redrawing arrays crashes Pd (invalid Tcl command)
by Matthias Blau 16 May '13

16 May '13

Hello list, with the current pd-extended 0.43.4, I experience random crashes when arrays are redrawn. The error message always tells "invalid Tcl command", followed by a list of coordinates. So from my limited understanding of things, it seems that the Tcl instruction to redraw the array gets interrupted at random. I have no idea whether that is a Tcl or pd issue but in any case, it makes pd-extended 0.43 pretty unusable for me. As a side-note, this happens on all OSs I have tested so far (Win7, WinXP, Ubuntu 12.04 64bit). Reverting to pd-extended 0.42-5 resolved all issues, but this is of course not the best option for the future. Any ideas? Thanks, Matthias

got jump-on-click arrays working
by Jonathan Wilkes 16 May '13

16 May '13

Hi list, * I got jump-on-click arrays working. Basically you can click anywhere in the graph and the array element in that vertical column will jump to your mouse position. * Implemented "bargraph style" for "Put" menu arrays. (See attached) This is basically a multi-slider. Questions: * using "bit masks", exactly how many flags can I scrunch into a floatarg? Arrays use one floatarg in a pd file to keep 1) the "saveit" flag (i.e., whether or not data is saved with the patch), and 2) plot style, to which I've added one more. I'd like to add a flag for "jump-on-click", and if possible one for x/y ticks. * can I add a A_DEFFLOAT for plot color for arrays? * for bar graph arrays, should the user be able to specify inner/outer color for the bar, or is inner color with black outline good enough? * for arrays with a small number of elements that aren't "jump on click" the UX is misleading: with points-style arrays you can only click on a small undifferentiated part of the line. Should I change this so that the hot spot is the entire line? Thanks, Jonathan

I think it would be nice if it was a minimal library and small commandline app. This way I could use it for something I've been thinking about for a while: an OSX Preview plugin so you could preview a patch right in the Finder. It would make sense for this to be something bundled with pd, like pdsend.

Hi list, I'm following the thread about "Pd > svg" : http://lists.puredata.info/pipermail/pd-list/2013-05/102452.html It gives me energy to make another tool. Sometimes I need to take screenshots of a lot of patchs to show on a website or with a panorama. So I've made a tool with "scrot" program in GNU/Linux : http://jeromeabel.net/files/code/pd/pd-works/scripts/pd2png.zip I don't know if there are better solutions, simplier, cleaner and cross-platform. + Jerome

Hi, > GridFlow has a Pd patch to take screenshots of other Pd patches using X11 (so: GNU/Linux, BSD, etc, possibly OS X, unlikely to work on Windows) > which works for really tall patches Yes, you're right, I saw this idea in gridflow. I will try it. > Well ... basically to me the way to go is really with SVG as a starting point. Because once you have SVG, you can use one of hundred different tools to convert to PNG, JPG or any image format you can dream of With inkscape you can convert .ps into .svg : inkscape pd.ps --export-plain-svg=pd.svg I don't know if we can command Pd to print patchs in .ps (in a command line). It could strong and cross-platform. Jerome

Re: [PD] Raspberry Pi GPIO from PureData?
by Julian Brooks 15 May '13

15 May '13

My understanding is that [gpio] is based on wiringPi https://projects.drogon.net/raspberry-pi/wiringpi/ My understanding also is that wiringPi is the best of the bunch (in C, most direct access to the various pins, well written, most widely made use of, etc.) There's a couple of nice utilities in wiringPi that could be extra objects for a PiLib, including a nice gpio swiss-army-knife type thing as well as i2c control. If anyone's got the skills and some time (I don't have either currently) it could be a really useful addition for Pi and Pd.

tcpserver buffer size issues
by Jeppi Jeppi 15 May '13

15 May '13

Hi, I am having some issues with M.Peach's [tcpserver] object. I get some spureous, incorrect messages which seem to behave in a weird way according to the buffer size. Apparently some messages are splitted. I saw in http://www.mail-archive.com/pd-dev@iem.at/msg06056.html that it was supposed to be a [timeout( message which would help solving this issue, but it seems it is no longer recognised? Any help welcome! Josep M
