# C8110 Voice Activated Relay - Build Script
#
# Double-click this file in Finder to build the .eap install packages for
# both Axis architectures (armv7hf and aarch64). You can also run it from
# Terminal with `./build.command`.
#
# The AXIS C8110 Network Audio Bridge runs an NXP i.MX 6SoloX, so
# **armv7hf** is the build to install on a C8110. aarch64 is built too so
# the same package can go on a newer Axis audio device for testing.
#
# (Note that this is the reverse of the sibling C17 Timer project, whose
# C1710 is an i.MX 8M Mini and therefore wants the aarch64 build. Easy to
# grab the wrong file if you have both folders open.)
#
# Requires Docker Desktop, installed and running, with network access
# (it pulls the Axis ACAP Native SDK image the first time).
#
# What this does, in order:
#   1. Reads the current version number from app/manifest.json.
#   2. Moves any .eap files already sitting in this folder from a
#      previous build into older-versions/, so this folder only ever
#      shows the newest build at a glance, but nothing is ever lost -
#      the last known-working build is always still there if a new one
#      turns out to be broken.
#   3. Builds a Docker image for armv7hf and extracts the resulting .eap
#      into this folder.
#   4. Does the same for aarch64.
#   5. Cleans up the temporary Docker containers used for extraction.
#   6. Bumps the patch version number (the last digit) in
#      app/manifest.json by one, so the NEXT time this script runs it
#      automatically builds the next version - no need to edit the
#      version by hand before each build.

  # window". Closing it explicitly here works regardless of that
  # setting. Matched by tty (this window's specific pseudo-terminal
  # device, e.g. /dev/ttys003) rather than by window title, so this can
  # only ever close the one window actually running this script - never
  # some other Terminal window that happens to have a similar title.
  # The close command runs in a detached, briefly-delayed background
  # subshell rather than inline: Terminal won't close a window it still
  # considers "running a process," so this gives the script's own shell
  # a moment to fully exit first.
  # Guarded on the path actually looking like a terminal device: `tty`
  # prints "not a tty" when this is run from anything that isn't a Terminal
  # window, and handing that to osascript would LAUNCH Terminal.app purely
  # to ask it to close a window that was never open.
