Examples

Basic

cargo run -F wat -- compile test/add.ella -f wat with

_{test/add.ella}

export fn add(a: Int, b: Int): Int {
    let c: Int = a + b;
    return c;
}

as the input program currently yields following result:

(module
  (type (;0;) (func (param i32 i32) (result i32)))
  (func $add (;0;) (type 0) (param $a i32) (param $b i32) (result i32)
    (local $c i32) (local i32)
    local.get $a
    local.get $b
    i32.add
    local.set $c
    local.get $c
  )
  (export "add" (func $add))
)

Importing functions

_{test/import.ella}

from console import fn log(n: Int);

export fn hello(): Int {
    log(42);
    return 1;
}
