once again, forgot to send to list... ---------- Forwarded message ---------- From: Mike McGonagle <mjmogo(a)gmail.com> Date: Nov 12, 2007 1:11 PM Subject: Re: [PD-dev] PD Strings To: Martin Peach <martin.peach(a)sympatico.ca> Thanks, Martin, I will have to look at the other thread that is discussing this. I should have look at that a little closer. I was curious about this as a way of handling doing some SQL processing, but then again, if this is not going to be part of the main, then I wonder if it is a bit too soon to actually expect this to be there in subsequent releases.

PD Strings
by Mike McGonagle 12 Nov '07

12 Nov '07

Hello all, I was looking over the latest version of "m_pd.h", and noticed that there is now an "A_STRING" type. Does this mean that PD now supports real strings? Is there any examples of this? Or is this still just in the development stage? Thanks, Mike -- Help the Environment, Plant a Bush back in Texas!

Fwd: Connecting up an SQL Database to PD
by Mike McGonagle 12 Nov '07

I have been gone for a couple of days (under a germ...) and during that time, A LOT has been posted here, and I would like to spend some time reading the responses... But, in that down time, I was playing with SQLite, and actually have an object that can send arbitrary queries, taking input from PD inlets (both float and symbol). After thinking over how to do this, I realized that VERY SIMPLE SQL statments can be entered into a PD objects creation arguments. While not the most elegant, it is very functional for reading. I know the writing works, but just how fast it is will have to be determined. (SQLite writes a lot faster when using transactions, one test I did without transactions, it took almost 2 hours to load 36000 records (each with 10 data elements), with transactions turned on it was a matter of minutes. (These tests were not done using the PD interface, but using the commandline version of SQLite.) Anyway, on skimming the thread, Ben's idea of working with PD struct definitions is a really good one. I want to be able to take a definition for a PD struct, and generate an SQL table based on that. I was playing with this doing some 'SELECT' statements from my object, and with a metronome triggering it once every 20ms, it was reading fairly consistently. So, that being said, I don't have anyway of sending the data to an outlet, it just currently dumps all the result sets to the console. As the amount of data that can be retrieved can be STAGGERING, there needs to be some reasonable thought given to how to handle the result sets. I would think that the access is pretty fast that smaller chunks of data can be read, processed, and then re-read... I don't know if anyone would be interested in seeing the external that I have so far (while there are only a couple of files, it is kind of messy), but the file for SQLite is almost 2.5 megs, just by itself. Compressed, this whole thing is about 1.2 megs. The compiled external comes out to be able .5 megs. I am working on PPC 10.4.10 Mac, so anyone using that could probably use my compiled external. Anyone on other platforms will have to fend with my simple makefile. You can get the files from ftp.wpco.com, with the user 'fsr', and the password of 'puredata'. There is a zip file with the external source, a makefile, a couple of preliminary examples. Try the 'test2' one, as it may be the most understandable. Also, as I said, this doesn't really do much more than spew to the console, but it is a start. Let me have it!!! Mike PS. I am still going to read this whole thread, but that will be a little later.

getting canvas pointer from filename
by Hans-Christoph Steiner 11 Nov '07

11 Nov '07

Hey, I want to make a general purpose way of getting the window and canvas pointers within Pd. I was thinking that making [canvas_name] accept the filename as a symbol, and then it would output the .x%lx.c. So my question is, how do I get the canvas pointer from the filename? .hc ------------------------------------------------------------------------ ---- If you are not part of the solution, you are part of the problem.

I want to have a way where it's easy for users to find the canvas names to send Tcl/Tk messages to them to control their visual properties. It seems to me that using the patchname is the most obvious since all Pd users know about that. If there are multiples, then the object could return a list of canvas names. Then it would probably be useful to be able to query the parent of a given canvas name. [tot] can do a lot of this (not all?), but it's syntax is very much for the Tcl programmer.

Click the [10( on one of the sides. 3) Note that the patch has grown to 504x304 Now the weird bit. 4) with out closing the patch, click the [10( again. 5) Note that it has _not_ grown to 508x308. 6) Close the patch 7) Reopen the patch 8) Click the [bang( 9) Note that it has now grown to 508x308 So it seams it grows 4px per run with a reload. More weirdness. Or observations. 10) Now try the above but clicking the [100( on either side. 11) Note that it still only increases by 4px. 12) Close and reopen the patch. 13) Just save it as you normally would. 14) Note that only one save increases the size 4px. 15) Note that using either the [until] method or the [delay] method doesn't make a difference.
