From 4914c9629c046f7f5abf4109ad756040f9ebe2bf Mon Sep 17 00:00:00 2001 From: =?utf8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Fri, 26 Oct 2012 22:53:52 +0700 Subject: [PATCH] Move setup_diff_pager to libgit.a MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This is used by diff-no-index.c, part of libgit.a while it stays in builtin/diff.c. Move it to diff.c so that we won't get undefined reference if a program that uses libgit.a happens to pull it in. While at it, move check_pager from git.c to pager.c. It makes more sense there and pager.c is also part of libgit.a Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Jeff King --- builtin.h | 4 ---- builtin/diff.c | 16 ---------------- cache.h | 1 + diff.c | 16 ++++++++++++++++ diff.h | 1 + git.c | 33 --------------------------------- pager.c | 34 ++++++++++++++++++++++++++++++++++ 7 files changed, 52 insertions(+), 53 deletions(-) diff --git a/builtin.h b/builtin.h index 95116b853..3faf9d669 100644 --- a/builtin.h +++ b/builtin.h @@ -37,10 +37,6 @@ int copy_note_for_rewrite(struct notes_rewrite_cfg *c, const unsigned char *from_obj, const unsigned char *to_obj); void finish_copy_notes_for_rewrite(struct notes_rewrite_cfg *c); -extern int check_pager_config(const char *cmd); -struct diff_options; -extern void setup_diff_pager(struct diff_options *); - extern int textconv_object(const char *path, unsigned mode, const unsigned char *sha1, int sha1_valid, char **buf, unsigned long *buf_size); extern int cmd_add(int argc, const char **argv, const char *prefix); diff --git a/builtin/diff.c b/builtin/diff.c index 9650be2c5..9c70e4080 100644 --- a/builtin/diff.c +++ b/builtin/diff.c @@ -418,19 +418,3 @@ int cmd_diff(int argc, const char **argv, const char *prefix) refresh_index_quietly(); return result; } - -void setup_diff_pager(struct diff_options *opt) -{ - /* - * If the user asked for our exit code, then either they want --quiet - * or --exit-code.
