From 7e8f59d577e5615ceff06da0d9dde36a63608d53 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ren=C3=A9=20Scharfe?= Date: Sat, 7 Mar 2009 13:32:32 +0100 Subject: grep: color patterns in output MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Coloring matches makes them easier to spot in the output. Add two options and two parameters: color.grep (to turn coloring on or off), color.grep.match (to set the color of matches), --color and --no-color (to turn coloring on or off, respectively). The output of external greps is not changed. This patch is based on earlier ones by Nguyễn Thái Ngọc Duy and Thiago Alves.
