Password::Policy::Rule::Pwned Plug matches against api.pwnedpasswords.com into Password::Policy

Password::Policy::Rule::Pwned is a Password::Policy::Rule to match against the pwned password service at https://api.pwnedpasswords.com/range/ as specified at https://haveibeenpwned.com/API/v2#PwnedPasswords

A password found in the list throws an exception as usual. A password not in the list returns itself also as usual.

Following discussions with the author of Password::Policy, it has been decided to throw a separate, distinct, testable error to deal with the 3rd possibility which is a failure in the API call for whatever reason.

LDF::Schema Classes that implement Linked Data e.g. schema.org

I am working on some Perl classes that are auto-generated from http://schema.org class definitions, and can then be used to output json-ld metadata appropriate to the classes (e.g. for embedding in a web page to help search engines index the content).

Eventually I hope to add classes for other data schemes (e.g. "dc", "foaf" etc.) and allow them to be combined.

In the mean time, I am unsure what to call the module. I chose the "LDF::" namespace since it relates to linked data fragments, but I'm not happy with that. I am open to suggestions.

HTML5::DOM Make html parsing fast again

Stop using libxml for parsing html!

HTML5::DOM - is a fast HTML5 parser with DOM and CSS4 selectors. It really fast, as rocket. With threads!

At the same time, it is achieved fully conformant with the HTML5 specification.

Module has simple classic DOM-like API, it's easily to use. Try and enjoy!

Why this module so fast?

Module written in pure C and based on Modest and MyHTML.

Apache::Arrow Perl bindings for Arrow data structures, IPC and computation kernels

Apache Arrow https://en.wikipedia.org/wiki/Draft:Apache_Arrow already has C bindings via GLib https://github.com/apache/arrow/tree/master/c_glib and Perl already has GLib bindings via https://metacpan.org/pod/Glib.

Given this, does it make sense to implement Arrow bindings for perl as its own module? Or are the existing GLib bindings sufficient for any practical task?

If I were to implement Apache::Arrow[::*] it would likely be little more than a convenience wrapper around the GLib interface.

Amazon::Credentials read AWS credentials from file, instance metadata, container, env

While PAWS is a wonderful project, it has a lot of dependencies. I've found myself trying to use slimmer Perl modules for interacting with AWS...along the way a need arises to provide the AWS credentials tuple, hence Amazon::Credentials which attempts to find those in the various places they should be found.

Might be a module somebody needs, might not. So, some questions for the community:

  • Do folks want a slimmer set of AWS APIs or is alignment with boto3 more important?
  • Does anyone still use some of the AWS CPAN modules or is all development being down with PAWS?
  • Any feedback on the module in any event would be appreciated.

Web::Mention An implementation of the Webmention protocol, as defined by the W3C and the IndieWeb community.

This set of modules implements Webmention, according to its W3C-defined spec as well as related best practices developed by the IndieWeb community.

About Webmention

Webmention provides a standard way for one website to inform another that someone, somewhere on the web, has published a reference to a URL under the receiver's domain. This notification travels through very short and simple HTTP POST messages that merely identify the two URLs involved: the source of the mention, and its target. The receiver of a webmention can, at its own leisure, request the HTML document found at the source URL in order to verify the mention, and also to learn more about its author and content via any Microformats2 metadata it may contain. The receiver may then proceed to do something interesting with this fetched and parsed data, such as display hyperlinked information about the mention and its author underneath its own, original content.

For example, a response published on Blog A to an article on Magazine B could result in A sending a webmention to B. (There is implied consent here, since the article on B has a <link> tag in its HTML that explicitly invites webmentions, providing an endpoint URI for them.) It would then become B's responsibility to confirm that the webpage at A really does mention the URL of B's aticle. B may then wish to represent the mention on its own site, however it deems appropriate.

About these modules

An object of the main Web::Mention class represents a single webmention instance, probably created from an incoming HTTP request, as shown in the synopsis. The object's verify() method (and, indeed, its is_verified attribute) will do the hard work of fetching the source URL's document, verifying the presence of the target URL, and parsing any Microformats2 metdata it finds in order to infer author information. The latter goes into a Web::Mention::Author object, and taken all together this should give the receiver enough information to react in some appropriate way to the mention.

This module requires Web::Microformats2, another proposed CPAN module of mine with its own PrePAN page.

Near-future versions of this module will assist with creating and sending webmentions. But receiving is the harder part (and arguably the more rewarding part as well) so I wanted to get it done first. This ended up being a depth-first adventure that resulted in my creating all of Web::Microformats2 before I could come back and finish this module, and so here we are.

Regarding the name

I'd like to hear opinions on the name. Giving it a top-level namespace of "Web" seemed natural, for the same arguments I made in Web::Microformats2's case, and then following up the way I did seemed inevitable. But is splitting the word up this way too "cute"? Or, more to the point, will it make it harder to find in CPAN searches?

Certainly "Web::Webmention" is too ugly to live, but I could be talked into e.g. "Net::Webmention" or "HTTP::Webmention" or something. Absent any argument to the contrary, I do like both the directness and the subtle humor of "Web::Mention" the best.

Web::Microformats2 Libraries for parsing Microformats2 metadata from HTML or JSON

From the repository's own README:

The Web::Microformats2 modules provide Perl programs with a way to parse and analyze HTML documents containing Microformats2 metadata. They can pull Microformats2 information from a given HTML document, representing it as a queryable in-memory object. They can also serialize this object as JSON (using the Microformats2 rules for this), or read an already JSON-serialized Microformats2 structure for further analysis.

Why a new module, when CPAN already has three Microformats modules?

CPAN already has HTML::Microformats, Text::Microformat, and Data::Microformat. However, putting aside the fact that the most recent of these was last updated five years ago, they all deal with the original iteration of the Microformats standard. The module I propose, Web::Microformats2, specifically and exclusively addresses Microformats2, a wholly new specification.

Microformats2 is related to its similarly named predecessor in general intent, but its design philosophy and implementation are quite different. As such, software that parses Microformats2 metadata will necessarily be completely separate from that which parses Microformats(1).

Yes, this is a little confusing. I wish it were less so. But that's why my proposed name for this module is "Microformats2": it's simply and literally what the underlying standard calls itself, for good or ill.

Why "Web" when it deals primarily with HTML and JSON input/output?

My motivation for creating these modules is the IndieWeb movement, which uses Microformats2 as a common standard throughout its many proposals and specifications. I wish to implement certain IndieWeb standards in Perl, and that requires Perl's ability to parse Microformats2 metadata, both as found in HTML documents and as pre-processed JSON.

By filing this modules under the "Web" top-level namespace, I hope to signal their usefulness to the ideal of the open web, specially that as espoused by the IndieWeb movement. In this sense, the specific technologies involved (including HTML and JSON) are less important than the philosophies that hope to bring about a more open web, overall.

And, yes, more practically: were I to name this "HTML::Microformats2", I'm afraid that would imply it to be version 2 of Toby Inkster's HTML::Microformats, which it is not. It serves a wholly distinct purpose from those older modules, and I think it ought to have an appropriately distinct name within the CPAN.

Zcash::RPC::Client Zcash Payment API client as a Perl module

This module is a pure Perl implementation of the methods that are currently part of the Zcash Payment API client calls (zcash-cli). The method names and parameters are identical between the Zcash Payment API reference and this module. This is done for consistency so that a developer only has to reference one manual: https://github.com/zcash/zcash/blob/master/doc/payment-api.md

Zcash is based on Bitcoin. Zcash supports all commands in the Bitcoin Core API (as of version 0.11.2). This module is a fork of the Bitcoin JSON-RPC client (Bitcoin::RPC::Client) from Wesley Hinds.

Term::CLI CLI interpreter based on Term::ReadLine

Implement an easy-to-use command line interpreter based on Term::ReadLine and Term::ReadLine::Gnu.

First-time users may want to read the documentation for Term::CLI::Tutorial and Term::CLI::Intro first, and peruse the example scripts in the source distribution's examples and tutorial directories.
