@ -45,10 +45,47 @@ OPTIONS
|
||||
-S, --rev-file <revs-file>::
|
||||
Use revs from revs-file instead of calling gitlink:git-rev-list[1].
|
||||
|
||||
-f, --show-name::
|
||||
Show filename in the original commit. By default
|
||||
filename is shown if there is any line that came from a
|
||||
file with different name, due to rename detection.
|
||||
|
||||
-n, --show-number::
|
||||
Show line number in the original commit (Default: off).
|
||||
|
||||
-p, --porcelain::
|
||||
Show in a format designed for machine consumption.
|
||||
|
||||
-h, --help::
|
||||
Show help message.
|
||||
|
||||
|
||||
THE PORCELAIN FORMAT
|
||||
--------------------
|
||||
|
||||
In this format, each line is output after a header; the
|
||||
header at the minumum has the first line which has:
|
||||
|
||||
- 40-byte SHA-1 of the commit the line is attributed to;
|
||||
- the line number of the line in the original file;
|
||||
- the line number of the line in the final file;
|
||||
- on a line that starts a group of line from a different
|
||||
commit than the previous one, the number of lines in this
|
||||
group. On subsequent lines this field is absent.
|
||||
|
||||
This header line is followed by the following information
|
||||
at least once for each commit:
|
||||
|
||||
- author name ("author"), email ("author-mail"), time
|
||||
("author-time"), and timezone ("author-tz"); similarly
|
||||
for committer.
|
||||
- filename in the commit the line is attributed to.
|
||||
- the first line of the commit log message ("summary").
|
||||
|
||||
The contents of the actual line is output after the above
|
||||
header, prefixed by a TAB. This is to allow adding more
|
||||
header elements later.
