<nowiki>Through the magic of autoloading, this class can make any html tag by calling a class method with the same name as the tag you want.  For examples, use "hr()" to make a "<HR>" tag, or "p(’text’)" to make "<P>text</P>".  This also means that if you mis-spell any method name, it will still make a new tag with the mis-spelled name. For autoloaded methods only, the method names are case-insensitive.

If you call a class method whose name ends in "_group", this will be interpreted as an instruction to make a list of tags whose name are the part of the method name preceeding the "_group".  For example, calling "td_group( [’here’,’we’,’are’] )" results in "<TD>here</TD><TD>we</TD><TD>are</TD>" being generated.  The arguments that you call this method are exactly the same as for calling a method to make a single tag of the same name, except that the extra optional parameter "list" can be used to force an ARRAY ref of the new tags to be returned instead of a scalar.  The symantec difference is that any arguments whose values are ARRAY refs are interpreted as a list of values where each one is used in a separate tag; for a single tag, the literal ARRAY ref itself would be used.

The number of tags produced is equal to the length of the longest ARRAY ref passed as an argument.  For any other arguments who have fewer than this count, their last value is replicated and appended enough times as necessary to make them the same length.  The value of a scalar argument is used for all the tags.  For example, calling "input_group( type => checkbox, name => ’letters’, value => [’a’,’b’,’c’] )" produces ’<INPUT TYPE="checkbox" NAME="letters" VALUE="a"><INPUT TYPE="checkbox" NAME="letters" VALUE="b"><INPUT TYPE="checkbox" NAME="letters" VALUE="c">’.

All autoloaded methods require their parameters to be in named format.  These names and values correspond to attribute names and values for the new tags.  Since "no value" attributes are essentially booleans, they can have any true or false value associated with them in the parameter list, which won’t be printed.  If an autoloaded method is passed exactly one parameter, it will be interpreted as the "text" that goes between the tag pair (<TAG>text</TAG>) or after "start tags" (<TAG>text).  The same result can be had explicitely by passing the named parameter "text".  Most static (non-autoloaded) methods require positional parameters, except for start_html(), which can take either format.  The names of any named parameters can optionally start with a "-".
