Welcome to the Clojure Deref! This is a weekly link/news roundup for the Clojure ecosystem. (@ClojureDeref RSS)


Rich Hickey wrote a paper "A History of Clojure" for the HOPL IV (History of Programming Languages) conference. This week the video for the conference was made available along with the Q&A hosted by Guy Steele. Certainly worth watching/reading if you want to know more about how and why Clojure came to be!

We got the sad news this week that the beloved 4Clojure site is shutting down. For a long, long time 4Clojure has been an early stop for many developers learning Clojure, as a source of programming problems, and perhaps more importantly as a font for answer comparisons. Many hearty thanks to David Byrne, Alan Malloy, and everyone that contributed to it over a decade of use. There are already a couple nascent efforts to bring it back to life in other forms if you want to help.

In the core

Today we put out a pre-release of the Clojure CLI and a new library covering many enhancements and new features for working with source libraries (particularly those from git), project builds, and CLI tools. Check out Source Libs and Builds for an overview and links to new docs! Feedback is welcome at or in the #tools-deps channel on Clojurians slack.
