What's new on CPAN - June 2016

Jul 13, 2016 by David Farrell

Welcome to “What’s new on CPAN”, a curated look at last month’s new CPAN uploads for your reading and programming pleasure. June saw YAPC::NA (among other conferences) which meant CPAN activity was lower than normal. I’m expecting a bumper July though; for now enjoy!

APIs & Apps

• App::Licensecheck inspects source files for licenses
• Use the Runkeeper (Health Graph) API with WebService::HealthGraph
• WebService::SQLFormat formats SQL via the sqlformat.org API
• Monitor the status of other plack applications using Plack::App::ServiceStatus

Config & Devops

• In the docs for Acme::Devel::Hide::Tiny author David Golden shows how to force the unavailability of a module for testing without adding a test dependency
• Get a single list of all dependencies (including indirect ones) for a distribution with CPAN::Flatten

Data

• DBIx::EAV enables Entity-Attribute-Value data modeling (aka ‘open schema’) via DBI
• Useful testing tool: generate random IPs with IP::Random
• Estimates the length of all the vectors in an SVG file using SVG::Estimate
• String::Normal is another text normalization module
• Extract strings from markup with XML::Lenient
• Get convenient, fast and jQuery-like DOM manipulation with XML::LibXML::jQuery

Development & Version Control

• Use U2F authentication with your app using with Authen::U2F
• PDF::PDFUnit Perl interface to the Java PDFUnit testing framework
• The Parallel::Dragons abstract says “Daemon are forever… Dragons lay eggs, grow fast and die in flames!”
• Useful Perl::Critic policies:
  • Perl::Critic::Policy::Moo::ProhibitMakeImmutable checks that Moo classes do not contain calls to make_immutable á la Moose
  • Perl::Critic::Policy::TryTiny::RequireBlockTermination checks that try/catch/finally blocks are properly terminated - this is so easy to get wrong and the error message is often cryptic.
  • Perl::Critic::Policy::TryTiny::RequireUse checks that code which uses Try::Tiny actually imports it
• Do meta programming with Sub::Attributes (disclosure - I am the module author)

Hardware

• Medical: a SLURM-specific driver for HPCI using HPCD::SLURM
• New chip drivers:
  • Device::Chip::PCF8574
  • Device::Chip::SSD1306

Other

• Solve for the WordBrain mobile Game with Game::WordBrain
• Ham radio enthusiasts:
  • Ham::WSJTX::Logparse parses ALL.TXT log files from Joe Taylor K1JT’s WSJT-X, to extract CQ and calling station information for all entries in a given amateur band
  • Ham::WorldMap creates an Imager image containing an equirectangular projection of the world map, with optional Maidenhead locator grid and day/night illumination and additional utility methods

Science & Mathematics

• Math::BivariateCDF provides Bivariate CDF functions

Web

• Interesting: Mojo::UserAgent::CookieJar::ChromeMacOS can read OSX Chrome Chrome cookies for Mojo::UserAgent
• Scrape the FindaGrave site using WWW::Scrape::FindaGrave
• Weasel let’s you use a single module for different web drivers like Selenium. Inspired by PHP’s Mink
