NAME

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

VERSION

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

SYNOPSIS

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;

DESCRIPTION

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.

INHERITED METHODS

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.

CLASS METHODS

$obj = $class->new(%parameters)

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.

INSTANCE METHODS

$obj->archive

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

DIAGNOSTICS

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).

CONFIGURATION AND ENVIRONMENT

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

DEPENDENCIES

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

INCOMPATIBILITIES

None reported.
