• Remove a misplaced error message when doing clojuredocs-lookup.
• #2721: Handle properly symbols ending in . (e.g. SomeRecord.).

CIDER 0.22 (São Paulo)

New features

• #2656: Base64 encode clojure command and arguments on jack-in when cider-clojure-cli-command is "powershell" to avoid escaping issues. If no clojure command is found on Windows cider-clojure-cli-command defaults to "powershell".

• spec-list and spec-form requests send the current namespace for alias resolution.
• C-c , C-g and C-c C-t C-g cancel the key chord instead of rerunning the last test. The respective command has been moved to C-c , C-a, C-c , a, C-c C-t C-a and C-c C-t a.
• #2643: (Breaking) Stop using the cider.tasks/nrepl-server custom task for cider-jack-in with Boot.

• #2689 cider-load-file-handler now takes an optional done-handler lambda that is run once load is complete.

Bug fixes

• #2685: Send exclude-regexps in apropos under correct key
• Stop cursor moving when initialising the CIDER REPL, when cider-repl-pop-to-buffer-on-connect is nil. This fixes a bug introduced by commit e0aca78b.
• #2577: Ensure user friendly error messages if a repl connection is expected but none was found in certain situations.
• #2593: The REPL's initial namespace is now set correctly if configured in another tool (e.g. Leiningen's :init-ns).
• #2607: Use markers for specifying insertion point for cider-eval-*-to-commentcommands. This fixes a bug where editing the buffer during a pending evaluation resulted in comments appearing in unintended locations.
• #2308: Don't rely on the classpath in cider-library-present-p. Now it does a require instead to check if some library is present or not.
• #2541: Hook properly CIDER's code completion machinery.
• #2659: Handle #shadow/env reader tags in cider--shadow-get-builds.
• #2676: Widen before cider--file-string, to allow cider-load-buffer to work on narrowed buffers.
• Don't disable cider-mode until all CIDER sessions have been closed.

CIDER 0.21 (New York)

New features

• The cider-test-run-* and cider-ns-refresh-* commands are now interruptible by the cider-interrupt command.
• Many commands now stream printed results back to the client incrementally – meaning it's now possible to, for example, interrupt evaluations while their result is being rendered.
• New option: cider-repl-init-code. This is a list of strings containing Clojure code to evaluate when the REPL starts (with bindings for any set!-able vars in place). Replaces cider-print-length and cider-print-level, which are now obsolete.
• New option: cider-print-quota. This is a hard limit on the number of bytes that will be returned by any printing operation. This defaults to one megabyte and can be set to nil if no limit is desired.

Changes

• (Breaking) Upgrade to nREPL 0.6.0. This is now the minimum required version.
• (Breaking) Upgrade to piggieback 0.4.0. This is now the minimum required version.
• (Breaking) Remove cider.nrepl.middleware.pprint. All functionality has been replaced by the built-in printing support in nREPL 0.6.
• Option cider-repl-scroll-on-output is now obsolete, and the default REPL behaviour has changed to not recenter the window. The built-in variable scroll-conservatively can be set to 101 (either globally or locally in the REPL buffer) to restore the old behaviour. This change has a dramatic positive effect on REPL performance.
• cider-pprint-fn and cider-pprint-options are now obsolete, replaced by cider-print-fn and cider-print-options.
• cider-debug-print-options, cider-stacktrace-print-options, and cider-repl-pretty-print-width are now all obsolete, replaced by cider-print-options.
• #2546: New defcustom cider-ns-save-files-on-refresh-modes to control for which buffers cider-ns-refresh should save before refreshing.

Bug fixes

• Fix values for cider-preferred-build-tool variable.
• Fix value and safe property for cider-allow-jack-in-without-project variable.
• cider-ns-save-files-on-refresh will now save any modified buffers visiting files on the classpath, rather than just in the current project.
• cider-expected-ns no longer requires an absolute path as its argument, and now internally handles paths canonically and consistently.
• Fixed a bug causing REPL output to be inserted after the prompt.
• Fixed a bug causing cider-pprint-eval-last-sexp-to-comment and cider-pprint-eval-defun-to-comment to not insert anything.
• cider-find-var now correctly uses a new window when passed a prefix of - or a double prefix argument.
