enlight

Highly customizable startup screen for Emacs.

Pros:

• lightweight (enlight: 100 loc, enlight-menu: 170 loc) and fast
• no external dependencies (except for compat)
• very flexible. enlight-content custom is just a string and you decide what to put into it. That might be just a reminder with a list of tasks to do today. Or a menu with your often used commands. Or a full-blown dashboard with a lot of useful (or not) blocks of information (org-agenda, notmuch new emails count, whatever). See the screenshots below.

Installation

This package is available on MELPA.

M-x package-install enlight

Usage

Opening at startup

You can set initial-buffer-choice custom variable to #'enlight in order to show enlight right after Emacs startup:

(setopt initial-buffer-choice #'enlight)

Opening manually

Also you always can switch to the buffer by calling

M-x enlight-open

By default, it will open the buffer in the current window, but you can change the behaviour by customizing display-buffer-alist variable.

Screenshots and configuration examples

Simple menu

(use-package enlight
  :custom
  (enlight-content
   (concat
    (propertize "MENU" 'face 'highlight)
    "\n"
    (enlight-menu
     '(("Org Mode"
	("Org-Agenda (current day)" (org-agenda nil "a") "a"))
       ("Downloads"
	("Transmission" transmission "t")
	("Downloads folder" (dired "~/Downloads") "a"))
       ("Other"
	("Projects" project-switch-project "p")))))))

Using grid.el

You can use grid.el to construct a bit more complex layouts.

(use-package grid
  :init
  (unless (package-installed-p 'grid)
    (package-vc-install
     '(grid
       :vc-backend Git
       :url "https://github.com/ichernyshovvv/grid.el"
       :branch "master"))))

Two menus placed side by side

(require 'grid)

(use-package enlight
  :custom
  (enlight-content
   (grid-get-row
    `(,(enlight-menu
        '(("Org Mode"
           ("Org-Agenda (current day)" (org-agenda nil "a") "a"))
          ("Downloads"
           ("Transmission" transmission "t")
           ("Downloads folder" (dired "~/Downloads") "a"))
          ("Other"
           ("Projects" project-switch-project "p"))))
      "   "
      ,(enlight-menu
        `(("Enlight Settings"
           ("Jump to the config"
            (progn
              (find-file ,user-init-file)
              (goto-char (point-min))
              (search-forward "use-package enlight"))
            "j")
           ("Update"
            (let ((beg (point)))
              (with-current-buffer
                  (find-file-noselect ,user-init-file)
                (goto-char (point-min))
                (search-forward "use-package enlight")
                (eval-defun nil)
                (enlight))
              (goto-char beg))
            "g"))))))))

For evil users

This package does not work properly in evil mode. Feel free to send a PR to evil-collection. I have no any experience either in using evil mode or writing evil integrations.

Thanks to @a13 and @progfolio for code review.
