[PATCH v2 5/9] commit: move print_commit_summary() to libgit

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Phillip Wood <phillip.wood@xxxxxxxxxxxxx>

Move print_commit_summary() from builtin/commit.c to sequencer.c so it
can be shared with other commands. The function is modified by
changing the last argument to a flag so callers can specify whether
they want to show the author date in addition to specifying if this is
an initial commit.

Signed-off-by: Phillip Wood <phillip.wood@xxxxxxxxxxxxx>

Notes:
    changes since v1:
     - convert flags passed to print_commit_summary() to unsigned int
