Hello,
I am using snd-ls 0.9.7.12. I have searched through documentation, and fail to
see how I can define the end point of a selection started with C-space. Am I
missing something? I would like to move the cursor into position, press
C-space, move the cursor to a new position, and press some key to have the
selection end there. I am expecting to see a high-lighted selection at the end
of that process.
How do I do this? It's such a simple thing, yet I can't find any info anywhere?
I don't know if theres anything built in, but its relatively easy to add a
keybinding to do it yourself.
To let C-space select both start and end of selection plus cancel it, put
the following lines into your .snd-ls file:
(bind-key (char->integer #\ ) 4
(let ((selstart #f))
(lambda ()
(let ((set-selstart! (lambda ()
(report-in-minibuffer (format #f "Selection start at ~A" (cursor)))
(set! selstart (cursor)))))
(if (c-selection?)
(begin
(set! (selection-member? #t) #f)
(set-selstart!))
(if selstart
(begin
(c-set-selection! (c-selected-sound) 0 (min selstart (cursor)) (max selstart
(cursor)))
(report-in-minibuffer "")
(set! selstart #f))
(set-selstart!)))))))
(load-from-path "snd_conffile.scm")
BTW, I am not an emacs user. Perhaps things would be
clearer to me if I was.
(I'd be terribly interested in a vim-like snd, BTW, if anyone knows anything).
I'm sure it would be possible to customize snd to become more like
vim.

Hmm. I definately wouldn't have come up with that. How do people normally
terminate a selection? Or is it just always done with the mouse? If so, why
have the default C-space binding at all?

Well. :-)
It was ment to be a complete well-working example. You could get away with
something like this:
(bind-key (char->integer #\n) 4
(lambda ()
(set! (selection-frames) (- (cursor) (selection-position))))))
but the first one is much better. And this one is even better:
(bind-key (char->integer #\ ) 4
(lambda ()
(let* ((snd (c-selected-sound))
(old-selstart (c-get snd 'c-space-selstart #f))
(new-selstart (cursor)))
(cond ((c-selection?)
(set! (selection-member? #t) #f))
(old-selstart
(c-set-selection! (c-selected-sound) 0 (min old-selstart new-selstart) (max
old-selstart new-selstart))
(set! new-selstart! #f)))
(report-in-minibuffer (if new-selstart
(format #f "Selection starts at ~A" new-selstart)
""))
(c-put snd 'c-space-selstart new-selstart)))))

Yeah, I just use the mouse. Its not very efficient, but I don't
terminate a selection very often. I'm going to add the above code
to snd-ls though.
If so, why
have the default C-space binding at all?
Don't know...
