linewrap modification

I have a question about the linewarp function (see below). Standard the &linewrap($text) will make the whole tekst 'wrap', only I would like to maintain paragraphs.

So I can habe:

Code:
sub linewrap { 
# -------------------------------------------------------- 
# Wraps a line into 60 char chunks. 

    my $line = shift; defined $line or return ''; 
    my @data = split /\t/, $line; 
    my $columns = 60; 
    my $tabstop = 1; 
    my $frag = ''; 
    my $col  = $columns - 1; 

    for (@data) { 
        $_ = "$frag$_"; 
        $frag = ''; 
        s/(.{1,$columns}$)|(.{1,$col}(?:\S\s+|-(?=\w)))|(.{$col})/ 
            $3 ? "$3-\n" : 
            $2 ? "$2\n" : 
            (($frag = $1), '') 
        /ge; 
        $frag .= (' ' x ($tabstop - length($frag) % $tabstop)); 
    } 

    local $_ = join '', @data, $frag; 
    s/\s+$//gm; 
    return $_; 
}

Alex helped me out a while ago with what I think is the same problem. There is a post from a few weeks ago somewhere, but I couldn't find it in the search engine.

Anyway, here goes:

I wanted to use line breaks ('paragraphs') in my detailed view, and Alex told me to do this: in site_html_detailed (in either site_html.pl or site_html_templates.pl depending on whether you are using templates or not), add:

$rec{'FieldName'} =~ s/\n/ /g;

to change all line feeds to html line break tags.

Don't know if this will solve your problem. I works for me though :-)

Being old and stpid, I don't understand the workings of this Smile

Would it be possible to convert this:

to this:

Or to be more precise, a double line feed to ? I can add the opening and trailing to the template...

Any ideas ?
