Kuhn" , Junio C Hamano , Brandon Casey , ZheNing Hu , ZheNing Hu Precedence: bulk List-ID: X-Mailing-List: git@vger.kernel.org From: ZheNing Hu Similar to "Helped-by", "Reported-by", "Reviewed-by", "Mentored-by" these signatures are often seen in git commit messages. After referring to the simple implementation of `commit --signoff` and `send-email -cc=" commiter "`, I am considering whether to provide multiple signature parameters from the command line. I think this might help maintainers and developers directly uses the shell to provide these signatures instead of multiple times repetitive writing those trailers each time. To achieve this goal, i refactored the `append_signoff` design and provided `append_message` and `append_message_string_list` interfaces, providing new ways to generate those various signatures. Users now can use `commit -H "helper "` to generate "Helped-by" trailer, `commit -R "reviewer "` to generate "Reviewed-by" trailer, `commit -r "reporter "`to generate "Reported-by" trailer, `commit -M "mentor "` to generate "Mentored-by" trailer. Signed-off-by: ZheNing Hu --- [GSOC] commit: provides multiple signatures from command line I don’t know if my idea will satisfy everyone, I'm also thinking about whether we can provide a more generalized version (I think this idea can be extended: because users and developers have other signature methods that they want, such as "Based-on-patch-by") I hope someone can give me pointers (on the correctness of ideas or codes) Published-As: https://github.com/gitgitgadget/git/releases/tag/pr-901%2Fadlternative%2Fcommit-with-multiple-signatures-v1 Fetch-It-Via: git fetch https://github.com/gitgitgadget/git pr-901/adlternative/commit-with-multiple-signatures-v1 Pull-Request: https://github.com/gitgitgadget/git/pull/901 Documentation/git-commit.txt | 24 +++++++- builtin/commit.c | 63 +++++++++++++++++++++ sequencer.c | 40 +++++++++---- sequencer.h | 4 ++ t/t7502-commit-porcelain.sh | 106 +++++++++++++++++++++++++++++++++++ 5 files changed, 226 insertions(+), 11 deletions(-) diff --git a/Documentation/git-commit.txt b/Documentation/git-commit.txt index 17150fa7eabe..e1b528d70c1a 100644 --- a/Documentation/git-commit.txt +++ b/Documentation/git-commit.txt @@ -14,7 +14,9 @@ SYNOPSIS [--allow-empty-message] [--no-verify] [-e] [--author=] [--date=] [--cleanup=] [--[no-]status] [-i | -o] [--pathspec-from-file= [--pathspec-file-nul]] - [-S[]] [--] [...] + [-S[]] [--] [...] [(-H|--helped-by)=
