This init file is based on this blog post.
It's meant to be loaded from init.el like so:
(require 'org)
(org-babel-load-file (expand-file-name "path/to/init.org"))Packages
Set up package.el to load from ELPA and MELPA
(require 'package)
(setq package-archives
'(("gnu" . "https://elpa.gnu.org/packages/")
("melpa" . "https://melpa.org/packages/")))
(package-initialize)`use-package` is a macro that simplifies installing and loading packages. `use-package-always-ensure` makes sure that all packages will be installed before loading is attempted.
(unless (package-installed-p 'use-package)
(package-refresh-contents)
(package-install 'use-package))
(require 'use-package)
(setq use-package-always-ensure t)Quelpa extends package.el to build packages from source from a bunch of targets (git, hg, etc.).
(use-package quelpa)
(use-package quelpa-use-package)Benchmarking
`benchmark-init` does what it says on the box. This sets it up to benchmark my init time and then disable benchmarking after init completes.
(use-package benchmark-init
:config
(add-hook 'after-init-hook 'benchmark-init/deactivate))Path
`exec-path-from-shell` uses Bash to set MANPATH, PATH, and exec-path from those defined in the user's shell config. This won't work on Windows.
(use-package exec-path-from-shell
:if (memq window-system '(mac ns x))
:config
(setq exec-path-from-shell-variables '("PATH" "MANPATH" "LEDGER_FILE"))
(exec-path-from-shell-initialize))Autocompletion
There seems to be some contention about whether autocomplete or company are better autocomplete packages. I'm going with company for now because the maintainer seems nicer…
(use-package company
:config
(setq company-idle-delay 0.3)
(add-hook 'after-init-hook #'global-company-mode))General
Better keybinding.
(use-package general)Which-key
`which-key` makes keybindings discoverable.
(use-package which-key
:config
(which-key-mode))This function defines a prefix group for `which-key` so that it doesn't display `prefix`.
(defun jdormit/define-prefix (binding name)
(which-key-add-key-based-replacements
(concat leader " " binding)
name))Evil Mode
Because I like modal editing and dislike RSI.
(use-package evil
:config
(evil-mode 1))Use the spacebar as a leader key in evil-mode's normal state and in various other modes:
(defconst leader "SPC")
(general-define-key
:states 'motion
"SPC" nil)
(general-create-definer leader-def-key
:states 'motion
:prefix leader
:prefix-map 'leader-map) (jdormit/define-prefix "?" "help")
(leader-def-key "?" help-map)Make undo not undo paragraphs at a time:
(setq evil-want-fine-undo t)Password Store
Interfacing with Pass, the "standard Unix password manager". This should also be loaded before `exec-path-from-shell`.
(use-package password-store
:commands (password-store-list
password-store-get
password-store-copy)
:config
(setq password-store-password-length 20))
(leader-def-key "p" 'password-store-copy)
(use-package pass
:commands pass
:general
(pass-mode-map "SPC" leader-map))
(leader-def-key "ap" 'pass)
(defun password-store-synchronize ()
(interactive)
(async-shell-command "pass git pull && pass git push"))Emacs Lisp
Requires:
(eval-when-compile (require 'subr-x))Default to lexical binding:
(setq lexical-binding t)Load path
For machine or user specific libraries:
(add-to-list 'load-path (expand-file-name "~/site-lisp"))And for global ones:
(add-to-list 'load-path "/usr/local/share/emacs/site-lisp")Utilities
Reading a file as a string:
(defun read-file (path)
"Returns the contents of the file as a string"
(with-temp-buffer
(insert-file-contents path)
(buffer-string)))Opening a file as sudo:
(defun sudo-find-file (file-name)
"Like find file, but opens the file as root."
(interactive "F")
(let ((tramp-file-name (concat "/sudo::" (expand-file-name file-name))))
(find-file tramp-file-name)))
Recursive assoc for nested alists:
(defun assoc-recursive (alist &rest keys)
"Recursively find KEYs in ALIST."
(while keys
(setq alist (cdr (assoc (pop keys) alist))))
alist)Format a millis timestamp into human-readable form:
(defun format-epoch-millis (millis)
(interactive "nTimestamp: ")
(message (format-time-string "%x %X" (/ millis 1000))))The same but for seconds:
(defun format-epoch-seconds (seconds)
(interactive "nTimestamp: ")
(message (format-time-string "%x %X" seconds)))Persisting variables between session
The idea behind this is pretty simple - variables get persisted in ~/.emacs.d/<persisted-vars-file> as a plist of (variable-name variable-value).
(defvar persisted-vars-file "~/.emacs.d/persisted-vars")This function retrieves the plist of persisted variables or nil if it doesn't exist:
(defun get-persisted-plist ()
(let ((file (expand-file-name persisted-vars-file)))
(when (file-exists-p file)
(let ((vars-plist-str (read-file file)))
(unless (string= vars-plist-str "")
(car (read-from-string vars-plist-str)))))))This function retrieves a persisted variable:
(defun get-persisted-var (var-name)
"Retrieves the value of persisted variable `var-name`, or nil if not found"
(let ((vars-plist (get-persisted-plist)))
(when vars-plist
(plist-get vars-plist var-name))))And this function persists a variable:
(defun persist-variable (var-name value)
(let ((file (expand-file-name persisted-vars-file))
(vars-plist (get-persisted-plist)))
(if vars-plist
(progn
(plist-put vars-plist var-name value)
(write-region
(prin1-to-string vars-plist) nil file))
(let ((vars-plist `(,var-name ,value)))
(write-region
(prin1-to-string vars-plist) nil file)))))Dropbox
I put lots of stuff in Dropbox, but the actual folder location differs on my different computers. This function resolves to the Dropbox directory:
(defun get-dropbox-directory ()
(cond
((file-exists-p (expand-file-name "~/Dropbox"))
(expand-file-name "~/Dropbox"))
((file-exists-p (expand-file-name "~/Dropbox (Personal)"))
(expand-file-name "~/Dropbox (Personal)"))))Load up libraries from Dropbox, if there are any:
(add-to-list 'load-path
(concat
(file-name-as-directory (get-dropbox-directory))
"site-lisp"))Init File
A function to reload my init file. It reloads the major mode after the init file is loaded to rebind keymappings.
(defun reload-init-file ()
(interactive)
(load-file "~/.emacs.d/init.el")
(funcall major-mode))And another one to edit it:
(defun find-init-file ()
(interactive)
(find-file "~/init.org"))Keybindings
These are general keybindings; those specific to certain packages are in the sections for those packages.
In some modes I want vanilla Emacs bindings:
(add-to-list 'evil-emacs-state-modes 'dired-mode)
(add-to-list 'evil-emacs-state-modes 'benchmark-init/tabulated-mode)
(add-to-list 'evil-emacs-state-modes 'benchmark-init/tree-mode)

(add-to-list 'evil-emacs-state-modes 'makey-key-mode)
(add-to-list 'evil-emacs-state-modes 'term-mode)And in some modes I want to preserve the spacebar as a leader key:
