Changelog

master (unreleased)

New features

• #3645: Show a spinner in the mode line while tests are running.
• #3865: Add default session feature to bypass sesman's project-based dispatch (cider-set-default-session, cider-clear-default-session).
• Introduce cider-jack-in-tools and cider-register-jack-in-tool so third-party packages can register new project tools for cider-jack-in and cider-jack-in-universal.
• Cache the result of cider--running-nrepl-paths (used by cider-locate-running-nrepl-ports) for cider-running-nrepl-paths-cache-ttl seconds (default 5). Repeated cider-connect completions no longer re-spawn a fresh round of ps/lsof subprocesses each time. cider-clear-running-nrepl-paths-cache discards the cache on demand.
• New nrepl-make-eval-handler with a keyword-arg API (:on-value, :on-stdout, :on-stderr, :on-done, :on-eval-error, :on-content-type, :on-truncated). Sub-handlers no longer take a buffer argument -- they close over whatever they need. nrepl-make-response-handler, the legacy 7-positional-arg form, is preserved as an obsolete shim that adapts the old (buffer x) lambdas to the new (x) lambdas, so existing extensions keep working.
• Decouple the nREPL transport layer from CIDER's UI layer (closes #1099). nrepl-make-eval-handler is now CIDER-agnostic: it no longer references nrepl-namespace-handler-function, nrepl-err-handler-function, nrepl-need-input-handler-function, or any hardcoded UI strings. New :on-ns and :on-status keyword slots let any consumer wire up their own namespace tracking and status handling. The editor-level cider-make-eval-handler wraps it with CIDER's UI behavior (ns tracking, default error handler, need-input prompt, "Evaluation interrupted." / "Namespace not found." messages); in-tree callers all use it.

Bugs fixed

• #3209: Fix cider-format dropping non-map cljfmt options (e.g. remove-consecutive-blank-lines?).
• cider-jack-in-clj now restores the originating buffer when running its connect callback, matching the behavior of cider-jack-in-cljs and cider-jack-in-clj&cljs.
• cider-locate-running-nrepl-ports now runs its ps/lsof probes via process-file, so endpoint completion for cider-connect works correctly from a TRAMP buffer (it inspects the remote host instead of the local one). Same for the lsof health check on .nrepl-port files.
• cider-clojure-cli-command and cider-jack-in-default no longer freeze their auto-detection result at package load time. With the new nil default, CIDER picks the right command/tool at jack-in time, so installing Clojure (or moving it on PATH) no longer requires restarting Emacs.
• cider--update-project-dir no longer reuses a single *cider-context-buffer* across calls. Each invocation gets a unique hidden buffer, so concurrent or interrupted jack-ins don't stomp each other.
• nrepl-server-filter now treats wildcard/loopback printed bind addresses (localhost, 127.0.0.1, 0.0.0.0, ::1, ::) as "use the calling context", so jacking in over TRAMP to a server that prints localhost connects to the TRAMP host instead of the local machine.
• cider--resolve-command now actually verifies command presence on remote hosts via executable-find's remote search, instead of unconditionally trusting the user-supplied command. A missing tool on the remote side now surfaces immediately during jack-in instead of as a server-startup failure later.
• nrepl--ssh-tunnel-connect no longer routes its ssh invocation through a shell. The tunnel command is now spawned via start-process with an explicit arg list, eliminating shell-quoting hazards in user/host components.
• Plug five request-id leaks in raw nREPL response handlers (cider/test-stacktrace, cider/test-var-query, cider/analyze-last-stacktrace, cider/ns-reload, cider/get-state). They never called nrepl--mark-id-completed, so their ids accumulated in the connection's nrepl-pending-requests for the lifetime of the session. ... ...
