Emu

Emu is a simple systems language ala C. Emu is built from Haskell, C++, and LLVM.

How far along is Emu?

Emu is "complete" in the sense that I've implemented all the features I set out to implement when I started the project. If I feel like adding more (a good module system, comptime arguments, etc.), I will, but no promises.

• Basic CLI interface
• Parser & AST
• Semantic analysis
• Haskell to C++ marshalling
• LLVM code generation
• Fleshed out command line interface
• Comptime evaluator
• Full language semantic checking
• Core language feature-set
• Documentation

Installation

To build emu, you will need GHC, Cabal, g++, and LLVM installed. You should install g++ and LLVM through your system's package manager. To install GHC & Cabal, I recommend you use GHCup. To build the project, just run

cabal build

in the project root. The built executable will be at dist-newstyle/build/<OS>/<ghc-version>/<emu-version>/x/emu/build/emu/emu. To build the provided tests / examples, you will need GNU make. Navigate to the tests/c-tests directory and run

make all

There is an Emacs major mode in the emacs directory. To use it, add

(autoload 'emu-mode "emu-mode" nil t)

to your init.el file.

Documentation

There is a tutorial for writing Emu code at docs/tutorial.md.
