Re: [PD] contextual pdpedia menu link
I mentioned them a week or two ago in another thread; documents in OS
X usually have a little icon in the titlebar that represents the file
being edited; you can drag it to get a reference to the file (for
copying or opening in another application; for Pd files that's awesome
for dragging to your text editor for editing), or you can right click
it to get a context menu with the parent folders up to the root (great
as a "reveal in finder" function).
I attached a patch that should theoretically add support for them as
well as properly showing the "modified" state consistently with the
rest of OS X apps (which dims the proxy icon and adds a dot in the
close button). But I haven't been able to get it to work with Pd
Vanilla.
I added this to pdtk_canvas_new in my Pd-extended pdtk with static
arguments and the feature does work, so maybe you can try the patch
(my build environment still isn't working):
wm attributes $name -modified 0 -titlepath
{/Users/LukeIannini/PureData/sft/sft.structhausen.pd}
(replace the path with an actual file on your machine of course)
Cheers
Luke

Re: [PD] Cyclone in vanilla?
frank, you are right that the importer would probably use pd's internal pow~, but from my own experience I can only say max and pd are becoming less and less compatible, I ported a lot of patches and also big patches, I always did this by hand, because there are too many things that can go wrong. with max 5 I am not sure, if it is still possible to export the patches text files at all? but there are mor tricky differences, and I don't think cyclone did take care of them (see below), so why hold up the flag for a feature that is not really used by anyone and does not work reliably anyway. (although I agree with you and think it would still be a good idea to rewrite this part of the importer) other max/puredata differences in max messages save their last values, so you can retrigger them by a bang, in pd not. trigger behaves different with number arguments. in max the number will be consistent, in pd it is a placeholder for float(and gets replaced by another number). in max there is this right to left order of execution for objects that are connected without trigger that does not exist in pd. some other things rather apply when you try to expor pd patches. unpack does not work for symbols in max. pd has no integers. a [+] in pd will work for floats and integers, but when you port it to max, it will default to integers. (the same with a lot of other objects, like line...) select does not output a list on its right outlet in max. all the best, marius.

Re: [PD] Cyclone in vanilla?
I don't really think PD-Max compatibility should factor much into decisions about improving PD, especially when it would force 'untidy' concessions on the part of PD to facilitate awkward max paradigms (like right to left execution order, etc.). If [1]**[2] (where [1] and [2] are inlets) seems the cleanest and most consistent syntax, then it should certainly be used; and bite our thumbs at Max. I believe the PD is better than Max; this is certainly true in one important sense: if you write a PD patch, you can give it to anyone with a reasonably modern computer; they will be able to download PD on their machine/OS and execute with full rights and privileges. The same cannot be said of Max. Onward and Upward!

Hmm, strange PNM/PGM should work with tk's built-in 'image'. I would
first try making a .pnm file and see if you can get that working.
Then once that is working, try including it as base64.

For the last 2 years I have very much kept democratisation of tools and universal access in the front of my mind. The entry barrier to any career should always be hard work and learning and not access to an elite club of expensive tools. The computing/IT economy has blossomed because our generation had access to C compilers and cheap hardware as we grew up. I hope the next generation of sound designers will enjoy the same opportunity of commodity tools. At one time I seriously considered using Max because of the readership potential and it was better known within sound design circles. Perhaps my efforts in this area are starting to pay off because I think that has changed. Several job specifications I've seen lately from games developers venturing into procedural audio have mentoned Pd, not Max. Another thing I've tried to do with the book is keep all examples working within < 800MHz CPU requirements. That said, beyond using Pd as the teaching vehicle I tried to keep an implementation agnostic approach, with the idea that if you understand the algorithm and model you can implement a sound object in Pd, Max, CPS or any in-house proprietry synthesis framework. Being able to translate synthesis models between Csound, Pd, Max or whatever is a skill that comes with time. Automatic translation or import scripts are useful for sure, but I think we should recognise that they have now diverged into different things. Since I still believe Pd is the superior design application (by miles) a far more useful automated path would be to spit out Faust symbolic DSP algebra from Pd patches so you could compile patches into externals, Max objects, VST plugins or stand-alone applications. a. -- Use the source ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

Well, presuming we do keep compatability [pow~ 2] will continue to behave as it does in Cyclone. For the proposed intrinsic [**~ ] operator then [**~ 2] would place the argument in the exponent position according to established Pd convention, so [**~ 2] would be the same as squaring. It would replace /\ [*~] though I expect most of us will continue to use that form.

Re: [PD] Cyclone in vanilla?
Hallo, Miller Puckette hat gesagt: // Miller Puckette wrote: > OMG, is it really true that pow and pow~ are reversed from each other in > Max (and hence cyclone)!? Not in Max, but in Cyclone, which uses the [pow] from Pd, which is reverse from the [pow] in Max. According to the Max 4.6 manual both pow~ and pow in Max have base right, exponent left, and the argument sets the base. [pow] in Pd has base left and exponent right, argument sets the exponent (i.e. the message at the right inlet). In the C-math-library, pow is: pow(x=base, y=exponent). I guess, I'm convinced now that [pow~] in Pd should behave like Pd's [pow] and the hell with Max-compatibility. However for Andy this probably means even more work now ... I think, Cyclone's [pow~] should be renamed to something like [rpow~] then. IIRC Cyclone can be made to do some translations when importing Max-patches like for [Snapshot~], a translation pow~ to rpow~ then maybe could be added. I don't think, a warning message in Pd would be necessary, it may be annoying.

(yo, some people suggested that already) it would be educational and it also wouldn't suggest, that puredata is clean, consistent and complete, but it would show, that some effort is required in order to make it consistent and complete for one-self. i think, that would be just frank. it's a project in progress. i believe, that starting with abstractions based on vanilla would be a good idea, even if they are not optimized or require a lot of objects. once they can be replaced by built-in classes, you still could change the abstractions so that they can be used as wrappers, in case the new classes don't have the same name as your initial abstractions. i think, going that way, you can make sure, that the examples from the book will work also in the future, when everything what we miss right now, will be there. i think, this would be the better way instead of adding some dependencies to the book examples, that will be obsolete in the future (or even worse, get replaced by built-in classes with same names, but different behaviour). probably, your book is going to be the killer reason, why those object classes need to be part of vanilla (yeah, i am dreaming ;-) ). frank already started a set. if still stuff is missing, i'd be glad to help as far as i am able to. roman > and I have not found a way to correct > the accumulating DC error.

All I ask is that we settle on something soon (within weeks) and stick to it. It will take me about two more weeks to make changes to all the practicals that use [pow~] after that.

LOTS of planning would need to go into such a > thing. What I generally do *if* I'm doing dynamic patching is write as much as possible into an abstraction and just create copies of that. nqpoly4~ may help with automating that. A very useful trick for these abstractions is to avoid doing connections at all and just pass $0 as an argument. Then inside the abstraction, use [r $1-inlet] receivers where $1 is the $0 of the parent as passed as argument instead of inlets, and [s $1-outlet] instead of outlets. Outside of the patch use [s $0-inlet] to write to the fake inlet, and [r $0-outlet] to read from the fake sender outlet. Do the same for signals with r~/s~ and throw~/catch~ pairs. Most dynamic connections can be avoided by this approach. If you need to pass data from one dynamically created abstraction to another, use a similar approach with numbered arguments. Again this can be seen in action in the redesign of nqpoly4~.pd that I once did and that's in svn/pd-extended as well, or in polypoly.pd.

Re: [PD] contextual pdpedia menu link
That sounds very useful, I have always missed that, but I don't see
the patch attached. I think the patch tracker would be a good place
for it. I just got Cmd-M working to minimize, but it is a hack. I
think that Cmd-M and Cmd-` (to switch between windows) should work
with a Tk app, but somehow Pd has disabled that. I can't find where
tho.
Now that I think about the pdpedia help menu item more, my
implementation is just a first attempt. I am not sure whether it is
the best way to handle it. Does it do the same thing that you were
thinking?
Also, any interest in taking on the pdpedia context menu item? I
think that will require edits to both u_main.tk and g_editor.c, but
it should be relatively straightforward.

Re: [PD] pd-msg
Well... not yet...but if you post the patch, or the part with th 200 or more wires... i would test the difference. I am surprised where this discussion is going...many useful tips so far. I personally dont like that $0 $1 confusion somehow, but thats just because i dont remeber what i did when i open the patch many months later or so.. Wires are somehow more "haptic" and its a part of pd that i like, sort of the typical pd-character, but as in the 24 24 matrix thing - when you have to do more than 100 connections in one patch, then its kind of silly, this weaving so dynamic object creation or just "automated" connecting seems to be a good way.. To come to a little bit more practical example.. I am facing the problem - again with the mapping library - and this is, where it does not work with abstractions - i would like to have one abstraction with a mapping object inside, but not always the same... i post the example, later - where i am now experimenting with this message-thing basically its like that.. lets say you have an abstraction: transfer.pd inside of that there is the core-math object like exponential_curve or exponential_sigmoid so it would be cool to just send the argument "expoential_curve" to the abstraction so this object is created.. well...not very clear i guess.. but i will post it later ..

OPENCV_CFLAGS = -I/usr/local/include/opencv OPENCV_LIBS = -L/usr/local/lib -lcxcore -lcv -lhighgui -lcvaux -lml As we are using the same openCv port I suppose you will not need to modify them but ensure are correct values for you. then do: make clean make and now the objects will compile with no problem in macosx. However, when I try to load any of them PD gives me this error:: /Users/lluisgomezbigorda/pix_opencv/pix_opencv_edge.pd_darwin: dlopen(/Users/lluisgomezbigorda/pix_opencv/pix_opencv_edge.pd_darwin, 10): Symbol not found: __ZN7GemBase10isRunnableEv Referenced from: /Users/lluisgomezbigorda/pix_opencv/pix_opencv_edge.pd_darwin Expected in: dynamic lookup Seems a problem with the linkage of the library but I'm really a neewbe in OSX compilations and don't know how to solve it, maybe someone more experienced in it can put some light here? thanks in advance, ll. marius schebella <[EMAIL PROTECTED]> ha escrito: I hoped for such a long time that someone would start this. thanks 1000 times lluis! unfortunately I could not get it compiling on my os x box.

code directories.
the new version of colorgrid doesn't need anymore
to bundle the image (colorgrid.pnm) file in the package,
but it introduces a new dependency to the tk-img library,
and i don't know of the availability of this library
on every platform,
for now i'm sure it's not listed in pd's dependencies...
not sure it's the way to go.
second, when you build pidip from source,
it defines the path to that image as :
#define COLORGRID_IMG PWD"/patches/images/colorgrid.pnm"
that insure a compiled PIDIP will find the image..
when it's build in extended, i don't know which path should be given here,
as i don't know of a standard path for shared files in pd-extended,
well, basically the simplest thing is to put the right path here in SVN,
and pidip will keep its way of compiling it.

it's done. this is how it works in the previous version (pdp_colorgrid)

no way ;(
I'll try asking in the tk mailing list ...

In order to make the opencv objects work I always had to set colorspace RGB. otherwise, I did no see any effect. I think the default on osx is yuv. anyway, will test a little more. great stuff! marius. ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
