Download the PHP package alazzi-az/laravel-bitmask without Composer

laravel package to work with bitmasking

Laravel Bitmask is a powerful wrapper package for integrating the functionality of the php-bitmask library into Laravel applications. It leverages Laravel's service container and facades to provide an elegant and intuitive interface for reading, validating, and converting bitmasks. The package also simplifies casting bitmasks to and from enum values, enabling developers to efficiently apply bitmasking techniques while harnessing the full power of Laravel’s ecosystem.## Features

• Bitmask Reading: Easily retrieve active bits from a given bitmask.
• Bitmask Validation: Ensure that provided bits and masks are valid, including checks for single-bit settings.
• Bitmask Conversion: Convert indices to bitmasks and vice versa, along with conversions to binary string representations.
• Casting for Masks and Enums: Automatically handle the casting of bitmask values to and from enum types, providing a seamless experience when working with enumerated bitmasks.
• Integration with Laravel: Utilizes Laravel's facade system for seamless integration and easy access.

Installation

You can install the package via composer:

Usage

EnumBitmaskCast

Overview

EnumBitmaskCast is a custom attribute casting class that converts a bitmask integer into an enum-based object. This allows you to leverage PHP enums in your models for cleaner and more expressive code.

Usage

To use EnumBitmaskCast in your model, specify the cast in the $casts property:

Example

BitmaskCast

Overview

BitmaskCast is another custom attribute casting class that handles integer bitmask values. It allows you to work with bitmask values more easily in your models.

Usage

To use BitmaskCast in your model, specify the cast in the $casts property:

Example

Conclusion

You can now easily use EnumBitmaskCast and BitmaskCast in your Laravel models to handle bitmasking and enums efficiently. This allows for clearer and more maintainable code in your application.

BitmaskHandler

The BitmaskHandler class provides an interface for managing bitmask operations in a Laravel application. It allows for the manipulation of bitmasks through various methods, including adding, deleting, and checking for specific bits.

EnumBitmaskHandler

The EnumBitmaskHandler class provides an interface for managing bitmask operations specific to enumerations in a Laravel application. It allows manipulation of bitmasks using enums, enabling you to add, delete, and check for specific bits represented by these enums.

Methods Overview

• remove(UnitEnum ...$bits): self

  • Removes specified bits from the current instance.

• add(UnitEnum ...$bits): self

  • Adds specified bits to the current instance.

• getValue(): int

  • Returns the current mask value as an integer.

• toArray(): array

  • Returns an array representation of the current mask, indicating which bits are set.
• has(UnitEnum ...$bits): bool
  • Checks if the specified bits are set in the current mask.

Example Usage

Here's an example that illustrates how to use the EnumBitmaskHandler class:

Note on toArray Method

If you want to customize the keys in the resulting array from the toArray method, consider implementing the Alazziaz\Bitmask\Contracts\MaskableEnum interface for your enum. You can define a toMaskKey method to specify custom keys for each enum value. For example:

With this approach, the toArray method in EnumBitmaskHandler can utilize the toMaskKey method to generate a more descriptive and meaningful array representation of the current mask.
