2. Extended Backus–Naur form - Wikipedia

   en.wikipedia.org/wiki/Extended_Backus–Naur_form

   Extended Backus–Naur form. In computer science, extended Backus–Naur form (EBNF) is a family of metasyntax notations, any of which can be used to express a context-free grammar. EBNF is used to make a formal description of a formal language such as a computer programming language. They are extensions of the basic Backus–Naur form (BNF ...

3. ANTLR - Wikipedia

   en.wikipedia.org/wiki/ANTLR

   In computer-based language recognition, ANTLR (pronounced antler), or ANother Tool for Language Recognition, is a parser generator that uses a LL (*) algorithm for parsing. ANTLR is the successor to the Purdue Compiler Construction Tool Set (PCCTS), first developed in 1989, and is under active development. Its maintainer is Professor Terence ...

It is currently available in English, Hebrew, Yiddish, and Chinese. MS Word and MS Excel. Their macro languages used to be localized in non-English languages.

5. Syntax-directed translation - Wikipedia

   en.wikipedia.org/wiki/Syntax-directed_translation

   Syntax-directed translation refers to a method of compiler implementation where the source language translation is completely driven by the parser . A common method of syntax-directed translation is translating a string into a sequence of actions by attaching one such action to each rule of a grammar. [1] Thus, parsing a string of the grammar ...

6. Abstract syntax tree - Wikipedia

   en.wikipedia.org/wiki/Abstract_syntax_tree

   Abstract syntax tree. An abstract syntax tree (AST) is a data structure used in computer science to represent the structure of a program or code snippet. It is a tree representation of the abstract syntactic structure of text (often source code) written in a formal language. Each node of the tree denotes a construct occurring in the text.

7. Compiler - Wikipedia

   A program that translates from a low-level language to a higher level one is a decompiler. [63] A program that translates into an object code format that is not supported on the compilation machine is called a cross compiler and is commonly used to prepare code for execution on embedded software applications.
