Template::Tiny(3) User Contributed Perl Documentation Template::Tiny(3)NAMETemplate::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
DESCRIPTIONTemplate::Tiny is a reimplementation of a subset of the functionality
from 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 retain the familiarity of
TT-style templates.
For the subset of functionality it implements, it has fully-compatible
template and stash API. All templates used with Template::Tiny should
be able to be transparently upgraded to full Template Toolkit.
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
in practice 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" references, "HASH" references
and objects are supported. "VMethods" such as [% array.length %] are
not supported at this time.
"IF", "ELSE" and "UNLESS" conditional blocks are supported, but only
with simple "[% foo.bar.baz %]" conditions.
Support for looping (or rather iteration) is available in simple "[%
FOREACH item IN list %]" form is supported. Other loop structures are
not supported. Because support for arbitrary or infinite looping is not
available, Template::Tiny templates are not turing complete. This is
intentional.
All of the four supported control structures
"IF"/"ELSE"/"UNLESS"/"FOREACH" can 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 the above 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 (emits a warning)
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.
