Introduce new pretty formats %g[sdD] for reflog information
Add three new --pretty=format escapes: %gD long reflog descriptor (e.g. refs/stash@{0}) %gd short reflog descriptor (e.g. stash@{0}) %gs reflog message This is achieved by passing down the reflog info, if any, inside the pretty_print_context struct. We use the newly refactored get_reflog_selector(), and give it some extra functionality to extract a shortened ref. The shortening is cached inside the commit_reflogs struct; the only allocation of it happens in read_complete_reflog(), where it is initialised to 0. Also add another helper get_reflog_message() for the message extraction. Note that the --format="%h %gD: %gs" tests may not work in real repositories, as the --pretty formatter doesn't know to leave away the ": " on the last commit in an incomplete (because git-gc removed the old part) reflog. This equivalence is nevertheless the main goal of this patch. Thanks to Jeff King for reviews, the %gd testcase and documentation. Signed-off-by: Thomas Rast <> Signed-off-by: Junio C Hamano <>
