22 .TH DIFFPP 1 "Jan 29, 1997" "DIFFPP" "DIFFPP"

24 .SH NAME

25 diffpp \- pretty\-print diff outputs with GNU enscript

27 .SH SYNOPSIS

28 .B diffpp \f2currentfile\f1 < \f2diff\-file\f1

30 .SH DESCRIPTION

32 \f3Diffpp\f1 converts \f3diff(1)\f1\-program's output files to a

33 format suitable to be printed with GNU \f3enscript(1)\f1. Program

34 annotates the changes with enscript's special escapes so enscript can

35 highlight the modified portions of the file. All changed and added

36 lines are printed with gray\-background, deleted lines are marked with

37 minus (`\-') characters; \f3diffpp\f1 prints one minus character for

38 each deleted line.

40 .SH EXAMPLES

42 The easiest way to use \f3diffpp\f1 is to use it as an input filter

43 for enscript. If an input filter is specified for enscript it is used

44 to pre\-process the incoming data\-stream. Filtering does not alter any

45 header strings or file\-timestamps which might be printed on enscript

46 headers; only the incoming data is modified.

48 .TP 8

49 \f3enscript \-G2re \-\-filter='rcsdiff %s | diffpp %s' *.c *.h\f1

50 Print the changes between current source files and their latest

51 RCS\-versions.

52 .TP 8

53 \f3enscript \-G2re \-\-filter='diff %s~ %s | diffpp %s' *.c *.h\f1

54 Print changes between source files and the corresponding backup\-files.
