** General functions
:PROPERTIES:

:END:
The following functions are used throughout my config, and so I load
them first.
*** safe-load
safe-load does not break emacs initialization, should a file be
unreadable while emacs boots up.
#+BEGIN_SRC emacs-lisp
(defvar safe-load-error-list ""
        "*List of files that reported errors when loaded via safe-load")

(defun safe-load (file &optional noerror nomessage nosuffix)
  "Load a file.  If error on load, report back, wait for
   a key stroke then continue on"
  (interactive "f")
  (condition-case nil (load file noerror nomessage nosuffix)
    (error
      (progn
       (setq safe-load-error-list  (concat safe-load-error-list  " " file))
       (message "****** [Return to continue] Error loading %s" safe-load-error-list )
        (sleep-for 1)
       nil))))

(defun safe-load-check ()
 "Check for any previous safe-load loading errors.  (safe-load.el)"
  (interactive)
  (if (string-equal safe-load-error-list "") ()
               (message (concat "****** error loading: " safe-load-error-list))))
#+END_SRC
*** Local autoloads
I have some stuff put away in my local dir. I don't want to load it all
at startup time, so it is using the autoload feature. For that to work
load the loaddefs, so autoload knows where to grab stuff
#+BEGIN_SRC emacs-lisp
(safe-load (concat jj-elisp-dir "/tiny/loaddefs.el"))
(safe-load (concat jj-elisp-local-dir "/loaddefs.el"))
#+END_SRC
*** add-auto-mode
Handier way to add modes to auto-mode-alist
#+BEGIN_SRC emacs-lisp
(defun add-auto-mode (mode &rest patterns)
  "Add entries to `auto-mode-alist' to use `MODE' for all given file `PATTERNS'."
  (dolist (pattern patterns)
    (add-to-list 'auto-mode-alist (cons pattern mode))))
#+END_SRC

#+BEGIN_SRC emacs-lisp

#+END_SRC
*** hook-into-modes

#+BEGIN_SRC emacs-lisp
(defmacro hook-into-modes (func modes)
  `(dolist (mode-hook ,modes)
     (add-hook mode-hook ,func)))
#+END_SRC

*** elpa
The Emacs Lisp Package Archive contains things I want.
#+BEGIN_SRC emacs-lisp

  (require 'package)
  (setq package-user-dir (expand-file-name "elpa" jj-elisp-dir))

))
    (add-to-list 'package-archives source t))
  (package-initialize)
)
#+END_SRC

** Path settings
*** Load path
We need to define the load-path. As I have lots of things I add
locally, its getting a few entries. I disliked the repeated
/add-to-list/ lines, so I now just take all subdirectories of
jj-elisp-dir and add them.

#+BEGIN_SRC emacs-lisp
(dolist
    (project (directory-files jj-elisp-dir t "\\w+"))
  (when (file-directory-p project)
    (if (string= project "emacs23")
        (when (version< emacs-version "24")
          (add-to-list 'load-path project))
      (add-to-list 'load-path project))
    ;(byte-recompile-directory project 0)
   ))
#+END_SRC

*** Info path
Help emacs to find the info files
#+BEGIN_SRC emacs-lisp :tangle no
(setq Info-directory-list (cons jj-info-dir
                                '("/usr/local/share/info/"

                                  "/usr/share/info/"
                                  "/usr/share/info/")))

#+END_SRC

** Interface related
*** General stuff
:PROPERTIES:
:ID: 0a1560d9-7e55-47ab-be52-b3a8b8eea4aa
:END:
I dislike the startup message
#+BEGIN_SRC emacs-lisp
(setq inhibit-splash-screen t)
(setq inhibit-startup-message t)
#+END_SRC

Usually I want the lines to break at 72 characters.
#+BEGIN_SRC emacs-lisp
(setq fill-column 72)
#+END_SRC

And it is nice to have a final newline in files.
(Now off, ethan-wspace is doing it better).
#+BEGIN_SRC emacs-lisp
(setq require-final-newline nil)
(setq mode-require-final-newline nil)
#+END_SRC

After I typed 300 characters or took a break for more than a minute it
would be nice of emacs to save whatever I am on in one of its auto-save
backups. See [[info:emacs#Auto%20Save%20Control][info:emacs#Auto Save Control]] for more details.
#+BEGIN_SRC emacs-lisp
(setq auto-save-interval 300)
(setq auto-save-timeout   60)
#+END_SRC

Set my full name and my default mail address - for whatever wants to use
it later. Also, I am using gnus.
#+BEGIN_SRC emacs-lisp
(setq user-full-name "Joerg Jaspert")
(setq user-mail-address "joerg@ganneff.de")
(setq mail-user-agent (quote gnus-user-agent))
#+END_SRC

My default mail server. Well, simply a localhost, I have a forwarder that
puts mail off the right way, no need for emacs to have any further
knowledge here.
#+BEGIN_SRC emacs-lisp
(setq smtpmail-default-smtp-server "localhost")
(setq smtpmail-smtp-server "localhost")
#+END_SRC

Enable automatic handling of compressed files.
#+BEGIN_SRC emacs-lisp

#+END_SRC

Emacs forbids a certain set of commands, as they can be very confusing
for new users. Enable them.
#+BEGIN_SRC emacs-lisp

#+END_SRC

*** Look / Theme
I've tried various different fonts and while I like the Terminus font
most for my shells, in Emacs Inconsolata clearly wins.
#+BEGIN_SRC emacs-lisp
(set-frame-font "Inconsolata-14")
#+END_SRC

I always use dark backgrounds, so tell Emacs about it. No need to
guess around.
#+BEGIN_SRC emacs-lisp
(setq-default frame-background-mode jj-color-style)
#+END_SRC

And I always liked dark backgrounds with colors setup for them. So I
switched through multiple themes doing it in emacs too, but never
entirely liked it. Until I found solarized, which is now not only my
emacs theme, but also for most of my other software too, especially my
shell. Consistent look is great.
#+BEGIN_SRC emacs-lisp :tangle no

I do not want my cursor to blink.
#+BEGIN_SRC emacs-lisp

#+END_SRC
*** Menu, Tool and Scrollbar
I don't want to see the menu-bar, tool-bar or scrollbar.
#+BEGIN_SRC emacs-lisp
(when window-system
  (dolist (mode '(menu-bar-mode tool-bar-mode scroll-bar-mode))
  (when (fboundp mode) (funcall mode -1))))
#+END_SRC
**** When using emacs in daemon mode
Emacs has a very nice mode where it detaches itself and runs as daemon -
and you can just open /frames/ (windows) from it by using [[http://www.emacswiki.org/emacs/EmacsClient][Emacs
Client]]. It's fast, it's nice, it's convinient.

Except that Emacs behaves stupid when you do that and ignores your
menu/tool/scrollbar settings. Sucks.

For them to work even then, we have to do two things.
1. We have to set the frame alist. We simple set both,
   =initial-frame-alist= and =default-frame-alist= to the same value here.
   #+BEGIN_SRC emacs-lisp
  (setq initial-frame-alist '(
                              (horizontal-scroll-bars . nil)
                              (vertical-scroll-bars . nil)
                              (menu-bar-lines . 0)
                              ))
  (setq default-frame-alist (copy-alist initial-frame-alist))
#+END_SRC
2. We have to disable the toolbar using the customize interface, so you
   can find that in the [[id:0102208d-fdf6-4928-9e40-7e341bd3aa3a][Customized variables]] section.

*** Hilight current line in buffer
As it says, it does a hilight of the current line.
#+BEGIN_SRC emacs-lisp
(global-hl-line-mode +1)
#+END_SRC
*** Allow recursive minibuffers
This allows (additional) minibuffer commands while in the minibuffer.
#+BEGIN_SRC emacs-lisp
(setq enable-recursive-minibuffers 't)
#+END_SRC

*** Modeline related changes
I want to see line and column numbers, so turn them on.
Size indication lets me know how far I am in a buffer.

And modeline-posn is great. It will hilight the column number in the
modeline in red as soon as you are over the defined limit.


#+BEGIN_SRC emacs-lisp
(line-number-mode 1)
(column-number-mode 1)
(size-indication-mode 1)
(display-time-mode 1)
(setq display-time-day-and-date nil)
(setq display-time-default-load-average nil)
(setq display-time-24hr-format t)
(setq modelinepos-column-limit 72)

(use-package modeline-posn
  :ensure modeline-posn
  :config
  (progn
    (set-face-foreground 'modelinepos-column-warning "grey20")
    (set-face-background 'modelinepos-column-warning "red")
    (setq modelinepos-column-limit 72))
  )
#+END_SRC

**** diminish
[2013-04-22 Mon 11:27]
The modeline is easily cluttered up with stuff I don't really need to
see. So lets hide those. There are two ways, one of them uses diminish
to get entirely rid of some modes, the other is a function taken from
"Mastering Emacs" which replaces the modes text with an own (set of)
character(s).
#+BEGIN_SRC emacs-lisp
  (require 'diminish)
  (diminish 'auto-fill-function)
  (defvar mode-line-cleaner-alist
    `((auto-complete-mode . " α")
      (yas-minor-mode . " y")
      (paredit-mode . " π")
      (eldoc-mode . "")
      (abbrev-mode . "")
      ;; Major modes
      (lisp-interaction-mode . "λ")
      (hi-lock-mode . "")
      (python-mode . "Py")
      (emacs-lisp-mode . "EL")
      (org-mode . "Ω")
      (org-indent-mode . "")
      (sh-mode . " Σ")
      (nxhtml-mode . "nx")
      (subword-mode . ""))

    "Alist for `clean-mode-line'.

  When you add a new element to the alist, keep in mind that you
  must pass the correct minor/major mode symbol and a string you
  want to use in the modeline *in lieu of* the original.

  Want some symbols? Go:

  ;ςερτζθιοπασδφγηξκλυχψωβνμ

#+END_SRC
Unfortunately icicles breaks this with the way it adds/removes itself,
so take it our for now...

*** Default mode
Back when I started with text-mode. But nowadays I want default mode to
be org-mode - it is just so much better to use. And does sensible things
with many README files out there, and various other "crap" you get to
read in emacs.
#+BEGIN_SRC emacs-lisp :tangle yes

** aggressive-indent
[2014-10-27 Mon 13:08]
electric-indent-mode is enough to keep your code nicely aligned when
all you do is type. However, once you start shifting blocks around,
transposing lines, or slurping and barfing sexps, indentation is bound
to go wrong.

aggressive-indent-mode is a minor mode that keeps your code always
indented. It reindents after every command, making it more reliable
than electric-indent-mode.

** cua
I know that this lets it look "more like windows", but I don't much care
about its paste/copy/cut keybindings, the really nice part is the great
support for rectangular regions, which I started to use a lot since I
know this mode. The normal keybindings for those are just to useless.

Luckily cua-mode easily supports this, with the following line I just
get the CUA selection and rectangle stuff, not the keybindings. Yes,
even though the above =cua-enable-cua-keys= setting would only enable
them if the selection is done when the region was marked with a shifted
movement keys.

golden-ratio helps on this issue by resizing automatically the windows
you are working on to the size specified in the "Golden Ratio". The
window that has the main focus will have the perfect size for editing,
while the ones that are not being actively edited will be re-sized to
a smaller size that doesn't get in the way, but at the same time will
be readable enough to know it's content.

** hydra
[2015-01-26 Mon 15:50]
This is a package for GNU Emacs that can be used to tie related
commands into a family of short bindings with a common prefix - a
Hydra.

Once you summon the Hydra through the prefixed binding (the body + any
one head), all heads can be called in succession with only a short
extension.

The Hydra is vanquished once Hercules, any binding that isn't the
Hydra's head, arrives. Note that Hercules, besides vanquishing the
Hydra, will still serve his orignal purpose, calling his proper
command. This makes the Hydra very seamless, it's like a minor mode
that disables itself auto-magically.

*** General settings
[2013-04-28 So 17:06]

I use org-mode a lot and, having my config for this based on [[*Bernt%20Hansen][the config of Bernt Hansen]],
it is quite extensive. Nevertheless, it starts out small, loading it.
#+BEGIN_SRC emacs-lisp
(require 'org)

that we need org-protocol.

*** Agenda

My current =org-agenda-files= variable only includes a set of
directories.
#+BEGIN_SRC emacs-lisp
(setq org-agenda-files (quote ("~/org/"
                               "~/org/debian"

                               "~/org/spi"
                               "~/org/nsb"

#+END_SRC
=org-mode= manages the =org-agenda-files= variable automatically using
=C-c [= and =C-c ]= to add and remove files respectively.  However,
this replaces my directory list with a list of explicit filenames
instead and is not what I want.  If this occurs then adding a new org
file to any of the above directories will not contribute to my agenda
and I will probably miss something important.

I have disabled the =C-c [= and =C-c ]= keys in =org-mode-hook= to
prevent messing up my list of directories in the =org-agenda-files=
variable.  I just add and remove directories manually here.  Changing
the list of directories in =org-agenda-files= happens very rarely
since new files in existing directories are automatically picked up.

*** Tasks, States, Todo fun

First we define the global todo keywords.
#+BEGIN_SRC emacs-lisp
(setq org-todo-keywords
      (quote ((sequence "TODO(t)" "NEXT(n)" "|" "DONE(d@/!)")
              (sequence "WAITING(w@/!)" "HOLD(h@/!)" "DELEGATED(g@/!)" "|" "CANCELLED(c@/!)" "PHONE"))))

(setq org-todo-keyword-faces
      (quote (("TODO" :foreground "red" :weight bold)
              ("NEXT" :foreground "light blue" :weight bold)
              ("DONE" :foreground "forest green" :weight bold)
              ("WAITING" :foreground "orange" :weight bold)
              ("HOLD" :foreground "orange" :weight bold)
              ("DELEGATED" :foreground "yellow" :weight bold)
              ("CANCELLED" :foreground "dark green" :weight bold)
              ("PHONE" :foreground "dark green" :weight bold))))
#+END_SRC

**** Fast Todo Selection
Fast todo selection allows changing from any task todo state to any
other state directly by selecting the appropriate key from the fast
todo selection key menu.
#+BEGIN_SRC emacs-lisp
(setq org-use-fast-todo-selection t)
#+END_SRC
Changing a task state is done with =C-c C-t KEY=

where =KEY= is the appropriate fast todo state selection key as defined in =org-todo-keywords=.

The setting
#+BEGIN_SRC emacs-lisp
(setq org-treat-S-cursor-todo-selection-as-state-change nil)
#+END_SRC
allows changing todo states with S-left and S-right skipping all of
the normal processing when entering or leaving a todo state.  This
cycles through the todo states but skips setting timestamps and
entering notes which is very convenient when all you want to do is fix
up the status of an entry.

**** Todo State Triggers
I have a few triggers that automatically assign tags to tasks based on
state changes.  If a task moves to =CANCELLED= state then it gets a
=CANCELLED= tag.  Moving a =CANCELLED= task back to =TODO= removes the
=CANCELLED= tag.  These are used for filtering tasks in agenda views
which I'll talk about later.

The triggers break down to the following rules:

- Moving a task to =CANCELLED= adds a =CANCELLED= tag
- Moving a task to =WAITING= adds a =WAITING= tag
- Moving a task to =HOLD= adds a =WAITING= tag
- Moving a task to a done state removes a =WAITING= tag
- Moving a task to =TODO= removes =WAITING= and =CANCELLED= tags
- Moving a task to =NEXT= removes a =WAITING= tag
- Moving a task to =DONE= removes =WAITING= and =CANCELLED= tags

The tags are used to filter tasks in the agenda views conveniently.
#+BEGIN_SRC emacs-lisp
(setq org-todo-state-tags-triggers
      (quote (("CANCELLED" ("CANCELLED" . t))
              ("WAITING" ("WAITING" . t))
              ("HOLD" ("WAITING" . t) ("HOLD" . t))
              (done ("WAITING") ("HOLD"))
              ("TODO" ("WAITING") ("CANCELLED") ("HOLD"))
              ("NEXT" ("WAITING") ("CANCELLED") ("HOLD"))
              ("DONE" ("WAITING") ("CANCELLED") ("HOLD")))))

Capture mode now handles automatically clocking in and out of a
capture task.  This all works out of the box now without special hooks.
When I start a capture mode task the task is clocked in as specified
by =:clock-in t= and when the task is filed with =C-c C-c= the clock
resumes on the original clocking task.

The quick clocking in and out of capture mode tasks (often it takes
less than a minute to capture some new task details) can leave
empty clock drawers in my tasks which aren't really useful.
The following prevents this.

**** Setting a default clock task
Per default the =** Organization= task in my tasks.org file receives
misc clock time. This is the task I clock in on when I punch in at the
start of my work day with =F9-I=.  Punching-in anywhere clocks in this
Organization task as the default task.

If I want to change the default clocking task I just visit the
new task in any org buffer and clock it in with =C-u C-u C-c C-x
C-i=.  Now this new task that collects miscellaneous clock
minutes when the clock would normally stop.

You can quickly clock in the default clocking task with =C-u C-c
C-x C-i d=.  Another option is to repeatedly clock out so the
clock moves up the project tree until you clock out the
top-level task and the clock moves to the default task.

*** Publishing and exporting


Org-mode can export to a variety of publishing formats including (but not limited to)

- ASCII
  (plain text - but not the original org-mode file)
- HTML
- LaTeX
- Docbook
  which enables getting to lots of other formats like ODF, XML, etc
- PDF
  via LaTeX or Docbook
- iCal

A new exporter created by Nicolas Goaziou was introduced in org 8.0.

*** Prevent editing invisible text
The following setting prevents accidentally editing hidden text when

the body of a heading and globally fold the org-file with =S-TAB=

I find invisible edits (and undo's) hard to deal with so now I can't

I find extra blank lines in lists and headings a bit of a nuisance.
To get a body after a list you need to include a blank line between
the list entry and the body -- and indent the body appropriately.
Most of my lists have no body detail so I like the look of collapsed
lists with no blank lines better.

The following setting prevents creating blank lines before headings
but allows list items to adapt to existing blank lines around the items:

The following displays the contents of code blocks in Org-mode files
using the major-mode of the code.  It also changes the behavior of
=TAB= to as if it were used in the appropriate major mode.  This means
that reading and editing code form inside of your Org-mode files is
much more like reading and editing of code using its major mode.

** undo-tree
[2013-04-21 So 11:07]
Emacs undo is pretty powerful - but can also be confusing. There are
tons of modes available to change it, even downgrade it to the very
crappy ways one usually knows from other systems which lose
information. undo-tree is different - it helps keeping you sane while
keeping the full power of emacs undo/redo.

** volatile highlights
[2013-04-21 So 20:31]
VolatileHighlights highlights changes to the buffer caused by commands
such as ‘undo’, ‘yank’/’yank-pop’, etc. The highlight disappears at the
next command. The highlighting gives useful visual feedback for what
your operation actually changed in the buffer.

** winner mode - undo and redo window configuration
[2015-02-24 Tue 23:11]
=winner-mode= lets you use =C-c <left>= and =C-c <right>= to switch between
window configurations. This is handy when something has popped up a
buffer that you want to look at briefly before returning to whatever
you were working on. When you're done, press =C-c <left>=.
