Blasp - Profanity Filter for Laravel

Blasp is a profanity filter package for Laravel that helps detect and mask profane words in a given sentence. It offers a robust set of features for handling variations of offensive language, including substitutions, obscured characters, and doubled letters.

Installation

You can install the package via Composer:

composer require blaspsoft/blasp

Usage

Basic Usage

To use the profanity filter, simply call the Blasp::check() method with the sentence you want to check for profanity.

use Blaspsoft\Blasp\Facades\Blasp;

$sentence = 'This is a fucking shit sentence';
$check = Blasp::check($sentence);

The returned object will contain the following properties:

• sourceString: The original string you passed.
• cleanString: The string with profanities masked (e.g., replaced with *).
• hasProfanity: A boolean indicating whether the string contains profanity.
• profanitiesCount: The number of profanities found.
• uniqueProfanitiesFound: An array of unique profanities found in the string.

Example

$sentence = 'This is a fucking shit sentence';
$blasp = Blasp::check($sentence);

$blasp->getSourceString();       // "This is a fucking shit sentence"
$blasp->getCleanString();        // "This is a ******* **** sentence"
$blasp->hasProfanity();       // true
$blasp->getProfanitiesCount();   // 2
$blasp->getUniqueProfanitiesFound(); // ['fucking', 'shit']

Profanity Detection Types

Blasp can detect different types of profanities based on variations such as:

1. Straight match: Direct matches of profane words.
2. Substitution: Substituted characters (e.g., pro0fán1ty).
3. Obscured: Profanities with separators (e.g., p-r-o-f-a-n-i-t-y).
4. Doubled: Repeated letters (e.g., pprrooffaanniittyy).
5. Combination: Combinations of the above (e.g., pp-rof@n|tty).

Laravel Validation Rule

Blasp also provides a custom Laravel validation rule called blasp_check, which you can use to validate form input for profanity.

Example

$request->merge(['sentence' => 'This is f u c k 1 n g awesome!']);

$validated = $request->validate([
    'sentence' => ['blasp_check'],
]);

// If the sentence contains profanities, validation will fail.

Configuration

Blasp uses a configuration file (config/blasp.php) to manage the list of profanities, separators, and substitutions. You can publish the configuration file using the following Artisan command:

php artisan vendor:publish --tag="blasp-config"
