Python Development Environment

Inside the init.el, uncomment

(python +lsp)
lsp

Install the language servers, i use pipenv, but pip will work

pipenv install python-lsp-server

sudo pacman -S npm

npm install pyright pyright-langserver

Inside the config.el

;; REMEMBER TO CHANGE THE PATH TO YOUR NODE-MODULES .bin DIRECTORY
(after! tramp
  (setq tramp-remote-path (append tramp-remote-path '("/home/jonny/node_modules/.bin/"))))

(with-eval-after-load 'tramp
  (add-to-list 'tramp-remote-path 'tramp-own-remote-path))

;;(after! eglot
  ;; Ensure `pyright` is used for Python files
;;  (add-to-list 'eglot-server-programs '(python-mode . ("pyright-langserver" "--stdio"))))
(use-package! company
  :after eglot
  :config
  ;; This configures company to use company-capf, which is the completion-at-point-function backend
  (setq company-idle-delay 0.5) ; Adjust the delay according to preference
 ;; company-capf is a generic completion mechanism that works with eglot.
  (setq company-backends '(company-capf)))

;; Ensure `eglot` is installed and configured for Python
(use-package! eglot
  :hook (python-mode . eglot-ensure)
  :config
  (add-to-list 'eglot-server-programs '(python-mode . ("pyright-langserver" "--stdio")))
  (add-hook 'eglot-managed-mode-hook (lambda () (company-mode 1))))

(setq org-agenda-files (directory-files-recursively "~/org-agenda" "\\.org$"))
(require 'pyvenv)
(add-hook 'python-mode-hook #'pyvenv-mode)

(defun open-eshell-in-bottom-window ()
  "Split the window and open eshell in the bottom window with a specific size."
  (interactive)
  ;; Calculate the desired window height for the eshell window: e.g., 1/3 of the frame height.
  (let ((window-size (- (floor (* 0.33 (frame-height))) window-min-height)))
    ;; Split the window with the specified height and open eshell in the new window.
    (split-window-below (- window-size))
    (other-window 1)
    (eshell)))

(global-set-key (kbd "C-c e") 'open-eshell-in-bottom-window)

Inside the packages.el

(package! pyvenv)
(package! eglot)

Inside alt-x

- open-eshell-in-bottom-window C-c e
- doom/reload
- eshell
- eglot
- pyvenv-activate (although, my config should automatically load this if in a package directory with a virtual environment)
