Hi Bozhidar

Thanks for the awesome work however when I upgraded to version 0.9 I get the following error when starting cider in emacs:

Starting nREPL server via lein repl :headless...
nREPL server started on 55266
nREPL: Establishing direct connection to localhost:55266 ...
nREPL: Direct connection established
error in process filter: cider-repl-mode: Symbol's function definition is void: clojure-mode-variables
error in process filter: Symbol's function definition is void: clojure-mode-variables

Will you please help me out here?

Best regards

Shahrdad

Don't bother please, after I upgraded the clojure-mode issue got fixed.

Again thanks for your magnificent tool.

Best regards

Wow!! Many thanks to all CIDER contributors.

I didn't get it to work at first, but deleting all previous *.elc files and restarting emacs solves the problem.

Congratulations!

Yours,

Avicenna

[Bozhidar Batsov]

Yeah, that's an unfortunate problem with package.el. See https://github.com/clojure-emacs/cider/issues/1050#issuecomment-112595451

I upgraded to version 0.9 I get the following error when starting cider in emacs:

Welcome to the wonderful world of emacs, where when you upgrade a module you have to hunt down all of the dependencies manually to upgrade them all separately *and* lift the hood to perform additional arcane rituals in place of simply download, install, run or even download, configure, make, make install, run. We hope you enjoy your stay. And that you are, or know, a good mechanic. :)

(OK, OK, it is aimed at an audience of mainly computer programmers, so it can be forgiven I guess for assuming every user is one, but even so, I prefer my tools to download, install, and then get out of the way and let me program *my* project rather than needing me to program parts of *them* first...)

I think I managed to get almost everything to work.

The only thing that doesn't work is the nrepl history. When I hit M-p or M-n, I get

Symbol's function definition is void: assert

When I run (require 'cl) it changes to Invalid function: assert

Am I the only one with this problem? Because I found no reports of it.

[Leon Grapenthin]

Nevermind, I found the solution. (require 'cl) manually before compiling cider.

I must say, though, that every time something is upgraded it *is* quite amusing watching you emacs users running around chasing your tails for several hours afterwards while the rest of us are already getting useful work done. :)

[maverickavi]

Yeah, that's one of emacs's powers: provide amusement for people. I am happy that you are entertained :)

Go do something useful with your IDE (or whatever) for a change and stop trolling on this thread...

[Bozhidar Batsov]

Ouch. That's an oversight on my part. Seems we've used a few functions straight from `cl` instead of the newer `cl-lib`. Thought I had all those usages fixed, but I guess I haven't. 

[Bozhidar Batsov]

nREPL 0.2.6 is pretty old and has some serious bugs in it (alas there hasn't been a lein release for a while). You'll have to pull in a newer nREPL manually to get rid of this.

{:user {:dependencies [[org.clojure/tools.nrepl "0.2.10”]]}}

Unfortunately this doesn't necessarily work - it certainly doesn't
work for me! - as per the following:

[Bozhidar Batsov]

Yeah, I'm aware of those problems, but as you already know they have to fixed in leiningen. At least these days leiningen has an alternative (https://github.com/boot-clj/boot).

Good point - this is an opportunity for me to try out boot. :-)

Dear CIDER Devs,

thanks for the time and effort you've put into this!  Works fine for me.  Update issues were totally minor so far.  Fixing them probably took less time than Eclipse needs to download the update information, let alone calculating dependencies. :-P


Cheers,
stefan

[Bozhidar Batsov]

Happy to hear this! :-)

[Baishampayan Ghose]

By the way, I just tried connecting to two different repls from the
same project (the regular one + one started by fighweel) and it made
my Emacs hang :-\

Connecting to multiple repls on different projects works fine.

Thanks,
BG

Submit a ticket + some repro steps and we'll have a look at it.

[Ed Maphis]

On that note,  the nrepl 0.2.6 problem is a pretty old issue by now. Does anyone know if there are any plans to update leiningen.

[Leon Grapenthin]

Yeah, it usually happens when you start the second REPL while having the REPL buffer open. It doesn't happen if you open the second REPL e. g. on the project.clj...

[Leon Grapenthin]

Oh and you can also C-g and kill the unusubal REPL buffer if this happens.

[Bozhidar Batsov]

You should definitely collect all this information in a bug report and we'll track this issue down.
