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 Analysis
A tool for building a scanner that reads source code and breaks it into tokens; the basic building blocks of programs such as keywords, variable names, and operators. The token stream is often passed to a parser, serving as the initial stage of source code processing by a compiler. This lexer also provides Flex compatibility with enhanced support for Unicode characters.
Parser Generators
Automatically generates a parser from a formal grammar specification of a programming language. It transforms token sequences into a structured syntax tree, enabling the construction of compilers and interpreters. This parser also provides compatibility with Bison for seamless integration with standard lexical analysis tools.
