29 ExtUtils::MM_Unix - methods used by ExtUtils::MakeMaker
33 C<require ExtUtils::MM_Unix;>
37 The methods provided by this package are designed to be used in
38 conjunction with ExtUtils::MakeMaker. When MakeMaker writes a
39 Makefile, it creates one or more objects that inherit their methods
40 from a package C<MM>. MM itself doesn't provide any methods, but it
41 ISA ExtUtils::MM_Unix class. The inheritance tree of MM lets operating
42 specific packages take the responsibility for all the methods provided
43 by MM_Unix. We are trying to reduce the number of the necessary
44 overrides by defining rather primitive operations within
47 If you are going to write a platform specific MM package, please try
48 to limit the necessary overrides to primitive methods, and if it is not
49 possible to do so, let's work out how to achieve that gain.
51 If you are overriding any of these methods in your Makefile.PL (in the
52 MY class), please report that to the makemaker mailing list. We are
53 trying to minimize the necessary method overrides and switch to data
54 driven Makefile.PLs wherever possible. In the long run less methods
55 will be overridable via the MY class.
59 The following description of methods is still under
60 development. Please refer to the code for not suitably documented
61 sections and complain loudly to the makemaker mailing list.
63 Not all of the methods below are overridable in a
64 Makefile.PL. Overridable methods are marked as (o). All methods are
65 overridable by a platform specific MM_*.pm file (See
66 L<ExtUtils::MM_VMS>) and L<ExtUtils::MM_OS2>).
68 =head2 Preloaded methods
74 No physical check on the filesystem, but a logical cleanup of a
75 path. On UNIX eliminated successive slashes and successive "/.".
81 $path =~ s|/+|/|g ; # xx////xx -> xx/xx
82 $path =~ s|(/\.)+/|/|g ; # xx/././xx -> xx/xx
83 $path =~ s|^(\./)+|| unless $path eq "./"; # ./xx -> xx
84 $path =~ s|/$|| unless $path eq "/"; # xx/ -> xx
90 Concatenate two or more directory names to form a complete path ending
91 with a directory. But remove the trailing slash from the resulting
92 string, because it doesn't look good, isn't necessary and confuses
93 OS2. Of course, if this is the root directory, don't cut off the
104 # append a slash to each argument unless it has one there
105 $_ .= "/" if $_ eq '' or substr($_,-1) ne "/";
107 $self->canonpath(join('', @args));
112 Concatenate one or more directory names and a filename to form a
113 complete path ending with a filename
120 return $self->canonpath($file) unless @_;
121 my $dir = $self->catdir(@_);
123 $_ .= "/" unless substr($_,length($_)-1,1) eq "/";
125 return $self->canonpath($dir.$file);
130 Returns a string representing of the current directory. "." on UNIX.
140 Returns a string representing of the root directory. "/" on UNIX.
150 Returns a string representing of the parent directory. ".." on UNIX.
