+=head1 NAME
+
+SL::Presenter::Text - Presenter module for assorted text helpers
+
+=head1 SYNOPSIS
+
+ my $long_text = "This is very, very long. Need shorter, surely.";
+ my $truncated = $::request->presenter->truncate($long_text, at => 10);
+ # Result: "This is..."
+
+=head1 FUNCTIONS
+
+=over 4
+
+=item C<truncate $text, [%params]>
+
+Returns the C<$text> truncated after a certain number of
+characters.
+
+The number of characters to truncate at is determined by the parameter
+C<at> which defaults to 50. If the text is longer than C<$params{at}>
+then it will be truncated and postfixed with '...'. Otherwise it will
+be returned unmodified.
+
+=item C<simple_format $text>
+
+Applies simple formatting rules to C<$text>: The text is put into
+paragraph HTML tags. Two consecutive newlines are interpreted as a
+paragraph change: they close the current paragraph tag and start a new
+one. Single newlines are converted to line breaks. Carriage returns
+are removed.

The tag's C<id> defaults to C<name_to_id($name)>.
+If the option C<with_optgroups> is set then this function expects
+C<\@collection> to be one level deeper. The upper-most level is
+translated into a HTML C<optgroup> tag. So the structure becomes:
+
+=over 4
+
+=item 1. Array of array references. Each element in the
+C<\@collection> is converted into an optgroup.
+
+=item 2. The optgroup's C<label> attribute will be set to the the
+first element in the array element. The second array element is then
+converted to a list of C<option> tags like it is described above.
+
+=back
+
+Example for use of optgroups:
+
+ # First in a controller:
+ my @collection = (
+ [ t8("First optgroup with two items"),
+ [ { id => 42, name => "item one" },
+ { id => 54, name => "second item" },
+ { id => 23, name => "and the third one" },
+ ] ],
+ [ t8("Another optgroup, with a lot of items from Rose"),
+ SL::DB::Manager::Customer->get_all_sorted ],
+ );
+
+ # Later in the template:
+ [% L.select_tag('the_selection', COLLECTION, with_optgroups=1, title_key='name') %]
+
=item C<yes_no_tag $name, $value, %attributes>
Creates a HTML 'select' tag with the two entries C<yes> and C<no> by
L.tab('Awesome tab wih much info', '_much_info.html', if => SELF.wants_all)
