This is (will be) my Emacs literate configuration file. A self
contained file with all my configuration is useful for documentation
purposes. It will be modeled using the technique described by
Protesilaos for his own Emacs config file:
<https://protesilaos.com/emacs/dotemacs>.
This method consists in generating all files /a priori/, after modifying
this file, and *not* at load time, as that would be too slow.
#+begin_src emacs-lisp :tangle no :results none
(org-babel-tangle)
#+end_src
* Directory and file structure
- =early-init.el=: quoting the [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Early-Init-File.html][Emacs documentation]], this file is "loaded
before the package system and GUI is initialized, so in it you can
customize variables that affect the package initialization process"
- =init.el=: the skeleton of my configuration framework. It will load
the rest of the modules.
- =rul-emacs-modules/=: a directory with Emacs modules specific to my
configuration. Modules group code related to a topic or theme of
configuration. For example, =rul-prog.el= contains code related to
programming, and =rul-org.el= contains code related to org-mode. If a
module gets too big, I can create a smaller module under the same
topic; for example, =rul-org-agenda.el=.
- =rul-post-init.el=: this file will be loaded after =init.el=, and will
normally live in other git repository. Here I normally add overrides
needed in my work computer.
- =rul-emacs.org=: this file. It (will) generate the rest of the structure.
* The early init
** Graphical aspects
Customization of graphical aspects of Emacs, such as size, panels, etc.
#+begin_src emacs-lisp :tangle "early-init.el"
;; I don't use any of these
(menu-bar-mode -1)
(tool-bar-mode -1)
(scroll-bar-mode -1)
;; Avoid initial flash of light.
;; Inspired on prot-emacs-avoid-initial-flash-of-light.
(setq mode-line-format nil)
(set-face-attribute 'default nil :background "#000000" :foreground "#ffffff")
(set-face-attribute 'mode-line nil :background "#000000" :foreground "#ffffff" :box 'unspecified)
#+end_src
** Frame configuration
I like to keep a few frames open all the time. A main frame, where I
open my org files, code, etc. A frame for communication and reading,
such as email and feeds, and a frame for terminals.
Currently, the frames are all the same, but I will add configuration
to distinguish them so I can automate their placement in my desktop
environment.
#+begin_src emacs-lisp :tangle "early-init.el"
;; Do not resize when font size changes
(setq frame-resize-pixelwise t)
;; By default, start maximized
(add-to-list 'default-frame-alist '(fullscreen . maximized))
;; No need for titlebar
(modify-frame-parameters nil '((undecorated . t)))
;; Name frames to ease switching between them
(add-hook 'after-init-hook (lambda () (set-frame-name "main")))
#+end_src
** Miscellany
#+begin_src emacs-lisp :tangle "early-init.el"
;; Initialise installed packages, otherwise, basic functions are not
;; available during the initialization stage.
(setq package-enable-at-startup t)
;; Do not report warnings. It's too noisy.
(setq native-comp-async-report-warnings-errors 'silent)
;; Keep things minimal
(setq inhibit-startup-screen t)
(setq inhibit-startup-echo-area-message user-login-name)
