NAME

       dwfilter - reformat text with dwdiff for further processing

SYNOPSIS

       dwfilter [OPTIONS] OLD FILE NEW FILE POST PROCESSOR [POST PROCESSOR OPTIONS]

DESCRIPTION

       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.
