NAME
    Solution - A Simple, Stateless Template System

Synopsis
        use Solution;
        my $template = Solution::Template->new();
        $template->parse(    # See Solution::Tag for more examples
              '{% for x in (1..3) reversed %}{{ x }}, {% endfor %}{{ some.text }}'
        );
        print $template->render({some => {text => 'Contact!'}}); # 3, 2, 1, Contact!

Description
    Solution is a template engine based on Liquid. The Liquid template
    engine was crafted for very specific requirements:

    *   It has to have simple markup and beautiful results. Template engines
        which don't produce good looking results are no fun to use.

    *   It needs to be non-evaling and secure. Liquid templates are made so
        that users can edit them. You don't want to run code on your server
        which your users wrote.

    *   It has to be stateless. The compile and render steps have to be
        separate, so that the expensive parsing and compiling can be done
        once; later on, you can just render it by passing in a hash with
        local variables and objects.

    *   It needs to be able to style emails as well as HTML.

Getting Started
    It's very simple to get started with Solution. Just as in Liquid,
    templates are built and used in two steps: Parse and Render.

        my $sol = Solution::Template->new();  # Create a Solution::Template object
        $sol->parse('Hi, {{name}}!');         # Parse and compile the template
        $sol->render({name => 'Sanko'});      # Render the output => "Hi, Sanko!"

        # Or if you're in a hurry...
        Solution::Template->parse('Hi, {{name}}!')->render({name => 'Sanko'});

    The "parse" step creates a fully compiled template which can be re-used
    as often as you like. You can store it in memory or in a cache for
    faster rendering later.

    All parameters you want Solution to work with have to be passed as
    parameters to the "render" method. Solution is a closed ecosystem; it
    does not know about your local, instance, global, or environment
    variables.

    For an expanded overview of the Liquid/Solution syntax, please see
    Solution::Tag and read Liquid for Designers
    <http://wiki.github.com/tobi/liquid/liquid-for-designers>.

Extending Solution
    Extending the Solution template engine for your needs is almost too
    simple. Keep reading.

  Custom Filters
    Filters are simple subs called when needed. They are not passed any
    state data by design and must return the modified content.

    TODO: I need to write Solution::Filter which will be POD with all sorts
    of info in it. Yeah.

   "Solution->register_filter( ... )"
    This registers a package which Solution will assume contains one or more
    filters.

        # Register a package as a filter
        Solution->register_filter( 'SolutionX::Filter::Amalgamut' );

        # Or simply say...
        Solution->register_filter( );
        # ...and Solution will assume the filters are in the calling package

   "Solution->filters( )"
    Returns a list containing all the tags currently loaded for
    informational purposes.

  Custom Tags
    See the section entitled Extending Solution with Custom Tags in
    Solution::Tag for more information.

    To assist with custom tag creation, Solution provides several basic tag
    types for subclassing and exposes the following methods:

   "Solution->register_tag( ... )"
    This registers a package which must contain (directly or through
    inheritance) both a "parse" and "render" method.

        # Register a new tag which Solution will look for in the given package
        Solution->register_tag( 'newtag', 'SolutionX::Tag::You're::It' );

        # Or simply say...
        Solution->register_tag( 'newtag' );
        # ...and Solution will assume the new tag is in the calling package

    Pre-existing tags are replaced when new tags are registered with the
    same name. You may want to do this to override some functionality.

   "Solution->tags( )"
    Returns a hashref containing all the tags currently loaded for
    informational purposes.

Why should I use Solution?
    *   You want to allow your users to edit the appearance of your
        application, but don't want them to run insecure code on your
        server.

    *   You want to render templates directly from the database.

    *   You like Smarty-style template engines.

    *   You need a template engine which does HTML just as well as email.

    *   You don't like the markup language of your current template engine.

    *   You wasted three days reinventing this wheel when you could have
        been doing something productive like volunteering or catching up on
        past seasons of *Doctor Who*.

Why shouldn't I use Solution?
    *   You've found or written a template engine which fills your needs
        better than Liquid or Solution ever could.

    *   You are uncomfortable with text that you didn't copy and paste
        yourself. Everyone knows computers cannot be trusted.

'Solution to what?' or 'Ugh! Why a new Top Level Namespace?'
    I really don't have a good reason for claiming a new top level namespace
    and I promise to put myself in timeout as punishment.

    As I understand it, the original project's name, Liquid, is a reference
    to the classical states of matter (the engine itself being stateless). I
    settled on Solution <http://en.wikipedia.org/wiki/Solution> because it's
    Liquid but... with... bits of other stuff floating in it. Pretend you
    majored in chemistry instead of mathematics or computer science and
    you'll know what I mean.

    This 'solution' is not the answer to all your problems and obviously not
    the only solution for your templating troubles. It's simply *a*
    solution.
