pixelTANGO, and when a patch needs to know where to look for things...
by B. Bogart 28 Nov '05

28 Nov '05

Hey all, As some of you know pixelTANGO dynamically generates an array of abstractions from a directory. These are a kind of plugin implimented in a patch (pixelTANGO). The biggest issue is installing pixelTANGO on multiple operating systems. Since we need to read the "plugin" directory then we need to know where it is, which could be: /applications/blah/contents/extra/fx /usr/lib/pd/extra/fx or some horrible path in windows. Any brilliant ideas on setting these messages in an abstraction from a hans's package build-system? The only things I can think of are: 1. Try and use zexy to test the OS and assume we know where the fx/ should be installed. The user would only be able to install it where we assume... 2. instruct the user to edit the path manually. :( I really dislike both these options.. Any brilliant ideas about setting this path based on where those fx/ are actually installed? (and in case your wondering according to Miller there is indeed no way of telling where an abstraction is loaded from. (fx/ would be in the same directory as pt.layerfx.) Thanks .b.

incorporating flext into Pd-extended builds
by Hans-Christoph Steiner 28 Nov '05

28 Nov '05

I have been thinking that the easiest way to incorporate flext into the Pd-extended build system is to create pre-made config-*-pd-gcc.txt files and then have the Makefile copy them into place. Would that work ok on the flext side of things? Does anyone have some working ones to contribute? .hc ________________________________________________________________________ ____ http://at.or.at/hans/

importing PDP 0.12.4 into pure-data CVS
by Hans-Christoph Steiner 28 Nov '05

28 Nov '05

I would like to import the latest stable version of PDP in the pure-data CVS so that the build system can build it directly. 0.12.4 seems to be the latest version. Any objections? Volunteers? .hc ________________________________________________________________________ ____ ¡El pueblo unido jamás será vencido!

Passion, fun, elegance, SICP
by Mathieu Bouchard 28 Nov '05

28 Nov '05

I haven't read SICP, but I thought that this email would be inspirational to us. ---------- Forwarded message ---------- Date: 22 Nov 2005 16:34:10 +0100 From: Shae Matijs Erisson <shae(a)ScannedInAvian.com> To: pragprog(a)yahoogroups.com [...] >From http://mitpress.mit.edu/sicp/full-text/book/book-Z-H-3.html This book is dedicated, in respect and admiration, to the spirit that lives in the computer. ``I think that it's extraordinarily important that we in computer science keep fun in computing. When it started out, it was an awful lot of fun. Of course, the paying customers got shafted every now and then, and after a while we began to take their complaints seriously. We began to feel as if we really were responsible for the successful, error-free perfect use of these machines. I don't think we are. I think we're responsible for stretching them, setting them off in new directions, and keeping fun in the house. I hope the field of computer science never loses its sense of fun. Above all, I hope we don't become missionaries. Don't feel as if you're Bible salesmen. The world has too many of those already. What you know about computing other people will learn. Don't feel as if the key to successful computing is only in your hands. What's in your hands, I think and hope, is intelligence: the ability to see the machine as more than when you were first led up to it, that you can make it more.'' Alan J. Perlis (April 1, 1922-February 7, 1990) In my opinion, all programmers should read SICP, I'm glad it's free.

Invitation for the Pd project to join the Linuxaudio.org consortium
by Ivica Ico Bukvic 27 Nov '05

27 Nov '05

Dear Pd developers and contributors, My name is Ivica Ico Bukvic and I have been lurking on the Pd lists for quite some time now (I've also been lucky to have had an opportunity to meet some of you in person at one of the recent conferences). I am a Linux audio user and with it obviously a Pd enthusiast. Considering that I am currently acting as the elected director of the Linuxaudio.org consortium, I would like to use this opportunity to invite all developers and contributors to please consider having Pd become a member-project of the consortium. With this membership, one of the developers/contributors (or commonly the original author) would be asked to serve as the project's representative who would stand for its interests and concerns within the context of the consortium. The Linuxaudio.org consortium is designed to promote the use of open-source audio software whose presence is also on the Linux platform (therefore cross-platform projects are also welcome to join). The membership currently is project-based and does not cost anything and in return the member projects do get exposure whenever there is an opportunity to do so (i.e. Conferences, Expos etc.). In addition, each project gains a one-member board representation and with it an ability to cast vote and/or voice their concerns. Active participation in the voting process is optional so the projects and its members have an ability to control the level of their involvement. The consortium has been in existence for a little bit over a year and during this relatively short period of time has gained 28 member projects. Some of them include Ardour, Rosegarden, Csound (John ffitch being the board member), the recently joined FreeBob project which is currently working on a soon-to-be-released Linux Firewire audio driver, ALSA, Agnula, Core Sound, 4Front Technologies, Mandriva (formerly known as Mandrake), JACK, JAMin, and others. Daniel James (UK) formed the consortium at last year's Linux Audio Conference, becoming its first director. This year he has stepped down and I've been voted as the next director of the consortium. Some of the upcoming projects include creation of a foundation and expansion of membership to end-users as well as institutions and vendors. We will try to generate enough cash-flow through the sponsorship and possible membership dues (something that will be an optional thing as the membership will come in various levels in order to acknowledge the fact that many potential members who may be interested in joining may also lack financial resources to be able to sustain a paying membership; so if you do decide to join, you will not be affected by such changes unless you choose to be). With such funds we hope to undertake various PR projects as well as issue annual awards in recognition of: *projects that have exhibited most progress in the past year *artists whose works have been generated using solely open-source software *institutions which have provided most support to the open-source audio community (software, hardware, services, or via various other resources) We are also planning to sponsor CD series featuring music made solely utilizing GNU/Linux software. Finally, we are also considering to possibly support a bounty-based system where we could try to fund most urgently sought additions to the current Linux audio scene (this would likely be a vote-based system). For more info please see: http://www.linuxaudio.org Needless to mention that having Pd project on the roster will greatly accelerate the recognition of this institution and therefore its outreach. Hence, I would like to urge you to please consider joining the consortium. The actual procedure is rather straightforward: the person who is selected to represent the project should simply e-mail me at ico(a)linuxaudio.org expressing your interest to join the consortium on behalf of the Pd project. I will take care of the rest. Once joined, it is advisable to also subscribe to the consortium's mailing list (it is currently a very low-traffic list) in order to keep up-to-date with the latest news and/or changes. All that being said, I've already talked to Miller about this idea and he has expressed a genuine interest, but considering that Pd nowadays is a labor of many developers and contributors, we both agreed it would be better to post this idea of membership on the dev list in order to allow for everyone involved to voice their concerns, thoughts, and/or ideas. Finally, for what it's worth, I've also noticed that recently there has been a lot of talk on the Pd list regarding forming a foundation and/or bounty-based system of some sorts that would help Pd grow, which is something that Linuxaudio.org could easily complement once its foundation is put in place. Should you happen to have any additional questions and/or concerns, please do not hesitate to contact me. Thank you very much! Best wishes, Ivica Ico Bukvic, composer & multimedia sculptor http://meowing.ccm.uc.edu/~ico/

tgrills' alternate loader function
by Hans-Christoph Steiner 24 Nov '05

24 Nov '05

I just saw the alternate loader patch and really like that idea. It would be handy to write externals in any script language too. Since IOhannes and I have also just written alternate loaders of sorts (HEX and libdir), it would be good to incorporate these two patches with yours and get it into the Pd-extended builds to try it out. There isn't enough info for me to include your patch, to start with, a diff -uw (with context) would make for a more flexible patch. Also, I didn't see how to add new loader functions (I've never worked with pointers to functions in C). You can see IO's and my patches in CVS in packages/patches. loaderHEX-0.39-1.patch and libdir-0.38-4.patch. Both apply smoothly to 0.38.4 and pd in CVS. .hc ________________________________________________________________________ ____ "[W]e have invented the technology to eliminate scarcity, but we are deliberately throwing it away to benefit those who profit from scarcity." -John Gilmore

[ pure-data-Patches-1353230 ] class loader hook
by SourceForge.net 23 Nov '05

23 Nov '05

Patches item #1353230, was opened at 2005-11-10 15:40 Message generated for change (Comment added) made by xovo You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478072&aid=1353230&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: puredata Group: wishlist Status: Open Resolution: None Priority: 5 Submitted By: Thomas Grill (xovo) Assigned to: Nobody/Anonymous (nobody) Summary: class loader hook Initial Comment: Hi all, i'd like to propose a loader hook functionality, so that external logic can be used if the loading of a PD external binary object has failed. This opens up two possibilites: 1) it allows to use external objects written in languages other than C (above all scripting languages) which cannot provide an exposed class_setup function to be used in the same way as traditional C-coded externals. 2) it allows to create external object functionality more dynamically, since the exact name need not be known (and fixed into binary) beforehand. The attached patch is for s_loader.c. The sys_loader function would still have to be exposed in m_pd.h gr~~~ ---------------------------------------------------------------------- >Comment By: Thomas Grill (xovo) Date: 2005-11-23 11:20 Message: Logged In: YES user_id=350252 small usage example: (a "cil" external has to be loaded in PD to invoke the cil_setup function) static int loader(char *dirname,char *classname) { // TODO: check the classname, if it's in our scope // return 0 if it isn't // here we could load some binaries, like in sys_load_lib_internal // or we could just create new pd classes, like in typical xxx_setup functions // ok, class has been loaded return 1; } void cil_setup() { // install our class loader ::sys_loader(loader); } ---------------------------------------------------------------------- Comment By: Thomas Grill (xovo) Date: 2005-11-23 11:12 Message: Logged In: YES user_id=350252 here's a "diff -uw" patch from the pd root directory involving both m_pd.h and s_loader.c ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478072&aid=1353230&group_…
