loop.first, loop.last

Hi,

I'm looping through an array of hashes with
"foreach" and have problems 
using "loop.last":

<p>
<% foreach record in record_list %>
<% record_lastname>, <% record.firstname %><%
if not loop.last%>; <% end %>
<% end %>:
</p>

However, the Template module throws an error:
file error - parse error - pub_author.tmpl line 3:
unexpected token 
(LAST) [% if not loop.last %].

The same error is thrown by "unless loop.last".

Can someone please explain this to me?

Thank you, and best regards,

Birgit Kellner

Unless you've done something other than just change your
delimiters
away from [% %] to <% %>, the keywords are also
(mostly) case-sensitive.
So you want things like:

<% FOREACH record IN record_list %>

etc.

Randal,

thanks, but that's not the problem. I'm calling the module
with the 
"anycase" option enabled.

$tt = Template->new( { INCLUDE_PATH =>
$vars->."/" . 
"template" , TAG_STYLE => 'asp', ANYCASE
=> 1}) || die("$!");

Besides, if it were the problem, I suppose the error message
would be 
different, and it wouldn't just be thrown with
"loop.last". I should add 
that the same template works perfectly with
"loop.first", except that 
then of course it doesn't do what I want 

Birgit

Hi Birgit -

Sorry this does not solve the question of the
"loop.last" error message, 
but if loop.first works maybe you could do something like:

    <% foreach record in record_list %>
       <% if not loop.first%>; <% end %><%
record_lastname %>, <% record.firstname %>
    <% end %>:

Hi Birgit,

The problem is the with the anycase option set, TT gets
confused between 
the '.last' in 'loop.last' and the 'LAST' keyword.  I
wasn't aware of 
the problem until you mentioned it, but it does make sense.

Unfortunately the design of the parser in TT2 is such that
it can't be 
fixed easily, if at all.  That's one of the reasons we
totally 
re-designed the parser for TT3, although that doesn't help
you now.

The only thing I can suggest is to disable the anycase
option or not use 
loop.last :-(

Sorry about that.  If it's any consolation I'm kicking
myself for it 
right now.

A

What about making an alias?  loop.final?

That seems like a good idea.
