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.
47 Subclass off of ExtUtils::MM_Any I<and> ExtUtils::MM_Unix. This is a
50 B<THIS MAY BE TEMPORARY!>
55 Any methods marked I<Abstract> must be implemented by subclasses.
58 =head2 Cross-platform helper methods
60 These are methods which help writing cross-platform code.
64 =head3 os_flavor I<Abstract>
66 my @os_flavor = $mm->os_flavor;
68 @os_flavor is the style of operating system this is, usually
69 corresponding to the MM_*.pm file we're using.
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.
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')
83 This is used to write code for styles of operating system.
84 See os_flavor_is() for use.
89 my $is_this_flavor = $mm->os_flavor_is($this_flavor);
90 my $is_this_flavor = $mm->os_flavor_is(@one_of_these_flavors);
92 Checks to see if the current operating system is one of the given flavors.
94 This is useful for code like:
96 if( $mm->os_flavor_is('Unix') ) {
107 my %flavors = map { ($_ => 1) } $self->os_flavor;
108 return (grep { $flavors{$_} } @_) ? 1 : 0;
114 my @cmds = $MM->split_command($cmd, @args);
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.
120 C<split_command> will return a series of @cmds each processing part of
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.
125 $cmd should include any switches and repeated initial arguments.
127 If no @args are given, no @cmds will be returned.
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:
133 $self->split_command($cmd, %pod2man);
139 my($self, $cmd, @args) = @_;
142 return(@cmds) unless @args;
144 # If the command was given as a here-doc, there's probably a trailing
148 # set aside 20% for macro expansion.
149 my $len_left = int($self->max_exec_len * 0.80);
150 $len_left -= length $self->_expand_macros($cmd);
155 while( @next_args = splice(@args, 0, 2) ) {
156 # Two at a time to preserve pairs.
157 my $next_arg_str = "\t ". join ' ', @next_args, "\n";
159 if( !length $arg_str ) {
160 $arg_str .= $next_arg_str
162 elsif( length($arg_str) + length($next_arg_str) > $len_left ) {
163 unshift @args, @next_args;
167 $arg_str .= $next_arg_str;
172 push @cmds, $self->escape_newlines("$cmd \n$arg_str");
180 my($self, $cmd) = @_;
182 $cmd =~ s{\$\((\w+)\)}{
183 defined $self->{$1} ? $self->{$1} : "\$($1)"
191 my @commands = $MM->echo($text);
192 my @commands = $MM->echo($text, $file);
193 my @commands = $MM->echo($text, $file, $appending);
195 Generates a set of @commands which print the $text to a $file.
197 If $file is not given, output goes to STDOUT.
199 If $appending is true the $file will be appended to rather than
205 my($self, $text, $file, $appending) = @_;
208 my @cmds = map { '$(NOECHO) $(ECHO) '.$self->quote_literal($_) }
211 my $redirect = $appending ? '>>' : '>';
212 $cmds[0] .= " $redirect $file";
213 $_ .= " >> $file" foreach @cmds[1..$#cmds];
222 my $args = $mm->wraplist(@list);
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:
235 return join " \\\n\t", @_;
239 =head3 maketext_filter
241 my $filter_make_text = $mm->maketext_filter($make_text);
243 The text of the Makefile is run through this method before writing to
244 disk. It allows systems a chance to make portability fixes to the
247 By default it does nothing.
249 This method is protected and not intended to be called outside of
254 sub maketext_filter { return $_[1] }
257 =head3 cd I<Abstract>
259 my $subdir_cmd = $MM->cd($subdir, @cmds);
261 This will generate a make fragment which runs the @cmds in the given
262 $dir. The rough equivalent to this, except cross platform.
266 Currently $dir can only go down one level. "foo" is fine. "foo/bar" is
267 not. "../foo" is right out.
269 The resulting $subdir_cmd has no leading tab nor trailing newline. This
270 makes it easier to embed in a make string. For example.
272 my $make = sprintf <<'CODE', $subdir_cmd;
280 =head3 oneliner I<Abstract>
282 my $oneliner = $MM->oneliner($perl_code);
283 my $oneliner = $MM->oneliner($perl_code, \@switches);
285 This will generate a perl one-liner safe for the particular platform
286 you're on based on the given $perl_code and @switches (a -e is
287 assumed) suitable for using in a make target. It will use the proper
288 shell quoting and escapes.
290 $(PERLRUN) will be used as perl.
292 Any newlines in $perl_code will be escaped. Leading and trailing
293 newlines will be stripped. Makes this idiom much easier:
295 my $code = $MM->oneliner(<<'CODE', [...switches...]);
300 Usage might be something like:
303 $oneliner = $MM->oneliner('print "Foo\n"');
304 $make = '$oneliner > somefile';
306 All dollar signs must be doubled in the $perl_code if you expect them
307 to be interpreted normally, otherwise it will be considered a make
308 macro. Also remember to quote make macros else it might be used as a
309 bareword. For example:
311 # Assign the value of the $(VERSION_FROM) make macro to $vf.
312 $oneliner = $MM->oneliner('$$vf = "$(VERSION_FROM)"');
314 Its currently very simple and may be expanded sometime in the figure
315 to include more flexible code and switches.
318 =head3 quote_literal I<Abstract>
320 my $safe_text = $MM->quote_literal($text);
322 This will quote $text so it is interpreted literally in the shell.
324 For example, on Unix this would escape any single-quotes in $text and
325 put single-quotes around the whole thing.
328 =head3 escape_newlines I<Abstract>
330 my $escaped_text = $MM->escape_newlines($text);
332 Shell escapes newlines in $text.
335 =head3 max_exec_len I<Abstract>
337 my $max_exec_len = $MM->max_exec_len;
339 Calculates the maximum command size the OS can exec. Effectively,
340 this is the max size of a shell command line.
343 $self->{_MAX_EXEC_LEN} is set by this method, but only for testing purposes.
348 my $make = $MM->make;
350 Returns the make variant we're generating the Makefile for. This attempts
351 to do some normalization on the information from %Config or the user.
358 my $make = lc $self->{MAKE};
360 # Truncate anything like foomake6 to just foomake.
361 $make =~ s/^(\w+make).*/$1/;
363 # Turn gnumake into gmake.
372 These are methods which produce make targets.
377 Generate the default target 'all'.

1478 # instead of $(INST_ARCHAUTODIR)/extralibs.ld
1479 $(INST_ARCHAUTODIR)$(DIRFILESEP)extralibs.ld

1500 Perl includes some overrides for C RTL functions, such as malloc().
