Built-in Modes

hook default settings to configured language modes

  (let ((langs '("sh" "c++" "mhtml" "java" "js" "python" "latex")))
    (dolist (lang langs)
      (add-hook (intern (concat lang "-mode-hook")) (lambda () (lang-default-settings)))))

add LSP server program names to eglot's configuration

  (let ((server-programs '((c++-mode . ("clangd"))
                           (mhtml-mode . ("html-language-server"))
                           (java-mode . ("jdtls"))
                           (js-mode . ("typescript-language-server"))
                           (python-mode . ("pyright"))
                           (latex-mode . ("texlab")))))
    (setq eglot-server-programs (append server-programs eglot-server-programs)))
