From 63e7e9d8b6483fed555ebed1c79a4820b2ba2558 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Micha=C5=82=20Kiedrowicz?= Date: Mon, 9 May 2011 23:52:05 +0200 Subject: git-grep: Learn PCRE MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch teaches git-grep the --perl-regexp/-P options (naming borrowed from GNU grep) in order to allow specifying PCRE regexes on the command line. PCRE has a number of features which make them more handy to use than POSIX regexes, like consistent escaping rules, extended character classes, ungreedy matching etc. git isn't build with PCRE support automatically. USE_LIBPCRE environment variable must be enabled (like `make USE_LIBPCRE=YesPlease`).
