NAME

       Text::MicroTemplate - Micro template engine with Perl5 language

SYNOPSIS

	   use Text::MicroTemplate qw(:all);

	   # compile template, and render
	   $renderer = build_mt('hello, <?= $_[0] ?>');
	   $html = $renderer->('John')->as_string;

	   # or in one line
	   $html = render_mt('hello, <?= $_[0] ?>', 'John')->as_string;

	   # complex form
	   $mt = Text::MicroTemplate->new(
	       template => 'hello, <?= $query->param('user') ?>',
	   );
	   $code = $mt->code;
	   $renderer = eval << "..." or die $@;
	   sub {
	       my $query = shift;
	       $code->();
	   }
	   ...
	   $html = $renderer->(CGI->new)->as_string;

DESCRIPTION

       Text::MicroTemplate is a standalone, fast, intelligent, extensible template engine with following features.

   standalone
       Text::MicroTemplate does not rely on other CPAN modules.

   fast
       Based on Mojo::Template, expressions in the template is perl code.

   intelligent
       Text::MicroTemplate automatically escapes variables when and only when necessary.

   extensible
       Text::MicroTemplate does not provide features like template cache or including other files by itself.  However, it is easy to add you own
       (that suites the most to your application), by wrapping the result of the module (which is a perl expression).

       The module only provides basic building blocks for a template engine.  Refer to Text::MicroTemplate::File for higher-level interface.

TEMPLATE SYNTAX

       The template language is Perl5 itself!

	   # output the result of expression with automatic escape
	   <?= $expr ?> 	    (tag style)
	   ?= $expr		    (per-line)

	   # execute perl code (tag style)
	   <? foo() ?>
	   ? foo()

	   # comment (tag style)
	   <?# comment ?>
	   ?# comment

	   # loops
	   <ul>
	   ? for my $item (@list) {
	   <li><?= $item ?></li>
	   ? }
	   </ul>

EXPORTABLE FUNCTIONS

   build_mt($template)
       Returns a subref that renders given template.  Parameters are equivalent to Text::MicroTemplate->new.

	   # build template renderer at startup time and use it multiple times
	   my $renderer = build_mt('hello, <?= $_[0] ?>!');

	   sub run {
	       ...
	       my $hello = $renderer->($query->param('user'));
	       ...
	   }

   render_mt($template, @args)
       Utility function that combines build_mt and call to the generated template builder.

	   # render
	   $hello = render_mt('hello, <?= $_[0] ?>!', 'John');

	   # print as HTML
	   print $hello->as_string;

	   # use the result in another template (no double-escapes)
	   $enc = render_mt('<h1><?= $_[0] ?></h1>', $hello);

       Intertally, the function is equivalent to:

	   build_mt($template)->(@_);

   encoded_string($str)
       wraps given string to an object that will not be escaped by the template engine

OO-STYLE INTERFACE
       Text::MicroTemplate provides OO-style interface to handle more complex cases.

   new($template)
   new(%args)
   new(\%args)
       Constructs template renderer.  In the second or third form, parameters below are recognized.

       template

       template string (mandatory)

       escape_func

       escape function (defaults to Text::MicroTemplate::escape_html), no escape when set to undef

       package_name

       package under where the renderer is compiled (defaults to caller package)

   code()
       returns perl code that renders the template when evaluated

   filter(sub filter_func { ... })->(sub { template lines })
       filters given template lines

	   ? $_mt->filter(sub { s/Hello/Good bye/g })->(sub {
	   Hello, John!
	   ? })

DEBUG

       The "MICRO_TEMPLATE_DEBUG" environment variable helps debugging.  The value 1 extends debugging messages, 2 reports compiled Perl code with
       "warn()", 3 is like 2 but uses "die()".
