Modulehslua-aeson-2.3.2Haskell2010
HsLua.Aeson
Pushes and retrieves aeson Values to and from the Lua stack.
JSON
nullvalues are encoded as light userdata containing theNULLpointer.Objects are converted to string-indexed tables.
Arrays are converted to sequence tables and are given a metatable. This makes it possible to distinguish between empty arrays and empty objects. The metatable is stored in the registry under key
'HsLua JSON array'' (see also jsonarray).JSON numbers are converted to Lua numbers, i.e., Number; the exact C type may vary, depending on compile-time Lua configuration.
