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.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
