Translational Backus–Naur Form
Translational Backus–Naur Form (TBNF or Translational BNF) refers to Backus–Naur form, which is a formal grammar notation used to define the syntax of computer languages, such as Algol, Ada (programming language), Ada, C++, COBOL, Fortran, Java (language), Java, Perl (language), Perl, Python (language), Python, and many others. TBNF goes beyond BNF and Extended Backus–Naur form, extended BNF (EBNF) grammar notation because it not only defines the syntax of a language, but also defines the structure of the abstract syntax tree (AST) to be created in memory and the output intermediate code to be generated. Thus TBNF defines the complete translation process from input source code to intermediate code. Specification of the output intermediate code is optional, in which case you will still get automatic AST creation and have the ability to define its structure in the grammar. Overview The TBNF concept was first published in April 2006 in a paper at SIGPLAN Notices, a special int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backus–Naur Form
In computer science, Backus–Naur form (BNF, pronounced ), also known as Backus normal form, is a notation system for defining the Syntax (programming languages), syntax of Programming language, programming languages and other Formal language, formal languages, developed by John Backus and Peter Naur. It is a metasyntax for Context-free grammar, context-free grammars, providing a precise way to outline the rules of a language's structure. It has been widely used in official specifications, manuals, and textbooks on programming language theory, as well as to describe Document format, document formats, Instruction set, instruction sets, and Communication protocol, communication protocols. Over time, variations such as extended Backus–Naur form (EBNF) and augmented Backus–Naur form (ABNF) have emerged, building on the original framework with added features. Structure BNF specifications outline how symbols are combined to form syntactically valid sequences. Each BNF consists of t ...
