Template::Library::Splash - Template library for building stylish HTML user interfaces
NOTE: This documentation is incomplete, incorrect and outdated. The Splash! library is still evolving and subject to change. See the examples for a much more recent and accurate demonstration of use.
The 'Splash' template library is distributed as part of the Template Toolkit. It can be found in the 'templates' sub-directory of the installation directory.

To use the Splash library, you first need to tell the Template Toolkit where to find the template files.
use Template;
my $tt2 = Template->new({
INCLUDE_PATH => '/usr/local/tt2/templates',
});
For a portable way to determine the installation 'templates' directory,
you can use the Template::Config->instdir() class method.
use Template;
my $tt2 = Template->new({
INCLUDE_PATH => Template::Config->instdir('templates'),
});
Note that you should set the INCLUDE_PATH to the 'templates' directory as shown here and don't be tempted to set the INCLUDE_PATH to 'templates/splash'. Many of the Splash! components use elements in the 'html' directory and contain directives of the form:
[% 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.
Simple template to format text according to a selected/unselected style, adding links, etc.
[% INCLUDE splash/text
content = 'Template Toolkit'
link = 'http://www.template-toolkit.org'
select = 0
bold = 1
%]
Configuration items:
The following items default to the relevant style values:
A thin wrapper around html/table, allowing a colour to be specified by name.
[% WRAPPER splash/table
col = 'aqua'
pad = 4
width = '100%'
%]
<tr>
<td>Foo</td>
<td>Bar</td>
</tr>
[% END %]
Configuration items:
Creates a row for an HTML table.
[% WRAPPER splash/table %]
[% WRAPPER splash/row col='marine' %]
<td>Foo</td><td>Bar</td>
[% END %]
[% WRAPPER splash/row col='aqua' %]
<td>Foo</td><td>Bar</td>
[% END %]
[% END %]
Configuration items:
Creates a cell for an HTML table.
[% WRAPPER splash/table + splash/row + splash/cell col='grey75' %]
Hello World
[% END %]
Configuration items:
A box created from a union of splash/table, splash/row and splash/cell. The following is equivalent to the previous example.
[% WRAPPER splash/box col='grey75' %]
Hello World
[% END %]
Configuration items are as per the individual templates.
Creates a small button with rounded corners.
[% INCLUDE splash/button
content = 'Template Toolkit'
select = 1
width = '50%'
%]
Configuration items:
The following items default to the relevant style values:
Creates a bar with rounded corners at either the top or bottom, and square corners on the other. Default has rounded at the top, set 'invert' to select bottom.
[% INCLUDE splash/bar
content = 'Hello World',
select = 1
%]
Configuration items:
The following items default to the relevant style values:
Generates a frame enclosing the content within crosshair corners.
[% INCLUDE splash/hair
content = 'Template Toolkit'
%]
Configuration items:
The following items default to the relevant style values:
Creates a menu as a series of splash/button elements.
[% buttons = [
{ text => 'One', link => 'one.html' }
{ text => 'Two', link => 'two.html' }
]
%]
[% INCLUDE splash/menu
select = 2 # Two
%]
Configuration items:
As above, but incorporated into a wider bar.
[% WRAPPER splash/menubar %]
Section Title
[% END %]

A table with a coloured edge.
[% WRAPPER splash/panel edge='black' fill='grey75' border=2 %]
<tr>
<td>Hello World</td>
</tr>
[% END %]
Configuration items:
The following items default to the relevant style values:
A union of splash/row + splash/cell.
