Yo Chris,
Ya, you'll need XCode to get gcc and friends... it is free on the
install disc or you can download it after making a (free) account at
http://connect.apple.com/ ; I think this info applies to all
reasonably recent versions of OS X (10.3+ and perhaps earlier)

This could be the problem, registering classes is usual in .pd_lua files
but not .pd_luax files.

where did you define get_word_from_inlet? You should just be able to
use 's', as that's the symbol atom passed to the inlet method.

This seems to be a Lua problem more than a pdlua problem - you use
get_word_from_inlet() but don't define it anywhere.

Re: [PD] Free rotation in GEM
hello sorry if i misunderstand. rotateXYZ will rotate in X direction, then in Y, finally in Z. if you wish to rotate in Z, then in X, you just need 2 rotate objects: the 1st for the rotation in Z, then an other for the rotation in X. anyway, there is no matrix manipulation that i was not able to do with rotate/rotateXYZ/translateXYZ/scaleXYZ/shearXY.. so i'm quite sure you don't need anything else than this standard objects for simple matrix rotation. so i think you need 1 [rotate] to rotate the vector axis of the object, then a accumrotate. if i misunderstood, could you please describe your problem better. I think you can also use GEMgl objects to multiply the matrix with a custom one, but it's to much complex for what you need. cyrille PSPunch a écrit : > Hi Mathieu, > > > I have not looked into GridFlow much, but I had the impression that its > main concept was to add matrix manipulation features to Pd, all of its > visual capabilities being just one of the many results of data you can > manipulate with matrix.

mmh sure, I just used that cause that was the part of code frank

A pdlua manual is on my todo list, but for now the examples are the best

I manage to get it work with this code:
function LSpell:in_1_symbol(s)
word = s
cmd = "echo " .. word .. " | /sw/bin/ispell -a | grep \\*"
p = assert(io.popen(cmd))
result = p:read("*all")
if(string.len(result) ~= 0) then
self:outlet(1, "symbol", {word})
end
end
It outputs the word only if it exists in ispell.
Can Lua be used as a more stable shell interpretor for all the functions?
It is of a big interest!!

Re: [PD] really annoying question about tildes~
I think we have to face that pd's current features are not able to meet all needs: namespaces, special characters, fast loading, aliases... what is missing? does pd have something like a "registered objects list"? an index, which is created on pd startup that holds the name and aliases to all objects that can be created but without loading the objects themselves? maybe a hybrid somewhere between path information and the loading of a multi-external library. is this the way how it is done currently? this list should be dynamically editable and would hold the aliases for namespaces: counter = iem/counter loading the iem counter as default, but still enabling the creation of cyclone/counter. also all other aliases could be included. and it might as well speed up starting of patches since there is no need to search all directories for every object. it would extend the functionality of "path" by actually reading out a small amount of object information which allows for sorting, aliasing... marius.

Yeah, sorry, that's probably my fault. My little Lua example was meant
to be a kind of pseudo-code, sorry. But I see that you already solved
the issue with Claude's help.
Btw. other than in Python or C, variables are global as default in Lua.
I also didn't include it in my "pseudo-code" but instead of this:
> cmd = "aspell -c " .. word
> p = assert(io.popen(cmd))
> result = p:read("*all")
you should declare variables as "local" like this:
local cmd = "aspell -c " .. word
local p = assert(io.popen(cmd))
local result = p:read("*all")
Sorry for adding confusion like this.

[PD] bringing an open subpatch to the foreground needs one click too many
Hi all, I don't know if it's pd-specific or a Gdm thing... Though it's a simple 'problem' it's kind of long to describe. here goes: 1. Click a subpatch object in a patch. It opens the subpatch in a new window. 2. click on the parent patch's window so the subpatch gets hidden behind it. 3. Click on the same subpatch object again. Now the subpatch window doesn't come to the foreground, but instead the corresponding window list item is highlighted (blinking). 4. Now, clicking on this Window List item (in the bar at the bottom of the screen) doesn't bring the subpatch window to the foreground, but instead it minimizes it, as if it was already in the foreground when you clicked the Window List item. To finally bring the subpatch window to the foreground you have to click the Window List item once again...which is one click too many for my lazy fingers ;) Does anyone else find this annoying or is it just me ? thanks, Tim ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

For example with attached pdlua external (needs pdlua)
You need some kind of external, as it's not possible with pure Pd to
split a symbol at a certain character. You could also use something
like Zexy's symbol2list for this task - use
[92(
|
[makefilename %c]
to generate a backslash symbol to feed into s2l's right inlet then.
Using Lua has the big advantage that you can do some more string
processing in the same object immediatly and in my experience, once
you start with text processing you often need a bit more power anyway,
that's why I'd prefer Lua here.

Pd insists on having the class name in the setup function. If it was just setup () like Max/MSP, then that would not be an issue. So we've discussed this a lot, but what needs to happen is that some code needs to be written and tested. IOhannes has spend a ton of time on this issue, and is understandably frustrated.

[PD] Pd/MAX grudge match in Toronto next Thursday
Hey folks Just in case there are Pd users hanging about in or around Toronto that I'm not in regular contact with who don't have anything to do next Thursday night. This is bound to be loads of fun. All the participants are really cool and funny people. - Anything you can do (in Max), I can do better (in PD) Date: Thursday, July 24, 8pm onwards Cost: Free! Yes, FREE. No need to register- come one, come all! With Celebrity Guest Host Misha Glouberman Competitors: Frank Tsonis vs. Dafydd Hughes and David McCallum Come take sides in this fight to the death between those open-source PD Commies and the right-wing, proprietary, puppy-hating MAX/MSPers. There has been a long and bloody rivalry between those who would make new media art with Pure Data, a free, open source graphical programming language, and proponents of MAX/MSP, Pd's slick, commercial half-brother. We intend to open these old wounds, pour salt, beer and whatever else we can find into them, push both programs and programmers to the brink of collapse and determine once and for all which is better. Join host Misha Glouberman as he leads our contestants through a series of increasingly difficult challenges with play-by-play commentary by Nicholas Stedman and game show music with Graham Collins. Watch as Frank Tsonis (team MAX) and David McCallum and Dafydd Hughes (team Pd) try to come up with the fastest, sexiest and most effective solutions, all the while fighting against each other, the clock, and the inevitable nerds who think they can do it better. If you have experience with either of these programs (or if you don't) and you think you can do better than our resident gurus, or even if you just want to play along, feel free to bring a laptop, work on the challenges, aid or abuse our contestants or just check your email. The popcorn's on us; it's free to watch, participate, heckle, throw fruit, and bet on who's gonna get an ass-beating.

Re: [PD] Free rotation in GEM
Hi, My primary goal is to place an object you can rotate by dragging the mouse. Basically, whenever the mouse is clicked to start drag, I want to rotate the object on the X & Y axises. Up to this point is no problem, but I want the rotation to begin assuming the direction of the viewer being the bases of the axis. Using one [rotate] object, I can get the object to rotate in the behavior I expect only on the first drag. Ideally, each time the mouse button is released, the base (fundus? basal?) of the rotation vector should be updated... I think. By chaining [rotate] objects, I can use one to rotate the rotation axis and another to rotate the object from that point. However, I have not found a method of summing multiple drag actions. Although I may be wrong, I think what I need to do is, 1. Prepare two rotation axises I. Angle of the axis II.Angle of the current drag session 2. When the mouse button is clicked, rotate object to angles I + II 3. When the mouse button is released, sum I + II and wait for a new click. And again, although I may be wrong, my current understanding is that step 3 will require multiplying the X-Y-Z angles converted to quaternion, or some other method which will rotate the Z axis at some point by summing rotations based only on the X&Y axises. Using procedures completely different from the one mentioned abouve, I was able to achieve the expected behavior based on [accumrotate] but I found no simple way of managing the current angle. Unfortunately I have torn down the patch. If it would clarify anything, I will try to put together another one later today.

If you tried GridFlow's bundled examples you'd see what I use GridFlow for. I suppose that I could add some other people's examples in the package, if they sent it to me for that purpose. There is already one patch by Roman Häfeli in GridFlow's examples though. GridFlow does not support quaternions. I bet it's possible to add support for it using abstractions, but it wouldn't be fast. But I'm willing to add it to the core... there's already a complex-number section in number.c,

On Thu, 17 Jul 2008, PSPunch wrote: My primary goal is to place an object you can rotate by dragging the mouse. Ok, if it's through a user interface like that, for computing just one rotation matrix, I guess you could use [accumrotate] unless it accumulates too much error. Suppose that it consistently gets a relative error of 2**-24 downwards on every rotation. Then after 100 rotations it gets its values 6% wrong. If rotating using doubles (float64) instead of float32, then you'd hardly notice anything after 1 rotations. Note that this is just a rule of thumb of worst cases. It's better to try it. [accumrotate] doesn't try to compensate for rounding errors because they aren't quite significant in practice in this case. (it's possible to do the theory for figuring out average realistic error but it's easier and more accurate to just try the implementation.)

Re: [PD] vst~ again Status and Questions
Hey, I have used vst~ to great effect in PD before, and had no problem viewing the VST GUI interface... in fact I gave a workshop on basic synthesis for techno producers where I used all free VST's inside of PD, and PD as the routing/sequencing engine and it worked great. However I have no idea which version of PD I was on when I did that. I guess, the current version of PD-ext 1 year ago or so. ~David On Wed, Jul 16, 2008 at 5:39 PM, Luigi Rensinghoff <[EMAIL PROTECTED]> wrote: > > Am 17.07.2008 um 00:17 schrieb Thomas Grill: > > Am 16.07.2008 um 21:47 schrieb Luigi Rensinghoff: > > But i cant get the edit window to work (on XP) > > does your vst plugin have an editor at all? > I know there are some that don't work too well, but even those should at > least show up. > > No it doesnt show up ... nothing... > ...i think i can use plogue bidule for it.. but its a shame ;-) something pd > cant do > > is it supposed to work ?? > > yes, it usually does > gr~~~ > ___ > Pd-list@iem.at mailing list > UNSUBSCRIBE and account-management -> > http://lists.puredata.info/listinfo/pd-list > >>---< > Luigi Rensinghoff > [EMAIL PROTECTED] > skype:gigischinke > ichat:gigicarlo > > > > > ___ > Pd-list@iem.at mailing list > UNSUBSCRIBE and account-management -> > http://lists.puredata.info/listinfo/pd-list > > ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
[PD] Creating music notation with GEM
Hello, I have a question, how hard do you think it would be create a notation engine for GEM? What considerations would go into the design? On the simplest level, I'm imagining doing non-rhythmic notation to display chords and cells for improvisors. Since the number of notes on a chord would be determined on the fly, would it be better to create the max amount of objects and turn off unwanted ones, or better to use dynamic patching? This would simply be to create circles representing noteheads Here's my imaginary prototype: [gemhead] | | | [cell G Ab F# F ( or [chords c4 e4 g4 , F#4 G4 B4 ( or [cell 0 4 3 5 2 1 ( | / | / [treble_clef] Anybody have any idea what kind of messages I might send such an object? ~David ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
