Overview
dwfilter reformats the text in the old file according to the contents of the new file (or vice versa) and subsequently passes the reformated old file and the new file through a secondary filter. It's main use is to allow visual diff programs such as meld and kdiff3 to be used, even though a text file has been reformated after editing. A further use is to allow the creation of small patches even when the new text has been reformated. dwfilter uses dwdiff for reformatting.
Options
-
-r, --reverse -
Reformat the new file based on the contents of the old file instead of the default where the old file is reformated based on the contents of the new file.
dwfilter accepts the following dwdiff options:
-d delimiters, --delimiters=delimiters
-P, --punctuation
-W whitespace, --white-space=whitespace
-i, --ignore-case
-I, --ignore-formatting
-D option, --diff-option=option
-Cnum, --context=num
-mnum, --match-context=num
--aggregate-changes
--wdiff-output
-A algorithm, --algorithm=algorithm
--profile=name, --no-profile
See the dwdiff manual page for the meaning.
A single dash (-) as a file can be used to denote standard input. Only one file can be read from standard input. To stop dwfilter from interpreting file names that start with a dash as options, one can specify a double dash (--) after which dwfilter will interpret any following arguments as files to read.
