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

Hi all,

does anyone know what is the character for end of string in Template Toolkit? I am trying to do a search and replace, in this example to remove the last ','. This doesn't seem to work:
[% "Blah Blah," | replace(',$', '') %]

thanks

    The regular '$' works just fine for me (Perl 5.8.8 on Linux, TT-2.20 — just in case it matters): 

    #!/usr/bin/perl

use Template;

my $template = Template->new();

my $input = q{[% "Blah, Blah," | replace(',$', '') %]};

$template->process(\$input) || die $template->error();   # output "Bla
+h, Blah"

    should work as well.

      Thanks guys! You are right. However, my actual program has this in a string variable and it doesn't work if I have it like this:
      [% foo = 'Blah blah,' %]
[% foo  | replace(',$', '') %]

      Any idea why? Appreciate the help!

        Not true. It works fine. 
        use Template qw( );

my $template = Template->new();

my $input = <<'__EOI__';
[% foo = 'Blah blah,' %]
[% foo  | replace(',$', '') %]
__EOI__

$template->process(\$input)
   or die $template->error();

Blah blah
