A comprehensive library for generating diff between two strings.

Introduction
------------

[](#introduction)

Generated diff can be rendered in all of the standard formats including:

**Text** renderers:

- Context
- Json (plain text)
- Unified

**HTML** renderers:

- Combined
- Inline
- Json (HTML)
- Side by Side

Note that for HTML rendered results, you have to add CSS for a better visualization. You may modify one from `example/diff-table.css` or write your own from zero.

If you are okay with the default CSS, there is `\Jfcherng\Diff\DiffHelper::getStyleSheet()`which can be used to get the content of the `example/diff-table.css`.
