DIFFPP(1)                           DIFFPP                           DIFFPP(1)


NAME

       diffpp - pretty-print diff outputs with GNU enscript


SYNOPSIS

       diffpp currentfile < diff-file


DESCRIPTION

       Diffpp converts diff(1)-program's output files to a format suitable to
       be printed with GNU enscript(1).  Program annotates the changes with
       enscript's special escapes so enscript can highlight the modified
       portions of the file.  All changed and added lines are printed with
       gray-background, deleted lines are marked with minus (`-') characters;
       diffpp prints one minus character for each deleted line.


EXAMPLES

       The easiest way to use diffpp is to use it as an input filter for
       enscript.  If an input filter is specified for enscript it is used to
       pre-process the incoming data-stream.  Filtering does not alter any
       header strings or file-timestamps which might be printed on enscript
       headers; only the incoming data is modified.

       enscript -G2re --filter='rcsdiff %s | diffpp %s' *.c *.h
               Print the changes between current source files and their latest
               RCS-versions.

       enscript -G2re --filter='diff %s~ %s | diffpp %s' *.c *.h
               Print changes between source files and the corresponding
               backup-files.
