BrickEngine

BrickEngine is a simple, flexible, and extensible script engine written in PHP. It allows you to manage custom business rules, e-commerce discounts, automation scenarios, or any workflow you define without "changing code."

Why Choose BrickEngine?

Features

• Dynamic Scripting Language: BrickEngine supports a wide range of operations through its flexible scripting language.
• Easy Extensibility: You can add your own functions (e.g., `apply_discount`, `dump`, `json_decode`) and variables to the context. All functions and variables must be explicitly defined and bound to BrickEngine.
• API & External Integrations: Whether for e-commerce, payment systems, or microservices, you can utilize scripts to make external API calls.
• Clean and Readable Syntax: Easily perform conditional operations using simple `if` structures, loops, and assignments.
• Performance and Flexibility: Centralize and manage your business rules to avoid complex branching and if-else chains.
• Support for Various Data Types: Operate on different data types, such as strings, numbers, booleans, and arrays.
• Loop and Conditional Structures: Includes support for control structures like `while`, `if-else`, and `for` loops.

Installation

Via Composer

composer require isaeken/brick-engine

Quick Start

The example below demonstrates a simple script that applies a discount if the cart total exceeds 100 units and then processes an e-commerce scenario by fetching a response from an external API.

<?php

require __DIR__ . '/vendor/autoload.php';

use IsaEken\BrickEngine\BrickEngine;

$script = <<<BRICK
if (cart['total'] > 100) {
    apply_discount();
    return "You have a discount!";
}

response = fetch('https://api.example.com');
response = json_decode(response);
return response['message'];
BRICK;

$engine = new BrickEngine();

// Define functions to be used within the script
$engine->context->functions['apply_discount'] = function () {
    $this->context->cart['total'] -= 10; // Apply a discount of 10 units
};

// Define variables to be used in the script
$engine->context->variables['cart'] = ['total' => 120];

$result = $engine->run($script)->value->data;
echo $result; // "You have a discount!" or API message

How It Works

1. The `BrickEngine` class interprets and executes the script.
2. Functions in the `context->functions` array can be directly accessed within the script.
3. The `context->variables` array defines variables that can be accessed in the script, such as `cart['total']`.

Running in Docker

You can run the example script in a Docker container using the following commands:

docker build -t brick-engine .
docker run --rm -v "$(pwd)":/app brick-engine ./examples/example.bee

Use Cases

• E-Commerce Rules: Create dynamic business rules for cart totals, shipping cost calculations, or payment steps.
• Form Validation / Workflow: Process user inputs and direct them to different scenarios.
• Content Management: Apply dynamic rule sets for news, blogs, or similar content platforms.
• API & Microservice Integration: Manage external API calls based on specific conditions (e.g., order confirmation, payment processing).
• Game / Application Logic: Manage simple rule sets for game servers or create rapid prototypes using mini-scripts within applications.
