Subject: [PATCH v6 3/3] ls-files.c: add --deduplicate option
Date: Sat, 23 Jan 2021 10:20:10 +0000 [thread overview]
Message-ID: <07b603fd97c0e2d7a70407da552c3c0658a84731.1611397210.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.832.v6.git.1611397210.gitgitgadget@gmail.com>
From: ZheNing Hu <adlternative@gmail.com>
In order to provide users a better experience
when viewing information about files in the index
and the working tree, the `--deduplicate` option will suppress
some duplicate name under some conditions.
In a merge conflict, one file name of "git ls-files" output may
appear multiple times. For example,now there is an unmerged path
`a.c`,`a.c` will appear three times in the output of
"git ls-files".We can use "git ls-files --deduplicate" to output
`a.c` only one time.(unless `--stage` or `--unmerged` is
used to view all the detailed information in the index)
In addition, if you use both `--delete` and `--modify` at
the same time, The `--deduplicate` option
can also suppress file name output.
Additional instructions:
In order to display entries information,`deduplicate` suppresses
the output of duplicate file names, not the output of duplicate
entries information, so under the option of `-t`, `--stage`, `--unmerge`,
`--deduplicate` will have no effect.
