[CM] Getting snd to work with conjure/neovim

[Kenneth Flak]

Had a bit of time to dig further into the whole nvim/conjure/snd thing, and I might be making some headway here.

Would it be reasonable to assume that snd executes commands from stdin as one-shot events? I do get a return value back to the repo on exit from snd, but not immediately after executing a command.

Test code:

(begin
   (open-sound "/home/kf/xylophone.wav")
   (scale-channel 0.1)
   (save-sound-as "/home/kf/xylophone-scaled-1.wav")
   (exit)
   )

This produces this log in conjure:

; --------------------------------------------------------------------------------
; snd (started)
; --------------------------------------------------------------------------------
; eval (root-form): (begin (open-sound "/home/kf/xylophone.wav"...
; debug: send
"(begin
   (open-sound \"/home/kf/xylophone.wav\")
   (scale-channel 0.1)
   (save-sound-as \"/home/kf/xylophone-scaled-1.wav\")
   (exit)
   )
"
; debug: receive
"err"
; debug: receive
"out"
; process exited with code 1
; --------------------------------------------------------------------------------
; snd (stopped)

If I omit the (exit) in the code, the processing happens, but snd blocks any further input until it exits (manually or programmatically).

Best,
Kenneth
