We already called all the subs on @MyFooters and printed the result,
but this commit moves all the code from PrintFooters into subs and
puts those subs on @MyFooters. This allows us to write modules that
can better control where exactly their output should appear. In this
case the change was required in order to allow the Google +1 module to
coexist with code that maybe prints the comment form for all pages.
For example, knowing that the Google +1 sub is the first on one the
list because of unshift(@MyFooters, \&GooglePlusPrintFooter), we can
now write the following:
splice(@MyFooters, 1, 0, \&MyCommentsInTheFooter);
sub MyCommentsInTheFooter {
my ($id, $rev, $comment) = @_;
if (not $GooglePlusThisPagePrintedJournal
and (GetParam('action', 'browse') eq 'browse'
and $id and $CommentsPrefix
and $id ne $RCName
and $id !~ /^$CommentsPrefix(.*)/o)) {
my $target = $CommentsPrefix . $id;
my $page = '';
$page = PageHtml($target) if $IndexHash{$target};
return $q->div({-class=>'comment'},
$q->h2(T('Comments')),
$page)
. GetCommentForm("$CommentsPrefix$id", $rev, $comment);
}
}
The Google +1 extension was also fixed to not triger the EFF's Privacy
Badger. This is OK because we're using a two step button: The user
needs to click a button before we're loading the script from Google.
The EN DASH is not really required in year ranges such as 2012–2015 when
we're talking about comments in source code that is probably being
displayed in a fixed font anyway. Changing back to an ordinary hypen
allows us to make a meaningful test for use utf8.
