#!/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.
