multiple float outlets
by Jeffrey Hildebrand 19 Sep '03

19 Sep '03

i was reading the external HOW-TO which is great, but i'm having trouble creating multiple float outlets. x->x_obj can only store one pointer, so what do i have to do? am i supposed to make a new t_object for each float outlet that i want? thank you for the help! scott

external perform question
by J. Scott Hildebrand 18 Sep '03

18 Sep '03

right now i'm trying to implement a headtracker, and i need continuous float output. by using a signal processing external i had before i can print the headtracking info to the console but i haven't been able to output a float from an outlet. can i have perform functions in standard non-signal processing externals? scott -------------------------------------------------------------------- "640K ought to be enough for anybody." -- Bill Gates, 1981 --------------------------------------------------------------------

another key binding bug using Tcl 8.4.1 on OSX
by Hans-Christoph Steiner 18 Sep '03

18 Sep '03

So I can't do a multiple select using the mouse and the Shift key on OSX. I also tried Ctrl, Alt, and Cmd and none of them let me do a multiple select with the mouse. Does this work for anyone else? I am currently using Tcl 8.4.1, but I'll try this on 8.4.4 and 8.4.2 when I get a chance. .hc

removing class_sethelpsymbol()
by Hans-Christoph Steiner 18 Sep '03

18 Sep '03

So now that there are a plethora of externals that need their class_sethelpsymbol() changed to be 0.37 compatible, I am wondering whether we could just remove it completely. In the process of looking into this, I noticed that none of the GGEE objects have a class_sethelpsymbol(). So what, if any, are the downsides of just removing class_sethelpsymbol()? It seems to me that it would save us a lot of regexing and #ifdef'ing. .hc

scriptable/makefile-able Windows installer
by Hans-Christoph Steiner 18 Sep '03

18 Sep '03

My experience with created a Makefile that builds a very complete MacOS X Pd Installer from CVS just by typing "make" has inspired me to start thinking about doing the same for Windows. But I have basically no experience with MS Visual Studio and don't really want to learn it. But I am willing to try to write an nmake Makefile if its similar enough to make Makefiles. Then there is a question of which installer to use. I figure there has got to be a way to do this using free tools like Nullsoft's SuperPiMP (http://nsis.sourceforge.net/site/index.php ) or Inno Setup (http://www.jrsoftware.org/isinfo.php ). But my big caveat is that it would have to be able to be built entirely by a Makefile. I don't want to have to go into a GUI app in order to create the installer. Anyone know anything about these or have examples? Anyone want to help? This is not an immediate project for me, but probably this fall or winter. I just wanted to get the idea out there. .hc

no key commands in 0.37/MacOS X
by Hans-Christoph Steiner 18 Sep '03

18 Sep '03

So I have noticed in the past few releases of 0.37 (it may have existed before, I just don't remember) that the key commands don't work in MacOS X. I am currently using pd 0.37-test 11, Tcl/Tk 8.4.4, and MacOS X 10.2.6. It doesn't work for me with either Ctrl or Cmd... and it certainly slows you down when you have to go to that 'Put' menu all of the time. Is anyone else having this problem? .hc

get_sysblksize() and overlapping
by Tim Blechmann 17 Sep '03

17 Sep '03

hi all, i'm experiencing some strange behaviour with get_sysblksize(). when running this function in an external that runs in a subwindow with overlapping, this function returns the blocksize/overlapping, but not the blocksize... is there another function for the blocksize or will i have to edit it manually? thnx...

preserving connections of 'bogus' objects
by Krzysztof Czaja 17 Sep '03

17 Sep '03

hi all, sorry for a longish post, and for dealing with what is surely not a high priority feature... Anyway, I will gladly hear from other devs about their views. What I have in mind, is that during object creation, when the requested class is not known, and there is no matching abstraction, a `failsafe' replacement object is used. Currently in Pd, it has never any inlets nor outlets, even if loaded from a patch with the original object connected. (A slightly different case, and apparently easier to deal with, is an already patched up object, edited into a ``couldn't create'' nop by the user.) Currently in Max, such creatures, called `bogus' objects, do preserve connections. The newest cyclone's import feature creates connection-preserving replacements of all unknowns. The implementation is pretty straightforward: . for every object of unknown class, create a bogus having as many inlets and outlets, as any sane object is ever likely to have; . then, after the entire binbuf representation of a file has been evaluated, broadcast a request to all newly created bogus objects, making them adjust both their ports (delete every inlet/outlet right to the last connected one), and their text (delete the '_port.bogus' prefix). For details, search for 'bogus' in miXed/shared/common/port.c in cvs. This is simplistic, in a way, but I would rather avoid an additional parsing pass through the binbuf, and avoid maintaining an auxiliary data structure. In the cyclone's case of an import-only mechanism supplied by an external library, the tricky part is to support the actual notion of an ``unknown class''. This is not just a class not yet defined, but such, that is also going to fail an attempt to load its library and abstraction files. Maintaining a specialized replacement of the binbuf_eval() routine would have been an even bigger evil, so I had to fake it -- by blocking all possible library/abstraction loading attempts from within binbuf_eval(), i.e. by temporary marking as `bogus' (during Max-to-Pd binbuf conversion stage) all objects of not yet defined classes. Thus, in the import-only implementation, the library/abstraction loading attempt is always performed in the constructor of a bogus, which, in case of a successful loading, transforms itself into a `reclaimed' object proper. However, for every reclaimed object, in order to get rid of a '_port.bogus' prefix, a temporary `hook' has to be created, then invoked, and finally destroyed... (Btw, this part could have been less clumsy, somewhat, if there were bindlist traversal routines in the API.) In short, it seems to work, but I have a vague feeling, that a general mechanism would be much simpler (and more useful too). Otoh, without more research, I have a feeling of having too narrow a perspective for just starting to mess with Pd's way of creating objects. Krzysztof
