Works with Rust, but not Python File mode specification error: (void-function elgot-ensure)

[azzamsa]

I have the config below:

(use-package eglot
  :config
  (add-to-list 'eglot-server-programs '(rust-mode . ("rust-analyzer")))
  (add-to-list 'eglot-server-programs '(python-mode . ("pyls"))))

(use-package rust-mode
  :config
  (add-hook 'rust-mode-hook (lambda ()
			      (eglot-ensure))))

(use-package python
  :straight (:type built-in)
  :config
  (add-hook 'python-mode-hook (lambda ()
				(elgot-ensure))))

Elgot works when I open a Rust file, but when I open a Python file. I got File mode specification error: (void-function elgot-ensure)
I tried to invoke M-x elgot but no-candidate in minibuffer. Even I have visited the elgot.el and run eval-buffer, I still can't invoke Elgot interactively.

I try to debug the problem, using the code below:

;; set user-emacs-directory to the directory where this file lives
;; do not read or write anything in $HOME/.emacs.d
(setq user-init-file (or load-file-name (buffer-file-name)))
(setq user-emacs-directory (file-name-directory user-init-file))

;; set custom-file to write into a separate place
(setq custom-file (concat user-emacs-directory ".custom.el"))
(when (file-readable-p custom-file) (load custom-file))

;; configure melpa (and other repos if needed)
(require 'package)
(add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/") t)
(setq package-enable-at-startup nil)
(package-initialize)
(when (not package-archive-contents)
    (package-refresh-contents))

;; bootstrap `use-package'
(setq package-pinned-packages
      '((bind-key           . "melpa")
        (diminish           . "melpa")
        (use-package        . "melpa")))

(dolist (p (mapcar 'car package-pinned-packages))
  (unless (package-installed-p p)
    (package-install p)))

;; install and configure packages
(use-package eglot
  :config
  (add-to-list 'eglot-server-programs '(python-mode . ("pyls"))))

(use-package python
  :config
  (add-hook 'python-mode-hook (lambda ()
				(elgot-ensure))))

However, I got:

❯ emacs -q -l init.el --batch
Loading /home/azzamsa/playground/elgot-tmp/.custom.el (source)...
Error (use-package): Cannot load eglot

I tried to run remove the install and configure packages section, and opted to install it manually using M-x package-install. However, there is no candidate. Even I have run the package refresh.

In the first case: Elgot is installed via straight.el: it works with Rust but not Python.
in the second case: I try to debug the problem using plain use-package, but no package candidate.

Help is very appreciated.
Thanks for Elgot.

elgot -> eglot ?

Also lambda is not necessary.

(add-hook 'python-mode-hook 'eglot-ensure)

Oh, I need to take a rest.

Thanks a ton.
