* prelude

Startup related tasks/setup that might be used later on.

*** emacs package setup

Setup the builtin emacs package manager.

#+BEGIN_SRC emacs-lisp :tangle tmp/.emacs.d/init.el :mkdirp yes
  (require 'package)
  (package-initialize)
#+END_SRC

Add in the standard package archive urls.

#+BEGIN_SRC emacs-lisp
  (add-to-list 'package-archives '("org" . "http://orgmode.org/elpa/") t)
  (add-to-list 'package-archives '("melpa" . "http://melpa.org/packages/") t)
  (add-to-list 'package-archives '("marmalade" . "http://marmalade-repo.org/packages/") t)
#+END_SRC

*** tangle functions

Duplicated from tangle.el just to make using org easier.

TODO: make this stuff work sanely in emacs org mode and
via external tangling. Not tangled for now.

#+BEGIN_SRC emacs-lisp
  (defun tangle/yn (p) (if (bound-and-true-p p) "yes" "no"))
  (defun tangle/file (file p) (if (bound-and-true-p p) (concat "tmp/" file) "no"))
#+END_SRC

*** emacs gc speedup

#+BEGIN_SRC emacs-lisp
  (defun my-minibuffer-setup-hook ()
    (setq gc-cons-threshold most-positive-fixnum))

  (defun my-minibuffer-exit-hook ()
    (setq gc-cons-threshold 8000000))

  (add-hook 'minibuffer-setup-hook #'my-minibuffer-setup-hook)
  (add-hook 'minibuffer-exit-hook #'my-minibuffer-exit-hook)
#+END_SRC

*** use-package/diminish bootstrap

This configuration is using *use-package* extensively. Install it and diminish
straight away so we can use it elsewhere.

#+BEGIN_SRC emacs-lisp
  (unless (package-installed-p 'use-package)
    (progn
      (package-refresh-contents)
      (package-install 'use-package)
      (package-initialize)))

  (require 'use-package)
  (setq use-package-verbose t)
  (use-package diminish :ensure t)
  ;; diminish away builtin modes right away as well
  (diminish 'flyspell-mode)
  (diminish 'whitespace-mode)
  (diminish 'visual-line-mode)
#+END_SRC

*** match end of string function

#+BEGIN_SRC emacs-lisp
  (defun string/ends-with (string suffix)
    "Return t if STRING ends with SUFFIX."
    (and (string-match (rx-to-string `(: ,suffix eos) t)
                       string)
         t)
    )
#+END_SRC

*** debug on error

Not having to start *emacs* with *--debug-init* is useful.

#+BEGIN_SRC emacs-lisp
  (setq debug-on-error t)
#+END_SRC

*** emacs server

Start up the emacs server if it isn't running.

#+BEGIN_SRC emacs-lisp
  (load "server")
  (unless (server-running-p) (server-start))
#+END_SRC

*** theme

Solarized light is decent. I'll just use that. Note, to prevent flicker this is setup early in startup.

#+BEGIN_SRC emacs-lisp
  (use-package solarized-theme :ensure t :init (load-theme 'solarized-light 't))
#+END_SRC

*** os detection

Make it easier to determine what os we're running on.

#+BEGIN_SRC emacs-lisp
  (defvar on-mswindows (string-match "windows" (symbol-name system-type))
    "Am I running under windows?")
  (defvar on-osx (string-match "darwin" (symbol-name system-type))
    "Am I running under osx?")
  (defvar on-linux (string-match "gnu/linux" (symbol-name system-type))
    "Am I running under linux?")
#+END_SRC

*** disable pointless startup stuff

Like the startup screen and the echo hooey.

#+BEGIN_SRC emacs-lisp
  (custom-set-variables
   '(inhibit-startup-screen t)
   '(inhibit-startup-message t)
   '(inhibit-startup-echo-area-message t)
   )
#+END_SRC

*** temporary files

Keep temporary stuff isolated from everyone else. It infects everything otherwise. As bad as the .DS_Store files on osx.

#+BEGIN_SRC emacs-lisp
  (custom-set-variables
   '(temporary-file-directory "/tmp")
   '(backup-directory-alist `((".*" . ,temporary-file-directory)))
   '(auto-save-file-name-transforms `((".*" ,temporary-file-directory t)))
   '(create-lockfiles nil)
   '(make-backup-files nil)
   '(auto-save-default nil)
   '(backup-by-copying t)
   '(auto-save-list-file-prefix temporary-file-directory)
   '(backup-directory-alist `((".*" . ,temporary-file-directory)))
   '(auto-save-file-name-transforms `((".*" ,temporary-file-directory t)))
   )
#+END_SRC

*** auto revert

Update files in open buffers as they're changed on disk, freaking annoying without this on.

#+BEGIN_SRC emacs-lisp
  (custom-set-variables '(global-auto-revert-mode t))
#+END_SRC

*** dired

Use dired-x.

#+BEGIN_SRC emacs-lisp
  (add-hook 'dired-load-hook (function (lambda () (load "dired-x"))))
#+END_SRC

*** ediff

For those rare times I use it, make it a bit less derp on output.

#+BEGIN_SRC emacs-lisp
  (setq ediff-window-setup-function 'ediff-setup-windows-plain)
  (setq ediff-split-window-function 'split-window-horizontally)
#+END_SRC

*** always remove trailing whitespace

Trailing whitespace is not normally useful. Remove it always on save in the *before-save-hook*.

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

*** chmod u+x on save for scripts

Because its derp to have to chmod 755 stuff after I save. Honestly, do it for me kthxbai.

#+BEGIN_SRC emacs-lisp
  (add-hook 'after-save-hook 'executable-make-buffer-file-executable-if-script-p)
#+END_SRC

*** misc text related
#+BEGIN_SRC emacs-lisp
  (put 'upcase-region 'disabled nil)
#+END_SRC
*** line wrap

Line wrapping is useful. Enable it globally for a start.

Need word-wrap so kill line kills the line, not the displayed line.

#+BEGIN_SRC emacs-lisp
  (global-visual-line-mode t)
  (custom-set-variables '(word-wrap t))
#+END_SRC

*** default major mode

So if we don't know, call it text-mode.

#+BEGIN_SRC emacs-lisp
  (custom-set-variables '(default-major-mode 'text-mode))
#+END_SRC

*** encoding

utf8 is the best. Default to it.

#+BEGIN_SRC emacs-lisp
  (custom-set-variables '(locale-coding-system 'utf-8))
  (set-terminal-coding-system 'utf-8)
  (set-keyboard-coding-system 'utf-8)
  (set-selection-coding-system 'utf-8)
  (prefer-coding-system 'utf-8)
#+END_SRC

*** text selection

If I selected text, delete the selection, I probably meant it emacs.

#+BEGIN_SRC emacs-lisp
  (delete-selection-mode 1)
#+END_SRC
*** line width

80 char line columns not 72.

#+BEGIN_SRC emacs-lisp
  (custom-set-variables '(fill-column 80))
#+END_SRC

*** we aren't banging rocks together anymore emacs

Double spacing after a line isn't needed. We aren't animals emacs, we have computers.

#+BEGIN_SRC emacs-lisp
  (set-default 'sentence-end-double-space nil)
#+END_SRC

*** sentence end

Semi related to the above, make the sentence endings a bit more code-ish.

#+BEGIN_SRC emacs-lisp
  (custom-set-variables
   '(sentence-end "[.?!][]\"')]*\\($\\|\t\\| \\)[ \t\n]*")
   '(sentence-end-double-space nil)
   )
#+END_SRC

*** default tab-width

Two seems sensible, cause well, tabs are evil incarnate.

Lets use a tab width of 2 by default.

#+BEGIN_SRC emacs-lisp
  (custom-set-variables '(default-tab-width 2))
#+END_SRC

*** whitespace

Customize whitespace mode to make tabs obvious as boxes, and to highlight lines over 80 characters in length.

#+BEGIN_SRC emacs-lisp
(require 'whitespace)

(setq whitespace-style '(face tabs trailing))

(set-face-attribute 'whitespace-tab nil
                    :foreground "#2075c7"
                    :background "lightgrey")

(set-face-attribute 'whitespace-line nil
                    :foreground "#2075c7"
                    :background "lightgrey")
#+END_SRC

*** uncategorized

I have no idea how to label these.

Highlight parens.

#+BEGIN_SRC emacs-lisp
  (show-paren-mode)
#+END_SRC

Typing out *yes* or *no* is stupid.

#+BEGIN_SRC emacs-lisp
  (fset 'yes-or-no-p 'y-or-n-p)
#+END_SRC

*** osx specific

**** no yes-or-no gui windows

On osx, don't ever display the gui dialog box. Taken from http://superuser.com/questions/125569/how-to-fix-emacs-popup-dialogs-on-mac-os-x

#+BEGIN_SRC emacs-lisp
  (when (and on-osx (window-system))
    (defadvice yes-or-no-p (around prevent-dialog activate)
      "Prevent yes-or-no-p from activating a dialog"
      (let ((use-dialog-box nil))
        ad-do-it))
    (defadvice y-or-n-p (around prevent-dialog-yorn activate)
      "Prevent y-or-n-p from activating a dialog"
      (let ((use-dialog-box nil))
        ad-do-it))
    )
#+END_SRC

**** make osx gui emacs keyboard setup match console

Command should be meta on cocoa emacs like the old carbon/macports version.

#+BEGIN_SRC emacs-lisp
  (when (and on-osx (window-system))
    (custom-set-variables
     '(mac-command-key-is-meta t)
     '(mac-option-key-is-meta nil)
     '(mac-command-key-is-meta t)
     '(mac-command-modifier 'meta)
     '(mac-option-modifier 'none)
     )
    )
#+END_SRC

*** global key bindings

Global key bindings.

#+BEGIN_SRC emacs-lisp
  (global-set-key (kbd "C-x ,") 'kill-whole-line)
  (global-set-key (kbd "C-x C-m") 'compile)
#+END_SRC

*** x copy/paste

#+BEGIN_SRC emacs-lisp
  (when (and on-linux (window-system))
    (progn
      (setq interprogram-paste-function 'x-cut-buffer-or-selection-value)
      (setq x-select-enable-clipboard t)
      )
    )
#+END_SRC
* appearance
*** gui

When i'm running in a terminal emacs, most of this junk isn't needed. For that matter gui counts for most.

Basically, never show the tool bar or the scroll bar in gui or tty. In gui its ok to show the menu-bar.

Also have the scratch buffer be empty instead of have the derp message I never read anyway.

#+BEGIN_SRC emacs-lisp
  (tool-bar-mode -1)
  (scroll-bar-mode -1)
  (when (not window-system)
    (menu-bar-mode -1))
  (custom-set-variables '(initial-scratch-message nil))
#+END_SRC

*** fonts

List of fonts in order of preference.

#+BEGIN_SRC emacs-lisp
  (defvar my/gui-fonts
    '(
      "PragmataPro"
      "Pragmata Pro" ;; Seems to register differently on osx than X
      "Source Code Pro"
      "Menlo"
      "Monaco"
      )
    )
#+END_SRC

Set preferred font list when we're in a gui emacs session.

#+BEGIN_SRC emacs-lisp
  (with-no-warnings
    (when window-system
      (if (find-font  (font-spec :name (car my/gui-fonts)))
          (progn (set-frame-font (car my/gui-fonts))
                 (set-face-attribute 'default nil :height 180))
        (progn (set-gui-font (cdr my/gui-fonts))))
      )
    )
#+END_SRC

*** tty

   Enable mouse mode for the console and use the mousewheel if possible.

#+BEGIN_SRC emacs-lisp
  (unless window-system
    (require 'mouse)
    (xterm-mouse-mode t)
    (global-set-key [mouse-4] '(lambda ()
                                 (interactive)
                                 (scroll-down 1)))
    (global-set-key [mouse-5] '(lambda ()
                                 (interactive)
                                 (scroll-up 1)))
    (defun track-mouse (e))
    )
#+END_SRC

* packages

All the packages I use.

#+END_SRC

                (add-to-list 'tramp-default-proxies-alist '(".*" "\`root\'" "/ssh:%h:")))
*** exec-path-from-shell

*** auto-insert-mode new file templates

Use auto-insert-mode to insert in templates for blank files.

So first up, add auto-insert to *find-file-hooks* so we insert straight away. Also setup the copyright bit to minimally put in name.

#+BEGIN_SRC emacs-lisp
  (add-hook 'find-file-hooks 'auto-insert)
  (defvar auto-insert-copyright (user-full-name))
#+END_SRC

Create *auto-insert-alist* so all the mode lists are the same

#+BEGIN_SRC emacs-lisp
  (defvar auto-insert-alist '(()))
#+END_SRC
