rslua
Yet another Lua lexer and Lua parser for Lua 5.3 written in pure Rust.
Lexer
- input str
- output Result<&Vec<Token>, LexError>
use rslua::lexer::Lexer;
let mut lexer = Lexer::new();
let tokens = lexer.run(input_lua_code)?;
Lexer Config
| Key | Type | Default | Descripten |
|---|---|---|---|
use_origin_string |
bool | false | Use origin string as token value instead of escaped one. |
reserve_comments |
bool | false | Reserve comments as tokens. |
Parser
- input &Vec<Token>
- output Result<Block, SyntaxError>
let mut parser = Parser::new();
let block = parser.run(tokens)?;
AST walker
Use ast_walker to travel the AST, implement the AstVisitor trait to run custom logic.
A complete example
Read Lua source files from ./lua folder, parse them, generate ASTs and walk them through, use a LuaWritter struct which impletements the AstVisitor trait to re-generate formatted Lua source again to ./tmp folder.
