ExForth

Forth-inspired stack language that compiles to Elixir

ExForth is a custom programming language inspired by Forth and Factor, implemented in Elixir. It combines the elegance of stack-based programming with modern functional concepts, compiling directly to efficient Elixir modules.

Features

• Stack-based execution - Classic Forth-style reverse Polish notation
• Compiles to Elixir - Transforms source code into efficient Elixir modules
• Native extensions - Define Elixir functions directly using ex:
• Pattern matching - Unique do-blocks inspired by Factor's combinators
• First-class quotations - Lambda expressions with [ ... ] syntax
• Control structures - IF/ELSE/THEN, BEGIN/UNTIL, DO/LOOP
• Variables - Global variables with @ (fetch) and ! (store)
• Local variables - Using { var1 var2 } syntax
• Modules - Import other source files with use
• Supervision - Built on Elixir's OTP for robustness

Installation

Add exforth to your dependencies in mix.exs:

def deps do
  [
    {:exforth, "~> 0.1.0"}  # or {:exforth, github: "ZeroMoonSan/ExForth"}
  ]
end

Quick Start

  def start(_type, _args) do
    children = [
      ExForth.Vars,
      ExForth.Cache,
      ExForth.FLoader,
    ]
# Load and compile a Forth file
iex(1)> ExForth/FLoader.load("path/to/your/file.fs")
{:ok, "ExForth.FLoader.Scripts.File"}
# Run the compiled module
iex(2)> ExForth.FLoader.Scripts.File.exec()
