Lodestar.Fuzzy

Applied fuzzy string matching with rapidfuzz's semantics: Fuzz.Ratio, PartialRatio, TokenSortRatio, TokenSetRatio and WRatio; Process.Extract and ExtractOne over a list of choices; and blocking deduplication for a list too long to compare pair by pair. The scores are the ones rapidfuzz returns, on a 0 to 100 scale.

Install

dotnet add package Lodestar.Fuzzy

Example

using Lodestar.Fuzzy;

string[] choices = ["apple pie", "apple tart", "banana bread", "cherry pie"];

IReadOnlyList<ExtractResult> best = Process.Extract("apple pie", choices, limit: 2);
string first = best[0].Choice;                    // apple pie
double typo = Fuzz.Ratio("apple pie", "appel pie"); // 88.88888888888889

Parity

Replayed against rapidfuzz's fuzz and process modules. docs/equivalence.md maps each Python call to its C# counterpart, with every deliberate divergence.
