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.
46 Subclass off of ExtUtils::MM_Any I<and> ExtUtils::MM_Unix. This is a
49 B<THIS MAY BE TEMPORARY!>
54 Any methods marked I<Abstract> must be implemented by subclasses.
57 =head2 Cross-platform helper methods
59 These are methods which help writing cross-platform code.
63 =head3 os_flavor I<Abstract>
65 my @os_flavor = $mm->os_flavor;
67 @os_flavor is the style of operating system this is, usually
68 corresponding to the MM_*.pm file we're using.
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.
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')
82 This is used to write code for styles of operating system.
83 See os_flavor_is() for use.
88 my $is_this_flavor = $mm->os_flavor_is($this_flavor);
89 my $is_this_flavor = $mm->os_flavor_is(@one_of_these_flavors);
91 Checks to see if the current operating system is one of the given flavors.
93 This is useful for code like:
95 if( $mm->os_flavor_is('Unix') ) {
106 my %flavors = map { ($_ => 1) } $self->os_flavor;
107 return (grep { $flavors{$_} } @_) ? 1 : 0;
113 my @cmds = $MM->split_command($cmd, @args);
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.
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.
124 $cmd should include any switches and repeated initial arguments.
126 If no @args are given, no @cmds will be returned.
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:
132 $self->split_command($cmd, %pod2man);
138 my($self, $cmd, @args) = @_;
141 return(@cmds) unless @args;
143 # If the command was given as a here-doc, there's probably a trailing
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);
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";
158 if( !length $arg_str ) {
159 $arg_str .= $next_arg_str
161 elsif( length($arg_str) + length($next_arg_str) > $len_left ) {
162 unshift @args, @next_args;
166 $arg_str .= $next_arg_str;
171 push @cmds, $self->escape_newlines("$cmd \n$arg_str");
179 my($self, $cmd) = @_;
181 $cmd =~ s{\$\((\w+)\)}{
182 defined $self->{$1} ? $self->{$1} : "\$($1)"
190 my @commands = $MM->echo($text);
191 my @commands = $MM->echo($text, $file);
192 my @commands = $MM->echo($text, $file, $appending);
194 Generates a set of @commands which print the $text to a $file.
196 If $file is not given, output goes to STDOUT.
198 If $appending is true the $file will be appended to rather than
204 my($self, $text, $file, $appending) = @_;
207 my @cmds = map { '$(NOECHO) $(ECHO) '.$self->quote_literal($_) }
210 my $redirect = $appending ? '>>' : '>';
211 $cmds[0] .= " $redirect $file";
212 $_ .= " >> $file" foreach @cmds[1..$#cmds];
221 my $args = $mm->wraplist(@list);
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:
234 return join " \\\n\t", @_;
238 =head3 cd I<Abstract>
240 my $subdir_cmd = $MM->cd($subdir, @cmds);
242 This will generate a make fragment which runs the @cmds in the given
243 $dir. The rough equivalent to this, except cross platform.
247 Currently $dir can only go down one level. "foo" is fine. "foo/bar" is
248 not. "../foo" is right out.
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.
253 my $make = sprintf <<'CODE', $subdir_cmd;
261 =head3 oneliner I<Abstract>
263 my $oneliner = $MM->oneliner($perl_code);
264 my $oneliner = $MM->oneliner($perl_code, \@switches);
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.
271 $(PERLRUN) will be used as perl.
273 Any newlines in $perl_code will be escaped. Leading and trailing
274 newlines will be stripped. Makes this idiom much easier:
276 my $code = $MM->oneliner(<<'CODE', [...switches...]);
281 Usage might be something like:
284 $oneliner = $MM->oneliner('print "Foo\n"');
285 $make = '$oneliner > somefile';
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:
292 # Assign the value of the $(VERSION_FROM) make macro to $vf.
293 $oneliner = $MM->oneliner('$$vf = "$(VERSION_FROM)"');
295 Its currently very simple and may be expanded sometime in the figure
296 to include more flexible code and switches.
299 =head3 quote_literal I<Abstract>
301 my $safe_text = $MM->quote_literal($text);
303 This will quote $text so it is interpreted literally in the shell.
305 For example, on Unix this would escape any single-quotes in $text and
306 put single-quotes around the whole thing.
309 =head3 escape_newlines I<Abstract>
311 my $escaped_text = $MM->escape_newlines($text);
313 Shell escapes newlines in $text.
316 =head3 max_exec_len I<Abstract>
318 my $max_exec_len = $MM->max_exec_len;
320 Calculates the maximum command size the OS can exec. Effectively,
321 this is the max size of a shell command line.
324 $self->{_MAX_EXEC_LEN} is set by this method, but only for testing purposes.
332 These are methods which produce make targets.
337 Generate the default target 'all'.
352 =head3 blibdirs_target
354 my $make_frag = $mm->blibdirs_target;
356 Creates the blibdirs target which creates all the directories we use

1349 Defines at least these macros.

1389 # instead of $(INST_ARCHAUTODIR)/extralibs.ld
1390 $(INST_ARCHAUTODIR)$(DIRFILESEP)extralibs.ld
1392 Something of a hack but it prevents a lot of code duplication between
1395 Do not use this as a seperator between directories. Some operating
1396 systems use different seperators between subdirectories as between
1397 directories and filenames (for example: VOLUME:[dir1.dir2]file on VMS).
1399 =head3 init_linker I<Abstract>
1403 Initialize macros which have to do with linking.
1405 PERL_ARCHIVE: path to libperl.a equivalent to be linked to dynamic
1408 PERL_ARCHIVE_AFTER: path to a library which should be put on the
1409 linker command line I<after> the external libraries to be linked to
1410 dynamic extensions. This may be needed if the linker is one-pass, and
1411 Perl includes some overrides for C RTL functions, such as malloc().

1416 Some OSes do not need these in which case leave it blank.
1419 =head3 init_platform
1423 Initialize any macros which are for platform specific use only.
1425 A typical one is the version number of your OS specific mocule.
1426 (ie. MM_Unix_VERSION or MM_VMS_VERSION).
1440 A grab bag of methods to generate specific macros and commands.

1474 command by simply appending them on the macro.
