From 2708ce62d2105c4470399a2c839b6d451c9c148f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Thu, 7 Jan 2021 10:51:52 +0100 Subject: [PATCH] branch: sort detached HEAD based on a flag MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Change the ref-filter sorting of detached HEAD to check the FILTER_REFS_DETACHED_HEAD flag, instead of relying on the ref description filled-in by get_head_description() to start with "(", which in turn we expect to ASCII-sort before any other reference. For context, we'd like the detached line to appear first at the start of "git branch -l", e.g.: $ git branch -l * (HEAD detached at ) master This doesn't change that, but improves on a fix made in 28438e84e04 (ref-filter: sort detached HEAD lines firstly, 2019-06-18) and gives the Chinese translation the ability to use its preferred punctuation marks again. In Chinese the fullwidth versions of punctuation like "()" are typically written as (U+FF08 fullwidth left parenthesis), (U+FF09 fullwidth right parenthesis) instead[1]. This form is used in both po/zh_{CN,TW}.po in most cases where "()" is translated in a string. Aside from that improvement to the Chinese translation, it also just makes for cleaner code that we mark any special cases in the ref_array we're sorting with flags and make the sort function aware of them, instead of piggy-backing on the general-case of strcmp() doing the right thing. As seen in the amended tests this made reverse sorting a bit more consistent. Before this we'd sometimes sort this message in the middle, now it's consistently at the beginning or end, depending on whether we're doing a normal or reverse sort. Having it at the end doesn't make much sense either, but at least it behaves consistently now. A follow-up commit will make this behavior under reverse sorting even better. I'm removing the "TRANSLATORS" comments that were in the old code while I'm at it. Those were added in d4919bb288e (ref-filter: move get_head_description() from branch.c, 2017-01-10). I think it's obvious from context, string and translation memory in typical translation tools that these are the same or similar string. 1. https://en.wikipedia.org/wiki/Chinese_punctuation#Marks_similar_to_European_punctuation Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano --- builtin/branch.c | 2 ++ ref-filter.c | 44 +++++++++++++++++++++++----------------- ref-filter.h | 1 + t/t3203-branch-output.sh | 4 ++-- wt-status.c | 4 ++-- wt-status.h | 2 -- 6 files changed, 32 insertions(+), 25 deletions(-) diff --git a/builtin/branch.c b/builtin/branch.c index 2dd51a8653b..8c0b428104d 100644 --- a/builtin/branch.c +++ b/builtin/branch.c @@ -740,6 +740,8 @@ int cmd_branch(int argc, const char **argv, const char *prefix) if (!sorting) sorting = ref_default_sorting();
