LuaFileSystem
File System Library for the Lua Programming Language

## Overview

LuaFileSystem is a Lua library developed to complement the set of functions related to file systems offered by the standard Lua distribution.

LuaFileSystem offers a portable way to access the underlying directory structure and file attributes.

LuaFileSystem is free software and uses the same license as Lua 5.x (MIT).

## Status

Current version is 1.8.0. It works with Lua 5.1, 5.2, 5.3 and 5.4, and it runs on various flavors of Unix (including Linux, BSDs, macOS) and Windows.

## Download

LuaFileSystem can be installed using LuaRocks:

    $ luarocks install luafilesystem

Its source can be found at its Github page.
