Exprc
=====

[](#exprc)

Exprc is a tiny, decoupled rule engine for PHP

It parses rule strings into an AST once, then lets you evaluate that AST with different backends:

- in-memory records
- Laravel query builders
- custom callback handlers

Prerequisites
-------------

[](#prerequisites)

- PHP 8.2+

Install
-------

[](#install)

```
composer require kevintherm/exprc
```

For Laravel QueryBuilder support:

```
composer require illuminate/database
```

Architecture
------------

[](#architecture)

Rule string -> Lexer -> Parser -> AST -> Evaluator

Core parser and AST are framework-agnostic. Evaluators are swappable adapters.

Supported Operators
-------------------

[](#supported-operators)

- `=` / `!=`
- `>` / `>=` / `
