rslua

Yet another Lua lexer and Lua parser for Lua 5.3.

Lexer

• input str
• output Result, LexError>

rust use rslua::lexer::Lexer; let mut lexer = Lexer::new(); let tokens = lexer.run(input_lua_code)?;

Parser

• input Vec\
• output Result

rust let mut parser = Parser::new(); let block = parser.run(tokens)?;

AST walker

Use ast_walker to travel the AST, implement the ast_visitor trait to run custom logic.

A complete example

Read lua/json.lua , parse it, walk the AST and generate formatted lua code to json_output.lua.
