# rslua
Yet another Lua lexer and Lua parser for Lua 5.3.
## Lexer
- **input** str
- **output** Result<Vec\<Token>, LexError>
```rust
use rslua::lexer::Lexer;
let mut lexer = Lexer::new();
let tokens = lexer.run(input_lua_code)?;
```
## Parser
- **input** Vec\<Token>
- **output** Result<Block, ParseError>
```rust
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, parse them, generate ASTs and walk them through, use a `LuaWritter` struct which impletements the `AstVisitor` trait to re-generate formatted Lua source again.
