6 PPI::HTML - Generate syntax-hightlighted HTML for Perl using PPI
7
9 use PPI;
10 use PPI::HTML;
11
12 # Load your Perl file
13 my $Document = PPI::Document->load( 'script.pl' );
14
15 # Create a reusable syntax highlighter
16 my $Highlight = PPI::HTML->new( line_numbers => 1 );
17
18 # Spit out the HTML
19 print $Highlight->html( $Document );
20
22 PPI::HTML converts Perl documents into syntax highlighted HTML pages.
23
25 PPI::HTML is the successor to the now-redundant PPI::Format::HTML.
26
27 While early on it was thought that the same formatting code might be
28 able to be used for a variety of different types of things (ANSI and
29 HTML for example) later developments with the here-doc code and the
30 need for independantly written serializers meant that this idea had to
31 be discarded.
32
33 In addition, the old module only made use of the Tokenizer, and had a
34 pretty shit API to boot.
35
36 API Overview
37 The new module is much cleaner. Simply create an object with the
38 options you want, pass PPI::Document objects to the "html" method, and
39 you get strings of HTML that you can do whatever you want with.
40
42 new %args
43 The "new" constructor takes a simple set of key/value pairs to define
44 the formatting options for the HTML.
45
46 page
47 Is the "page" option is enabled, the generator will wrap the
48 generated HTML fragment in a basic but complete page.
49
50 line_numbers
51 At the present time, the only option available. If set to true,
52 line numbers are added to the output.
53
54 colors | colours
55 For cases where you don't want to use an external stylesheet, you
56 can provide "colors" as a hash reference where the keys are CSS
57 classes (generally matching the token name) and the values are
58 colours.
59
60 This allows basic colouring without the need for a whole
61 stylesheet.
62
63 css The "css" option lets you provide a custom CSS::Tiny object
64 containing any CSS you want to apply to the page (if you are using
65 page mode).
66
67 If both the "colors" and "css" options are used, the colour CSS
68 entries will overwrite anything contained in the CSS::Tiny object.
69 The object will also be cloned if it to be modified, to prevent
70 destroying any CSS objects passed in.
71
72 Returns a new PPI::HTML object
73
74 css
75 The "css" accessor returns the CSS::Tiny object originally provided to
76 the constructor.
77
78 html $Document | $file | \$source
79 The main method for the class, the "html" method takes a single
80 PPI::Document object, or anything that can be turned into a
81 PPI::Document via its "new" method, and returns a string of HTML
82 formatted based on the arguments given to the "PPI::HTML" constructor.
83
84 Returns a string, or "undef" on error.
