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 por-
       tions 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.
