I'm not sure if i fully understand this, but having inlets/outlets according to a database query relies on the database being static, because inlets/outlets can't be changed afterwards... It sounds like you are better off having just one object type with different messages - but i don't know exactly what you want to do with it. all the best, Thomas

object dependency management
by max jacob 16 Mar '05

16 Mar '05

hallo again. i wonder if there is a way to defer the instantiation of an object if this object depends on the instantiation of another one. my use case: i'm writing an external that allows to use sqlite3 databases in pd. i have an object called "database" that associates a file path to an alias. this alias is used by other objects called "query". by now i'm deferring the binding between the two as far as possible since i have no control on who is instantiated first when a patch is loaded. but i could certainly make many improvements if in the "new method" of the query i was sure that the database object has already been instantiated. (it's a little more complex than that, but anyway...) thanks m.

hi again, i believe there must be a way in pd to register a function to be called after a given time... but i didn't find it. any help? m.

list of lists and list inlets
by max jacob 14 Mar '05

14 Mar '05

hallo to the list, this is my first post. question 1: i saw that the t_atom has a field "word" which is a union including a _glist struct. but there is nothing like an atom_getlist() method. is there a way to embed lists in atoms allowing to build nested lists (lists of lists)? and, if yes, are there some pitfalls due to memory management? question 2: is it possible to have a passive inlet receiving lists? i was looking for something like "listinlet_new", but there isn't. thanks in advance m.

just look at these numbers
by Krzysztof Czaja 14 Mar '05

hi all, these are transfer rates for the connection from pd.38 to pd-gui, measured on an 800MHz PC (the only box I have with windows): windows xp, Miller's pdtcl.dll 430Kb/s linux 2.4, Miller's pd-gui 24Mb/s linux performs over 50 times faster... and I think it scales (2.66MHz linux PC transfers 80Mb/s, no windows there to confirm, though). Perhaps, I should ask windows expert users out there: do not you think this should be improved? What I did was repeatedly sending tcl comments (1Kb long each) via a tot, and storing "clock clicks -milliseconds" readings made after various amounts of transferred data. Then I tried reducing the polling interval in window's pd.tk (originally 20ms) and got 10ms polling 810Kb/s 5ms polling 1.6Mb/s Reducing it further was a bad idea: 1ms interval forced wish84.exe to consume over 90% of cpu by doing nothing else but polling an empty socket. Then I tried to replace polling with setting a "fileevent" callback on a tcl socket channel. Loaded a modified pd.tk directly via wish first, then run "pd.exe -guiport", and got fileevent-callback 3.5Mb/s so, unfortunately, tcl channel adds too much overhead... Have not tried with ws2_32.dll yet. I am tired, this is not my platform. Any clue? Krzysztof

"scripts" section of CVS
by Hans-Christoph Steiner 10 Mar '05

10 Mar '05

I am thinking of starting a "scripts" section of the CVS because I have written two handy scripts for Pd and there doesn't seem to be a logical place to put them in CVS. I have a /etc/init.d/pd SysV-style start/stop script and pd-diff, a rough idea of how to get useful results from diffing .pd files. Any objections, ideas, comments? .hc ________________________________________________________________________ ____ Man has survived hitherto because he was too ignorant to know how to realize his wishes.

[ pure-data-Bugs-1160770 ] crash on saving changed iem-guis in subpatchers

Bugs item #1160770, was opened at 2005-03-10 17:12 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=1160770&group_… Category: puredata Group: None Status: Open Resolution: None Priority: 5 Submitted By: Thomas Grill (xovo) Assigned to: Nobody/Anonymous (nobody) Summary: crash on saving changed iem-guis in subpatchers Initial Comment: A reproducible crash with pd-0.38 stable and devel: try out the attached patch. The patch, contains a subpatcher, containing a iem-numberbox with "init" enabled. When the content is changed and the subpatcher already closed (and the numberbox value not saved yet), saving the patcher will crash pd. This is because in g_graph.c, function glist_grab, x2->gl_editor is used, although it is NULL (subpatcher already closed) ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478070&aid=1160770&group_…

adding new developers...
by IOhannes m zmoelnig 09 Mar '05

alright. since i am now cvs-admin, i'd like to add a new developer to the pure-data.sf project: mr "ritsch" any objections ? and should we discuss such decisions here ? i don't think that there can be much harm in adding new developers to the greater honour of this project.... (esp. if such person is well known to the community) mfg.a.sdr IOhannes
