TODO Look at tangling at

[http://thewanderingcoder.com/2015/02/literate-emacs-configuration/]

although I'd rather do something like a local variable evaluation such as

Or makefile approach [https://emacs.stackexchange.com/questions/27126/is-it-possible-to-org-bable-tangle-an-org-file-from-the-command-line]

See also [http://orgmode.org/manual/Extracting-source-code.html#Extracting-source-code]

Some remarks and comments

setq vs setq-default

Some variables are buffer-local, others are not; for non buffer-local variables the two commands are equivalent; for the buffer-local variables, setq acts on the current buffer, whereas setq-default sets the default value of the variable for buffers that do not have a local value.

:source: [https://stackoverflow.com/a/18173666]

Why not package.el

it is convenient, but it is not git-based; borg.el is promising, but it is way complicated; I can do everything by hand as soon as it is neatly org-anized

Files and dirs

Move Customize to a separate file

  (setq custom-file "~/.emacs.d/custom.el")
  (load custom-file 'noerror)

Add relevant dirs to load path [This is somewhat undesirable; I should uniformize the path-loading business at some point…]

  (let ((default-directory "~/.emacs.d/"))
    (normal-top-level-add-subdirs-to-load-path)
    (normal-top-level-add-to-load-path '("fringe-helper.el"
                                         "multiple-cursors.el"
                                         "expand-region.el"
                                         "dash.el")))

Put autosave files (ie #foo#) and backup files (ie foo~) in ~/.emacs.d/. create the autosave dir if necessary, since emacs won't.

  (make-directory "~/.emacs.d/autosaves/" t)
  (make-directory "~/.emacs.d/backup/" t)

Themes

Use (my clone of) the solarized theme

  (add-to-list 'custom-theme-load-path "/home/jacopods/.emacs.d/emacs-color-theme-solarized")
  (load-theme 'solarized t)

Use patched terminus font (this overrides the settings in Customize, but I never could it to work otherwise). See the special treatment later on for dealing with bold weight. To avoid flickering one should also set the font in .Xresources

  (set-face-font 'default "-xos4-hackminus-medium-r-normal--20-200-72-72-c-100-ISO10646-1")

Global settings

Cosmetics

Prefer a minimal appearance: no menu, toolbar or scroll-bars; no splash screens or messages

  (menu-bar-mode -1)
  (tool-bar-mode 0)
  (scroll-bar-mode -1)
  (setq inhibit-startup-screen t
        inhibit-startup-message t)

a blinking cursor keeps the gpu awake; add global hl-line mode to more easily spot the cursor

  (blink-cursor-mode 0)
  (set-default 'cursor-type 'box)
  (global-hl-line-mode t)

Set frame title

  (setq frame-title-format
     '((buffer-file-name "%f"
         (dired-directory dired-directory "%b")) " · emacs"));; · " (:eval (kde-current-activity-name)))) ;; "%S"))

Themed tooltips

(setq x-gtk-use-system-tooltips nil)

Set Fill-column to 78, which happens to be good for third-tiled frames and it also is a reasonable standard (almost 80)

  (setq default-fill-column 78)

Mouseless

Disable mouse interaction with emacs

  (setq mouse-autoselect-window nil)
  (mouse-wheel-mode -1)
  (setq mouse-yank-at-point nil)
  (setq focus-follows-mouse nil)

TODO Find out what of the above is necessary given the disable-mouse mode below

Use the disable-mouse package by Steve Purcell available at [https://github.com/purcell/disable-mouse]

  (require 'disable-mouse)
  (global-disable-mouse-mode)

Window behavior

Prevent compilation window eating up other windows

   (setq compilation-scroll-output t
         compilation-window-height 12)

Prevent any automatic splitting to split vertically

  (setq split-width-threshold nil)

Scrolling

Scrolling setup

   (setq redisplay-dont-pause t
         scroll-margin 3
         scroll-step 1
         scroll-conservatively 10000

TODO find out what this was actually meant to do

  (setq-default display-buffer-reuse-frames t)

Modeline

  (setq-default mode-line-modified '(:eval (if (buffer-modified-p) "●" "·"))) ;still needs some improvements,
                                                                              ;does not report Readonly state
  (setq-default mode-line-remote '(:eval (let ((s (format-mode-line "%@")))
    (cond

Mark handling

No transient mark is more flexible

(transient-mark-mode 0)

But of course we need to see the mark

(require 'visible-mark)
(visible-mark-mode t)
(global-visible-mark-mode t)

The following are some convenient bindings; notice that on my layout F13 and F14 are obtained by tapping the left and right shift respectively

(global-set-key (kbd "<f13>") 'set-mark-command)
(global-set-key (kbd "<f14>") 'set-mark-command)

(defun jump-to-mark ()
  "Jumps to the local mark, respecting the `mark-ring' order.
This is the same as using \\[set-mark-command] with the prefix argument."
  (interactive)
  (set-mark-command 1))
(global-set-key (kbd "<M-f13>") 'jump-to-mark)
(global-set-key (kbd "<M-f14>") 'jump-to-mark)

(defun just-activate-mark ()
  (interactive)
  (activate-mark))
(global-set-key (kbd "<S-f13>") 'just-activate-mark)
(global-set-key (kbd "<S-f14>") 'just-activate-mark)

Global bindings

Remove some supremely annoying bindings

  (global-unset-key (kbd "C-z"))
  (global-unset-key (kbd "C-x f"))
  (global-unset-key (kbd "<M-f4>")) ; rly?

Change {up,down}-list

  (global-unset-key (kbd "C-M-u"))
  (global-unset-key (kbd "C-M-d"))
  (global-set-key (kbd "C-M-i") 'down-list) ;; -i stands for /in/
  (global-set-key (kbd "C-M-o") 'up-list)   ;; -o stands for /out/

Add some opinionated bindings

  (global-set-key (kbd "C-M-d") 'kill-sexp)
  (global-set-key (kbd "C-M-<backspace>") 'backward-kill-sexp)
  (global-set-key (kbd "C-x k") 'kill-this-buffer)
  (global-set-key (kbd "C-S-v") 'scroll-down-command)

Smart beginning-of-line

This is a relatively smart way to go back to the beginning of the line

  (defun smart-line-beginning ()
  "Move point to the beginning of text on the current line; if that
  is already the current position of point, then move it to the
  beginning of the line."
(interactive)
(let ((pt (point)))
(beginning-of-line-text)
(when (eq pt (point))
  (beginning-of-line))))
   (global-set-key (kbd "C-a") 'smart-line-beginning)

Whitespace

Trailing whitespace is evil; get rid of it

  (setq-default show-trailing-whitespace t)
  (add-hook 'before-save-hook 'delete-trailing-whitespace)

Define what is whitespace during a search

     (setq search-whitespace-regexp "[ \t\r\n]+")

Tabs are evil; get rid of them

  (setq c-basic-offset 4)
  (setq tab-width 4)
  (setq indent-tabs-mode nil)

TODO Have a look at ws-trim.el

It is conf'ble to avoid removing whitespace from lines that were not modified; sounds like a good idea for git [ftp://ftp.lysator.liu.se/pub/emacs/ws-trim.el]

Show matching parens

Use mic-paren for paren-highlighting

;     (setq show-paren-mode t)
  (require 'mic-paren)
  (paren-activate)

TODO find out if there are better options out there

Abbrevs

Set up abbrevs

   (setq-default abbrev-mode t)
   (read-abbrev-file "~/.abbrev_defs")
   (setq save-abbrevs t)

Spellcheck

Use flyspell

   (add-hook 'text-mode-hook 'flyspell-mode)
   (setq flyspell-use-meta-tab nil)

Fringe treatment

TODO try linum-relative

  (require 'linum-relative)
  (linum-relative-mode 1)

Add line numbers globally

  (global-linum-mode 1)

Highlight also the linum in the fringe

 (require 'hlinum)
 (hlinum-activate)

Add marker for current line in the fringe (see [https://github.com/kyanagi/fringe-current-line])

  ;; (require 'fringe-current-line)
  ;; (global-fringe-current-line-mode 1)
  ;; (setq fcl-fringe-bitmap 'right-triangle)

Turn on echo mode

Display unfinished commands in the echo area after the specified delay.

  (setq echo-keystrokes 0.10)

Disable completion buffer

Remove the completion buffer as soon as we get out of the minibuffer

  (add-hook 'minibuffer-exit-hook
            '(lambda ()
               (let ((buffer "*Completions*"))
                 (and (get-buffer buffer)
                      (kill-buffer buffer))) ))

  (setq compilation-ask-about-save nil)
