NAME

Template::Tiny - Template Toolkit reimplemented in as little code as possible

SYNOPSIS

  my $template = Template::Tiny->new(
      TRIM => 1,
  );
  
  # Print the template results to STDOUT
  $template->process( <<'END_TEMPLATE', { foo => 'World' } );
  Hello [% foo %]!
  END_TEMPLATE

DESCRIPTION

WARNING: THIS MODULE IS EXPERIMENTAL AND SUBJECT TO CHANGE WITHOUT NOTICE

YOU HAVE BEEN WARNED!

Template::Tiny is a reimplementation of a partial subset of the Template Toolkit in as few lines of code as possible.

It is intended for use in light-usage, low-memory, or low-cpu templating situations, where you may need to upgrade to the full feature set in the future, or if you want the familiarity of TT-style templates.

It is intended to have fully-compatible template and stash usage, with a limited by similar Perl API.

Unlike Template Toolkit, Template::Tiny will process templates without a compile phase (but despite this is still quicker, owing to heavy use of the Perl regular expression engine.

SUPPORTED USAGE

Only the default [% %] tag style is supported.

Both the [%+ +%] style explicit whitespace and the [%- -%] style explicit chomp are support, although the [%+ +%] version is unneeded as Template::Tiny does not support default-enabled PRE_CHOMP or POST_CHOMP.

Variable expressions in the form foo.bar.baz are supported.

Appropriate simple behaviours for ARRAY reference, HASH reference and objects are supported, but not "VMethods" such as array lengths.

IF, ELSE and UNLESS conditions are supported, but only with simple foo.bar.baz conditions.

Support for looping is available, in the most simple [% FOREACH item IN list %] form.

All four IF/ELSE/UNLESS/FOREACH control structures are able to be nested to arbitrary depth.

The treatment of _private hash and method keys is compatible with Template Toolkit, returning null or false rather than the actual content of the hash key or method.

Anything beyond this is currently out of scope

METHODS

new

  my $template = Template::Tiny->new(
      TRIM => 1,
  );

The new constructor is provided for compatibility with Template Toolkit.

The only parameter it currently supports is TRIM (which removes leading and trailing whitespace from processed templates).

Additional parameters can be provided without error, but will be ignored.

process

  # DEPRECATED: Return template results
  my $text = $template->process( \$input, $vars );
  
  # Print template results to STDOUT
  $template->process( \$input, $vars );
  
  # Generate template results into a variable
  my $output = '';
  $template->process( \$input, $vars, \$output );

The process method is called to process a template.

The first parameter is a reference to a text string containing the template text. A reference to a hash may be passed as the second parameter containing definitions of template variables.

If a third parameter is provided, it must be a scalar reference to be populated with the output of the template.

For a limited amount of time, the old deprecated interface will continue to be supported. If process is called without a third parameter, and in scalar or list contest, the template results will be returned to the caller.

If process is called without a third parameter, and in void context, the template results will be print()ed to the currently selected file handle (probably STDOUT) for compatibility with Template.
