Better file system support

[4x8Matrix]

Is there plans to add FileSystem support into LuaU?

I believe Lua 5.x had io which provided a library to which we can manipulate the state of files, i'm just not sure if there's plans to add something like the sort back in.

That said, is there also any plans to add better filesystem for Require ? If you require a module, you need to specify the full path to that module, this can be pretty problematic when trying to pull in dependencies which have their own LuaU files as the paths would be broken

---

-- Code.luau

require("Folder/Subfolder/Module") -- This is how you would access `Module` at the moment
require("Subfolder/Module") -- This should be how we access `Module`

-- Module.luau

require("Folder/Subfolder2/FileData") -- This is how you would access `FileData` at the moment
require("../Subfolder2/FileData") -- This is ideally what we should do to access `FileData`

Agree, would be pretty helpful to have some sort of a relative file import system.

EDIT: Just found #337 & https://github.com/Roblox/luau/blob/bsharp-rfc-libraries/rfcs/libraries.md#relative.

If you use Luau in your own software, you can try using original liolib.c from Lua 5.1 with a few changes like adding missing defines/functions:

#define LUA_FILEHANDLE		"FILE*"
#define LUA_NUMBER_SCAN		"%lf"
#define LUA_NUMBER_FMT		"%.14g"
#define LUAL_BUFFERSIZE		BUFSIZ
#define LUA_IOLIBNAME	"io"

#define lua_popen(L,c,m)	((void)L, _popen(c,m))
#define lua_pclose(L,file)	((void)L, (_pclose(file) != -1))

#define luaL_optlong(L,n,d)	((long)luaL_optinteger(L, (n), (d)))

and by changing code around luaL_addsize.

But we do have plans to add built-in 'liolib.c' in the future.

Hello! Thanks for the reply ~ sorry my post didn't make the upmost sense, however I do have a follow up question;

Is there plans to add support for our own C Modules?

My next solution was an attempt to write my own C Module or pull in a C Module to handle file system support, but after briefly reading the source for require - i'm not entirely sure if there is support for these modules anymore

The loadlib.cpp file in my repo implements require(it's a copy pasta from PUC Rio lua). It is Intended for use for luau embedders. If ever you want the io module available in lua it's the liolib.cpp
