I have something like this on my webpage. Check it out and see if it is along the lines of what you are intersted in.

msgfile (zexy) behaviour
by João Miguel Pais 18 Nov '02

18 Nov '02

Dear list, I have the output from a msgfile object (zexy's version of textfile), which outputs a list. I needed to insert in the beggining of that list the string "msg". After trying with several possibilities, especially pack, couldn't realize this. Anybody has any suggestion of how to insert a string in the beggining of a list? One other issue: compared to textfile, msgfile sometimes (!) has a different behaviour, like - all output is preceed with the string "list" - all lines from the text formated document come with a single bang (as with the same document in textfile comes one line at a time, as normal) - and strangest of all, this happens only sometimes, specially after using msgfile after the first time in a patch (v 0.35t26 in xp) Thanks as usual, João Miguel Pais

Re: [PD-announce] Pd 0.36 test 6 compiled for Mac OSX

Miller, all, I believe Miller Puckette said this around Thu, 14 Nov 2002: >I might have fixed it so that there's no way to get a patch stuck under >the menu bar! > >Also, included the newest Portaudio , tested with the new TCL, cleaned >up some problems here and there. I've been experimenting with Pd 0.36 test 6, and noticed that the MacOSX '-initialdir' workaround for open and save dialog boxes no longer seems to be necessary. Using the linux and NT code gives much better behavior than the workaround, with the current Mac Tcl/Tk. FYI, I found the workarounds in pd.tk|u_main.tk at lines 165, 247, 1067, and 2643. Many thanks for test-6. I personally don't think I would characterize the Mac port as being all that experimental anymore. cheers, adam -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Adam Lindsay +44(0)1524 594 537 atl(a)comp.lancs.ac.uk http://www.comp.lancs.ac.uk/computing/users/atl/ -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

difftime()
by David Sabine 18 Nov '02

18 Nov '02

Hello all, I asked a question a few days ago whether or not anybody has made an object which provides "DateDiff" functionality. I realize that DateDiff is a Visual Basic function....so I'm back to this list asking whether anybody has made an object which provides "difftime" functionality. "difftime()" is a C++ function which serves a similar purpose. What I'd like to do is compare two dates (via the zexy [date] and [time] objects) and return the number of seconds or milliseconds between those dates. For example, difftime("12/10/1999 10:20:21 AM","12/10/2003 10:32:21 AM") = ? seconds I have limited experience with writing and compiling C++, and no experience writing PD externals. I'd appreciate any help I can get. Many thanks. Dave Sabine

OS X? Tcl? Pd?
by Ryan Gallagher 16 Nov '02

16 Nov '02

Howdy, An annoying issue seems to be presenting itself rather often in my experience. When opening large (I mean the windows are large) patches (and some random small ones), the tool bar is hidden behind the OS X toolbar. Thus I'm unable to close, resize or move the window. At other times a patch extends beyond the frame of my screen. I'm unable to reach the corners or resize the window. This often forces me to quit the app and prevents me from opening certain patches as the minimize/maximize buttons don't... OSX? Tcl? Pd? thanks, ryan ===== -r- __________________________________________________ Do you Yahoo!? Yahoo! Web Hosting - Let the expert host your site http://webhosting.yahoo.com

Re: [PD-dev] Pd on OS X

Looking at your last (private) message: >The audio >doesn't stall per se, it's more like values aren't >getting updated consistantly so say a pitch sweep will >"jump" along with the numerical input. ... it's sounding more and more like the real-time issue that Miller pointed out. A pitch sweep shouldn't be interrupted like that, in my experience, unless you have some other processor-greedy apps running at the same time. However, the performance of Aqua Tcl/Tk doesn't help things, either. Controls like number boxes cause a bunch of screen-redraw interrupts that are themselves greedy. Part of it is apparently AquaTk canvasses still use QuickDraw. Still, the stated specs on your machine should be able to run PD fairly well, as long as you minimize the screen updates on patches where you demand good audio performance. And I agree, jMax 4.0 has a very attractive, seductive screen interface. Pity it crashed the first time I tried to turn on DSP. :-/ I think there's a lot still to be optimized in the MacOSX port, though, both in user experience and in performance. Chris Clepper wrote recently about compiling with different optimization settings. Might be worth a bit of experimentation... adam Ryan Gallagher said this at Tue, 12 Nov 2002 08:42:00 -0800: >Hmm... > >So it's a Tcl/Tk thing, or a getting Tcl/Tk to work >well with Pd thing? > >Honestly at this point I'd rather use Pd (more active >community, developed well and often, seems a bit more >avant guard, etc.) but I'm really only interested in >real-time tweaking...

background pics in pd/quicktime codecs in gem
by Orm Finnendahl 15 Nov '02

15 Nov '02

Hi all, 2 questions: 1. Is there a way to load bitmap images into a patcher as a background image? 2. Using Gem with a Linux System I try to play back an Apple Quicktime Movie. I get the following eror: pix_film:: quicktime4linux support pix_film:: libmpeg3 support Trying to load external codec quicktime_codec_rpza.so Can't load the codec quicktime_codec_rpza.so: cannot open shared object file: No such file or directory Trying to load external codec quicktime_codec_rpza.so Can't load the codec quicktime_codec_rpza.so: cannot open shared object file: No such file or directory GEM: pix_film: unsupported CODEC 'rpza'! quicktime_delete_vcodec_stub called It might be a misconfiguration as I found out that rpza is the standard Apple Quicktime codec and Gem's docs say this format is supported. If I can't get this to work: Does anybody know of any way to convert a quicktime Movie to Mpeg2 on a Linux machine or a Mac? -- Orm

[PD-announce] Pd 0.36 test 6 compiled for Mac OSX
by Ryan Gallagher 15 Nov '02

15 Nov '02

Thanks Miller, Although I couldn't get it to compile (prolly my lack of skill) I was able to test the pre-built binary and sure enough, full duplex audio w/emi 2|6 and midi (though somewhat poor performance) with my midisport 2x2. Next adventure - multiple outs. Btw, the hidden menubar thing is improved (though somehow it still ends up half burried). Thank's again. -ryan ===== -r- __________________________________________________ Do you Yahoo!? Yahoo! Web Hosting - Let the expert host your site http://webhosting.yahoo.com
