Demangled

Demangled is a cross-language demangling library and command-line tool designed to translate mangled symbol names produced by compilers into human-readable identifiers. It focuses on languages including C++, Rust, Go, D, and Swift, and is intended for use in debugging, profiling, crash reporting, and log analysis.

Demangled adopts a modular architecture with a core demangling engine and language-specific resolvers. The core implements common mangling formats such as Itanium C++ ABI and MSVC, while specialized backends handle language-specific schemes. The design emphasizes correctness, performance, and extensibility, allowing new demangling grammars to be added without modifying existing code. It provides a simple API for embedding in applications and bindings for popular languages.

Clients can invoke the library directly from code or use the included command-line tool to demangle text streams, stack traces, or log files. It supports streaming input to handle large dumps efficiently, and it can be integrated with build pipelines and crash-report systems to symbolicate stack traces automatically.

Demangled is distributed under an open-source license and maintained by an international community of contributors. It accepts community contributions, issue reports, and feature requests through its public repository and issue tracker.

Demangling refers to the process of restoring source-level identifiers from mangled names; it is a common task in compiler tooling and debugging ecosystems.
