how to install luarocks on windows in 2020 :(

ugh.md

1. get python (lol). make sure you check the box that says "add python to PATH", this will be important later

https://www.python.org/

2. get a visual studio compiler. make sure to select either desktop development with C++ or, game dev with C++, or both~

https://visualstudio.microsoft.com/downloads/

3. open a native tools command prompt: select x64 native tools command prompt for VS2019 from the start menu

4. install and run hererocks

pip install git+https://github.com/luarocks/hererocks
hererocks --luajit 2.1.0-beta3 -r latest <the new folder you want to install lua at>

5. go to start menu and type in "Edit environment variables for your account". from this screen, edit your Path variable to include

<lua folder>/bin

6. close your native tools command prompt and reopen it

7. try the lua and luarocks commands to see if they work.

8. as of 10/31/2020, the luarocks install might be broken! see luarocks/luarocks#1232 if so, open up <lua folder>\bin\luarocks.bat, you should see something like

@ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION ENABLEEXTENSIONS
 >NUL
SET "LUA_PATH=E:\lua\luarocks\lua\?.lua;E:\lua\luarocks\lua\?\init.lua;%LUA_PATH%"

that >NUL is not supposed to be there, let's just manually remove it:

@ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION ENABLEEXTENSIONS
SET "LUA_PATH=E:\lua\luarocks\lua\?.lua;E:\lua\luarocks\lua\?\init.lua;%LUA_PATH%"

and try again
