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.
