=head1 NAME
ExtUtils::MM_Any - Platform-agnostic MM methods
=head1 SYNOPSIS
FOR INTERNAL USE ONLY!
package ExtUtils::MM_SomeOS;
# Temporarily, you have to subclass both. Put MM_Any first.
require ExtUtils::MM_Any;
require ExtUtils::MM_Unix;
@ISA = qw(ExtUtils::MM_Any ExtUtils::Unix);
=head1 DESCRIPTION
B<FOR INTERNAL USE ONLY!>
ExtUtils::MM_Any is a superclass for the ExtUtils::MM_* set of
modules. It contains methods which are either inherently
cross-platform or are written in a cross-platform manner.
Subclass off of ExtUtils::MM_Any I<and> ExtUtils::MM_Unix. This is a
temporary solution.
B<THIS MAY BE TEMPORARY!>
=head1 METHODS
Any methods marked I<Abstract> must be implemented by subclasses.
=head2 Cross-platform helper methods
These are methods which help writing cross-platform code.
=head3 os_flavor I<Abstract>
my @os_flavor = $mm->os_flavor;
@os_flavor is the style of operating system this is, usually
corresponding to the MM_*.pm file we're using.
The first element of @os_flavor is the major family (ie. Unix,
Windows, VMS, OS/2, etc...) and the rest are sub families.
Some examples:
Cygwin98 ('Unix', 'Cygwin', 'Cygwin9x')
Windows ('Win32')
Win98 ('Win32', 'Win9x')
Linux ('Unix', 'Linux')
MacOS X ('Unix', 'Darwin', 'MacOS', 'MacOS X')
OS/2 ('OS/2')
This is used to write code for styles of operating system.
See os_flavor_is() for use.
=head3 os_flavor_is
my $is_this_flavor = $mm->os_flavor_is($this_flavor);
my $is_this_flavor = $mm->os_flavor_is(@one_of_these_flavors);
Checks to see if the current operating system is one of the given flavors.
This is useful for code like:
if( $mm->os_flavor_is('Unix') ) {
$out = `foo 2>&1`;
}
else {
$out = `foo`;
}
=cut
sub os_flavor_is {
my $self = shift;
my %flavors = map { ($_ => 1) } $self->os_flavor;
return (grep { $flavors{$_} } @_) ? 1 : 0;
}
=head3 can_load_xs
my $can_load_xs = $self->can_load_xs;
Returns true if we have the ability to load XS.
This is important because miniperl, used to build XS modules in the
core, can not load XS.
=cut
sub can_load_xs {
return defined &DynaLoader::boot_DynaLoader ? 1 : 0;
}
=head3 can_run
use ExtUtils::MM;
my $runnable = MM->can_run($Config{make});
If called in a scalar context it will return the full path to the binary
you asked for if it was found, or C<undef> if it was not.
If called in a list context, it will return a list of the full paths to instances
of the binary where found in C<PATH>, or an empty list if it was not found.
Copied from L<IPC::Cmd|IPC::Cmd/"$path = can_run( PROGRAM );">, but modified into
a method (and removed C<$INSTANCES> capability).
=cut
sub can_run {
my ($self, $command) = @_;
# a lot of VMS executables have a symbol defined
# check those first
if ( $^O eq 'VMS' ) {
require VMS::DCLsym;
my $syms = VMS::DCLsym->new;
return $command if scalar $syms->getsym( uc $command );
}
my @possibles;
if( File::Spec->file_name_is_absolute($command) ) {
return $self->maybe_command($command);
} else {
for my $dir (
File::Spec->path,
File::Spec->curdir
) {
next if ! $dir || ! -d $dir;
my $abs = File::Spec->catfile($self->os_flavor_is('Win32') ? Win32::GetShortPathName( $dir ) : $dir, $command);
push @possibles, $abs if $abs = $self->maybe_command($abs);
}
}
return @possibles if wantarray;
return shift @possibles;
}
=head3 can_redirect_error
$useredirect = MM->can_redirect_error;
True if on an OS where qx operator (or backticks) can redirect C<STDERR>
onto C<STDOUT>.
=cut
sub can_redirect_error {
my $self = shift;
$self->os_flavor_is('Unix')
or ($self->os_flavor_is('Win32') and !$self->os_flavor_is('Win9x'))
or $self->os_flavor_is('OS/2')
}
=head3 is_make_type
my $is_dmake = $self->is_make_type('dmake');
Returns true if C<<$self->make>> is the given type; possibilities are:
gmake GNU make
dmake
nmake
bsdmake BSD pmake-derived
=cut
my %maketype2true;
# undocumented - so t/cd.t can still do its thing
sub _clear_maketype_cache { %maketype2true = () }
sub is_make_type {
my($self, $type) = @_;
return $maketype2true{$type} if defined $maketype2true{$type};
(undef, undef, my $make_basename) = $self->splitpath($self->make);
return $maketype2true{$type} = 1
if $make_basename =~ /\b$type\b/i; # executable's filename
return $maketype2true{$type} = 0
if $make_basename =~ /\b[gdn]make\b/i; # Never fall through for dmake/nmake/gmake
# now have to run with "-v" and guess
my $redirect = $self->can_redirect_error ? '2>&1' : '';
my $make = $self->make || $self->{MAKE};
my $minus_v = `"$make" -v $redirect`;
return $maketype2true{$type} = 1
if $type eq 'gmake' and $minus_v =~ /GNU make/i;
return $maketype2true{$type} = 1
if $type eq 'bsdmake'
and $minus_v =~ /^usage: make \[-BeikNnqrstWwX\]/im;
$maketype2true{$type} = 0; # it wasn't whatever you asked
}
=head3 can_dep_space
my $can_dep_space = $self->can_dep_space;
Returns true if C<make> can handle (probably by quoting)
dependencies that contain a space. Currently known true for GNU make,
false for BSD pmake derivative.
=cut
my $cached_dep_space;
sub can_dep_space {
my $self = shift;
return $cached_dep_space if defined $cached_dep_space;
return $cached_dep_space = 1 if $self->is_make_type('gmake');
return $cached_dep_space = 0 if $self->is_make_type('dmake'); # only on W32
return $cached_dep_space = 0 if $self->is_make_type('bsdmake');
return $cached_dep_space = 0; # assume no
}
=head3 quote_dep
$text = $mm->quote_dep($text);
Method that protects Makefile single-value constants (mainly filenames),
so that make will still treat them as single values even if they
inconveniently have spaces in. If the make program being used cannot
achieve such protection and the given text would need it, throws an
exception.
=cut
sub quote_dep {
my ($self, $arg) = @_;
die <<EOF if $arg =~ / / and not $self->can_dep_space;
Tried to use make dependency with space for make that can't:
'$arg'
EOF
$arg =~ s/( )/\\$1/g; # how GNU make does it
return $arg;
}
=head3 split_command
my @cmds = $MM->split_command($cmd, @args);
Most OS have a maximum command length they can execute at once. Large
modules can easily generate commands well past that limit. Its
necessary to split long commands up into a series of shorter commands.
C<split_command> will return a series of @cmds each processing part of
the args. Collectively they will process all the arguments. Each
individual line in @cmds will not be longer than the
$self->max_exec_len being careful to take into account macro expansion.
$cmd should include any switches and repeated initial arguments.
If no @args are given, no @cmds will be returned.
Pairs of arguments will always be preserved in a single command, this
is a heuristic for things like pm_to_blib and pod2man which work on
pairs of arguments. This makes things like this safe:
$self->split_command($cmd, %pod2man);
=cut
sub split_command {
my($self, $cmd, @args) = @_;
my @cmds = ();
return(@cmds) unless @args;
# If the command was given as a here-doc, there's probably a trailing
# newline.
chomp $cmd;
# set aside 30% for macro expansion.
my $len_left = int($self->max_exec_len * 0.70);
$len_left -= length $self->_expand_macros($cmd);
do {
my $arg_str = '';
my @next_args;
while( @next_args = splice(@args, 0, 2) ) {
# Two at a time to preserve pairs.
my $next_arg_str = "\t ". join ' ', @next_args, "\n";
if( !length $arg_str ) {
$arg_str .= $next_arg_str
}
elsif( length($arg_str) + length($next_arg_str) > $len_left ) {
unshift @args, @next_args;
last;
}
else {
$arg_str .= $next_arg_str;
}
}
chop $arg_str;
push @cmds, $self->escape_newlines("$cmd \n$arg_str");
} while @args;
return @cmds;
}
sub _expand_macros {
my($self, $cmd) = @_;
$cmd =~ s{\$\((\w+)\)}{
defined $self->{$1} ? $self->{$1} : "\$($1)"
}e;
return $cmd;
}
=head3 make_type
Returns a suitable string describing the type of makefile being written.
=cut
# override if this isn't suitable!
sub make_type { return 'Unix-style'; }
=head3 stashmeta
my @recipelines = $MM->stashmeta($text, $file);
Generates a set of C<@recipelines> which will result in the literal
C<$text> ending up in literal C<$file> when the recipe is executed. Call
it once, with all the text you want in C<$file>. Make macros will not
be expanded, so the locations will be fixed at configure-time, not
at build-time.
=cut
sub stashmeta {
my($self, $text, $file) = @_;
$self->echo($text, $file, { allow_variables => 0, append => 0 });
}
=head3 echo
my @commands = $MM->echo($text);
my @commands = $MM->echo($text, $file);
my @commands = $MM->echo($text, $file, \%opts);
Generates a set of @commands which print the $text to a $file.
If $file is not given, output goes to STDOUT.
If $opts{append} is true the $file will be appended to rather than
overwritten. Default is to overwrite.
If $opts{allow_variables} is true, make variables of the form
C<$(...)> will not be escaped. Other C<$> will. Default is to escape
all C<$>.
Example of use:
my $make = join '', map "\t$_\n", $MM->echo($text, $file);
=cut
sub echo {
my($self, $text, $file, $opts) = @_;
# Compatibility with old options
if( !ref $opts ) {
my $append = $opts;
$opts = { append => $append || 0 };
}
$opts->{allow_variables} = 0 unless defined $opts->{allow_variables};
my $ql_opts = { allow_variables => $opts->{allow_variables} };
my @cmds = map { '$(NOECHO) $(ECHO) '.$self->quote_literal($_, $ql_opts) }
split /\n/, $text;
if( $file ) {
my $redirect = $opts->{append} ? '>>' : '>';
$cmds[0] .= " $redirect $file";
$_ .= " >> $file" foreach @cmds[1..$#cmds];
}
return @cmds;
}
=head3 wraplist
my $args = $mm->wraplist(@list);
Takes an array of items and turns them into a well-formatted list of
arguments. In most cases this is simply something like:
FOO \
BAR \
BAZ
=cut
sub wraplist {
my $self = shift;
return join " \\\n\t", @_;
}
=head3 maketext_filter
my $filter_make_text = $mm->maketext_filter($make_text);
The text of the Makefile is run through this method before writing to
disk. It allows systems a chance to make portability fixes to the
Makefile.
By default it does nothing.
This method is protected and not intended to be called outside of
MakeMaker.
=cut
sub maketext_filter { return $_[1] }
=head3 cd I<Abstract>
my $subdir_cmd = $MM->cd($subdir, @cmds);
This will generate a make fragment which runs the @cmds in the given
$dir. The rough equivalent to this, except cross platform.
cd $subdir && $cmd
Currently $dir can only go down one level. "foo" is fine. "foo/bar" is
not. "../foo" is right out.
The resulting $subdir_cmd has no leading tab nor trailing newline. This
makes it easier to embed in a make string. For example.
my $make = sprintf <<'CODE', $subdir_cmd;
foo :
$(ECHO) what
%s
$(ECHO) mouche
CODE
=head3 oneliner I<Abstract>
my $oneliner = $MM->oneliner($perl_code);
my $oneliner = $MM->oneliner($perl_code, \@switches);
This will generate a perl one-liner safe for the particular platform
you're on based on the given $perl_code and @switches (a -e is
assumed) suitable for using in a make target. It will use the proper
shell quoting and escapes.
$(PERLRUN) will be used as perl.
Any newlines in $perl_code will be escaped. Leading and trailing
newlines will be stripped. Makes this idiom much easier:
my $code = $MM->oneliner(<<'CODE', [...switches...]);
some code here
another line here
CODE
Usage might be something like:
# an echo emulation
$oneliner = $MM->oneliner('print "Foo\n"');
$make = '$oneliner > somefile';
Dollar signs in the $perl_code will be protected from make using the
C<quote_literal> method, unless they are recognised as being a make
variable, C<$(varname)>, in which case they will be left for make
to expand. Remember to quote make macros else it might be used as a
bareword. For example:
# Assign the value of the $(VERSION_FROM) make macro to $vf.
$oneliner = $MM->oneliner('$vf = "$(VERSION_FROM)"');
Its currently very simple and may be expanded sometime in the figure
to include more flexible code and switches.
=head3 quote_literal I<Abstract>
my $safe_text = $MM->quote_literal($text);
my $safe_text = $MM->quote_literal($text, \%options);
This will quote $text so it is interpreted literally in the shell.
For example, on Unix this would escape any single-quotes in $text and
put single-quotes around the whole thing.
If $options{allow_variables} is true it will leave C<'$(FOO)'> make
variables untouched. If false they will be escaped like any other
C<$>. Defaults to true.
=head3 escape_dollarsigns
my $escaped_text = $MM->escape_dollarsigns($text);
Escapes stray C<$> so they are not interpreted as make variables.
It lets by C<$(...)>.
=cut
sub escape_dollarsigns {
my($self, $text) = @_;
# Escape dollar signs which are not starting a variable
$text =~ s{\$ (?!\() }{\$\$}gx;
return $text;
}
=head3 escape_all_dollarsigns
my $escaped_text = $MM->escape_all_dollarsigns($text);
Escapes all C<$> so they are not interpreted as make variables.
=cut
sub escape_all_dollarsigns {
my($self, $text) = @_;
# Escape dollar signs
$text =~ s{\$}{\$\$}gx;
return $text;
}
=head3 escape_newlines I<Abstract>
my $escaped_text = $MM->escape_newlines($text);
Shell escapes newlines in $text.
=head3 max_exec_len I<Abstract>
my $max_exec_len = $MM->max_exec_len;
Calculates the maximum command size the OS can exec. Effectively,
this is the max size of a shell command line.
=for _private
$self->{_MAX_EXEC_LEN} is set by this method, but only for testing purposes.
=head3 make
my $make = $MM->make;
Returns the make variant we're generating the Makefile for. This attempts
to do some normalization on the information from %Config or the user.
=cut
sub make {
my $self = shift;
my $make = lc $self->{MAKE};
# Truncate anything like foomake6 to just foomake.
$make =~ s/^(\w+make).*/$1/;
# Turn gnumake into gmake.
$make =~ s/^gnu/g/;

Generates targets to create the specified directories and set its

too well (the modified time changes too often) dir_target() creates a
.exists file in the created directory. It is this you should depend on.
For portability purposes you should use the $(DIRFILESEP) macro rather
than a '/' to separate the directory from the file.

keys and values of the same hash

It may be undef, which means no sorting by keys

Initializes the DIRFILESEP macro which is the separator between the

nothing on VMS.
For example:
# instead of $(INST_ARCHAUTODIR)/extralibs.ld
$(INST_ARCHAUTODIR)$(DIRFILESEP)extralibs.ld
Something of a hack but it prevents a lot of code duplication between
MM_* variants.
Do not use this as a separator between directories. Some operating
systems use different separators between subdirectories as between
directories and filenames (for example: VOLUME:[dir1.dir2]file on VMS).
=head3 init_linker I<Abstract>
$mm->init_linker;
Initialize macros which have to do with linking.
PERL_ARCHIVE: path to libperl.a equivalent to be linked to dynamic
extensions.
PERL_ARCHIVE_AFTER: path to a library which should be put on the
linker command line I<after> the external libraries to be linked to
dynamic extensions. This may be needed if the linker is one-pass, and
Perl includes some overrides for C RTL functions, such as malloc().
EXPORT_LIST: name of a file that is passed to linker to define symbols
to be exported.
Some OSes do not need these in which case leave it blank.
=head3 init_platform
$mm->init_platform

Returns a definition for the POD2MAN macro. This is a program
which emulates the pod2man utility. You can add more switches to the

A sanity check that what Perl thinks the architecture is and what
Config thinks the architecture is are the same. If they're not it
will return false and show a diagnostic message.
When building Perl it will always return true, as nothing is installed
yet.
The interface is a bit odd because this is the result of a
quick refactoring. Don't rely on it.

Takes a path to a file or dir and returns an empty string if we don't
want to include this file in the library. Otherwise it returns the
the $path unchanged.
Mainly used to exclude version control administrative directories
and base-level F<README.pod> from installation.

my $perl_header_files_fragment= $self->_perl_header_files_fragment("/");
return a Makefile fragment which holds the list of perl header files which
XS code depends on $(PERL_INC), and sets up the dependency for the $(OBJECT) file.
The $separator argument defaults to "". MM_VMS will set it to "" and MM_UNIX to "/"
in perldepend(). This reason child subclasses need to control this is that in
VMS the $(PERL_INC) directory will already have delimiters in it, but in
UNIX $(PERL_INC) will need a slash between it an the filename. Hypothetically
win32 could use "\\" (but it doesn't need to).
