Lexical Analysis and Parsing
Lexers and parsers work together as essential components in the front-end of a compiler or interpreter. The lexer builds a scanner that analyzes raw source code to produce a stream of tokens, while the parser generator creates functions that organize these tokens into a tree structure based on a formal grammar.
Lexical Scanner Utility
A utility for constructing lexical analyzers (scanners) that read source code and break it into meaningful tokens—such as keywords, identifiers, and operators. This serves as the first phase of source code processing in a compiler, providing structured input for the parser. Compatible with Flex syntax, this utility also includes enhanced support for Unicode characters.
Parser Generator Utility
A utility that automatically generates a parser from a formal grammar specification of a programming language. It converts token sequences into structured syntax trees, serving as a foundation for building compilers, interpreters, and other language-processing tools. Compatible with Bison syntax, this utility integrates with standard lexical analyzers.
