dwdiff is a diff program that operates at the word level instead of the line level. It is different from wdiff in that it allows the user to specify what should be considered whitespace, and in that it takes an optional list of characters that should be considered delimiters.
Delimiters are single characters that are treated as if they are words, even when there is no whitespace separating them from preceding words or delimiters.
dwdiff is mostly commandline compatible with wdiff. Only the –autopager, –terminal and –avoid-wraps options are not supported.
The default output from dwdiff is the new text, with the deleted and inserted parts annotated with markers. Command line options are available to change both what is printed, and the markers.
