thanks. cool to see an ftp server still in action these days.

snd is also available via https: 
<https://ccrma.stanford.edu/software/snd/snd-24.5.tar.gz>

however: the website itself (<https://ccrma.stanford.edu/software/snd/>) 
still lists the old 24.4 release.

For the Debian packaging of 'snd', I heavily rely on a public website 
that lists the current release. automation tools build on that.

it would be cool if the homepage could be updated.

Hi Bill and other s7 folks. I'm curious what the smartest way to make
execution stop in the middle of some code is, for the purpose of having an
interactive debugger. ideally with as little change to containing code as
possible. Perhaps this exists already in the s7 sources and I just haven't
found it!

thanks

s7.html has a section toward the end of the file about
repl.scm and nrepl.acm.  These have a function drop-into-repl
which can be used to poke around in the current context.
I think you could call this when an error is hit, or
if you're in a "raw" terminal, when you hit some key
like C-C.  The file debug.scm has (very lightly tested)
functions for break points and the like-- it also could drop into
a repl.  I have wanted for a long time to tie the object->let
code in s7 into a debugger, so you could examine structures
and so on.  s7 badly needs a decent debugger.

SDL is a means to an end not the goal so I wrote the wrapper to
support the small sliver of SDL that I need and left it alone
(progress since my last email: zero). In fact I originally obtained
an OpenGL context using xlib directly but for this project I thought
the portability would be nice despite the extra baggage so SDL was
sort of wedged in at the last minute.

I was hoping to get the code it's part of into a clean and practical
state to show off the use of s7sdl but of course that just slips
back ever further, so I've extracted the relevant parts from that
into their own demo:

        git clone http://zeus.jtan.com/~chohag/balls.git

There's a lot in there that's not particularly relevant (not to
mention incomplete) because I didn't plan on making something new
for this demo: I've only stripped out some parts that were wholly
unnecessary such as fonts and tidied up a bit. The main addition
to the SDL wrapper itself is the draw tree implementation split
between balls.w and draw.w and of course the event handler.

Subject: [CM] Setting up snd/emacs
Message-ID: <87cyns6vd2.fsf@protonmail.com>


Hi,

I'm somewhat belatedly starting to realize the absolute 
awesomeness of emacs, and I'm now trying to get snd working with 
it... However, my initial attempts aren't workind very well..

This is what I have in my init.el right now, and I was hoping that 
it would do something magical whenever I open a .csm file (as 
suggested in the docs)

(load-file "~/dots/emacs/inf-snd.el")
(set-default 'auto-mode-alist
	     (append '(("\\.rbs$" . snd-ruby-mode)
                    ("\\.cms$" . snd-scheme-mode))
		     auto-mode-alist))
(autoload 'run-snd-scheme    "inf-snd" "Start inferior Snd-Scheme 
process" t)
(setq inf-snd-scheme-program-name "snd -separate")

No magic is happening, unfortunately. I am left hanging in 
Fundamental mode and that's about it... The snd-*-commands show up 
in M-x, but they don't really do very much.

I'm running emacs 29.4, arch linux and the latest version of 
sndwarp

Grateful for any help!

Best,
Kenneth

Subject: [CM] SDL is unchanged still but here's another for ImGui
Message-ID: <202407071932.467JWeXU425428@zeus.jtan.com>

Continuing from my SDL wrapper I have an S7 interface to ImGui. As
with SDL it's just been started and I've only got as far as I need
to make sure the libraries initialise and talk to each other.

On the other hand in both cases what's left is mostly writing the
S7 interface functions which for the most part should require only
naming the constant or function. Anyone like writing long lists of
repetetive code?

Unfortunately due to the way I've put together the project these
libraries are for, I've had to abandon s7imgui.scm and write it in
C directly but converting it back to a scheme module is straightforward
and (I've tested this) the ImGui .o files can be linked into a
loadable .so by cload.scm.

I'm copying the ImGui mailing list in to this email (if they've got
one, the project looks very modern) so they're aware that there's
another language interface in the works; any comments or suggestions
there are very welcome.

The demo can (still) be cloned from http://zeus.jtan.com/~chohag/balls.git

The interesting files for ImGui are:

cimgui.cpp & cimgui.h - C interface to ImGui

s7imgui.w - S7 wrapper around cimgui

glimgui.wpp - renderer, the "backend" in ImGui terms

And of course (build-ui) and the surrounding code from balls.scm.

The backend in glimgui.wpp expects to be used with the threaded
OpenGL draw tree that builds on s7sdl.scm (the undocumented draw.w)
but only *uses* the wrapper in s7imgui.w, it's not an essential
part of it.

Finally if anyone is interested I have ~750 lines of nuklear.scm
which I got to as far as displaying a window before I decided to
use ImGui instead. I'll not be using it again so if anyone wants
to finish an S7 wrapper around nuklear then let me know before it
ends up getting lost in the bowels of my $HOME.

Matthew

... Too modern for a mailing list, there is at least a contact address.

Writing no; generating... sometimes.

Faced with a similar problem, I've used s7 to generate C before.  Specifically, I can point towards util-extra.c.in at [1], which includes #(...) forms within the source, which expand to C, using a very simple function in scheme-macro-filter.scm there.

I take the opportunity to mention this, partly to join in very late on a snd/s7 list thread of a month or so ago, expressing communal enthusiasm for s7 (thread 's7 got some love in the Lisp game jam').  The program I'm pointing to does a lot of its work in s7, although (in the terms of the blogpost which started that thread) I can't tell if it uses the 'icing' or 'cake' model: C calls s7 main calls C calls s7.  The point of this paragraph is to log that I've become more and more of an s7 fan, in the sense that it seems to have exactly the right tone to match the extension problem very well.  So thanks, Bill.

Best wishes,

Norman

Indeed consider that tongue in cheek. I expect (hope!) by the end
there'll be a higher ratio of generated:written code. At this early
stage I'm more concerned with feeling out how the API will be
exported and a little bit of repetition isn't a huge problem yet.

There's also still a few features of S7 I'm not taking advantage
of yet like function signatures and I wouldn't like to have to
inject them into tangled up macros.

Thanks I'll take a look. I tend to lean toward CPP macros through
familiarity but that may change as I build up a body of code, provided
I can keep magic out of the build process.

This is essentially why I've settled on S7. There's no "FFI" as
such, instead I can flit back and forth between S7 and C seamlessly
as needed. I guess that makes S7 the ... fork?

I'm fully sympathetic with the less-magic point of view.  I've written a 
modest amount of CPP macro cleverness over the years, and I find my 
tolerance for CPP magic has gone _down_ rather than up over the 
years.[*]

As it happens, my previous version of that scheme-macro-filter.scm 
program was also written in the service of creating an FFI for a 
library.  That is, exactly the problem of writing repetitive code which 
I might want to change my mind about.   I started off writing a pile of 
CPP macros, and quickly confused myself.  I had at the time recently 
stumbled across s7, thought hmm...., and very quickly knocked together 
the core of the macro-filter program.

Have fun!

Norman



[*] At one point, a while ago, I participated in the maintenance of a 
library which was written in object-oriented C.  This being the 90s, and 
C++ still rather unstable, the original author of the library had 
elected to implement the OO system entirely in CPP macros.  This was 
simultaneously extremely impressive, and completely paralysing, since it 
meant that almost the only changes I was confident making were 
cut-and-paste-and-tweak.  I've had Views about the desirable features of 
a macro system ever since.

I think we forget how powerful our tools are sometimes.

Consider the lists of constants in s7sdl.scm. Each group has a shell
command that will extract the list from the SDL headers in the event
that it changes but in fact these were worked out after I'd copied
the lists into my editor with a simple mouse motion (it fits on a
screen!) and sorted and formatted them with a few keystrokes. That
would not have been fun 25 years ago.

Similarly with a few simple commands I can turn a list of symbols
into a sequence of instructions and all their metadata quicker than
I can work out how to write a macro to get the compiler to do it.

Sometimes I feel a bit dirty but I'm usually three or four tasks ahead already.

Wild times. But on the other hand at least we had very little JavaScript.

However on the gripping hand there was perl.

You need to install libmotif-dev package.
Use --with-motif.

since you are on a Debian-derivative, the easiest way to install all the 
dependencies needed (to build the Debian package 'snd'), is to

1. enable source repositories (e.g. 
<https://askubuntu.com/questions/158871/>)

2. install the dependencies:
```
sudo apt-get build-dep snd
```

this will *probably* give you more than you asked for (but then you 
could play around with other build-options as well...)

Looks like Ubuntu is using an older version of snd with the optional GTK3 GUI.
That option was removed in recent versions of snd. Current version uses Motif.

Installed the libmotif-dev package. Get a new make error as below.

Perhaps this is X libs missing. Perhaps I should apt-get build-dep snd

README.Snd has a list of the packages you need when you
use the --with-motif switch.  I haven't checked it since
about version 22.04 of Ubuntu.  You'll need xpm and maybe
xt, and probably one header file, shape.h from libext.
Also the x11-fonts-misc package.

If you do that you'll end up with all the GTK3 development stuff, which
is huge and not required here. 

As Bil pointed out you'll need libxpm-dev and libxt-dev, maybe some others
(check the docs).

Thank you. Those two 2 libraries were needed. Pops up with the GUI now. 
$ ./configure --with-gui --with-pulseaudio --with-gl

The high-lighted text in the pull-down options is a little hard to read, 
is my only grumble. Am up and running so I'll work through Getting Started.

Hi guys,

What is the appropriate way to apply this transformation to every

(let ((stretch 8)
      (file "/home/kf/Documents/REAPER Media/keen/keen-002.wav"))
  (with-sound (:output "/home/kf/mySamples/keen/keen-002.wav"

              (open-sound file)
              (sndwarp

                (* stretch (/ (framples) (srate))) ; duration

OK, making some progress here... This cycles through files, but I 
only get silence in the resulting files. I also get these errors:

>;
with-sound mus-error: ("can't open /home/kf/snd/keen-007.wav: No 
such file or directory")

with-sound mus-error: ("can't open /home/kf/snd/keen-017.wav: No

such file or directory")
>;
with-sound mus-error: ("can't open /home/kf/snd/keen-009.wav: No 
such file or directory")

which is weird, as I haven't specified that directory...?

Anyway, the current code is:

(let ((stretch 8)
      (indir "/home/kf/Documents/REAPER Media/keen/")
      (outdir "/home/kf/mySamples/keen/"))
  (for-each-sound-file
   (lambda (file)
     (with-sound (:output (string-append outdir file) :scaled-to 
     (db->linear 0))
                 (open-sound (string-append indir file))
                 (sndwarp 
                  0 ; beginning
                  (* stretch (/ (framples) (srate))) ; duration
                  file
                  :stretch stretch
                  :randw 0.2
                  :rev 0.01
                  :overlaps 40

Grateful for any help!

I think you don't need the open-sound, but the
file passed to sndwarp should be (string-append
indir file), not just file (the latter defaults
to the current directory).

Hi Bill,

Tanks for the tip. I tried to omit (open-sound), but this give me 
an error:

#<unspecified>
>framples: no such sound: #<undefined>
"*stdout*"[5]: (sndwarp 0 (* stretch (/ (framples) (srate))) file 
:stretch stretch :randw 0.2 :rev 0.01 :overlaps 40)

Reducing the example to a single file, this is the code:

(let ((stretch 8)
      (file "/home/kf/Documents/REAPER Media/keen/keen-005.wav"))
  (with-sound (:output "/home/kf/mySamples/keen/keen-005.wav" 
  :scaled-to (db->linear 0))
              ;; (open-sound file) ; if I enable this, everything 
              works as it should
              (sndwarp 
                0 ; beginning
                (* stretch (/ (framples) (srate))) ; duration
                file
                :stretch stretch
                ;; :srate 0.5 ; pitch shift. 1.0 unchanged, 0.5 1 
                octave down.
                :randw 0.2
                :rev 0.01
                :overlaps 40
                )
              ))

framples and srate refer to the currently opened sound if
none is passed as an argument, so the open-sound merely
provides a fallback, but leaves the file open, and has no
effect on sndwarp, unless I'm misreading that code.
The file argument to sndwarp worked in the single-file
case because you gave the full file-name.  I think
for-each-sound-file passes you the file-names
without any directory info.

(let ((stretch 8)
       (indir "/home/kf/Documents/REAPER Media/keen/")
       (outdir "/home/kf/mySamples/keen/"))
   (for-each-sound-file

            :rev 0.01

Message-ID: <CAN9NcLxzZj5EG8rgEszRDPgkPUDzCKQVAwm5v9Jar2NL+vv95g@mail.gmail.com>

Hi colleagues, I'm excited to announce that yesterday, on the very last day
of my forties (ha), I launched my s7-powered online music ed project.

The elevator pitch is essentially: online ear and harmony training tools
that don't suck - that are actually effective, efficient, and can be
customized for the serious student.

The engine is entirely in s7 running in WASM, communicating with a minimal
UI/IO layer in JavaScript and using a scheduler running in C++ in a WASM
audio worklet. The apps aren't winning any beauty contests, but they work
really well and do things I've never seen anywhere else,  and being able to
build it in Scheme has been fantastic. They work in Chrome, FF, and Edge. I
plan to create videos/blogs about how I got my scheme code playing well
with JS (and improving it further) and create better example code.

If you're interested in looking at it, the demos and videos are the best
place to start.
http://seriousmusictraining.com

Massive thanks to Bill and everyone who has contributed to s7 and helped me
out on the list on my path to lisp-infection! :-)
