Template Toolkit

ПРЕДУПРЕЖДЕНИЕ: Это неполная, устаревшая и неточная документация. Библиотека Splash! находится в стадии разработки и изменения. Смотрите примеры, чтобы получить более точное и новое представление об использовании библиотеки.

Библиотека шаблонов 'Splash' поставляется в составе Template Toolkit. Ее можно найти в подкаталоге 'templates' установочного каталога.

Перед использованием библиотеки Splash необходимо сообщить Template Toolkit где искать файлы шаблонов.

    use Template;

    my $tt2 = Template->new({
	INCLUDE_PATH => '/usr/local/tt2/templates',
    });

Для переносимости можно использовать метод класса 'Template::Config->instdir()', чтобы определить каталог, в который установлена библиотека 'templates'.

    use Template;

    my $tt2 = Template->new({
	INCLUDE_PATH => Template::Config->instdir('templates'),
    });

Обратите внимание, что в INCLUDE_PATH должен быть установлен каталог 'templates', как показано выше, а не каталог 'templates/splash', как вы можете захотеть сделать. Многие из компонентов Splash! используют элементы в каталоге 'html' и содержать директивы такого вида:

    [% INCLUDE html/something %].

The 'splash/config' template defines a 'splash' hash array which contains numerous configuration items for the Splash library. You must PROCESS this template to ensure that the hash definition is imported into your calling template. An INCLUDE is not sufficient as it localises variables and prevents the 'splash' hash array from existing outside the splash/config template.

    [% PROCESS splash/config %]

Alternately, you can define the splash/config template as a PRE_PROCESS item when you create the Template processor.

    use Template;

    my $tt2 = Template->new({
	INCLUDE_PATH => Template::Config->instdir('templates'),
	PRE_PROCESS  => 'splash/config',
    });

You can modify the default configuration by creating your own PRE_PROCESS config file which loads the 'splash/config' and then tweaks the settings to your own preferences.

    my $tt2 = Template->new({
	INCLUDE_PATH => [ '/home/abw/tt2/templates',
		          Template::Config->instdir('templates') ],
        PRE_PROCESS => 'config'
    });

/home/abw/tt2/templates/config:

    [% # load the 'splash' configuration
       PROCESS splash/config;

       # tweak values to personal preferences
       splash.images       = '/~abw/tt2/images/splash'
       splash.select.col   = 'leaf'
       splash.unselect.col = 'bud'
    %]

The splash/config file includes some instructional comments on things you might like to tweak.

The Splash! library uses the colours defined in the html/rgb template. The 'rgb' hash defined therein is imported as the 'splash.rgb' hash.

    [% INCLUDE splash/box col='grey75' %]

See the examples for further enlightenment on using colour.

There are two very primitive "styles" implemented called "select" and "unselect". These are used to indicate which item on a menu is selected, for example. Each style defines characteristics like background colour, font face, size and colour, text alignment, and so on.

The styles are implemented as hashes within the 'splash' hash. Many of the components respond to a 'style' variable being set and you can pass a direct reference to splash.select or splash.unselect (or your own styles). e.g.

    [% INCLUDE splash/button
	   content = "Unselected"
           style   = splash.unselect
    %]
    [% INCLUDE splash/button
           content ="Selected"
           style   = splash.select
    %]

Alternately, you can use the 'select' variable to indicate either of the inbuilt styles: splash.select or splash.unselect.

    [% INCLUDE splash/button
           content = "Unselected"
           select  = 0
    %]
    [% INCLUDE splash/button
           content = "Selected"
           select  = 1
    %]

This section describes some of the component templates in the Splash! library. This documentation is incomplete and may also be inaccurate in places. The examples in the 'examples' directory are likely to be a much better reference.
