When MakeMaker writes a Makefile, it creates one or more objects that inherit their methods from a package C. 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) and L). =head2 Preloaded methods =over 2 =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) = @_; my $node = ''; if ( $^O eq 'qnx' && $path =~ s|^(//\d+)/|/| ) { $node = $1; } $path =~ s|/+|/|g ; # xx////xx -> xx/xx $path =~ s|(/\.)+/|/|g ; # xx/././xx -> xx/xx $path =~ s|^(\./)+|| unless $path eq "./"; # ./xx -> xx $path =~ s|/$|| unless $path eq "/"; # xx/ -> xx "$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.
