Val is a research programming language to explore the concepts of mutable value semantics and generic programming for high-level systems programming.
This repository contains the sources of the reference implementation of Val. Please visit our website to get more information about the language itself.
The compiler is currently developed for Unix-like operating systems. Nonetheless, it should be compilable on Windows as well. Please, fill in an issue if you are experiencing problems on Windows.
This project is written in Swift and distributed in the form of a package, built with Swift Package Manager. You will need Swift 5.6 or higher to build the compiler from sources.
Our implementation depends on LLVM 11.0
Use your favorite package manager (e.g., port on macOS or apt on Ubuntu), make sure llvm-config is in your PATH, and create a pkgconfig file for your specific installation.
The maintainers of LLVMSwift were kind enough to provide a script:
swift package resolve
swift .build/checkouts/LLVMSwift/utils/make-pkgconfig.swiftNote: on Ubuntu, you will also need libc++ to link your code with LLVM:
apt-get install libc++-dev apt-get install libc++abi-dev
Once LLVM is installed and configured, you may compile Val's compiler with the following commands:
swift build -c releaseThat command will create an executable named valc in .build/release.
That's Val compiler!
We welcome contributions to Val. Please read through CONTRIBUTING.md for details on how to get started.
