By now probably most Rubists have heard of Prism (formerly know as YARP), the modern and (very) fast Ruby parser that’s aiming to replace all the existing Ruby parsers out there. Including RuboCop’s “own” parser (a.k.a whitequark/parser), which aimed to replace…

Today I’ve released nREPL 1.1.1 with a couple of small bug-fixes and one more notable, if mostly invisible change. Historically nREPL’s completions op used internally a modified version of clojure-complete, that I eventually released as a library named incomplete.…
