=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.
=cut
=pod
=over 4
=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
If running under taint mode, and if the environment
variables are tainted, they are not used.
=cut
sub tmpdir {
my $cached = $_[0]->_cached_tmpdir(qw 'TMPDIR TMP TEMP');
return $cached if defined $cached;
$_[0]->_cache_tmpdir(
$_[0]->_tmpdir(
$ENV{TMPDIR}, "/tmp", $ENV{'TMP'}, $ENV{'TEMP'}, 'C:/temp'
),
qw 'TMPDIR TMP 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
sub case_tolerant {
return 1 unless $^O eq 'cygwin'
and defined &Cygwin::mount_flags;
my $drive = shift;
if (! $drive) {
my @flags = split(/,/, Cygwin::mount_flags('/cygwin'));
my $prefix = pop(@flags);
if (! $prefix || $prefix eq 'cygdrive') {
$drive = '/cygdrive/c';
} elsif ($prefix eq '/') {
$drive = '/c';
} else {
$drive = "$prefix/c";
}
}
my $mntopts = Cygwin::mount_flags($drive);
if ($mntopts and ($mntopts =~ /,managed/)) {
return 0;
}
eval { require Win32API::File; } or return 1;
my $osFsType = "\0"x256;
my $osVolName = "\0"x256;
my $ouFsFlags = 0;
Win32API::File::GetVolumeInformation($drive, $osVolName, 256, [], [], $ouFsFlags, $osFsType, 256 );
if ($ouFsFlags & Win32API::File::FS_CASE_SENSITIVE()) { return 0; }
else { return 1; }
