NAME

Markapl - Markup as Perl

VERSION

This document describes Markapl version 0.03

SYNOPSIS

    package MyView;
    use Markapl;

    tempalte '/a/page.html' => sub {
        h1("#title") { "Hi" };
        p(".first") { "In the begining, lorem ipsum...." };
        p(style => "color: red;") { "But...." };
    }

    package main;
    my $output = MyView->render("/a/page.html");

TUTORIAL

Here's a short guide how to use this module. You can skip this tutorial section if you're already using Template::Declare, since it's exactly the same.

First of all, you need a sole package for defining your tempaltes, let's call it "MyView" in the example. Then you use Markapl (but not use base), then your view package will be installed many subroutines automatically:

    package MyView;
    use Markapl;

To define a template, use template function like this:

    tempalte '/page.html' => sub {
        h1("#title") { "Hi" };
        p(".first") { "In the begining, lorem ipsum...." };
        p(style => "color: red;") { "But...." };
    }

To render it, call render function:

    my $out = MyView->render("/page.html");

Besides these two functions, Markapl also exports about another 120 tag functions that are named after HTML tags, for exapmle, h1, h2, h3, div, p, and span. Almost all HTML tags are defined as a function.

In your template, if you say:

    h1 { "Hi" };

It'll be rendered as:

    <h1>Hi</h1>

The block after h1 is an anonymous sub-routine, and the return value of which will become the content of the h1 tag.

If you want to add attributes to the tag, do it like this:

    div(id => "example", class => "lipsum") { "Lorem ipsum" };

Alternatively, you can use CSS selector syntax to quickly defined id and class attribute:

    div("#example") { "Lorem ipsum" };

That only works when the attribute list contain excatly one string inside.

A special function outs need to be used to concatinate strings with inline elements:

    p {
        outs "Hello, ";
        a(href => "/users/gugod") { "gugod" };
    }

DESCRIPTION

This is a new try to use Devel::Declare to change the Perl5 language. It learns pretty much everything from Tempalte::Declare, and has similar interface. With only one difference: how element attributes are defined.

In Template::Declare, it goes like:

    h1 {
        id is "title";
        outs "Hi";
    };

In here, it is:

    h1(id => "title") { "Hi" };

Or a shorthand for "id" attribute:

    h1("#title") { "Hi" };

INTERFACE

template($name, $code);

Defines a template.

render($name)

You need to call it as class method like,

   MyView->render("/foo.html");

Or

   render MyView, "/foo.html";

If you happen to like this style.

Doesn't support tempalte variable yet. Stay tuned.

outs($str);

Should be used in side a template body. It appends $str to current output buffer frame.
