Hi Bod,
Making use of Template's EVAL_PERL constructor option :
use strict;
use warnings;
use Template;
my $tt = Template->new({ EVAL_PERL => 1 });
my $str = 'This is too verbose to be printed in its entirety';
# 16 characters here ^
$tt->process(\*DATA, { string => $str }) || die $tt->error;
__DATA__
Original string : [% string %]
Formatted string : [%- PERL -%]
if ( length '[%- string -%]' > 16 ) {
(my $truncated = '[%- string -%]') =~ s/^(.{0,16}\b).*$/$1.../
+s;
print $truncated;
}
else {
print '[% string %]';
}
[%- END -%]
Output:
Original string : This is too verbose to be printed in its entirety
Formatted string : This is too ...
Hope this helps!
The way forward always starts with a minimal test.
