From 2ae1c53b51ff78b13cc8abf8e9798a12140b7638 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Mon, 27 Feb 2006 14:47:45 -0800 Subject: [PATCH] apply --whitespace: configuration option. The new configuration option apply.whitespace can take one of "warn", "error", "error-all", or "strip". When git-apply is run to apply the patch to the index, they are used as the default value if there is no command line --whitespace option. Andrew can now tell people who feed him git trees to update to this version and say: git repo-config apply.whitespace error Signed-off-by: Junio C Hamano --- apply.c | 72 +++++++++++++++++++++++++++++++++++++++-------------------- cache.h | 2 ++ environment.c | 1 + 3 files changed, 51 insertions(+), 24 deletions(-) diff --git a/apply.c b/apply.c index 8139d832..a5cdd8e2 100644 --- a/apply.c +++ b/apply.c @@ -35,16 +35,42 @@ static const char apply_usage[] = "git-apply [--stat] [--numstat] [--summary] [--check] [--index] [--apply] [--no-add] [--index-info] [--allow-binary-replacement] [-z] [-pNUM] ..."; static enum whitespace_eol { - nowarn, + nowarn_whitespace, warn_on_whitespace, error_on_whitespace, - strip_and_apply, -} new_whitespace = nowarn; + strip_whitespace, +} new_whitespace = nowarn_whitespace; static int whitespace_error = 0; static int squelch_whitespace_errors = 5; static int applied_after_stripping = 0; static const char *patch_input_file = NULL; +static void parse_whitespace_option(const char *option) +{ + if (!option) { + new_whitespace = nowarn_whitespace; + return; + } + if (!strcmp(option, "warn")) { + new_whitespace = warn_on_whitespace; + return; + } + if (!strcmp(option, "error")) { + new_whitespace = error_on_whitespace; + return; + } + if (!strcmp(option, "error-all")) { + new_whitespace = error_on_whitespace; + squelch_whitespace_errors = 0; + return; + } + if (!strcmp(option, "strip")) { + new_whitespace = strip_whitespace; + return; + } + die("unrecognized whitespace option '%s'", option); +} + /* * For "diff-stat" like behaviour, we keep track of the biggest change * we've seen, and the longest filename.
