Whatpm (beta)

Introduction

Whatpm is a work-in-progress set of Perl modules for Web hypertext application technologies. It is part of the manakai project.

Modules

Whatpm::ContentChecker

A DOM5 HTML (in-memory representation of a document) conformance checker with a partial support for Atom 1.0. (See also demo.)

Whatpm::ContentType

An implementation of HTML5 Content Type sniffing algorithm.

Whatpm::CSS::SelectorsParser

A group of selectors parser. (See also demo.)

Whatpm::CSS::SelectorsSerializer

A group of selectors serializer. (See also specification and demo.)

Whatpm::CSS::Tokenizer

A CSS tokenizer. (See also demo.)

Whatpm::HTML

An implementation of HTML5 parsing algorithm, fragment parsing, and fragment serialization algorithms. It can be used to convert a string into DOM, or vice versa. (See also demo.)

Whatpm::HTMLTable

An implementation of the HTML5 table algorithm. It can be used to extract a table structure from a DOM table element node. (See also demo.)

Whatpm::IMTChecker

An Internet Media Type (aka MIME type) label conformance checker.

Whatpm::URIChecker

An IRI reference conformance checker.

Whatpm::XMLSerializer

A simple XML serializer.

Note that all of these modules are work in progress and have a number of unresolved problems.

Note also that some modules have no documentation for now.

Specification

SSFT Specification

The specification for the serialization format used for testing Selectors-related modules.

manakai's Selectors Extensions

The specification for :-manakai-* pseudo-classes implemented by Selectors-related modules.

Documentations

List of error types

Description of errors to be notified to callback functions by Whatpm modules.

Selectors object

Description of data structure of Selectors object as used by Whatpm::CSS::SelectorsParser (as output), and Whatpm::CSS::SelectorsSerializer (as input).

Demo

• HTML5 parser and checker demo (source, with a lightweight non-conforming DOM implementation)
• HTML5 parser and checker demo, with manakai's DOM implementation (source)
• HTML5 table structure visualization demo (source)
• CSS tokenizer demo (source)

Dependency

Perl 5.8 or later

It is recommended to use newer release of Perl 5.8 or later.

Message::IMT::InternetMediaType

Whatpm::IMTChecker depends on Message::IMT::InternetMediaType, which is part of manakai.

Message::URI::URIReference

Whatpm::URIChecker depends on Message::URI::URIReference, which is part of manakai.

manakai charlib

Whatpm::Charset::DeocdeHandle depends on modules in manakai charlib for decoding Japanese character encodings. See the documentation for manakai charlib for more information.

Message::DOM::DOMImplementation and related modules

Testing for Whatpm::ContentChecker depends on Message::DOM::DOMImplementation and related modules in manakai. They are not required in practice.

JSON

Testing for Whatpm::HTML and Whatpm::CSS::Tokenizer depends on JSON and related modules. They are not required in practice.

Distribution

The development version of Whatpm may be found in the CVS repository.

TO DO

• Bug fix (Test results: Whatpm::ContentType, HTML tokenization, HTML tree construction, Whatpm::ContentChecker).
• Charset detection.
• Validation for meta.
• Validation for media queries, IRIs (against URI schemes), language tags, and so on.
• Documentations are missing for some features.
• XML parser.
• In addition, each module has its own TO DO items. (Search for ## TODO and ## ISSUE in each module.)
