A simple bit array (or bit set, bit string, boolean vector, ... whatever) data structure for Lua written in pure C.

The data structure Bitarray stores bits (booleans) in an array in a memory-saving manner internally. One can assign value (0 or 1) to each element as well as extract values from the array.

It will install the release version.

luarocks install bitarray

make all LUA_VERSION=5.3 # or 5.1, 5.2

The generated shared library will reside in out folder. Unfortunately, I understand the difficulty of finding the right install path for libraries for different platforms so it is your responsibility to copy the file there. Typically it can be /usr/local/lib/lua/5.3/.

local Bitarray = require'bitarray' local a = Bitarray.new(10) a[1] = true for i = 1, #a do print(a[i]) end -- true false false false false false false false false false
