can I get the the .lua files that comes with luasockets somewhere? Like ftp.lua , http.lua etc...
I have no idea how to build something I trying a lot with VStudio but no luck. I tried to look how to build but I didnt understood, did I need lua? luarocks? installed in my pc?
If I had that .lua files it would be ok for my problem
Although it wasn't clearly specified, you're on Win.
Also "can I get the the .lua files that comes with luasockets" doesn't make much sense, because if you already have LuaSocket, then you have the (required .lua) files as well (as they are part of the package).
Anyway, I have built the packages for Win and they can be downloaded from [GitHub]: CristiFati/Prebuilt-Binaries - (master) Prebuilt-Binaries/LuaSocket. The .zip archives are self contained (meaning they are ready to run), check the mentions about compatible Lua versions (you'll most likely have to download and unpack them on your PC, then install LuaSocket on top).
You'll also find there the official repository where I've downloaded the sources from.
Although the real thing happens inside the .dll (codewise in the .c files), you'll probably find some useful stuff in the .lua (wrapper) files as well.
