Template::Provider::PAR - Include templates from a path within a PAR or Zip archive.

This document describes Template::Provider::PAR version 0.1.102.

    use Template;
    use Template::Provider::PAR;

    # Specify the provider in the config for Template::Toolkit.  Note,
    # since no archive name is specified here, the name of the archive
    # will be obtained from $0
    my $tt_config =
    {
        LOAD_TEMPLATES =>
        [Template::Provider::PAR->new(INCLUDE_PATH => 'some/archive/dir')]
    };

    my $template = <<TEMPLATE;
    [% PROCESS something_in_the_archive.tt %]
    TEMPLATE

    my $tt = Template->new($tt_config);
    $tt->process($template, $vars) || die $tt->error;

This Template::Provider::PAR is designed to behave like a regular Template::Provider, except that it retrieves templates from a path in a PAR archive, by default the archive in which the running script is embedded within.

This allows Template::Toolkit to be used from an entirely self-contained PAR archive.

These methods are inherited from Template::Provider and function in exactly the same way:

* fetch()

* store()

* load()

* include_path()

* paths()

* DESTROY()

See Template::Provider for details of these methods.

Constructs a new instance.

Accepts all the arguments as for the base class Template::Provider, with the following additions:

ARCHIVE

This optional parameter explicity sets the archive to use, either as a filename or a reference to a Archive::Zip object. If omitted, then the return value of PAR::par_handle($0) is used. If this returns undef, an error is thrown.

INCLUDE_PATH

This works as before, except obviously it refers to a path within the archive.

Note that the RELATIVE parameter makes no sense within a PAR archive, as it has no concept of a current directory, so the behaviour is currently undefined and it should not be used.

Returns a reference to the PAR archive (an instance of Archive::Zip).

Template, Template::Provider, PAR, Archive::Zip

In addition to errors raised by Template::Provider and DBIx::Class, Template::Provider::PAR may generate the following error messages:

Archive '$archive' does not exist

Thrown by the constructor if the ARCHIVE paramter is a non-existant filename.

ARCHIVE parameter is not an Archive::Zip instance

Thrown by the constructor if the ARCHIVE paramter references an object which isn't an Archive::Zip instance.

As we do not seem to be used within a PAR archive you must define the ARCHIVE parameter to reference a Zip archive

Thown by the constructor if no ARCHIVE parameter is defined and the host archive can't be inferred (i.e. if the running script is not packaged within a PAR archive).

Template::Provider::PAR requires no configuration files or environment variables, other than those set by PAR's runtime environment.

Archive::Zip

PAR

Scalar::Util

File::Spec

Carp

Template::Provider

Module::Build

Test::More

Additionally, use of this module requires an object of the class DBIx::Class::Schema or DBIx::Class::ResultSet.
