It is known to work with +.IR mgdiff , +.IR tkdiff , +and +.IR xdiff . +.LP +Unless I am mistaken, most of the GUI difference viewers (except for emacs) +do not have built-in support for recursing down two directories, but +.I diff +does. Based on +.IR diff 's +output, +.I rmgdiff +decides when to invoke the graphical difference viewer. +.LP +In addition, +.I rmgdiff +also collates +.IR diff 's +output. As soon as a new difference is encountered in a text file, +.I rmgdiff +will print to standard output the name of the file that both directories have +in common. It will then start the GUI and block until the user exits. +As more text files with differences are found, the GUI will be started up +again. +.LP +In the interim, +.I rmgdiff +will keep track of differences in binary (non-text) files. It organizes +the binary files as executables, shared libraries, static libraries, object +files, and other. Only after all the text files have been displayed will +.I rmgdiff +report the binary differences. +.LP +It also keeps track of files and directories that +.I diff +reports as being only in one directory or another. +.I rmgdiff +organizes these entries by directory. Thus, files in one directory +will be reported in one block, and files that are in the other directory +will be reported in a different block. +.LP +In addition to printing the name of the files that are different, +.I rmgdiff +defaults to printing the relevant portion of the output from the +.I file +command. This has the unfortunate side-effect of slowing things down; +however, I find this information to be invaluable. If you're just looking +for a fast way to collate +.IR diff 's +output, try piping it into +.I sort +instead. + +.SH COMMAND LINE OPTIONS +.TP 8 +.B \-b +Sets the basic reporting mode. In basic mode, rmgdiff reports only +file names. It does not report the file types involved. +.TP 8 +.B \-c +By default, files relating to +.I CVS +are ignored by +.IR rmgdiff . +If you want to include CVS files, use this option. +.TP 8 +.B \-d +Sets +.I rmgdiff +to print way too much debugging information. +.TP 8 +\fB\-g\fP \fIgui\fP +Tells +.I rmgdiff +which gui you would like to use for viewing differences. By default, +.I mgdiff +is used. You can also set $RMGDIFF_GUI in your environment, but it can +be overridden with this option. +.TP 8 +.B \-n +.I rmgdiff +will not invoke the gui. This is useful, if you only want to view the +collated output. + +.SH AUTHOR +Paul Serice (paul@serice.net) --- debian/mgdiff.substvars +++ debian/mgdiff.substvars @@ -0,0 +1 @@ +shlibs:Depends=lesstif2, libc6 (>= 2.3.5-1), libice6 | xlibs (>> 4.1.0), libsm6 | xlibs (>> 4.1.0), libx11-6 | xlibs (>> 4.1.0), libxext6 | xlibs (>> 4.1.0), libxt6 | xlibs (>> 4.1.0) --- debian/copyright +++ debian/copyright @@ -0,0 +1,42 @@ +This package was debianized by Paul Serice <ugs@debian.org> on +Tue, 25 Aug 1998 23:05:16 -0500. + +It was downloaded from ftp://ftp.x.org/contrib/applications/mgdiff.tar.gz . + +Please note that rmgdiff is not a part of the mgdiff distribution.

It then takes diff's +# output and calls mgdiff once for each pair of text +# files that differ. It prints out a message to this +# effect. It then prints out a list of binary files +# that have differences followed by a list of files +# that appear only in the first directory followed by a +# list of files that appear only in the second +# directory. +# +# It expects you to pass in <dir1> and <dir2> on the +# command line using awk's "-v" option. You should +# find the shell script I use to call this file near +# where you found this file. +# +# -- Paul Serice +# + +# +# Changes: +# +# v1.8.1 Minor clean up. +# +# v1.8.0 Testing revealed problems handling white space. +# +# v1.7 Fixed a problem with the regular expression that +# escapes meta-characters in the escape_dir() function. +# Now, both gawk and mawk should be able to interpret this +# script. +# +# v1.6 Changed the "rmgdiff" shell script wrapper so that this +# awk script does not have to be in the same directory. +# You can now place both "rmgdiff" and "rmgdiff.awk" in +# any directory and place a symbolic link in a "bin" +# directory that points to the "rmgdiff" shell script. +# The shell script will then follow the symbolic links +# in order to find the "rmgdiff.awk" script. One way to +# set this up is as follows: +# +# /usr/local/lib/rmgdiff/rmgdiff +# /usr/local/lib/rmgdiff/rmgdiff.awk +# /usr/local/bin/rmgdiff -> ../lib/rmgdiff/rmgdiff +# +# v1.5 I've said it before, and here I go again. This time +# it's fixed. v1.4 introduced a new bug related to the same +# section of code that v1.3 and v1.4 was trying to fix. +# This new bug manifested itself when a subdirectory was +# only in one directory and had a minimum depth of at least +# 2. Everything that was originally a bug and everything I +# subsequently broke now appears to work. +# v1.4 Was finally able to reproduce the bug that was causing +# reported directories to appear to have been split +# incorrectly. Problem solved. +# v1.3 Forgot to escape the accidental meta-characters in the +# directory names. Also, I am explicitly putting both the +# "rmgdiff" shell script and this "rmgdiff.awk" awk script +# in the public domain. (It has always been in the public +# domain. This just makes it official. Use at your own +# risk.) +# v1.2 Changed the way the "rmgdiff" shell script initialized the +# RMGDIFF_GUI variable. +# v1.1 Fixed bug in "/^Binary file /" rule that used "$4" and "$6" +# instead of "$3" and "$5". +# v1.0 Initial release +# + +# +# trim_dir(dir) -- A user can enter a directory such as "dir", "dir/", +# "dir//", etc. trim_dirr() will reduce all of these +# to "dir" by removing all trailing slashes. +# +function trim_dir( dir , pos ) { + if( !dir ) + return ""; + + pos = length(dir); + while( pos > 0 ) + { + if( substr(dir, pos, 1) != "/" ) + break; + pos--; + } + + # If you made it back to the beginning, then "dir" was all slashes + # which is a synonym for the root dir. + if( pos <= 0 ) + return "/"; + else + return substr(dir, 1, pos); +} + + +# +# escape_dir(dir) -- Escape the characters in the directory name that +# are coincidentally meta characters. +# +function escape_dir(dir) { + gsub(/[[\]{}()^$. +|*?]/, "\\\\&", dir); + return dir; +} + + +# +# relative_path(full_path, upper_dir) +# +# This function strips off the upper most directory.
