Standalone run

This code snippet runs app launcher without emacs frame To use it, create a global keyboard shortcut with the following code emacsclient -cF "((visibility . nil))" -e "(emacs-run-app-launcher)"

  (defun emacs-run-app-launcher()
    (emacs-run-launcher 'app-launcher-run-app))

Backup files (tilda files)

By default, Emacs creates automatic backups of files in their original directories, such “file.el” and the backup “file.el~”. This leads to a lot of clutter, so let’s tell Emacs to put all backups that it creates in the .emacs.d directory.

(setq backup-directory-alist '((".*" . "~/.emacs.d/tildafiles")))

Sane defaults

(electric-pair-mode 1)       ;; Turns on automatic parens pairing

Minibuffer escape

By default, Emacs requires you to hit ESC three times to escape quit the minibuffer.

Modeline

The modeline is the bottom status bar that appears in Emacs windows. While you can create your own custom modeline, why go to the trouble when Doom Emacs already has a nice modeline package available. For more information on what is available to configure in the Doom modeline, check out: Doom Modeline

(use-package doom-modeline

	doom-modeline-time t         ;; shows time
        doom-modeline-persp-icon nil)) ;; adds folder icon next to persp name

Mini-echo modeline

The "global modeline" package, that disables pro buffer modeline and shows itself in echo area.

          :init (mini-echo-mode)

Pixel-scrolling

Native

This doesn-t work for me for now, very laggy and inconsistent

;;; Scrolling.
;; Good speed and allow scrolling through large images (pixel-scroll).
;; Note: Scroll lags when point must be moved but increasing the number
;;       of lines that point moves in pixel-scroll.el ruins large image
;;       scrolling. So unfortunately I think we'll just have to live with
;;       this.

(setq pixel-dead-time 0) ; Never go back to the old scrolling behaviour.

PDF Tools

pdf-tools is a replacement of DocView for viewing PDF files inside Emacs. It uses the poppler library, which also means that ‘pdf-tools’ can by used to modify PDFs. I use to disable ‘display-line-numbers-mode’ in ‘pdf-view-mode’ because line numbers crash it.

   (unless (kylekrein/is-android) ;; fails to compile

SHELLS AND TERMINALS

Eshell

Eshell is an Emacs 'shell' that is written in Elisp.

  (use-package eshell-syntax-highlighting
    :ensure t
    :after esh-mode
    :config
    (eshell-syntax-highlighting-global-mode +1))

Vterm

Vterm is a terminal emulator within Emacs. The 'shell-file-name' setting sets the shell to be used in M-x shell, M-x term, M-x ansi-term and M-x vterm. By default, the shell is set to 'fish' but could change it to 'bash' or 'zsh' if you prefer.

 (unless (kylekrein/is-android) ;;Fails to compile
