Study word level differences / Study character
level differences
If one or both of these options are checked, differences
inside the lines will be studied and displayed.
Using word level differences generaly speeds up the process and
gives reasonably simple results.
Using character level differences will study the text character
by character, producing tighter differences. However the number
of elements being higher the algorithm will be slower and tend
to find more false matches (i.e. producing very short matching
sequences with many changes).
Using both generally produce fast a tight good-looking
result.
Join differences separated by less than N non-blank
characters
This option, when N is not 0, enables the simplification
algorithm. This algorithm studies the characters between two
differences if there are less than N non-blank characters
matching between two differences, the match is considered to be
a false match and is included inside the difference.
Using a large N will tend to melt changes and present a simple
and clear difference but less accurate.
Using a small N (less than 3) will tend to let many small
matches.
