They seem perfectly differentiated to me. One has a / and the other has a - 😜

hey folks, i’m trying to get this project to work with cider: https://github.com/rogerallen/hello_lwjgl

if you clone and do a lein run it works fine, but if you do a M-x cider-jack-in i get this error:

Might be related to this issue: https://github.com/rogerallen/hello_lwjgl/issues/6

at any rate, when I take a look at *Messages*, M-x cider-jack-in seems to be ignoring -XstartOnFirstThread in project.clj

any leads? thanks in advance!

A more general question seems to be - why is M-x cider-jack-in ignoring this: -XstartOnFirstThread

@sashton Yeah, actually I do. Soon cider-nrepl will become orchard-nrepl. This both saves the naming issue and more importantly underlies the fact that cider-nrepl is hardly specific to CIDER. I’d like to see more tool authors involved in all the foundational libraries.

@iwannaseethelight What do you mean by CIDER ignores it? It will happily run whatever you tell it to run as command line arguments.

hey @bozhidar - love the project!

I can stick a bunch of things into jvm-opts in project.clj and they show up in *Messages* when booting up the repl via cider-jack-in, but if you specify the -XstartOnFirstThread option it does not show up in *Messages* - I guess that doesn’t necessarily mean it’s not getting picked up, but trying to start that lwjgl project fails and says to specify the same option

just not sure why

in that project btw, they have a different approach where they boot up an nrepl server in their game itself and then cider-connect to it

I see. In general CIDER is not involved at all in starting the REPL - it just lein/boot/whatever you choose to invoke, that’s why I meant CIDER can’t really ignore anything of this type.

I’m trying to do cider-jack-in (with and wihout a project) and it fails to start with error in process sentinel: Could not start nREPL server: Exception in thread "main" java.io.FileNotFoundException: Could not locate cider/nrepl/middleware/util/misc__init.class or cider/nrepl/middleware/util/misc.clj on classpath., compiling:(refactor_nrepl/middleware.clj:1:1)

For both lein based projects, and clj outside of a project. This is with the latest stable CIDER>

I gather that refactor-nrepl has issues, so I would be glad to just turn that off if that fixes the problem but I cannot find out how!

Ok I found http://cider.readthedocs.io/en/latest/troubleshooting/#commonly-encountered-problems-and-how-to-solve-them - trying that

hmm. turning off “Cider Inject Dependencies At Jack In” does not seem to help

Starting nREPL server via clojure -e '(require (quote cider-nrepl.main)) (cider-nrepl.main/init ["refactor-nrepl.middleware/wrap-refactor", "com.billpiel.sayid.nrepl-middleware/wrap-sayid", "cider.nrepl/cider-middleware"])'...

Please check that namespaces with dashes use underscores in the Clojure file name.

so it starts up differently but still errors

previously it was

@joost-diepenmaat You need to disable the injection of the refactor-nrepl (as mentioned in the troubleshooting page).

Ah I see

You’re using some version of clj-refactor.el that’s not compatible with CIDER. I think the only version that work OK is their current master.

If turned off the wrong knob

(setq cljr-inject-dependencies-at-jack-in nil)

should use cljr-inject-dependencies-at-jack-in instead of cider-inject-dependencies-at-jack-in

Yes.

You definitely want CIDER to inject its own deps.

yeah doing that fixed the problem

thanks a lot

You’re welcome!

when I call cider-eval-buffer after jacking in to a cljs repl I get the message user-error: ‘cider-eval-buffer’ needs a ClojureScript REPL. \n If you don’t know what that means, you probably need to jack-in (‘, "’).

i have the repl buffer open.. and it seems to work

total emacs+cider noob here so I could be doing something wrong

if i jack-in again, it warns me that a repl buffer already exists

i think the repl that opened is a clojure repl not a cljs repl..

are you trying to work with clojurescript or clojure?

cljs

I'm following the docs at https://cider.readthedocs.io/en/latest/clojurescript/

Ok.. new data, found this error in one of the repl buffers: ClassNotFoundException cemerick.piggieback java.net.URLClassLoader.findClass (URLClassLoader.java:381)

But I do have piggieback in my deps list

😕 the cider/emacs vids made this look much easier heh

i obviously have something screwed up

hehe

@ramblurr Make sure you’re using cider/piggieback not the older cemerick/piggieback.

(in your project dependencies I mean)

Hmm, actually I see in your error you’re using an older version of CIDER that requires that older package.

Aren’t you on CIDER 0.17?

Hi all, quick debugger question…. The debugger works great on libraries that I’m pulling in as dependencies. I call cider-debug-defun-at-point and it works beautifully. However, how do I now turn debugging off on that function?? If I’m debugging an expression in my own project I just evaluate it to turn off the debugger. But not sure how to do that on an external namespace…. Hope that makes sense! Any help would be greatly appreciated.

@bozhidar confirmed i am using cider/piggieback and I'm using spacemacs.. need to check the cider version it uses

@fedreg calling cider-eval-defun-at-point will re-compile that function without the debugger

(though cider-eval-buffer should still work even in read-only mode?)

@tanzoniteblack Thx! Neither of those work for me…. If it works for you tho it must be something in my local setup. I can dig deeper. Wasn’t sure if there was some other func that I was not seeing

let me double check, I told you that working off memory

yep, that's working for me running CIDER 0.17.0 (Andalucía) with cider loading the cider-nrepl into lein for me (i.e. I'm not manually specifying the additional libraries anywhere)

Alright, I’ll debug locally. At least now I know that I should be able to turn off the debugger on read-only file. Appreciate the help!
