[htmltmpl] The snarkiest way to print out specific values of a hash using HTML::Template?

[Justin S. <ju...@sk...>]

Hello all,

Been looking for a while for this answer, and seem to think it must 
have been asked before, although both the archives mentioned in the 
docs are down. So here goes:

Is there an easy way to pass a Hash to HTML::Template in hopes to use 
the key/value pairs, without putting it in a <TMPL_LOOP>?

Along with HTML::Template, I'm also familiar with Template-Toolkit. It 
had the dot syntax, where you can navigate a complex data structure 
like -

	$this->{that}->{then}->{some}

like this:

	[% this.that.then.some %]

I can't find anything similar in HTML::Template, except to put a 
<TMPL_LOOP> around the block of HTML when I want to access a value in a 
hash. I guess this is fine with me - as long as performance isn't 
completely dismal;

To clarify, in my Perl code, I have a hash that holds any errors that 
may have been put forth from an HTML form. Something like:

my %errors = (forgot_name => 1, impossible_zipcode => 1, 
is_the_unabomber => 0);

my theoretically HTML would be something like:

<TMPL_IF EXPR="errors.forgot_name == 1">

	<p>You forgot your name!</p>

</TMPL_IF>


Thanks for your time!
