#+PROPERTY: header-args    :results silent

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

* 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"))
    (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

* 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
    :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

* Password Store
Interfacing with Pass, the "standard Unix password manager". This should also be loaded before `exec-path-from-shell`.
#+BEGIN_SRC emacs-lisp
  (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"))
#+END_SRC

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

Default to lexical binding:
#+BEGIN_SRC emacs-lisp
  (setq lexical-binding t)
#+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 "%x %X" (/ millis 1000))))
#+END_SRC

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

* 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
  (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 'neotree-mode)

  (add-to-list 'evil-emacs-state-modes 'pass-mode)
  (add-to-list 'evil-emacs-state-modes 'picture-mode)
  (add-to-list 'evil-emacs-state-modes 'geiser-debug-mode)

  (add-to-list 'evil-emacs-state-modes 'makey-key-mode)
  (add-to-list 'evil-emacs-state-modes 'term-mode)
#+END_SRC

And in some modes I want to preserve the spacebar as a leader key:
#+BEGIN_SRC emacs-lisp
  (general-def picture-mode-map "SPC" leader-map)
  (general-def 'motion Info-mode-map "SPC" leader-map)
#+END_SRC

** Visual line navigation

  (leader-def-key "wm" 'delete-other-windows)
  (leader-def-key "wd" 'delete-window)
#+END_SRC

** Buffer commands
A function to switch to previous buffer from [[http://emacsredux.com/blog/2013/04/28/switch-to-previous-buffer/][this blog post]]:
#+BEGIN_SRC emacs-lisp
  (defun switch-to-previous-buffer ()
    "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

A function to kill all buffers except the current one from [[https://www.emacswiki.org/emacs/KillingBuffers#toc2][EmacsWiki]]:

  (jdormit/define-prefix "t" "toggle")
#+END_SRC

Toggles about line truncation:

  (leader-def-key "sa" 'ansi-term)
#+END_SRC

** Applications

  (leader-def-key "tn" 'display-line-numbers-mode)
#+END_SRC

** Org mode links
First, keep a reference to filename of the .epub before nov.el blows it away:
#+BEGIN_SRC emacs-lisp
  (defvar nov-epub-file)
  (add-hook 'nov-mode-hook
            #'(lambda ()
                (message "epub file: " buffer-file-name)
                (setq nov-epub-file buffer-file-name)))
#+END_SRC

That reference lets us construct a link back to the .epub:
#+BEGIN_SRC emacs-lisp
  (defun org-epub-store-link ()
    (when (eq major-mode 'nov-mode)
      (let ((epub-name (alist-get 'title nov-metadata)))
        (org-store-link-props
         :type "file"
         :link (concat "file://" nov-epub-file)))))

  (add-hook 'org-store-link-functions 'org-epub-store-link)
#+END_SRC

* Dashboard

#+BEGIN_SRC emacs-lisp
