The '''GNU Coding Standards''' document the [[programming style]] used by the [[GNU Project]]. Its main purpose is to guide all volunteers in writing portable, robust, and reliable programs; and to provide [[GNU]] tools that behave consistently.

The GNU coding standards only mention coding in one language, C.

== Indentation ==

Here is one example of the indentation:

int main()

{

foo(bar);

}

The basic level of indentation puts the curly brackets on one line, indenting them two spaces in. The statement(s) after the brackets are indented four spaces in.

== Variable Declaration ==

Variables are declared each on one line, or two of the same sort on one line. The former is prefered in the GNU coding style.

Example:

int foo;

int bar;

OR

int foo, bar;

The method:

int foo,

bar;

is not permitted under the guidlines.

== Files (Temporary, Configuration and/or Backups) ==

The GNU coding standard tells where to save your temporary, configuration or backup files. It recommends to not assume that /etc or /usr are writeable. A program should have the ability to keep files somewhere else.

== Portability ==

In GNU Emacs, the default style of C source code is GNU.
