Indentation style

In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code that is generally intended to convey structure.

For a general discussion of indentation, see Indentation (typesetting).

Generally, an indentation style uses the same width of whitespace (indentation size) before each line of a group of code so that they appear to be related.

As whitespace consists of both space and tab characters, a programmer can choose which to use – often entering them via the space key or tab key on the keyboard.

Some research has been conducted on the value of code indentation.
