How about this workaround (ugly, but still could work): local ffi = require( "ffi" ) ffi.cdef[[ typedef struct vec3 { float x, y, z; } vec3; ]] local a = ffi.new( "vec3[?]", 1024 + 1 ) local b = ffi.

Because wrapping every single FFI data access call has a significant performance hit when working with very large datasets. CR

It's much more complicated than that. Often it's hard to tell what is FFI and what is regular Lua. There is not always a clear separation because usually a combination of FFI and Lua types are used a

2009/11/30 cynthia powers <powcyn@gmail.com>: It all depends on the Lua code you want to preserve. If it uses ipairs only to iterate over arrays, you can override it. However if it uses Even if you d

Unless you have an __index metamethod that interprets the /contents/ of the key that was given (of course, creating syntax sugar in the Language just for cases where you have such a metamethod would

Hello all, The attached archive contains a first version of a module that essentially serves as a bridge between Lua and C arrays by exposing C arrays (of all types) to Lua as tables with suitable in
