=head1 NAME

ExtUtils::MM_Unix - methods used by ExtUtils::MakeMaker

=head1 SYNOPSIS

C<require ExtUtils::MM_Unix;>

=head1 DESCRIPTION

The methods provided by this package are designed to be used in
conjunction with ExtUtils::MakeMaker. When MakeMaker writes a
Makefile, it creates one or more objects that inherit their methods
from a package C<MM>. MM itself doesn't provide any methods, but it
ISA ExtUtils::MM_Unix class. The inheritance tree of MM lets operating
specific packages take the responsibility for all the methods provided
by MM_Unix. We are trying to reduce the number of the necessary
overrides by defining rather primitive operations within
ExtUtils::MM_Unix.

If you are going to write a platform specific MM package, please try
to limit the necessary overrides to primitive methods, and if it is not
possible to do so, let's work out how to achieve that gain.

If you are overriding any of these methods in your Makefile.PL (in the
MY class), please report that to the makemaker mailing list. We are
trying to minimize the necessary method overrides and switch to data
driven Makefile.PLs wherever possible. In the long run less methods
will be overridable via the MY class.

=head1 METHODS

The following description of methods is still under
development. Please refer to the code for not suitably documented
sections and complain loudly to the makemaker mailing list.

Not all of the methods below are overridable in a
Makefile.PL. Overridable methods are marked as (o). All methods are
overridable by a platform specific MM_*.pm file (See
L<ExtUtils::MM_VMS>) and L<ExtUtils::MM_OS2>).

=item canonpath

No physical check on the filesystem, but a logical cleanup of a
path. On UNIX eliminated successive slashes and successive "/.".

=cut

sub canonpath {
    my($self,$path) = @_;
    
    # Handle POSIX-style node names beginning with double slash
    my $node = '';
    if ( $^O =~ m/^(?:qnx|nto)$/ && $path =~ s:^(//[^/]+)(/|\z):/:s ) {
      $node = $1;
    }
    $path =~ s|(?<=[^/])/+|/|g ;                   # xx////xx  -> xx/xx
    $path =~ s|(/\.)+/|/|g ;                       # xx/././xx -> xx/xx
    $path =~ s|^(\./)+||s unless $path eq "./";    # ./xx      -> xx
    $path =~ s|(?<=[^/])/\z|| ;                    # xx/       -> xx
    return "$node$path";
}

=item catdir

Concatenate two or more directory names to form a complete path ending
with a directory. But remove the trailing slash from the resulting
string, because it doesn't look good, isn't necessary and confuses
OS2. Of course, if this is the root directory, don't cut off the
trailing slash :-)

=cut

# ';

sub catdir {
    my $self = shift @_;
    my @args = @_;
    for (@args) {
	# append a slash to each argument unless it has one there
	$_ .= "/" if $_ eq '' or substr($_,-1) ne "/";
    }
    $self->canonpath(join('', @args));
}

=item catfile

Concatenate one or more directory names and a filename to form a
complete path ending with a filename

=cut

sub catfile {
    my $self = shift @_;
    my $file = pop @_;
    return $self->canonpath($file) unless @_;
    my $dir = $self->catdir(@_);
    for ($dir) {
	$_ .= "/" unless substr($_,length($_)-1,1) eq "/";
    }
    return $self->canonpath($dir.$file);
}

=item curdir

Returns a string representing of the current directory.  "." on UNIX.

=cut

sub curdir {
    return "." ;
}

=item rootdir

Returns a string representing of the root directory.  "/" on UNIX.

=cut

sub rootdir {
    return "/";
}

=item updir

Returns a string representing of the parent directory.  ".." on UNIX.

=cut

sub updir {
    return "..";

Returns the attribute C<PERM_RW> or the string C<644>.
Used as the string that is passed

relying on the umask provokes hard-to-track bug reports.
When the return value is used by the perl function C<chmod>, it is
interpreted as an octal value.
