Welcome to the open source EDG C/C++ compiler project!

The EDG C/C++ front end is the primary focus of this repository. The EDG front end is known for: its excellent parsing compatibility and bug emulation, to make sure source that compiles with Clang, GCC, and MSVC compiles with EDG; extensive documentation, to assist with development and modification; and extreme configurability, to allow it to be derived for use into a large number of C/C++ oriented products.

The compiler project also includes: a C-generating back end, which can be used to generate C code for C++ programs; a C++-generating back end, which is useful for source-to-source transformation applications; a prelinker, which handles automatic template instantiation; a minimal runtime support library (but not any "real" libraries, e.g., for stream I/O); utilities to write the intermediate language to a file, read it back in, and display it in human-readable form; a name demangler; and a collection of purpose built development tools.

See the documentation on: https://edgcpp.org/doc/. Documentation for the current development branch (main) is on: https://edgcpp.org/dev/doc/.

To get started, it's recommended for most people to clone the repository using a partial clone (this keeps a full copy of the git history while only downloading the most recent version of each file, git can implicitly fetch older versions as needed):

git clone --filter=blob:none git@github.com:edgcpp/compiler.git

If you are looking to build the front end from source and use it, please see the build instructions.

If you are looking to make changes to the front end, please see the contribution guide and the development guide for quickly getting setup.

To further aid humans and AI agents in product development there is additional documentation for tips, tricks, and tutorials that can be found in the development annex.
