This repository tries to provide some advanced tricks with Torch7 explained easily
LuaJIT FFI library provides an incredible easy way to call external C functions and use C data structures from pure Lua code.
The FFI series will provide several working examples of playing with C from within Torch, taking for granted no prior knowledge of building .so libraries, using Makefile or tackling Tensors pointers.
If you found yourself using several print() and io.read() around the code with the purpose of finding out what's going on, well… there's a better and more efficient way: using a debugger.
There are few alternatives, but we'll start with the easiest one: a command-line debugger.
