;;; Commentary:

;; .dir-locals.el for use with the Emacs Eglot LSP client and
;; python-lsp-server (pylsp) LSP server v1.10.0.

;; Default values in accordance with
;; https://github.com/python-lsp/python-lsp-server/blob/v1.10.0/CONFIGURATION.md
;; (or commit 2a5a953).  A value of null means we do not set a value and
;; therefore use the plugin's default value.

;; The recommended format for the `eglot-workspace-configuration' variable
;; value is a property list (plist for short):
;;
;; (:server plist…)
;;
;; Here :server identifies a particular language server and plist is the
;; corresponding keyword-value property list of one or more parameter
;; settings for that server, serialized by Eglot as a JSON object.
;; plist may be arbitrarily complex, generally containing other
;; keyword-value property sublists corresponding to JSON subobjects.

;; The JSON values are represented by Emacs Lisp values as follows:

;; JSON                         | Emacs Lisp
;; ------------------------------------------------
;; :true i.e. true              | t
;; :false i.e. false            | :json-false
;; :null i.e. null              | nil
;; :[] i.e. [] the empty array  | []*
;; :{} i.e. {} the empty object | eglot-{}**

;; * Lisp array elements should not be comma separated as they are in a
;; JSON array.
;; ** Must be evaluated via a backquote or `list'
;; e.g. `(:pylsp (:plugins (:jedi (:env_vars ,eglot-{})))) or
;;       (list :pylsp (list :plugins (list :jedi (list :env_vars eglot-{}))))

;;; How to Use:

;; 1. Place this file in your project directory.
;; 2. Adjust settings as desired.  Inline comments below indicate the
;; expected type, possible values if appropriate and default pylsp value
;; for each configuration setting.

Yes, it seems to be working for you!

My Eglot events buffer does not mention anything about rope, let alone autoimport. I’m not sure why, as I’m sure the package and plugins are installed.

Copying over my whole events buffer might be oo much, but is there anything else I could do to find out what the issue is with my setup?

OK, so I'm still on Emacs 27.1 so am not using python-ts-mode. Maybe, that is the reason we are seeing different behaviours? What is your python and eglot configurations?
