core.match is a high-performance pattern-matching library for Clojure and ClojureScript. It provides an optimized macro-based DSL for structurally matching data—such as sequences, maps, regexes—offering a clearer alternative to nested conditionals or destructuring. A symbol pattern can represent one of three behaviours. Match the value of an existing local binding. Create a "named" wildcard pattern that creates a binding of the given name to the right of the pattern row.

Features

  • match macro for structural pattern matching akin to ML/Haskell-style matching
  • Supports Clojure and ClojureScript seamlessly
  • Handles complex patterns: sequences, maps, predicates, regex-based patterns
  • Efficient under-the-hood algorithm for quick pattern dispatch
  • Avoids brittle conditionals by making patterns explicit and expressive
  • Compatibility with advanced usage contexts and custom pattern types
