# Description: script to automate PlatformIO builds
# CLI:  python auto_build.py build_option
#    build_option (required)
#        build      executes ->  platformio run -e  target_env
#        clean      executes ->  platformio run --target clean -e  target_env
#        upload     executes ->  platformio run --target upload -e  target_env
#        traceback  executes ->  platformio run --target upload -e  target_env
#        program    executes ->  platformio run --target program -e  target_env
#        test       executes ->  platformio test upload -e  target_env
#        remote     executes ->  platformio remote run --target upload -e  target_env
#        debug      executes ->  platformio debug -e  target_env
#
# 'traceback' just uses the debug variant of the target environment if one exists

#
# General program flow
#
#  1. Scans Configuration.h for the motherboard name and Marlin version.
#  2. Scans pins.h for the motherboard.
#       returns the CPU(s) and platformio environment(s) used by the motherboard
#  3. If further info is needed then a popup gets it from the user.
#  4. The OUTPUT_WINDOW class creates a window to display the output of the PlatformIO program.
#  5. A thread is created by the OUTPUT_WINDOW class in order to execute the RUN_PIO function.
#  6. The RUN_PIO function uses a subprocess to run the CLI version of PlatformIO.
#  7. The "iter(pio_subprocess.stdout.readline, '')" function is used to stream the output of
#     PlatformIO back to the RUN_PIO function.
#  8. Each line returned from PlatformIO is formatted to match the color coding seen in the
#     PlatformIO GUI.
#  9. If there is a color change within a line then the line is broken at each color change
#     and sent separately.
# 10. Each formatted segment (could be a full line or a split line) is put into the queue
#     IO_queue as it arrives from the platformio subprocess.
# 11. The OUTPUT_WINDOW class periodically samples IO_queue.  If data is available then it
#     is written to the window.
# 12. The window stays open until the user closes it.
# 13. The OUTPUT_WINDOW class continues to execute as long as the window is open.  This allows
#     copying, saving, scrolling of the window.  A right click popup is available.
