The unwanted space is probably being introduced by the formatting
between your TT directives. For example, the spaces indicated in the
following extract will be converted to a single space when the output is
displayed in a browser:
[% ELSE %]
, [% author.get_name(LANGUAGE) %]
^^^^
[% END %]
There are a few ways to solve this. The messy way is to put all your
directives on one line so that no extra white space is introduced. A
better option is to use the PRE_CHOMP and POST_CHOMP options:
http://template-toolkit.org/docs/manual/Config.html#section_PRE_CHOMP_POST_CHOMP
You could experiment with individual chomping options by using the + or
- options in the tags. For example:
[% ELSE -%]
, [% author.get_name(LANGUAGE) %]
[%- END %]
Personally, I prefer to set the PRE_CHOMP configuration option to 1 and
the POST_CHOMP option to 0, and then explicitly disable chomping where
required by using the + option in the tag. For example:
<div class="comment [%+ loop.parity %]">
^
With PRE_CHOMP set to 1, the space between 'comment' and the start of
the TT tag would normally be removed. Adding the + option to the tag
prevents this from happening.
