Usage: $ME [OPTIONS] [ARGS]
Convert git log output to ChangeLog format. If present, any ARGS
are passed to "git log". To avoid ARGS being parsed as options to
$ME, they may be preceded by '--'.
OPTIONS:
--amend=FILE FILE maps from an SHA1 to perl code (i.e., s/old/new/) that
makes a change to SHA1's commit log text or metadata.
--append-dot append a dot to the first line of each commit message if
there is no other punctuation or blank at the end.
--no-cluster never cluster commit messages under the same date/author
header; the default is to cluster adjacent commit messages
if their headers are the same and neither commit message
contains multiple paragraphs.
--srcdir=DIR the root of the source tree, from which the .git/
directory can be derived.
--since=DATE convert only the logs since DATE;
the default is to convert all log entries.
--format=FMT set format string for commit subject and body;
see 'man git-log' for the list of format metacharacters;
the default is '%s%n%b%n'
--strip-tab remove one additional leading TAB from commit message lines.
--strip-cherry-pick remove data inserted by "git cherry-pick";
this includes the "cherry picked from commit ..." line,
and the possible final "Conflicts:" paragraph.
--help display this help and exit
--version output version information and exit
EXAMPLE:
$ME --since=2008-01-01 > ChangeLog
$ME -- -n 5 foo > last-5-commits-to-branch-foo
SPECIAL SYNTAX:
The following types of strings are interpreted specially when they appear
at the beginning of a log message line. They are not copied to the output.
Copyright-paperwork-exempt: Yes
Append the "(tiny change)" notation to the usual "date name email"
ChangeLog header to mark a change that does not require a copyright
assignment.
Co-authored-by: Joe User <user\@example.com>
List the specified name and email address on a second
ChangeLog header, denoting a co-author.
Signed-off-by: Joe User <user\@example.com>
These lines are simply elided.
In a FILE specified via --amend, comment lines (starting with "#") are ignored.
FILE must consist of <SHA,CODE+> pairs where SHA is a 40-byte SHA1 (alone on
a line) referring to a commit in the current project, and CODE refers to one
or more consecutive lines of Perl code. Pairs must be separated by one or
more blank line.
Here is sample input for use with --amend=FILE, from coreutils:
