lua_rust

lua syntax parser in Rust

• Greatly in progress
• LALR(1), GLR parser
• syntax referenced from lua 5.4 reference manual

project structure

• tokenizer: tokenizing lua code string
• parser: parsing tokenized lua code into AST
• exec: executable version of the parser

Cargo Features

• 32bit: use 32bit integer and float for lua numeric type
• diag: enable to_diag() function for ParseError

how to run

$ cargo run <source_file.lua>

will print the pretty-formatted Debug output of the AST ( "{:#?}" )

lib.rs:

let source = " <lua source code> ";

let block = match lua_parser::parse_str(&source) {
    Ok(block) => block,
    Err(err) => {
        println!("{}", err);
        return;
    }
};

println!("AST:\n{:#?}", block);
