It's sole function is to allow users of \s-1CGI\s0 to output nicely formatted \s-1HTML\s0 code. .PP When using the \s-1CGI\s0 module, the following code: print table( \s-1TR\s0( td( \*(L"foo\*(R" ) ) ); .PP produces the following output: <\s-1TABLE\s0><\s-1TR\s0><\s-1TD\s0>foo</TD></TR></TABLE> .PP If a user were to create a table consisting of many rows and many columns, the resultant \s-1HTML\s0 code would be quite difficult to read since it has no carriage returns or indentation. .PP CGI::Pretty fixes this problem. What it does is add a carriage return and indentation to the \s-1HTML\s0 code so that one can easily read it. .PP .Vb 1 \& print table( TR( td( "foo" ) ) ); .Ve .PP now produces the following output: <\s-1TABLE\s0> <\s-1TR\s0> <\s-1TD\s0>foo</TD> </TR> </TABLE> .SS "Recommendation for when to use CGI::Pretty" .IX Subsection "Recommendation for when to use CGI::Pretty" CGI::Pretty is far slower than using \s-1CGI\s0.pm directly. A benchmark showed that it could be about 10 times slower. Adding newlines and spaces may alter the rendered appearance of \s-1HTML\s0. Also, the extra newlines and spaces also make the file size larger, making the files take longer to download. .PP With all those considerations, it is recommended that CGI::Pretty be used primarily for debugging. .SS "Tags that won't be formatted" .IX Subsection "Tags that won't be formatted" The following tags are not formatted: <a>, <pre>, <code>, <script>, <textarea>, and <td>. 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 \f(CW@AS_IS\fR array: .PP .Vb 1 \& push @CGI::Pretty::AS_IS,qw(XMP); .Ve .SS "Customizing the Indenting" .IX Subsection "Customizing the Indenting" If you wish to have your own personal style of indenting, you can change the \&\f(CW$INDENT\fR variable: .PP .Vb 1 \& $CGI::Pretty::INDENT = "\et\et"; .Ve .PP would cause the indents to be two tabs. .PP Similarly, if you wish to have more space between lines, you may change the \&\f(CW$LINEBREAK\fR variable: .PP .Vb 1 \& $CGI::Pretty::LINEBREAK = "\en\en"; .Ve .PP would create two carriage returns between lines. .PP If you decide you want to use the regular \s-1CGI\s0 indenting, you can easily do the following: .PP .Vb 1 \& $CGI::Pretty::INDENT = $CGI::Pretty::LINEBREAK = ""; .Ve .SH "AUTHOR" .IX Header "AUTHOR" Brian Paulsen <Brian@ThePaulsens.com>, with minor modifications by Lincoln Stein <lstein@cshl.org> for incorporation into the \s-1CGI\s0.pm distribution. .PP Copyright 1999, Brian Paulsen.
