CLI

The package ships a validate command that tests LCMA form-annotation labels against the current grammar:

# Validate a single expression
musicalform validate -e "bi"

# Validate a text file
musicalform validate -f my_label.txt

# Validate all expressions in a CSV (column: 'expression')
musicalform validate -c annotations.csv

# Extract and validate from a JSON timeline file
musicalform validate -j piece.json -o reports/

# Recursively process a directory of JSON files
musicalform validate -d data/ -o all_results.csv

# Verbose mode (show parse trees and skipped files)
musicalform validate -e "bi" -v
