Memento 0.2
by Frank Barknecht 30 Nov '03

30 Nov '03

Hi all, available at this URL: http://www.pure-data.org/Members/fbar/patches/memento-0.2.tgz/view is that: _ Memento _ ver. 0.2 This is a work-in-progress collection of a unified preset system for Pd patches. It tries to loosely follow the Memento [1] design pattern from the Gang of Four book. I propose that a Memento here is realised as a directory in a data pool inside a [pool] object. Currently the pool is hardcoded to be named "RRADICAL". This could change, but maybe it doesn't need to. Inside the Memento, several numbered subfolders are created to store the actual substates. The Memento is only changed or read through the [originator] abstraction. [originator] has two arguments: 1) the name of a Memento 2) $0 Methods of [originator]: * create Memento-name: creates a new Memento, discards the old. * set anything: sets all variables to the values currently in the pool. For use after loading a file with the [caretaker] * substate X: Select substate X (float). It is not allowed to bypass [originator] to change the values inside the RRADICAL pool, with one exception: The [caretaker] abstraction is responsible for saving and loading pool data from harddisk. [caretaker] takes a filename to save and load as argument. A GUI for it is provided in [careGUI]. Methods of [caretaker]: * file filename: sets filename to save/load. * save poolname: saves the contents of the pool named "poolname". For rradical patches poolname currently has to be "RRADICAL" * load poolname: loads the contents, same as save, but the other way around. Communication between [originator] and anything that wants to save anything is done through the [commun] abstraction. [commun] arguments: 1) the name of a variable ("key") 2) $0 [commun] accepts anything and spits out anything if [originator] tells it too (with [originator]'s "set" message). Both $0 arguments above are mandatory to keep Memento reusable, which is the first goal all in RRADical patches. _ Usage _ Every abstraction, that wants to take part in saving its settings with Memento needs to: 1) include an [originator Memento $0] objects 2) cross-wrap all variables with [commun id $0] objects. Because of a bug, for wrapping symbols a [symbol] objects has to be added after [commun]'s outlet. Example patches are mainpatch.pd and listsymbol.pd A single [caretaker] or [careGUI] in the parent patch then can save and reload settings in the pool to disk. _ ChangeLog _ 0.1 * Initial release 0.2 * Use numbered subfolders as states * More examples, careGUI.pd _ Bugs _ * Plenty. * [glue] strips off type identifiers like "symbol", so you currently have to take care of types yourself. Only lists and floats work out of the box currently. * THe "API" is is bound to change. _ License _ Undecided, probably GPL, but for sure Open Source (tm) Comments highly welcome at pd-list or pd-dev. ciao -- Frank Barknecht _ ______footils.org__

PiDiP 0.12.11
by Yves Degoyon 28 Nov '03

28 Nov '03

hi, from the CHANGES.LOG : 0.12.11 added pdp_charcoal to the effect rack : charcoal effect using edge detection, blur, normalization and negate ( it's an abstraction using basic pdp_objects ) fixed compilation problem with latest ffmpeg ( AVFMT_NOHEADER --> AVFMTCTX_NOHEADER ) commented pdp_aa : it introduces useless dependencies ( aalib ) and is not very good added pdp_ocanvas : canvas with some overlay that ffmpeg thing is boring, if you have a cvs snapshot before a certain date, you should use AVFMT_NOHEADER and afer that date, it should be AVFMTCTX_NOHEADER ( in pdp_live~.c ). the problem is that i don't know that date, i haven't checked the snapshot every day. well, just see for yourself. enjoy! sevy

Hi again, Ok so the last mail was perhaps a little dry, but we would really like it if you listers had anything to add .. We're trying to build up a forum where people can run their apps and contribute to a 24/7 generative audio radio system. So if you've got any generative audio apps languishing in your hard drive please let us know! >>>>>>>>>>>>>>previous mail below Heres an early notice/invite for the rand()% internet radio project I am working on with Joe Glimore (check the info below) . Have a look at the site/Listen to the stream and if there's anything you would like to submit for inclusion then please let me know. We're still setting up so forgive the occasional glitch/error in both the site and the stream. We are planning to launch properly at the ultrasound festival in huddersfield uk (end of November). If you want to know any more about the project or how to contribute then just mail me back. Look forward to hearing from you.. :) I know that plenty of you have done some pretty interesting stuff that we'd love to check out/stream !!!

pdp & pidip packaged for OSX
by Yves Degoyon 18 Nov '03

18 Nov '03

hi, as we still couldn't figure out how to deliver two libraries depending on each other using the OSX linker, i released a package containing pdp-0.12.1 and pidip-0.12.10 for OSX. this package can be found here : http://ydegoyon.free.fr/pdp_pidip_osx.tar.gz the streaming objects ( pdp_ffmpeg~ and pdp_live~ ) have also been removed because i couldn't find a way to link them properly. anyway, all other pidip objects are there ( motion detection, compositing, network objects and port of effectv ). enjoy! sevy ps : here are the install notes : ############################################################# These notes were kindly provided by Pedro "No User, No Cry" Soler and were compiled during the piksel workshop held at BEK, bergen, norway during early November 2003 thanks, Pedro & people at BEK ( pier, gisle, ellen, thomas,... ) . 1. download Fink http://fink.sourceforge.net/ This permits to download & install libraries - we like Fink Commander which is a graphic interface to fink included in the osx download. In Fink Commander / Preferences click on the Fink tab and tick "use unstable packages". this is important because otherwise you will not see several of the libraries you need. 2. using Fink, install the following libraries : gsl-shlibs libpng-shlibs libpng3 libpng3-shlibs libquicktime0-shlibs ImageMagick Imlib2 you can either do it one by one from Fink Commander or try this from the terminal (be sure to have set "use unstable packages" beforehand) sudo apt-get install gsl-shlibs libpng-shlibs libpng3 libpng3-shlibs libquicktime0-shlibs ImageMagick Imlib2 ( this didnt work for me - i found i had to do it one by one. libquicktime has quite a few dependencies that it needs to install and this causes problems giving a "Problem resolving dependencies. Check for circular dependencies" error message. fink gives u a list of the dependencies its going to install and u have to install them one by one & then check back if u can apt-get install libquicktime0-shlibs ) 3. You will need X11 for OSX (http://www.apple.com/macosx/features/x11/) u can download from http://opendarwin.org/ or directly from Apple for 10.3. it runs like an application - PDP uses X11 for its windows. 4. download & install PD (we recommend using Hans-Christoph Steiner's OSX PD installer from http://www.pure-data.org/Members/hans ) 5. install the present package in /usr/local/lib/pd/pdp_pidip_osx 6. modify the Pd.command textfile to read like this /usr/local/bin/pd -rt -path /usr/local/lib/pd/extra:/usr/local/lib/pd/pdp_pidip_osx/abstractions -lib /usr/local/lib/pd/pdp_pidip_osx/pdp_pidip IMPORTANT : v4l will not work (this is currently the object used to grab live video) and neither will the window object pdp_xv (use pdp_glx instead). #############################################################
