Kernel normal form, or KNF, is the coding style used in the development of code for the BSD operating systems. Based on the original KNF concept from the Computer Systems Research Group, it dictates a programming style to which contributed code should adhere prior to its inclusion into the codebase. KNF started out as a codification of how Ken Thompson and Dennis Ritchie formatted the original UNIX C source code. It describes such things as how to name variables, use indents and the use of ANSI C or K&R C code styles. Each BSD variant has its own KNF rules, which have evolved over time to differ from each other in small ways.
Famous quotes containing the words kernel, normal and/or form:
“All true histories contain instruction; though, in some, the treasure may be hard to find, and when found, so trivial in quantity that the dry, shrivelled kernel scarcely compensates for the trouble of cracking the nut.”
—Anne Brontë (1820–1849)
“The normal present connects the past and the future through limitation. Contiguity results, crystallization by means of solidification. There also exists, however, a spiritual present that identifies past and future through dissolution, and this mixture is the element, the atmosphere of the poet.”
—Novalis [Friedrich Von Hardenberg] (1772–1801)
“Modernity exists in the form of a desire to wipe out whatever came earlier, in the hope of reaching at least a point that could be called a true present, a point of origin that marks a new departure.”
—Paul De Man (1919–1983)
