[Andrew B. <an...@vo...>]

Thanks, that works.  (And looking closer, mangle.h was in my grep results  
for the various globals I was looking for.  I just managed to miss  
noticing it.)

Try __qq__source instead. The external global symbols in the interpreter 
are stropped with a prefix (see mangle.h, this is created automatically 
with the mangle.sh script) to prevent name collisions with shared libs 
linked with the interpreter.

[q-lang-users] Status on my attempt to port Q to amd64

[Andrew B. <an...@vo...>]

So...I've only had a few minutes here and there to play with this (it's on  
one of my computers at work, and this is not really for my job), but I  
feel like I've made some progress.  However, trying to debug a little, I  
quickly run into what might just be a gdb oddity.

Most of the interesting variables in the environment setup seem to be  
global, or at least external to the q.c file, and the "print" command in  
gdb tells me that there is <<No symbol "source" in current context.>>   
This is also the case for "outid" and "qpath" and seemingly lots of other  
variables.  As far as I can tell, they aren't macros.  Can anyone tell me  
why they are invisible to the debugger?

[q-lang-users] New q-faust module

[Albert G. <Dr....@t-...>]

Hi all,

For the DSP buffs around here: I've just imported a new module into Q 
CVS (http://sourceforge.net/cvs/?group_id=96881): q-faust. (Probably 
still needs some time until it shows up in anonymous cvs and the cvs web 
interface.) There is no file release yet (and I've only tested it on 
Linux so far), but if anyone wants to have a tarball (which also 
includes the SWIG-generated wrapper file, so you don't need Q-SWIG to 
compile it) just let me know and I'll send it to you.

The Q-Faust module lets you load and run Faust-generated signal 
processing modules in Q. Faust ("Functional AUdio STream") is a 
functional programming language for real-time sound processing and 
synthesis developed at Grame (Lyon, France, see http://www.grame.fr, the 
same guys who have also written MidiShare, which Q already uses for its 
MIDI interface) and distributed as GPL'ed software. Faust is based on an 
algebra which includes the necessary basic operations for describing all 
the usual kinds of block diagrams. It allows you to specify DSPs in a 
very concise and elegant manner. A closer description of Faust can be 
found on http://faudiostream.sf.net.

What this basically does: You can create your digital signal processing 
algorithms in the Faust programming language, compile the DSP to a 
shared module, and then load this module into a Q script at runtime and 
use it to process digital audio signals in realtime. The Faust compiler 
itself actually produces C++ code, and includes some clever 
optimizations, so that the generated DSPs can compete in terms of 
execution speed with carefully handcoded ones.

Right now only a simple test example is included in q-faust, but you can 
also use the *.dsp examples in the Faust distribution (which includes, 
e.g., a freeverb implementation and a Karplus-Strong synth) with the 
examples/faustui.q script to try it out (see the comments at the 
beginning of examples/faustui.q for instructions on how to do this).

Enjoy!

This is cool. I've had binary marshalling on my TODO list for a long

I made a few libraries for Q: json-q which is a JSON[1] reader and

Yes, everyone would be happy if Q worked on 64 bit, especially me. ;-) 
Thomas Pasch has been working on it for a while, but apparently he gave 
up for now. Maybe you can contact Thomas and ask whether you can work on 
this together. I'll try to help as much as I can, given that I don't 
have an AMD64 (yet) to test.

The readline library needs some terminal interface to work with, ncurses 
or something like that. I think that termcap might be a fallback option 
if nothing else is found.

But configure shouldn't attempt to build the bundled readline at all if 
you have it on your system. (You probably have, just make sure that the 
corresponding development package is installed as well.) If the readline 
header file or lib is in some non-standard location, you can use the 
--with-rl and --with-rl-includes options to tell configure where to 
look. See configure --help for a description of those options.

Yeah, libtool is a beast. ;-) But nevertheless it's still the only beast 
that I'm aware of which provides cross platform shared libraries/dlopen 
support.

Tcl does, Python does not.

C-Python has distinct 8-bit and Unicode strings as a result of legacy
considerations.  Jython has only Unicode strings as a result of being
embedded in Java, which also has only Unicode strings (and octet sequences
as a separate type).  In both cases, the Unicode strings are implemented
as sequences of 16-bit integers.

The TCL documentation at http://www.tcl.tk/doc/howto/i18n.html gives a
nice overview of the issues in converting to a UTF-8 internal representation.

[q-lang-users] LAC 2005

[Albert G. <Dr....@t-...>]

Hi, folks,

I'm just back from the 3rd International Linux Audio Conference 
(http://lac.zkm.de/) at Karlsruhe in Germany, and I must confess that we 
all had a *very* good time there. ;-) I also hope that I managed to drum 
up some interest on Q and its multimedia capabilities. Just in case 
there's someone interested in my presentation, I've made the paper 
available as a pdf in the documentation section of q-lang.sf.net. The 
direct download link is here: http://q-lang.sourceforge.net/q-lac05.pdf

(I didn't upload the slides, but if anyone wants to have them I can send 
them in private email.)

At the conference I also met with Yann Olarey from Grame (France) who 
has written a very cool piece of software: Faust, an FPL for doing 
realtime digital signal processing. I'm planning to provide an interface 
between Faust and Q in the near future, if anybody is interested in that 
or even wants to give a helping hand just let me know...

Cheers,
Albert

today. As you all know the current Q mascot is the poo-bear (sp?) on the 
black board, which I found in some obscure spot on the net, I just hope 
that I don't get sued for that. I thought it's nice. :) Any other 
opinions on that? Other suggestions?

Cheers,
Albert

Yup, that sounds like a good solution; no or negligible overhead for 
plain ASCII is a must. I think that's also the way that Python and Tcl 
do it.

Well, we'll also have to check the library modules. I guess that clib 
will be affected, as well as the GUI interface and some parts of the 
graphics modules.

Thanks for the offer, I'll get back to you on that. Unfortunately, right 
now I still have some new modules releases on my TODO list and then the 
6.1 version of the interpreter, while my intern is busy developing an 
OpenAL module. So this may take some time. :(

[q-lang-users] icon: powered by Q?

[Tim H. <q...@st...>]

Hi folks,

Do we have an icon for the above purpose? Could use something to stick on a
website or two :)

If not, I may try to wax artistic, but results of that are not necessarily
aesthetically pleasing ;)

[q-lang-users] Unicode

[John C. <co...@cc...>]

Albert Graef scripsit:

> functional programming language? ;-)

I'd be interested in helping you do it, and maybe peeking at some source
code here and there.  Overall, I'd say you're 90% of the way thanks to
two decisions about typing:

1) You don't have a character type in Q;

2) You already distinguish firmly between strings and byte vectors.

Not having a character type in Q means that you don't have to break any
assumptions about how big a character can be: in Unicode there are 0x11000
different potential characters (most of them unassigned), not 128 or 256.

I recommend that Q strings use the UTF-8 encoding internally.  The UTF-8
encoding uses 1, 2, 3, or 4 bytes to encode each character depending
on the numerical equivalent of the character.  In particular, the ASCII
subset uses a 1-byte representation, the same as ASCII itself, and the
bytes 0x00 through 0x7F are never used for anything else.  The Latin-1
subset, however, requires a 2-byte representation.

There will be five places where Unicode has to be addressed:  in pulling
substrings out of strings, in reading, in writing, in converting from
strings to byte strings, and in converting from byte strings to strings.
In the last two cases, it is desirable (but not necessary) to provide
a method of overriding the system standard external encoding such as
Latin-1 which is generated or interpreted respectively.

The iconv_open(), iconv(), and iconv_close() functions do the donkey
work of conversion.  If they are not available on a system, the GNU
iconv library provides a good implementation.  It's distributed under
the Lesser GPL, so it will not affect the licensing of Q.

I understand.  I hope the above is somewhat helpful; I'll be happy to
answer questions either on this list or privately.
