  I need a function to know what computer emacs is running on. The display width of 1152 pixel is an oddity of hyper-v and for my usecase specific enough to tell the machine.

#+BEGIN_SRC emacs-lisp
  (defvar my/whoami
    (if (string-equal user-login-name "POH")
        "work_remote"
      (if (equal (display-pixel-width) 1152)
          "work_hyperv"
        (if (string-equal system-type "gnu/linux")
        "home"))))

* Stuff to add / to fix
  - smartparens
    a sane default configuration for navigation, manipulation etc. is still necessary
  - Spaceline / Powerline or similar
    I want a pretty status bar!
  - Git gutter:
    Do some configuration to make it useful (see given source link in the [[*Git][Section]] of gutter)
    Maybe only enable it for modes where it is likely I use git?
  - Some webmode stuff
  - markdown:
    add hooks for certain file extensions, maybe add a smart way to start gfm-mode if markdown-file is in a git-project
  - move package dependend configurations inside the package configuration itself, like keymaps for magit

* Update config in a running config
  Two options:
  - reload the open file: M-x load-file, then press twice to accept
    the default filename, which is the currently opened
  - Point at the end of any sexp and press C-x C-e
* Customize default settings
  Keep the .emacs.d clean by moving user files into separate directories.
  - user-local: directory for machine specific files
  - user-global: directory for files which work on any machine
  - the backup and auto-save files go right to /tmp

#+BEGIN_SRC emacs-lisp

  Don't count two spaces after a period as the end of a sentence.
  Just one space is needed
#+BEGIN_SRC emacs-lisp

#+END_SRC

  Delete the region when typing, just like as we expect nowadays.
#+BEGIN_SRC emacs-lisp

* Visuals
** Font

 Don't add the font in the work environment, which I am logged in as POH

#+BEGIN_SRC emacs-lisp
 (unless (string-equal my/whoami "work_remote")
   (set-face-attribute 'default nil :font "Hack-12")
 )
#+END_SRC

** Themes
*** Material Theme
 The [[https://github.com/cpaulik/emacs-material-theme][Material Theme]] comes in a dark and a light variant. Not too dark
 to be strenious though.
 b
#+BEGIN_SRC emacs-lisp
 (use-package material-theme
     :if (window-system)
     :defer t
     :ensure t
 )
#+END_SRC
*** Apropospriate Theme
 Variants dark and light

#+BEGIN_SRC emacs-lisp
 (use-package apropospriate-theme
     :if (window-system)
     :defer t
     :ensure t
 )
#+END_SRC

*** Ample Theme
    Variants:
    - ample
    - ample-flat
    - ample-light

#+BEGIN_SRC emacs-lisp
(use-package ample-theme
  :if (window-system)
  :defer t
  :ensure t
  :init
  (load-theme 'ample-flat t)
)
#+END_SRC
** Prettier Line Wraps
   By default there is no line wrapping. M-q actually modifies the buffer, which might not be wanted.
   So: enable visual wrapping and keep indentation if there are any.

#+BEGIN_SRC emacs-lisp
   (global-visual-line-mode)
   (diminish 'visual-line-mode)
   (use-package adaptive-wrap
     :ensure t
     :init
     (when (fboundp 'adaptive-wrap-prefix-mode)
       (defun my-activate-adaptive-wrap-prefix-mode ()
         "Toggle `visual-line-mode' and `adaptive-wrap-prefix-mode' simultaneously."
         (adaptive-wrap-prefix-mode (if visual-line-mode 1 -1)))
       (add-hook 'visual-line-mode-hook 'my-activate-adaptive-wrap-prefix-mode))
   )
#+END_SRC

** Mode Line
   Change the default mode line to something prettier. [[https://github.com/Malabarba/smart-mode-line][Source]]

#+BEGIN_SRC emacs-lisp
(use-package smart-mode-line
  :ensure t
  :config
  (tool-bar-mode -1)
  (setq sml/theme 'respectful)
  (setq sml/name-width 40)
  (setq sml/mode-width 'full)
  (set-face-attribute 'mode-line nil
                      :box nil)
  (sml/setup))
#+END_SRC

** Line numbers

#+BEGIN_SRC emacs-lisp
(use-package linum
  :ensure t
  :init
  (add-hook 'prog-mode-hook 'linum-mode))   
#+END_SRC

** Misc
   UTF-8 please
 
#+BEGIN_SRC emacs-lisp
 (setq locale-coding-system 'utf-8)
 (set-terminal-coding-system 'utf-8)
 (set-keyboard-coding-system 'utf-8)
 (set-selection-coding-system 'utf-8)

#+END_SRC

   Turn off blinking cursor
 
#+BEGIN_SRC emacs-lisp
 (blink-cursor-mode -1)
#+END_SRC

#+BEGIN_SRC emacs-lisp
 (show-paren-mode t)
 (column-number-mode t)
 (setq uniquify-buffer-name-style 'forward)
#+END_SRC

   Avoid tabs in place of multiple spaces (they look bad in TeX) and show empty lines

#+BEGIN_SRC emacs-lisp
 (setq-default indent-tabs-mode nil)
 (setq-default indicate-empty-lines t)
#+END_SRC

   Smooth scrolling. Emacs tends to be jumpy, this should change it.

#+BEGIN_SRC emacs-lisp
(setq scroll-margin 5
      scroll-conservatively 10000
      scroll-preserve-screen-position 1
      scroll-step 1)
#+END_SRC

   Highlight current line

#+BEGIN_SRC emacs-lisp
(global-hl-line-mode t)
#+END_SRC

* Usability  
** which-key
   Greatly increases discovery of functions!
   Click [[https://github.com/justbur/emacs-which-key][here]] for source and more info.
   Info in Emacs: M-x customize-group which-key

#+BEGIN_SRC emacs-lisp
   (use-package which-key
       :ensure t
       :diminish which-key-mode
       :config
       (which-key-mode)
       (which-key-setup-side-window-right-bottom)
       (which-key-setup-minibuffer)
       (setq which-key-idle-delay 0.5)
   )
#+END_SRC
** Recentf
   Activate and configure recentf

#+BEGIN_SRC emacs-lisp
   (recentf-mode t)
   (setq recentf-max-saved-items 200)
#+END_SRC
** Hydra
   Hydra allows grouping of commands

#+BEGIN_SRC emacs-lisp
   (use-package hydra
       :ensure t
       :bind
       ("C-c f" . hydra-flycheck/body)
       ("C-c g" . hydra-git-gutter/body)
       :config
       (setq-default hydra-default-hint nil)
   )
#+END_SRC

** Evil
   So... Evil Mode might be worth a try

#+BEGIN_SRC emacs-lisp
   (use-package evil
     :ensure t
     :defer .1 ;; don't block emacs when starting, load evil immediately after startup
     :init
     (setq evil-want-integration nil) ;; required by evil-collection
     :config
     (evil-mode 1)) ;; for now deactivate per default
#+END_SRC

   Evil-collection is a bundle of configs for different modes.
   2018-05-01: evil collection causes error
   "Invalid function: with-helm-buffer"
#+BEGIN_SRC emacs-lisp
   ;(use-package evil-collection
   ;  :after evil
   ;  :ensure t
   ;  :config
   ;  (evil-collection-init))
#+END_SRC

   Evil-goggles give visual hints when editing texts, so it's more obvious what is actually happening. [[https://github.com/edkolev/evil-goggles][Source]]
  
#+BEGIN_SRC emacs-lisp
(use-package evil-goggles
  :after evil
  :ensure t
  :diminish evil-goggles-mode
  :config
  (evil-goggles-mode)
  (evil-goggles-use-diff-faces))
#+END_SRC
** General (keymapper)
   I just use general.el to define keys and keymaps. With it I can set leader keys and create keymaps for them. It also integrates well with which-key.
   [[https://github.com/noctuid/general.el][Source]]

#+BEGIN_SRC emacs-lisp
   (use-package general
     :ensure t
   )
#+END_SRC

** Custom key mappings
   Now some keymaps.
   If there is no map defined, it is considered the global key map.

#+BEGIN_SRC emacs-lisp
   (general-define-key
    :states '(normal visual insert emacs)
    :prefix "SPC"
    :non-normal-prefix "M-SPC"
    "TAB" '(ivy-switch-buffer :which-key "prev buffer")
    "SPC" '(counsel-M-x :which-key "M-x")) 
#+END_SRC

   A map for org-mode
   
#+BEGIN_SRC emacs-lisp
   (general-define-key
    :states '(normal visual insert emacs)
    :keymaps 'org-mode-map
    :prefix "SPC"
    :non-normal-prefix "M-SPC"
    "t" '(counsel-org-tag :which-key "org-tag"))
#+END_SRC
 
** List buffers
   Ibuffer is the improved version of list-buffers.
   Make ibuffer the default buffer lister. [[http://ergoemacs.org/emacs/emacs_buffer_management.html][Source]]
#+BEGIN_SRC emacs-lisp
   (defalias 'list-buffers 'ibuffer)
#+END_SRC

   Also auto refresh dired, but be quiet about it. [[http://whattheemacsd.com/sane-defaults.el-01.html][Source]]
#+BEGIN_SRC emacs-lisp
   (add-hook 'dired-mode-hook 'auto-revert-mode)
   (setq global-auto-revert-non-file-buffers t)
   (setq auto-revert-verbose nil)
#+END_SRC
** ivy / counsel / swiper
   Flx is required for fuzzy-matching
   Is it really necessary?
   BEGIN_SRC emacs-lisp
   (use-package flx)
   end_src

   Ivy displays a window with suggestions for hotkeys and M-x

#+BEGIN_SRC emacs-lisp
   (use-package ivy
       :ensure t
       :diminish
       (ivy-mode . "")                   ;; does not display ivy in the mode line
       :init
       (ivy-mode 1)
       :bind
       ("C-c C-r" . ivy-resume)
       :config
       (setq ivy-use-virtual-buffers t)  ;; recent files and bookmarks in ivy-switch-buffer
       (setq ivy-height 20)              ;; height of ivy window
       (setq ivy-count-format "%d/%d")   ;; current and total number
       (setq ivy-re-builders-alist       ;; regex replaces spaces with *
             '((t . ivy--regex-plus)))
   )
#+END_SRC

   The find-file replacement is nicer to navigate

#+BEGIN_SRC emacs-lisp

** Treemacs
   A file manager comparable to neotree.
   [[https://github.com/Alexander-Miller/treemacs][Github]]

   It has some requirements, which gets used here anyway:
   - ace-window

** Window Handling
   Some tools to easen the navigation, creation and deletion of windows

*** Ace-Window

#+BEGIN_SRC emacs-lisp
    (use-package ace-window
      :ensure t
      :init
      (global-set-key (kbd "C-x o") 'ace-window)
    )
#+END_SRC

*** Windmove
    Windmove easens the navigation between windows.
    Here we are setting the default keybindings (shift+arrow)

    CURRENTLY NOT WORKING, defaults are blocked.
    Also not sure if necessary when using ace-window.
#+BEGIN_SRC emacs-lisp
    (use-package windmove
      :ensure t
      :config
      (windmove-default-keybindings)
    )
#+END_SRC

** misc
   Newline at the end of file

#+BEGIN_SRC emacs-lisp
(setq require-final-newline t)
#+END_SRC

   Delete the selection with a keypress

#+BEGIN_SRC emacs-lisp
(delete-selection-mode t)
#+END_SRC

   Remember the current location in a file

#+BEGIN_SRC emacs-lisp
(use-package saveplace
  :unless noninteractive
  :config
  (save-place-mode))
#+END_SRC

* Org Mode
** Installation
   Although org mode ships with Emacs, the latest version can be installed externally. The configuration here follows the [[http://orgmode.org/elpa.html][Org mode ELPA Installation instructions.]]
   Added a hook to complete org functions, company-capf is necessary for this


#+BEGIN_SRC emacs-lisp
   (use-package org
       :ensure org-plus-contrib
       :init
       (add-hook 'org-mode-hook 'company/org-mode-hook)
   )
#+END_SRC

   To avoid problems executing source blocks out of the box. [[https://emacs.stackexchange.com/a/28604][Others have the same problem, too]]. The solution is to remove the .elc files form the package directory:

#+BEGIN_SRC shell
   var ORG_DIR=(let* ((org-v (cadr (split-string (org-version nil t) "@"))) (len (length org-v))) (substring org-v 1 (- len 2)))
   rm ${ORG_DIR}/*.elc
#+END_SRC

   The default value for the org tag column is -77, which is weird for smaller width windows. I'd rather have the tags align horizontally with the header.

** Org babel/source blocks
   I like to have source blocks properly syntax highlighted and with the editing popup window staying within the same window so all the windows don't jump around. Also, having the top and bottom trailing lines in the block is a waste of space, so we can remove them

   I noticed that fontification doesn't work with markdown mode when the block is indented after editing it in the org src buffer - the leading #s for headers don't get fontified properly because they apppear as Org comments. Setting ~org-src-preserve-identation~ makes things consistent as it doesn't pad source blocks with leading spaces

* Personal Finances
  After trying ledger, I chose beancount. It is closer to real bookkeeping and has stricter rules.
  Since there is no debian package, it is an option to install it via pip.
  I picked /opt for the installation path

#+BEGIN_SRC shell
  sudo su
  cd /opt
  python3 -m venv beancount
  source ./beancount/bin/activate
  pip3 install wheel
  pip3 install beancount
  deactivate
#+END_SRC

  When using beancount, it will automatically pick the created virtual environment.

  Activate the beancount mode. ATTENTION: This mode is made by myself.

#+BEGIN_SRC emacs-lisp

   for python-language-server see here: [[https://github.com/palantir/python-language-server][Link]]

   Automatically start python-mode when opening a .py-file.
   Not sure if python.el is better than python-mode.el.
   See [[https://github.com/jorgenschaefer/elpy/issues/887][here]] for info about ~python-shell-completion-native-enable~.
   The custom function is to run inferiour processes (do I really need that?), see [[https://emacs.stackexchange.com/questions/16361/how-to-automatically-run-inferior-process-when-loading-major-mode][here]].

   Also limit the completion backends to those which make sense in Python.

Jedi is a backend for python autocompletion and needs to be installed on the server:
- pip install jedi
Code checks need to be installed, too:
- pip install flake8

A wrapper to handle virtual environments.
I strongly recommend to install virtual environments on the terminal, not through this wrapper, but changing venvs is fine.

I want Emacs to automatically start the proper virtual environment.
Required is a .python-version file with, content in the first line being /path/to/virtualenv/

   For latex-preview-pane a patch might be necessary (as of 2017-10), see the issue [[https://github.com/jsinglet/latex-preview-pane/issues/37][here]]

* Orchestrate the configuration
  Some settings should be set for all systems, some need to be specific (like my job-emacs doesn't need development tools).

** Common

** Home

** Work
   I mainly only use org
** Work, Hyper-V
   For testing purproses I keep a working emacs in a debian on hyper-v. The demands here are different to the other work-emacs

* Finishing
  Stuff which I want to run in the end
