editDistance(String a, String b) → int

Levenshtein (edit) distance between a and b.

findClosestTargetId(String typo, Set<String> known, {int maxDistance = 2}) → String?

Closest candidate for typo among known, or null if none are close.

formatHintSkipped(String tourId, int stepIndex, String targetId, HintSkipReason reason, String detail) → String

A single diagnostics line fit for logging.
