parsing pd patch files (in php)
by Andre Schmidt 07 Dec '05

07 Dec '05

hi, im now trying two days to find a way how to parse pd patch files, today i found about "recursive functions" and think that would be the solution... but as im not a good coder i cant really modify the "recursive directory listing" code examples that i found through google.... http://www.zend.com/zend/art/recursion.php $delim = strstr(PHP_OS, "WIN") ? "\\" : "/"; function retrieveTree($path) { global $delim; if ($dir=@opendir($path)) { while (($element=readdir($dir))!== false) { if(is_dir($path.$delim.$element) && $element!= "." && $element!= "..") { $array[$element] = retrieveTree($path.$delim.$element); }elseif ($element!= "." && $element!= "..") { $array[] = $element; } } closedir($dir); } return (isset($array) ? $array : false); } but i think i found out how the array should look like: this is the pd patch file: (line numbers are used for better visualisation) 01#N canvas 667 88 332 225 10; 02#X text 21 13 cid0; 03#N canvas 408 254 450 300 cid1 0; 04#N canvas 0 0 450 300 cid1 0; 05#X text 9 6 cid0; 06#X restore 18 30 pd cid1; 07#X text 17 8 cid0; 08#X restore 22 31 pd cid1; 09#N canvas 473 157 450 300 cid2 0; 10#X text 16 16 cid0; 11#X restore 116 31 pd cid2; 12#N canvas 0 0 450 300 cid3 0; 13#X text 14 11 cid0; 14#X restore 203 30 pd cid3; and this would be the array: Array( [canvas0] => Array( [0] => 01#N canvas 667 88 332 225 10; [1] => 02#X text 21 13 cid0; [canvas1] => Array( [0] => 03#N canvas 408 254 450 300 cid1 0; [canvas2] => Array( [0] => 04#N canvas 0 0 450 300 cid1 0; [1] => 05#X text 9 6 cid0; ) [1] => 06#X restore 18 30 pd cid1; [2] => 07#X text 17 8 cid0; ) [2] => 08#X restore 22 31 pd cid1; [canvas3] => Array( [0] => 09#N canvas 473 157 450 300 cid2 0; [1] => 10#X text 16 16 cid0; ) [3] => 11#X restore 116 31 pd cid2; [canvas4] => Array( [0] => 12#N canvas 0 0 450 300 cid3 0; [1] => 13#X text 14 11 cid0; ) [4] => 14#X restore 203 30 pd cid3; ) ) well, im not sure if that array is correct. i did it manually :) and i havent even tested if i can then use that array the way i like, but as im stuck on this parsing problem i desided not to test further until i get this to work.... and maybe my array "design" is not so good anyway... so, i wanted to ask you what would be the best way to parse pd files ? im pretty sure i can do all other things (object drawing, connections) alone, just this parsing thing gives me headache... cheers andre ps. why i do this ? i wanted to display pd patches using "canvas" in firefox 1.5...

reblocking bang~
by Tim Blechmann 07 Dec '05

07 Dec '05

hi all, i just saw, that block~ing a patch with bang~ has an inconvenient behavior ... block~ 128 will result in half as much bangs as the block~ 64, but using smaller block~ sizes than 64 won't result in an improved dsp/message interaction. am i the only one, who sees this as a problem? cheers ... tim -- mailto:TimBlechmann@gmx.de ICQ: 96771783 http://www.mokabar.tk latest mp3: kMW.mp3 http://mattin.org/mp3.html latest cd: Goh Lee Kwang & Tim Blechmann: Drone http://www.geocities.com/gohleekwangtimblechmannduo/ After one look at this planet any visitor from outer space would say "I want to see the manager."

more windows compile issues
by Ed Kelly 07 Dec '05

07 Dec '05

Hi devlist, I've been playing around with a signal external, trying to compile under windows XP with MSVC6 (Oh, how I love unix...) and with various combinations of the #ifdef defines at the top of the .c file I get: Syntax error : missing ';' before 'type' and undeclared identifiers if the final #endif is after the #else statement, Unexpected end of file found if there is no final #endif (as you'd expect), Mismatched #if/#endif pair if the #endif is at the end of the file. All other configurations (leaving out the #ifdef NT block, also changing _MSC_VER to NT) result in the syntax error error. Now, I know I'm being lazy, not finding out what the blocks of code do. Could anyone be bothered to explain this to me? If I understood what these are doing then I might be able to troubleshoot more efficiently than hit-and miss. And...is anyone out there still compiling externs with MSVC??? Hans??? Best, Ed -> -> --> ---> -----> --------> -------------> r3search + praktik EK5perimenz --------------------------------- Yahoo!

Linux-Installer bugfix
by Frank Barknecht 07 Dec '05

07 Dec '05

Hi, attached is a small fix to the externals-build Makefile, which I had to do to let Hans' linux-installer compile several externals. Also attached is another patch which I had to apply to fix the scripts/checkout-developer-layout.sh for me. Actually I'm trying out the new build system to finally use it to do Debian packages using the unified build, which in my view seems like a good idea. However I see some issues with that. For one, running curl to download stuff from the web while building is not acceptable in a Debian package, which has to build without net connection as well. (Actually it would be nice to have the Externals-HOWTO in CVS anyways.) Currently I just disable the curl stuff in the central Makefile. (Btw: Some html-generation is using the <font>-tag, which is deprecated and even illegal in some dialects of HTML.) Then using /usr as a prefix will not install pd in /usr/bin, but still in /usr/local/bin. I haven't found out yet, where to change that. Ciao -- Frank Barknecht _ ______footils.org_ __goto10.org__

[ pure-data-Bugs-1359216 ] print character 123 freezes gui
by SourceForge.net 05 Dec '05

Bugs item #1359216, was opened at 2005-11-17 14:14 Message generated for change (Comment added) made by matju You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478070&aid=1359216&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: None Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: print character 123 freezes gui Initial Comment: On WinXP and Miller's pd039_test7 typing '{' (ascii 123) after print in an object box hangs the gui, apparently because the tcl is waiting for a closing '}' before proceeding. In the source code, dopost() in s_print.c, it looks like four characters are escaped: '\', '{', '}', and ';'. But if they are escaped they should not freeze the gui... static void dopost(const char *s) { ... if (c == '\' || c == '{' || c == '}' || c == ';') <- if it's a dangerous character for tcl upbuf[ptout++] = '\'; <- add a backslash before the dangerous character upbuf[ptout] = s[ptin]; <- then put the character ... sys_vgui("pdtk_post {%s}\n", upbuf); <- then send it to tcl interpreter If I try entering them in a print box I get different results. '\' and '}' are rejected: \}: dropped \: dropped ';' is accepted '{' freezes the gui. In g_editor.c: void canvas_key(t_canvas *x, t_symbol *s, int ac, t_atom *av) { ... if (keynum == '\' || keynum == '{' || keynum == '}') <-a dangerous character { post("%c: dropped", (int)keynum); <-should be dropped, but for '{' this doesn't get printed return; } ...dopost() is called from post() so '{' is causing trouble even when it is escaped with a backslash.

missing libs, welcome.html
by Ed Kelly 04 Dec '05

04 Dec '05

Hey Hans, I checked the fies in /extra from your installer for windoze. The libs I mentioned are not there! Namely: cyclone, ext13, maxlib, iemlib1, iemlib2, iem_t3_lib, iem_mp3, mjLib, motex, pdogg, zexy I notice there are some ext13 items in there - is it no longer a lib? Apologies if you already knew this and are getting around to it! Not all of the options work so well - Welcome.html is rather sparse, so why have it? Again, maybe something you are getting around to (and not so important). PS I know it'll be a while yet, but the 0.39 extended is going to be quite something, don't you think? Esp if python/ruby enabled libs are included with examples. I may make work for myself to suggest this...

making Pd's ./configure find libs in /usr/local
by Hans-Christoph Steiner 04 Dec '05

04 Dec '05

I am trying to make Pd compile on MinGW using ./configure && make. The first problem is that I can't get ./configure to find the Tcl/Tk libs in their default install location, /usr/local. ./configure finds tcl.h in /usr/local/include just fine. Any tips? .hc ________________________________________________________________________ ____ Using ReBirth is like trying to play an 808 with a long stick. -David Zicarelli

Can't compile zexy2 from CVS?
by B. Bogart 03 Dec '05

03 Dec '05

I did did a fresh checkout of the zexy CVS today, and the README looks totally out-of-date (autoconf && ./configure ...) but there is not autoconf input files and no configure script. So I went on a hunch and tried to use scons: bbogart@insitu:~/pd-stuff/externals/zexy$ scons scons: *** No SConstruct file found. File "/usr/lib/scons/SCons/Script/__init__.py", line 870, in _main I see a SConscript file in CVS, but no SConstruct... Whats up? I see lots of posts about this in the archive (for all externals) but nothing about zexy specfically. I guess there is no Sconstruct file in .. relative to externals/zexy... thanks. b.
