how to chomp or trim extra characters like \n ,white spaces in text area using template toolkit

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

Hi,
how to chomp extra \n character or white space i am getting in text area using template toolkit.
I have an arrays of hashes,

my  @add=(
{
  name=>"Submode",
  value=>[ 'Ford Prefect', 'Slartibartfast' ],
}
);
i pass this array of  to template by
my %data = (
            add => \@add );
my $template = Template->new({
});
$template->process(temp.tmpl, \%data)
    || die $template->error();

In the template file i process as

[% FOREACH element = add %]
<textarea rows="4" name="[%element.name %]" >
 [% FOREACH option = element.value %]
 [% option %]
 [%END%]
</textarea>
[%END%]
[download]

when it is displayed in the template in text area
$
Ford Prefect$
$
Ford Prefect$
$
$
These extra characters are coming ie displaying with '\n'. Displaying it as

Ford Prefect

Ford Prefect
i tried with

"% option.chomp % and also % option.trim %"

but as the result nothing is displaying in the text area.
how to modify my code to trim or chomp extra characters or '\n' characters using template toolkit.

You can either use pre/post-chomping in your directives, as in: `[% FOREACH option = element.value %] [%- option -%] [% END %] # this is equivalent to writing those three directives on a single lin +e: # [% FOREACH option = element.value %][% option %][% END %]` [download] or you can use global options when you create your new Template object if you want such a behaviour applied everywhere: `my $template = Template->new( { PRE_CHOMP => 1, POST_CHOMP => 1, } );` [download] You can read more about those options in the Template::Manual::Config doc.

++ for mentioning Slartibartfast in a PM post ;-) Also, I must admit that I had to become 30 years old before I realized it's Ford Prefect and not Ford Perfect :-/ Thanks for that. holli, /regexed monk/	[reply] [d/l]
