Frequently Asked Questions
CIDER officially supports Emacs 25.1+, Java 8+ and Clojure(Script) 1.8+.
|CIDER 0.17 was the final release which supported Java 7 and Clojure(Script) 1.7.|
nrepl.el was renamed to CIDER in version 0.3 to avoid confusion with the nREPL
server itself and to better reflect the fact that CIDER is way more than an
nREPL client for Emacs. Additionally, the new name presents us with the
opportunity to support alternative evaluation backends (e.g. the socket REPL
introduced in Clojure 1.8) down the road.
monroe is basically a fork of an old CIDER version before the time we started relying on nREPL middleware.
There’s pretty much no relationship. inf-clojure provides a REPL based on the
comint Emacs package - you’re basically running an external REPL process
inside of Emacs (there’s no network connectivity involved). The advantage of
this is that you have no external dependencies what-so-ever - you just need some
command to start a REPL process for you.
Cursive is pretty awesome! Depending on your programming preferences (using an IDE vs building a custom editing experience tailored to your needs) it might be a better option for you than CIDER.
The codenames are usually some of the favourite places of CIDER’s head maintainer (Bozhidar).
|Bozhidar really loves Spain and the West Coast of the US, so he tends to name really special releases with codenames related to them (e.g. Seattle, California, Andalucia, etc).|
There’s nothing particularly complex in CIDER itself, but getting to grips with Emacs might be a bit challenging for some people.
Generally you can simplify the initial learning experience a lot by using some Emacs "starter kit" and picking up a good book on Emacs (e.g. Mastering Emacs).
Prelude is maintained by the primary CIDER author himself, while
Spacemacs is an excellent option for vim refugees (as it places a heavy emphasis
on vim emulation via
No. Stable releases are issued when the maintainers feel a new release is warranted. The maintainers generally aim to deliver at least 2-3 stable releases per year.
There’s no exact roadmap for the 1.0 release. Roughly speaking the idea is to release 1.0 once our ClojureScript support is as good as the Clojure support and when the most important refactoring functionality from our sibling project clj-refactor lands into CIDER.
|While there’s no exact roadmap for the 1.0 release, we do have a roadmap.|
Yep. We want to give people a reason to talk about CIDER at such events. :-)
|Inviting Bozhidar or any other core CIDER developers to present at Clojure conferences is likely going to results in more CIDER releases, so you should totally do this!|
It’s pretty stable. Serious regression are introduced rather rarely and are usually fixed within a few hours. Using the MELPA build gives you early access to new features and you’re also helping the maintainers with the testing process.
Yes, you can. You just need to remove the
cider package, pin
cider to MELPA Stable
and reinstall it. Basically you need to do the following:
M-x package-remove cider
(add-to-list 'package-pinned-packages '(cider . "melpa-stable") t)to your Emacs config
Restart Emacs (or reload your config)
M-x package-install cider
No, you can’t. Unfortunately
package.el doesn’t support the concept of historical versions of a package -
there’s always only one version that’s available - the latest one.
Hopefully yes. Adding support for the socket REPL is definitely on our radar, but unfortunately it will require both significant changes to CIDER and the development of some alternative to essential nREPL functionality (like multiple evaluation sessions) for the socket REPL.
|There’s more information about the work that needs to be done in our roadmap document.|
Same answer as above. One thing is certain - prepl is much more convenient for the purposes of CIDER than the plain socket REPL.
That’s extremely unlikely. Even if we eventually add support for the new socket REPL, we’ll continue supporting nREPL as well.
Recently nREPL was migrated out of
Not at all. The functionality in
cider-nrepl is pretty editor-agnostic and is
utilized by various editor plugins. Some prominent examples would be
vim-fireplace and Visual Studio Code’s
