1. Multi-line actions and formatters

The main goal is that the user can move each argument on a own line for better readability.

• info boxes
• content templates

These are the two favorite ways to expand the markup rules. Among other things, the use of these methods does not require a detailed analysis of the initial class of the Wacko formatter.

So you can write your own actions or a dedicated formatter which parses your predefined syntax.

1. {{tpl_name param... }}
2. %%(tpl param... ) content%%

Thus, whether you chose a action or a formatter, depends on the necessity to have methods for combining static and dynamic data, such as database queries, or not.

• WackoWiki Markup

To make this approach expandable to whatever you like we just should treat wiki-pages as data objects.
Then one can use as I have mentioned before or any other kind of a new tool to work with such objects.
We have already page_lang VARCHAR(5) in pages table - to set language, and formatting VARCHAR(20) that can be used to say that some pages are not ordinary wiki-pages but "data objects".
This requires some changes to catalog, revisions, history tracking tools etc. -- Elar9000

2. How to write your own content templates.

Very simple example without advanced array usage, functions, styles or filters.

2.1. Action

This action has no dynamic data, it serves here only as a example in comparison to the formatter below. Usually you don't want use a action for only static data.

{{tpl_movie
	title="A Civil Action"
	image="a_civil_action_poster.jpg"
	author="Jonathan Harr"
	country="United States"
	language="English"
	published="1998-12-25"
	runtime="115 minutes"
	starring= ...
}}	

action/tpl_movie.php

<?php

if (!defined('IN_WACKO'))
{
    exit;
}

$info = <<<EOD
Description:
    Displays a movie info box.

Usage:
    {{movie
        title="The Movie Title"
        image="movie_poster.jpg"

        country="Country"
        language="Language"
        published="2022-02-25"
        runtime="120 minutes"
        starring= ...
    }}
EOD;

//  set defaults

$author        ??= '';
$country    ??= '';
$language    ??= '';
$published    ??= '';
$runtime    ??= '';
// ...

if ($help)
{
    $tpl->help    = $this->help($info, 'tpl_movie');
    return;
}

// args


// display movie infobox
{
    $tpl->enter('m_');

    // $tpl->var    = $var or function with $var;
    $tpl->title        = $title;
    $tpl->image        = $this->link('file:/' . $image, '', $text);

    $tpl->country    = $country;
    $tpl->language    = $language;
    $tpl->published    = $published;
    $tpl->runtime    = $runtime;
    // ...

    // include another action
    # $tpl->include        = $this->action('tpl_' . $name, $param);

    $tpl->leave(); // m_
