SQLite documents Lemon as a set of files kept inside the SQLite source tree, including lemon.c for the generator, lempar.c for the parser template, and lemon.html for detailed documentation. Lemon evolved as a tool shaped by SQLite's own parser needs. SQLite's Lemon page notes that keeping the generator inside the SQLite project allowed the tool to gain SQLite-specific features, such as fallback tokens for SQL keywords and changes aimed at efficient parser generation. ### Historique d'adoption Its most important adoption path is SQLite itself. SQLite uses Lemon to generate the main SQL parser from parse.y, and also uses it for FTS5 query-pattern parsing from fts5parse.y. Outside SQLite, Lemon is attractive to C projects that want a compact parser generator with generated parsers that avoid yacc's global-state style. ### Modes d'utilisation Users write a context-free grammar and run lemon to emit C parser code. Compared with yacc and bison, Lemon uses different grammar syntax, expects the tokenizer to call the parser, and emphasizes reentrant and thread-safe generated parsers. ### Pourquoi les passionnés de paquets s'y intéressent Lemon is a package-nerd favorite because it is a small, old-school build-time tool hidden inside one of the most widely deployed C projects. Installing it as a separate package gives developers access to SQLite's parser generator without vendoring the SQLite source tree. ### Chronologie - 2000s: Lemon became part of the SQLite source tree as the generator for SQLite's SQL parser. - 2022: SQLite's Lemon documentation described Lemon as having no standalone source repository and being maintained as files inside the SQLite tree. ### Related projects - SQLite is the parent project and primary user. - yacc and GNU Bison are the older parser-generator family Lemon is commonly compared with. ### Sources - - ## Notes de sécurité Aucun manifest local de gestion des secrets correspondant n'a été trouvé pour lemon.
