24 | ||
25 | ExtUtils::MM_Any - Platform-agnostic MM methods | |
26 | ||
27 | =head1 SYNOPSIS | |
28 | ||
29 | FOR INTERNAL USE ONLY! | |
30 | ||
31 | package ExtUtils::MM_SomeOS; | |
32 | ||
33 | # Temporarily, you have to subclass both. Put MM_Any first. | |

38 | =head1 DESCRIPTION | |
39 | ||
40 | B<FOR INTERNAL USE ONLY!> | |
41 | ||
42 | ExtUtils::MM_Any is a superclass for the ExtUtils::MM_* set of | |
43 | modules. It contains methods which are either inherently | |
44 | cross-platform or are written in a cross-platform manner. | |
45 | ||
46 | Subclass off of ExtUtils::MM_Any I<and> ExtUtils::MM_Unix. This is a | |
47 | temporary solution. | |
48 | ||
49 | B<THIS MAY BE TEMPORARY!> | |
50 | ||
51 | ||
52 | =head1 METHODS | |
53 | ||
54 | Any methods marked I<Abstract> must be implemented by subclasses. | |
55 | ||
56 | ||
57 | =head2 Cross-platform helper methods | |
58 | ||
59 | These are methods which help writing cross-platform code. | |

63 | =head3 os_flavor I<Abstract> | |
64 | ||
65 | my @os_flavor = $mm->os_flavor; | |
66 | ||
67 | @os_flavor is the style of operating system this is, usually | |
68 | corresponding to the MM_*.pm file we're using. | |
69 | ||
70 | The first element of @os_flavor is the major family (ie. Unix, | |
71 | Windows, VMS, OS/2, etc...) and the rest are sub families. | |
72 | ||
73 | Some examples: | |
74 | ||
75 | Cygwin98 ('Unix', 'Cygwin', 'Cygwin9x') | |
76 | Windows NT ('Win32', 'WinNT') | |
77 | Win98 ('Win32', 'Win9x') | |
78 | Linux ('Unix', 'Linux') | |
79 | MacOS X ('Unix', 'Darwin', 'MacOS', 'MacOS X') | |
80 | OS/2 ('OS/2') | |
81 | ||
82 | This is used to write code for styles of operating system. | |
83 | See os_flavor_is() for use. | |
84 | ||
85 | ||
86 | =head3 os_flavor_is | |
87 | ||
88 | my $is_this_flavor = $mm->os_flavor_is($this_flavor); | |
89 | my $is_this_flavor = $mm->os_flavor_is(@one_of_these_flavors); | |
90 | ||
91 | Checks to see if the current operating system is one of the given flavors. | |
92 | ||
93 | This is useful for code like: | |
94 | ||
95 | if( $mm->os_flavor_is('Unix') ) { | |
96 | $out = `foo 2>&1`; | |
97 | } | |
98 | else { | |
99 | $out = `foo`; | |
100 | } | |
101 | ||

103 | ||
104 | sub os_flavor_is { | |
105 | my $self = shift; | |
106 | my %flavors = map { ($_ => 1) } $self->os_flavor; | |
107 | return (grep { $flavors{$_} } @_) ? 1 : 0; | |
108 | } | |
109 | ||
110 | ||
111 | =head3 split_command | |
112 | ||
113 | my @cmds = $MM->split_command($cmd, @args); | |
114 | ||
115 | Most OS have a maximum command length they can execute at once. Large | |
116 | modules can easily generate commands well past that limit. Its | |
117 | necessary to split long commands up into a series of shorter commands. | |
118 | ||
119 | C<split_command> will return a series of @cmds each processing part of | |
120 | the args. Collectively they will process all the arguments. Each | |
121 | individual line in @cmds will not be longer than the | |
122 | $self->max_exec_len being careful to take into account macro expansion. | |
123 | ||
124 | $cmd should include any switches and repeated initial arguments. | |
125 | ||
126 | If no @args are given, no @cmds will be returned. | |
127 | ||
128 | Pairs of arguments will always be preserved in a single command, this | |
129 | is a heuristic for things like pm_to_blib and pod2man which work on | |
130 | pairs of arguments. This makes things like this safe: | |
131 | ||
132 | $self->split_command($cmd, %pod2man); | |
133 | ||
134 | ||
135 | =cut | |
136 | ||
137 | sub split_command { | |
138 | my($self, $cmd, @args) = @_; | |
139 | ||
140 | my @cmds = (); | |
141 | return(@cmds) unless @args; | |
142 | ||
143 | # If the command was given as a here-doc, there's probably a trailing | |
144 | # newline. | |
145 | chomp $cmd; | |
146 | ||
147 | # set aside 20% for macro expansion. | |
148 | my $len_left = int($self->max_exec_len * 0.80); | |
149 | $len_left -= length $self->_expand_macros($cmd); | |
150 | ||
151 | do { | |
152 | my $arg_str = ''; | |
153 | my @next_args; | |
154 | while( @next_args = splice(@args, 0, 2) ) { | |
155 | # Two at a time to preserve pairs. | |
156 | my $next_arg_str = "\t ". join ' ', @next_args, "\n"; | |
157 | ||
158 | if( !length $arg_str ) { | |
159 | $arg_str .= $next_arg_str | |
160 | } | |
161 | elsif( length($arg_str) + length($next_arg_str) > $len_left ) { | |
162 | unshift @args, @next_args; | |

191 | my @commands = $MM->echo($text, $file); | |
192 | my @commands = $MM->echo($text, $file, $appending); | |
193 | ||
194 | Generates a set of @commands which print the $text to a $file. | |
195 | ||
196 | If $file is not given, output goes to STDOUT. | |
197 | ||
198 | If $appending is true the $file will be appended to rather than | |
199 | overwritten. | |
200 | ||
201 | =cut | |

203 | sub echo { | |

218 | ||
219 | =head3 wraplist | |
220 | ||
221 | my $args = $mm->wraplist(@list); | |
222 | ||
223 | Takes an array of items and turns them into a well-formatted list of | |
224 | arguments. In most cases this is simply something like: | |
225 | ||
226 | FOO \ | |
227 | BAR \ | |
228 | BAZ | |
229 | ||
230 | =cut | |
231 | ||
232 | sub wraplist { | |
233 | my $self = shift; | |
234 | return join " \\\n\t", @_; | |
235 | } | |
236 | ||
237 | ||
238 | =head3 cd I<Abstract> | |
239 | ||
240 | my $subdir_cmd = $MM->cd($subdir, @cmds); | |
241 | ||
242 | This will generate a make fragment which runs the @cmds in the given | |
243 | $dir. The rough equivalent to this, except cross platform. | |
244 | ||
245 | cd $subdir && $cmd | |
246 | ||
247 | Currently $dir can only go down one level. "foo" is fine. "foo/bar" is | |
248 | not. "../foo" is right out. | |
249 | ||
250 | The resulting $subdir_cmd has no leading tab nor trailing newline. This | |
251 | makes it easier to embed in a make string. For example. | |
252 | ||
253 | my $make = sprintf <<'CODE', $subdir_cmd; | |
254 | foo : | |
255 | $(ECHO) what | |
256 | %s | |
257 | $(ECHO) mouche | |

261 | =head3 oneliner I<Abstract> | |
262 | ||
263 | my $oneliner = $MM->oneliner($perl_code); | |
264 | my $oneliner = $MM->oneliner($perl_code, \@switches); | |
265 | ||
266 | This will generate a perl one-liner safe for the particular platform | |
267 | you're on based on the given $perl_code and @switches (a -e is | |
268 | assumed) suitable for using in a make target. It will use the proper | |
269 | shell quoting and escapes. | |
270 | ||
271 | $(PERLRUN) will be used as perl. | |
272 | ||
273 | Any newlines in $perl_code will be escaped. Leading and trailing | |
274 | newlines will be stripped. Makes this idiom much easier: | |
275 | ||
276 | my $code = $MM->oneliner(<<'CODE', [...switches...]); | |
277 | some code here | |
278 | another line here | |
279 | CODE | |
280 | ||
281 | Usage might be something like: | |
282 | ||
283 | # an echo emulation | |
284 | $oneliner = $MM->oneliner('print "Foo\n"'); | |
285 | $make = '$oneliner > somefile'; | |
286 | ||
287 | All dollar signs must be doubled in the $perl_code if you expect them | |
288 | to be interpreted normally, otherwise it will be considered a make | |
289 | macro. Also remember to quote make macros else it might be used as a | |
290 | bareword. For example: | |
291 | ||
292 | # Assign the value of the $(VERSION_FROM) make macro to $vf. | |
293 | $oneliner = $MM->oneliner('$$vf = "$(VERSION_FROM)"'); | |
294 | ||
295 | Its currently very simple and may be expanded sometime in the figure | |
296 | to include more flexible code and switches. | |
297 | ||
298 | ||
299 | =head3 quote_literal I<Abstract> | |
300 | ||
301 | my $safe_text = $MM->quote_literal($text); | |
302 | ||
303 | This will quote $text so it is interpreted literally in the shell. | |
304 | ||
305 | For example, on Unix this would escape any single-quotes in $text and | |
306 | put single-quotes around the whole thing. | |
307 | ||
308 | ||
309 | =head3 escape_newlines I<Abstract> | |
310 | ||
311 | my $escaped_text = $MM->escape_newlines($text); | |
312 | ||
313 | Shell escapes newlines in $text. | |
314 | ||
315 | ||
316 | =head3 max_exec_len I<Abstract> | |
317 | ||
318 | my $max_exec_len = $MM->max_exec_len; | |
319 | ||
320 | Calculates the maximum command size the OS can exec. Effectively, | |
321 | this is the max size of a shell command line. | |
322 | ||
323 | =for _private | |
324 | $self->{_MAX_EXEC_LEN} is set by this method, but only for testing purposes. | |
325 | ||

1387 | nothing on VMS. | |
1388 | ||
1389 | For example: | |
1390 | ||
1391 | # instead of $(INST_ARCHAUTODIR)/extralibs.ld | |
1392 | $(INST_ARCHAUTODIR)$(DIRFILESEP)extralibs.ld | |

1394 | Something of a hack but it prevents a lot of code duplication between | |
1395 | MM_* variants. | |
1396 | ||
1397 | Do not use this as a seperator between directories. Some operating | |

1410 | PERL_ARCHIVE_AFTER: path to a library which should be put on the | |
1411 | linker command line I<after> the external libraries to be linked to | |
1412 | dynamic extensions. This may be needed if the linker is one-pass, and | |
1413 | Perl includes some overrides for C RTL functions, such as malloc(). | |
1414 | ||
1415 | EXPORT_LIST: name of a file that is passed to linker to define symbols | |
1416 | to be exported. | |
