== Style ==
 
Any mode based on {{ModeLink|cc-mode}} provides automatic indentation. The default style is <code>gnu</code>. It is the one recommended by the Free Software Foundation for GNU projects but you can use a different one.
 
 
 
Here is a basic list of predefined styles:
 
; <code>gnu</code>
 
: The default style for GNU projects
 
; <code>k&r</code>
 
: What Kernighan and Ritchie, the authors of C used in their book
 
; <code>bsd</code>
 
: What BSD developers use, aka “Allman style” after Eric Allman.
 
; <code>whitesmith</code>
 
: Popularized by the examples that came with Whitesmiths C, an early commercial C compiler.
 
; <code>stroustrup</code>
 
: What Stroustrup, the author of C++ used in his book
 
; <code>ellemtel</code>
 
: Popular C++ coding standards as defined by “Programming in C++, Rules and Recommendations,” Erik Nyquist and Mats Henricson, Ellemtel
 
; <code>linux</code>
 
: What the Linux developers use for kernel development
 
; <code>python</code>
 
: What Python developers use for extension modules
 
; <code>java</code>
 
: The default style for java-mode (see below)
 
; <code>user</code>
 
: When you want to define your own style
 
 
 
You can look the [http://cc-mode.sourceforge.net/html-manual/Built_002din-Styles.html#Built_002din-Styles cc-mode documentation] for a complete list of builtin style.
 
For visual example of each style you can look the [http://en.wikipedia.org/wiki/Indent_style Wikipedia article on indenting style].
 
 
 
* The default style is set via the variable {{Variable|c-default-style}}
 
* Use {{CommandKeys|C-c .|c-set-style}} to change the indentation style of the current buffer.
 
* The amount of space use to indent is set via the variable {{Variable|c-basic-offset}}.
 
 
 
To set the default style to K&R and use 4 spaces, add this to your {{EmacsConfigFile}}:
 
 
 
<source lang="lisp">
 
; set k&r style
 
(setq c-default-style "k&r")
 
; indent with 4 spaces
 
(setq c-basic-offset 4)
 
</source>
