Clojurians Log v2

On Firefox, the company logos look a bit weird, some having dark lines on the main page in dark mode.

https://github.com/clj-kondo/clj-kondo: static analyzer and linter for Clojure code that sparks joy ✨ 2026.10.20 • NEW linter :unknown-map-key: warn on a keyword lookup of a key not present in a map. E.g. (:hots (opts)) will warn when opts returns {:host "localhost"}. • Catch up with Clojure 1.13.0-alpha9 destructuring • https://github.com/clj-kondo/clj-kondo/issues/2942: Analysis: a keyword after & in 1.13 :keys destructuring is a plain keyword. E.g. :foo in {:a/keys [& :foo]}. • Type checker: a type predicate narrows the type of a local in if-not, cond and and. E.g. (when (and (string? x) (pos? n)) (inc x)) will warn. • Type checker: merge and merge-with require a map or nil as first map argument. E.g. (merge [1 2] [3 4]) will warn. • Type checker: a :keys arg spec checks each map of a union argument. E.g. (g (if x {:id 1} {:id 2})) will warn when g requires key :id to be a string. • Type checker: a keyword lookup on a map return that may be nil includes nil. E.g. (inc (:a (f x))) with (defn f [x] (when x {:a "s"})) will warn. • https://github.com/clj-kondo/clj-kondo/issues/3002: fix Condition always true false positive for a :keys return spec with :nilable true • Type checker: fix :type-mismatch and :constant-condition false positives on maps from hook-generated code. E.g. defenterprise in metabase. • https://github.com/clj-kondo/clj-kondo/issues/2774: :warn-on-reflection also warns on Java constructor calls. E.g. (Date. x) will warn. • https://github.com/clj-kondo/clj-kondo/issues/2994: check arity of calls in protocol implementations and clojure.test/is against cached namespaces • https://github.com/clj-kondo/clj-kondo/issues/2956: fix :invalid-arity false positive for (map {}) • https://github.com/clj-kondo/clj-kondo/issues/3005: fix unresolved symbol in a self-referencing def when clojure.test is referred with :all • https://github.com/clj-kondo/clj-kondo/issues/2945: support :order-by, :having and :timeout in Datalevin and Datahike queries • https://github.com/clj-kondo/clj-kondo/issues/2947: config merging keeps the highest :min-clj-kondo-version (https://github.com/arimu1) • Hooks: a qualified symbol in hook output no longer needs a require in the calling namespace • https://github.com/clj-kondo/clj-kondo/issues/3006, https://github.com/clj-kondo/clj-kondo/issues/3014, https://github.com/clj-kondo/clj-kondo/issues/3015, https://github.com/clj-kondo/clj-kondo/issues/3016: fixes for hooks generated with :clj-kondo/macroexpand-hook: referred macros, helper namespaces, requires without alias and nested hooks (https://github.com/imrekoszo) • https://github.com/clj-kondo/clj-kondo/issues/2998: analyze Java 25 class files (https://github.com/skylightis666) • https://github.com/clj-kondo/clj-kondo/issues/2996: fix Java member analysis of a .java file with an enum in the native binary (https://github.com/skovati) • https://github.com/clj-kondo/clj-kondo/issues/2948: fix startup crash of binaries built with GraalVM 25.1+ • Bump SCI to 0.15.59

https://github.com/clojure-vim/vim-jack-in now has a :ClojureREPL command for clojure-cli.repl integration #C0C5YK5PAQ0

https://github.com/seancorfield/honeysql https://github.com/seancorfield/honeysql/releases/tag/v2.8.85 -- Turn Clojure data structures into SQL (the 85th release) Runs on Clojure 1.10+, ClojureScript, Babashka, Jolt, and let-go! • Exclude upper-case from clojure.core under let-go, where core defines that name, so requiring honey.sql no longer warns, via PR https://github.com/seancorfield/honeysql/pull/619 from https://github.com/abogoyavlensky. • Fix https://github.com/seancorfield/honeysql/issues/618 by ensuring column specifications in :insert-into, :patch-into, :replace-into, and :columns clauses are respected when formatting :values. This was a bug that was present in 2.4.1066 (three years ago) and brings the actual behavior in line with the documentation. • Change versioning scheme to MAJOR.MINOR.RELEASES. (because @lee showed me how much easier this is than using COMMITS!) • Update dev/test deps. Follow-up in #C66EM8D5H
