31 | =head1 NAME | |
32 | ||
33 | ExtUtils::MM_VMS - methods to override UN*X behaviour in ExtUtils::MakeMaker | |
34 | ||
35 | =head1 SYNOPSIS | |
36 | ||
37 | Do not use this directly. | |
38 | Instead, use ExtUtils::MM and it will figure out which MM_* | |
39 | class to use for you. | |
40 | ||
41 | =head1 DESCRIPTION | |
42 | ||
43 | See ExtUtils::MM_Unix for a documentation of the methods provided | |
44 | there. This package overrides the implementation of these methods, not | |
45 | the semantics. | |

75 | # This isn't really an override. It's just here because ExtUtils::MM_VMS | |
76 | # appears in @MM::ISA before ExtUtils::Liblist::Kid, so if there isn't an ext() | |
77 | # in MM_VMS, then AUTOLOAD is called, and bad things happen. So, we just | |
78 | # mimic inheritance here and hand off to ExtUtils::Liblist::Kid. | |

87 | =head2 Methods | |
88 | ||
89 | Those methods which override default MM_Unix methods are marked | |
90 | "(override)", while methods unique to MM_VMS are marked "(specific)". | |
91 | For overridden methods, documentation is limited to an explanation | |
92 | of why this method overrides the MM_Unix method; see the ExtUtils::MM_Unix | |
93 | documentation for more details. | |

97 | =item guess_name (override) | |
98 | ||
99 | Try to determine name of extension being built. We begin with the name | |
100 | of the current directory. Since VMS filenames are case-insensitive, | |
101 | however, we look for a F<.pm> file whose name matches that of the current | |
102 | directory (presumably the 'main' F<.pm> file for this extension), and try | |
103 | to find a C<package> statement from which to obtain the Mixed::Case | |
104 | package name. | |

283 | =item pasthru (override) | |
284 | ||
285 | VMS has $(MMSQUALIFIERS) which is a listing of all the original command line | |
286 | options. This is used in every invokation of make in the VMS Makefile so | |
287 | PASTHRU should not be necessary. Using PASTHRU tends to blow commands past | |
288 | the 256 character limit. | |

297 | =item pm_to_blib (override) | |
298 | ||
299 | VMS wants a dot in every file so we can't have one called 'pm_to_blib', | |
300 | it becomes 'pm_to_blib.' and MMS/K isn't smart enough to know that when | |
301 | you have a target called 'pm_to_blib' it should look for 'pm_to_blib.'. | |
302 | ||
303 | So in VMS its pm_to_blib.ts. | |

327 | =item perl_script (override) | |
328 | ||
329 | If name passed in doesn't specify a readable file, appends F<.com> or | |
330 | F<.pl> and tries again, since it's customary to have file types on all files | |
331 | under VMS. | |

1863 | Catchall routine to clean up problem MM[SK]/Make macros. Expands macros | |
1864 | in any directory specification, in order to avoid juxtaposing two | |
1865 | VMS-syntax directories when MM[SK] is run. Also expands expressions which | |
1866 | are all macro, so that we can tell how long the expansion is, and avoid | |
1867 | overrunning DCL's command buffer when MM[KS] is running. | |

1869 | fixpath() checks to see whether the result matches the name of a | |
1870 | directory in the current default directory and returns a directory or | |
1871 | file specification accordingly. C<$is_dir> can be set to true to | |
1872 | force fixpath() to consider the path to be a directory or false to force | |
1873 | it to be a file. | |
