Re: [PD-dev] [info complete $cmd_from_pd] profiling
by Hans-Christoph Steiner 20 Aug '09

20 Aug '09

I added the [info complete ...] code to the pd-devel/0.41.4 branch. I think that means that I synced all your code changes into this branch, and I've added a bunch of new stuff, including translation support, fixed up the menubar to support dynamic stuff better (like the window menu). There are some minor remaining differences in code organization, which I don't have a strong opinion on. Basically they seem unresolved, so for now I am leaving them as they are in devel. - devel still has pd_post.tcl with pdtk_post in it - devel has ::pd_bindings::sendkey instead of pdsend_key Then I haven't added the audio/midi/startup dialogs or pdwindow yet, just a matter of time. I think those should be dialog_*.tcl like the rest of the dialogs. .hc On Aug 18, 2009, at 1:06 AM, Miller Puckette wrote: > Hi Hans - > > I didn't profile it -- I had to add that because otherwise my usual > patch > doesn't open.

Re: [PD-dev] denormals: svf, freeverb (was Re: [PD] bug in freeverb???)
by Ed Kelly 20 Aug '09

20 Aug '09

Hi Damon, I have tried to implement this technique, to fix the svf~ and I am still getting denormal errors pegging the CPU. Is there anything I have missed do you think? After reading a little bit about unions and uint32_t I think I've used them correctly... If this bug can be zapped for good then I'd like to eliminate denormal errors from the svn for good!

Re: [PD-dev] [PD] pd-toolkit first Release
by Georg Werner 19 Aug '09

19 Aug '09

Hi, thanks for all that positive feedback ... i thought about a new name and i chose [kbd_ctrl]. ( http://www.fricklr.de/uploads/kbd_ctrl.pd ) i still would like to know any idea for improvement or new functionality. @Hans-Christoph: maybe you could include it into pd-extended when iemguts is included? (cause i don't have svn access) cu Georg PS.: Be careful: i discovered that pd will crash sometimes (most of the times if you don't save a patch before closing) if you close a patch with [kbd_ctrl] inside. i think this is a bug in iemguts. dmotd schrieb: > hi georg, > > just checked this out proper and the shortcuts are > brilliant.. what's the scope on building upon > this? i'd love to share in the development if you > think there are more areas that the toolkit could > cover using iemguts. i'm with hans on the > namechange tho, something like [uishrtcts] or > [pdfaster]! > > many thanks to iohannes and luke for their work on > the iemguts objects, great stuff! and georg your > abstraction works a treat (crazy mess!) but its a > great usable example of the lib.. > > i'll be submitting my iemguts test case soon, but > its great to see the potential so well executed! > > cheers, > > dmotd > > Georg Werner wrote: >> Hi, >> >> with the new possibilities provided by iem_guts (thanks to IOhannes m >> zmoelnig and Luke Iannini) its possible now to do patching with the help >> of keyboard shortcuts. in the last couple days i made an abstraction for >> alignment and connection of objects. >> there are so many features that i don't want to explain them here in >> detail.

new pd-devel feature: patches for file associations
by Hans-Christoph Steiner 19 Aug '09

19 Aug '09

So I fixed a couple bugs in Pd-devel and added a new feature which I'd like feedback on: I created a system for associating pd patches to file extensions and created an example wav.pd for opening .WAVs. Basically, create a patch using the text "$FILENAME" for the filename should go, name it after the file extension (i.e. wav.pd), then drop it into 'pd/ associations'. On start-up, Pd will set up the associations for that filetype. When you then open a .wav in Pd, it will open wav.pd, replace $FILENAME with the complete path, then create the patch by sending the contents of wav.pd to pd. The next step would be to use this for drag-n-drop functionality, so when you drop an associated file on a canvas (i.e. voice.wav), it would copy-n-paste the contents of wav.pd to that canvas, with the $FILENAME replacement.

file naming: pd.tcl, pd-gui.tcl, ?
by Hans-Christoph Steiner 18 Aug '09

18 Aug '09

So I just changed the main Tcl file to 'pd-gui.tcl' following the old GUI binary name 'pd-gui'. In merging the code, Miller choose 'pd.tcl'. I don't have a strong preference either way, I'm fine just using 'pd.tcl'. I think others expressed some opinions, so I just wanted to see if anyone wanted to argue either way. .hc ---------------------------------------------------------------------------- All information should be free. - the hacker ethic

msgcat on windows
by Hans-Christoph Steiner 18 Aug '09

18 Aug '09

Hey Miller, I just renamed *_panel to dialog_*, that name works fine for me. Plus I replaced all tabs with 4 spaces, which it looks like you did as well. I just recently created dialog_array.tcl and dialog_canvas.tcl for those dialogs and cleaned things up some with the panels. I just noticed another thing, you disabled msgcat on Windows. I haven't done any Windows testing yet, so I am guessing you had troubles with msgcat on Windows. AFAIK, msgcat should work fine on Windows. Can you shed some light on the issue? .hc ---------------------------------------------------------------------------- Computer science is no more related to the computer than astronomy is related to the telescope. -Edsger Dykstra

[info complete $cmd_from_pd] profiling
by Hans-Christoph Steiner 18 Aug '09

18 Aug '09

Hey Miller, Just going thru the code you checked in. I noticed this in ::pd_connect::pd_readsocket, I am guessing this is the re-add any "\n" that are missing. I am curious, did you profile it at all? I was hesitant to do that because I thought it might have a big performance hit. Here's the snippet in question: while {![info complete $cmd_from_pd] || \ [string index $cmd_from_pd end] != "\n"} { append cmd_from_pd [read $pd_socket] if {[eof $pd_socket]} { close $pd_socket exit } } .hc ---------------------------------------------------------------------------- "[T]he greatest purveyor of violence in the world today [is] my own government." - Martin Luther King, Jr.

getting rid of #/$ and sharptodollar()
by Hans-Christoph Steiner 18 Aug '09

18 Aug '09

I'm hacking away on the array panel and generalized the panel stuff in the pd-gui and I ran into the sharptodollar() and mofo stuff in pdtk_array. It seems there has got to be a better way to do this, like properly escaping the $ on the Tcl side so Pd handles it properly. Can anyone think of a reason not to try this? .hc ---------------------------------------------------------------------------- I have always wished for my computer to be as easy to use as my telephone; my wish has come true because I can no longer figure out how to use my telephone." --Bjarne Stroustrup

tooltips idea
by Hans-Christoph Steiner 18 Aug '09

18 Aug '09

Hey, So there has been a revived discussion of adding "tooltip" support to inlets/outlets, based on Günter's old patch. I think we should open up the discussion again to see if we can come up with a solution that Miller would accept. I believe his original objection was based on the fact that the patch added a record to the t_class struct. So I was thinking that instead of storing the tooltip data in t_class, it could be stored using a custom struct like t_inletdescription that was then added to object's class. Another possibility would be to add it to the t_text/t_object struct which every object has. I guess the advantage of putting it into t_class is that there would only be one copy of it. That makes sense since every instance should need the same data. Having it elsewhere would mean multiple copies of the same data, AFAICT. .hc ---------------------------------------------------------------------------- I hate it when they say, "He gave his life for his country."

autobuild externals, motex and ext13 makefile issues..
by dmotd 17 Aug '09

17 Aug '09

greetings i've taken over the job of packaging pd-extended on archlinux, and in doing so i've found a side effect to the changes initiated at r11880 (re: after a good argument with IOhannes in Brazil, I think we have a good Makefile template here), last edited r11891. this template (which was also applied to motex) is causing the 'install' directive to concatenate the DESTDIR and objectsdir variables, both set in the externals root Makefile, and both containing the majority of the same path. the result is a duplicate file path, causing both of these libs to be installed to the wrong location! this is effecting my builds here, but it is also noticible in the autobuild farm logs - see the lastest for confirmation. hopefully this can be fixed asap, but i was also wondering what ideas have come from these discussions for the externals build process? is this template designed to be applied to the each build target? cheers, dmotd REFERENCES: http://pure-data.svn.sourceforge.net/viewvc/pure-data?view=rev&revision=118… http://autobuild.puredata.info/auto-build/2009-08-15/logs/2009-08-15_01.58.…
