Mach7
A functional programming style pattern-matching library for C++ that provides user-definable patterns and open class hierarchies.
What is Mach7?
Mach7 is a pattern-matching library for C++ that brings functional programming abstractions to the language. It allows developers to write concise, expressive code for decomposing and matching against data structures, providing an alternative to verbose visitor patterns and switch statements. The library supports user-definable patterns that work with both built-in types and complex class hierarchies.
C++ developers working on compilers, interpreters, or code that requires complex data structure decomposition and matching. Particularly useful for those implementing domain-specific languages, symbolic computation, or algorithms that benefit from pattern-matching paradigms.
Mach7 offers a library-based approach to pattern matching that doesn't require language extensions, maintains C++ performance characteristics, and provides more expressive syntax than traditional alternatives like the Visitor pattern. It enables open class hierarchies and works with third-party types without modification.
