Subject: [PATCH 4/4] [GSOC] ref-filter: add %(rest) atom
Date: Tue, 08 Jun 2021 14:38:02 +0000 [thread overview]
Message-ID: <5e95292e3de269a688288055b1cede951dfcc24a.1623163082.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.976.git.1623163082.gitgitgadget@gmail.com>
From: ZheNing Hu <adlternative@gmail.com>
In order to let "cat-file --batch=%(rest)" use the ref-filter
interface, add %(rest) atom for ref-filter. "git for-each-ref",
"git branch", "git tag" and "git verify-tag" will reject %(rest)
by default.
