NAME

Band.pm - Yet another perl-based HTML Template technology

DESCRIPTION

Perl CGI module useful for merging HTML from designers with dynamic perl data structures, using a single <--band--> tag that defines conditional and repeating "bands" of HTML with nested namespaces for scalar variable interpolation.

Band Objects allow you to define define tree structures (nested bands) within html template files that contain conditional or repeatable html "bands" which include simple scalar variables expanded at run time.

SYNOPSIS

	# instantiate a new Band object
	$myskin=new Band;
	
	# initialize it with a template file (html with <!--band--> tags)
	$myskin->template(file=>$file) 
		or die "error setting template from file: '$file' - ". $myskin->error;
	
	# parse the template (validate the template syntax)
	$myskin->parse or die "error parsing template - ". $myskin->error;
	
	# assign a hash of "global" tokens to template
	$myskin->bandtoken( %token) 
		or die "can't set global band token - ".$myskin->error;
	
	# define a list of hashes to populate a repeating band
	$rows=({%row1hash}, {%row2hash}, ...);
	
	# assign the named rowset to the the template
	$myskin->rowset(myrows, @rows) or die "can't set 'myrows' list - ".$myskin->error;
	
	# print the merged results
	print "Content-Type: text/html\n\n", 
		$myskin->merge ;
	
	# to debug your template's stucture, play with this:
	print "<pre>extracting</pre>";
	print "Content-Type: text/html\n\n", 
		$myskin->source(
			with_band_tags => 1, 
			hide_implied_tags => 1, 
			htmlify => 0,
			testresults => 1, 
		#	indent => 1,
		#	show_scope=>1,
		#	show_tokens=>1,

			merge =>1,

		);
