What's new on CPAN - May 2015

Jun 4, 2015 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. Enjoy!

Module of the month

App::GitHooks::Plugin::ForceBranchNamePattern will enforce a branch naming pattern using a regex. Author Guillaume Aubert gives the use case of building a Puppet environment from Git branches (Puppet environment names must be alphanumeric). Another example is when you want all Git branch names to map to an issue tracker id.

Guillaume Aubert has developed many other useful Git hook plugins, such as emitting release messages into Slack and checking Perl code passes a Perl Critic review. Check them out!

APIs & Apps

• Disque is a distributed job queue built on top of Redis
• HPCI is an application for performing distributed computing
• Use the watcher plugin with Elasticsearch using Search::Elasticsearch::Plugin::Watcher
• WWW::Pocket provides an interface for the Pocket v3 API
• WWW::Marvel is an alpha-release interface for the Marvel comics API
• Looking for a faster XML library? TurboXSLT provides an interface to libturboxsl
• Net::Hadoop::YARN is an API for Apache Hadoop Next Generation
• Send Google Analytics user metrics from Perl using Net::Google::Analytics::MeasurementProtocol
• Net::Amazon::DirectConnect lets you interact with Amazon’s DirectConnect service
• Use the Airbrake Notifier API V3 Client with Net::Airbrake

Config & DevOps

• Config::Perl aims to be a safer alternative to loading Perl data structures than with eval by using PPI. Interesting approach, blackhat hackers start your engines…
• Group::Git::Taggers::Perl provides a way to detect Perl git repos. Could be a useful complement to GitHub’s API language detection
• Store SpamAssassin rules performance data in Redis using Mail::SpamAssassin::Plugin::RuleTimingRedis

Data

• Looking for a fast priority queue implementation? Check out Array::Heap::ModifiablePriorityQueue
• DBIx::Class::AuditAny is a configurable change tracking tool for DBIx::Class schemas. For example it could be used to track the changes of values in a table over time (insert, update, delete etc)
• Manage database relationships in DBIx::Class when the traditional route fails with DBIx::Class::Schema::Loader::DBI::RelPatterns
• DBIx::Class::InflateColumn::TimeMoment provides a DBIx::Class column handler for the super fast date time implementation
• Generate HTML from data using HTML::AutoTag
• With Sereal::Path you can use XPATH and JSONPath with Sereal-encoded data. Nice!

Development and Version Control

• Find out the reverse dependencies of a module with App::CPAN::Dependents. Has a neat command line option too
• Acme::AutoloadAll exports all subroutines from every loaded module by injecting an autoload function into them. Crazy!
• Keep your Dzil GitHub credentials in one place with Dist::Zilla::Stash::GitHub
• Data::Object::Prototype makes prototype-style programming easy. Interesting approach
• Create application locks based on files or sockets withJIP::LockFile and JIP::LockSocket
• List::Slice provides head and tail functions for lists, plays nicely with functions that output lists like map and grep
• Declare compile-time and class-safe constants with pluskeys

Hardware

• Device::GPS can read GSP NMEA data via serial port
• Device::GPIB::Prologix provides a Perly interface for the Prologix GPIB-USB Controller

Science and Mathematics

• Bio::CUA provides “comprehensive and flexible tools to analyze codon usage bias”. Looks impressive
• Bio::LITE::Taxonomy::NCBI aims to be a Lightweight and efficient NCBI taxonomic manager
• Dallycot is “an engine for running linked open code (algorithms expressed as linked open data) and exploring linked open data”
• Read and write Graph6 / sparse6 graph formats with Graph::Graph6
• HEP::MCNS can convert Monte Carlo numbers into particle names
• LCS::BV is a bit vector implementation (read: faster) of the LCS algorithm (used for diff among other things)
• Math::EWMA provides an exponential weighted moving average object

Web

• Catalyst::ActionSignatures allows declaration of variables in Controller signatures
• Dancer2::Plugin::Auth::HTTP::Basic::DWIW provides HTTP basic authentication for Dancer2 apps
• HTTP::Tinyish is a wrapper for the popular Perl HTTP modules (HTTP::Tiny, LWP etc) and will fallback to using the appropriate module for the request made
• IO::All::Securftp implements a secure FTP handler for IO::All
• Interact with the JavaScript in your Mojo applications using Mojo::Phantom. Cool!
