First on the standard list of metasyntactic variables used
The terms foobar
, foo, bar, and baz
are sometimes used as placeholder names (also referred to as metasyntactic variables) in computer programming or computer-related documentation. They have been used to name entities such as variables, functions, and commands whose purpose is unimportant and serve only to demonstrate a concept. The words themselves have no meaning in this usage. Foobar
is sometimes used alone; foo, bar, and baz are sometimes used in that order, when multiple entities are needed.
