Ferret Programming Language

Explicit ownership, practical semantics, and a compiler-first workflow.

Get Started Source Code

Features

Ownership & Safety

Ferret uses explicit pointer ownership and compile-time analysis to make memory behavior visible and predictable.

Practical Type System

Built-in optionals ?T, error unions E!T, enums, structs, and interfaces keep APIs explicit.

Large Number support

We are not limited to 64 bit numbers. You can go as far as you want

Quick Look

type Mode enum {
  debug,
  run,
}

fn SelectMode(v: i32) -> Mode {
  if v > 0 {
    return Mode::run
  }
  return Mode::debug
}

fn main() {
  let mode = SelectMode(1)
  if mode == Mode::run {
    println("Ferret is running")
  }
}
