mono/CppSharp

CppSharp is a tool and set of libraries which facilitates the usage of native C/C++ code with the .NET ecosystem.

It consumes C/C++ header and library files and generates the necessary glue code to surface the native API as a managed API. Such an API can be used to consume an existing native library in your managed code or add managed scripting support to a native codebase.

The supported target languages at present are C# and C++/CLI.

It can also be used as a library to parse native code into a syntax tree with a rich declaration and type information model.

Libraries

AST

Mirrors the Clang's C/C++ AST and type system classes in C# APIs.

Check out Clang's AST introduction docs for more details about its architecture.

• C++ declarations
• C++ statements / expressions
• C++ types
• Class object layout
• Declaration visitors
• Type visitors

Parser

Provides APIs for parsing of C/C++ source code into a syntax tree.

• Parsing of C/C++ source code
• Parsing of libraries archives symbols
• Parsing of shared libraries symbols
• Based on the very accurate Clang C++ parser.

Generator

Generates the glue binding code from a syntax tree of the native code.

• Multiple backends: C++/CLI and C# (P/Invoke)
• Multiple ABIs: Itanium, MS, ARM, iOS
• Multiple platforms: Windows, OS X and Linux
• Multiple runtimes: .NET and Mono
• C++ virtual methods overriding from managed code
• C++ multiple inheritance by translating to C# interfaces
• C++ std::string
• C++ default parameter values
• C/C++ semantic comments (Doxygen) to C# comments
• Extensible bindings semantics via user passes and type mapping
