The problem is that you added extra spaces in front of your img tag.
The chomp support in TT only makes changes up to the first newline it
encounters (whether it is moving forwards (post chomp) or backwards
(pre chomp) in a string)
If you are post chomping, then TT will remove all spaces up to and
including the first newline (unless a non-whitespace character is
found before the newline). If you are prechomping it works exactly
the same way except working backwards into the string. All whitespace
up to and including the first newline is chomped (unless a
non-whitespace character is found before the newline).
Since you are post chomping, and there are spaces 'after' the newline,
they are never altered.
use Template;
my $template = Template->new;
$template->process(\*DATA) or die $template->error;
__DATA__
SPACES REMAIN: <td>
[%- IF 1 -%]
<img src="foo.jpg">
[%- END -%]
</td>
NO EXTRA SPACES: <td>
[%- IF 1 %]
<img src="foo.jpg">
[%- END %]
</td>
And here is the output:
SPACES REMAIN: <td> <img src="foo.jpg"></td>
NO EXTRA SPACES: <td><img src="foo.jpg"></td>
Cheers,
Cees
