great visual guide, but regardless what I set in my init file, the values are always reset to their default values (setting them after loading lsp-mode works fine). I spefically have the following two lines in init.el

(setq lsp-ui-sideline-show-code-actions t)
(setq lsp-ui-sideline-show-diagnostics nil)

but to no avail
Is there something obvious I am missing here?

[ericdallo]

Do you use any emacs framework that may override those settings?

[uliw]

upon some digging, it appears that this is related to some other package in my startup file. I'll report back

[uliw]

after removing everything, and then adding it back, it now works as expected. I was not able to pin down any specific cause.

Thanks for this guide, but I haven't been able to disable the lsp-ui-doc feature -- which is driving me nuts (I don't want to be told what a u8 is ever 2s)

This is what I have in my init.el -- I've tried a whole range of solutions but about to abandon this all. But if you have any ideas that would be great.

(with-eval-after-load "lsp-ui-doc"
  (setq lsp-ui-doc-enable nil)
  (setq lsp-ui-doc-show-with-cursor nil))

I have also checked that all the variables are actually set to nil. I am using emacs 27.2

Many thanks

Can you show me a screenshot of what you want to disable?

[shaze]

Thanks for the prompt reply

See: http://dept.ee.wits.ac.za/~scott/emacs-screenshot.png

See the minibuffer with the long explanation for what a bool is. This happens when the cursor is moved over bool (or any other keyword, type, variable etc). In this case it is a remote machine I am ssh-ing into -- so no X, GUI or mouse involved. However, I get the same behaviour on my Mac (Emacs 28.2) or if I use X.

[yyoncho]

@shaze, as you can see in bottom-right, you have started eglot as well and it is showing this message.

[shaze]

Thank you! The danger of putting thing in an init.el file that you don't understand.

(setq lsp-modeline-diagnostics-enable nil)

Is it possible to make this show errors only?

[yyoncho]

@larrasket ATM there is no option for that with a setting. You can do it like this:

(with-eval-after-load 'lsp-modeline
  (defun lsp-modeline-diagnostics-statistics ()
    "Calculate diagnostics statistics based on `lsp-modeline-diagnostics-scope'."
    (let ((diagnostics (cond
                        ((equal :file lsp-modeline-diagnostics-scope)
                         (list (lsp--get-buffer-diagnostics)))
                        (t (->> (eq :workspace lsp-modeline-diagnostics-scope)
                                (lsp-diagnostics)
                                (ht-values)))))
          (stats (make-vector lsp/diagnostic-severity-max 0))
          strs
          (i 0))
      (mapc (lambda (buf-diags)
              (mapc (-lambda ((&Diagnostic? :severity?))
                      (when severity?
                        (cl-incf (aref stats severity?))))
                    buf-diags))
            diagnostics)
      (while (< i lsp/diagnostic-severity-max)
        (when (and (= i lsp/diagnostic-severity-error)
                   (> (aref stats i) 0))
          (setq strs
                (nconc strs
                       `(,(propertize
                           (format "%s" (aref stats i))
                           'face
                           (cond
                            ((= i lsp/diagnostic-severity-error) 'error)
                            ((= i lsp/diagnostic-severity-warning) 'warning)
                            ((= i lsp/diagnostic-severity-information) 'success)
                            ((= i lsp/diagnostic-severity-hint) 'success)))))))
        (cl-incf i))
      (-> (s-join "/" strs)
          (propertize 'mouse-face 'mode-line-highlight
                      'help-echo "mouse-1: Show diagnostics"
                      'local-map (when (require 'lsp-treemacs nil t)
                                   (make-mode-line-mouse-map
