How to use other third-Party Modules?

MintXeido

Im curious if i can use other Lua modules that are not installed in the LuaRT.

Samir

Yes you can use any Lua binary module compiled towards Lua 5.4

MintXeido

Great! If im sure, in order to use the third-Party module i have to install it to the same folder where to project is located or i have to install the module somewhere in the LuaRT’s Folder?

Samir

You can put the DLL module in the same folder than your script but it's better to put it in the modules folder for LuaRT installation, in a subfolder with the same name.

For example, for the lfs.dll binary module, put it in modules\lfs\lfs.dll

This way you will be able to require for it from anywhere and rtc will find it when compiling to exe to embed lfs.dll

Amazing! Thank you, i really appreciate your help! 😄

You're welcome 👍🏻

ruby

maybe the most easy way to use third binary module, is to copy existed dlls from LuaRT-Studio to luart/bin folder

test lfs:

copy LuaRT-Studio\bin\clibs54\lfs.dll luaRT/bin

Yes LuaRT Studio comes with some precompiled Lua 5.4 libraries in bin\clibs54 subfolder.

The QuickRT error comes to the fact that the lfs.dir() function returns a "directory metatable" object that cannot be pretty printed. This will be fixed in next release.
