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 30% for macro expansion.
148 my $len_left = int($self->max_exec_len * 0.70);
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 maketext_filter
240 my $filter_make_text = $mm->maketext_filter($make_text);
242 The text of the Makefile is run through this method before writing to
243 disk. It allows systems a chance to make portability fixes to the
246 By default it does nothing.
248 This method is protected and not intended to be called outside of
253 sub maketext_filter { return $_[1] }
256 =head3 cd I<Abstract>
258 my $subdir_cmd = $MM->cd($subdir, @cmds);
260 This will generate a make fragment which runs the @cmds in the given
261 $dir. The rough equivalent to this, except cross platform.
265 Currently $dir can only go down one level. "foo" is fine. "foo/bar" is
266 not. "../foo" is right out.
268 The resulting $subdir_cmd has no leading tab nor trailing newline. This
269 makes it easier to embed in a make string. For example.
271 my $make = sprintf <<'CODE', $subdir_cmd;
279 =head3 oneliner I<Abstract>
281 my $oneliner = $MM->oneliner($perl_code);
282 my $oneliner = $MM->oneliner($perl_code, \@switches);
284 This will generate a perl one-liner safe for the particular platform
285 you're on based on the given $perl_code and @switches (a -e is
286 assumed) suitable for using in a make target. It will use the proper
287 shell quoting and escapes.
289 $(PERLRUN) will be used as perl.
291 Any newlines in $perl_code will be escaped. Leading and trailing
292 newlines will be stripped. Makes this idiom much easier:
294 my $code = $MM->oneliner(<<'CODE', [...switches...]);
299 Usage might be something like:
302 $oneliner = $MM->oneliner('print "Foo\n"');
303 $make = '$oneliner > somefile';
305 All dollar signs must be doubled in the $perl_code if you expect them
306 to be interpreted normally, otherwise it will be considered a make
307 macro. Also remember to quote make macros else it might be used as a
308 bareword. For example:
310 # Assign the value of the $(VERSION_FROM) make macro to $vf.
311 $oneliner = $MM->oneliner('$$vf = "$(VERSION_FROM)"');
313 Its currently very simple and may be expanded sometime in the figure
314 to include more flexible code and switches.
317 =head3 quote_literal I<Abstract>
319 my $safe_text = $MM->quote_literal($text);
321 This will quote $text so it is interpreted literally in the shell.
323 For example, on Unix this would escape any single-quotes in $text and
324 put single-quotes around the whole thing.
327 =head3 escape_newlines I<Abstract>
329 my $escaped_text = $MM->escape_newlines($text);
331 Shell escapes newlines in $text.
334 =head3 max_exec_len I<Abstract>
336 my $max_exec_len = $MM->max_exec_len;
338 Calculates the maximum command size the OS can exec. Effectively,
339 this is the max size of a shell command line.
342 $self->{_MAX_EXEC_LEN} is set by this method, but only for testing purposes.
347 my $make = $MM->make;
349 Returns the make variant we're generating the Makefile for. This attempts
350 to do some normalization on the information from %Config or the user.
357 my $make = lc $self->{MAKE};
359 # Truncate anything like foomake6 to just foomake.
360 $make =~ s/^(\w+make).*/$1/;
362 # Turn gnumake into gmake.
371 These are methods which produce make targets.
376 Generate the default target 'all'.
