There isn't anything built-in that does wrappers-in-reverse, but it's fairly
easy to roll your own using the TT equivalent of callbacks. You have your
outer wrapper callback (via INCLUDE or PROCESS) to a named BLOCK where you
define your content.
wrapper.tt2
[% test.push('wrapper.A');
test.push('wrapper.B');
PROCESS content; # Note the extra PROCESS
test.push('wrapper.C');
test.push('wrapper.D');
%]
inside.tt2
[% test = ['AA'];
PROCESS wrapper.tt2;
BLOCK content;
test.push('inside.A');
test.push('inside.B');
END;
test.join(', ');
%]
This generates the desired output:
AA, wrapper.A, wrapper.B, inside.A, inside.B, wrapper.C, wrapper.D
Although there's a little more code to write, this approach has the benefit
of supporting multiple "slots" that you want filled in. So it's ideal for
defining general layout templates, e.g. for a web site.
layout.tt2:
<div id="layout">
<div id="header">
[%- PROCESS header -%]
</div>
<div id="sidebar">
[%- PROCESS sidebar -%]
</div>
<div id="content">
[%- PROCESS content -%]
</div>
<div id="footer">
[%- PROCESS footer -%]
</div>
</div>
example.html:
[% PROCESS layout.tt2 %]
[% BLOCK header %]
Header content
[% END %]
[% BLOCK sidebar %]
Sidebar content
[% END %]
[% BLOCK content %]
Main content
[% END %]
[% BLOCK footer %]
Footer content
[% END %]
Output:
<div id="layout">
<div id="header">
Header content
</div>
<div id="sidebar">
Sidebar content
</div>
<div id="content">
Main content
</div>
<div id="footer">
Footer content
</div>
</div>
