NAME

Text::MicroMason::TemplateDir - Use Base Directory and Relative Paths

SYNOPSIS

Instead of using this class directly, pass its name to be mixed in:

    use Text::MicroMason;
    my $mason = Text::MicroMason->new( -TemplateDir, template_root=>'/foo' );

Use the standard compile and execute methods to parse and evaluate templates:

  print $mason->compile( file=>$filepath )->( 'name'=>'Dave' );
  print $mason->execute( file=>$filepath, 'name'=>'Dave' );

Templates stored in files are looked up relative to the template root:

    print $mason->execute( file=>"includes/greeting.msn", 'name'=>'Charles');

When including other files into a template you can use relative paths:

    <& ../includes/greeting.msn, name => 'Alice' &>

DESCRIPTION

This module changes the resolution of files passed to compile() and execute() to be relative to a base directory path or to the currently executing template.

Supported Attributes

template_root

Base directory from which to find templates.

strict_root

Optional directory beyond which not to read files. If set to 1, uses template_root, Causes read_file to croak if any filename outside of the root is provided. (Note that this is not a chroot jail and only affects attempts to load a file as a template; for greater security see the chroot() builtin and Text::MicroMason::Safe.)

Private Methods

prepare

Intercepts uses of file templates and applies the base-path adjustment.

read_file

Intercepts file access to check for strict_root.

EXCEPTIONS

The following additional exceptions are generated by Text::MicroMason::TemplateDir when appropriate:

  • Text::MicroMason::TemplateDir: Strict root '%s' doesn't seem to exist

    The strict_root directory (or template_root if strict_root is '1') doesn't seem to exist. Strict root checking uses Cwd's abs_path(), and requires the strict_root directory to exist at the time the check is performed.

  • Text::MicroMason::TemplatePath: Template '%s' not in required base path '%s'

    The template found in the configured template path was not within the configured strict_root directory. This may be caused by requesting an absolute template filename not within strict_root, or by specifying a strict_root which does not match the configured template path.
