Bitwise Operators

[Guest MikeGooder]

Hi All

Are there any bitwise operators in LUA, there seem to be few variants on the web, but I cannot find any that work on the HC2

its a "bitwise and" I really need.

Cheers

Hi Mike,

Did you find a solution for bitwise operations?

I need bitwise AND, OR and NOT.

According to LUA docs, there are several implementations but none of them work in HC2 (v3.5.9.0). The script just terminates without any message.

I needed to XOR some stuff and had the same issues.  I found some solutions at

which I've expanded.

I've created functions called bitwise_xor and bitwise_xor_8bits_manyargs which you could use to write equivalent AND or OR functions.  An example of usage might be:

I did notice, however, that functions need to be put at the top of an HC2 file in order to use them lower down.  I also discovered by doing fibaro:debug(tostring(_VERSION)) that HC2 claims to use Lua 5.1.

 

Hope this helps.
