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 Lexer;
let mut lexer = new;
let tokens = lexer.run?;
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 = new;
let block = parser.run?;
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.
