It's an experimental compiler of EO to binaries.
To build it, install Rust and then:
$ cargo build --release
If everything goes well, an executable binary will be in target/release/fibonacci
:
$ target/release/fibonacci 7 40
This will calculate the 7th Fibonacci number 40 times. Don't try to play with much larger numbers, this binary code is very slow. It's just an experiment.
To compile your own program instead of this primitive recursive Fibonacci calculator, you have to
convert EO code into 𝜑-calculus terms and then
pass them to Emu
struct like this:
use eoc::emu::Emu;
pub fn main() {
let emu: Emu = "
ν0 ↦ ⟦ φ ↦ ν3 ⟧
ν1 ↦ ⟦ Δ ↦ 0x002A ⟧
ν2 ↦ ⟦ λ ↦ int-add, ρ ↦ ξ.𝛼0, 𝛼0 ↦ ξ.𝛼1 ⟧
ν3 ↦ ⟦ φ ↦ ν2(ξ), 𝛼0 ↦ ν1, 𝛼1 ↦ ν1 ⟧
ν5 ↦ ⟦ φ ↦ ν3(ξ) ⟧
".parse().unwrap();
print!("The result is: {}", emu.cycle());
}
This code is equivalent to the following EO code:
[] > foo
42 > x
x.add x > @
But in a more "functional" way:
[] > foo
42 > x
int-add > @
x
x
More tests are in src/emu.rs
file.
