Brethren,

I want to access a csv datafile from a template for the Template Toolkit. I have managed to read from a "real" database, using Template::Plugin::DBI as follows: 
[% USE DBI('dbi:ADO:Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:/pr
+ojekte/vdx/daten/users.mdb', '', '') -%]
[% FOREACH user = DBI.query( 'SELECT * FROM users' ) -%]
    [% user.id %] [% user.name %]
[% END -%]

That is simple and straightforward. Now I have this script, that uses DBD::CSV to access a textfile. 
use strict;
use warnings;

use DBI;
use DBD::CSV;

my $dbh = DBI->connect(qq{DBI:CSV:csv_sep_char=\\;});
$dbh->{'csv_tables'}->{'users'} =
{
    'file' => 'c:/projekte/vdx/daten/users.txt',
    'col_names' => ["id", "name"]
};

my $sth = $dbh->prepare("SELECT * FROM users");
$sth->execute;

while( my $row = $sth->fetchrow_hashref )
{
    print $row->{id}, ";", $row->{name}, "\n";
}

I want to do the same with a template like the one above. But I cannot figure out how to pass the additional parameters into Template::Plugin::DBI, namely the filename and the fieldnames. All my searching was fruitless.

Btw, I know there is Template::Plugin::Datafile, but this plugin won't let me specify the fieldnames.

I'm pretty sure I could write my own plugin to interface with DBD::CSV, but I don't want to if I don't have to. Any suggestions?

Thanks in advance.
