a fraction, with a decimal point before it. I.e., <code>-M5</code> becomes

|
0.5, and is thus the same as <code>-M50</code>%. Similarly, <code>-M05</code> is

<p>This flag changes the way a merge commit patch is displayed,

by omitting uninteresting hunks whose contents in the parents

have only two variants and the merge result picks one of them

effect when -c or --cc are specified, and is likely only

useful if filename changes are detected (i.e. when either

"CONFIGURATION FILE" section of <a href="git-config.html">git-config(1)</a>. By

default, colors are shown only when enabled for log output
|
|
(by <code>color.diff</code>, <code>color.ui</code>, or <code>--color</code>, and respecting
|
|
the <code>auto</code> settings of the former if we are going to a
|
|
terminal). %C(<code>auto,</code><code>...</code>) is accepted as a historical
|
|
synonym for the default (e.g., %C(<code>auto,red</code>)). Specifying
|
|
%C(<code>always,</code><code>...</code>) will show the colors even when color is
|
|
not otherwise enabled (though consider just using
|
|
<code>--color=always</code> to enable color for the whole output,
|
|
including this format and anything else git might color).
|
|
<code>auto</code> alone (i.e. %C(<code>auto</code>)) will turn on auto coloring

again.</p>

case-insensitively and trailing colon is optional. If option is

non-trailer lines in the trailer block are hidden. If that is not

desired it can be disabled with <code>only=false</code>. E.g.,

the literal formatting codes described above. To use comma as

separator one must use %x2C as it would otherwise be parsed as

|
|
<p>The <em>tformat:</em> format works exactly like <em>format:</em>, except that it
|
|
provides "terminator" semantics instead of "separator" semantics. In
|
|
other words, each commit has the message terminator character (usually a
|
|
newline) appended, rather than a separator placed between entries.
|
|
This means that the final entry of a single-line format will be properly
|
|
terminated with a new line, just as the "oneline" format does.
|
|
For example:</p>
|
|
</div>
|
|
<div class="listingblock">
|
|
<div class="content">
|
|
<pre>$ git log -2 --pretty=format:%h 4da45bef \

|
|
4da45be
|
|
7134973 -- NO NEWLINE
|
|
|
|
$ git log -2 --pretty=tformat:%h 4da45bef \
|
|
| perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'

|
|
<div class="paragraph">
|
|
<p>In addition, any unrecognized string that has a % in it is interpreted

as if it has <code>tformat:</code> in front of it. For example, these two are

equivalent:</p>

<p>Unlike the traditional <em>unified</em> diff format, which shows two

files A and B with a single column that has <code>-</code> (minus — appears in A but removed in B), <code>+</code> (plus — missing in A but
|
|
added to B), or " " (space — unchanged) prefix, this format
|
|
compares two or more files file1, file2,…​ with one file X, and
|
|
shows how X differs from each of fileN. One column for each of
|
|
fileN is prepended to the output line to note how X’s line is

different from it.</p>

<p>A <code>-</code> character in the column N means that the line appears in

in the column N means that the line appears in the result,

|
and fileN does not have that line (in other words, the line was

|
added, from the point of view of that parent).</p>

</div>

<div class="paragraph">
|

<p>In the above example output, the function signature was changed

|
from both files (hence two <code>-</code> removals from both file1 and

|
file2, plus <code>++</code> to mean one line that was added does not appear
|
|
in either file1 or file2). Also, eight other lines are the same
|

from file1 but do not appear in file2 (hence prefixed with <code>+</code>).</p>

|

two unresolved merge parents with the working tree file

"their version").</p>

<p>The <code>--summary</code> option describes newly added, deleted, renamed and

<p>When showing a change that involves a rename or a copy, <code>--stat</code> output
