While reading the directories a message-box appears that informs you of
|
|
|
|
|
|
the progress. If you abort the directory scan, then only files that have
|
|
|
|
|
|
been compared until then will be listed.
|
|
|
|
|
|
</p><p>
|
|
|
|
|
|
When the directory scan is complete then <span class="application">KDiff3</span> will show a listbox with
|
|
|
|
|
|
the results left, ...
|
|
|
|
|
|
</p><div class="screenshot"><div xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="mediaobject"><hr><img src="dirbrowser.png"><hr></div></div><p>
|
|
|
|
|
|
... and details about the currently selected item on the right:
|
|
|
|
|
|
</p><div class="screenshot"><div xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="mediaobject"><hr><img src="iteminfo.png"><hr></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="name"></a>The Name Column</h3></div></div></div><p>
|
|
|
|
|
|
Each file and directory that was found during the scan is shown here in
|
|
|
|
|
|
a tree. You can select an item by clicking it with the mouse once.
|
|
|
|
|
|
</p><p>
|
|
|
|
|
|
The directories are collapsed by default. You can expand and collapse
|
|
|
|
|
|
them by clicking on the "+"/"-" or by double-clicking the item or
|
|
|
|
|
|
by using the left/right-arrow-keys. The "Directory"-menu also contains two
|
|
|
|
|
|
actions "Fold all subdirs" and "Unfold all subdirs" with which you can
|
|
|
|
|
|
collapse or expand all directories at once.
|
|
|
|
|
|
</p><p>
|
|
|
|
|
|
If you double-click a file item then the file comparison starts and the
|
|
|
|
|
|
file-diff-window will appear.
|
|
|
|
|
|
</p><p>
|
|
|
|
|
|
The image in the name column reflects the file type in the first
|
|
|
|
|
|
directory ("A"). It can be one of these:
|
|
|
|
|
|
</p><div class="itemizedlist"><ul type="disc"><li><p>Normal file</p></li><li><p>Normal directory (directory-image)</p></li><li><p>Link to a file (file-image with a link arrow)</p></li><li><p>Link to a directory (directory-image with a link arrow)</p></li></ul></div><p>
|
|
|
|
|
|
If the file type is different in the other directories, then this is visible
|
|
|
|
|
|
in the columns A/B/C and in the window that shows the details about the selected
|
|
|
|
|
|
item. Note that for such a case no merge operation can be selected automatically.
|
|
|
|
|
|
When starting the merge, then the user will be informed of problems of that
|
|
|
|
|
|
kind.
|
|
|
|
|
|
</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="coloring"></a>The Columns A/B/C and the Coloring Scheme</h3></div></div></div><p>
|
|
|
|
|
|
As can be seen in the image above the colors red, green, yellow and black
|
|
|
|
|
|
are used in the columns A/B/C.
|
|
|
|
|
|
</p><div class="itemizedlist"><ul type="disc"><li><p>Black: This item doesn't exist in this directory.</p></li><li><p>Green: Newest item.</p></li><li><p>Yellow: Older than green, newer than red.</p></li><li><p>Red: Oldest item.</p></li></ul></div><p>
|
|
|
|
|
|
But for items that were identical in the comparison their color also is
|
|
|
|
|
|
identical even if the age is not.
|
|
|
|
|
|
</p><p>
|
|
|
|
|
|
Directories are considered equal if all items they contain are identical.
|
|
|
|
|
|
Then they also will have the same color. But the age of a directory is not
|
|
|
|
|
|
considered for its color.
|
|
|
|
|
|
</p><p>
|
|
|
|
|
|
The idea for this coloring scheme I came upon in
|
|
|
|
|
|
<a href="http://samba.org/cgi-bin/cvsweb/dirdiff" target="_top">dirdiff</a>. The colors
|
|
|
|
|
|
resemble the colors of a leaf that is green when new, turns yellow later and red
|
|
|
|
|
|
when old.
|
|
|
|
|
|
</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="operation"></a>The Operation Column</h3></div></div></div><p>
|
|
|
|
|
|
After comparing the directories <span class="application">KDiff3</span> also evaluates a proposal for a
|
|
|
|
|
|
merge operation. This is shown in the "Operation" column. You can modify
|
|
|
|
|
|
the operation by clicking on the operation you want to change. A small menu
|
|
|
|
|
|
will popup and allows you to select an operation for that item. (You can also
|
|
|
|
|
|
select the most needed operations via keyboard.
|
|
|
|
|
|
Ctrl+1/2/3/4/Del will select A/B/C/Merge/Delete respectively if available.)
|
|
|
|
|
|
This operation will be executed during the merge. It depends on the item and
|
|
|
|
|
|
on the merge-mode you are in, what operations are available. The merge-mode is one of
|
|
|
|
|
|
</p><div class="itemizedlist"><ul type="disc"><li><p>Three directory-merge ("A" is treated as older base of both).</p></li><li><p>Two directory-merge.</p></li><li><p>Two directory-sync-mode (activate via option "Synchronize Directories").</p></li></ul></div><p>
|
|
|
|
|
|
In three directory merge the operation proposal will be: If for an item ...
|
|
|
|
|
|
</p><div class="itemizedlist"><ul type="disc"><li><p>... all three directories are equal: Copy from C</p></li><li><p>... A and C are equal but B is not: Copy from B (or if B does not
|
|
|
|
|
|
exist, delete the destination if exists)</p></li><li><p>... A and B are equal but C is not: Copy from C (or if C does not
|
|
|
|
|
|
exist, delete the destination if exists)</p></li><li><p>... B and C are equal but A is not: Copy from C (or if C does not
|
|
|
|
|
|
exist, delete the destination if exists)</p></li><li><p>... only A exists: Delete the destination (if exists)</p></li><li><p>... only B exists: Copy from B</p></li><li><p>... only C exists: Copy from C</p></li><li><p>... A, B and C are not equal: Merge</p></li><li><p>... A, B and C don't have the same file type (e.g. A is a directory,
|
|
|
|
|
|
B is a file): "Error: Conflicting File Types". While such items exist the
|
|
|
|
|
|
directory merge cannot start.</p></li></ul></div><p>
|
|
|
|
|
|
In two directory merge the operation proposal will be: If for an item ...
|
|
|
|
|
|
</p><div class="itemizedlist"><ul type="disc"><li><p>... both directories are equal: Copy from B</p></li><li><p>... A exists, but not B: Copy from A</p></li><li><p>... B exists, but not A: Copy from B</p></li><li><p>... A and B exist but are not equal: Merge</p></li><li><p>... A and B don't have the same file type (e.g. A is a directory,
|
|
|
|
|
|
B is a file): "Error: Conflicting File Types". While such items exist the
|
|
|
|
|
|
directory merge cannot start.</p></li></ul></div><p>
|
|
|
|
|
|
Sync-mode is active if only two directories and no explicit destination
|
|
|
|
|
|
were specified and if the option "Synchronize directories" is active. <span class="application">KDiff3</span>
|
|
|
|
|
|
then selects a default operation so that both directories are the same afterwards.
|
|
|
|
|
|
If for an item ...
|
|
|
|
|
|
</p><div class="itemizedlist"><ul type="disc"><li><p>... both directories are equal: Nothing will be done.</p></li><li><p>... A exists, but not B: Copy A to B</p></li><li><p>... B exists, but not A: Copy B to A</p></li><li><p>... A and B exist, but are not equal: Merge and store the result
|
|
|
|
|
|
in both directories. (For the user the visible save-filename is B,
|
|
|
|
|
|
but then <span class="application">KDiff3</span> copies B also to A.)</p></li><li><p>... A and B don't have the same file type (e.g. A is a directory,
|
|
|
|
|
|
B is a file): "Error: Conflicting File Types". While such items exist the
|
|
|
|
|
|
directory merge cannot start.</p></li></ul></div><p>
|
|
|
|
|
|
When two directories are merged and the option "Copy newer instead of merging" is selected,
|
|
|
|
|
|
then <span class="application">KDiff3</span> looks at the dates and proposes to choose the newer file. If the files are not
|
|
|
|
|
|
equal but have equal dates, then the operation will contain
|
|
|
|
|
|
"Error: Dates are equal but files are not." While such items exist the
|
|
|
|
|
|
directory merge cannot start.
|
|
|
|
|
|
</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="status"></a>The Status Column</h3></div></div></div><p>
|
|
|
|
|
|
During the merge one file after the other will be processed. The status
|
|
|
|
|
|
column will show "Done" for items where the merge operation has succeeded,
|
|
|
|
|
|
and other texts if something unexpected happened. When a merge is complete,
|
|
|
|
|
|
then you should make a last check to see if the status for all items is
|
|
|
|
|
|
agreeable.
|
|
|
|
|
|
</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="statisticscolulmns"></a>Statistics Columns</h3></div></div></div><p>
|
|
|
|
|
|
When the file comparison mode "Full Analysis" is enabled in the options, then
|
|
|
|
|
|
<span class="application">KDiff3</span> will show extra columns containing the numbers of unsolved, solved, nonwhite and whitespace
|
|
|
|
|
|
conflicts. (The solved-column will only show when comparing or merging three directories.)
|
|
|
|
|
|
</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="selectingvisiblefiles"></a>Selecting Listed Files</h3></div></div></div><p>
|
|
|
|
|
|
Several options influence which files are listed here. Some are accessible in the
|
|
|
|
|
|
<a href="dirmergeoptions.html" title="Options for Comparing and Merging Directories">settings dialog</a>. The Directory-menu contains the entries:
|
|
|
|
|
|
</p><p><div class="itemizedlist"><ul type="disc"><li><p>"Show Identical Files": Files that have been detected equal in all input directories.</p></li><li><p>"Show Different Files": Files that exist in two or more directories but are not equal.</p></li><li><p>"Show Files only in A": Files that exist only in A, but not in B or C.</p></li><li><p>"Show Files only in B": Files that exist only in B, but not in A or B.</p></li><li><p>"Show Files only in C": Files that exist only in C, but not in A or B.</p></li></ul></div></p><p>
|
|
|
|
|
|
Activate only the "Show"-options for the items you want listed. If for example you only want to list all items that
|
|
|
|
|
|
exist either in A or in B but not in both, you'll have to activate "Show Files only in A" and "Show Files only in B"
|
|
|
|
|
|
and deactivate all others ("Show Identical Files", "Show Different Files", "Show Files only in C").
|
|
|
|
|
|
The list will be updated immediately to reflect the change.
|
|
|
|
|
|
</p><p>
|
|
|
|
|
|
These options also apply for directories with one exception: Disabling "Show Different Files" will not hide
|
|
|
|
|
|
any complete directories. This will work only for files within.
|
|
|
|
|
|
</p><p>
|
|
|
|
|
|
Note that of these only the "Show Identical Files"-option is persistant. The others are enabled when starting <span class="application">KDiff3</span>.
