Re: Question Regarding Line Number Mode For Working With LSP Mode

["Samuel Banya" <sbanya@fastmail.com>]

Hey Eli,

I tried to do this, but unfortunately using ':hook' for LSP mode within my config doesn't work for some reason, check the ':hook' section below (https://github.com/SamuelBanya/SamsEmacs/blob/main/configuration.org)

#+begin_src emacs-lisp
  (defun ef/lsp-mode-setup ()
    ;; Taken from this 'System Crafters' video:
    ;; https://www.youtube.com/watch?v=E-NAM9U5JYE
    ;; This allows breadcrumb segments to appear in projects
    (setq lsp-headerline-breadcrumb-segments '(path-up-to-project file symbols))
    (lsp-headerline-breadcrumb-mode))

  (use-package lsp-mode
    :ensure t
    :commands (lsp lsp-deferred)
    ;; Taken from this page:
    ;; https://www.mattduck.com/lsp-python-getting-started.html
    :init
    (setq lsp-keymap-prefix "C-c l")
    (add-hook 'c-mode-hook 'lsp)
    (add-hook 'c++-mode-hook 'lsp)
    (add-hook 'python-mode-hook 'lsp)
    (add-hook 'ruby-mode-hook 'lsp)
    (add-hook 'js2-mode-hook 'lsp)
    (add-hook 'typescript-mode-hook 'lsp)
    (add-hook 'web-mode-hook 'lsp)
    (add-hook 'csharp-mode-hook 'lsp)
    (add-hook 'vue-mode-hook 'lsp)
    (add-hook 'yaml-mode-hook 'lsp)
    :hook
    (display-line-numbers-mode)
    :config
    (lsp-enable-which-key-integration t)
    ;; Set 'lsp-idle-delay' to 0.5 seconds for quick autocompletion
    (setq lsp-idle-delay 0.5)
    ;; Adding this to force lsp to auto-guess the root directory of the project:
    (setq lsp-auto-guess-root t))
#+end_src
