Example

Here is eglot configuration:

(defvar my/lsp-venv nil
  "Name of virtualenv.
Set it in project's dir-locals file.")

(defclass my/eglot-anakinls (eglot-lsp-server) ()
  :documentation
  "Own eglot server class.")

(cl-defmethod eglot-initialization-options ((_server my/eglot-anakinls))
  "Pass initialization param to anakinls."
  `(:venv ,(when my/lsp-venv
             (expand-file-name
              (concat "~/.virtualenvs/" my/lsp-venv)))))

;; Add this server to eglot programs to handle python-mode and run `anakinls'
(add-to-list 'eglot-server-programs
             '(python-mode my/eglot-anakinls "anakinls"))
