Oof, sorry to hear that. Does this reproduce reliably in one project? In all projects?

@holger311 @kommen have you been able to reproduce it already?

I assume this didn't happen on an open-source project?

@alexyakushev no, but can add you on github if it helps

it’s not exactly light on deps either

All the merrier, recent track-state changes were specifically done for large projects.

It would be easier to find out what's going on if I had the access to the project, but I understand if it is too hard process-wise

@alexyakushev sent you an invite on github

thanks a lot for you help btw!

Np. I break it, I fix it 😄

no luck in reproducing it til yet

we tried: connecting with cider and evaling some namespaces and code (I saw sate messages in the nrepl log). disconnecting/connecting multiple times. connecting two sessions at the same time.

@alexyakushev any idea what else we could have tried?

what would we lose/miss if we remove it from prod?

Very little. I suggested that to @mkvlr in DM.

yes, we will do this and remove the middleware for now in prod. thanks!

If you encounter this ever again, please report back here. I also created an issue: https://github.com/clojure-emacs/cider-nrepl/issues/936

This issue is hopefully fixed in cider-nrepl 0.55.7.

metadata is not typically visible

there is a print-metadata option you could set

bravo!

(doc *print-meta*)
-------------------------
clojure.core/*print-meta*
  If set to logical true, when printing an object, its metadata will also
  be printed in a form that can be read back by the reader.

  Defaults to false.

That's what I expected too 🫤

For the record, I also asked this question in the Standard Clojure Style repo (https://github.com/oakmac/standard-clojure-style-js/issues/194)

I'm not expert on this, but I doubt it is possible. Enforcing such rule would make indentation depend on previous indentation – a mechanism we didn't have anywhere before.
