我可以在模板内设置模板继承吗?(模板工具包)

像这样的事情应该可以做到:

主.tt:

This is a main template [% GET state %]
[% SET iname = state _ ".tt" %]
[% TRY %]
[% INCLUDE "$iname" %]
[% CATCH %]
[% INCLUDE default.tt %]
[% END %]
End of main template

默认.tt:

This is default template

s1.tt:

This is template for state s1.

t、 损益:

#! /usr/bin/perl
use 5.006;
use strict;
use warnings;

use Template;
my $tt = Template->new();
$tt->process("main.tt", { state => "s1" })
  || die $tt->error, "\n";
print "---------\n";
$tt->process("main.tt", { state => "unknown" })
  || die $tt->error, "\n";

运行时 t.pl :

This is a main template s1
This is template for state s1.
End of main template
---------
This is a main template unknown
This is default template
End of main template
