[cgiapp] [patch] CAP::MessageStack + CAP::FormState

[Alex]

Hi!

I had a quick look at the source of CAP::TT. In contrast to my previous
assumption, you use Template 2.0. So you should set tmpl_class to Template -
if you want to.

I don't get exactly what your import method does, as I'm not very familiar
with all that import and plugin stuff.

Here it is (original), v. 1.04
[code]
sub import {
    my $pkg = shift;
    my $callpkg = caller;
    no strict 'refs';
    foreach my $sym (@EXPORT) {
        *{"${callpkg}::$sym"} = \&{$sym};
    }
    $callpkg->tt_config(@_) if @_;
    if ($callpkg->isa('CGI::Application')) {
        $callpkg->new_hook('tt_pre_process');
        $callpkg->new_hook('tt_post_process');
    } else {
        warn "Calling package is not a CGI::Application module so not
installing tt_pre_process and tt_post_process hooks.  If you are using \@ISA
instead of 'use base', make sure it is in a BEGIN { } block, and make sure
these statements appear before the plugin is loaded";
    }

}
[/code]

E.g. I don't know why you are using that "no strict refs" and the loop
afterwards. But then you do the configuration and declare the hooks for
classes, that are based on CGI::Application.
This is the part, where I think, you could set up the tmpl_class.
[code]
sub import {
    my $pkg = shift;
    my $callpkg = caller;
    no strict 'refs';
    foreach my $sym (@EXPORT) {
        *{"${callpkg}::$sym"} = \&{$sym};
    }
    $callpkg->tt_config(@_) if @_;
    $callpkg->html_tmpl_class('Template'); # << here
    if ($callpkg->isa('CGI::Application')) {
        $callpkg->new_hook('tt_pre_process');
        $callpkg->new_hook('tt_post_process');
    } else {
        warn "Calling package is not a CGI::Application module so not
installing tt_pre_process and tt_post_process hooks.  If you are using \@ISA
instead of 'use base', make sure it is in a BEGIN { } block, and make sure
these statements appear before the plugin is loaded";
    }

}
[/code]

HTH, Alex

I am happy to set that parameter in CAP::TT if you like.  It makes sense for
there to be a way for plugins to know what templating system is being used.

It does bring up another question though.  What do I set it to?  It is not a
method that CAP::TT would call itself, so I guess just setting to to
'Template::Toolkit' would make the most sense.
