Installation

composer require digitalrevolution/jbdiff

Usage

$textBefore:

switch ($strategy) {
    case RateLimiterConfig::FIXED_WINDOW:
        return new FixedWindow($this->redisService->getConnection(), $config);
    case RateLimiterConfig::SLIDING_WINDOW:
        return new SlidingWindow($this->redisService->getConnection(), $config);
    default:
        throw new RuntimeException('Invalid Strategy name.', RuntimeException::UNKNOWN);
}

$textAfter:

return match ($strategy) {
    RateLimiterConfig::FIXED_WINDOW   => new FixedWindow($this->redisService->getConnection(), $config),
    RateLimiterConfig::SLIDING_WINDOW => new SlidingWindow($this->redisService->getConnection(), $config),
    default                           => throw new RuntimeException('Invalid Strategy name.'),
};

To create the diff:

use DR\JBDiff\ComparisonPolicy;
use DR\JBDiff\JBDiff;

// line block will contain all the information to partition the strings in removed, unchanged and added parts.
$lineBlocks = (new JBDiff())->compare($textBefore, $textAfter, ComparisonPolicy::DEFAULT);

// to iterate over the string parts
$iterator = new LineBlockTextIterator($textBefore, $textAfter, $lineBlocks);

$iterator formatted to html:

with ComparisonPolicy::IGNORE_WHITESPACES

Comparison policies

• DEFAULT: the standard diff strategy and will take whitespace differences into account.
• TRIM_WHITESPACES: will take leading and trailing whitespaces out of the diff.
• IGNORE_WHITESPACES: will take all whitespace differences out of the diff.
