       HTML::Perlinfo::HTML - HTML documentation for the perlinfo library

       HTML::Perlinfo validates	as XHTML 1.0 Transitional.

       In the perlinfo library,	HTML::Perlinfo and HTML::Perlinfo::Modules use
       the internal module HTML::Perlinfo::Common for HTML generation. This
       document	provides information on	that HTML and its manipulation.

       You can capture the HTML	output by assigning it to a scalar. Then you
       can alter the HTML before printing it or	doing something	else with it.
       Here is an example that uses the	perlinfo function from HTML::Perlinfo:

	   use HTML::Perlinfo;

	   my $example = perlinfo();	# Now I	can do whatever	I want with $example
	   $example =~ s/Perl/Java/ig;	# Make everyone	laugh
	   print $example;

       Another option is to use	object attributes which	make altering some
       HTML elements less helter skelter.

       These object attributes allow you to change the HTML CSS	settings to
       achieve a stylish effect. Please	see your favorite HTML guide for
       acceptable CSS values. Refer to the HTML	source code of the perlinfo
       page for	the defaults.

       Attribute name/Corresponding CSS	element

	title		   / page title	(only non-CSS element)
	bg_image	   / background_image
	bg_position	   / background_position
	bg_repeat	   / background_repeat
	bg_attribute	   / background_attribute
	bg_color	   / background_color
	ft_family	   / font_familty
	ft_color	   / font_color
	lk_color	   / link color
	lk_decoration	   / link text-decoration
	lk_bgcolor	   / link background-color
	lk_hvdecoration	   / link hover	text-decoration
	header_bgcolor	   / table header background-color
	header_ftcolor	   / table header font color
	leftcol_bgcolor	   / background-color of leftmost table	cell
	leftcol_ftcolor	   / font color	of left	table cell
	rightcol_bgcolor   / background-color of right table cell
	rightcol_ftcolor   / font color	of right table cell

	   $p =	HTML::Perlinfo->new(
		       bg_image	 => '',
		       bg_repeat => 'yes-repeat'

       This method prints the head container tags containing the style sheet,
       along with a few	other html tags. It is useful to call this method when
       full_page is set	to 0 and you are piecing together multiple perlinfo
       pages into one page. For	example:

	   $m =	HTML::Perlinfo::Modules->new( full_page	=> 0 );	   # Just the bare essentials please

	   $m->print_htmlhead;	# Print	the beginning of an html document

	   $m->print_modules(  from =>'/home/paco',
			       section	=> 'The	Modules	in Paco's Home Directory'

	   $m->print_modules(  from =>'/home/cowboy',
			       section	=> 'The	Modules	in Cowboy's Home Directory'

       When full_page is set to	1 (the default value), print_htmlhead is
       called internally. Note that you	can still set CSS values in the
       constructor even	when full_page is set to 0 and see the results in

	   $m =	HTML::Perlinfo::Modules->new(
	       full_page => 0,
	       bg_color	 => 'gray'

	   $m->print_htmlhead;	# Prints a HTML	document with a	gray background

       Of course, you don't have to use	the print_htmlhead method. You could
       insert your own HTML with your own style	sheet when you set full_page
       to 0.

       Do you want only	a fragment of HTML and not a page with body tags
       (among other things)? Then the full_page	option is what you need	to use
       (or a regular expression, as explained above). This option allows you
       to add your own header/footer if	you so desire. By default, the value
       is 1. Set it to 0 to output the HTML report with	as little HTML as

	   $p =	HTML::Perlinfo->new( full_page	=> 0  ); # Change value	to 1 to	get a full HTML	page

       By default, there will be useful	links in most of the presented HTML in
       the perlinfo library. These links are for pages on
       Even the	info_config method lists links to the config options in	the
       core Config module.

       To manipulate links in the perlinfo library, you	can use	the links
       attribute in the	info methods. Not to be	confused with the "link"
       attribute in the	HTML::Perlinfo::Module (which allows you to provide
       your own	links for modules), this attribute's primary purpose is	to
       turn on linking or turn it off. Of course, you can achieve the same
       effect by using regular expressions, as explained above.	But using the
       links attribute makes your code cleaner.

       There are several arguments (in an array	reference) you can supply to
       the links attribute.

       The number 1 turns on all default links and 0 will remove them.

       For example, to remove the default links	in the info_all	method,	you
       would say:

	       $p->info_all( links=>[0]	); # contains no links.	Good for printing!

       The example above removes all default links and it even ignores the
       link parameter in the print_modules method of HTML::Perlinfo::Modules.

       The named parameters for	the links attribute are	'docs' and 'local'
       which controls links associated with modules, programs in the Perl
       utilities section, and the Config section and everywhere	else. The
       value for either	parameter can be either	'1' or '0'.

	   Using 'docs', you can control the display of	the default links to
	   module and program documentation on	But the	link
	   parameter in	HTML::Perlinfo::Modules	can override this directive.
	   By overridding 'docs=>0', you can show documentation	for certain
	   modules and not show	documentation for any others. This is useful,
	   for example,	when you have homegrown	modules	without	any
	   documentation but want to show links	to documentation for CPAN
	   modules on the same page. Observe:

		   $p->print_modules( links => [docs=>0], link => [qr/Apache::/, ''] );

	   In the above	example, only links to Apache modules would appear.
	   Other modules would not have	links to any documentation. Note that
	   had you simply set the value	for links to zero, then	the other
	   attribute concerning	Apache modules would have been irrelevant,
	   since no links whatsoever would have	appeared. In other words, you
	   can mix and match these two atttibutes to achieve many different
	   and wonderous effects. Have fun! Be imaginative!

	   For more information	on print_modules and its link parameter,
	   please see HTML::Perlinfo::Modules.

	   With	the 'local' parameter set to 1,	the local location of a	module
	   or program will be a	link. This is useful if	you want to see	the
	   local installation directory	of a module in your browser. (From
	   there, you could also look at the contents of said files.)

	   Note	that this link would only work if you use the perlinfo library
	   from	the command-line and then view the resulting page on the same
	   machine. Hence these	local links are	not present by default.

	   You can even	use 'docs' along with 'local'.

		   $p->info_all( links => [docs=>0,local=>1] )

       HTML::Perlinfo::Modules allows you to color code	specific modules.

       More HTML options should	be available in	future revisions. Want to see
       a new feature/change? Then contact me about it.
