in reply to Free Nodelet gets templating features

First, here is the updated (again) code for the Free Nodelet:

[% my $html = $VARS->{freenodelet} || 'Visit [Free Nodelet Settings]' .' to enter HTML to go here.'; $html= htmlcode( 'expandfreenodelet','', $html ); return $html; %]

Next, is the expandfreenodelet code that gets used above and below:

my( $html, $just )= @_; my $AUTHOR= getNodeById( $NODE->{author_user} ); my %var= ( id => $NODE->{node_id}, title => $NODE->{title}, author_id => $AUTHOR->{node_id}, author_name => $AUTHOR->{title}, author_title => $AUTHOR->{title}, user_id => $USER->{node_id}, user_name => $USER->{title}, user_title => $USER->{title}, ); # root_id root_title sect_id sect_title $html =~ s{`([\[\]]|`+|(\w+)([%&]?)`?|.)}{ my $s= $1; if( '[' eq $s ) { $just ? '[' : '`{'; } elsif( ']' eq $s ) { $just ? ']' : '`}'; } elsif( defined $2 ) { my( $key, $suff )= ( $2, $3 ); my $val; if( $key =~ /^_./ ) { $val= $q->param($key); $val= $q->param( substr($key,1) ) if ! defined $val; } else { $val= $var{ lc $key }; } if( ! defined $val ) { $val= "`$key$suff`" } elsif( $suff eq '%' ) { $val= $q->escape($val); } elsif( $suff eq '&' ) { $val= $q->escapeHTML($val); } $val; } elsif( $s =~ /^`/ ) { $just ? $s : '`'.$s; } else { $just ? '`'.$s : '``'.$s; } }seg; return $html if $just; $html =~ s{(<!--.*?-->)|\[([^\[\]]{1,4096})\]}{ $1 ? $1 : handleLinks($2) }seg; $html =~ s{`([{}]|`+|.)}{ my $s= $1; if( '{' eq $s ) { '['; } elsif( '}' eq $s ) { ']'; } elsif( $s =~ /^`/ ) { $s; } else { '`'.$s; } }seg; return $html;

Finally, here is the _freer opcode:

my $want= ($q->param("at"))[-1]; my $html= $VARS->{freenodelet}; my $update= 0; $html =~ s{(<!--(\w+-(?!->))?(.*?)(-\w+)?-->)}{ my( $cmnt, $pre, $mid, $post )= ( $1, $2, $3, $4 ); my $found= $pre || $post || ''; $found =~ s/-//; if( $found ne $want ) { $cmnt; } else { my $add= htmlcode( 'expandfreenodelet','', $mid, 1 ); $update++; $pre ? $add . $cmnt : $cmnt . $add; } }ges; # Everything::printLog( "Expanding -$want- in $USER->{title}'s freenod +elet: $update updates$/" ); $VARS->{freenodelet}= $html if $update;
