Documentation

newtype State Source #

An opaque structure that points to a thread and indirectly (through the thread) to the whole state of a Lua interpreter. The Lua library is fully reentrant: it has no global variables. All information about a state is accessible through this structure.

Synonym for lua_State *. See lua_State.

Constructors

State (Ptr ())

type Reader = FunPtr (State -> Ptr () -> Ptr CSize -> IO (Ptr CChar)) Source #

The reader function used by load. Every time it needs another piece of the chunk, lua_load calls the reader, passing along its data parameter. The reader must return a pointer to a block of memory with a new piece of the chunk and set size to the block size. The block must exist until the reader function is called again. To signal the end of the chunk, the reader must return NULL or set size to zero. The reader function may return pieces of any size greater than zero.

See lua_Reader.

fromType :: Type -> TypeCode Source #

Convert a lua Type to a type code which can be passed to the C API.

toType :: TypeCode -> Type Source #

Convert numerical code to lua type.

type CFunction = FunPtr (State -> IO NumResults) Source #

Type for C functions.

In order to communicate properly with Lua, a C function must use the following protocol, which defines the way parameters and results are passed: a C function receives its arguments from Lua in its stack in direct order (the first argument is pushed first). So, when the function starts, gettop returns the number of arguments received by the function. The first argument (if any) is at index 1 and its last argument is at index gettop. To return values to Lua, a C function just pushes them onto the stack, in direct order (the first result is pushed first), and returns the number of results. Any other value in the stack below the results will be properly discarded by Lua. Like a Lua function, a C function called by Lua can also return many results.

See lua_CFunction.
