Reason for not allowing '{' and '}' in Pd?
by Zack Lee 14 May '18

14 May '18

Hi, I'm trying to add a Lua scripting feature for my external which will allow users to write and run Lua scripts directly in pd as object arguments similar to how [expr] object works. But the problem is curly brackets are used for table literals (e.g. a = {1, 2, 3}) in Lua, so it is not possible to create tables using this method. I could only use '{' and '}' by editing the patch with a text editor, then reopening the patch in Pd. I found this code inside canvas_key() function from "g_editor.c" file. if (keynum == '\\' || keynum == '{' || keynum == '}') { post("keycode %d: dropped", (int)keynum); return; } I would like to know why these 3 characters are not allowed in Pd. Would there be any problem if we remove the above code from Pd? Thanks! Best regards, Zack

PdLua for ARM
by Alexandros 13 May '18

13 May '18

In deken there's no binary of PdLua for ARM. In the README for the Linux binary I read this: "1. edit Makefile.static to configure your PLATFORM and PDINCLUDE" But there's no Makefile or any .c file (there's a pd.lua file though). What do I need to compile PdLua for ARM? Which Makefile, any sources that might not be included in the available packages?

hi, trying to install an up-to-date IEMGUTS for/on an old mac-ppc. (because deken presents an old version) the readme.txt of IEMGUTS says: installation:: -------------- #2> make #3> make install "make" seems to work allright, but "make install" gives 'no rule for make target install'. what to do/change? rolf

polynomial pairs in lpc filter
by Simon Iten 11 May '18

11 May '18

hi list, this is more of a general DSP question... i am working on an LPC playback and mangling system for axoloti. i have most of it working and i am now trying to shift formants in the filter to change voice character. i found functions to convert reflection coefficients into polynomial pairs and presumably i should be able to shift filter frequencies in this representation of the data. unfortunately i have no clue how to do that. any hints, papers, code snippets etc. are very welcome. or if someone wants to take the time to explain, you are of course more then welcome thanks for any suggestions

[PD-announce] [ARRAST_VJ] - Pure Data/GEM Video Mixer/Mapper - www.arrastvj.org
by Bruno Rohde 11 May '18

11 May '18

Hello friends, I introduce you to [ARRAST_VJ], a tool for live video mixing and mapping (with audio) developed with Pd Vanilla + GEM. [ARRAST_VJ] was developed in the Linux operating system, in which all features work. Mac OS computers running GEM also run the full version. For Windows users, a "Light" version was created, without audio and with other small differences. Finally we have completed the translation of the manual and patch comments into English. The patch was released in Brazil in 2017 with documentation in Portuguese. You can find downloads and complete information about the project on the site, including video tutorials (in Portuguese) and other records. This work was only possible thanks to the efforts of many people in this community, I am very grateful to all, and I hope to continue contributing for many years. Doubts and comments are welcome here or on our channels on facebook, instagram, youtube, gmail (links on the site). I hope it's useful to you! www.arrastvj.org https://github.com/brunorohde/ARRAST_VJ -- Bruno Faria Rohde _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

restart bash script
by michael strohmann 10 May '18

10 May '18

Hi ! thanks to Jack and Roman this bash script successfully restarts pd: #!/bin/bash sudo puredata /path/to/patch.pd & PID1=$! while true do if [ ! -d /proc/$PID1 ] then sudo puredata /path/to/patch.pd & PID1=$! fi sleep 1 done what i don’t yet get is: what happens if pd is still running but hanging in limbo, frozen in the watchdog loop. i mean sometimes pd is still running but does not output sound or react to input… is there a solution to kill and restart pd in such a case? Thanks ! Michael

pow/pow~ and negative input, a fix proposal
by Alexandre Torres Porres 09 May '18

09 May '18

Hi, I'm basically reviving a discussion I found on the list archive from 5 years ago, see: https://lists.puredata.info/pipermail/pd-list/2013-04/102279.html Not much came out of it besides the assumption this could be a concern to prevent inf/nan results! As in: [-1( |[pow 0.5] | I can see that, because we have other examples like that in Pd, like log/log~ outputing -1000 for <= 0 inputs. But still, that's not a good reason to prevent something like: [-1 ( |[pow 2] So I did a Pull Request where I still make it output "0" when pow/pow~ would give 'inf' or 'nan' but still allow us to calculate the power of negative numbers. Here it is: https://github.com/pure-data/pure-data/pull/356 (In another commit, 'm also proposing log to behave like log~ anyway) I come to the list to query if anyone thinks there might be a concern in expanding the behaviour of pow/pow~ I personally cannot think of any use case where someone relies on pow(-1, 2) generating "0", it just seems wrong to me (i.e. a bug) and allowing it to do that wouldn't break things. cheers

problems with [list store]
by Liam Goodacre 09 May '18

09 May '18

In 0.48.1, [list store] is going a bit wonky. It looks to me like "get" is being interpreted as "range" and "range" isn't being interpreted at all. For instance, if I store a list, say "1 2 3 4 5", "get 1" --> Bad arguments for message 'get' to object 'list store' "get 1 3" --> 2 3 4 "range 1" --> list store: no method for 'range' "range 1 3" --> list store: no method for 'range' Note that because of these problems, the [until] loop in [pd example3] of the list-store help file crashes my machine. I'm on Ubuntu 18.04, using the repository version of PD. Liam
