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
Set up package.el to load from ELPA and MELPA
#+BEGIN_SRC emacs-lisp
  (require 'package)
  (setq package-archives
        '(("gnu" . "https://elpa.gnu.org/packages/")
          ("melpa" . "https://melpa.org/packages/")))
  (package-initialize)
#+END_SRC

`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.
#+BEGIN_SRC emacs-lisp
  (unless (package-installed-p 'use-package)
    (package-refresh-contents)
    (package-install 'use-package))
  (require 'use-package)
  (setq use-package-always-ensure t)
#+END_SRC

[[https://framagit.org/steckerhalter/quelpa][Quelpa]] extends package.el to build packages from source from a bunch of targets (git, hg, etc.).
#+BEGIN_SRC emacs-lisp
  (use-package quelpa)
  (use-package quelpa-use-package)
#+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

* 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

* 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))
#+END_SRC

* General
Better keybinding.
#+BEGIN_SRC emacs-lisp
  (use-package general)
#+END_SRC

Delete trailing whitespace on save:
#+BEGIN_SRC emacs-lisp
  (add-hook 'before-save-hook #'delete-trailing-whitespace)
#+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

Use the spacebar as a leader key in evil-mode's normal state and in various other modes:
#+BEGIN_SRC emacs-lisp
  (defconst leader "SPC")
  (general-define-key
   :states 'motion
   "SPC" nil)
  (general-create-definer leader-def-key
    :states 'motion
    :prefix leader
    :prefix-map 'leader-map)
#+END_SRC

#+BEGIN_SRC emacs-lisp
  (jdormit/define-prefix "?" "help")
  (leader-def-key "?" help-map)
#+END_SRC

Make undo not undo paragraphs at a time:
#+BEGIN_SRC emacs-lisp
  (setq evil-want-fine-undo t)
#+END_SRC

** evil-collection
A collection of evil bindings for various modes
#+BEGIN_SRC emacs-lisp
  (use-package evil-collection
    :after (evil))

  (with-eval-after-load 'dired
    (evil-collection-dired-setup))
  (with-eval-after-load 'help
    (evil-collection-help-setup)
    (general-def 'normal help-mode-map "SPC" leader-map))
#+END_SRC

** Additional keybindings
#+BEGIN_SRC emacs-lisp
  (general-def 'normal "zM" #'hs-hide-level)
#+END_SRC

* Magit
Magit is objectively the best Git interface.
#+BEGIN_SRC emacs-lisp
  (use-package magit
    :commands (magit-status magit-blame magit-find-file))
#+END_SRC

#+BEGIN_SRC emacs-lisp
  (jdormit/define-prefix "g" "git")
  (leader-def-key "gs" #'magit-status)
  (leader-def-key "gb" #'magit-blame)
  (leader-def-key "gf" #'magit-find-file)
#+END_SRC

Use ido-mode for completion within Magit:
#+BEGIN_SRC emacs-lisp
  (setq magit-completing-read-function 'magit-ido-completing-read)
#+END_SRC

** Forge
[[https://github.com/magit/forge][Forge]] is an extension for Magit that lets it interact with code forges (e.g. GitHub).
#+BEGIN_SRC emacs-lisp
  (use-package forge :quelpa
    :after (magit)
    :config
    (add-to-list 'forge-alist '("git.jeremydormitzer.com" "git.jeremydormitzer.com/api/v1"
				"git.jeremydormitzer.com" forge-gitea-repository))
    (add-to-list 'evil-emacs-state-modes 'forge-topic-list-mode)
    :general
    (forge-topic-list-mode-map "SPC" leader-map))
#+END_SRC

** evil-magit
Evil keybindings for magit!
#+BEGIN_SRC emacs-lisp
  (use-package evil-magit
    :after (evil magit forge))
#+END_SRC

* with-editor
A utility from the author of Magit to run shell commands using the current Emacs instance as $EDITOR.

#+BEGIN_SRC emacs-lisp
  (shell-command-with-editor-mode)
  (add-hook 'shell-mode-hook #'with-editor-export-editor)
  (add-hook 'term-exec-hook #'with-editor-export-editor)
  (add-hook 'eshell-mode-hook #'with-editor-export-editor)
#+END_SRC
* Password Store
Interfacing with Pass, the "standard Unix password manager". This should also be loaded before `exec-path-from-shell`.
#+BEGIN_SRC emacs-lisp
  (defun password-store-synchronize ()
    (interactive)
    (with-editor-async-shell-command "pass git pull && pass git push"))

  (use-package password-store
    :if (executable-find "pass")
    :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
    :if (executable-find "pass")
    :commands pass
    :config
    (evil-collection-pass-setup)
    :general
    (pass-mode-map "S" #'password-store-synchronize))

  (leader-def-key "ap" #'pass)
#+END_SRC

* Emacs Lisp
Requires:
#+BEGIN_SRC emacs-lisp
  (eval-when-compile (require 'subr-x))
#+END_SRC

** Editing Elisp
#+BEGIN_SRC emacs-lisp
  (general-def 'motion emacs-lisp-mode "C-c C-c" #'eval-defun)
#+END_SRC
** Load path
For machine or user specific libraries:
#+BEGIN_SRC emacs-lisp
  (add-to-list 'load-path (expand-file-name "~/site-lisp"))
#+END_SRC

And for global ones:
#+BEGIN_SRC emacs-lisp
  (add-to-list 'load-path "/usr/local/share/emacs/site-lisp")
#+END_SRC

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

Opening a file as sudo:
#+BEGIN_SRC emacs-lisp
  (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)))

#+END_SRC

Recursive =assoc= for nested alists:
#+BEGIN_SRC emacs-lisp
  (defun assoc-recursive (alist &rest keys)
    "Recursively find KEYs in ALIST."
    (while keys
      (setq alist (cdr (assoc (pop keys) alist))))
    alist)
#+END_SRC

Format a millis timestamp into human-readable form:
#+BEGIN_SRC emacs-lisp
  (defun format-epoch-millis (millis)
     (interactive "nTimestamp: ")
     (message (format-time-string "%F %r" (/ millis 1000))))
#+END_SRC

The same but for seconds:
#+BEGIN_SRC emacs-lisp
  (defun format-epoch-seconds (seconds)
     (interactive "nTimestamp: ")
     (message (format-time-string "%F %r" seconds)))
#+END_SRC

Checking if a buffer contains a string:

  (defun buffer-contains-substring (string)
    (save-excursion
      (save-match-data
	(goto-char (point-min))
	(search-forward string nil t))))
#+END_SRC

      (json-pretty-print (point-min) (point-max))
      (buffer-substring (point-min) (point-max))))
#+END_SRC

Load environment variables into Emacs from a shell script:
#+BEGIN_SRC emacs-lisp
  (defun extract-vars-from-env-file (file)
    "Extracts an alist of variable name to value from
     a bash script that exports environment variables."
    (let ((var-re "\\(.+?\\)=\\(.+\\)$")
	  (env '()))
      (with-temp-buffer
	(shell-command (concat "source " file " > /dev/null && env")

	(save-match-data
	  (while (re-search-forward var-re nil t)
	    (push (cons (match-string 1) (match-string 2)) env))))
      env))

  (defun source-env-file (file)
    (interactive "fFile: \n")
    (let (env (extract-vars-from-env-file file))
      (dolist (binding env)

#+END_SRC

Convenience macro to run some code in a particular default-directory:
#+BEGIN_SRC emacs-lisp

    (declare (indent 1))
    `(let ((default-directory ,dir))
       ,@body))
#+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
               (prin1-to-string vars-plist) nil file))
          (let ((vars-plist `(,var-name ,value)))
            (write-region
             (prin1-to-string vars-plist) nil file)))))
#+END_SRC

** Process handling
Some utilities for calling out to other processes.
#+BEGIN_SRC emacs-lisp
  (defun make-process-sentinel (success err)
    "Makes a process sentinel that calls `success` on success and `err` on error"
    (lambda (proc event)
      (cond ((string-match-p "finished" event) (funcall success))
	    (t (funcall err)))))

  (defun make-success-err-msg-sentinel (buf success-msg err-msg &optional kill-on-err)
    (make-process-sentinel
     (lambda ()
       (message success-msg)
       (kill-buffer buf))
     (lambda ()
       (message err-msg)
       (when kill-on-err
	 (kill-buffer buf)))))
#+END_SRC

A function to call a process passing some string as stdin and returning the process output:
#+BEGIN_SRC emacs-lisp
  (defun make-process-fn (program &rest args)
    "Returns a function that, when called, call `program` with arguments `args`,
     passing the function argument as stdin"
    (lambda (&optional input)
      (with-temp-buffer
	(if input
	    (progn
	      (insert input)
	      (apply #'call-process-region (point-min) (point-max) program t t nil args))
	  (apply #'call-process program nil t nil args))
	(buffer-substring-no-properties (point-min) (point-max)))))
#+END_SRC

The same function but for commands that need to run in a shell:
#+BEGIN_SRC emacs-lisp
  (defun make-shell-fn (program &rest args)
    "Returns a function that, when called, calls `program` in a shell
     with arguments `args`, passing the function argument as stdin"
    (lambda (&optional input)
      (let ((cmd (combine-and-quote-strings `(,program ,@args))))
	(with-temp-buffer
	 (if input
	     (progn
	       (insert input)
	       (call-shell-region (point-min) (point-max) cmd t t))
	   (call-process-shell-command cmd nil t))
	 (buffer-substring-no-properties (point-min) (point-max))))))
#+END_SRC

Running a shell command as sudo:
#+BEGIN_SRC emacs-lisp
  (defun sudo-shell-command (command)
    (with-temp-buffer
      (cd "/sudo::/")
      (shell-command command)))
#+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))
	(funcall fn))))

  (add-hook 'buffer-list-update-hook #'run-buffer-mode-hooks)
#+END_SRC
** Miscellaneous
#+BEGIN_SRC emacs-lisp
  (setq warning-suppress-types
	'((undo discard-info)))
#+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

* 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
  (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)"))))

#+END_SRC

Load up libraries from Dropbox, if there are any:
#+BEGIN_SRC emacs-lisp
  (add-to-list 'load-path
	 (concat
	  (file-name-as-directory (get-dropbox-directory))
	  "site-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 ()
    (interactive)
    (load-file "~/.emacs.d/init.el")
    (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:
#+BEGIN_SRC emacs-lisp
  (with-eval-after-load 'evil
    (add-to-list 'evil-emacs-state-modes 'benchmark-init/tabulated-mode)
    (add-to-list 'evil-emacs-state-modes 'benchmark-init/tree-mode)

    "Switch to previously open buffer.
  Repeated invocations toggle between the two most recently open buffers."
    (interactive)
    (switch-to-buffer (other-buffer (current-buffer) 1)))

  (leader-def-key "TAB" 'switch-to-previous-buffer)
#+END_SRC
