FAQ
Example:
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 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.
Informations about the package emptiness-rule
Aegisora Emptiness Rule
Emptiness Rule provides a simple, rule-based emptiness validation implementation for the Aegisora ecosystem.
It is built on top of aegisora/rule-contract (https://github.com/Aegisora/rule-contract) and follows its strict validation architecture, ensuring consistent and predictable behavior across applications.
✨ Features
- 🔹 Lightweight and minimal dependencies
- 🔹 Validation for empty and non-empty values
- 🔹 Supports multiple data types (string, array, object, etc.)
- 🔹 Fully compatible with Aegisora validation pipeline
- 🔹 Strict
Context → Resultvalidation flow - 🔹 No raw booleans — only structured results
- 🔹 Safe execution via base
Ruleabstraction - 🔹 Convenient factory methods (
create()) - 🔹 Built-in validation of input values
📦 Installation
🚀 Core Concept
This package provides validation rules to check whether a value is:
- empty (
EmptyRule) - not empty (
NotEmptyRule)
Validation is performed by:
- receiving a value via
Context - checking it against emptiness criteria
- returning a standardized
Result
📐 What is "empty"?
The following values are considered empty:
null- empty string (
'') - empty array (
[]) - objects implementing
Countablewithcount() === 0
The following are NOT empty:
- non-empty strings
- non-empty arrays
- numbers (
int,float) - booleans
- objects (unless
Countableand empty)
🏗️ Basic Usage
✅ Check if value is NOT empty
❌ Check if value is empty
🧩 Available Rules
Both rules:
- accept any value via
Context - return a structured
Result - follow identical validation logic with inverted outcomes
⚠️ Validation Rules
Supported input types:
nullstringarrayintfloatboolobject(with special handling forCountable)
Unsupported types will throw:
Aegisora\RuleContract\Exceptions\InvalidRuleContextException
🏛️ Architecture
This package relies on aegisora/rule-contract (https://github.com/Aegisora/rule-contract).
Validation flow:
validate()is calledContextis passed inexecuteValidate()runs- Value is checked for emptiness
- Result is determined (valid / invalid)
Resultis returned
All logic is safely encapsulated within the base Rule abstraction.
