Parsers all the way down: writing a self-hosting parser
Read OriginalThe article details the development of a self-hosting parser for a new systems programming language. It explains the journey from an initial yacc/lex-based parser, used to inform language design and produce a formal grammar, to the creation of a parser written in the language itself—a key milestone in bootstrapping the compiler. The author provides code examples illustrating grammar rules and discusses the role of the lexer in tokenization.
