Regressions regarding data structures
by Roman Haefeli 21 Jan '25

21 Jan '25

Hey Miller et al. Some of my data structures based patches exhibit issues, probably since 1b928e6. I haven't yet the opportunity to deeply investigate and I'll try to open issues proper soon. Since these days it sometimes takes a few days for me to sit down and look at things, I thought it might be better to communicate early that some things might still need fixing. Some patches don't report mouse clicks while they do so in 0.55-2. Another issue is that colors of [drawnumber] elements are black and not in the color defined. Both those findings don't apply to all my patches, thus making debugging a bit more complex. I have often two or more layers of elements above each other so that the lowest layer is optimized for mouse interaction and the top layer for appearance. Maybe ordering of layers plays a role here? I will report with more details when I can provide them. Thanks, Roman

minimum required TclTk version
by IOhannes m zmoelnig 21 Jan '25

hi, TL;DR could we bump the minimum TclTk version to 8.6 (for consistencies sake)? i wonder whether we could agree on a minimum Tcl/Tk version that Pd-GUI code has to be compatible with. The actual value does not matter so much, but whenever I write TclTk code, i would like to know which feature set I can actually use (and whether I actually do need to provide compat code for features that have been in a TclTk-version released 18 years ago) so i did a quick check to see which TclTk versions are actually shipped in the binary packages on miller's site. for the Pd-0.55-2 release the TclTk versions are: - Windows/i386: 8.5.19 - Windows/amd64: 8.6.10 - macOS/amd64+arm64: 8.6.13 - (no linux binaries; i think virtually all linux distributions ship TclTk-8.6 these days, with TclTk-9.0 arriving) those are just the mainstream architectures. there are also: - OSX/ppc: 8.4.7 - OSX/i386: 8.5.19 However, the last OSX/ppc package on miller's page is Pd-0.51-0, and the last OSX/i386 package is Pd-0.53-1. (a more detailed report on which TclTk version is used for which Pd download, can be found at <https://zmoelnig.iem.sh/post/tclpd/> Is it correct to assume, that there is no longer any demand for OSX/ppc and OSX/i386 binaries, and therefore nobody will go into the trouble and build a newer version of Pd for these platforms? If so, we can simply assume that any modern Pd will at least have TclTk-8.5 available. Since then there's only a single platform left that actually uses TclTk-8.5 (that is: Windows/i386), I would like to suggest to bump it to TclTk-8.6 and thus use the same version for all systems¹. (I know that TclTk-9.0 cannot be build for any OSX-system that supports i386; i'm pretty sure that we cannot build Tcl-8.6 on PPC and probably not on i386 either) I guess I could do a PR to update the msw/pdprototype.tgz. but during my survey I noticed that the Windows packages available on miller's website actually do not use the pdprototype.tgz at all but instead ship with a TclTk that was built locally on miller's linux box... mgfasdr IOhannes ¹ of course there is now TclTk-9.x! but we probably should wait first until the major bugs got fixed, both on the TclTk side and on the Pd-GUI side :-)

Exploration: Control a Puredata patch via web GUI
by Winfried Ritsch 12 Jan '25

12 Jan '25

Trying to find "best practices" to control a Pd application via HTML5 or javascript or the like. There is probably solution with Pd as server and (simple to handle) middleware as web-server in between and Pd and browser. As Example usage to clarify the need: Providing a Web user interface (GUI) for a synthesizer with a lot of parameter running on a headless embedded Linux computer only connected with MIDI keyboard over an Ethernet interface for network connection. The logic of UI should be done within the Webpage volume, program change, ... and also key-press should be monitored. Description of any use case and suggestion is appreciated. The goal is to compile different recipes, solutions for comparison and helping to make development decisions. Examples and solution with open Source and free software are appreciated. mfg winfried -- - ao.Univ.Prof. DI Winfried Ritsch - ritsch(a)iem.at - http://iem.at/ritsch - Institut fuer Elektronische Musik und Akustik - University of Music and Dramatic Art Graz - Tel. ++43-316-389-3510 (3170) Fax ++43-316-389-3171 - mobile: 0043 664 2439369
