#+PROPERTY: header-args :results silent
#+PROPERTY: header-args:emacs-lisp :lexical t
This init file is based on [[https://medium.com/@CBowdon/pinching-the-best-bits-from-spacemacs-869b8c793ad3][this blog post]].
It's meant to be loaded from init.el like so:
#+BEGIN_SRC emacs-lisp :tangle no
(require 'org)
(org-babel-load-file (expand-file-name "path/to/init.org"))
#+END_SRC
* Prelude
Enables lexical binding for everything in init.el:
#+BEGIN_SRC emacs-lisp
;;; -*- lexical-binding: t; -*-
#+END_SRC
Requires:
#+BEGIN_SRC emacs-lisp
(require 'json)
#+END_SRC
* Default directory
#+BEGIN_SRC emacs-lisp
(cd "~")
#+END_SRC
* Packages
Use [[https://github.com/raxod502/straight.el][straight.el]] to manage packages:
#+BEGIN_SRC emacs-lisp
(defvar bootstrap-version)
(let ((bootstrap-file
(expand-file-name "straight/repos/straight.el/bootstrap.el" user-emacs-directory))
(bootstrap-version 5))
(unless (file-exists-p bootstrap-file)
(with-current-buffer
(url-retrieve-synchronously
"https://raw.githubusercontent.com/raxod502/straight.el/develop/install.el"
'silent 'inhibit-cookies)
(goto-char (point-max))
(eval-print-last-sexp)))
(load bootstrap-file nil 'nomessage))
#+END_SRC
`use-package` is a macro that simplifies installing and loading packages.
#+BEGIN_SRC emacs-lisp
(straight-use-package 'use-package)
(setq straight-use-package-by-default t)
#+END_SRC
* 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.
#+BEGIN_SRC emacs-lisp
(use-package benchmark-init
:config
(add-hook 'after-init-hook 'benchmark-init/deactivate))
#+END_SRC
* Solarized
Solarized is the best color scheme, objectively speaking:
#+BEGIN_SRC emacs-lisp
(use-package solarized-theme)
(require 'solarized-theme)
#+END_SRC
* Doom themes
#+BEGIN_SRC emacs-lisp
(use-package doom-themes)
(use-package doom-modeline
:init
(doom-modeline-mode 1))
#+END_SRC
* Customization File
I don't want anything to write to my init.el, so save customizations in a separate file:
#+BEGIN_SRC emacs-lisp
(setq custom-file (expand-file-name "custom.el" user-emacs-directory))
(load custom-file t)
#+END_SRC
* 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.
#+BEGIN_SRC emacs-lisp
(use-package exec-path-from-shell
:if (memq window-system '(mac ns x))
:config
(setq exec-path-from-shell-variables '("PATH" "MANPATH" "LEDGER_FILE" "LOLA_HOME"
"MODELS_HOME" "LOLA_TRAVEL_SERVICE_HOME" "WORKON_HOME"))
(exec-path-from-shell-initialize))
#+END_SRC
* General
Better keybinding.
#+BEGIN_SRC emacs-lisp
(use-package general
:init
(setq general-override-states '(insert
emacs
hybrid
normal
visual
motion
operator
replace)))
#+END_SRC
Delete trailing whitespace on save:
#+BEGIN_SRC emacs-lisp
(add-hook 'before-save-hook #'delete-trailing-whitespace)
#+END_SRC
* Autocompletion
There seems to be [[https://github.com/company-mode/company-mode/issues/68][some contention]] about whether autocomplete or company are better autocomplete packages. I'm going with company for now because the maintainer seems nicer...
#+BEGIN_SRC emacs-lisp
(use-package company
:config
(setq company-idle-delay 0.3)
(add-hook 'after-init-hook #'global-company-mode))
(general-def "C-M-i" #'company-complete)
(general-def "M-<tab>" #'company-complete)
#+END_SRC
* Which-key
`which-key` makes keybindings discoverable.
#+BEGIN_SRC emacs-lisp
(use-package which-key
:config
(which-key-mode))
#+END_SRC
This function defines a prefix group for `which-key` so that it doesn't display `prefix`.
#+BEGIN_SRC emacs-lisp
(defun jdormit/define-prefix (binding name)
(which-key-add-key-based-replacements
(concat leader " " binding)
name)
(which-key-add-key-based-replacements
(concat "," " " binding)
name))
#+END_SRC
* Evil Mode
Because I like modal editing and dislike RSI.
#+BEGIN_SRC emacs-lisp
(use-package evil
:init
(setq evil-want-keybinding nil)
:config
(evil-mode 1))
#+END_SRC
Make undo not undo paragraphs at a time:
#+BEGIN_SRC emacs-lisp
(setq evil-want-fine-undo t)
#+END_SRC

#+BEGIN_SRC emacs-lisp

#+END_SRC

#+BEGIN_SRC emacs-lisp

"SPC" nil)
(general-create-definer leader-def-key
:keymaps 'override
:states '(normal visual motion)
:prefix leader
:prefix-map 'leader-map)
#+END_SRC
#+BEGIN_SRC emacs-lisp
(jdormit/define-prefix "?" "help")
(leader-def-key "?" help-map)
#+END_SRC
** evil-snipe
#+BEGIN_SRC emacs-lisp
(use-package evil-snipe
:after (evil)
:config
(evil-snipe-mode 1)
(evil-snipe-override-mode 1)
(with-eval-after-load 'magit
(add-hook 'magit-mode-hook 'turn-off-evil-snipe-override-mode))
(with-eval-after-load 'prodigy
(add-hook 'prodigy-mode-hook 'turn-off-evil-snipe-mode))
(with-eval-after-load 'pass
(add-hook 'pass-mode-hook 'turn-off-evil-snipe-mode)))
#+END_SRC
** evil-commentary
Adds Evil commands to comment out lines of code:
#+BEGIN_SRC emacs-lisp
(use-package evil-commentary
:after (evil)
:config (evil-commentary-mode))
#+END_SRC
** Additional keybindings
#+BEGIN_SRC emacs-lisp

#+BEGIN_SRC emacs-lisp
(use-package transient)
#+END_SRC

Magit is objectively the best Git interface.
#+BEGIN_SRC emacs-lisp
(use-package magit

#+END_SRC

#+END_SRC
** Utilities

#+BEGIN_SRC emacs-lisp
(defun read-file (path)
"Returns the contents of the file as a string"
(with-temp-buffer
(insert-file-contents path)

#+END_SRC
Opening a file as sudo:

#+END_SRC
** 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).
#+BEGIN_SRC emacs-lisp
(defvar persisted-vars-file "~/.emacs.d/persisted-vars")
#+END_SRC
This function retrieves the plist of persisted variables or nil if it doesn't exist:
#+BEGIN_SRC emacs-lisp
(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)))))))
#+END_SRC
This function retrieves a persisted variable:
#+BEGIN_SRC emacs-lisp
(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))))
#+END_SRC
And this function persists a variable:
#+BEGIN_SRC emacs-lisp
(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

(let ((vars-plist `(,var-name ,value)))

#+END_SRC
** Process handling
Some utilities for calling out to other processes.
#+BEGIN_SRC emacs-lisp

#+END_SRC
A function to call a process passing some string as stdin and returning the process output:
#+BEGIN_SRC emacs-lisp

"Returns a function that, when called, call `program` with arguments `args`,
passing the function argument as stdin"
(lambda (&optional input)

#+END_SRC
The same function but for commands that need to run in a shell:
#+BEGIN_SRC emacs-lisp

"Returns a function that, when called, calls `program` in a shell
with arguments `args`, passing the function argument as stdin"
(lambda (&optional input)

(with-temp-buffer
(if input

(insert input)

#+END_SRC
Running a shell command as sudo:
#+BEGIN_SRC emacs-lisp

#+END_SRC
** Buffer switch hooks
I want to be able to run code whenever I switch to a buffer running certain modes. The code to run is stored in a alist mapping mode names to lists of code to run (stored as a raw data structure to be eval'ed):
#+BEGIN_SRC emacs-lisp
(defvar buffer-mode-hooks '())
#+END_SRC
To add a new hook, push the code to run onto the correct list:
#+BEGIN_SRC emacs-lisp
(defun add-buffer-mode-hook (mode fn)
(if-let ((existing-entry (assoc mode buffer-mode-hooks)))
(push fn (cdr existing-entry))
(let ((new-entry `(,mode . (,fn))))
(push new-entry buffer-mode-hooks))))
#+END_SRC
Whenever the buffer changes, look up the major-mode to see if there is any code to run:
#+BEGIN_SRC emacs-lisp
(defun run-buffer-mode-hooks ()
(when-let ((entry (assoc major-mode buffer-mode-hooks)))
(dolist (fn (cdr entry))

#+END_SRC
** Miscellaneous
#+BEGIN_SRC emacs-lisp
(setq warning-suppress-types

#+END_SRC
* 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:
#+BEGIN_SRC emacs-lisp

#+END_SRC
* Init File
A function to reload my init file. It reloads the major mode after the init file is loaded to rebind keymappings.
#+BEGIN_SRC emacs-lisp
(defun reload-init-file ()

(funcall major-mode))
#+END_SRC
And another one to edit it:
#+BEGIN_SRC emacs-lisp
(defun find-init-file ()
(interactive)
(find-file "~/init.org"))
#+END_SRC
* 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:
