FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:

If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
To use Composer is sometimes complicated. Especially for beginners.
Composer needs much resources. Sometimes they are not available on a simple webspace.
If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Please rate this library. Is it a good library?

Informations about the package rule-contract

Aegisora Rule Contract

Rule Contract defines the core abstractions for building validation rules in the Aegisora ecosystem.

It provides:

a minimal, stable, and framework-agnostic contract that allows rules to be shared across packages and projects
a strict contract for implementing rules
consistent result handling
unified exception management

✨ Features

🔹 Lightweight, framework-agnostic design and dependency-free
🔹 Stable contract for validation rules
🔹 Unified validation result structure
🔹 Safe exception handling with execution wrapping
🔹 Automatic rule code generation
🔹 Supports both simple and complex rules
🔹 Designed for extensibility
🔹 Compatible with Aegisora ecosystem (guardian, rules, etc.)

📦 Installation

🚀 Core Concept

Each rule:

receives a Context
performs validation logic
returns a Result
never returns raw booleans
never throws unstructured exceptions

This ensures predictable and testable validation flow.

🏗️ Basic Usage

Creating a Rule

Extend the abstract Rule class (simple example):

Running a Rule

🏛️ Architecture

RuleInterface

Defines the contract for all rules:

validate(Context $context): Result

May throw:

InvalidRuleContextException
RuleException
RuleExecutionException

Rule (Abstract Class)

Base implementation that provides:

Safe execution layer
- wraps execution in try/catch
- rethrows domain exceptions as-is
- wraps unexpected errors into RuleExecutionException
Default helpers
- getDefaultValidResult()
- getDefaultInvalidResult()
Automatic rule code generation - generates snake_case code from class name:
- UserAgeRule → user_age_rule

Execution Flow

validate() is called
executeValidate() runs
Result handling:
- RuleException → rethrown
- Throwable → wrapped into RuleExecutionException
Result is returned

Context

Encapsulates input data for rule execution.

Context::create($value);

stores mixed value
provides getValue() access

Used to decouple rules from application structures.

Result

Standardized validation result object.

Structure

isValid: bool
failedRuleCode: ?string

Factory methods

Result::valid()
Result::invalid('rule_code')

Exception Handling

`RuleException`

Base exception for all rule-related errors.

`InvalidRuleContextException`

Thrown when context is invalid for a rule.

`RuleExecutionException`

Thrown when unexpected runtime error occurs during rule execution.

Contains:

rule class name (getRuleClassName())
original exception

Design Principles

This package enforces:

predictable execution flow
strict separation of concerns
consistent validation results
safe error boundaries
framework independence
testable business rules
