SYNOPSIS
use CGI::Pretty qw( :html3 );
# Print a table with a single data element
print table( TR( td( "foo" ) ) );
DESCRIPTIONCGI::Pretty is a module that derives from CGI. It's sole
function is to allow users of CGI to output nicely formatted
HTML code.
When using the CGI module, the following code:
print table( TR( td( "foo" ) ) );
produces the following output:
<TABLE><TR><TD>foo</TD></TR></TABLE>
If a user were to create a table consisting of many rows and
many columns, the resultant HTML code would be quite diffi-
cult to read since it has no carriage returns or indenta-
tion.
CGI::Pretty fixes this problem. What it does is add a car-
riage return and indentation to the HTML code so that one
can easily read it.
print table( TR( td( "foo" ) ) );
now produces the following output:
<TABLE>
<TR>
<TD>
foo
</TD>
</TR>
</TABLE>
Tags that won't be formatted
The <A> and <PRE> tags are not formatted. If these tags
were formatted, the user would see the extra indentation on
the web browser causing the page to look different than what
would be expected. If you wish to add more tags to the list
of tags that are not to be touched, push them onto the
@AS_IS array:
push @CGI::Pretty::AS_IS,qw(CODE XMP);

Customizing the Indenting
If you wish to have your own personal style of indenting,
you can change the $INDENT variable:
$CGI::Pretty::INDENT = "\t\t";
would cause the indents to be two tabs.
Similarly, if you wish to have more space between lines, you
may change the $LINEBREAK variable:
$CGI::Pretty::LINEBREAK = "\n\n";
would create two carriage returns between lines.
If you decide you want to use the regular CGI indenting, you
can easily do the following:
$CGI::Pretty::INDENT = $CGI::Pretty::LINEBREAK = "";
