regular grammar

Regular grammar is a type of formal grammar used to define simple patterns and languages, often for programming and text processing. It consists of rules that specify how strings (sequences of symbols) can be generated, usually involving a structured approach to how characters are combined. These rules are limited to straightforward patterns, such as matching a specific sequence or a repetitive structure, making them easy to analyze and implement. Regular grammars are fundamental in designing lexical analyzers and defining regular expressions, serving as the basis for many text and pattern matching tools.
