软件包摘要
LALR(1) parser generator like yacc or bison
历史
项目历史与用法
Lemon is an LALR(1) parser generator in the SQLite orbit: a yacc-like tool for generating C parsers, but with a deliberately different grammar format and a reentrant, thread-safe parser model.
项目历史
The project is documented by Hwaci and SQLite as a small code-generation utility rather than a standalone source repository. 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.
采用历史
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.
使用方式
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.
为什么软件包爱好者会关心
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.
时间线
- 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.
