Tango Programming Language

Tango is a custom programming language with its own compiler and virtual machine, implemented in Go.

Overview

Tango is a simple language that supports:

• Variable declarations
• Arithmetic operations
• Boolean operations
• Print statements

Example

let a = 1;
let b = a + 2;
let c = (b - 5) * 3 / 4 + 2;
print c;

let x = true;
let y = !x;
print y;

Project Structure

• lexer/ - Tokenizes the source code
• parser/ - Parses tokens into an abstract syntax tree (AST)
• ast/ - Abstract syntax tree definitions
• compiler/ - Compiles AST into bytecode
• bytecode/ - Bytecode definitions and utilities
• vm/ - Virtual machine that executes bytecode
• token/ - Token type definitions
• repl/ - Read-Eval-Print Loop for interactive execution
• cmd/ - Command-line tools

Usage

Or using npm scripts:

npm run run

Compiling a Program

go run cmd/tango/main.go compile test.tango

Or using npm scripts:

npm run gen:bytecode

Building the Executable
