I didn't know this was quite this easy.
In Controller/View/TT.pm you can add arbitrary filters:
__PACKAGE__->config(
FILTERS => {
commify => \&commify,
Define your sub:
# Perl Cookbook recipe 2.17
sub commify {
return 'N/A' unless defined $_[0] and length $_[0];
my $text = reverse $_[0];
$text =~ s/(\d\d\d)(?=\d)(?!\d*\.)/$1,/g;
return scalar reverse $text;
}
And then your templates can use the new filter:
[% num_views | commify %]
"1234" becomes "1,234". Etc. Neat, huh?
