Disable Hover on Diagnostics and Enable Sideline Instead of Echoing

[gchape]

I don't think this is directly related to eglot, because eglot uses ElDoc and FlyMake. However, due to my lack of expertise, I was unable to find the solution in the documentation.

In short, I want to disable hovering for diagnostics and enable sideline diagnostics instead of echoing them in mini-buffer (Personally, I prefer to see the error and the code on the same line).

My current configuration:

(use-package eglot
  :hook ((emacs-lisp-mode js2-mode typescript-mode html-mode css-mode json-mode) . eglot-ensure)
  :custom
  (eglot-autoshutdown t)
  (eglot-extend-to-xref nil)
  (eglot-events-buffer-size 0)
  (eglot-ignored-server-capabilities
   '(:hoverProvider
     :documentHighlightProvider
     :documentFormattingProvider
     :documentRangeFormattingProvider
     :documentOnTypeFormattingProvider
     :workspace/didChangeWorkspaceFolders
     :colorProvider
     :foldingRangeProvider))
  (eglot-stay-out-of '(yasnippet)))

(use-package flymake
  :config
  (define-key flymake-mode-map (kbd "M-n") 'flymake-goto-next-error)
  (define-key flymake-mode-map (kbd "M-p") 'flymake-goto-prev-error))

Is it feasible to achieve this on par with eglot's settings?

1. Tooltips can be disabled globally by using: (tooltip-mode nil).
2. Highlighting on hover can be disabled by setting: setq (mouse-highlight nil).

The second one is not optimal because highlighting is quite useful, so it would be better to disable it locally under Flymake. If I disable ElDoc, the diagnostics are not shown in the mini-buffer at point, but hover still displays diagnostics in echo area.

Flycheck has such a nice option: flycheck-help-echo-function. The tooltips and echoing are gone.

I hope it is also possible in Flymake. I want to migrate from lsp-mode...

Read https://joaotavora.github.io/eglot/#More-Customization-1 about how to tweak Eldoc in Elglot to remove certain bits from it. This is a purely Eldoc customization that you may also want outisde of Eglot. Then read about flymake-show-diagnostics-at-end-of-line. I don't know anything about sideline mode, sorry.

The documentation function you're probably trying to remove is flymake-eldoc-function
