Compatibility with clojure-lsp?

[dijonkitchen]

Is the functionality in CIDER compatible with https://github.com/snoe/clojure-lsp ? I figure that would allow all of the CIDER goodies to work across platforms/editors if it was under LSP.

Compatible in what sense? You can run an LSP server alongside nREPL if that's what you're asking for, but you'll have to be careful with cider-mode and lsp-mode interfering with one another.

I figure that would allow all of the CIDER goodies to work across platforms/editors if it was under LSP.

CIDER's backend is already portable, as nREPL is an open protocol and everything's just nREPL middleware. We can certainly implement LSP in terms of nREPL and provide a runtime-powered alternative to clojure-lsp, but that's not a priority for me and someone will have to tackle it if they want to see it happen.

I use lsp alongside of CIDER. They work fine together but i have the following config. It mainly makes CIDER in charge of indentation and completion.

(use-package lsp-mode
  :init
  (setq lsp-clojure-server-command '("bash" "-c" "cd ~/projects/clojure/clojure-lsp && lein run"))
  (setq lsp-enable-indentation nil)
  (setq lsp-enable-completion-at-point nil)
  ;; (setq indent-region-function #'clojure-indent-function)
  (add-hook 'clojure-mode-hook #'lsp)
  (add-hook 'clojurec-mode-hook #'lsp)
  (add-hook 'clojurescript-mode-hook #'lsp)
  :config
  (require 'lsp-clojure)
  (add-to-list 'lsp-language-id-configuration '(clojure-mode . "clojure"))
  (add-to-list 'lsp-language-id-configuration '(clojurec-mode . "clojure"))
  (add-to-list 'lsp-language-id-configuration '(clojurescript-mode . "clojurescript")))

@dpsutton Alternatively you can disable the LSP indentation/completion when cider-mode kicks in and enable them when it's turned off.

@bbatsov oh i like that! i'm gonna switch it over

@dpsutton did you manage to make them play well together?

I'm trying to use LSP + Cider and one problem I see is that Cider redefines the key mappings for things like <M-.> and <C-.>. I'd prefer to be able to tell Cider not to be xref and imenu provider because I prefer LSP for that.
Right now the only way to achieve this is to re-set these bindings to what I want after cider-mode is enabled or maybe sth. else.
