From 2fa9a0fb31cbf01e8318a02c3e222d7fd3fd0a83 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Tue, 2 May 2006 14:22:48 +0200 Subject: [PATCH 1/3] repo-config: support --get-regexp With --get-regexp, output all key/value pairs where the key matches a regexp. Example: git-repo-config --get-regexp remote.*.url will output something like remote.junio.url git://git.kernel.org/pub/scm/git/git.git remote.gitk.url git://git.kernel.org/pub/scm/gitk/gitk.git Signed-off-by: Johannes Schindelin Signed-off-by: Junio C Hamano --- Documentation/git-repo-config.txt | 5 +++- repo-config.c | 40 +++++++++++++++++++++++++------ t/t1300-repo-config.sh | 23 ++++++++++++++++++ 3 files changed, 60 insertions(+), 8 deletions(-) diff --git a/Documentation/git-repo-config.txt b/Documentation/git-repo-config.txt index 566cfa1836..ddcf52364c 100644 --- a/Documentation/git-repo-config.txt +++ b/Documentation/git-repo-config.txt @@ -49,7 +49,7 @@ OPTIONS --replace-all:: Default behaviour is to replace at most one line.
