The <span class="application">KDiff3</span>-preferences (menu "Settings"->"Configure <span class="application">KDiff3</span>") has
|
|
|
a section called "Directory Merge" with these options:
|
|
|
</p><div class="variablelist"><dl><dt><span class="term"><span class="emphasis"><em>Recursive Directories:</em></span></span></dt><dd><p> Select whether to search directories
|
|
|
recursively.</p></dd><dt><span class="term"><span class="emphasis"><em>File Pattern(s):</em></span></span></dt><dd><p> Only files that match any pattern here will
|
|
|
be put in the tree. More than one pattern may be specified here by using
|
|
|
the semicolon ";" as separator. Valid wildcards: '*' and '?'. (e.g. "*.cpp;*.h").
|
|
|
Default is "*". This pattern is not used on directories.</p></dd><dt><span class="term"><span class="emphasis"><em>File Anti-Pattern(s):</em></span></span></dt><dd><p> Files that match this pattern
|
|
|
will be excluded from the tree. More than one pattern may be specified here
|
|
|
via using the semicolon ";" as separator. Valid wildcards: '*' and '?'. Default
|
|
|
is "*.orig;*.o;*.obj".</p></dd><dt><span class="term"><span class="emphasis"><em>Directory Anti-Pattern(s):</em></span></span></dt><dd><p> Directories that match this pattern
|
|
|
will be excluded from the tree. More than one pattern may be specified here
|
|
|
via using the semicolon ";" as separator. Valid wildcards: '*' and '?'. Default
|
|
|
is "CVS;deps;.svn".</p></dd><dt><span class="term"><span class="emphasis"><em>Use CVS-Ignore:</em></span></span></dt><dd><p>
|
|
|
Ignore files and directories that would also be ignored by CVS.
|
|
|
Many automatically generated files are ignored by CVS.
|
|
|
The big advantage is that this can be directory specific via a local ".cvsignore"-file.
|
|
|
(See <a href="info:/cvs/cvsignore" target="_top">info:/cvs/cvsignore</a>.)</p></dd><dt><span class="term"><span class="emphasis"><em>Find Hidden Files and Directories:</em></span></span></dt><dd><p> On some file systems files
|
|
|
have an "Hidden"-attribute. On other systems a filename starting with a dot
|
|
|
"." causes it to be hidden. This option allows you to decide whether to
|
|
|
include these files in the tree or not. Default is on.</p></dd><dt><span class="term"><span class="emphasis"><em>Follow File Links:</em></span></span></dt><dd><p> For links to files: When disabled, then
|
|
|
the symbolic links are compared. When enabled, then the files behind the
|
|
|
links are compared. Default is off.</p></dd><dt><span class="term"><span class="emphasis"><em>Follow Directory Links:</em></span></span></dt><dd><p> For links to directories: When disabled,
|
|
|
then the symbolic links will be compared. When enabled then the link will
|
|
|
be treated like a directory and it will be scanned recursively. (Note that
|
|
|
the program doesn't check if the link is "recursive". So for example a directory
|
|
|
that contains a link to the directory would cause an infinite loop, and after
|
|
|
some time when the stack overflows or all memory is used up, crash the program.)
|
|
|
Default is off.</p></dd><dt><span class="term"><span class="emphasis"><em>Case Sensitive Filename Comparison:</em></span></span></dt><dd><p>
|
|
|
Default is false on Windows, true for other operating systems.</p></dd><dt><span class="term"><span class="emphasis"><em>File Comparison Mode:</em></span></span></dt><dd><p>
|
|
|
<div class="variablelist"><dl><dt><span class="term"><span class="emphasis"><em>Binary Comparison:</em></span></span></dt><dd><p>
|
|
|
This is the default file comparison mode.
|
|
|
</p></dd><dt><span class="term"><span class="emphasis"><em>Full Analysis:</em></span></span></dt><dd><p>
|
|
|
Do a full analysis of each file and show the statistics information columns.
|
|
|
(Number of solved, unsolved, nonwhite and white conflicts.)
|
|
|
The full analysis is slower than a simple binary analysis, and much
|
|
|
slower when used on files that don't contain text.
|
|
|
(Specify the appropriate file-antipatterns.)
|
|
|
</p></dd><dt><span class="term"><span class="emphasis"><em>Trust the modification date:</em></span></span></dt><dd><p> If you compare big directories
|
|
|
over a slow network, it might be faster to compare the modification dates
|
|
|
and file length alone. But this speed improvement comes with the price of
|
|
|
a little uncertainty. Use this option with care. Default is off.</p></dd><dt><span class="term"><span class="emphasis"><em>Trust the size:</em></span></span></dt><dd><p>
|
|
|
Similar to trusting the modification date. No real comparison happens. Two
|
|
|
files are considered equal if their file-sizes are equal. This is useful
|
|
|
when the file-copy operation didn't preserve the modification date.
|
|
|
Use this option with care. Default is off.</p></dd></dl></div></p></dd><dt><span class="term"><span class="emphasis"><em>Synchronize Directories:</em></span></span></dt><dd><p> Activates "Sync-Mode" when two directories
|
|
|
are compared and no explicit destination directory was specified. In this
|
|
|
mode the proposed operations will be chosen so that both source directories
|
|
|
are equal afterwards. Also the merge result will be written to both directories.
|
|
|
Default is off.</p></dd><dt><span class="term"><span class="emphasis"><em>Copy newer instead of merging:</em></span></span></dt><dd><p> Instead of merging the proposed
|
|
|
operation will copy the newer source if changes happened. (Considered unsafe,
|
|
|
because it implies that you know, that the other file hasn't been edited
|
|
|
too. Check to make sure in every case.) Default is off.</p></dd><dt><span class="term"><span class="emphasis"><em>Backup files:</em></span></span></dt><dd><p> If a file or complete directory is replaced
|
|
|
by another or is deleted then the original version will be renamed with an
|
|
|
".orig" extension. If an old backup file with ".orig" extension already exists
|
|
|
then this will be deleted without backup. This also affects the normal merging
|
|
|
of single files, not only in directory-merge mode. Default is on.</p></dd></dl></div></div><div style="background-color: #white; color: black; margin-top: 20px; margin-left: 20px; margin-right: 20px;"><div style="position: absolute; left: 20px;"><a accesskey="p" href="dothemerge.html">Prev</a></div><div style="position: absolute; right: 20px;"><a accesskey="n" href="other.html">Next</a></div><div align="center"><a accesskey="h" href="index.html">Home</a></div></div><div style="background-color: #white; color: black; margin-left: 20px; margin-right: 20px;"><div class="navLeft">Doing A Directory Merge </div><div class="navRight"> Other Functions in Directory Merge Window</div><div class="navCenter"><a accesskey="u" href="dirmerge.html">Up</a></div></div><br><br><div class="bannerBottom" style="background-image: url(help:/common/bottom-middle.png); background-repeat: x-repeat; width: 100%; height: 100px; bottom:0px;"><div class="BannerBottomRight"><img src="help:/common/bottom-right.png" style="margin: 0px" alt=""></div><div class="bannerBottomLeft"><img src="help:/common/bottom-left.png" style="margin: 0px;" alt=""></div><div id="comments" style="position:relative; top: 5px; left: 1em; height:85px; width: 50%; color: #cfe1f6"><p>Would you like to make a comment or contribute an update to this page?<br>
