Allows users of CGI to output nicely formatted HTML code by adding carriage returns and indentations to HTML markup for easy readability. For example, the following code:
#!/usr/local/bin/perl -w use CGI qw(:all); my $query = CGI->new( ); print $query->start_html( ); print $query->table( TR( td( "foo" ) ) ); print $query->end_html( );
outputs the following HTML:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html
PUBLIC "-//W3C//DTD XHTML Basic 1.0//EN"
"http://www.w3.org/TR/xhtml-basic/xhtml-basic10.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en-US"><head><title>Untitled Document</title>
</head><body><table><tr><td>foo</td></tr></table></body></html>which is ugly. You can make it prettier with CGI::Pretty:
#!/usr/local/bin/perl -w use CGI::Pretty qw( :html3 ); my $query = CGI->new( ); print $query->start_html( ); # Print a table with a single data element print $query->table( TR( td( "foo" ) ) ); print $query->end_html( );
