## プロジェクトの歴史と使われ方

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.

### プロジェクトの歴史

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.

### 採用の歴史

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.

### 使われ方

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.

### パッケージ好きにとっての重要性

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.

### タイムライン

- 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.
