+
+Module::Build::Platform::VMS - Builder class for VMS platforms
+
+=head1 DESCRIPTION
+
+This module inherits from C<Module::Build::Base> and alters a few
+minor details of its functionality. Please see L<Module::Build> for
+the general docs.
+
+=head2 Overridden Methods
+
+=over 4
+
+=item _set_defaults
+
+Change $self->{build_script} to 'Build.com' so @Build works.
+
+=cut
+
+sub _set_defaults {
+ my $self = shift;
+ $self->SUPER::_set_defaults(@_);
+
+ $self->{properties}{build_script} = 'Build.com';
+}
+
+
+=item cull_args
+
+'@Build foo' on VMS will not preserve the case of 'foo'. Rather than forcing
+people to write '@Build "foo"' we'll dispatch case-insensitively.
+
+=cut
+
+sub cull_args {
+ my $self = shift;
+ my($action, $args) = $self->SUPER::cull_args(@_);
+ my @possible_actions = grep { lc $_ eq lc $action } $self->known_actions;
+
+ die "Ambiguous action '$action'. Could be one of @possible_actions"
+ if @possible_actions > 1;
+
+ return ($possible_actions[0], $args);
+}
+
+
+=item manpage_separator
+
+Use '__' instead of '::'.
+
+=cut
+
+sub manpage_separator {
+ return '__';
+}
+
+
+=item prefixify
+
+Prefixify taking into account VMS' filepath syntax.
+
+=cut
+
+# Translated from ExtUtils::MM_VMS::prefixify()
+sub _prefixify {
+ my($self, $path, $sprefix, $type) = @_;

+ $sprefix = VMS::Filespec::vmspath($sprefix) if $sprefix;
+

+ " sprefix translated to $sprefix\n");
+

+}
+
+=item _quote_args
+
+Command-line arguments (but not the command itself) must be quoted
+to ensure case preservation.
+
+=cut
+
+sub _quote_args {
+ # Returns a string that can become [part of] a command line with
+ # proper quoting so that the subprocess sees this same list of args,
+ # or if we get a single arg that is an array reference, quote the
+ # elements of it and return the reference.
+ my ($self, @args) = @_;
+ my $got_arrayref = (scalar(@args) == 1

+ : @args
+ );
+
+ return $got_arrayref ? $args[0]
+ : join(' ', @args);
+}
+
+=item have_forkpipe
+
+There is no native fork(), so some constructs depending on it are not
+available.
+
+=cut
+
+sub have_forkpipe { 0 }
+
+=item _backticks
+
+Override to ensure that we quote the arguments but not the command.
+
+=cut
+
+sub _backticks {
+ # The command must not be quoted but the arguments to it must be.
+ my ($self, @cmd) = @_;
+ my $cmd = shift @cmd;
+ my $args = $self->_quote_args(@cmd);

+Override to ensure that we quote the arguments but not the command.

+=cut

+ my $cmd = shift @cmd;
+ my $args = $self->_quote_args(@cmd);
+ return !system("$cmd $args");
+}
+
+=item _infer_xs_spec
+
+Inherit the standard version but tweak the library file name to be
+something Dynaloader can find.
+
+=cut
+
+sub _infer_xs_spec {
+ my $self = shift;
+ my $file = shift;
+
+ my $spec = $self->SUPER::_infer_xs_spec($file);
+
+ # Need to create with the same name as DynaLoader will load with.

+ $file = DynaLoader::mod2fname([$file]);
+ $$spec{lib_file} = File::Spec->catfile($$spec{archdir}, $file);
+ }
+
+ return $spec;
+}
+
+=item rscan_dir
+
+Inherit the standard version but remove dots at end of name. This may not be
+necessary if File::Find has been fixed or DECC$FILENAME_UNIX_REPORT is in effect.
+
+=cut
+
+sub rscan_dir {
+ my ($self, $dir, $pattern) = @_;
+
+ my $result = $self->SUPER::rscan_dir( $dir, $pattern );
+
+ for my $file (@$result) { $file =~ s/\.$//; }
+ return $result;
+}
+
+=item dist_dir
+
+Inherit the standard version but replace embedded dots with underscores because
+a dot is the directory delimiter on VMS.
+
+=cut
+
+sub dist_dir {
+ my $self = shift;
+
+ my $dist_dir = $self->SUPER::dist_dir;
+ $dist_dir =~ s/\./_/g;
+ return $dist_dir;
+}
+
+=item man3page_name
+
+Inherit the standard version but chop the extra manpage delimiter off the front if
+there is one. The VMS version of splitdir('[.foo]') returns '', 'foo'.
+
+=cut
+
+sub man3page_name {
+ my $self = shift;
+
+ my $mpname = $self->SUPER::man3page_name( shift );
+ my $sep = $self->manpage_separator;
+ $mpname =~ s/^$sep//;
+ return $mpname;
+}
+
+=item expand_test_dir
+
+Inherit the standard version but relativize the paths as the native glob() doesn't
+do that for us.
+
+=cut
+
+sub expand_test_dir {
+ my ($self, $dir) = @_;
+
+ my @reldirs = $self->SUPER::expand_test_dir( $dir );
+

+ $eachdir = File::Spec->catfile( $reldir, $f );
+ }
+ return @reldirs;
+}
+
+=item _detildefy
+
+The home-grown glob() does not currently handle tildes, so provide limited support
+here. Expect only UNIX format file specifications for now.
+
+=cut
+
+sub _detildefy {
+ my ($self, $arg) = @_;
+
+ # Apparently double ~ are not translated.
+ return $arg if ($arg =~ /^~~/);
+
+ # Apparently ~ followed by whitespace are not translated.

+ # Trivial case of just ~ by it self

+ }
+
+ my ($hvol, $hdir, $hfile) = File::Spec::Unix->splitpath($home);
+ if ($hdir eq '') {
+ # Someone has tampered with $ENV{HOME}
+ # So hfile is probably the directory since this should be
+ # a path.

+ # Simple case, just merge together
+ $newdirs = File::Spec::Unix->catdir(@hdirs, @dirs);
+
+ } else {
+
+ # Complex case, need to add an updir - No delimiters
+ my @backup = File::Spec::Unix->splitdir(File::Spec::Unix->updir);
+
+ $newdirs = File::Spec::Unix->catdir(@hdirs, @backup, @dirs);
+

+ $arg = File::Spec::Unix->catpath($hvol, $newdirs, $file);
+
+ } else {
+ return $arg;
+ }
+
+}
+
+=item find_perl_interpreter
+
+On VMS, $^X returns the fully qualified absolute path including version
+number. It's logically impossible to improve on it for getting the perl
+we're currently running, and attempting to manipulate it is usually
+lossy.
+
