Added source to the actual repo for the new version of FakeBitOps.
Check that out and quit worrying about getting updates here. If and when I get the module done, it’ll go under that repo.
This used to be in the Garrysmod.org section. But I have moved it here and deleted the content of the old thread and posted the link to this thread there.
Hey guys, I’m hacking together some stuff that requires bitwise operations, so I made a pure lua library for dealing with binary and hex data. It’s emulated binary operations, so all of it is done through string manipulation.
I’ve lurked here for awhile and figured it could be useful to some of you, so I’m posting it here.
License is BSD. I’d be happy if some of you could contribute. Just ask to join the google code and I’ll accept. Even if you’re just going in there to clean or document.
Hope you find it useful.
Almost the entire library is documented here:
Binary Operations Available:
Zero Padding Left
Zero Padding Right
Left Rotate With Carry Over
Right Rotate With Carry Over
Left Rotate Without Carry Over
Right Rotate Without Carry Over
Binary to Hex
Hex Operations Available:
Bitwise Zero Padding Left (specify 64 as length and FF will become 00000000000000FF)
Bitwise Zero Padding Right (specify 64 as length and FF will become FF00000000000000)
Left Bitwise Rotate With Carry Over
Right Bitwise Rotate With Carry Over
Left Bitwise Rotate Without Carry Over
Right Bitwise Rotate Without Carry Over
Hex to Binary
Number Operations Available:
Number to hex
Number to binary
String Operations Available:
String to binary
String to hex
There is zero error handling at the moment, so try and keep your string lengths divisible by 8 for binary, divisible by 2 for hex.
Let me know what you think or if you want to join up.
