Class LabelEscaper

java.lang.Object

ca.mcscert.jpipe.util.LabelEscaper

public final class LabelEscaper
extends Object

Converts a human-readable jPipe element label into a valid Python identifier (snake_case).

The conversion is two-phase:

1. Unicode NFD normalisation followed by stripping of combining diacritics, so accented characters map to their ASCII base (e.g. é → e, ü → u).
2. Lowercasing, collapsing any run of non-alphanumeric characters to a single underscore, and stripping leading/trailing underscores. If the result starts with a digit an underscore prefix is added.

Examples:

• "The system is correct" → "the_system_is_correct"
• "Accuracy <= 0.85" → "accuracy_0_85"
• "café test" → "cafe_test"
• "100% accurate" → "_100_accurate"
