======Emacs======

=====Set up custom lisp path=====
<code lisp>
(add-to-list 'load-path "~/.emacs.d/lisp/")
</code>

=====Show trailing whitespace=====
Show trailing whitespace as red blocks:
<code lisp>
(custom-set-variables
 '(show-trailing-whitespace t)
)
</code>

=====Use Allman/BSD style=====
Make curly braces placement as described by [[https://en.wikipedia.org/wiki/Indent_style#Allman_style|Allman from the BSD project]]:
<code lisp>
(setq c-default-style "bsd" c-basic-offset 4)
</code>

=====Use SmartTabs=====
Use [[http://www.emacswiki.org/emacs/SmartTabs|"SmartTabs"]], ie. tabs for indentation and spaces for alignment.

Create the folder ~/.emacs.d/lisp and download [[https://raw.githubusercontent.com/jcsalomon/smarttabs/master/smart-tabs-mode.el|smart-tabs-mode.el]] and [[https://elpa.gnu.org/packages/cl-lib.html|cl-lib]] into it.

Add the following lines to the ''.emacs'' file:
<code lisp>
(require 'smart-tabs-mode)

(autoload 'smart-tabs-mode "Intelligently indent with tabs, align with spaces!")
(autoload 'smart-tabs-mode-enable "smart-tabs-mode")
(autoload 'smart-tabs-advice "smart-tabs-mode")
(autoload 'smart-tabs-insinuate "smart-tabs-mode")

(smart-tabs-insinuate 'c 'c++ 'java 'javascript 'cperl 'ruby 'nxml)
</code>
=====Switch between cc/h files=====
Switch between the header and implementation using Alt-o.

Download [[http://www.emacswiki.org/emacs/SwitchFile|SwitchFile.el]] to the ~/emacs.d/lisp folder.
<code lisp>
(require 'switch-file)
(global-set-key (kbd "M-o") 'switch-cc-to-h)
</code>

=====Show whitespace=====
Download [[http://emacswiki.org/emacs/WhiteSpace|whitespace.el]] into the ~/.emacs.d/lisp folder.

Use it whenever in c++ mode:
<code lisp>
(require 'whitespace)
(add-hook 'c++-mode-hook 'whitespace-mode)
</code>

Use sane colors:
<code lisp>
(set-face-attribute 'whitespace-space nil :background nil :foreground "LightCyan2")
(set-face-attribute 'whitespace-space-after-tab nil :background nil :foreground "LightCyan2")
(set-face-attribute 'whitespace-tab nil :background nil :foreground "LightCyan2")
(set-face-attribute 'whitespace-line nil :foreground nil :background nil :weight 'bold)
</code>

Disable newlines and wierd rendering of long lines:
<code lisp>
(custom-set-variables
 '(whitespace-style (quote (face tabs spaces trailing space-before-tab indentation empty space-after-tab space-mark tab-mark))
)
