=head1 NAME
|
||||
SL::Layout::Base - Base class for layouts
|
||||
=head1 SYNOPSIS
|
||||
package SL::Layout::MyLayout;
|
||||
use parent qw(SL::Layout::Base);
|
||||
=head1 DESCRIPTION
|
||||
| 048f2af4 | Geoffrey Richardson | For a description of the external interface of layouts in general see
|
||
| 42f69828 | Sven Schöling | L<SL::Layout::Dispatcher>.
|
||
This is a base class for layouts in general. It provides the basic interface
|
||||
and some capabilities to extend and cascade layouts.
|
||||
=head1 IMPLEMENTING LAYOUT CALLBACKS
|
||||
There are eight callbacks (C<pre_content>, C<post_content>, C<start_content>,
|
||||
| 048f2af4 | Geoffrey Richardson | C<end_content>, C<stylesheets>, C<stylesheets_inline>, C<javascripts>,
|
||
| 42f69828 | Sven Schöling | C<javascripts_inline>) which are documented in L<SL::Layout::Dispatcher>. If
|
||
you are writing a new simple layout, you can just override some of them like
|
||||
this:
|
||||
package SL::Layout::MyEvilLayout;
|
||||
sub pre_content {
|
||||
'<h1>This is MY page now</h1>'
|
||||
}
|
||||
sub post_content {
|
||||
'<p align="right"><small><em>Brought to you by my own layout class</em></small></p>'
|
||||
}
|
||||
To preserve the sanitizing effects of C<stylesheets> and C<javascripts> you should instead do the following:
|
||||
sub stylesheets {
|
||||
$_[0]->add_stylesheets(qw(mystyle1.css mystyle2.css);
|
||||
$_[0]->SUPER::stylesheets;
|
||||
}
|
||||
If you want to add something to a different layout, you should write a sub
|
||||
layout and add it to the other layouts.
|
||||
=head1 SUB LAYOUTS
|
||||
Layouts can be aggregated, so that common elements can be used in different
|
||||
layouts. Currently this is used for the L<None|SL::Layout::None> sub layout,
|
||||
which contains a lot of the stylesheets and javascripts necessary. Another
|
||||
example is the L<Top|SL::Layout::Top> layout, which is used to generate a
|
||||
common top bar for all menu types.
|
||||
To add a sub layout to your layout just overwrite the sub_layout method:
|
||||
package SL::Layout::MyFinalLayout;
|
||||
sub init_sub_layout {
|
||||
[
|
||||
SL::Layout::None->new,
|
||||
SL::Layout::MyEvilLayout->new,
|
||||
]
|
||||
}
|
||||
You can also add a sublayout at runtime:
|
||||
$layout->add_sub_layout(SL::Layout::SideBar->new);
|
||||
The standard implementation for the callbacks will see to it that the contents
|
||||
of all sub layouts will get rendered.
|
||||
=head1 COMBINING SUB LAYOUTS AND OWN BEHAVIOUR
|
||||
This is still somewhat rough, and improvements are welcome.
|
||||
For the C<*_content> callbacks this works if you just remember to dispatch to the base method:
|
||||
sub post_content {
|
||||
return $_[0]->render_status_bar .
|
||||
$_[0]->SUPER::post_content
|
||||
}
|
||||
| 9836938f | Sven Schöling | Stylesheets and Javascripts can be added to every layout and sub-layout at
|
||
runtime with L<SL::Layout::Dispatcher/add_stylesheets> and
|
||||
L<SL::Layout::Dispatcher/add_javascripts> (C<use_stylesheets> and
|
||||
C<use_javascripts> are aliases for backwards compatibility):
|
||||
$layout->add_stylesheets("custom.css");
|
||||
$layout->add_javascripts("app.js", "widget.js");
|
||||
Or they can be overwritten in sub layouts with the calls
|
||||
L<SL::Layout::Displatcher/static_stylesheets> and
|
||||
L<SL::Layout::Dispatcher/static_javascripts>:
|
||||
sub static_stylesheets {
|
||||
"custom.css"
|
||||
}
|
||||
sub static_javascripts {
|
||||
qw(app.css widget.js)
|
||||
| 42f69828 | Sven Schöling | }
|
||
| 9836938f | Sven Schöling | Note how these are relative to the base dirs of the currently selected
|
||
stylesheets. Javascripts are resolved relative to the C<js/> basedir.
|
||||
Setting directly with C<stylesheets> and C<javascripts> is eprecated.
|
||||
| 42f69828 | Sven Schöling | =head1 GORY DETAILS ABOUT JAVASCRIPT AND STYLESHEET OVERLOADING
|
||
| 048f2af4 | Geoffrey Richardson | The original code used to store one stylesheet in C<< $form->{stylesheet} >> and
|
||
| 42f69828 | Sven Schöling | allowed/expected authors of potential C<bin/mozilla/> controllers to change
|
||
that into their own modified stylesheet.
|
||||
This was at some point cleaned up into a method C<use stylesheet> which took a
|
||||
string of space separated stylesheets and processed them into the response.
|
||||
| 048f2af4 | Geoffrey Richardson | A lot of controllers are still using this method so the layout interface
|
||
supports it to change as little controller code as possible, while providing the
|
||||
| 42f69828 | Sven Schöling | more intuitive C<add_stylesheets> method.
|
||
At the same time the following things need to be possible:
|
||||
=over 4
|
||||
=item 1.
|
||||
Runtime additions.
|
||||
$layout->add_stylesheets(...)
|
||||
Since add_stylesheets adds to C<< $self->{stylesheets} >> there must be a way to read
|
||||
from it. Currently this is the deprecated C<use_stylesheet>.
|
||||
=item 2.
|
||||
Overriding Callbacks
|
||||
A leaf layout should be able to override a callback to return a list.
|
||||
=item 3.
|
||||
Sanitizing
|
||||
| 048f2af4 | Geoffrey Richardson | C<stylesheets> needs to retain its sanitizing behaviour.
|
||
| 42f69828 | Sven Schöling | |||
=item 4.
|
||||
Aggregation
|
||||
The standard implementation should be able to collect from sub layouts.
|
||||
=item 5.
|
||||
| 048f2af4 | Geoffrey Richardson | Preserving Inclusion Order
|
||
| 42f69828 | Sven Schöling | |||
Since there is currently no standard way of mixing own content and including
|
||||
sub layouts, this has to be done manually. Certain things like jquery get added
|
||||
in L<SL::Layout::None> so that they get rendered first.
|
||||
=back
|
||||
The current implementation provides no good candidate for overriding in sub
|
||||
classes, which should be changed. The other points work pretty well.
|
||||
=head1 BUGS
|
||||
| 3dc29e42 | Sven Schöling | * stylesheet/javascript interface is a horrible mess.
|
||
* It's currently not possible to do compositor layouts without assupmtions
|
||||
about the position of the content. That's because the content will return
|
||||
control to the actual controller, so the layouts need to know where to split
|
||||
pre- and post-content.
