@ryanwatkins54 I needed to set cider-jdk-src-paths for it to work

bozhidar08:03:22

As long as some Java sources are on your classpath the code lookup should work.

I have gotten Drawbridge integrated into my app 🎉 ... and now I am wondering whether it's possible to get CIDER to connect to that.

holtzermann1713:03:47

Looks like the relevant issue in the issue tracker is this one: https://github.com/clojure-emacs/cider/issues/39 currently closed as of 2014, last updated in 2017, so I guess the answer is "not without some work."

holtzermann1713:03:36

The last comment in the thread there talks about something called Lein Catapult https://github.com/malyn/lein-catapult which seems like in principle it could be used

holtzermann1713:03:20

It has one commit from six years ago, but hey, it's worth a try!

holtzermann1714:03:13

Didn't work out of the box, but maybe it won't be too hard to debug. https://github.com/malyn/lein-catapult/issues/2

holtzermann1714:03:12

However, that bug doesn't seem to matter, since if I rerun lein catapult :[email protected]:8080/repl I get a message that I am connected to Drawbridge!

holtzermann1714:03:53

I've created a fork with modern dependencies [com.github.holtzermann17/lein-catapult "4fa2f909f334d2094b2885567f0f036da3518820"] via Jitpack, but I don't think this matters at the moment.

holtzermann1714:03:32

OK, but now, trying to connect with CIDER I get the following print out:

holtzermann1714:03:56

CIDER still shows the loading symbols [=== ] [====] [ ===] [ ==] etc., and I don't get a prompt. However the cider-repl buffer does say this at the top:

;; Connected to nREPL server - 
;; CIDER 0.24.0 (package: 20200215.223) (India), nREPL 0.6.0

holtzermann1715:03:13

I updated CIDER issue https://github.com/clojure-emacs/cider/issues/39 with this information. It looks like it is pretty close to working...

holtzermann1715:03:56

Ah, here's an error message printed out by my app:

holtzermann1715:03:14

Exception in thread "nRepl-session-ba6f45c9-8bc1-4e9b-8bf6-85c51fa10aec" java.lang.ClassCastException: class java.lang.String cannot be cast to class java.lang.Character (java.lang.String and java.lang.Character are in module java.base of loader 'bootstrap')

holtzermann1716:03:47

Woah, I also see that despite being very slow more things are happening on the lein catapult repl if I leave if for a while.

robert-stuttaford16:03:43

is there a way to have the *cider-result* buffer print newlines instead of the literal \n , inside an EDN output?

ag21:03:51

Somehow for some reason eldoc tips not showing up for me anymore. cider-eldoc-display-for-symbol-at-point and cider-eldoc-display-context-dependent-info are set to t. I have global-eldoc-mode enabled, but whenever I try to run M-x eldoc-mode it says: “There is no ElDoc support in this buffer”. Can someone help me to investigate why it’s not working?

dpsutton22:03:59

Are you running a custom built emacs? 27 or 28?

ag22:03:19

Ah… this is what I’m seeing: CIDER sets eldoc-documentation-function but eldoc-documentation-functions is nil, that prevents eldoc from enabling the mode in the buffer

ag22:03:41

@dpsutton yes I’m running 28, because I want jansson support

dpsutton22:03:06

Well it sounds like you’re on your way. I think I heard this api changed in 28

ag22:03:24

> Well it sounds like you’re on your way Not really. I’m still not sure how to fix this

ag22:03:36

Nevermind. Fixed it by doing (add-hook 'eldoc-documentation-functions #'cider-doc nil t)
