############
# Simple script for preparing and deploying an alwaysAI app to Balena
# app_name arg should match the name of the application created in Balena
# To make this script runnable: run `chmod +x _name_of_this_script_.sh` in your command line
# NOTE: The entire app should exist in it's own repo.

# Extract app name from arg if present
if [ $# -eq 1 ]; then
    app_name="$1"
else
    # If not - run interactive prompt to get it
    echo 'Balena app name: '
    read app_name

# If no app name available - halt script as push will eventually fail without it
if [ -z $app_name ]; then
    echo 'No Balena app name argument provided'
    exit 1

# Download models from alwaysAI
# NOTE for LINUX users: ALWAYSAI_HOME will need to be set prior to this
if ALWAYSAI_HOME=$(pwd) aai app install; then
