README

A stateful, in-memory PHP text editor for making and inspecting changes without file I/O. It keeps the original content and edit history, making changes easy to review or revert.

Features

• Replace, insert, and delete text fragments or line ranges.
• Apply regular-expression replacements.
• Read line ranges and inspect the edit history.
• Revert the most recent operation or restore the original content.
• Generate structured hunks or a unified diff.
• Supply a custom diff implementation through TextDiffInterface.

Installation

Install the library with Composer:

composer require adachsoft/text-editor

Quick start

<?php

declare(strict_types=1);

use AdachSoft\TextEditor\TextEditor;

$editor = new TextEditor("Hello, world!\n");
$editor->replaceFragment('world', 'PHP');

echo $editor->getText(); // Hello, PHP!
echo $editor->diffUnified();

$editor->revert();

See the examples for more editing operations.
