annotate osc/sv-command @ 182:21a76c9ed5c3

* Merge transform directory from sv-match-alignment branch
  (the previous comment included notes for this stuff, but I missed it
  in the actual merge)
* Fix crash when a transform fails to create an output model and the
  thread that created the transform then deletes its input model thinking
  it's no longer needed, even though the transform run thread is still
  using it -- fix is to wait() on the transform before returning the
  null output model

#!/bin/sh
#
# A very simple command shell for Sonic Visualiser.
# 
# This provides a wrapper for the sv-osc-send program, which is a
# generic OSC sending program (not specific to SV, despite its name).
# This script attempts to guess the OSC port number for an SV
# process running on the local host, and then composes a method name
# and arguments into a complete OSC call.
# 
# You can either run this with the method and its arguments on the
# command line, e.g. "sv-command set layer Frequency-Scale Log", or
# you can provide a series of method + argument commands on stdin.
# 
# Unless you use the -q option, this script will echo the OSC URL
# and arguments that it is sending for each command.
#
# Note that the method and arguments may not contain spaces.
