NAME

Graph::Easy::Pod2HTML - Render pod with graph code as HTML

SYNOPSIS

perl -MGraph::Easy::Pod2HTML=go -e 'go thingy.pod'

DESCRIPTION

Graph::Easy::Pod2HTML uses Pod::Simple::HTML to render POD as HTML. In addition to Pod::Simple::HTML, it also handles paragraphs of the type graph like shown here:

=for graph [ A ] => [ B ]

=begin graph

 [ A ] => [ B ] -> [ C ]
 [ C ] => [ D ]

=end graph

In addition to graph code, you can also use graph-common to store graph code that should be common to all following graphs. Each graph-common paragraph will replace the former definition:

This graph will have default settings:

=for graph [ A ] => [ B ]

Store now a different background color:

=begin graph-common

graph { background: #deadff; }
node { background: #fff000; }

=end graph-common

This graph will use the common part defined above:

=for graph [ A ] => [ B ]

This will replace the common parts with only a
blue background for nodes:

=for graph-common node { background: blue; }

So this graph will have blue nodes:

=for graph [ A ] => [ B ]

METHODS

new()

$converter = Graph::Easy::Pod2HTML->new();

Creates a new converter object, which takes pod and emit's HTML.

go()

$conveter->go( $filename );

Parse $filename and emit HTML on STDOUT.

CUSTOMIZATION

The following methods can be used to customize the appearance and the contents of the output of Graph::Easy::Pod2HTML:

$footer = $converter->footer_contents();	# query
$converter->footer_contents('');		# disable
$converter->footer_contents('Hello HTML!');	# set

This method let's you decide whether you want a final footer paragraph, or not, and what it should contain. The default is a timestamp and the version of Graph::Easy::Pod2HTML.

css_file

$converter->css_file('');			# none
$converter->css_file('base.css');		# base.css

This method can be used to set the name of an external stylesheet file that should be linked from the generated document.

EXPORT

Exports nothing, but can export go() on request.
