| Subject: | warnings produced when tables=>1 and paras=>1 |
Hi,
I use HTML::FromText v2.05 under perl v5.8.4 (built for i386-linux-thread-multi) on a Debian Sarge box as part of Apache::MiniWiki under mod_perl and always run with warnings on. I get masses of warnings in the server logs originating from the table formatting code in HTML::FromText. I produced a minimal test case (attached) which is typical of the data we get. It produces a number of warnings when tables=>1 and paras=>1 (see attached) which is how it is used within Apache::MiniWiki. I'm sorry I can't fix it myself - I wouldn't know where to start!
Regards,

Note the pair of newlines after the title
and the space after 'This'
=cut
my $t2 = <<'EOF';
Title
This
is a minimal test case for the warning.
EOF
my $text = text2html( $t2,
urls => 0, email => 0, bold => 0,
underline =>0, paras => 1, bullets => 0, numbers=> 1,
headings => 0, blockcode => 0, tables => 1,
title => 1, code => 0
);
print $text;

And the result...
