[ pure-data-Bugs-1263139 ] Startup messages too verbose
by SourceForge.net 19 Aug '05

Bugs item #1263139, was opened at 2005-08-18 17:28 Message generated for change (Tracker Item Submitted) made by Item Submitter You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478070&aid=1263139&group_… Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: zexy Group: None Status: Open Resolution: None Priority: 1 Submitted By: Frank Barknecht (fbar) Assigned to: IOhannes m zmÃ¶lnig (zmoelnig) Summary: Startup messages too verbose Initial Comment: Hi Iohannes, this is a wishlist bug: Since Zexy2 single Zexy externals in the path spit out a lot of messages like: [a2l] part of zexy-2.1 Copyright (l) IOhannes m zmÃ¶lnig, 1999-2005 forum::fÃ¼r::umlÃ¤ute IEM compiled: Aug 5 2005 ... when Pd is started. This makes it hard to read anything important that came before zexy is loaded, for example, if Midi devices were found etc. My wish would be to follow the "no news is good news" approach and not print these messages or make them a lot shorter. Thanks, Frank ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478070&aid=1263139&group_…

loadbang order
by Tim Blechmann 17 Aug '05

17 Aug '05

hi all, i'm currently thinking about an elegant way to get rid of the problem of ordering loadbangs. from what i understand, at the moment, there is only the following order of loadbangs: abstractions, subpatches, canvas. but having two sub-patches, i can't be sure, which one is loadbanged first. this can be a problem when having abstractions that should be initialized from other abstractions somewhere in pd (not from a parent canvas). thus i'd propose the following: there are basically two ways how abstractions communicate with each other: inlets and receives. i'd propose that every inlet / outlet / receive declares a loadbang function. before this loadbang function has been run, the outlet events are queued (maybe using clock callbacks), then then the behaviour is the same as currently. for the outlets it's more tricky, since they'd have to register a loadbang on the parent canvas. if someone can think of a more elegant way / has a different opinion, i'd like to hear ... cheers ..... tim -- mailto:TimBlechmann@gmx.de ICQ: 96771783 http://www.mokabar.tk latest mp3: kMW.mp3 http://mattin.org/mp3.html latest cd: Goh Lee Kwang & Tim Blechmann: Drone http://www.geocities.com/gohleekwangtimblechmannduo/ After one look at this planet any visitor from outer space would say "I want to see the manager."

outlet_list
by Ed Kelly 17 Aug '05

17 Aug '05

Greetings, I'm trying to output a list of atoms, and I get a consistency check failed whenever I run my external. the line in the dsp_perform function is: /* to set up the list */ float coeffs[ord]; /* to outlet the list */ outlet_list(x->x_obj.ob_outlet,gensym("list"),ord,parcors); /* and in _new */ outlet_new(&x->x_obj, &s_list); and then I get the following from the compiler: warning: passing arg 4 of `outlet_list' from incompatible pointer type ...so what am I doing wrong?

files imported to CVS - but where are they?

I used cvs to import my files into the repository (Thanks Tim, Thomas) but I co externals and they're not downloaded. I used for example: cvs -d:ext:edkelly@cvs.sourceforge.net:/cvsroot/pure-data import -m "Initial import" externals/ekext/hssc~ edkelly start edkelly(a)cvs.sourceforge.net's password: N externals/ekext/hssc~/help-hssc~.pd N externals/ekext/hssc~/makefile N externals/ekext/hssc~/hssc~.c N externals/ekext/hssc~/m_pd.h I externals/ekext/hssc~/.DS_Store No conflicts created by this import Not sending email for imported sources. ?

pyext looper
by B. Bogart 12 Aug '05

12 Aug '05

Hi thomas +, What was supposed to be very simple task has ended up dissolving my brain and now I have no idea how to solve it so I'm asking on here. What I am trying to accomplish is more or less this: for x in xrange(x_upper-x_lower): for y in xrange(y_upper-y_lower): for z in xrange(z_upper-z_lower): self._outlet(1,x+x_lower) self._outlet(2,y+y_lower) self._outlet(3,z+z_lower) All this does is step through each point in a 3D matrix of points, and output the coordinates of each point. The catch is that I need to send out these messages with a variable delay between them. I tried using the thread example from pyext which works fine on all my machines but was crashing windows badly (I'm using this patch to control a serial control camera, and that camera only works on a particular windows machine at work. So I thought I would rewrite the script without sleep() and use an external metro to drive it. Now I can't figure out how to write a function that I call over and over again that is identical to the above code-block except doing only one iteration at a time. If someone has an abstraction or a solution to this I'd be happy to see it. Unfortunatly the camera is locked away in a room at the University that I can't access over the weekend, so I would need to try and get this to work in the next 2 hours. :( Thanks in advance, B. PS: obviously any until/counter based solution will be great as well, but I had trouble getting that logic to work for me as well.

Hi people, I tried to cvs my externals to the repository today, and I got the message that I don't have write access. Am I getting the command right? or is it something else? cvs -d:pserver:edkelly@cvs.sourceforge.net:/cvsroot/pure-data import -m "Initial import" externals/edext edkelly start I externals/edext/framescore~ I externals/edext/framespect~ I externals/edext/hssc~ I externals/edext/simile~ cvs [server aborted]: "import" requires write access to the repository Best, Ed Dr Edward Kelly Research Assistant in Sonic Arts London College of Communication University of the Arts London ___________________________________________________________ To help you stay safe and secure online, we've developed the all new Yahoo!
