# AnyRailExportAdditions.py - SteveT - 05/15/2025
# Intended to be run ONCE after opening a file generated by the AnyRail export
# The AnyRail export outputs a background .jpg, and a set of internal Block objects
# for all AnyRail "Sections" which have been assigned a "Name".
# This script does some cleanup of the generated Block and Turnout definitions, creates Sensors
# and assigns them to the corresponding Blocks
# Both Sensors and Turnouts are created to match your default hardware Connection.
# Requirements:
#   AnyRail "Section" names must contain a unique Block number, this number is used to generate 
#     the JMRI Block and Sensor systemNames.
#   AnyRail Turnouts must have "Label" names entered with a unique Turnout number or numbers.
#   If desired, you can include a unique "User Name" after the unique number, such as "186 Yard Track 1"
#     The number will be used for the SystemName, and the trailing text for the UserName
#   Be sure to check the JMRI System Console for any WARN or ERROR messages after running this script.
# Pre-export suggestions: set AnyRail Zoom to 1:6, disable "Show Visible track"
#
# Next steps: Run CreateSectionsFromBlocks.py and AddOccupancyIconsToPanel.py
#  
# Thanks to Cliff Anderson's AnyRailBuildSensorList.py and Bill Fitch's CreateSignalLogicAndSections.py
#   for some of the code and much of the inspiration
# TODO: handle underscore in AR SectionName
# TODO: "rename" the Block systemName to match (Block "move" currently causes NPE in JMRI)
