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 en-
script. 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.
