enrich-classpath author here. LMK if I can help in any way. since Enrich is disabled by default at the moment, knowing about unforeseen interactions would be incredibly helpful :)

woah... First of all thanks for the blazing fast response! Secondly, I think the issue is actually with CIDER rather than your awesome library 🙂 Here's how my .dir-locals.el looks like

((nil . ((cider-enrich-classpath . nil)
         (cider-preferred-build-tool . lein))))

Let's say you open a directory with those dir-locals. If you M-: (https://www.gnu.org/software/emacs/manual/html_node/emacs/Lisp-Eval.html) and type cider-enrich-classpath , what is the output? If it evaluates to anything other than nil , basically that's the problem: .dir-locals are are not working as configured

Hm... it evaluates to nil yet CIDER invokes lein as follows:

/opt/local/bin/lein update-in :dependencies conj \[nrepl/nrepl\ \"1.0.0\"\] -- update-in :dependencies conj \[cider/piggieback\ \"0.5.2\"\] -- update-in :plugins conj \[cider/cider-nrepl\ \"0.28.7\"\] -- update-in :plugins conj \[mx.cider/enrich-classpath\ \"1.9.0\"\] -- update-in :middleware conj cider.enrich-classpath/middleware -- repl :headless :host localhost

That's pretty weird because cider-enrich-classpath only exists in cider.el, in exactly 3 places: the defcustom declaration and 2 call sites. Those call sites are inside defuns, so they're using whatever value was last set.

Maybe use this pattern:

(advice-add 'the-cider-relevant-function ':around 'my-spy)

It evaluates to t in the advice function yet when I eval in the buffer it's set to nil.

Here's the specific function I added.

(advice-add 'cider-jack-in-cljs :around (lambda (&rest args)
						                  (message (format "%s" cider-enrich-classpath))))

hmm... try printing default-directory also. Perhaps it's bound to something other than your project directory and therefore its dir-locals are disregarded? (kind of a crazy hypothesis but also plausible :) )

Updated advice function

(advice-add 'cider-jack-in-cljs
             :around (lambda (&rest args)
                       (message (format "%s, %s" default-directory
                                                 cider-enrich-classpath))))

Oh I think I know what might be happening. Here's my init.el for CIDER:

(use-package cider
  :commands cider-jack-in
  :config (setq cider-use-tooltips nil
                cider-enrich-classpath t
                cider-lein-parameters "repl :headless :host localhost"))

it does sound very likely :)

That looks to be the culprit so far: a freshly restarted Emacs is telling me cider-enrich-classpath is unbound.

Removing the :commands bit fixed my issue 😄

yup that's the smoking gun happy you got it! Would be curious about your fix later

I would have guessed that the

cider-enrich-classpath t

I think the :commands key in use-package makes the package lazily loaded (though you can force it to load with a supplied command). So the situation must've been something like: 1. Emacs starts up, but cider is neither loaded nor configured. 2. dir-locals sets cider-enrich-classpath to nil. 3. cider-jack-in-cljs forces cider to be loaded and configured. 4. cider-enrich-classpath gets set to t

Yes, that makes sense.

I would love that to be true, but Cursive use has been astonishingly consistent at almost exactly 30% for several years now (according to the community survey).

@bhauman I'm quite embarrassed to say that I hallucinated the wrong name! 😳 No obituary required!

Good to know!!! Wish I hadn’t sent that card!

I will! Incremental learning is fascinating.
