NonGNU-devel ELPA - cider

Provides a Clojure interactive development environment for Emacs, built on
top of nREPL.  See https://docs.cider.mx for more details.

Changelog

master (unreleased)

New features

• #4142: Bring CIDER's dynamic font-locking (highlighting REPL-defined macros, functions, vars and deprecated/instrumented/traced symbols) to clojure-ts-mode buffers via tree-sitter; previously it only worked under clojure-mode.
• #4145: Add cider-preferred-clojure-mode (default auto) controlling which Clojure major mode CIDER uses to font-lock the code it renders (REPL input/results, doc examples, overlays, xref labels, etc.); when set to (or auto-detecting) clojure-ts-mode, those snippets get tree-sitter highlighting instead of clojure-mode's.
• #4146: Have CIDER's own Clojure display buffers (macroexpansion, evaluation results, tracing) honor cider-preferred-clojure-mode too, so they open in clojure-ts-mode when that's your preference instead of always clojure-mode.
• #4143: Highlight the #break/#dbg/#light debugging reader tags in clojure-ts-mode buffers too.
• #4117: Add cider-use-completing-read-for-symbol (off by default): when enabled, symbol prompts (e.g. cider-doc, cider-find-var) read through completing-read over a lazy, runtime-backed collection, so they work with completing-read UIs (Vertico, Ivy, Helm) and annotate candidates with their type and namespace.
• #4129: Render completion annotations as an aligned type/namespace column (via an affixation-function) in UIs that support it, such as the built-in *Completions*, Corfu and Vertico.

Changes

• #4149: Make the nREPL message log easier to reach: add "Show nREPL messages" to the nREPL menu, reflect the logging toggle's on/off state there, and have nrepl-show-messages offer to enable logging when it's off instead of erroring.

Bugs fixed

• #4152: Stop the dynamic font-lock locals scanner from treating the default expressions in an :or destructuring clause (e.g. {:keys [x] :or {x (some-default)}}) as local variables, so references there keep their normal highlighting.
• #4150: Stop dropping stray output from long-lived background processes (e.g. a core.async go-loop still printing under a finished eval's id): once that id is evicted from the completed-requests cache, its out/err is now routed to the REPL instead of being discarded with a "No response handler with id N found" warning.
• #4140: Fix cider-eval-dwim (and defun evaluation) not descending into a (comment ...) form in clojure-ts-mode buffers: it now binds clojure-ts-toplevel-inside-comment-form alongside the clojure-mode variable.
• #4139: Fix source-based find-usages (M-?) missing alias- and namespace-qualified references (e.g. m/foo), so a var used through its alias from other namespaces is now found, not just the bare occurrences in its defining namespace.
• #4136: Fix a custom ClojureScript REPL init form being sent unwrapped when it starts with a call like (dorun ...) or (doseq ...), which the previous (do prefix check mistook for an existing do block.

2.0.1 (2026-07-23)

Changes

• #4116: Bump the injected cider-nrepl to 0.62.2, so a dead trace/tap subscriber no longer breaks every traced evaluation, and the debugger no longer shadows the enlighten middleware's evaluator. ... ...
