DWFILTER(1)		 reformat text for processing		   DWFILTER(1)

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, --whitespace=whitespace
	      -i, --ignore-case
	      -I, --ignore-formatting
	      -D option, --diff-option=option
	      -Cnum, --context=num
	      -mnum, --match-context=num
	      --aggregate-changes
	      --wdiff-output

       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 inter‐
       preting 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.

BUGS
       If you think you have found a bug, please check that you are using  the
       latest	version	 of  dwdiff  <http://os.ghalkes.nl/dwdiff.html>.  When
       reporting bugs, please include a minimal example that demonstrates  the
       problem.
