How to use lua's load function

[sucrecacao]

Hi,

How can I use lua's load function in moonscript ?
And does it work with a moonscript string only with lua string?

I have found related issue on this topic but it didn't help me solve the problem, maybe their meant to work with older moonscript version.

load only works with Lua strings. If you want to load MoonScript strings, you have to use MoonScript's own function.

moonscript = require "moonscript.base"
lua_code   = moonscript.load "code!"

It's all detailed in the reference manual.

This doesn't work:
I got the following error:

lua: main.lua:1: module 'moonscript.base' not found:
        no field package.preload['moonscript.base']
        no file '/usr/local/share/lua/5.3/moonscript/base.lua'
        no file '/usr/local/share/lua/5.3/moonscript/base/init.lua'

stack traceback:
        [C]: in function 'require'
        main.lua:1: in main chunk
        [C]: in ?

But I installed moonscript through lua rocks and the library is located in:

~/.luarocks/share/lua/5.1/moonscript/base.lua

is there a way to solve this issue in a "clean" way? ( without messing with symlink)

According to https://stackoverflow.com/a/47267672/1517394 you might need to add eval $(luarocks path --bin) to your bashrc.

Ok I have advanced one step, I still get:

Built main.moon

Apparently lua has change the lua_tointeger function from 5.1 to 5.2, this might be the causes of the bug.
I have upgraded from lua5.1 to lua5.3, but I still have the error message.

Ok I have solved the issue using lua5.1 instead of lua which was using version 5.3

Does moon-script only work with 5.1?

[sucrecacao]

I also had to use loadstring instead of load ( moonscript.loadstring)

Also to use lua load I had to use the old loadstring, so I guess my moonscript is just installed on 5.1 but most of the doc and issue are for 5.3
