WebAug 1, 2024 · The syntax of ANTLR's rules is based on the Extended Backus-Naur Form, or EBNF. The following discussion introduces the EBNF and then presents the different features in parser rules and lexer rules. 3.1 The Extended Backus-Naur Form (EBNF) In the 1950s, researchers looked for ways to describe the syntax of programming languages. WebANTLR supports EBNF, which makes easier to describe most languages ; Features of Lexing Algorithms. flex supports regular expressions to define rules, which works for most elements, but adds complexity; ANTLR supports context-free expression to define rules, which simplifies defining some common elements ;
