Ditto

The Universal Translator & Package Manager

A single, portable ~10MB binary that runs code from any language AND manages packages from any registry without requiring users to install runtimes.

The Magic

Zero-Config Polyglot Execution

✅ No Python installation needed
✅ No Node.js installation needed
✅ No Ruby installation needed
✅ No Go toolchain needed
✅ No Rust compiler needed
✅ No external dependencies
✅ Built-in offline package manager
✅ UNIVERSAL package manager (PyPI, npm, RubyGems, crates.io, Go)
✅ WASM runtime support (downloadable)

Just Ditto — a single binary with embedded interpreters AND package managers.

Quick Start

Run Code Directly

# Smart detection - just run it
Ditto run script.py           # Auto-detects Python
Ditto run app.js              # Auto-detects JavaScript
Ditto run program.lua         # Auto-detects Lua
Ditto run query.sql           # Auto-detects SQL
Ditto run main.c              # Auto-detects C

Install Packages (Universal)

# Search for embedded packages
Ditto search requests
Ditto search lodash --lang js
Ditto search rails --lang ruby   # NEW: Ruby support

# Manual
go build -o Ditto.exe ./cmd/ditto

Examples

Python with Standard Library

import math
import os

print("sqrt(16) =", math.sqrt(16))
print("Current dir:", os.getcwd())

class Person:
    def __init__(self, name):
        self.name = name

p = Person("Alice")

Python with Embedded Packages

# Install first: Ditto install requests
import requests

# Make HTTP requests (embedded implementation)
response = requests.get("https://api.example.com/data")
print(response.text)

JavaScript with require()

const fs = require('fs');
const path = require('path');

console.log("Current dir:", path.resolve('.'));

async function fetchData() {
    await Promise.resolve("data");
    console.log("Done!");
}

fetchData();

JavaScript with Embedded Packages

// Install first: Ditto install lodash
const _ = require('lodash');

const arr = [1, 2, 3, 4, 5];
const chunked = _.chunk(arr, 2);
console.log(chunked); // [[1,2], [3,4], [5]]

SQL with JOINs

CREATE TABLE users (id INTEGER, name TEXT);
CREATE TABLE orders (id INTEGER, user_id INTEGER, product TEXT);

SELECT users.name, orders.product
FROM users
JOIN orders ON users.id = orders.user_id;
