Instead, use ExtUtils::MM and it will figure out which MM_ class to use for you. =head1 DESCRIPTION See ExtUtils::MM_Unix for a documentation of the methods provided there. This package overrides the implementation of these methods, not the semantics. =head2 Methods always loaded =over 4 =item wraplist Converts a list into a string wrapped at approximately 80 columns. =cut sub wraplist { my($self) = shift; my($line,$hlen) = ('',0); foreach my $word (@_) { # Perl bug -- seems to occasionally insert extra elements when # traversing array (scalar(@array) doesn't show them, but # foreach(@array) does) (5.00307) next unless $word =~ /\w/; $line .= ' ' if length($line); if ($hlen > 80) { $line .= "\\\n\t"; $hlen = 0; } $line .= $word; $hlen += length($word) + 2; } $line; } # This isn't really an override. It's just here because ExtUtils::MM_VMS # appears in @MM::ISA before ExtUtils::Liblist::Kid, so if there isn't an ext() # in MM_VMS, then AUTOLOAD is called, and bad things happen. So, we just # mimic inheritance here and hand off to ExtUtils::Liblist::Kid. # XXX This hackery will die soon. --Schwern sub ext { require ExtUtils::Liblist::Kid; goto &ExtUtils::Liblist::Kid::ext; } =back =head2 Methods Those methods which override default MM_Unix methods are marked "(override)", while methods unique to MM_VMS are marked "(specific)". For overridden methods, documentation is limited to an explanation of why this method overrides the MM_Unix method; see the ExtUtils::MM_Unix documentation for more details. =over 4 =item guess_name (override) Try to determine name of extension being built. We begin with the name of the current directory. Since VMS filenames are case-insensitive, however, we look for a F<.pm> file whose name matches that of the current directory (presumably the 'main' F<.pm> file for this extension), and try to find a C<package> statement from which to obtain the Mixed::Case package name. =cut sub guess_name { my($self) = @_; my($defname,$defpm,@pm,%xs); local PM; $defname = basename(fileify($ENV{'DEFAULT'})); $defname =~ s![\d\-_]\.dir.$!!; # Clip off .dir;1 suffix, and package version $defpm = $defname; # Fallback in case for some reason a user has copied the files for an # extension into a working directory whose name doesn't reflect the # extension's name. We'll use the name of a unique .pm file, or the # first .pm file with a matching .xs file. if (not -e "${defpm}.pm") { @pm = glob('.pm'); s/.pm$// for @pm; if (@pm == 1) { ($defpm = $pm[0]) =~ s/.pm$//; } elsif (@pm) { %xs = map { s/.xs$//; ($_,1) } glob('.xs'); ## no critic if (keys %xs) { foreach my $pm (@pm) { $defpm = $pm, last if exists $xs{$pm}; } } } } if (open(my $pm, '<', "${defpm}.pm")){ while (<$pm>) { if (/^\spackage\s+([^;]+)/i) { $defname = $1; last; } } print "Warning (non-fatal): Couldn't find package name in ${defpm}.pm;\n\t", "defaulting package name to $defname\n" if eof($pm); close $pm; } else { print "Warning (non-fatal): Couldn't find ${defpm}.pm;\n\t", "defaulting package name to $defname\n"; } $defname =~ s#[\d.\-_]+$##; $defname; } =item find_perl (override) Use VMS file specification syntax and CLI commands to find and invoke Perl images. =cut sub find_perl { my($self, $ver, $names, $dirs, $trace) = @_; my($vmsfile,@sdirs,@snames,@cand); my($rslt); my($inabs) = 0; local TCF; if( $self->{PERL_CORE} ) { # Check in relative directories first, so we pick up the current # version of Perl if we're running MakeMaker as part of the main build. @sdirs = sort { my($absa) = $self->file_name_is_absolute($a); my($absb) = $self->file_name_is_absolute($b); if ($absa && $absb) { return $a cmp $b } else { return $absa ? 1 : ($absb ? -1 : ($a cmp $b)); } } @$dirs; # Check miniperl before perl, and check names likely to contain # version numbers before "generic" names, so we pick up an # executable that's less likely to be from an old installation. @snames = sort { my($ba) = $a =~ m!([^:>\]/]+)$!; # basename my($bb) = $b =~ m!([^:>\]/]+)$!; my($ahasdir) = (length($a) - length($ba) > 0); my($bhasdir) = (length($b) - length($bb) > 0); if ($ahasdir and not $bhasdir) { return 1; } elsif ($bhasdir and not $ahasdir) { return -1; } else { $bb =~ /\d/ <=> $ba =~ /\d/ or substr($ba,0,1) cmp substr($bb,0,1) or length($bb) <=> length($ba) } } @$names; } else { @sdirs = @$dirs; @snames = @$names; } # Image names containing Perl version use '_' instead of '.' under VMS s/\.(\d+)$/_$1/ for @snames; if ($trace >= 2){ print "Looking for perl $ver by these names:\n"; print "\t@snames,\n"; print "in these dirs:\n"; print "\t@sdirs\n"; } foreach my $dir (@sdirs){ next unless defined $dir; # $self->{PERL_SRC} may be undefined $inabs++ if $self->file_name_is_absolute($dir); if ($inabs == 1) { # We've covered relative dirs; everything else is an absolute # dir (probably an installed location).

"\n" . $Config{sharpbang} . "perl $arg\n"; } =item maybe_command (override) Follows VMS naming conventions for executable files. If the name passed in doesn't exactly match an executable file, appends F<.Exe> (or equivalent) to check for executable image, and F<.Com> to check for DCL procedure. If this fails, checks directories in DCL$PATH and finally F<Sys$System:> for an executable file having the name specified, with or without the F<.Exe>-equivalent suffix. =cut sub maybe_command { my($self,$file) = @_; return $file if -x $file && ! -d _; my(@dirs) = (''); my(@exts) = ('',$Config{'exe_ext'},'.exe','.com'); if ($file !~ m![/:>\]]!) { for (my $i = 0; defined $ENV{"DCL\$PATH;$i"}; $i++) { my $dir = $ENV{"DCL\$PATH;$i"}; $dir .= ':' unless $dir =~ m%[\]:]$%; push(@dirs,$dir); } push(@dirs,'Sys$System:'); foreach my $dir (@dirs) { my $sysfile = "$dir$file"; foreach my $ext (@exts) { return $file if -x "$sysfile$ext" && ! -d _; } } } return 0; } =item pasthru (override) The list of macro definitions to be passed through must be specified using the /MACRO qualifier and must not add another /DEFINE qualifier. We prepend our own comma here to the contents of $(PASTHRU_DEFINE) because it is often empty and a comma always present in CCFLAGS would generate a missing qualifier value error. =cut sub pasthru { my($self) = shift; my $pasthru = $self->SUPER::pasthru; $pasthru =~ s\|(PASTHRU\s=\s)\|$1/MACRO=(\|; $pasthru =~ s\|\n\z\|)\n\|m; $pasthru =~ s\|/defi?n?e?=\(?([^\),]+)\)?\|,$1\|ig; return $pasthru; } =item pm_to_blib (override) VMS wants a dot in every file so we can't have one called 'pm_to_blib', it becomes 'pm_to_blib.' and MMS/K isn't smart enough to know that when you have a target called 'pm_to_blib' it should look for 'pm_to_blib.'. So in VMS its pm_to_blib.ts. =cut sub pm_to_blib { my $self = shift; my $make = $self->SUPER::pm_to_blib; $make =~ s{^pm_to_blib :}{pm_to_blib.ts :}m; $make =~ s{\$\(TOUCH\) pm_to_blib}{\$(TOUCH) pm_to_blib.ts}; $make = <<'MAKE' . $make; # Dummy target to match Unix target name; we use pm_to_blib.ts as # timestamp file to avoid repeated invocations under VMS pm_to_blib : pm_to_blib.ts $(NOECHO) $(NOOP) MAKE return $make; } =item perl_script (override) If name passed in doesn't specify a readable file, appends F<.com> or F<.pl> and tries again, since it's customary to have file types on all files under VMS. =cut sub perl_script { my($self,$file) = @_; return $file if -r $file && ! -d _; return "$file.com" if -r "$file.com"; return "$file.pl" if -r "$file.pl"; return ''; } =item replace_manpage_separator Use as separator a character which is legal in a VMS-syntax file name. =cut sub replace_manpage_separator { my($self,$man) = @_; $man = unixify($man); $man =~ s#/+#__#g; $man; } =item init_DEST (override) Because of the difficulty concatenating VMS filepaths we must pre-expand the DEST* variables. =cut sub init_DEST { my $self = shift; $self->SUPER::init_DEST; # Expand DEST variables. foreach my $var ($self->installvars) { my $destvar = 'DESTINSTALL'.$var; $self->{$destvar} = $self->eliminate_macros($self->{$destvar}); } } =item init_DIRFILESEP No separator between a directory path and a filename on VMS. =cut sub init_DIRFILESEP { my($self) = shift; $self->{DIRFILESEP} = ''; return 1; } =item init_main (override) =cut sub init_main { my($self) = shift; $self->SUPER::init_main; $self->{DEFINE} \|\|= ''; if ($self->{DEFINE} ne '') { my(@terms) = split(/\s+/,$self->{DEFINE}); my(@defs,@udefs); foreach my $def (@terms) { next unless $def; my $targ = \@defs; if ($def =~ s/^-([DU])//) { # If it was a Unix-style definition $targ = \@udefs if $1 eq 'U'; $def =~ s/='(.)'$/=$1/; # then remove shell-protection '' $def =~ s/^'(.)'$/$1/; # from entire term or argument } if ($def =~ /=/) { $def =~ s/"/""/g; # Protect existing " from DCL $def = qq["$def"]; # and quote to prevent parsing of = } push @$targ, $def; } $self->{DEFINE} = ''; if (@defs) { $self->{DEFINE} = '/Define=(' . join(',',@defs) . ')'; } if (@udefs) { $self->{DEFINE} .= '/Undef=(' . join(',',@udefs) . ')'; } } } =item init_tools (override) Provide VMS-specific forms of various utility commands. Sets DEV_NULL to nothing because I don't know how to do it on VMS. Changes EQUALIZE_TIMESTAMP to set revision date of target file to one second later than source file, since MMK interprets precisely equal revision dates for a source and target file as a sign that the target needs to be updated. =cut sub init_tools { my($self) = @_; $self->{NOOP} = 'Continue'; $self->{NOECHO} \|\|= '@ '; $self->{MAKEFILE} \|\|= $self->{FIRST_MAKEFILE} \|\| 'Descrip.MMS'; $self->{FIRST_MAKEFILE} \|\|= $self->{MAKEFILE}; $self->{MAKE_APERL_FILE} \|\|= 'Makeaperl.MMS'; $self->{MAKEFILE_OLD} \|\|= $self->eliminate_macros('$(FIRST_MAKEFILE)_old'); # # If an extension is not specified, then MMS/MMK assumes an # an extension of .MMS.

=head1 NAME

ExtUtils::MM_VMS - methods to override UN*X behaviour in ExtUtils::MakeMaker

=head1 SYNOPSIS

Do not use this directly.
  Instead, use ExtUtils::MM and it will figure out which MM_*
  class to use for you.

=head1 DESCRIPTION

See ExtUtils::MM_Unix for a documentation of the methods provided
there. This package overrides the implementation of these methods, not
the semantics.

=item wraplist

Converts a list into a string wrapped at approximately 80 columns.

      # Perl bug -- seems to occasionally insert extra elements when
      # traversing array (scalar(@array) doesn't show them, but
      # foreach(@array) does) (5.00307)
      next unless $word =~ /\w/;

# This isn't really an override.  It's just here because ExtUtils::MM_VMS
# appears in @MM::ISA before ExtUtils::Liblist::Kid, so if there isn't an ext()
# in MM_VMS, then AUTOLOAD is called, and bad things happen.  So, we just
# mimic inheritance here and hand off to ExtUtils::Liblist::Kid.
# XXX This hackery will die soon. --Schwern

=head2 Methods

Those methods which override default MM_Unix methods are marked
"(override)", while methods unique to MM_VMS are marked "(specific)".
For overridden methods, documentation is limited to an explanation
of why this method overrides the MM_Unix method; see the ExtUtils::MM_Unix
documentation for more details.

=item guess_name (override)

Try to determine name of extension being built.  We begin with the name
of the current directory.  Since VMS filenames are case-insensitive,
however, we look for a F<.pm> file whose name matches that of the current
directory (presumably the 'main' F<.pm> file for this extension), and try
to find a C<package> statement from which to obtain the Mixed::Case
package name.

=item _fixin_replace_shebang (override)

Helper routine for MM->fixin(), overridden because there's no such thing as an
actual shebang line that will be interpreted by the shell, so we just prepend
$Config{startperl} and preserve the shebang line argument for any switches it
may contain.

=cut

=item maybe_command (override)

Follows VMS naming conventions for executable files.
If the name passed in doesn't exactly match an executable file,
appends F<.Exe> (or equivalent) to check for executable image, and F<.Com>
to check for DCL procedure.  If this fails, checks directories in DCL$PATH
and finally F<Sys$System:> for an executable file having the name specified,
with or without the F<.Exe>-equivalent suffix.

=cut

=item pasthru (override)

The list of macro definitions to be passed through must be specified using
the /MACRO qualifier and must not add another /DEFINE qualifier.  We prepend
our own comma here to the contents of $(PASTHRU_DEFINE) because it is often
empty and a comma always present in CCFLAGS would generate a missing
qualifier value error.

=item pm_to_blib (override)

VMS wants a dot in every file so we can't have one called 'pm_to_blib',
it becomes 'pm_to_blib.' and MMS/K isn't smart enough to know that when
you have a target called 'pm_to_blib' it should look for 'pm_to_blib.'.

So in VMS its pm_to_blib.ts.

=item fixpath

my $path = $mm->fixpath($path);
   my $path = $mm->fixpath($path, $is_dir);

Catchall routine to clean up problem MM[SK]/Make macros.  Expands macros
in any directory specification, in order to avoid juxtaposing two
VMS-syntax directories when MM[SK] is run.  Also expands expressions which
are all macro, so that we can tell how long the expansion is, and avoid
overrunning DCL's command buffer when MM[KS] is running.

fixpath() checks to see whether the result matches the name of a
directory in the current default directory and returns a directory or
file specification accordingly.  C<$is_dir> can be set to true to
force fixpath() to consider the path to be a directory or false to force
it to be a file.

NOTE:  This is the canonical version of the method.  The version in
File::Spec::VMS is deprecated.
