Why Raven

• Compiled to native machine code through Cranelift, into a single static binary.
• Static typing with generics, traits, and sum types checked by an exhaustive match.
• A tracing garbage collector and Result/Option instead of null.
• Goroutines and channels for concurrency, and a C FFI for native libraries.
• A package manager (rvpm), one canonical formatter, and a VS Code extension.

Quick Example

struct User {
    name: String,
    age: Int,
}

fun greet(user: User) -> String {
    return "Hello ${user.name}, you are ${user.age}"
}

fun main() {
    let u = User { name: "Raven", age: 2 }
    print(greet(u))
}

Install

Download the installer or archive for your platform from the releases page:

• Linux: .deb, .rpm, or .tar.gz
• Windows: .msi or .zip

This installs the raven compiler and the rvpm package manager and adds them to your PATH. Compiling a program also needs a C linker on your machine (the MSVC build tools on Windows, cc/clang on Linux).

Quick Start

# Compile a source file to a native binary
raven build hello.rv -o hello
./hello

Project workflow with rvpm:

rvpm init my_app
cd my_app
rvpm run          # builds and runs src/main.rv
rvpm fmt          # format the .rv sources

Build from source

For contributors, or to track the latest commit:

git clone https://github.com/martian56/raven.git
cd raven
cargo build --release

The raven and rvpm binaries land in target/release/.
