def Lean.FuzzyMatching.fuzzyMatchScore? (pattern : String) (word : String) : Option Float

Match the given pattern with the given word using a fuzzy matching algorithm. The resulting scores are in the interval [0, 1] or none if no match was found.

def Lean.FuzzyMatching.fuzzyMatchScoreWithThreshold? (pattern : String) (word : String) (threshold : optParam Float 0.1) : Option Float

Equations

• Lean.FuzzyMatching.fuzzyMatchScoreWithThreshold? pattern word threshold = Option.filter (fun (x : Float) => decide (x > threshold)) (Lean.FuzzyMatching.fuzzyMatchScore? pattern word)

def Lean.FuzzyMatching.fuzzyMatch (pattern : String) (word : String) (threshold : optParam Float 0.2) : Bool

Match the given pattern with the given word using a fuzzy matching algorithm. Return false if no match was found or the found match received a score below the given threshold.

Equations

• Lean.FuzzyMatching.fuzzyMatch pattern word threshold = (Lean.FuzzyMatching.fuzzyMatchScoreWithThreshold? pattern word threshold).isSome
