Delta Programming Language

Delta is a high-performance programming language designed to improve programmer productivity. The project is still in early stages of development: some planned features have not yet been implemented, existing ones are subject to change, and the documentation is scarce.

Learn more about the language at https://delta-lang.github.io.

Contributing

Contributions are welcome and encouraged. See the GitHub issues and the Trello board for the project backlog. To ask a question or open a discussion, create an issue or join the Delta Discord server.

Building from source

Compiling Delta requires a C++17 compiler, CMake, and LLVM/Clang 11.

• Unix / macOS

  Download and extract LLVM/Clang 11 pre-built binaries for your platform from https://releases.llvm.org/download.html. Then run the following commands:

  mkdir build
  cd build
  cmake .. -DCMAKE_PREFIX_PATH="/path/to/llvm"
  

• Windows with Visual Studio

  Download and extract LLVM/Clang 11 pre-built binaries from somewhere, such as https://ziglang.org/deps/llvm%2bclang%2blld-11.0.0-x86_64-windows-msvc-release-mt.tar.xz (consider sponsoring Zig). Then run the following commands:

  mkdir build
  cd build
  cmake .. -DCMAKE_PREFIX_PATH="C:\path\to\llvm" -DCMAKE_GENERATOR_PLATFORM=x64 -Thost=x64
  

To run the tests, install lit via pip, e.g.:

sudo python -m pip install lit

After this, the following commands can be invoked from the build directory:

• cmake --build . builds the project.
• cmake --build . --target check runs the test suite.

The C++ code style is enforced by ClangFormat and ClangTidy:

• Run the format CMake target to format the code.
• Run the lint CMake target to check if the code is formatted.
