package File::Spec::Cygwin; use strict; require File::Spec::Unix; our $VERSION = '3.84'; $VERSION =~ tr/_//d; our @ISA = qw(File::Spec::Unix); =head1 NAME File::Spec::Cygwin - methods for Cygwin file specs =head1 SYNOPSIS require File::Spec::Cygwin; # Done internally by File::Spec if needed =head1 DESCRIPTION See L<File::Spec> and L<File::Spec::Unix>. This package overrides the implementation of these methods, not the semantics. This module is still in beta. Cygwin-knowledgeable folks are invited to offer patches and suggestions. =cut =pod =over 4 =item canonpath Any C<\> (backslashes) are converted to C</> (forward slashes), and then File::Spec::Unix canonpath() is called on the result. =cut sub canonpath { my($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 { local @INC = @INC; pop @INC if $INC[-1] eq '.'; 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; } } =back =head1 COPYRIGHT Copyright (c) 2004,2007 by the Perl 5 Porters.
