Beginer TT question

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I'm attempting to learn the Template Toolkit and I'm having trouble even getting started. Can anyone see what I'm doing wrong?


#!/usr/bin/perl

use strict;
use Template;


my $template = new Template;

my $file = 'tt/template.html';

my $data = {
    env => \%ENV,
};

print "Content-type: text/html\n\n";

$template->process($file, $data) || die $template->error;
[download]

the template file:


<html>

<head>

</head>


<body>

<ul>    

[% foreach thing in env.keys.sort %]
    
    <li><b>{% thing %}:</b>[% env.thing %]</li>
    
[% end %]

</ul>
</body>
</html>
[download]

the output:

# perl template.pl
Content-type: text/html

file error - parse error - tt/template.html line 12: unexpected token 
+(thing)
  [% foreach thing in env.keys.sort %]
[download]

I even tried a


[% get env %]
[download]

at the top of my template and that didn't seem to do any good either.

Thanks.
AM

`[% FOREACH thing = env.keys.sort %] <li><b>[% thing %]:</b>[% env.$thing %]</li> [% END %]` [download] so you were close .. few points: case matters (unless you explcitly say otherwise w/the ANYCASE option -- see docs) check the docs http://www.template-toolkit.org/ for the loop syntax and other control statements (IF, etc) note the `$` that's needed in `[% env.$thing %]` -- without it, you're getting the key 'thing' and not the key that matches the value of thing.

So close ... it's `FOREACH thing = env.keys.sort` That's =, not in. Try this instead: `[% FOREACH thing = env.keys.sort %] [% thing %] [% END %]` [download] UPDATE: yes ... case matters. :) jeffa L-LL-L--L-LL-L--L-LL-L-- -R--R-RR-R--R-RR-R--R-RR B--B--B--B--B--B--B--B-- H---H---H---H---H---H--- (the triplet paradiddle with high-hat)	[reply] [d/l]

So close ... it's FOREACH thing = env.keys.sort That's =, not in. Case sensitivity aside, `IN' is a synonym for `=' in this context, as mentioned in Template::Manual::Directives `</pedant>` [download] MB	[reply] [d/l]

that doesn't work either. I tried it before I posted.	[reply]


No such thing as a small change
