When comparing files, <span class="application">KDiff3</span> first it tries to match lines that are equal
in all input files. Only during this step it might ignore white space. The
second step compares each line. In this step white space will not be ignored.
Also during the merge white space will not be ignored.
</p><div class="variablelist"><dl><dt><span class="term"><span class="emphasis"><em>Preserve Carriage Return:</em></span></span></dt><dd><p> Some editors (on some systems) save
carriage return '\r' and linefeed '\n'-characters at the end of line, while
others will only save the linefeed '\n'. Usually <span class="application">KDiff3</span> ignores the carriage
return, but then files that don't have equal sizes, look equal in side by
side comparison. When this option is on, then the carriage return characters
are made visible but are treated as white space. This option must be off
during a merge. Default is off.</p></dd><dt><span class="term"><span class="emphasis"><em>Ignore numbers:</em></span></span></dt><dd><p> Default is off. Number characters ('0'-'9', '.', '-')
will be ignored in the first part of the analysis in which the line matching is
done. In the result the differences will be shown nevertheless, but they are treated
as white space.
</p></dd><dt><span class="term"><span class="emphasis"><em>Ignore C/C++ comments:</em></span></span></dt><dd><p> Default is off.
Changes in comments will be treated like changes in white space.
</p></dd><dt><span class="term"><span class="emphasis"><em>Ignore case:</em></span></span></dt><dd><p> Default is off.
Case-differences of characters (like 'A' vs. 'a') will be treated like changes in white space.

</p></dd><dt><span class="term"><span class="emphasis"><em>Try Hard:</em></span></span></dt><dd><p>
Try hard to find an even smaller delta. (Default is on.) This will probably
be effective for complicated and big files. And slow for very big files.

how long to show the result of the selection before jumping to the next unsolved
conflict.
</p></dd><dt><span class="term"><span class="emphasis"><em>White space 2/3-file merge default:</em></span></span></dt><dd><p>
Automatically solve all white-space conflict by choosing the specified file.
(Default is manual choice.) Useful if white space really isn't important in many files.
If you need this only occasionally better use "Choose A/B/C For All Unsolved Whitespace Conflicts"
in the merge menu. Note that if you enable either "Ignore numbers" or "Ignore C/C++ comments"
then this auto-choice also applies for conflicts in numbers or comments.
</p></dd><dt><span class="term"><span class="emphasis"><em>Auto merge regular expression:</em></span></span></dt><dd><p>
Regular expression for lines where <span class="application">KDiff3</span> should automatically choose one source. See also <a href="merging.html#vcskeywordsmergesupport" title="Automatic Merge of Version Control Keywords and History (Log)">Automatic Merge ...</a>
</p></dd><dt><span class="term"><span class="emphasis"><em>Run regular expression auto merge on merge start:</em></span></span></dt><dd><p>

</p></dd><dt><span class="term"><span class="emphasis"><em>History start regular expression:</em></span></span></dt><dd><p>
Regular expression for the start of the merge history entry.
Usually this line contains the "$Log$"-keyword.
Default value: ".*\$Log.*\$.*"
</p></dd><dt><span class="term"><span class="emphasis"><em>History entry start regular expression:</em></span></span></dt><dd><p>
A merge history entry consists of several lines.
Specify the regular expression to detect the first line (without the leading comment).
Use parentheses to group the keys you want to use for sorting.
If left empty, then <span class="application">KDiff3</span> assumes that empty lines separate history entries.
See also <a href="merging.html#vcskeywordsmergesupport" title="Automatic Merge of Version Control Keywords and History (Log)">Automatic Merge ...</a>
</p></dd><dt><span class="term"><span class="emphasis"><em>History merge sorting:</em></span></span></dt><dd><p>
Enable version control history sorting.
</p></dd><dt><span class="term"><span class="emphasis"><em>History entry start sort key order:</em></span></span></dt><dd><p>
Each parentheses used in the regular expression for the history start entry
groups a key that can be used for sorting.
Specify the list of keys (that are numbered in order of occurrence
starting with 1) using ',' as separator (e.g. "4,5,6,1,2,3,7").
If left empty, then no sorting will be done.
See also <a href="merging.html#vcskeywordsmergesupport" title="Automatic Merge of Version Control Keywords and History (Log)">Automatic Merge ...</a>
</p></dd><dt><span class="term"><span class="emphasis"><em>Merge version control history on merge start:</em></span></span></dt><dd><p>
If activated <span class="application">KDiff3</span> runs the automatic history merging using aforementioned options when a merge is started.
</p></dd><dt><span class="term"><span class="emphasis"><em>Max number of history entries:</em></span></span></dt><dd><p>
<span class="application">KDiff3</span> truncates the history list after the specified number of entries. Use -1 to avoid truncation. (Default is -1).
</p></dd><dt><span class="term"><span class="emphasis"><em>Test your regular expressions</em></span></span></dt><dd><p>
This button shows a dialog that allows you to improve and test the regular expressions above.
Just copy the respective data from your files into the example lines. The "Match results"
will immediately show whether the match succeeds or not.
The "Sort key result" will display the key used for history merge sorting.
</p></dd><dt><span class="term"><span class="emphasis"><em>Irrelevant merge command:</em></span></span></dt><dd><p>
Specify a command of your own that should be called when <span class="application">KDiff3</span> detects
that for a three file merge the file from B doesn't contribute any
relevant data that isn't already contained in the file from C.
The command is called with the three filenames as parameters.
Data matched by the "Auto merge regular expression" or in the
history isn't considered relevant.

Changing this option doesn't affect the running program. You have to exit and restart <span class="application">KDiff3</span> so that the language is changed.

</p></dd><dt><span class="term"><span class="emphasis"><em>File Encoding for A/B/C:</em></span></span></dt><dd><p> Adjust the file encoding for input files.

</p></dd><dt><span class="term"><span class="emphasis"><em>File Encoding for Merge Output and Saving:</em></span></span></dt><dd><p> When you have edited a file, then you can adjust which encoding will be used when saving to disk.
</p></dd><dt><span class="term"><span class="emphasis"><em>File Encoding for Preprocessor Files:</em></span></span></dt><dd><p>When you define preprocessors then they might not be able to operate on your codec. (e.g.: Your files are 16-bit-unicode and your preprocessor can only take 8-bit-ascii.) With this option you can define the encoding of preprocessor output.
</p></dd><dt><span class="term"><span class="emphasis"><em>Right To Left Language:</em></span></span></dt><dd><p>Some languages are written right to left. When this option is enabled, <span class="application">KDiff3</span> draws the text from right to left in the diff input windows and in the merge output window. Note that if you start <span class="application">KDiff3</span> with the command line option "--reverse" then all layouting will be done right to left too. (This is a feature provided by Qt.) This documentation was written assuming that "Right To Left Language" or reverse layout are disabled. So some references to "left" or "right" must be replaced by their respective counterpart if you use these options.

Selecting "A vs. B", "A vs. C" or "B vs. C"-overview will show a second overview
column with the required information next to the normal overview.
</p></dd><dt><span class="term"><span class="emphasis"><em>Word wrap diff windows:</em></span></span></dt><dd><p>
Wrap lines when their length would exceed the width of a window.
</p></dd><dt><span class="term"><span class="emphasis"><em>Show Window A/B/C:</em></span></span></dt><dd><p> Sometimes you want to use the space on
the screen better for long lines. Hide the windows that are not important.

Switch between diff windows shown next to each other (A left of B left of C) or above
each other (A above B above C). This should also help for long lines. (In the Windows-menu.)
</p></dd><dt><span class="term"><span class="emphasis"><em>Start a merge quickly:</em></span></span></dt><dd><p>
Sometimes you are viewing the deltas and decide to merge.
<span class="inlinemediaobject"><img src="merge_current.png"></span>
"Merge current file" in the Directory-menu also works if you only compare
two files. A single click starts the merge and uses the filename of the last
input-file as the default output filename. (When this is used to restart
a merge, then the output filename will be preserved.)</p></dd></dl></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="shortcuts"></a>Configuring Keyboard-Shortcuts</h3></div></div></div><p>
