Snd 15.5

Snd 15.5:

repl.scm to replace use of readline in various cases.  The main one is
  Snd without a GUI.  In this case, you need to tell Snd where to find
  repl.scm.  In my ~/.snd_s7 file, I have:

  (set! *load-path* (cons "/home/bil/cl" *load-path*))

  I think you can build this into Snd by using the SCRIPTS_DIR flag
  in the makefile.

checked: sbcl 1.2.9|10, gtk 3.15.10|11|12, 3.16.0

Snd: no tracking-cursor if one sound is stopped

I have another patch to fix a graphic problem when two or more sounds
are playing and with-tracking-cursor is not #f (or we start to play
the sounds with [Ctrl][Play]).

Example:

- (set! *with-tracking-cursor* #t)

- open and play two sounds

- stop one sound

  (the cursor of the other sound is motionless)

Snd: save-mix segfault

Hi, if a mix doesn't exist, Snd crashes after save-mix.

Example I

(define mix7 (integer->mix 7))
=> #<mix 7>

(mix? mix7)
=> #f

(save-mix mix7 "bye.snd")
-- segfault

Example II

- open-sound
- add a mix
- (define mix0 (caaar (mixes)))
- save-sound
- (save-mix mix0 "crash.snd")

The null pointer (returned by md_from_id) is in save_mix (snd-mix.c:3681),
called only by copy_mix and g_save_mix. copy_mix is safe because

  md = md_from_id(id);
  if (!md) return(-1);

save_mix returns a io_error_t and there is not a value suitable
for a mix, so the attached patch fixes the bug in g_save_mix.

[Snd] playback from marks

Hi,

 I just compiled latest snd-15 with motif and that seems to resolve
the issue. Sorry for the noise...

[Snd] playback from marks

Hi,

 I'm having the following problem trying to play a sound with mouse
interaction starting at a mark:

Hovering over the red triangle of the mark, the mouse cursor changes
into a right arrow. Clicking once locates the playback cursor to the
beginning of the sound (sample 0). Clicking a second time makes
the playpack cursor jump to the mark and start playback.

As the sound is rather long it's impossible to work like that if I
need to zoom in to a position where the beginning of the sound is not
visible.

Am I doing something wrong or is there a workaround?

The only customization from the standard I did is

(set! (with-tracking-cursor) #t)

I'm using snd 13.8

Any help appreciated!

Snd: region's peak_envs not updated after editing

Hello, you can see this bug with the follow steps:

  - make a region, no too short otherwise `peak_env_usable' returns
    "false" and the waveform is correct

  - edit the created region

  - from Regions view, move the slider to right. During the sliding,
    when `peak_env_usable' returns "true" in snd-chn.c:1797, it starts
    to display the old waveform.

The attached patch is a possible solution.

ccrma history

Andrew J Nelson's book about ccrma is available now:
"The Sound of Innovation: Stanford and the Computer
Music Revolution", about $30 at Amazon.  I certainly
enjoyed reading it, but I'm biased.  It's hard to believe
it was 46 years ago that I wandered into the Bay Area.

gtk mapped without transient parent

Hi,
On f21 I'm getting an error thru the Grace editor.    Wondering if anyone else has this problem and might know the problem?  I did grep a bit and GTK part seems throughout Sndlib in CM, but I can't be sure that's the issue.

Save File:
GtkDialog mapped without a transient parent...File not saved.

On f21 I have a gtk2 and dev files, and a gtk3 with dev files.  I tried rebuilding Grace, but the problem persists.

Regards,
Jim

Hi,
Thanks for the info.  I've built Snd-15.4 on f21, and not seeing anything about HAVE_COMPLEX_NUMBERS or HAVE_COMPLEX_TRIG from the build output.  Is that something I need to add when running make or gcc?
