CIDER 0.9

New features

• #1109 New defcustom cider-auto-mode.
  On by default, when nil don't automatically enable cider-mode in all Clojure buffers.
• #1061 New command cider-find-ns, bound to C-c C-., which prompts for an ns and jumps to the corresponding source file.
• #1019: New file, cider-debug.el.
  Provides a new command, cider-debug-defun-at-point, bound to C-u C-M-x.
  Interactively debug top-level clojure forms.
• New defcustom, cider-auto-select-test-report-buffer (boolean).
  Controls whether the test report buffer is selected after running a test. Defaults to true.
• Trigger Grimoire doc lookup from doc buffers by pressing g (in Emacs) and G (in browser).
• #903: Isolate
  nrepl-client connection logic from CIDER. New hooks cider-connected-hook
  and cider-disconnected-hook.

• New insert region in REPL command - cider-insert-region-in-repl.
• Pretty printing functionality moved to middleware, adding support for ClojureScript.
  • New command to eval and pprint result: cider-interactive-pprint-eval.
  • cider-format-pprint-eval has been removed.
• Warn when used with incompatible nREPL server.
• Allow the prompt to be tailored by adding cider-repl-prompt-function and cider-repl-default-prompt.
• Support for middleware-annotated completion candidates.

• Better printing of large amounts of exception cause data in the error buffer.
  • New defcustom, cider-stacktrace-print-length (boolean).
• #958: Reuse existing repl
  buffers with dead processes. Users are now informed about existing zombie repl
  buffers and are offered the choice to reuse those for new connections.
• New defcustom, cider-prompt-for-symbol. Controls whether to prompt for
  symbol when interactive commands require one. Defaults to t, which always
  prompts. Currently applies to all documentation and source lookup commands.
• #1032: New functions, cider-find-dwim and
  cider-find-dwim-other-window. These functions combine the functionality of cider-jump-to-var and
  cider-jump-to-resource. Which are now renamed to cider-find-var and cider-find-resource respectively.
• #1014: A prefix of - causes cider-find-var and
  cider-find-resource to show results in other window. Additionally, a double prefix argument C-u C-u

CIDER 0.6.0

CIDER 0.6 is probably the biggest release in the history of the project. It comes with many new features and improvements - most notably proper ClojureScript support via the cider-nrepl middleware. It also brings much improved completion logic and stacktrace display (also via cider-nrepl) + a brand new inspector.

CIDER 0.6 signifies both the maturing of the project and the end of an era. It will be the very last release that will work without the cider-nrepl middleware. Inlining Clojure code is problematic on many levels and I decided that I'm done with it. I'd rather us offload as much logic as we can into middleware. So in CIDER 0.7 cider-nrepl will be a hard dependency, which makes installation a bit more complex, but the extra benefits are well worth a slight inconvenience.

One last thing - support for Emacs 23 was officially dropped and all the source code now uses the lexical scoping introduced in Emacs 24.1. I guess this will affect pretty few users, but it has to be mentioned.

Below are all the gory details. Enjoy!

P.S. I'm having problems uploading the package to Marmalade for the millionth time. Not sure when (if ever) CIDER 0.6 will land there.

New features

• New interactive command cider-change-buffers-designation.
• Cider command uses cider-known-endpoints.

  support for company-mode in cider-complete-at-point.
