toy-lang-fun 0.1.2

A toy functional programming language

Toy Language Interpreter

A minimalist Scheme-like programming language interpreter written in Python. This project implements a custom programming language with support for basic arithmetic operations, conditionals, and functional programming concepts.

Features

• Lambda functions and closures
• Basic arithmetic operations (+, -, *, /)
• Comparison operators (<, >, <=, >=)
• Boolean operations (and, or, not)
• Conditional statements (if)
• Local variable bindings
• Comments support

Installation

# Using pip
pip install toy_lang

Quick start

; Hello World
(display "Hello, World!")

; Basic arithmetic
(+ 1 2 3)  ; => 6
(* 4 5)    ; => 20

; Lambda functions
(lambda (x) (* x x))

; Conditional statements
(if (> 5 3)
    "yes"
    "no")

Language Features

Arithmetic Operations

• Addition: (+ 1 2 3)
• Subtraction: (- 10 5)
• Multiplication: (* 2 3 4)
• Division: (/ 10 2)

Comparison Operators

• Less than: (< 5 10)
• Greater than: (> 10 5)
• Less than or equal: (<= 5 5)
• Greater than or equal: (>= 10 10)

Boolean Operations

• And: (and #t #f)
• Or: (or #t #f)
• Not: (not #t)

Functions

; Define a function
(lambda (x) (* x x))

; Using begin for multiple expressions
(begin
  (define square (lambda (x) (* x x)))
  (square 5))
