For instance let's say that you want -# # to append '/subpath': -# filename="$filename/subpath" -# # finally switch back to the original notation -# AX_NORMALIZE_PATH([filename], ["$old_filename"]) -# # now $filename equals to 'A:\FOO\BAR\subpath' -# -# One good reason to make all path processing with the unix convention is -# that backslashes have a special meaning in many cases. For instance -# -# expr 'A:\FOO' : 'A:\Foo' -# -# will return 0 because the second argument is a regex in which -# backslashes have to be backslashed. In other words, to have the two -# strings to match you should write this instead: -# -# expr 'A:\Foo' : 'A:\\Foo' -# -# Such behavior makes DOS filenames extremely unpleasant to work with. So -# temporary turn your paths to the Unix notation, and revert them to the -# original notation after the processing. See the macro -# AX_COMPUTE_RELATIVE_PATHS for a concrete example of this. -# -# REFERENCE_STRING defaults to $VARIABLE, this means that slashes will be -# converted to backslashes if $VARIABLE already contains some backslashes -# (see $thirddir below). -# -# firstdir='/usr/local//share' -# seconddir='C:\Program Files\\' -# thirddir='C:\home/usr/' -# AX_NORMALIZE_PATH([firstdir]) -# AX_NORMALIZE_PATH([seconddir]) -# AX_NORMALIZE_PATH([thirddir]) -# # $firstdir = '/usr/local/share' -# # $seconddir = 'C:\Program Files' -# # $thirddir = 'C:\home\usr' -# -# LICENSE -# -# Copyright (c) 2008 Alexandre Duret-Lutz <adl@gnu.org> -# -# This program is free software; you can redistribute it and/or modify it -# under the terms of the GNU General Public License as published by the -# Free Software Foundation; either version 2 of the License, or (at your -# option) any later version. -# -# This program is distributed in the hope that it will be useful, but -# WITHOUT ANY WARRANTY; without even the implied warranty of -# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
