[back to package description]language-lua - Lua 5.3 lexer, parser and pretty-printer
This package is just like any other language x packages. It provides lexer, parser and pretty-printer for Lua programming language.
Usage
This module provides 3 parsers.
chunk: Lua file parser.exp: Lua expression parser.stat: Lua statement parser.
Lexing is needed before running a parser. parseText function runs lexer before parsing. So if you want to parse a Lua expression, you can call parseText exp string, where string is the Lua expression to parse.
parseFile is a helper to parse Lua files. Example: parseFile "/path/to/lua/file". This is same as parseText chunk `fmap` readFile path.
Note that parseText may result with failure, so it's return type is Either ParserError a.
Lexer
Lexer is not exported by top-level Language.Lua module. You need to import Language.Lua.Lexer. After that, llex string scans the string and returns token list. Tokens are defined in Language.Lua.Token.
Pretty-printer
Pretty-printer is still under development, and subject to lots of changes. It works, but lots of functionality will be added.
For now, you can use pprint syntax_tree to pretty-print a Lua syntax tree.
