What is KORE?
KORE is a self-hosting programming language that combines the best ideas from multiple paradigms:
| Paradigm | Inspiration | KORE Implementation |
|---|---|---|
| Safety | Rust | Ownership, borrowing, no null, no data races |
| Syntax | Python | Significant whitespace, minimal ceremony |
| Metaprogramming | Lisp | Code as data, hygienic macros, DSL-friendly |
| Compile-Time | Zig | comptime execution, no separate macro language |
| Effects | Koka/Eff | Side effects tracked in the type system |
| Concurrency | Erlang | Actor model with message passing |
| UI/Components | React/JSX | Native JSX syntax, components, hot reloading |
| Targets | Universal | WASM, LLVM native, SPIR-V shaders, Rust transpilation |
Example
// Define a function with effect tracking
fn factorial(n: Int) -> Int with Pure:
match n:
0 => 1
_ => n * factorial(n - 1)
// Actors for concurrency
actor Counter:
var count: Int = 0
on Increment(n: Int):
count = count + n
on GetCount -> Int:
return count
fn main():
let result = factorial(5)
println("5! = " + str(result))
