Re: s7, simple listener

Bill Schottstaedt — 2013-05-16T10:56:25

I think you need to add -ldl:

gcc -o doc7 doc7.c s7.o -lm -I. -ldl

The default gcc version of s7 now includes the dynamic loader,
but I (of course) forgot to check the documentation examples.
I need to find a way to extract those examples and run them
during my huge regression test suite.  Thanks for the bug
report!

s7, simple listener

James Hearon — 2013-05-16T01:50:27

Hi,
Trying to run the simple listener example from s7 manual under FFI.

$ gcc -c s7.c -I.

ok.

$ gcc -o doc7 doc7.c s7.o -lm -I.

s7.o: In function `g_load':
s7.c:(.text+0x4a177): undefined reference to `dlopen'
s7.c:(.text+0x4a192): undefined reference to `dlsym'
s7.c:(.text+0x4a1b6): undefined reference to `dlerror'
s7.c:(.text+0x4a1e9): undefined reference to `dlclose'
s7.c:(.text+0x4a1f0): undefined reference to `dlerror'
collect2: error: ld returned 1 exit status

I tried just including dlfcn.h in s7.c but that didn't fix it.  Wondering what lib or headers I'm missing.  I do have a ld-2.16.so in usr/lib if that's what it needs.

thanks,
Jim Hearon

gtk snd listener

Bill Schottstaedt — 2013-05-13T20:41:54

I'm unicodizing the gtk version of snd's listener, so if you
use the cvs stuff or the daily tarball, expect the unexpected.
I'll have it back to normal in no time...

Thank you both!

Re: optional arguments in Scheme

Bill Schottstaedt — 2013-05-09T11:18:19

(Just as I was about to press "send", Rick's answer arrived,
but I'll send my redundant verbiage anyway).

In s7, define* arguments are optional and have keyword names
without any marker like &optkey (:optional is accepted, but ignored).
I'm not sure where &optkey comes from, perhaps def-optkey-fun
in the Common Lisp version of clm?

(define* (hiho a (b 0) (c 0)) (+ a b c))

has 3 optional/keyword arguments.

(hiho 1) -> 1
(hiho 1 11) -> 12
(hiho :c 0 :b 11 :a 1) -> 12

See s7.html under define* (the third major section of the doc).
s7.html has tons of examples, and there are many more in the
Snd *.scm files.  The s7 version of clm is primarily
documented in sndclm.html.

Re: optional arguments in Scheme

Heinrich Taube — 2013-05-09T11:07:08

hi  if you use s7's define then you don't need OptKey at all because all arguments will be opt key:

   (list a b c d e))

(#f #f #f #f #f)


(1 2 #f #f #f)

(1 2 3 4 5)

Hello,

I am having a hard time understanding optional arguments 
in Scheme and could use a little help.
I want to pass optional arguments, without having to write 
the keywords and it seems that in that 
case "&optkey" becomes an argument!...


(define* (hiho a &optkey (b 0) (c 0))
  (+ a b c))

(hiho 1 12)

=> 1

(hiho 1 12 1 1)

=> 3

Neither s7 documentation nor Common Music's reference 
or examples give an overview of the syntax 
for optionals and rests arguments. Could you be kind enough 
to point me the right direction? :)
Thank you!

Re: Installing snd and s7 on MacOS-X Mountain Lion

Bill Schottstaedt — 2013-05-05T11:42:49

I think the easiest way is to configure snd without any GUI:

./configure --with-no-gui
make

This will give you snd/clm/s7 in an old-style interpreter.
There are several suggestions in README.Snd -- perhaps
you can get motif or gtk from one of the packagers
mentioned there.  I don't recommend trying to build
either one yourself -- both are borderline impossible
to get going by hand.  I can't upgrade my old Mac to
the new OSX, so I haven't tested it.

Good luck!

Installing snd and s7 on MacOS-X Mountain Lion

Hi !
New to cmdist. Is there any easy way to install s7 scheme and snd on Mac-OSX Mountain Lion ?
Thanks a lot,

Re: S7 scheme running on Android in NDK

Bill Schottstaedt — 2013-05-03T23:39:06

Thanks very much!  I have merged those changes into the
ccrma and sourceforge copies of s7.  


That's the truth!  Sorry you got bitten.  As far as I know, that one
spot is the only unaligned access.  Please let me know of any other
troubles.

By the way, how do you run it in Android?  I had somehow convinced
myself that I needed Java.

S7 scheme running on Android in NDK

Jason Ripley — 2013-05-03T22:17:04

Hi,

I have just added s7 scheme to a C++ project on Android, and I ran into a
couple of issues that I would like to post in case anyone else runs into
them.

1 - android doesn't seem to support the log2 function.  Easy fix:  fx =
log((double)ix)/log(2.0);

2 - It seems that arm based architectures have issues with aligned access.
I discovered this when calling s7_init to create a second scheme vm.  The
fix for this is to simply add __ANDROID__ to the __bfin__ check.


here is the diff of the changes for s7.c:

4021c4021
< #if (__bfin__)
---
10216a10217,10219
10217a10221


Are there any other spots in s7 where unaligned access may occur?  They are
rather difficult to debug.


Sincerely,
Jason Ripley

Re: scheme, s7

Ralf Mattes — 2013-04-25T22:48:55

Sorry, I might not get what you are after. 

 (define counter 0)

Here, you create a binding (i.e. you create a  "variable"  and assign an initial value to it).

  (define (bump-counter)  
    (process repeat 5 do(set! counter (+ counter 1))))

Here you create a function that, when called, will return whatever 'process' return, which is
most likely not what you want (since process will return an anonymous function). I guess you want
'bump-counter' to actually modify your counter.

  (define (bump-counter)
    (loop repeat 5 do (set! counter (+ counter 1))))
 
Should do the job. But maybe I don't understand your question.

Re: scheme, s7

Bill Schottstaedt — 2013-04-25T20:47:13

I think in your example you need "sprout":

cm> (define counter 0)
counter
cm> (define (bump-counter) (process repeat 5 do (set! counter (+ counter 1))))
bump-counter
cm> (sprout (bump-counter))

cm> counter
5


In straight scheme there are several ways to do this:

(do ((i 0 (+ i 1))) ((= i 5)) (set! counter (+ counter 1)))

for example.

scheme, s7

James Hearon — 2013-04-25T20:03:27

Hi,
Having a devil of a time trying to figure out how to assign a variable and increment a counter in a loop or process.  Easy enough in c, but really struggling to do this in scheme.

(define counter 0)
(define (bump-counter)  (process repeat 5 do(set! counter (+ counter 1))))
(bump-counter)

Something like that would be what I'm after.  Tried using LET, also declaring LET or SET outside the process or a loop but still within the definition, and no joy there.
Any help for the parenthetically challenged greatly appreciated.

Snd 13.6

Bill Schottstaedt — 2013-04-22T15:28:39

Snd 13.6

added environment-ref|set!
      char-position and string-position (moved from Snd to s7)
      make-formant-bank and formant-bank? (and changed formant-bank again)
      comb-bank, all-pass-bank, and filtered-comb-bank generators
      one-pole-all-pass generator moved to C
      envelope-interp, rxyk!cos, and rxyk!sin moved to C
      yet another version of oscil-bank

removed mus-file-prescaler and mus-prescaler  -- these no longer serve any purpose.

checked: gtk 3.7.14, 3.8.0|1, sbcl 1.1.6.

Thanks!: Michael Edwards, Mike Scholz

Re: Grace,s7, system

Bill Schottstaedt — 2013-04-05T18:41:18

system returns an integer that in C can be decoded with the
macros in sys/waits.h, or something like that.  I think 65280
= #xff00 so that means the child process exited normally.
Just a quick guess after looking at /usr/include/bits/waitstatus.h.
Not sure this is helpful.

Grace,s7, system

James Hearon — 2013-04-05T16:30:24

Hi,
I'm wondering what "65280" means.

I'm trying to use the s7 "system" call from Grace,
ex.

(system "/home/Grace/test.sh")

It works fine on some things, such as if .sh contains:

#! /bin/sh
cd /opt/snd-13.5
./snd 808loop.wav

and returns 0, but on other items I just get "65280" returned in Grace.  I've checked file permissons, ownership, execution of .sh file etc.  Seems to have something to do with whether the program uses graphics or opens in a terminal.    The troublesome programs fire just fine if I directly run the .sh file from command line outside of Grace/s7.

Grace, cs:event

James Hearon — 2013-03-31T05:16:32

cs:event (list)
  
    
  
  → void




Sends an event list to Csound. The first element in the list must be the event's type, either i or f. Similar to "cs:i" and "cs:f" in all other respects. 


Hi,I hope I'm on the right list for this query. I have below using scheme, and so far so good...
(cs:i 1 0 1 440 1000)
(cs:f 1 0 1024 10 1)
but stuck here..(cs:event (list (cs:i 1 1 1 880 1000)))
I haven't been able to discover what the interpreter needs to stop bonking at me, although it does seem to write it to the console when using Audio>Csound>Export Score in spite of the error shown.
... Error: #<unspecified> is not a Csound statement type

If some kind soul has an example, I would appreciate seeing how it's done.

Regards,
