Groovygo

A minimal Groovy-like scripting language implemented in Go. It features dynamic typing, functions, maps, arrays, dot-call access, and a simple REPL.

---

🚀 Features

• Dynamic types: number, string, bool, nil, arrays, maps
• First-class functions with closures
• Dot-style property access (e.g., obj.key)
• Simple built-in functions (println, len)
• REPL + script file execution
• Easy to extend (lexer, parser, AST, evaluator)

---

📦 Installation

Clone the repository:

git clone https://github.com/yourname/groovygo.git
cd groovygo

Build:

go build

Run REPL:

./groovygo

Run a script:

./groovygo example.groovygo

📜 Example Script (example.groovygo)

println("Hello from groovygo!")

x = 10
y = 32
println("x + y = " + (x + y))

nums = [1, 2, 3]
nums.append(4)
println(nums)

person = {
  name: "Alice",
  age: 30
}
println(person.name)

square = fn(n) {
  return n * n
}
println(square(5))

🛠 Project Structure

/lexer        – token definitions + lexical scanner
/parser       – Pratt parser + AST
/object       – runtime object system
/evaluator    – evaluator for AST nodes
main.go       – REPL and script runner

🔧 Extending the Language

You can easily add:

• Classes / prototypes
• Modules
• Standard library functions
• Bytecode + VM backend
