Clojure 2013 Year in Review

This is my third Clojure year-in-review post. In 2011 I was excited about Clojure 1.3, ClojureScript, and the second Clojure/conj. By 2012 I was blown away by four Clojure conferences, two O’Reilly books, reducers, Datomic, Immutant, and a partridge in a pear tree.

For 2013, where do I even start? So much has happened this year I can’t even begin to keep track of it all. What follows is my incomplete, highly-biased summary of the significant news for Clojure in 2013.

Growth and the Industry

Maybe I should start right here at my home base, Relevance, which, after years of close collaboration, finally tied the knot with Rich Hickey and Datomic to become Cognitect.

This merger opens up new possibilites with the introduction of enterprise-grade 24/7 support for Clojure, ClojureScript, Datomic, and the rest of the Clojure “stack.” Plenty of big businesses have been waiting for just this kind of safety guarantee before they jump into the Clojure open-source ecosystem, so this means we should be seeing Clojure in more, and bigger, places in 2014. Hear more on the transition episode of the Relevance Podcast, renamed the Cognicast.

In other industry / mindshare news:

Language & Contributed Libraries

Software & Tools

  • The Datomic team released Simulant for simulation testing of large distributed systems. See Stuart Halloway’s Simulant presentation on InfoQ.

  • Relevance/Cognitect released Pedestal, a client-server web toolkit to showcase the possibilities of Clojure on the server and ClojureScript in the browser.

  • nrepl.el became CIDER, the Clojure IDE and REPL for Emacs.

  • Chas Emerick’s Austin made ClojureScript REPLs easier to use.

  • New IDEs dedicated to Clojure appeared: Nightcode and Cursive for IntelliJ.

  • Prismatic released their Plumbing / Graph library as well as Schema for run-time type validation.

  • Immutant, a Clojure application server based on JBoss, made its 1.0 release.

  • Mark Engleberg released Instaparse, a parser generator that understands standard EBNF/ABNF notation.

  • I blogged about My Clojure Workflow, Reloaded, spawning dozens of experimental frameworks for doing dependency injection and modular programming in Clojure, including my own Component.

Blogs and ‘Casts

Tons more interesting stuff happened in 2013. I couldn’t even begin to capture it all in one place. Here are some other good places to look for interesting Clojure news:

Here’s to a great 2014!

    On the vim side of the aisle, vim-foreplay also became vim-fireplace, vim’s answer to CIDER
