Hi all, I am searching for a Pd implementation of a doppler effect as realistic as possible. Any recommendations? Any patch/external already made and well tested? Cheers FJ

macOS 10.15 notarization
by Dan Wilcox 13 Dec '19

13 Dec '19

Howdy all, The newest version of macOS, 10.15 "Catalina", is out and with it comes a new "Notarization" requirement for applications, etc: https://developer.apple.com/documentation/xcode/notarizing_your_app_before_… <https://developer.apple.com/documentation/xcode/notarizing_your_app_before_…> As far as I can tell, applications do not need to be built via Xcode, but need to be screened and Notarized by Apple. I'm not 100% certain if this applies only to applications signed by a Developer ID or for *all* applications. Regardless of whether we approve of this security step or not (I don't), the practical matter is that Pd *may* suddenly not run for users on 10.15 as it is not notarized or signed. OTOH software that is not signed and is installed "from the wild" *may* still be launched via Right Click -> Open on first run... although I'm not sure. Apple has made the Notarization requirement optional until January 2020 to ease the transition. At this point, it would be helpful to hear from someone who has the new OS if Pd runs and if there are any warning dialogs. In the worst case, we will need an Apple developer account ($100 a year) to signed Pd for distribution and notarization. This also requires using the Xcode 10+ developer tools which rules out Miller's 10.6 build system for this step. it could be integrated as a makefile step. I have a dev account and can do some testing, when needed. In the best case, Right Click -> Open on first run still works. :) -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

pd compiled for web with emscripten
by Claude Heiland-Allen 26 Nov '19

26 Nov '19

Hi! As a proof of concept I modified pure-data and libpd just enough to get it to compile with Emscripten and run some patches: https://mathr.co.uk/empd/ Only -nogui mode. You can make GUIs using SDL2 and OpenGL, or using other web APIs (HTML forms, SVG, etc). Performance (provided you compile in Release mode) is about 2x worse than native in one of my tests. Changes were mainly annoying rather than hard: - Emscripten is stricter about calling function pointers with the correct type, this means pd_typedmess explodes from 6 cases to 60. - I also needed to special-case pd_objectmaker in more places, because its methods have return values other than void. - These type errors are only visible at runtime, so I may have missed some - please report. Some other smaller fixes I may make pull-requests for soon. Claude -- https://mathr.co.uk

Using PD and Patreon
by Agustín Riolfo 28 Oct '19

28 Oct '19

Hello, and thanks for your time. My name is Agustin Riolfo and I am developing a music software to make guitar effects. I found that your software is suitable for my application. I won´t sell the software but I would like to have a Patreon account so that if some fans would like to, can contribute with me. The question is, being that the software would not be sold and that would only be donations, is there any problem on having a Patreon account? Moreover, if I use blocks like [expr] or [expr~] that use a GPL licence (as far as I know), would donations through Patreon be a problem?? Thanks in advance

Deken GPG signing question
by Jamie Bullock 27 Oct '19

27 Oct '19

Regarding Deken’s GPG signing step… it seems that a “package” or “upload” succeeds even if I type an incorrect GPG password. I discovered this because I accidentally typed a wrong password and the upload still went through without errors. Can someone explain GPG works with regard to Deken, and what the consequence is if the wrong password was typed? Thanks Jamie

Deken not adding architecture
by Jamie Bullock 24 Oct '19

24 Oct '19

Hi list, I’m currently trying to package up a set of externals for Deken release. Following the docs here: https://github.com/pure-data/deken/blob/master/developer/README.md <https://github.com/pure-data/deken/blob/master/developer/README.md> Using version 0.6 of Deken on macOS 64-bit. Based on the README, my expectation is that if I type: $ deken package -v 1.0 foo It will create a file: foo[v1.0](Darwin-x86_64-32).dek However it actually creates: foo[v1.0].dek Is this a Deken bug, or do I need to do something extra? Thanks Jamie

networking updates
by Dan Wilcox 11 Oct '19

11 Oct '19

Howdy all, Christoph and I have more or less finished some work that updates Pd's networking and also fixes some bugs and a couple pain points: * IPv6 support * multicast * netsend: optional from hostname & port outlet * netsend: connectionless UDP, no more connection refused (fire & forget without having to manually reconnect) * netreceive: settable timeout which defaults to 10 seconds (no more super-long frozen Pd) * improved error printing with netsend and netrceive Find Last Error support * various small bug fixes (no more polling errors after socket is closed) The pdsend & pdreceive utils are similarly updated. The discussion & pull request on Github: https://github.com/pure-data/pure-data/pull/577 <https://github.com/pure-data/pure-data/pull/577> If you can build Pd and want to try this out, the branch is called feature/netobject-updates The overall approach taken is to keep IPv4 as default and detect IPv6 addresses so this should not affect existing patches. The IP version handling should also degrade gracefully based if IPv6 is not available. An added bonus is hostnames now resolve (ie. google.com <http://google.com/>) and you can also listen on a hostname if your system can grab it (ie. computername.local). One current limitation is that Tcl 8.5 does not have IPv6 support, so the core communication with the GUI remains IPv4. -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

Re: [PD-dev] First complete keyboard navigation prototype
by Dan Wilcox 10 Oct '19

10 Oct '19

*Not really feedback, but just a general response.* One thing I would suggest would be to make this an optional feature in some way. Maybe we can work together with IOhannes and Christof to propose changes to the Pd sources to allow for adding in this kind of functionality without *requiring* it to be built into the core itself. I have been thinking of these kinds of approaches since I see this being a greta feature for the GUI but basically unused for something like libpd. In the latter case, I'd like to simply not compile it and the easiest way would if the main functionality is in a separate set of files that can be left out. This might be a process that has to happen later on, but something to think of for now in order to balance the addition of new features while maintaining the possibility for a fast, slim core. > On Jun 10, 2019, at 10:30 AM, pd-dev-request(a)lists.iem.at wrote: > > Date: Sun, 9 Jun 2019 19:16:36 +0000 > From: Henri Augusto Bisognini <msndohenri(a)hotmail.com <mailto:msndohenri@hotmail.com>> > To: "pd-dev(a)lists.iem.at <mailto:pd-dev@lists.iem.at>" <pd-dev(a)lists.iem.at <mailto:pd-dev@lists.iem.at>> > Subject: Re: [PD-dev] First complete keyboard navigation prototype > Message-ID: > <CP2PR80MB0386C0D2C66D1CE34F458BE3CC120(a)CP2PR80MB0386.lamprd80.prod.outlook.com <mailto:CP2PR80MB0386C0D2C66D1CE34F458BE3CC120@CP2PR80MB0386.lamprd80.prod.outlook.com>> > > Content-Type: text/plain; charset="iso-8859-1" > > Thanks Christof!
