What's new on CPAN - September 2015

Oct 1, 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

MsgPack::RPC is a client for the MessagePack-RPC standard. It’s fully featured, providing send, notify, event subscription and logging.

Module author Yanick Champoux has blogged about his motivations for developing MsgPack::RPC to use it with Neovim. His entertaining musings are a good read. Now you can get an API to Neovim using his other new module, Neovim::RPC. Awesome work!

APIs & Apps

• API::Client is a general-purpose API client class
• Get simple OATH authentication with App::OATH
• App::p5stack manages your dependencies and Perl requirements in a local directory. Looks useful for standalone projects, packaging etc
• Net::PhotoBackup::Server - everyone backs up their photos right?
• Rarbg::torrentapi is a Wrapper around Rarbg torrentapi
• WWW::Zotero provides a Perl interface to the Zotero API
• WebService::Scaleway is a Perl interface to Scaleway, the cloud VPN provider

Config & Devops

• Config::Station looks interesting: class-based; it can load configurations from files and the environment

Data

• Log all DBI queries with DBI::Log. Awesome!
• DBIx::TempDB creates temporary databases for testing - supports Postgres, MySQL, SQLite
• Render data structures for easy grepping using Data::Crumbr
• Diachronic collocation index using DiaColloDB. Don’t know what this is, but it looks interesting.
• Image::JpegMinimal creates JPEG previews without headers.
• MarpaX::RFC::RFC3987 parse and validate IRIs with this Marpa module
• Message::String a “pragma” to declare and organise messaging.
• Brat::Handler is a Perl module for managing Brat files.

Development & Version Control

• Class::Anonymous get private classes with private data “for realz”.
• This looks like a useful analysis tool; Devel::Trace::Subs tracks code flow and stack traces.
• Do acceptance testing for JSON-Schema based validators with Test::JSON::Schema::Acceptance
• Yes!! Retry test functions on failure using Test::Retry

Hardware

• Perl extension for Device::Modem::SMSModem
• A driver for the Pertelian X2040 USB LCD with Device::Pertelian

Other

• Easily tie database data to Gtk2 / Wx based apps using Gtk2::Ex::DbLinker::DbTools
• Eliminate an entire email thread with Mail::ThreadKiller

Science & Mathematics

• Image::Libpuzzle provides a Perl interface to libpuzzle - the image similarity library
• Bio::Tradis can Bio-Tradis contains a set of tools to analyze the output from TraDIS analyses
• Manipulate RGB tuples with Number::RGB
• Time::Date appears to be the simplest date time implementation in Perl yet. I wonder what the limitations are?

Web

• Create a JSON View that owns its own data with Catalyst::View::JSON::PerRequest
• Add templates to the Data Section of Catalyst views using Catalyst::View::MicroTemplate::DataSection
• Replay terminal captures in your Dancer app using Dancer::Plugin::Showterm
• Future::Mojo let’s you use futures with Mojo::IOLoop. Very cool!
• The arms-race for faster continues! Replace HTTP::Headers and HTTP::Headers::Fast with HTTP::XSHeaders
