C<mkpath> takes three arguments: - -=over 4 - -=item * - -the name of the path to create, or a reference -to a list of paths to create, - -=item * - -a boolean value, which if TRUE will cause C<mkpath> -to print the name of each directory as it is created -(defaults to FALSE), and - -=item * - -the numeric mode to use when creating the directories -(defaults to 0777), to be modified by the current umask. - -=back - -It returns a list of all directories (including intermediates, determined -using the Unix '/' separator) created. - -If a system error prevents a directory from being created, then the -C<mkpath> function throws a fatal error with C<Carp::croak>. This error -can be trapped with an C<eval> block: - - eval { mkpath($dir) }; - if ($@) { - print "Couldn't create $dir: $@"; - } - -Similarly, the C<rmtree> function provides a convenient way to delete a -subtree from the directory structure, much like the Unix command C<rm -r>. -C<rmtree> takes three arguments: - -=over 4 - -=item * - -the root of the subtree to delete, or a reference to -a list of roots. All of the files and directories -below each root, as well as the roots themselves, -will be deleted. - -=item * - -a boolean value, which if TRUE will cause C<rmtree> to -print a message each time it examines a file, giving the -name of the file, and indicating whether it's using C<rmdir> -or C<unlink> to remove it, or that it's skipping it. -(defaults to FALSE) - -=item * - -a boolean value, which if TRUE will cause C<rmtree> to -skip any files to which you do not have delete access -(if running under VMS) or write access (if running -under another OS). This will change in the future when -a criterion for 'delete permission' under OSs other -than VMS is settled. (defaults to FALSE) - -=back - -It returns the number of files successfully deleted. Symlinks are -simply deleted and not followed. - -B<NOTE:> There are race conditions internal to the implementation of -C<rmtree> making it unsafe to use on directory trees which may be -altered or moved while C<rmtree> is running, and in particular on any -directory trees with any path components or subdirectories potentially -writable by untrusted users. - -Additionally, if the third parameter is not TRUE and C<rmtree> is -interrupted, it may leave files and directories with permissions altered -to allow deletion (and older versions of this module would even set -files and directories to world-read/writable!) - -Note also that the occurrence of errors in C<rmtree> can be determined I<only> -by trapping diagnostic messages using C<$SIG{__WARN__}>; it is not apparent -from the return value. - -=head1 DIAGNOSTICS - -=over 4 - -=item * - -On Windows, if C<mkpath> gives you the warning: B<No such file or -directory>, this may mean that you've exceeded your filesystem's -maximum path length. - -=back - -=head1 AUTHORS - -Tim Bunce <F<Tim.Bunce@ig.co.uk>> and -Charles Bailey <F<bailey@newman.upenn.edu>> - -=cut - -use 5.006; -use Carp; -use File::Basename (); -use Exporter (); -use strict; -use warnings; - -our $VERSION = "1.08"; -our @ISA = qw( Exporter ); -our @EXPORT = qw( mkpath rmtree ); - -my $Is_VMS = $^O eq 'VMS'; -my $Is_MacOS = $^O eq 'MacOS'; - -# These OSes complain if you want to remove a file that you have no -# write permission to: -my $force_writeable = ($^O eq 'os2' || $^O eq 'dos' || $^O eq 'MSWin32' || - $^O eq 'amigaos' || $^O eq 'MacOS' || $^O eq 'epoc'); - -sub mkpath { - my($paths, $verbose, $mode) = @_; - # $paths -- either a path string or ref to list of paths - # $verbose -- optional print "mkdir $path" for each directory created - # $mode -- optional permissions, defaults to 0777 - local($")=$Is_MacOS ?
