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 = " <source code here> ";

let tokenizer = Tokenizer::new(source);
// tokenizer itself is a lazy iterator.
for token in tokenizer {
    match token {
        Ok(token) => {
            // do something with token
        }
        Err(e) => {
            print!("Tokenize Error: {}", e);
        }
    }
}
