A quick question for C dev - temp file on windows
by Pierre Alexandre Tremblay 24 Jun '22

24 Jun '22

Hello In an external I use the superb tmpnam(x) to generate a temp file path to use and delete. All is good then… for MacOS and Linux that is! In Windows, the code in C does create a file but when I try to pass it to TCL to open there, like in the amazing ELSE’s pic, I can’t - the inverted backslash are deleted. I tried also, like in else, using open_canvas to no avail. Now I tried to use on windows the ELSE’s pic to troubleshoot and it seems I have 2 problems: #1: - PIC will accept the file I create when it is on the Documents folder, but not the exact same file in the temp folder created by tmpnam. So this will work: open C:/Users/pa/Documents/tmp.0.8eDtGO But not this: open C:/Users/pa/appData/Local/tmp.0.8eDtGO === #2 - PIC will only accept with straight slashes / C:\Users\pa\Documents\tmp.0.8eDtGO Won’t work but C:/Users/pa/Documents/tmp.0.8eDtGO’ will === So I wonder if there are pearls of wisdom on temp file generation for cross OS compile. At the moment, if I use the PIC hack of going through canvas_open I get a ‘void’ name, and if I don’t I get errors due to the backslash not being digested by TCL (it seems - the error is as above) p Ps Alexandre, without you and your code, this object would not exist, so 39402940923 thanks!

[PD-announce] Survey and workshop on NIME archiving -- Call for Participation
by Ico Bukvic 21 Jun '22

21 Jun '22

Please pardon the cross-posting. My COMPEL project collaborators and I would appreciate it if you would please distribute this email widely among various communities whose work is rooted in computer music, starting with composers, performers, and instrument and installation designers. Dear all, As part of the preparations for the Workshop on NIME Archiving <https://nime.pubpub.org/pub/oyi0po4b> to be held on 28 June, we look for volunteers to fill out one or more records of *artifact*s (defined broadly) in this survey: *https://forms.gle/A8zNrFVxs9N4aBcp9 <https://forms.gle/A8zNrFVxs9N4aBcp9>* The idea is to check whether categories developed for the COMPEL archive make sense from the community's perspective. We ask that you please consider filling out the survey *before 24 June* so that we have a couple of days to look at results before the workshop. Feel free to make entries also if you cannot make it to the workshop! Given that this effort may benefit the broader computer music community, please note that *both the survey and the workshop are open to any person who is interested in participating*, regardless whether they are registered for the conference. Since this year NIME is an online-only conference, *the zoom link will be forthcoming and will be shared with all survey contributors and conference participants soon*. The workshop will continue discussions in the community on how to best preserve information from the NIME conferences, the NIME community, and the computer music community at large. The workshop will follow up on threads from the NIME publication ecosystem workshop <https://nime2020.bcu.ac.uk/nime-publication-ecosystem-workshop/> (NIME 2020, Birmingham), ICMC 2018 paper <https://dblp.org/rec/conf/icmc/BukvicO18.html>, SEAMUS 2018 conference presentation, and the NIMEhub workshop <https://www.duo.uio.no/handle/10852/50604> (NIME 2016, Brisbane). As we rebuild the COMPEL platform to sidestep technological limitations of the old infrastructure, the main task is to find a solution for an open, future-oriented, engaging, and institutionally recognized archiving solution for the activities of the community that ensures *reproducibility *of archived artifacts. While NIME publications are archived according to the FAIR principles <https://www.go-fair.org/fair-principles/>, currently no solutions exist for archiving information about instruments/interfaces and other hardware/software-based artifacts produced in the community. Neither do we have a system for describing and preserving compositions/pieces, installations, performances, and workshops. We believe that this challenge affects the computer music community at large. The goal of this workshop and forum discussions <https://forum.nime.org/t/survey-and-workshop-on-nime-archiving/306> is to propel the project forward and expand the community engagement. Thank you for your consideration and participation. Should you have any questions, please do not hesitate to contact one of the workshop organizers <https://nime.pubpub.org/pub/oyi0po4b>. Best, Ico -- Ivica Ico Bukvic, D.M.A. Director, Creativity + Innovation Director, Human-Centered Design iPhD Institute for Creativity, Arts, and Technology Virginia Tech Creative Technologies in Music School of Performing Arts – 0141 Blacksburg, VA 24061 (540) 231-6139 ico(a)vt.edu ci.icat.vt.edu l2ork.icat.vt.edu ico.bukvic.net _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

[PD-announce] WebPd (Pd but in the web browser) version 1.0 is coming ...
by s p 15 Jun '22

15 Jun '22

TL;DR : Faster, better, stronger, WebPd 1.0 is coming (featuring WebAssembly, Audio Worklet and more) ... but it needs your support ! WebPd is a highly modular web audio programming toolkit inspired by Pure Data. → it allows Pure Data patches to run in web pages, therefore enabling non-programmers (artists musicians, etc ... ) to design live and interactive audio for the web. → it provides experienced web programmers with a complete audio toolkit that is production-ready, and enables efficient audio synthesis and processing in the browser. 🌱 You can try a demo of the upcoming version here : https://sebpiq.github.io/WebPd_demos/the-graph/www/. 🌱 You can donate money to help making it real : https://opencollective.com/webpd#category-CONTRIBUTE. 🌱 Your money will help moving forward the following roadmap : https://github.com/sebpiq/WebPd/blob/master/README.md#roadmap. ---------------------- FULL VERSION For the past weeks, development of WebPd (1) has picked up a good pace, and the project has reached a state where I feel now confident for sharing a demo (2), a public update on what's going on and a call for crowdfunding (3). 🔊 1. How WebPd Got Here The project was started in 2010 by Chris Mc Cormick when Firefox released the first implementation of an API that enabled live audio synthesis in the web browser. In 2012, I took over and ported WebPd to a different API called Web Audio API (4), which has since become the web standard for live audio. The Web Audio API implementation of WebPd is still the current version (v0.4) and hasn't seen any significant update for many years. It works, but it is hackish and limited. This is due to the fact that the Web Audio API impose its own synthesis and processing functions (oscillators, filters, etc, ... ), and is therefore nearly impossible to customize. Luckily, the situation is now very different than it was 10 years ago. New APIs and standards have been proposed and adopted by all major browser vendors, making it finally possible to build serious custom audio apps for the web browser : - The AudioWorklet (5) : a recent fix to the Web Audio API allowing it to run custom audio code with good performance. - WebAssembly (6) : a binary instruction format which allows to compile code so that it can run in the browser with performance close to that of native applications. With these in mind, I've been meaning to re build WebPd from scratch for several years already but it's a daunting task : it requires an entire re-design of the audio engine, and a full re-write of the code to make the project future proof. Another problem is that there isn't yet a good ecosystem of libraries for writing code with the new web audio technologies mentioned above. Therefore, some generic web audio packages need to be built as part of the project (adding to the complexity and the amount of work). 🔊 2. What's planned for this new version, WebPd 1.0 First, let me say that WebPd does not intend to be a fully-fledged application like Pure Data is on the desktop, but rather a library for developing web applications. In that sense, conceptually, it is closer to libpd (7) than to Pure Data. Of course, you could build a fully-featured user interface, a Pure Data on the web, using WebPd, but that is out of the scope of the project. WebPd's goals are : → to allow artists to take their Pure Data patches and run these in web pages, therefore enabling non-programmers (sound designers, musicians, etc ... ) to design live and interactive audio for the web. → to provide experienced web programmers with a complete audio toolkit that is production-ready, and enables efficient audio synthesis and processing in the browser. For this to be possible, WebPd needs a small community of users and developers. In fact, I have received many messages inquiring about the status of the project and many have offered help with development, so I know that this community exists. The first milestone is therefore to build a minimum viable product, write good docs, resources for beginners to find help, find a good platform for questions and discussion, etc ... making it more easy for others to contribute. In the long run, I would like the development work to be as collaborative as possible, and progressively hand over ownership of the project to the community. 🔊 3. Crowdfunding campaign In order to help reach this first milestone, I am starting a small crowdfunding campaign so I can spend more time on the project in the coming months. You can find here (https://github.com/sebpiq/WebPd/blob/master/README.md#roadmap) a list of what I plan to achieve for WebPd 1.0 with help from that money. If this is something you'd like to help with, you can donate on the opencollective page of the project (https://opencollective.com/webpd#category-CONTRIBUTE). Any amount is welcome. You can also ask questions, or come share ideas here (https://github.com/sebpiq/WebPd/issues/113) or here (https://opencollective.com/webpd/conversations/announcing-webpd-complete-re…).

Some confusion about linux amd64-64 and linux amd64-32 in deken, and what are all the possible variations?
by José de Abreu 10 Jun '22

10 Jun '22

Hello list! I have some questions regarding the architectures available in deken I noticed that deken has many different architectures possible for the packages, as i checked by now (not an exhaustive search) there is at least 8 for linux, (amd64-32, amd64-64, i386-32, arm64-32, armv6-32, armv7-32, armv7-64, armv7l-32), at least 4 for mac (amd64-32, x86_64-32, i386-32, PowerPC-32) and at least 2 for windows (amd64-32, i386-32). There are more? And are they correct? Should i expect that all mac and windows may have the -64 variant too? I ask this because I want to create a table showing all the externals available and which downloads are possible from deken, together with descriptions for each external, so i want to know what are the possible architectures that I am missing... see the (unfinished) table here https://pdwiki.miraheze.org/wiki/List_of_Externals#List_of_Externals So for the first question of the e-mail, what is the difference between amd64-64 and amd64-32? I guess that the first name would be for the architecture of the system, and then the last 32 or 64 would be for single or double precision... but if I search for bandlimited in deken for example, i get that its package is amd64-64 for linux, and i can install it on normal pd, but pd double refuses it, as it is a 32bit-float object. Well, bandlimited was uploaded in 2016, way before the pd double came to vanilla (maybe 2019?), so it makes sense that it is 32bit-float... But there were other reasons for it (and other externals, some from extended) to be packaged as linux amd64-64 instead of amd64-32?

Call-for-Help: tips of the day
by IOhannes m zmoelnig 08 Jun '22

08 Jun '22

TL;DR if you know any quick tips for using Pd, submit them at https://github.com/pd-externals/tipoftheday-plugin/issues/new/choose long version: as you all know, Pd comes with a built-in documentation, that illustrates how to use various objects and stuff (and alex has done a fantastic job in revising these patches in the last months). for a deeper understanding of Pd, there's the HTML manual (which looks nice, after lucarda added some CSS). however, i think that there are a couple of things that need documentation which cannot really be covered by either help patches nor manuals. e.g. "intelligent patching" (where i've spent a bit of time to get it working) or other workflow tricks do not fit well in either category: if they are explained in some help-patches then only people who actively walk through those patches will ever see them (and i believe most people just open the help-patch of a given object they are interested; but what would you open for a non-object that you don't even know about). similarly, i have a feeling that the manual is not the best place for this either (first, the manual deals with the "larger picture" rather than interface tricks; second, the manual is more of an off-line resource (that you may read when not sitting in front of a running instance of Pd). just recently i mentioned the "triggerize" functionality to someone, and they never ever heard of it! to fix this, i've created a small GUI-plugin to display a "tip of the day" whenever Pd is started. i think this (Pd's startup phase) is the right time to learn something new (in tiny bits) - after all, other applications (like my trusted MS VisualStudio 6) did the same). the tips are super-simple: just a short text, with an optional URL for more information and support for displaying (animated) GIFs (patching is oft explained better by showing). the GUI-plugin is available on https://github.com/pd-externals/tipoftheday-plugin/ but there's no release (and thus no deken package) yet. There's also an experimental webinterface where you can browse the existing tips at <https://pd.iem.sh/tipoftheday-plugin/> so far so good. The only drawback right now is, that there are only a very few tips available yet (a total of *4*, mainly for testing). so before this is going to be released to the public, I'd like to collect a few (hundred) more tips this is where you come into play: if you know any quick tips, patching tricks or hacks, please submit them in the issue-tracker at <https://github.com/pd-externals/tipoftheday-plugin/issues/new/choose> (the "Tip of the Day" issue-type will give you a form that you should fill in; this should keep the entry barrier to creating new tips low). thanks for helping out. gmasdr IOhannes
