This is not a bad idea, but:
> return sub {
> my $text = shift;

In the case of something like …, this will truncate eight
characters from $text, but replace it with something much smaller (it
looks like two characters width in my browser).
Maybe something that accepts an optional length, in the case of
providing your own truncate string:
sub truncate_filter_factory {
my ($context, $len, $char, $chop) = @_;
$len = 32 unless defined $len;
if ($chop) {
$len -= int($chop);
}
else {
$char = "..." unless defined $char;
}
return sub {
my $text = shift;
return $text if length $text < $len;
return substr($text, 0, $len) . $char;
}
}
The normal case is not changed, and in the case of providing your own
characters, you can specify how much to truncate (default none):
[% text | truncate(40, '…', 3) %]
*shrug* Maybe this is too much, though.
