# NAME

Text::MustacheTemplate - mustache template engine

# SYNOPSIS

    use Text::MustacheTemplate;
    # local $Text::MustacheTemplate::OPEN_DELIMITER = '<%';
    # local $Text::MustacheTemplate::CLOSE_DELIMITER = '%>';

    my $rendered = Text::MustacheTemplate->render('* {{variable}}', { variable => 'foo' }); # => "* foo"

    my $template = Text::MustacheTemplate->parse('* {{variable}}');
    $rendered = $template->({ variable => 'foo' }); # => "* foo"
    $rendered = $template->({ variable => 'bar' }); # => "* bar"

# DESCRIPTION

Text::MustacheTemplate is [mustache](https://mustache.github.io/) template engine written in Pure Perl.

All features of Mustache Template are implemented. (e.g. inheritance, lambda, etc..)
And it is passed all [mustache/spec](https://github.com/mustache/spec) test cases.

# METHODS

- parse

    Parses the template text. Returns a subroutine reference.
    The subroutine receives one argument and processes the parsed template using the context variable specified in the argument.

        my $template = Text::MustacheTemplate->parse('* {{variable}}');
        $rendered = $template->({ variable => 'foo' }); # => "* foo"

    This method is suitable for rendering the same template multiple times.

- render

    Render the template text using the context.
    It returns a rendered text. 

        my $rendered_text = Text::MustacheTemplate->render($template_text, $context);

    This method is suitable when the same template is rarely used.

# VARIABLES

Text::MustacheTemplate changes its behavior according to the following variables.
By using `local`, this change can be localized.

- $OPEN\_DELIMITER

    This is the delimiter that opens the tag.
    The default value is `"{{"`.

- $CLOSE\_DELIMITER

    This is the delimiter that closes the tag.
    The default value is `"}}"`.

- %REFERENCES

    This is references to other parsed templates.
    It's used by inheritance or partial template feature.

- $LAMBDA\_TEMPLATE\_RENDERING

    When this flag is truthy, lambda template rendering is enabled.
    The default value is falsey.
