Template::Stash::XS(3)

NAME
Template::Stash::XS - Experimetal high-speed stash written in XS

SYNOPSIS
    use Template;
    use Template::Stash::XS;

    my $stash = Template::Stash::XS->new(\%vars);
    my $tt2   = Template->new({ STASH => $stash });

DESCRIPTION
This module loads the XS version of Template::Stash::XS. It should behave very much like the old one, but run about twice as fast. See the synopsis above for usage information.

Only a few methods (such as get and set) have been implemented in XS. The others are inherited from Template::Stash.

NOTE
To always use the XS version of Stash, modify the Template/Config.pm module near line 45:

 $STASH    = 'Template::Stash::XS';

If you make this change, then there is no need to explicitly create an instance of Template::Stash::XS as seen in the SYNOPSIS above. Just use Template as normal.

Alternatively, in your code add this line before creating a Template object:

 $Template::Config::STASH = 'Template::Stash::XS';

To use the original, pure-perl version restore this line in Template/Config.pm:

 $STASH    = 'Template::Stash';

Or in your code:

 $Template::Config::STASH = 'Template::Stash';

You can elect to have this performed once for you at installation time by answering 'y' or 'n' to the question that asks if you want to make the XS Stash the default.

BUGS
Please report bugs to the Template Toolkit mailing list templates@template-toolkit.org

As of version 2.05 of the Template Toolkit, use of the XS Stash is known to have 2 potentially troublesome side effects. The first problem is that accesses to tied hashes (e.g. Apache::Session) may not work as expected. This should be fixed in an imminent release. If you are using tied hashes then it is suggested that you use the regular Stash by default, or write a thin wrapper around your tied hashes to enable the XS Stash to access items via regular method calls.

The second potential problem is that enabling the XS Stash causes all the Template Toolkit modules to be installed in an architecture dependant library, e.g. in

    /usr/lib/perl5/site_perl/5.6.0/i386-linux/Template

instead of

    /usr/lib/perl5/site_perl/5.6.0/Template

At the time of writing, we're not sure why this is happening but it's likely that this is either a bug or intentional feature in the Perl ExtUtils::MakeMaker module. As far as I know, Perl always checks the architecture dependant directories before the architecture independant ones. Therefore, a newer version of the Template Toolkit installed with the XS Stash enabled should be used by Perl in preference to any existing version using the regular stash. However, if you install a future version of the Template Toolkit with the XS Stash disabled, you may find that Perl continues to use the older version with XS Stash enabled in preference.
