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.
