30361541 | 26 | ExtUtils::MM_Any - Platform-agnostic MM methods |
f6d6199c MS |

28 | =head1 SYNOPSIS | |
29 | ||
30 | FOR INTERNAL USE ONLY! | |
31 | ||
32 | package ExtUtils::MM_SomeOS; | |
33 | ||
34 | # Temporarily, you have to subclass both. Put MM_Any first. | |

38 | ||
39 | =head1 DESCRIPTION | |
40 | ||
41 | B<FOR INTERNAL USE ONLY!> | |
42 | ||
43 | ExtUtils::MM_Any is a superclass for the ExtUtils::MM_* set of | |
44 | modules. It contains methods which are either inherently | |
45 | cross-platform or are written in a cross-platform manner. | |
46 | ||
47 | Subclass off of ExtUtils::MM_Any I<and> ExtUtils::MM_Unix. This is a | |
48 | temporary solution. | |
49 | ||
50 | B<THIS MAY BE TEMPORARY!> | |

64 | =head3 os_flavor I<Abstract> |
65 | ||
66 | my @os_flavor = $mm->os_flavor; | |
67 | ||
68 | @os_flavor is the style of operating system this is, usually | |
69 | corresponding to the MM_*.pm file we're using. | |
70 | ||
71 | The first element of @os_flavor is the major family (ie. Unix, | |
72 | Windows, VMS, OS/2, etc...) and the rest are sub families. | |
73 | ||
74 | Some examples: | |
75 | ||
76 | Cygwin98 ('Unix', 'Cygwin', 'Cygwin9x') | |
77 | Windows NT ('Win32', 'WinNT') | |
78 | Win98 ('Win32', 'Win9x') | |
79 | Linux ('Unix', 'Linux') | |
80 | MacOS X ('Unix', 'Darwin', 'MacOS', 'MacOS X') | |
81 | OS/2 ('OS/2') | |
82 | ||
83 | This is used to write code for styles of operating system. | |
84 | See os_flavor_is() for use. | |

90 | my $is_this_flavor = $mm->os_flavor_is(@one_of_these_flavors); | |
dedf98bc MS |
91 | |
92 | Checks to see if the current operating system is one of the given flavors. | |
93 | ||
94 | This is useful for code like: | |
95 | ||
96 | if( $mm->os_flavor_is('Unix') ) { | |
97 | $out = `foo 2>&1`; | |
98 | } | |
99 | else { | |
100 | $out = `foo`; | |
101 | } | |

479d2113 MS |
113 | |
114 | my @cmds = $MM->split_command($cmd, @args); | |
115 | ||
116 | Most OS have a maximum command length they can execute at once. Large | |
117 | modules can easily generate commands well past that limit. Its | |
118 | necessary to split long commands up into a series of shorter commands. | |
119 | ||
7292dc67 | 120 | C<split_command> will return a series of @cmds each processing part of |
479d2113 MS |
121 | the args. Collectively they will process all the arguments. Each |
122 | individual line in @cmds will not be longer than the | |
123 | $self->max_exec_len being careful to take into account macro expansion. | |
124 | ||
125 | $cmd should include any switches and repeated initial arguments. | |
126 | ||
127 | If no @args are given, no @cmds will be returned. | |
128 | ||
129 | Pairs of arguments will always be preserved in a single command, this | |
130 | is a heuristic for things like pm_to_blib and pod2man which work on | |
131 | pairs of arguments. This makes things like this safe: | |
132 | ||
133 | $self->split_command($cmd, %pod2man); | |

479d2113 | 223 | |
7292dc67 RGS |
224 | Takes an array of items and turns them into a well-formatted list of |
225 | arguments. In most cases this is simply something like: | |
479d2113 | 226 | |
7292dc67 RGS |
227 | FOO \ |
228 | BAR \ | |
229 | BAZ | |

479d2113 | 240 | |
7292dc67 | 241 | my $subdir_cmd = $MM->cd($subdir, @cmds); |
479d2113 | 242 | |
7292dc67 RGS |
243 | This will generate a make fragment which runs the @cmds in the given |
244 | $dir. The rough equivalent to this, except cross platform. | |
479d2113 | 245 | |
7292dc67 | 246 | cd $subdir && $cmd |
479d2113 | 247 | |
7292dc67 RGS |
248 | Currently $dir can only go down one level. "foo" is fine. "foo/bar" is |
249 | not. "../foo" is right out. | |
479d2113 | 250 | |
7292dc67 RGS |
251 | The resulting $subdir_cmd has no leading tab nor trailing newline. This |
252 | makes it easier to embed in a make string. For example. | |
479d2113 | 253 | |
7292dc67 RGS |
254 | my $make = sprintf <<'CODE', $subdir_cmd; |
255 | foo : | |
256 | $(ECHO) what | |
257 | %s | |
258 | $(ECHO) mouche | |

7292dc67 | 262 | =head3 oneliner I<Abstract> |
479d2113 | 263 | |
7292dc67 RGS |
264 | my $oneliner = $MM->oneliner($perl_code); |
265 | my $oneliner = $MM->oneliner($perl_code, \@switches); | |
479d2113 | 266 | |
7292dc67 RGS |
267 | This will generate a perl one-liner safe for the particular platform |
268 | you're on based on the given $perl_code and @switches (a -e is | |
269 | assumed) suitable for using in a make target. It will use the proper | |
270 | shell quoting and escapes. | |
479d2113 | 271 | |
7292dc67 | 272 | $(PERLRUN) will be used as perl. |
479d2113 | 273 | |
7292dc67 RGS |
274 | Any newlines in $perl_code will be escaped. Leading and trailing |
275 | newlines will be stripped. Makes this idiom much easier: | |
479d2113 | 276 | |
7292dc67 RGS |
277 | my $code = $MM->oneliner(<<'CODE', [...switches...]); |
278 | some code here | |
279 | another line here | |
280 | CODE | |
479d2113 | 281 | |
7292dc67 | 282 | Usage might be something like: |
479d2113 | 283 | |
7292dc67 RGS |
284 | # an echo emulation |
285 | $oneliner = $MM->oneliner('print "Foo\n"'); | |
286 | $make = '$oneliner > somefile'; | |
479d2113 | 287 | |
7292dc67 RGS |
288 | All dollar signs must be doubled in the $perl_code if you expect them |
289 | to be interpreted normally, otherwise it will be considered a make | |
290 | macro. Also remember to quote make macros else it might be used as a | |
291 | bareword. For example: | |
479d2113 | 292 | |
7292dc67 RGS |
293 | # Assign the value of the $(VERSION_FROM) make macro to $vf. |
294 | $oneliner = $MM->oneliner('$$vf = "$(VERSION_FROM)"'); | |
f6d6199c | 295 | |
7292dc67 RGS |
296 | Its currently very simple and may be expanded sometime in the figure |
297 | to include more flexible code and switches. | |

7292dc67 | 302 | my $safe_text = $MM->quote_literal($text); |
f6d6199c | 303 | |
7292dc67 | 304 | This will quote $text so it is interpreted literally in the shell. |
f6d6199c | 305 | |
7292dc67 RGS |
306 | For example, on Unix this would escape any single-quotes in $text and |
307 | put single-quotes around the whole thing. | |

1457 | Initializes the DIRFILESEP macro which is the seperator between the | |
1458 | directory and filename in a filepath. ie. / on Unix, \ on Win32 and | |
1459 | nothing on VMS. | |
1460 | ||
1461 | For example: | |
1462 | ||
1463 | # instead of $(INST_ARCHAUTODIR)/extralibs.ld | |
1464 | $(INST_ARCHAUTODIR)$(DIRFILESEP)extralibs.ld | |
1465 | ||
1466 | Something of a hack but it prevents a lot of code duplication between | |
1467 | MM_* variants. | |
1468 | ||
1469 | Do not use this as a seperator between directories. Some operating | |
1470 | systems use different seperators between subdirectories as between | |
1471 | directories and filenames (for example: VOLUME:[dir1.dir2]file on VMS). | |

1483 | linker command line I<after> the external libraries to be linked to | |
1484 | dynamic extensions. This may be needed if the linker is one-pass, and | |
1485 | Perl includes some overrides for C RTL functions, such as malloc(). | |

1488 | to be exported. | |
1489 | ||
