This is makepatch, a program to generate a patch file from two files
or directories.

It resembles "diff -c -r -N", but:

  - it is always recursive;
  - it handles 'patchlevel.h' first;
  - it supplies 'Index:' and 'Prereq:' lines;
  - it can use 'manifest' files;
  - it generates shell commands to remove files;
  - it can manipulate manifest files.

#! /bin/sh
# This is a shell archive.  Remove anything before this line, then feed it
# into a shell via "sh file" or similar.  To overwrite existing files,
# type "sh file -c".

XAs distributed, it assumes that perl resides in /usr/local/bin. You

XTo install: edit the Makefile (if needed) and type 'make install'.

X.SH NAME
Xmakepatch \- create patch diffs between two versions of source
X.SH SYNOPSIS
X.B makepatch
X.RI [ options ]
X.I old new
X.PP
X.B makepatch
X\-filelist
X.RI [ options ]
X.I manifest
X
X.SH DESCRIPTION
X.I Makepatch
Xgenerates a set of differences between two files or two sets of files
Xmaintained in two different directories and prints the results to
X\fIstdout\fP.
XThis resulting output is suitable for use by the
X.IR patch (1)
Xprogram to update copies of the target file(s) from the \fIold\fP
Xto the \fInew\fP version.
X.LP
XFeatures of this utility include:
X.na
X.TP 3n
X\-
XRecursive descend through sub-directories.
X.TP 3n
X\-
XGeneration of commands to remove obsolete files.
X.TP 3n
X\-
XAutomatic handling of the \fIpatchlevel.h\fP file first.
X.TP 3n
X\-
XAutomatic inclusion of \fIIndex:\fP and \fIPrereq:\fP lines.
X.TP 3n
X\-
XAbility to utilize specified \fImanifest\fP file(s).
X.ad
X
X.SH ARGUMENTS
X.TP 6
X.I old
XThis is the name of either a single file or else a directory which
Xcontains copies of the older version of the target file(s); in
Xother words, copies of the file(s) \fIprior\fP to any modifications.
X.TP
X.I new
XThis is the name of either a single file or else a directory which
Xcontains copies of the newer version of the target file(s); in
Xother words, copies of the file(s) \fIafter\fP the modifications have
Xbeen made.
XA
X.IR rm (1)
Xcommand will automatically be generated for every
X\fIold\fP file that no longer has a corresponding \fInew\fP version.
X
X.SH "MAKEPATCH OPTIONS"
X.TP 6
X\fB\-diff\fP \fIcmd\fP
XIf specified, \fIcmd\fP is the command to be used to generate the
Xdifferences between the two versions of the files.
XIf not specified, this command defaults to "\fBdiff \-c\fP".
X.TP 6
X\fB\-patchlevel\fP \fIpfile\fP
XIf specified, \fIpfile\fP indicates an alternate file that is to be
Xused in lieu of "\fBpatchlevel.h\fP".
X.TP 6
X\fB\-man\fP[\fBifest\fP] \fImfile\fP
XIf specified, \fImfile\fP indicates the name of the manifest file
Xwhich consists of a list of the files contained in both the \fIold\fP
Xand the \fInew\fP directories.
X.TP 6
X\fB\-oldman\fP[\fBifest\fP] \fIomfile\fP
XIf specified, \fIomfile\fP indicates the name of the manifest file
Xwhich consists of a list of the files contained in the \fIold\fP
Xdirectory.
XThis option is designed to be used in conjunction with the
X\%\fB-newmanifest\fP option.
XNote that the \fIold\fP and \fInew\fP directories must still be
Xindicated.
X.TP 6
X\fB\-newman\fP[\fBifest\fP] \fInmfile\fP
XIf specified, \fInmfile\fP indicates the name of the manifest file
Xwhich consists of a list of the files contained in the \fInew\fP
Xdirectory.
XThis option is designed to be used in conjunction with the
X\%\fB-oldmanifest\fP option.
XNote that the \fIold\fP and \fInew\fP directories must still be
Xindicated.
X.TP 6
X\fB\-follow\fP
XIf specified, symbolic links to directories are traversed as if they
Xwere real directories.
X
X.SH "FILELIST OPTIONS"
X.TP 6
X.BR \- [ file ] list
XThis option instructs
X.I makepatch
Xto read a manifest file, and output the list of files included in
Xthis manifest. This option is useful to turn the contents of a
Xmanifest file into a list of files suitable for other programs.
X.TP 6
X\fB\-man\fP[\fBifest\fP] \fImfile\fP
XIf specified, \fImfile\fP indicates the name of the manifest file to
Xbe used. Alternatively, the name of the manifest file may follow the
Xcommand line options.
X.TP 6
X.B \-prefix
X.I string
XEvery entry in the manifest file is prefixed with
X.I string
Xbefore it is written to
X.IR stdout .
X.TP 6
X.B \-nosort
XRetain the order of filenames from the manifest file.
X
X.SH "GENERAL OPTIONS"
X.TP 6
X.B \-verbose
XThis is the default mode which displays information
Xconcerning \fBmakepatch\fP's activity to \fIstderr\fP.
X.TP 6
X.B \-quiet
XThe opposite of \fB-verbose\fP.
XThis instructs \fImakepatch\fP to suppress the display of
Xactivity information.
X.TP 6
X.B \-help
XThis causes a short help message to be displayed, after which the
Xprogram immediately exits.
X
X.SH "MANIFEST FILES"
XAlthough there is no formal standard for manifest files, the following
Xrules apply:
X.TP 3n
X\-
XIf the second line from the manifest file looks like a separator
Xline (e.g. it is empty, or contains only dashes), it is discarded and
Xso is the first line.
X.TP 3n
X\-
XEmpty lines and lines that start with a
X.B #
Xare ignored.
X.TP 3n
X\-
XIf there are multiple space-separated ``words'' on a line, the
Xfirst word is considered to be the filename.
X
X.SH EXAMPLES
XSuppose you have a directory tree
X.B emacs\-18.58
Xcontaining the sources for GNU Emacs 18.58, and a directory tree
X.B emacs\-18.59
Xcontaining the sources for GNU Emacs 18.59. The following command will
Xgenerate the patch file needed to transform the 18.58 sources into
X18.59:
X
X.in +3n
X.na
Xmakepatch emacs\-18.58 emacs\-18.59 > emacs\-18.58\-18.59.diff
X.in
X.ad
X
XThis is one way to generate and use manifest files:
X
X.in +3n
X.na
X(cd emacs\-18.58; find . \-type f \-print > MANIFEST)
X.br
X(cd emacs\-18.59; find . \-type f \-print > MANIFEST)
X.br
Xmakepatch \e
X.in +3n
X\-oldmanifest emacs\-18.58/MANIFEST \e
X.br
X\-newmanifest emacs\-18.59/MANIFEST \e
X.br
Xemacs\-18.58 emacs\-18.59 > emacs\-18.58\-18.59.diff
X.in -6n
X.ad
X
XThe following example transforms the manifest file into a list of
Xfiles suitable for GNU tar. Note the trailing
X.B /
Xin the prefix string:
X
X.na
X.in +3n
Xmakepatch \-filelist \-prefix emacs\-18.59/ emacs\-18.59/MANIFEST |
X.in +3n
Xgtar \-Zcvf emacs\-18.59.tar.Z \-T \-Op

X################################################################
X#
X# Usage:
X#
X#   makepatch <old-dir> <new-dir
X#
X#     This will compare all files in <new-dir> against the files in
X#     <old-dir>, and generate a bunch of patches to transform every
X#     file in <old-dir> into the corresponding one in <new-dir>.
X#     Files that appear in <new-dir> but not in <old-dir> are created.
X#     For files that appear in <old-dir> but not in <new-dir>
X#     'rm'-commands are generated at the beginning of the patch.
X#
X# Using MANIFEST files:
X#
X#   makepatch -oldmanifest <oldmanifest> -newmanifest <newmanifest> \
X#           <new-dir> <old-dir>
X#
X#     <oldmanifest> and <newmanifest> list the files in <old-dir>
X#     and <new-dir> that are to be examined.
X#     Only the files that are named will be examined.
X#     <oldmanifest> should contain the names of the files relative to
X#     <old-dir> and <newmanifest> should contain the names of the files
X#     relative to <new-dir>.
X#
X#   makepatch -manifest <manifest> <new-dir> <old-dir>
X#
X#     This is a simplified form of the above example.
X#     <manifest> applies to both <old-dir> and <new-dir>.
X#
X#   makepatch -filelist [ -prefix xxx ] manifest
X#
X#     The filenames are extracted from the manifest file,
X#     optionally prefixed, sorted and written to standard output.
X#
X# Examples:
X#
X#   % makepatch -verbose emacs-18.58 emacs-18.59 > emacs-18.58-18.59.diff
X#
X#   % (cd emacs-18.58; find . -type f -print > MANIFEST)
X#   % (cd emacs-18.59; find . -type f -print > MANIFEST)
X#   % makepatch -verbose \
X#         -oldmanifest emacs-18.58/MANIFEST \
X#         -newmanifest emacs-18.59/MANIFEST \
X#         emacs-18.58 emacs-18.59 > emacs-18.58-18.59.diff
X#
X#   % makepatch -filelist -prefix emacs-18.59/ emacs-18.59/MANIFEST |
X#    gtar -zcvf emacs-18.59.tar.Z -T -
