Rune's C2Beef Binding Generator

a flexible C binding generator for the Beef Programming Language

Features

• macro constants
• using fields
• bitfields
• out parameters
• function pointers with parameter names

Library

For an Example, see this file that generates the clang bindings used by this library

using Rune.CBindingGenerator;

// allows you to customize the output
CBindings.LibraryInfo libraryInfo = scope .()
{
    args = char8*[?]("-Isome/dir"),
    customFunctionAttributes = "CallingConvention(.StdCall)",
    modifyEnumCaseSpelling = scope (spelling, parentSpelling, strBuffer) =>
    {
        // strBuffer can be used to change the character data of `spelling`
        // without overriding its contents
        //strBuffer = new .(spelling);
        strBuffer = null;

        if (spelling.StartsWith(parentSpelling))
            spelling.RemoveFromStart(parentSpelling.Length);
    },
    // ...
};

// set args that will be passed to clang
CBindings.args = char8*[?]("--language=c", "-I/some/path", "-DSOME_MACRO");

// generate a binding from a header
CBindings.Generate("/path/to/header.h", "Output.bf", "OutputNamespace", libraryInfo);
