1 init.el
This section generates the init.el file in the .emacs.d directory. Emacs reads this file on startup.
Because init.el is generated afresh whenever org-babel-tangle
is
called, and because the default behavior of emacs is to
programmatically place customizations at the end of the init.el
file, it is prudent to set a custom-file
location explicitly.
After setting custom file, emacs is configured. Because many other configuration options depend on properly configured packages, the packages are setup first. After that, the order of the setup operations is more or less insignificant.
;;;; init.el ;;;; DO NOT EDIT: This file has been generated by org-babel-tangle ;;;; from a source file called init-el.org.

2 Leader Keys
<<my-leader-key-system>> <<my-leader-key-toplevel-menu>> <<my-leader-key-major-mode-menu>> <<my-leader-key-applications-menu>>
I have written a custom leader key system called "my-leader-keys". A leader key system emulates menus. An initial key (M-m for me) opens the top level menu. The menu presents a key to press that either leads to the next menu or run a specific interative function.
It all starts with the def-my-command
macro, which associates a key
to a menu of commands. Each 'command' is just an interactive function.
2.1 My Leader Keys Definition
;; Leader Keys System (setq lexical-binding t) (defmacro def-my-command (name forms) `(defun ,name (ch) (interactive (let ((input (read-char (my-prompt-string ,forms)))) (list input))) (let ((command (assoc ch ,forms))) (when command (call-interactively (caddr command)))))) ;; a helper function for navigating command menus (defun my-prompt-string (&optional forms) (concat "Options: " (mapconcat 'identity (mapcar #'cadr (if forms forms *my-leader-command-forms*)) ", ")))
2.2 My Leader Key Toplevel Menu
The leader key system wouldn't be much good without a top-level leader key. Here the inital leader key menu is defined and bound to M-m.
;; Leader Key Entry Point (setq imenu-auto-rescan t) (def-my-command my-leader-command '((?/ "[/] search buffer" swiper) (?q "[q]uery replace" query-replace) (?i "[i]nsert" my-special-insert) (?'

3.4 Org Protocol Config
Following the guide here about setting up org protocol and emacs server.
This allows emacs to intercept org protocol requests from emacsclient in order to take some actions. I'm using it here as part of a DIY read-it-later app - I can push a button in my web browser and cache an article for later reading.
3.4.1 Org init.el config
First, update the config
(server-start) (require 'org-protocol)
3.4.2 desktop entry
Second, make an org-protocol desktop entry
[Desktop Entry] Name=org-protocol Comment=Intercept calls from emacsclient to trigger custom actions Categories=Other; Keywords=org-protocol; Icon=emacs Type=Application Exec=emacsclient -- %u Terminal=false StartupWMClass=Emacs MimeType=x-scheme-handler/org-protocol;
and tell your system about it. You might need to install something:
sudo apt-get install desktop-file-utils
Then run this:
update-desktop-database ~/.local/share/applications/
Finally, to actually use it, make a book mark like so:
e.g. here's one for org capture
javascript:location.href='org-protocol://capture:/w/'+encodeURIComponent(location.href)+'/'+encodeURIComponent(document.title)+'/'+encodeURIComponent(window.getSelection())
4 UI

4.1 Fonts
(add-to-list 'default-frame-alist '(font . "Comic Mono-12") ;'(font . "Victor Mono-10") )
4.2 UI Chrome
I like for my emacs to have as little UI chrome as possible, and to have a consistent UI experience. So I disable the blinking cursor, I set cursor type to 'box by default, and I disable menu, tool, and scroll bars.
;; UI Chrome (blink-cursor-mode 0) (setq-default cursor-type 'box) (menu-bar-mode 0) (tool-bar-mode 0) (scroll-bar-mode -1) (toggle-frame-maximized) ; (toggle-frame-fullscreen) (defun transparency (value) "Sets the transparency of the frame window. 0=transparent/100=opaque" (interactive (let* ((prompt (concat "Transparency Value 0 - 100 opaque [" (prin1-to-string (frame-parameter (selected-frame) 'alpha)) "]:")) (input (read-number prompt))) (list input))) (set-frame-parameter (selected-frame) 'alpha value))
4.3 Modeline Config
;; (package-install 'doom-modeline) ;; (require 'doom-modeline) ;; (doom-modeline-mode 1)
4.4 Tweaks
Bits and bobs.
I globally unset the C-z keybinding because it is easy to hit by accident and causes the window to suddenly close.
In addition, for some programming langauges, tabs should not be used to perform indtentation of source code. To ensure that no indentation does not, by default, use tabs, I set indent-tabs-mode to nil.
(global-unset-key (kbd "<Scroll_Lock>")) (global-unset-key "\C-z") (setq-default indent-tabs-mode nil) (global-hl-line-mode 1)
