CIDER nREPL does not work in Emacs 29.1

[aurbital]

Expected behavior

M-x cider-jack-in launches repl

Actual behavior

The first time running M-x cider-jack-in produces the error Package cl is deprecated and no repl launches. Subsequent attempts to run M-x cider-jack-in produces the error Eager macro-expansion failure: (wrong-number-of-arguments (3 . 4) 2)

Attempts to start a leiningen repl using lein repl and then running M-x cider-connect produces the same set of responses from emacs as above.

Please note: this is my first time attempting to run a CIDER nREPL. I've never successfully gotten a CIDER nREPL to run on my machine.

Steps to reproduce the problem

My init.el was downloaded from here: , which pulls cider from melpa-stable. This file was downloaded yesterday 2023 Sept 9

Environment & Version information

Emacs: 29.1-1 Leiningen: 2.10.0 Java 20.0.2 OpenJDK 64-Bit Server VM CIDER: ? whatever was downloaded from melpa-stable as of 2023 Sept 9 OS: macOS Ventura 13.4.1

Hi! Thanks for the report.

Eager macro-expansion failure:

Sometimes these go away by removing .elc files before starting Emacs.

You can try:

cd ~/.emacs.d; find . -type f -name "*.elc" -exec rm {} +

My init.el was downloaded from here

Looks like you intented to include a link which is missing.

Please note: this is my first time attempting to run a CIDER nREPL. I've never successfully gotten a CIDER nREPL to run on my machine.

Given this, could you please try Emacs 28, just to discard some possibilities?

I'd recommend https://emacsformacosx.com/ because it's a very vanilla build. You can run the underlying .app file without replacing your installed Emacs.

Oops the link didn't paste properly, it's this: https://github.com/flyingmachine/emacs-for-clojure/

I just tried using Emacs 28 on a different Mac computer (different OS), same problem, I get the error Package cl is deprecated and no nREPL starts. A second attempt gives the error Wrong number of arguments: (3 . 4), 2

Emacs: 28.2 Leiningen 2.9.8 Java 18.0.1.1 OpenJDK OS: macOS Catalina 10.15.7

So Emacs 28 doesn't work either

And yes both Emacs 28 and Emacs 29 that I'm using are the vanilla https://emacsformacosx.com/ version

Thanks!

https://github.com/flyingmachine/emacs-for-clojure/ suggests downloading a .zip file which contains an elpa directory. This is both highly unidiomatic, and problematic.

~/.emacs.d/elpa should always be created and populated by your package manager. I'd also recommend deleting it when switching Emacs versions.

So, please check if it's possible to:

• quit emacs, delete ~/.emacs.d/elpa, start again, see the packages being downloaded
• use https://github.com/flyingmachine/emacs-for-clojure/ in an alternative way
• use some other emacs setup.

I'll close this issue as it's not CIDER-related, however I'll be happy to help within my capacity.

deleting ~/.emacs.d/elpa did the trick! Thank you! M-x cider-jack-in works now!

Cheers - enjoy!
