#
# Run Bubble server or CLI commands. A wrapper for starting a JVM to run Bubble programs.
#
# Usage:    run.sh [debug [debug-port]] [command] [args]
#
# All arguments are optional:
#
#   debug       : if the first argument is the literal string 'debug' then immediately after starting,
#                   the Java process will wait for a debugger to attach. Default is not to enable debugging.
#   debug-port  : the port that will be listened on for the debugger. Default port is 5005
#   command     : the CLI command to run, or 'server' to run BUBBLE API server. Default is to run Bubble API server
#   args        : depends on the command. Use '-h' to request help for a command
#
# Environment variables
#
#   BUBBLE_ENV      : env file to load, used when performing handlebars substitutions on entities marked
#                        with `"_subst": true` JSON attribute. Default is ~/.bubble.env
#   BUBBLE_JVM_OPTS : Java options. Defaults to either "-Xmx512m -Xms512m" when no command is set, else "-Xmx64m -Xms2m"
#   BUBBLE_JAR      : location of bubble uberjar. Default is to assume there is exactly one bubble-server*.jar file in a
#                       directory named "target" that is in the same directory as this script
#
# Environment variables for API commands
#
#   BUBBLE_API      : which API to use. Default is local (http://127.0.0.1:PORT, where PORT is found in .bubble.env)
#   BUBBLE_USER     : account to use. Default is root
#   BUBBLE_PASS     : password for account. Default is root
