Clojure has a new core library, clojure.spec, that aims to provide a standard and integrated system for the specification and testing of data and functions. Besides making it possible to automatically validate Clojure code, the new specification system can be used for a number of tasks such as generative testing, error reporting, and destructuring.
Earlier this month, Alex Miller, one of the main developers behind the Clojure Community, announced the latest version of Clojure. The flagship new features of Clojure 1.8 are Direct Linking, String Functions and Socket Servers, although it also includes a few minor enhancements and more than thirty bug fixes.
Clojure development on the Android platform has been progressing remarkably in the last few years, allowing developers to use it in fully fledged apps such as SwiftKey’s Clarity Keyboard. Here we will review the current status of tools that support Clojure on the Android platform.
Glenn Vanderburg, director of engineering at LivingSocial, gave an interesting recount of his effort to implement TeX’s algorithms in Clojure at the last ClojureConj conference. In the process, he discovered how much programming has changed in the last thirty years.
Cognitect has recently published the results of a community survey aimed at finding out "how and for what Clojure and ClojureScript are being adopted, what is going well and what could stand improvement." According to Cognitect, though not a scientific survey, it shows how Clojure has "transitioned from exploratory status to a viable, sustainable platform for development at work."
In a recent article, Alex Payne, organizer of the Emerging Languages Camp, provides insight on how the language landscape has changed in the last five years and how it might change in future. InfoQ has talked with him.
Prismatic have added data coercion in the 0.2 release of their Clojure data description library, Schema. The addition of coercion means that the library doesn’t just reject data that has the wrong types, but it can be configured to modify instances to fit the schema. InfoQ talked to Prismatic's Jason Wolfe about Schema.
Chris Granger has open sourced the LightTable IDE with the 0.6 release. Third party plugin support was the highlight feature of the release. InfoQ talked to LightTable creator Chris Granger.
Om is a new a ClojureScript interface for Facebook’s React HTML UI library. Om uses Clojure(Script)'s persistent data structures and requestAnimationFrame to further improve React's rendering. InfoQ talked to Om's creator, David Nolen, about Om and the benefits of functional concepts for application programming.
It's one thing having an in-house training program. But there is a certain deeper insight that can be gained from attending a Q-Con conference in person. Which may be one reason why attendance at the globe-hopping event continues to grow.
On each day of the 3-day conference at the inviting environs offered at the Hyatt there was a jam-packed schedule of speakers, exhibits and activities that made for some difficult decisions as to which tracks and what happening to attend.
core.typed adds an optional type system to Clojure, aiming to combine the best of both worlds: the brevity and flexibility of Clojure and the safety guarantees that a type-checker provides.
While it has been less than a month since the announcement of the core.async Clojure/ClojureScript library, a number of blog posts have been published describing how to use it effectively to avoid "callback hell" in front-end code, and showing off simple code resulting in some impressive demos.
