Adjust a now-redundant assignment to extended_regexp_option to make it zero if grep.extendedRegexp is not set. This is always called right after init_grep_defaults() which memsets the entire structure to 0, so there's no need to set it again to zero.
However the reason for the if/else pattern is a holdover from[1] where this was adjusted from a bitfield assignment to a boolean. Rather than getting rid of the assignment to 0 in all cases, let's just use the value returned by git_config_bool(), which is more idiomatic and in sync with the rest of the boolean handling in this function. This is a logical follow-up to my commit to remove redundant regflags assignments[2]. This logic was originally introduced in [3], but as explained in the former commit it's working around a pattern in our code that no longer exists, and is now confusing as it leads the reader to think that this needs to be flipped back & forth. 1. 84befcd0a4 ("grep: add a grep.patternType configuration setting", 2012-08-03) 2. e0b9f8ae09 ("grep: remove redundant regflags assignments", 2017-05-25) 3. b22520a37c ("grep: allow -E and -n to be turned on by default via configuration", 2011-03-30) Signed-off-by: Ævar Arnfjörð Bjarmason <ava...@gmail.com> --- grep.c | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) diff --git a/grep.c b/grep.c index 29439886e7..817270d081 100644 --- a/grep.c +++ b/grep.c @@ -78,10 +78,7 @@ int grep_config(const char *var, const char *value, void *cb) return -1; if (!strcmp(var, "grep.extendedregexp")) { - if (git_config_bool(var, value)) - opt->extended_regexp_option = 1; - else - opt->extended_regexp_option = 0; + opt->extended_regexp_option = git_config_bool(var, value); return 0; } -- 2.13.1.611.g7e3b11ae1
