hi list, I wrote a simple UI in tk, and i want to attach it to pd.
i tried:
[wish ui.tk( | [shell] | [route mypath ...] | ...
but i have a question: does this has sense? i see i takes about 5~10 seconds to load another instance of wish
if it could be possible to re-use the existing instance of wish used for pd-gui, the load would be immediate
is this possible? is there some ready-to-cook code that wraps a tk app into an external? that would be awesome :9
You can do that with the toxy lib, I believe [widget] and [tot] are the objects you want. They are included in Pd-extended.

ah! I already seen that, and forgotten about that.
In the last hour I read all available docs at: http://suita.chopin.edu.pl/~czaja/miXed/externs/
but still something isn't clear to me, also looking at the example widfiles
in addition I tried to port my app to toxy (see attached file), but it goes in an endless loop (resizing the pd window) withouth giving errors, so I am unable to debug it...

Ah, btw, I need to make an external that will enable writing server-side externals in the tcl language (Toxy is client-side only).
Do you want to give me a hand making/designing this?

eh me too, i discovered delays of toxy when dealing with messages that needs to be timing-accurate

yes! (as I said you on IRC) let me know some newz ;)

Ok, if I'm not staying too long in Toronto, we're having a developers meeting tomorrow at Ottawa university (matju + _heri + alx1) and we're going to talk about GridFlow II. Then I'd like to make a prototype of that external as soon as possible, possibly using SWIG; _heri has gained quite a bit of experience with SWIG. Once we have something that works I'll make you try.
However, there's a slight chance that we back off from that project (of making an external for server-side tcl), so I don't really want to promise anything tonight.

maybe Toronto's nights are too late for me :) if you came on IRC early I would be happy to hear (or partecipate) to te discussion
til now, I have a question wich didn't make me spleep tonight: also GridFlow is affected by those client/server issues?
does GridFlow run in the client? cause i'm experiencing timing problems. withouth making a too long explanation, i have:
[metro] | [# some operators] | [#export_list]
and it's totally inaccurate (with cpu load at 5~10% its clearly audible that messages or whatever are off-time)
can't wait for the dev meeting :)
bye bye

The meeting is in Ottawa... it's just that I was setting up a GridFlow-based exhibition in Toronto at Glendon Gallery.
Toronto, Ottawa, Montréal are all in the same timezone though.
The meeting was today and just ended. I didn't respond much on IRC because we were busy at it.
if you came on IRC early I would be happy to hear (or partecipate) to te discussion
The meeting was not on IRC. Tomorrow we're meeting again because I just agreed to stay one more day in Ottawa. Further meetings will be on IRC.
til now, I have a question wich didn't make me spleep tonight: also GridFlow is affected by those client/server issues?
only to the extent that GridFlow does GUI, but that's only the [display] class.
does GridFlow run in the client?
No, except part of [display], part of [peephole], the tcl/ruby evaluators, and the GridFlow menu.
and it's totally inaccurate (with cpu load at 5~10% its clearly audible that messages or whatever are off-time)
This might be due to the garbage collector, which has to run once in a while and takes some time (e.g. 25 ms once every N seconds). Those timing issues are the 2nd most important reason to switch away from Ruby.
The Tcl language doesn't have a garbage collector, so this problem cannot happen. The Python language (which was another possibility for me) has a garbage collector which is faster than Ruby (because it relies on being combined with a reference-counter).
can't wait for the dev meeting :)
I'm sorry that this meeting doesn't happen on IRC.

ah, nevermind that
it seems i have discovered the source of problems... my video acquisition card is generating strange warnings about IRQ....
bttv0: IRQ lockup, cleared int mask [bits: FMTCHG* VSYNC* HSYNC* OFLOW* HLOCK* VPRES* 6* 7* I2CDONE* GPINT* 10* RISCI* FBUS* FTRGT* FDSR* PPERR* RIPERR* PABORT* OCERR* SCERR*] ... bttv0: IRQ lockup, cleared int mask [bits: HSYNC OFLOW VPRES I2CDONE*]
cause without loading the bttv module my patch seems to work ok. so sorry for allarmistic bug spam :)

I also use bttv cards and I sometimes found that [metro] and [fps] don't agree even when the CPU usage is less than 100%. It varied in irregular, hard-to-predict ways. I mean, for each [metro] rate, it's stable (except for Ruby's garbage collection), but sometimes lowering the [metro] rate makes the framerate slower instead of faster. I haven't seen that in the last two years though.

If you are going to add Tcl support, I highly recommend that you check out the loader functionality that Thomas wrote. Its in both devel and MAIN, and there is a working CLR version working. I am thinking you could implement a Tcl loader and Pd API layer, then you'll be able to write regular Pd objects directly in Tcl.

I can already write regular Pd object-classes directly in Tcl or Ruby, thank you very much. I can name you two hundred (200) classes that were either implemented in Ruby or wrapped as Ruby using SWIG or source_filter.rb.
Thomas's loader does not enable other languages for externals; pd already allowed this by itself for very long, even though PyExt didn't seem to allow any class name other than [py] last time I checked. Thomas's loader is only about giving equal opportunity to pd's search path and incremental loading, and while this is something I like a lot, there are other priorities.
How do I detect whether a given version of Pd supports that feature or not?
