Projectile 3.4 is out! After the four releases that preceded it this summer, this one is polish rather than ambition. Most of it came out of an annoyance I’d been living with for years without ever quite naming it: a lot of what I work on i…
RuboCop 1.89 is out, and it comes with the usual assortment of new cops and bug fixes. But there’s one theme running through this release that I’m particularly excited about, and that’s what I want to talk about today: RuboCop is finally le…
Continuing the series on the notable changes in CIDER 2.0, let’s talk about ClojureScript - forever the trickier sibling in the CIDER family. I’ll start with a confession I’ve made before: I rarely use ClojureScript myself, which is a big p…
The series on the notable changes in CIDER 2.0 rolls on. This time: the “what is my code actually doing?” toolbox - the debugger, tracing, enlighten, and the new tap viewer. This was the part of the release I enjoyed working on the most, an…
