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:
