Tools named "KDiff" and "KDiff2" (now called "Kompare") already exist. Also "KDiff3" should suggest

that it can merge like the "diff3"-tool in the Diff-Tool collection.

I'm using GPL programs for a very long time now and learned very much

You compiled from source but you probably didn't specify the correct KDE-prefix
|
|
|
with configure. By default configure wants to install in /usr/local but then KDE can't
|
|
|
find the user-interface ressource file (i.e. kdiff3ui.rc). The README-file contains
|
|
|
more information about the correct prefix.

Lines where only the amount of white space characters is different
|
|
|
are treated as "equal" at first, while just one different non-white character
|
|
|
causes the lines to be "different". If similar lines appear next to each
|
|
|
other, this actually is coincidence but this fortunately is often the case.

For each equal or different section the editor in the merge result
|
|
|
window remembers where it begins or ends. This is needed so that conflicts
|
|
|
can be solved manually by simply selecting the source button (A, B or C).
|
|
|
This information is lost while saving as text and it is too much effort to
|
|
|
create a special file format that supports saving and restoring all necessary
|
|
|
information.

This was too much effort until now. You can always
|
|
|
restore a version from one source (A, B or C) by clicking the respective
|
|
|
button. For big editing the use of another editor is recommended anyway.

For each equal or different section the editor in the merge result
|
|
|
window remembers where it begins or ends. "<No src line>" means
|
|
|
that there is nothing left in a section, not even a new line character.
|
|
|
This can happen either while merging automatically or by editing. This is
|
|
|
no problem, since this hint won't appear in the saved file. If you want
|
|
|
the orignal source back just select the section (click on the left summary
|
|
|
column) and then click the source button with the needed contents (A/B or
|
|
|
C).

<span class="application">KDiff3</span> already uses many colors for difference highlighting. More

highlighting would be confusing. Use another editor for this.

Although <span class="application">KDiff3</span> will analyse any kind of file the result will probably
|
|
|
not be very satisfactory for you.
|
|
|
</p><p>
|
|
|
<span class="application">KDiff3</span> was made to compare pure text files. OpenOffice, Word, Excel etc.
|
|
|
store much more information in the files (about fonts, pictures, pages,
|
|
|
colors etc.) which <span class="application">KDiff3</span> doesn't know about. So <span class="application">KDiff3</span> will
|
|
|
show you the contents of the file interpreted as pure text, but
|
|
|
this might be unreadable or at least it will look very odd.
|
|
|
</p><p>
|
|
|
Since most programs nowadays store their contents in XML-format, you might
|
|
|
be able to read it as pure text. So if the change was only small,
|
|
|
<span class="application">KDiff3</span> still might help you.
|
|
|
</p><p>
|
|
|
The best solution if you only want to compare the text (without embedded
|
|
|
objects like pictures) is to use "Select All" and "Copy" in your program
|
|
|
to copy the interesting text to the clipoard and then in <span class="application">KDiff3</span> paste the
|
|
|
text into either diff input window.

There are now several <a href="dirmergevisible.html#selectingvisiblefiles" title="Selecting Listed Files">"Show"-options</a> in the directory menu.

Disabling "Show identical files" will achieve what enabling "List only deltas" used to do.
