README
JBDiff
A multi-line diff calculation library based on Jetbrains' powerful IDE diff implementation.
https://github.com/JetBrains/intellij-community/tree/master/platform/util/diff/src/com/intellij/diff
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);
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.
