CppShift

This project provide a C++ scanner and a transpiler. The goal is not to use compiled C++ like cxx can do, but to convert c++ code into native Rust.

This conversion need to be use with simple extract of code with specific need. The goal is not to bind an entire C++ library, but convert only the code you need.

Lexer

The first component is a Lexer, which parses and validates C++20 lexical elements.

To parse a C++ source file and display the decomposed tokens, run the lexer example:

cargo run --example lexer -- <source_path>

AST

The AST (Abstract Syntax Tree) structures a source file into a hierarchical tree.

It uses the Lexer’s token stream to build a syntax tree representing the C++ source code.

The design of the AST objects is heavily inspired by the syn crate. To parse a C++ source file and inspect the AST decomposition, run the ast example:

cargo run --example ast -- <source_path>
