=head1 NAME
File::Spec::Cygwin - methods for Cygwin file specs
=head1 SYNOPSIS
require File::Spec::Cygwin; # Done internally by File::Spec if needed
=head1 DESCRIPTION
See L<File::Spec> and L<File::Spec::Unix>. This package overrides the
implementation of these methods, not the semantics.
This module is still in beta. Cygwin-knowledgeable folks are invited
to offer patches and suggestions.

=item canonpath
Any C<\> (backslashes) are converted to C</> (forward slashes),
and then File::Spec::Unix canonpath() is called on the result.
=cut
sub canonpath {
my($self,$path) = @_;
return unless defined $path;
$path =~ s|\\|/|g;
# Handle network path names beginning with double slash
my $node = '';
if ( $path =~ s@^(//[^/]+)(?:/|\z)@/@s ) {
$node = $1;
}
return $node . $self->SUPER::canonpath($path);
}
sub catdir {
my $self = shift;
return unless @_;
# Don't create something that looks like a //network/path
if ($_[0] and ($_[0] eq '/' or $_[0] eq '\\')) {
shift;
return $self->SUPER::catdir('', @_);
}
$self->SUPER::catdir(@_);
}
=pod
=item file_name_is_absolute
True is returned if the file name begins with C<drive_letter:>,
and if not, File::Spec::Unix file_name_is_absolute() is called.
=cut
sub file_name_is_absolute {
my ($self,$file) = @_;
return 1 if $file =~ m{^([a-z]:)?[\\/]}is; # C:/test
return $self->SUPER::file_name_is_absolute($file);
}
=item tmpdir (override)
Returns a string representation of the first existing directory
from the following list:
$ENV{TMPDIR}
/tmp
$ENV{'TMP'}
$ENV{'TEMP'}
C:/temp
Since Perl 5.8.0, if running under taint mode, and if the environment
variables are tainted, they are not used.
=cut
my $tmpdir;
sub tmpdir {
return $tmpdir if defined $tmpdir;
$tmpdir = $_[0]->_tmpdir( $ENV{TMPDIR}, "/tmp", $ENV{'TMP'}, $ENV{'TEMP'}, 'C:/temp' );
}
=item case_tolerant
Override Unix. Cygwin case-tolerance depends on managed mount settings and
as with MsWin32 on GetVolumeInformation() $ouFsFlags == FS_CASE_SENSITIVE,
indicating the case significance when comparing file specifications.
Default: 1
=cut
