Simplify diff

Little tool to simplify unified diffs, e.g. to remove lines only containing whitespace changes

Installation

My homepages provides standalone simplify diff binaries for Windows and Linux.

If you want to compile it, you need Lazarus and my rcmdline unit. Then just open simplifydiff.lpi in Lazarus and click compile.

Usage

It is a commandline program, so you can simply call it with:

simplifydiff < broken.diff > improved.diff

simplifydiff --help prints more advanced option.

Example

A too verbose diff like:

+new

is simplified to
