His last name is the N in the BNF notation ( Backus-Naur form ), used in the description of the syntax for most programming languages.

* A BNF syntax summary of ALGOL 60

In computer science, Augmented Backus – Naur Form ( ABNF ) is a metalanguage based on Backus – Naur Form ( BNF ), but consisting of its own syntax and derivation rules.

In computer science, BNF ( Backus Normal Form or Backus – Naur Form ) is one of the two main notation techniques for context-free grammars, often used to describe the syntax of languages used in computing, such as computer programming languages, document formats, instruction sets and communication protocol ; the other main technique for writing context-free grammars is the van Wijngaarden form.

BNF's syntax itself may be represented with a BNF like the following:

In the ALGOL 58 report, John Backus presented a formal notation for describing programming language syntax ( later named Backus Normal Form then renamed Backus-Naur Form ( BNF )).

RFC 2141 ( dated May 1997 and still classified as requests discussion and suggestions for improvements ) describe in BNF the syntax of URNs as:

Some of the widely used formal metalanguages for computer languages are Backus – Naur Form ( BNF ), Extended Backus – Naur Form ( EBNF ), Wirth syntax notation ( WSN ), and Augmented Backus – Naur Form ( ABNF ).

The abstract syntax for the π-calculus is built from the following BNF grammar ( where x and y are any names from Χ ):

The BNF for a much simplified CL command syntax would be defined as follows:

Includes entire syntax of PL / M in BNF notation.

Basically, the syntax statement is an augmented BNF production with associated semantics added on the right:

* a mathematically exact notation, Backus-Naur Form ( BNF ), was used to describe the language's syntax.

Nearly all subsequent programming languages have used a variant of BNF to describe the context-free portion of their syntax.

The syntax of the compiler's input language ( in this case, XPL ) is described by a BNF grammar.

The BNF ( Backus – Naur Form ) syntax definition of PDDL3. 1 can be found among the resources of the IPC-2011 homepage.

Here is the BNF for Algol60 and the ICL2900 compiler source, library documentation, and a considerable test suite including Brian Wichmann's tests.

In computer science, a popular notation for context-free grammars is Backus – Naur Form, or BNF.

Biological nitrogen fixation ( BNF ) occurs when atmospheric nitrogen is converted to ammonia by an enzyme called nitrogenase.

The reaction for BNF is:

* BNF, is a metasyntax used to express context-free grammar: that is, a formal way to describe formal languages.

* Belarusian ( National ) People's Front " Revival ", better known as the BPF, a political party created in Belarus during the perestroika times ( BNF is from the Latin translitteration of the Belarusian Беларускі Народны Фронт " Адраджэньне " ( БНФ ): Biełaruski Narodny Front " Adradžeńnie ")

* BNF is the IATA airport code for the Warm Springs Bay Seaplane Base, Baranof Island, Alaska

However, Donald Knuth argued that BNF should rather be read as Backus – Naur Form, as it is

A BNF specification is a set of derivation rules, written as

Parsing expression grammars build on the BNF and regular expression notations to form an alternative class of formal grammar, which is essentially analytic rather than generative in character.

The earliest and still most common form of compiler-compiler is a parser generator, whose input is a grammar ( usually in BNF ) of a programming language, and whose generated output is the source code of a parser often used as a component of a compiler.

The British National Formulary ( BNF ) is a medical and pharmaceutical reference book that contains a wide spectrum of information and advice on prescribing and pharmacology, along with specific facts and details about all medicines available on the National Health Service ( NHS ), including indication ( s ), contraindications, side effects, doses, legal classification, names and prices of available proprietary and generic formulations, and any other notable points.

The BNF is available as a book, a website and a mobile app.

There are also editions specially for nurses-The Nurse Prescriber's Formulary and The Extended Nurse Prescriber's Formulary, although with the recent changes to allow Extended Nurse Prescribers to prescribe from the full BNF, the fate of the latter publication is in some doubt.

The BNF is divided into various sections with the main sections on drugs and preparations being organised by body system.

Given a set of action names, the set of CCS processes is defined by the following BNF grammar:

Postfix notation makes the language easier to parse and extend ; Forth's flexibility makes a static BNF grammar inappropriate, and it does not have a monolithic compiler.

The language of classical linear logic ( CLL ) is defined inductively by the BNF notation

" It generates a parser ( the part of a compiler that tries to make syntactic sense of the source code ) based on an analytic grammar written in a notation similar to BNF.

* Compiler Description Language, to develop compilers, based on affix grammars, similar to Backus – Naur form ( BNF ) notation.

SRGS specifies two alternate but equivalent syntaxes, one based on XML, and one using Augmented BNF format.

In particular, his role as editor of the influential " Report on the Algorithmic Language ALGOL 60 " with its pioneering use of BNF was recognized.

In June 2012, the National Institute for Health and Clinical Excellence released applications for offline access to the BNF on iOS and Android devices.

Along with his friends Nawaz Khan Naji, Mohammad Rafiq and Shujaat Ali, Khan established BNF on July 30, 1992.
