I've got my solution, it's something like yours, and
it works fine. The main difference was I explicitely
used \x0d and \x0a because I wasn't sure if \n and \r
were defined to the same ASCII codes on all platforms.
Any double newlines I assume the user meant a
paragraph, any single ones just a line break.
Here's the code I finally used (embedded tags, sorry
if code wraps in ugly places due to this silly Yahoo
editor):
sub NL2HTML {
$_ = shift;
s/\x0d\x0a/\x0d/g; # Strip LF out of
CR/LF combinations (Convert DOS -> *nix)
s/\x0d{2}|\x0a{2}/<\/p><p>/g; # Replace double CR
or LF with paragraph break
s/\x0d|\x0a/<br>/g; # Replace single CR
or LF with line break
return "<p>$_</p>"; # Wrap whole thing in
outside <p></p>
}
