"Cutout" templating system concept.
This project represents the first take on yet another logicless templating system named "Cutout". Main idea behind Cutout system, is to enable a programmer to program template logic in his favorite programming language.
Firstly, we takes template prototype, say, simple .html file.
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8"/>
<title></title>
</head>
<body>
<header>
<h1></h1>
<nav>
<ul>
<li>
<a href=""></a>
</li>
</ul>
</nav>
<span class="warning">session timeout</span>
<span class="warning">we don't support your client, sorry</span>
<span class="error">oops...</span>
</header>
<main>
</main>
<footer>
<small></small>
</footer>
</body>
</html>Next, we "cut" it to parts and "mark" injection points.
<!DOCTYPE html>
<html>
<head>
{?head}
<meta charset="UTF-8"/>
<title>{title}</title>
{/head}
</head>
<body>
{?body}
<header>
<h1>{heading}</h1>
<nav>
{?navigation}
<ul>
{?links}
<li>
<a href="{href}">{text}</a>
</li>
{/links}
</ul>
{/navigation}
</nav>
{?status}
{?timeout}<span class="warning">session timeout</span>{/timeout}
{?client_unsupported}<span class="warning">we don't support your client, sorry</span>{/client_unsupported}
{?error}<span class="error">oops...</span>{/error}
{/status}
</header>
<main>
{?content}{/content}
</main>
<footer>
{?footer}
<small>{copyright}</small>
{/footer}
</footer>
{/body}
</body>
</html>"Cut" syntax contains open and close tags, like {?head} and {/head} in example above. The "head" string in these tags defines a name of the "cut". Everything between "cut" tags is treated as nested template.
"Mark" syntax contains one tag, like {title} in example above. The "title" string in this tag defines a name of the "mark". Additionally, "mark" name may be followed by equal sign (=) and default string value.
After that we generate code for target programming language.
In general we get a template function for each template. We must provide arguments for each unique mark name and cut name to to get rendering function. Then we may use renderig function to render resulting text.
Actual implementation for concrete programming language or platform may has additional features and/or constraints.
