Bitwise operators in lua.

[Sane]

Hi there,

it seems that the bitwise operators >>, <<, ~ in lua don't work. When using any of them I get syntax errors.

Using BitOp lib works. The following prints "....11".

+ using BitOp lib

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

local bit = require("bit")
local xor = bit.bxor
local x = 4
x = xor(x, 15)
print ("...."..tostring(x))


But require is not allowed when security is on. I've tried to set the mod as trusted, but that still doesn't work.

+ setting security in minetest.conf

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

secure.enable_security = true
secure.trusted_mods = test


• Shouldn't the operators work?
• If forced to use BitOp, maybe it could be referenced by default, so no require is needed and thus no security issues.
• Why does setting test as trusted not allow using require?

using minetest-0.4.12-7a6e4dc (sfan5's build)
on windows.

Steps to reproduce:
o Set ... games\minimal\mods\test\init.lua to the code mentioned above.
o Run any game
o Marvel at syntax error messages or security issues messages.
