Notes.

No newsletter last week as I was on holiday, but this one is a bumper spec issue.

People are worried about Types. ?

I’m putting this section at the top this week, as there are several important spec related links.

• A lively thread on spec error messages
• Clojure 1.9.0-alpha11 is out which includes specs for clojure.core
• core.typed basics of automatic annotations, and inferring function types
• Om next and Bootstrapped ClojureScript
• Focus on spec: Combining Specs with and from Alex Miller

Foundations.

More spec, but this time in the foundational section, several papers that influenced spec’s design. David Nolen spoke on this at Papers We Love NYC, I’ll be sure to post the video if it was recorded.

• Parsing with Derivatives
• On the Complexity and Performance of Parsing with Derivatives
• Matthew Might talks about parsing with derivatives

Articles.

• I was sad to hear Yeller was shutting down
• Onyx raised $500k, congratulations!
• Daniel Higginbothams writing process
• Datomic’s log API

Learning.

• Tetris in ClojureScript with an impressive way to interact with the running code.
• Nathan Marz talking at ClojureNYC on inline caching to speed up Clojure programs

Libraries & Books.

• clojure.data.avl has a new release
• Shrubbery 0.4.0, a stubbing, spying, and mocking library for Clojure protocols
• re-frame has a massive new release out with a ton of cool features. I contributed to this release, and am really looking forward to seeing how people use it.

Tools.

• strace’ing a Clojure process under lein
• Leiningen 2.7.0 was released, managed-dependencies looks like it could be really useful.
• Funcjure (not yet released) brings infix notation to Clojure. Not to my taste, but interesting nonetheless.
• Cloverage has a new release thanks to LVH.

Misc.

• More black magic from Zach Tellman
