28 ExtUtils::MM_Unix - methods used by ExtUtils::MakeMaker
32 C<require ExtUtils::MM_Unix;>
36 The methods provided by this package are designed to be used in
37 conjunction with ExtUtils::MakeMaker. When MakeMaker writes a
38 Makefile, it creates one or more objects that inherit their methods
39 from a package C<MM>. MM itself doesn't provide any methods, but it
40 ISA ExtUtils::MM_Unix class. The inheritance tree of MM lets operating
41 specific packages take the responsibility for all the methods provided
42 by MM_Unix. We are trying to reduce the number of the necessary
43 overrides by defining rather primitive operations within
46 If you are going to write a platform specific MM package, please try
47 to limit the necessary overrides to primitive methods, and if it is not
48 possible to do so, let's work out how to achieve that gain.
50 If you are overriding any of these methods in your Makefile.PL (in the
51 MY class), please report that to the makemaker mailing list. We are
52 trying to minimize the necessary method overrides and switch to data
53 driven Makefile.PLs wherever possible. In the long run less methods
54 will be overridable via the MY class.
58 The following description of methods is still under
59 development. Please refer to the code for not suitably documented
60 sections and complain loudly to the makemaker mailing list.
62 Not all of the methods below are overridable in a
63 Makefile.PL. Overridable methods are marked as (o). All methods are
64 overridable by a platform specific MM_*.pm file (See
65 L<ExtUtils::MM_VMS>) and L<ExtUtils::MM_OS2>).
67 =head2 Preloaded methods
73 No physical check on the filesystem, but a logical cleanup of a
74 path. On UNIX eliminated successive slashes and successive "/.".
80 $path =~ s|/+|/|g ; # xx////xx -> xx/xx
81 $path =~ s|(/\.)+/|/|g ; # xx/././xx -> xx/xx
82 $path =~ s|^(\./)+|| unless $path eq "./"; # ./xx -> xx
83 $path =~ s|/$|| unless $path eq "/"; # xx/ -> xx
89 Concatenate two or more directory names to form a complete path ending
90 with a directory. But remove the trailing slash from the resulting
91 string, because it doesn't look good, isn't necessary and confuses
92 OS2. Of course, if this is the root directory, don't cut off the
103 # append a slash to each argument unless it has one there
104 $_ .= "/" if $_ eq '' or substr($_,-1) ne "/";
106 my $result = join('', @args);
107 # remove a trailing slash unless we are root
108 substr($result,-1) = ""
109 if length($result) > 1 && substr($result,-1) eq "/";
115 Concatenate one or more directory names and a filename to form a
116 complete path ending with a filename
123 return $file unless @_;
124 my $dir = $self->catdir(@_);
126 $_ .= "/" unless substr($_,length($_)-1,1) eq "/";
133 Returns a string representing of the current directory. "." on UNIX.
143 Returns a string representing of the root directory. "/" on UNIX.
153 Returns a string representing of the parent directory. ".." on UNIX.
