Doppler effect implementation
by Frodo Jedi 01 May '22

01 May '22

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 direct plist reading
by Dan Wilcox 24 Feb '20

24 Feb '20

Howdy all, Pd's start time on macOS has always felt a bit *slow*. Recently, someone on the pd-list noticed starting Pd with -noprefs helps a great deal. I did some digging and the core basically performs a system call to the "defaults" command for *each* key/value in s_file.c, including a stat() check if the preferences file exists. That's a good amount of filesystem IO and probably explains why it takes *3-4 seconds* on my machine. For a proposed update to fix this, I just got some code working which reads the plist into a dictionary object directly using the macOS CoreFoundation framework (all C). Reading keys and values is then much faster and Pd starts up almost instantaneously now. Next step would be to updating preference saving as well. I hope to finalize this and put it up as a PR in a week or two for testing. -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

algo for sequencing merges
by Miller Puckette 02 Jan '20

02 Jan '20

To pd dev My default sort algorithm for merging pull requests is oldest to newest. I'm making a minor exception to this in taking on the Mac plist thing (I hate all things Mac and thus am gratefully taking on Mac-specific PRs with no testing) and then, for a wholly different reason, merging the netsend/ netreceive rewrite (as being something less expert about than the author) and thinking that getting up to date on network is an adaptation issue and not a design enhancement to Pd proper. Let me know if one of your PRs is indeed just adaptation and not design and I'll consider jumping the queue on it like I did these. Otherwise I think I'll crawl through the 73 remaining PRs as best I can in chronological order. Meanwhile I have changes I want to make - still agonizing over these. cheers Miller

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
