[Python/JS/C#] Block Engine v2.2.0: Run Python, Node.js, Lua & PHP in a single document with zero-config state pipeline

Hi everyone,

I want to share Block Engine v2.2.0, an open-source polyglot multi-runtime execution engine designed to eliminate the friction of combining multiple programming languages in software development.

💡 Why Block Engine?

Modern applications often leverage different languages for their unique strengths:

Python for machine learning, data science, and analytics.
Node.js for async Web APIs and NPM packages.
Lua for ultra-fast, lightweight embedded calculations (< 300KB RAM footprint).
PHP for web string formatting and cryptographic hashing (hash, openssl).

Traditionally, orchestrating these runtimes requires setting up microservices, gRPC, Docker containers, or manual JSON IPC file reading/writing.

Block Engine solves this by introducing a Zero-Dependency Polyglot Pipeline.

⚡ How It Works (.blkp Polyglot Document)

You write native code blocks (<py>, <js>, <lua>, <php>) inside a single .blkp document. Block Engine parses the AST, executes each runtime in isolated subprocesses, and automatically serializes and transfers state variables from one language to the next.


html
<py>
# Python Stage: Compute analytics data
raw_prices = [100.5, 102.1, 101.8, 105.4, 108.0]
ma5 = sum(raw_prices) / len(raw_prices)
user_name = "Gemini Master"
</py>

<js>
// Node.js Stage: Automatically receives Python variables (user_name, ma5)
console.log(`[Node.js] Received user: ${user_name}, MA5: ${ma5.toFixed(2)}`);
var final_score = Math.round(ma5);
</js>

<lua>
-- Lua 5.4 Stage: High-speed recursive computation
function fib(n)
    if n <= 1 then return n end
    return fib(n-1) + fib(n-2)
end
lua_result = fib(10)
</lua>

<php>
// PHP 8 Stage: Cryptographic SHA-256 Signature
$signature = hash('sha256', $user_name . '|' . $final_score);
echo "[PHP] Audit SHA-256: " . $signature . "\n";
</php>
