# Cpp2Beef
Cpp2Beef is a library for writing high quality beef bindings for C and C-Style C++. Cpp2Beef does the heavy lifting so you can focus on the library specific stuff.

You can find bindings generated by Cpp2Beef at https://git.unicon-gmbh.de/BeefBindings.

## Usage
1. Create a `Setup` workspace and add Cpp2Beef from remote (`https://git.unicon-gmbh.de/Rune/Cpp2Beef.git`)
2. Add Cpp2Beef as a dependency
3. Write your generator
```beef
class ExampleGenerator : Cpp2BeefGenerator, this(Span<char8*> args)
{
	protected override Span<char8*> Args => args;
	protected override Flags Flags => .None;

	// You can have your binding in one file or in multiple, file management is up to you
	StreamWriter writer = new .()..Create("../src/Example.bf")..Write("""
		// This file was generated by Cpp2Beef

		using System;
		using System.Interop;

		namespace Example;


		""") ~ delete _;

	protected override StreamWriter GetWriterForHeader(StringView header)
	{
        // Here you define the target file to which a cursor should be written
        // Returning null skips the cursor
		if (header.EndsWith("example.h"))
			return writer;
		return null;
	}

	protected override Block GetCursorBlock(CXCursor cursor)
	{
        // Optional. This can be used put cursors in custom blocks
        // This is useful if you want all your functions to be a static class
		if (cursor.kind == .FunctionDecl)
			return .CustomBlock("Example");
		return base.GetCursorBlock(cursor);
	}

	protected override void HandleCursor(CXCursor cursor)
	{
		// Optional. Can be used to write custom logic, how a cursor should be written
		// If your going for this I'd recommend looking at examples in BeefBindings
		base.HandleCursor(cursor);
	}

	protected override void WriteCustomAttributes(CXCursor cursor)
	{
		// Optional.
		base.WriteCustomAttributes(cursor);
	}

	protected override void GetNameInBindings(LibClang.CXCursor cursor, String outString)
	{
		// Optional but you pretty much want to always override this.
		// Allows you to change the name of cursors
        base.GetNameInBindings(cursor, outString);
	}
	
	// There are functions you can override, but these are the most common
}
```
