there is nothing linux/osx specific in the code on Gem's side, and the
dylib code is abstracted away.

in theory(!), you should be able to use frei0r plugins from within Gem
on w32, as soon as you can get hold of a frei0r plugin compiled for w32.

maybe you can help us a bit.
e.g. by:
- - telling us which OS you are using
- - which Pd?
- - creating a _minimal_ patch that triggers the problem
- - what get's printed to the pd-console before the crash? what get's
printed to the console?
- - what if you raise verbosity to level 2?

[PD] getting console output when Pd crashes on w32 (was Re: [PD-announce] gem 0.93.1)

never!

i think this has been mentioned on this list a couple of times, but
let's do it again

you ought to start Pd from the cmdline/shell/CLI (the thing you get when
you do "Cmd-R" and start the "cmd" program), use "pd.com" (rather than
"pd.exe"), give it the "-stderr" flag (so it won't print to the
pd-console but to the console instead), and eventually add "-verbose
- -verbose" to the flags.
something like:

$ C:\Programme\pd\bin\pd.com -stderr -open patch.pd 2> pd.log


this will print everything into a log-file "pd.log".
once you triggered the crash, the pd.log will still be their and ready
for future inspection.

no need for a .bat file.
.bat files are their for convenience, so you don't need to reiterate
simple tasks.
let's hope that you don't need to debug so often, that you need a
convenience framework for that.

just add "-verbose -verbose" (that's 2* "-verbose") right after ther
"-stderr"...

personally i do think that any fixed limit is going to impose troubles.

afaict, the main idea here is to provide an easy to use API, combined
with some performance.

somebody _will_ reach your hard limit, and i think that telling them to
either switch from the "foolproof API" to "export mode" or to redesign
their patches just because they called "add_element()" once too often
will not do.

why not simply resize the internal array as needed, starting with 32
elements and doubling whenever the limit is reached?

thanks.
the pd.log doesn't do much, but pdVV.txt shows a bit.

#1 are you sure that this is Gem-0.93.1, and not Gem-0.93.0?
(in 0.93.0 the splashscreen would show "0.91.CVS", i thought i fixed
that with 0.91.1)

#2 afaict, you get the crash while loading your patch (even before any
loadbang might get evaluated); the problem might be related to ImageMagick

therefore:
could you try to move the "gem_imageMAGICK.dll" out of the way?
(effectively disabling this plugin).
does it still crash?
if this fixes the problem, you could try to re-install Gem and
de-selecting "imageMAGICK" and instead selecting "imageQT" (which will
use QuickTime for imageloading) or "imageJPEG", "imageTIFF" and
"imageSGI" (which will use the image loaders you had in older Gem releases)

if it does not fix the problem, what do you get if you add "-noprefs" to
the startup flags (logfiles please)?

let's rephrase:
Gem-0.93.0 would display "0.93.CVS" whereas Gem-0.93.1 should display
"0.93.1"
therefore i ask whether you are sure that you are using 0.93.1
(try to re-download the installer, it might have been fixed 5 minutes
after the initial upload)

i just want t omake sure that we are definitely working on 0.93.1

that was a bit too optimistic:
i meant "-noprefs -lib Gem" (so we only have Gem loaded and no other
library)


and please always use "-verbose -verbose";
the non-verbose logs are virtually useless.

so could we try that again?
for simplicity, could you move _all_ plugins into a disabled/ folder (or
rename all of them; or delete all of them), and then post the verbose2
logs (and -noprefs -lib Gem ...)

if doing that on a real network with OSC-over-UDP (which i assume as
well, as it is the default), you will soon get into problems: even with
jumbo frames turned on, the maximum frame size is 9000bytes.

i am not aware of an OSC implementation that can increase the packet

do you remember the actually used packet size?

well, start form your patch and remove everything that is not Gem.
then copy everything left into a flat patch.
then remove entire gemchains until only the one that causes the crash is

then remove objects from this gemchain until only the objects needed to

with "preload" you mean, sending a "font /path/to/my/valid/font.ttf"

thanks for doing a bug report.
with "all the information you have", i meant "ALL the information you
have", which things i asked so far, like:
- - operating system
- - gem version (it's obvious for us now, but the bug report is not
directly linked to this email thread)

there are 2 cases here:
- - "zexy aliasing internal objects" applies (afaik), only to [pack] and
[unpack]; the policy is, that they ought to be compatible, but enhanced
versions of the original objects.
since in fact they are not, the shadowing of the built-in objects is
currently disabled, and you can only access these objects via
[zexy/pack] resp [zexy/unpack])

- - "internal objects aliasing zexy": this is more likely ([abs~] and
[wrap] come to my mind); the policy here is, to keep the old zexy
behaviour as long as this "enhances" (aka "adds to") the original behaviour.
if the internal object had an added feature, i would most likely add
this feature to the zey object (though this never happened, afair).
if the internal object breaks compatibility, i will most likely keep the
original zexy behaviour (unless the break is indeed a bugfix); afair,
this has not happened so far.

afaict, roman has an old version of puredata installed (0.42.6-2), which

i think it might make sense to conflict with "puredata (<< 0.43)"

and if you worry about playing backward, then you should simply modify

what exactly is it that you don't understand?

the "weighted" elements take the luminance of the blobs and interpret
them as 'mass': this mans, the brighter a pixel in the blob gets, the
more important it is.
"centerX(weighted)" is the X coordinate of the centre of gravity,
"size(weighted)" is he total 'weight' of the blob,

the 'unweighted' elements, are mere 2D geometric properties, "minY" is
the minimum Y coordinate of the blob, and "area" is a (normalized) count
of all pixels covered by a blob.


> I know [pix_multiblob] makes a matrix to get the results, but I
> don't know how does that work neither.

a matrix is a 2D array of N*M elements to store numbers.
N is the number of rows in the array, in our case the number of detected
blobs. M is the number of columns in the array, in our case 8
(centerX(weighted)...area)

the iemmatrix library deals with these arrays (if you don't want to
parse the simple message yourself)

so if you want your patches to be included into Pd proper, then they
must (legally) be BSD3.

any patch for puredata posted to the patch tracker, is silently assumed
to be BSD3 my miller (see the list archives for his quote) unless
explicitely stated otherwise.

modern kernels don't have v4l(1) any more, hence pidip has been compiled
without pdp_vloopback, but somebody forgot to remove the call to its
_setup function.

just a wild guess though.

no, you get the position of the "current" element.
if you watch the output of [gemlist_info] closely, you will notice that

i guess, with "portable" you mean "put on a USB-stick and it runs on any
w32 machine" and not "portable to FreeBSD, BeOS and CPM".

in this sense, Pd-vanilla is portable out of the box. download the zip
file, unzip it onto your USB-stick and move.

i guess that Pd-extended would be portable as well, if there wasn't an
installer :-)
you might have luck by downloading the Pd-extended, run it on your
machine and let it unpack into %ProgramFiles%\Pd-extended and then copy
the entire contents of this folder (%ProgramFiles%\Pd-extended) to your
floppy disk.

the binary is called "pd.exe" and lives in /bin/

the linux "equivalent" that is currently part of Gem is a V4L/V4L2
output module, by use of a loopback kernel driver ("vloopback" for v4l
support, v4l2loopback for v4l2 support).

this allows you to "send" pix-data to virtually any application that is
ablt to read v4l/v4l2 devices (it's only "virtually", since some
applications make weird assumptions about the video-device...e.g they
will abort if no tuner is present)

the good thing is, that the receiver side need not care whether the data
is coming from a webcam, a high end grabber card or an application.
(e.g. you don't need "syphon" support on the client)

it depends on your actual problem, whether this is an issue or not.
e.g. if you want to do image analysis on the client side of a "raw"
image from the server, then you might be better of without taking the
detour via the gfx card.

if however, you want to do something with (say) Gem's "output" (which by
it's very nature is already 'on' the gfx card), then a main memory
based video-piping mechanism might add significant overhead.

i figure this is pd-vanilla (afaik, there is no 0.42-6 for Pd-extended);
in debian there is also a 0.43 version of Pd available, which has a
number of improvements regarding jack support (don't know about mint though)


> "JACK Audio Connection Kit - Qt GUI Interface
> Version: 0.3.6"

wow, that's old. my jack is 1.9.7 (which is actually jack2; the jack1 i
could install on my system is 0.121.0)

> [and yes, it is in fact running. Works just fine with ChucK.]

well, so let's get to the real problem.

your error log seems to indicate, that jack is not running when you
start Pd.
please make sure that jack does run, before you start Pd.
make sure that you don't have any "opposing" settings (e.g. use
"-noprefs" when starting Pd)
make sure to tell Pd how many channels to allocate for Pd (e.g. use
"-jack -channels 8" when starting Pd)
this works fine on my debian/sid machine.

3 things:

#1 Gem is C++, as well as it's plugins. because of name mangling, you
cannot mix C++ binaries compiled with one compiler with binaries
compiled with another compiler.
e.g. if Gem was compiled with M$VC (which it was if you are using the
binary provided by me), you will not be able to use plugins compiled
with MinGW

#2 the "installers" (both the zip-file and the installer executable)
provided by me should include imageQT, imageJPEG, imageTIFF, imageSGI
(and the notorious imageMAGICK); the installer.exe has the imageMAGICK
plugin chosen, and the other plugins de-selected (i think), but you can
simply select the plugins you want. the zip-file contains all plugins
(including the faulty imageMAGICK)

#3 finally, the problem you reported here is a bit different, a it seems
it fails to link the plugin alltogether (regardless of whether you will
be able to use it with the Gem.dll, as explained in #1); in order to fix
this (which might be interesting on the road to make Gem compilable on
MinGW alltogether), i would need a bit more information (e.g. configure
flags, configure output, build log)
if you are interested, you could try to join the gem-dev [1] mailinglist

it seems like you are trying to compile pdgst with an older version
(<0.93) of Gem.
it also seems like pdgst currently only builds with Gem>=0.93

i hope i find time to make pdgst backward compatible.

if you use the installer executable from Gem, you will presented with a
dialog (during installation; it's the 3rd page) that lets you choose
which components you want to install.
if you navigate to "plugins->image", you will have the option to choose from
- - ImageMagick images
- - QuickTime images
- - SGI images
- - JPEG images
- - TIFF images

de-select "ImageMagick", and select the plugins you want.
traditionally, Gem came with the SGI, JPEG and TIFF loaders, so i you
want the same image loading capabilities like in the old days, only
select those 3 plugins.

the ImageMagick plugin obviously makes problems on w7 (i only tested on
XP), for the QuickTime plugin you need QuickTime installed (else you
will unfortunately get side-effects)

the idea is, that [symbol2list] breaks a symbol into a list of _atoms_,
which are then evaluated the same way as ordinary lists (though i'm not
sure whether it is implemented that way...)

e.g. is you create a message [list 00 ab 87 02( the 1st and last element
of the list will evaluate to numbers (and thus "lose" their leading zeros).
does this come unexpected to you?

however, it might be worth considering a "symbol only" mode of the
object, that will never try to convert a token into a number but always
keep it a symbol.

> not accidentally losing zero's?

btw, you are not "losing" any zeros.
whether your pay cheque says "100,-€" or "100,-€" does not
make any difference, when it comes to buying your marmite. those numbers
are exactly the same.


if you need "00-ab" to split into two 2-character strings "00" and "ab"
and want to use [symbol2list], you could simply convert all the numbers
you got to 2-char strings by using [makefilename %02d]

no.
my suggestion was to use the msgbox instead of [list2symbol :], not for
the entire formatting. you still need to use [makefilename]

if you use [list2symbol :] without first formatting the numbers using
[makefilename], you will get "1:34:45.345" as well.

i was going to say: you can change the samplerate of Pd to 48kHz using
the Media->Audio menu. it will magically shorten each sample from
(1/44.1)ms to (1/48)ms, so you don't need to worry about that.

but then, maybe you meant your soundfiles?

[PD] [PD-announce] gem 0.93.2

2011-11-10 Thread IOhannes m zmoelnig
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

i'd like to announce a pre-release of Gem-0.93.2

this is the 2nd bugfix release in the 0.93 series.

like always we have fixed numerous bugs and features, and most likely
introduced an equal number of wishlists and showstoppers.


noteable differences since 0.93.1:

availability:
- - this is the first 0.93 release, that provides binaries for OSX.
the downloadable archive contains fat binaries for both ppc and i386
which should run on any OSX since 10.4

functionality:
- - fixed a crashe on 64bit architectures related to SIMD-detection code
- - fixed other crashes on 64bit architecture of some pix-effects (Pete's
Plugins)
- - pix_texture now handles repeat/quality of external textures
- - failing plugins no longer keep other (working) plugins from functioning
- - improved filmGMERLIN framecount behaviour
- - made recordQT work again

documentation:
- - a number of typos and inconsistencies in the help patches



drawbacks:

w32: the current w32 build has been compiled as "0.92.3" rather than
"0.92.2"; i'll hopefully be able to compile a corrected version tonight
and upload it then

OSX: it seems that Pd-0.43 quits as soon as Gem is loaded.
this only happens if you start Pd by double-clicking the application; it
does not happen if you start Pd via the cmdline.
older versions of Pd (0.42 and prior) are not effected.
both Pd-vanilla and Pd-extended are effected.
if you want to use Pd-0.43, the suggested workaround is to start Pd/Gem
from the cmdline (ouch!)
if any help is welcome



get happy!

funnily enough i noticed it too a couple of minutes ago, but had more

i now investigated, and it turned out to be a side-effect of disabling
outdated search-results of gridflow (see some mails on the "list2symbol"

it should be back to normal.

you could also just use /downloads/ which will redirect you to the

if it shows "0.92.3" than it most likely is 0.92.3

elaborated guess:
Gem does a bit of path magic to be able to access its own abstractions.
this means that it adds it's own path to the list of search paths of Pd.
if you then manually edit your search paths and save, you will end up
with a hardcoded path to the currently installed version of Gem.
if you now install a new Gem into a different location, you still have
the old search path stored in your preferences, and Pd is likely to look
there first, thus finding and loading the old Gem!

short fix:
open your "Path"-preferences and delete all references to the Gem-paths.
save.
restart Pd

to texture coordinates.
S, T, U and V are the standard names for texture coordinates in the
literature, just like X, Y & Z are standard names for 3d coordinates and
R, G & B are standard names for colors.

the reason why the help-file doesn't mention much more, is that it would
become impossible big.

i think a basic understanding from what [pix_coordinate] does can be
guessed when playing a bit with the help-patch and feeding it with your
own values.

darn.

the actual code has not changed so much, but now it is factored out into
separate files.
so in theory everything should still be working.

one major improvement is, that we now have a consistent interface
between all platforms (w32, linux, osx), that allows for enumerating and
setting of devices and device properties in a unified way.

i suggest playing a bit with the pix_video-help patch, with a focus on
the [enumerate( and [device( messages.

what do you get?

tyr running Pd with "-verbose -verbose", preferably from the cmdline,
and post the full output of both the Pd-console and the console. [1]

sorry for talking gibberish.

i don't know much about Pd-extended and little about w32.
i'll give it a try though:

$ pd -stderr 2>&1 | pdsend  localhost udp

this basically means:
- - take the output of Pd, and send it (using pdsend) to port  of the
local machine.

the 2nd part of the line ("pdsend  localhost udp") should be fairly
obvious: it calls the pdsend program (on w32 it is called pdsend.exe and
you might have to find out where it is - somewhere in the Pd\bin\ folder
is a good guess), with some parameters, that specify the target port
(), the target host (localhost, the machine the program is executed
on) and the protocol (udp).

the 1st part is a bit more complicated, i'll come to it later. it
basically grabs all messages printed by Pd.

the fun part is in the middle, "|" (aka 'pipe') takes the "output" of
one program (in this case Pd) and uses it as "input" to another program
(here: pdsend)


the slightly unorthodox part is the 1st one:
we have to make Pd produce it's output in a form that is usable as input
for pdsend. this basically means that instead of sending the printout to
the pd-console, we have to redirect it to a special output, that is
called "stdout" (pdsend will read from "stdin", and the pipe ("|") will
magically transform the stdout of the 1st program to the stdin of the
2nd; see [1] for more information)
Pd usually send s it output to the Pd-console.
however, you can start it with a special cmdline flag, that will all
messages to a special output, the "stderr" (see [1] again).
if you start Pd from the console (the cmdline; on w32 this would be e.g.
the "cmd" program), all messages sent to the stderr will show up on the
console (note, that on w32 you will have to start pd.com rather than
pd.exe, because else windows will prevent the stderr to be printed to
the console).
this is almost what we want (we are sending Pd's printout to some
standard stream!), but we are not there yet (Pd sends to "stderr",
whereas we want it to send to "stdout")

luckily enough, many cmdline interpreters have a special syntax for
redirecting stdstreams. on bash (a common cmdline interpreter on un*x)
and afaik on w32, you can do redirect the stderr of a program to the
stdout using "2>&1" (stderr has a numeric file descriptor 2; stdout has
a numeric file descriptor 1; so this redirection means: take
filedescriptor 2 (stderr) and send it to filedescriptor 1 (stdout))

so the line i gave means:
"pd" - start Pd,
"-stderr"- but send all printout to stderr rather than the pdconsole
"2>&1"   - then redirect the stderr to stdout,
"|"  - pipe the stdout to the stdin
"pdsend ..." - of pdsend, which will send the data (back to Pd)


hope that helps.

wouldn't it be easier to use a syntax like
[get  ( ?
rather than [get  (

i think sending the rcvname first will make the syntax more easily
extendible.
e.g. it would allow for [tryset   ( and
the like.

do the binaries from http://gem.iem.at work?

Gem still doesn't work in OSX/64bit, but as long as OSX10.7 has a 32bit
compat layer and you have a 32bit Pd there shouldn't be a big problem.

if there are 10.7 autobuilds then they are likely to either contain only
x86_64 builds (which should fail to load a 32bit external like Gem) or
they are fat builds including 32bit and 64bit, which will probably
launch another instance (in 32bit compat mode) of Pd when loading Gem.

iirc, the xeq approach was more like having multiple objects connected
via a "filehandle" like thing; so you could have an object that just
opens the file, and another objects that would seek within that file.

while i'm all for "one objectclass per functionality", and for
establishing a single idiom (at least, per "objectclass family") - and
thus think i'm with hans also, i still don't see any point in
"masquerading as a single class".

what makes the name [list foo] any better than [listfoo]?

i don't know. my native language allows construction of compound words,
and while this seems ridiculous to many english speakers, it's not that
it makes a lot of problems in real world.

for unknown reasons, it seems that [text file] seems to work for lots of
people.

and i argue that it's a bad idea to introduce whitespace as namespace
delimiter in a language that already uses whitespace as token/atom
separator.

i cannot remember any other complang, that uses whitespace as namespace
delimiter, most likely because virtually all languages already use
whitespace to separate tokens.

it wasn't meant to be offensive (in case you read it like that).

i think that [receives] is a great name for a "multiple receives" object.

however, i think that the "prefix" functionality of [receives] (which is
very present, being the 1st argument) is a bit confusing in this context.
for me, the name [receives] would be great, if you could use it without
having to the prefix (and no, i don't think that using [loadbang]->[foo
bar(" is a proper replacement, nor [recevies, foo bar])

english speakers usually don't encounter these "compound words" since
they (the words) are not used in their (the people's) everyday life.
thus i assumed that these compound words do not impose any problems for
those people (unless they are communicating with germans that keep
glueing words together)

german speakers have to deal with these words on a day by day basis, and
for them it usually does not make a lot of problems in their real world.

in the default use case, [pix_texture] transfers image data from main
memory to GPU memory, so all subsequent actions involve GPU only.

so to answer your question: pix_texture does not run on the gpu but is
the bridge between cpu and gpu. that's by definition. it's hard to do
anything about it.

if you want to use the same texture for multiple Geos, you should put
the [pix_texture] outside of the iteration, so you ensure to only once
transfer the image to the GPU and then use it however often you like.

you can also use a GPU-based texture generated by one [pix_texture]
within another [pix_texture] by using their 2nd iolets.

#1 do you think "path" is a good name, or will people confuse that with
"getdir"? probably [searchpath] would be more meaningful.

#2 how does this object relate to the quest to eliminate path settings
alltogether? i thought "-path" is really only for nerds like me who feel
unable to use standard paths :-)

#3 could anybody tell me why [declare] does not take immediate effect?

so why is [import] not called [lib]?

while i beg for consistency myself, you must not forget the context
where things appear. "path" in the context of starting an application
can well mean something different than in the context of creating a
programme, dealing with sound files.
also i would not mind renaming the "Path..." to "Search paths..." in the
prefs panel (i would object in the startup flags, for compatibility reasons)

this question was not a technical one. i understand the implementation
and its implications pretty well.
nevertheless, i find the behaviour confusing and unintuitive.
to rephrase my question:
#3 could anybody tell me, why [declare] is implemented in a way that it
doesn't take immediate effect?

i'm not saying that "import" is a bad name. actually i think it is a
good name.
i'm only saying that "path" might be a sub-optimal name. e.g
[split_path] won't split the "path" you are talking about in  [path],
though the consistency suggests it.

otoh, your argument about the labels in the prefs are a bit void, given
that they are meant to be translated.
i don't see much consistency if "Pfad..." refers to the same as [path],
but [path] and [split_path] are unrelated.

actually i don't see much problems here.
if i create a patch with a [loadbang]->[; pd quit( then the patch will
behave differently during creation time (it will do nothing) and during
runtime (it will quit Pd).
if i want to have the effect at creation time, i can manually bang
whatever is connected to [loadbang].


otoh, when i add [declare -path foo/], this is usually because i found
out that a certain path is missing, and i cannot proceed with patching,
until that path is added.
the current situation makes it really complicated for people who had no
clue what they wanted to do when they started Pd.

i was talking about binary packages as well.
maybe i missed some point though.

if you are asking how to _properly_ install a package without root
priviliges, then i believe that this is impossible, given that the very
nature of "properly" installing a package means writing to parts of the
disk where unproviliged users are not allowed to write to. that's by design.

anyhow, in my personal experience not many packages will actually
execute any scripts in the pre-/postinstall process; e.g. of the 3600
packages installed on my system, only 1800 come with a postinst script.
of those, at least 900 are virtually the same and only call "ldconfig"
(after installing a library).

if the package in question indeed contains a preinst/postinst script,
you can extract that with
$ ar x pd.deb
$ tar xvzf control.tar.gz
$ ls postinst

what i mean is, that most pre-/postinstall scripts deal with either
easing the upgrade of a package (e.g. configuration files need to be
migrated) or making the system aware of updates within the package (e.g.
tell the linker cache that new libraries are there; install system wide
menu entries).

the former is no problem if you don't _upgrade_ your package.
the latter could be helped by rebooting the machine.

i didn't say anything about the content of the remaining 25% (mainly
because i though i had better things todo than to check the postinst
scripts on my system); esp. i did not want to imply that 25% of my
packages have postinst scripts that do significanlty more than calling

"explicitely calling destructors" is a bit vague in this context. you
question should rather be termed: "is it considered 'good practice' to
explicitely call destructors on exit".

anyhow, i believe "good practice" depends on a number of factors; so you
cannot simply say that using CamelCase is good practice whereas using
hungarian notation is bad practice.

personally, i prefer if the program does call dtors on exit, since there
are a number of ressources that cannot be automatically freed by the
operating system due to their very nature. if your Pd-patch controls the
facilities in your flat, you might want it to shut off the light if the
patch is powered down in order to save energy. the operating system most
likely will not send the appropriate commands to your arduino

oh yes of course.
seems like i was not fully awake.

anyhow, i assume that jean-christophe meant something like "atomic
objects that cannot be opened by clicking on them" when he was talking
about "objects".

if you are new to [gemwin], you might want to checkout the help-patch of it.

it should mention something along the lines of "view".


for your 2nd problem you might want to have a look at the
examples/02/*snapshot* patches.
in short [pix_snap(2tex)], [pix_write(r)] and [pix_record] are the key
objects here.

definitely not.

Gem always needs to find the truetype font in order to be able to render
a text. it will look for the default font "vera.ttf" in all search-paths
of Pd, including the the patch's home.
