical boundaries response of black key scalar and white key scalar. I can't find error in the patch.. Can anyone confirm if is that a bug or something wrong with me..? :) Patch attached Cheers -- www.estebanviveros.com

Linking externals on windows with mingw32
by Jamie Bullock 25 May '17

25 May '17

Hi list, I'm trying to compile externals on Windows 10 using mingw32 toolchain. Pd version 0.47.1 I always get link errors related to Pd's global symbols being undefined, e.g. undefined reference to `_imp__s_bang' undefined reference to `_imp__s_list' etc My linker flags are: gcc -shared -Wl,--enable-auto-import -o test.dll -L.../pd/bin -lpd I get a similar issue linking externals built with Flext. Linkage seems to work fine except for these symbols. Any ideas?

patch with Loadbang loses data structure
by Esteban Viveros 24 May '17

Hello, I'm drawing a keyboard with data structures. The problem is when I use loadbang to draw the keyboard, black keys are losed. If I bang the routine manually it works like a charm.. What I'm losing? Patch attached.. Thanks Esteban Viveros -- www.estebanviveros.com
