From: ZheNing Hu via GitGitGadget Date: Sun, 14 Mar 2021 13:02:57 GMT Subject: [PATCH v3] [GSOC] commit: add --trailer option Message-ID: In-Reply-To: From: ZheNing Hu Historically, Git has supported the 'Signed-off-by' commit trailer using the '--signoff' and the '-s' option from the command line. But users may need to provide other trailer information from the command line such as "Helped-by", "Reported-by", "Mentored-by", Now implement a new `--trailer [(=|:)]` option to pass other trailers to `interpret-trailers` and insert them into commit messages. Signed-off-by: ZheNing Hu --- [GSOC] commit: add --trailer option Now maintainers or developers can also use commit --trailer="Signed-off-by:commiter" from the command line to provide trailers to commit messages. This solution may be more generalized than v1.
