Re: [PD] directory hierarchy solution ?

of course, I dont want to invent something new. I am only trying to improve archlinux packages. previously I successfully finished pd-extended and pd-l2ork build scripts accessed via aur.. now my aim is to repair the situation that only one pd distro can installed.. so I am learning from you and from debian... Still I am not sure how to divide that packages into pd-utils (pdsend, pd receive) and other stuff... cheers fk.

Path issue with Pd-extended 0.43.4 on Win7 x64
by Randall Alley 05 Feb '13

05 Feb '13

Hi all, and thanks for the great work on Pd 0.43.4 ! I'm somewhat new to Pd, and am still learning how to get around, but I'm having a problem which I've seen mentioned by others, so I thought I'd report the issue. After installing 0.43.4 using the Windows installer, and launching Pd, I see the following error in the log window (log level 4): Cannot read plugins folder: 'D:/Program Files (x86)/pd/%SystemRoot%/Fonts' Cannot read plugins folder: 'C:/Users/rga/Application Data/' I have confirmed that the Windows 'junction' that redirects /Application Data/ references to c:/Users/rga/AppData/Roaming/ is present and seems to be working normally. I understand that to add a library on load, I should be able to drop it into /AppData/Roaming/Pd, where it should be found and loaded. This is not working. I did create a directory /AppData/Roaming/Pd, but that didn't help. Until this is fixed, can I load a library, in particular Model_Object_Library, in another way, or manually ? By the way, this problem was encountered by a more knowledgeable user regarding 0.43.1 Pd-extended back in April of 2012: http://puredata.hurleur.com/sujet-7111-path-issue-extended-win7-x64 Any help would be appreciated, and thanks !

RE : Plugin auto install feature to Pure data
by colet.patrice 05 Feb '13

05 Feb '13

Hello, that's a quite interesting subject I've been thinking about for pdx since a time, thank you for the contribution... like you said it might be complicated to resolve all dependences required by an external, so I think that adding other dependences like php sql or json would make it even more complicated... Why not just using the native client interpreted langage, TCL-TK? With the help of a command line like wget included with the tcl script and a bunch of pkg files that should be enough, wouldn't it? -------- Message d'origine -------- De : fls(a)rendera.com.br Date : 03/02/2013 20:22 (GMT+00:00) A : pd-list(a)iem.at Objet : [PD] Plugin auto install feature to Pure data Hi list I would like to write before but unfortunately I couldn't. Some weeks ago people started to talk about the development of some auto install mechanism to Pure Data, like the apt-get. It is an amazing idea. I researched and developed some thing like it to my master degree and I would like to contrib with my 3 cents. I studied the plugin structure of Netbeans, Eclipse, Fire Fox, deb and rpm and my contribution is about it. Sorry if I am a little bit prolix. The first thing is to create a plugin package. A a single file to group a lot of files. It can be a zip package, tar, gzip or anything that already has some C open source API to pack / unpack. This way we can upload / download a single file and extract it localy. I will call it the package. Inside the package is necessary to have a package descriptor. It can be a XML file, CSV, txt, JSON or any kind of structured file to describe the content of the package. This file should have the information about the plugin like the author, version, website, license, OS, dependencies, compatibility with PD "flavors" (vanilla, extended, Lork ....), pre-installation script, post-installation script, uninstall script, key words, ... Pre and post installation script are used to create SQL tables, files or other things. Maybe it is not useful in PD. Uninstall script should clean the mess if you want to remove a plugin. Dependencies is a complex problem because it should care about libraries and circular dependencies. Maybe it is the hardest problem to solve. These two things will define the PD plugin: The package file and the plugin descriptor inside the package. The package structure should be defined as a standard. So we should agree, for example, about the name of the descriptor, the folder where the plugin will be and the name of the package file. Probably a package file can be the name of the external.version.something.pd_pkg. In PD we should have a list of installed plugins. It can be a directory with all the plugin descriptors. The user might be able to install new plugins manually. It means a local file in my machine that I choose. PD will open the package, copy the content to the correct folders and copy the descriptor the the correct folder. The uninstall option will do the oposite, delete the plugin descriptor and delete the plugin files. To update from the web, a plugin repository need to be defined. The client should have a list of repositories address. (It is good because different flavors can have their own plugin repositories and the users can choose which one they want to use.) The plugin server can be implemented with a HTTP server. It will publish the list of available plugins on the server. This list can be the list of package descriptors in a tar / zip file. Locally, PD will keep these lists, one for each server, and it will be used to look for new plugins. Add a new server means add the server to the repositories list and download the plugin list of the new server. Since PD has a list of local installed plugins, if you want to check for updates PD compares the servers plugin lists with your local list. Easy task. Different versions should can be shown and the user would be able to choose what to update. These descriptors can be useful also to search for plugins by author, version, key words, versions, ... Update a plugin means to create a list of update, download the packages to a temp directory and install them locally. Just to step foward, the server can have a web interface with some PHP programming, for instance, that automatically update a package, extract the descriptor, put it in the correct folder and put the plugins in the correct folder. Just to be easier to maintenance. Another tool can help developers to pack. Since I did a new plugin I can select the folder, fill a form with the meta-data and the tool will create the package automatically. That's it. Sorry if I wrote too much. cheers f schiavoni _______________________________________________ Pd-list(a)iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

directory hierarchy solution ?
by Fero Kiraly 05 Feb '13

05 Feb '13

Dear friends, imagine: #1 I want to have installed pd-vannilla + gem extenstion to it. #2 next I want to install pd-extended (and gem is included) #3 and finally sometimes i want to use pd-l2ork ( gem is again installed..) so I have 3x gem... it is posibile to do something with folder hierarchy ? my idea on linux: /usr/lib/pd/vanilla /usr/lib/pd/pd-extended /usr/lib/pd/pd-l2ork /usr/lib/pd/externals (all exterals goes here..) . so if I install some external (i.e. Gem) it installs to the /usr/lib/pd/externals folder and every of three 'distribution' of pd can use it ... or i am wrong ? cheers. fk.

Fwd: file format for GEM

Automatized toggle control - patch
by Esteban Viveros 05 Feb '13

05 Feb '13

Hello, Some time I'm trying to finish one patch, but I can't... The patch consist in 4 oscilators (red-cosenoidal , green-square , blue-triangle , pink-saw), in orange I have one Recorder (Gravador) and the output (Saida). All it's razonable working except the toggles on/off control (liga/desl). The idea is: 1) Turning on Saida (liga/desl) then turn on oscilators (liga/desl) and 2) Turning on any oscilator (liga/desl) then turn on Saida (liga/desl) when 3) Turn off Saída (liga/desl) then turn off all oscilator (liga/del) 4) Turn off any oscilator then nothing to do The 1) and 3) are implemented, but when I try to implement 2) something bizarre happend and I have oscilator 4 (pink) on forever with Saida on forever too. I attached the patch for appreciations..
