Emu is a simple systems language ala C. Emu is built from Haskell, C++, and LLVM.
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
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.
There is a tutorial for writing Emu code at docs/tutorial.md.
