[htmltmpl] Output formatting in the presence of TMPL_IF

[Offer K. <off...@gm...>]

Hi H::T users,
If I have a section in my template file that looks like:

<TMPL_IF NAME="foo">
content when foo is true
</TMPL_IF>
more content

This section will be reduced (in the case of 'foo' being false) to an
empty line followed by "more content" on the next line. As I'm using
HTML::Template for non-HTML purposes I do care about final output
formatting and the empty line is ugly. On the other hand trying to
make sure I don't get an empty line leads to the following uglier
solution:

<TMPL_IF NAME="foo">content when foo is true\n</TMPL_IF>more content

Is there any other solution?

Best regards,
Offer Kaye

You've covered the two most usual approaches. Anything else will involve
processing the string you get from the output() function.

$htmltemplatefilters = [
                          # remove any space at the start of a line if it is
immediately before a tmpl tag
                          { sub => sub { my $text_aref = shift; s#^[\t
]+(</?tmpl_[^>]+>)#$1#gi for @{$text_aref} },
                            format => 'array' },
                          # remove any \n and \r following a tmpl tag
                          { sub => sub { my $text_ref = shift; $$text_ref =~
s#(</?tmpl_[^>]+>)[\r\n]+#$1#sgi },
                            format => 'scalar' },
                       ];

      my $template = HTML::Template->new(
                                           filename          =>
get_template('example.tmpl'),
                                           filter            =>
$htmltemplatefilters,
                                        );

thats how we handle it. So our code is readable, but the output result is
formatted correctly.

HTH,
Alex
