Foreign.Lua.Aeson

Orphan instances

Description

Glue to hslua for aeson values.

This provides a StackValue instance for aeson's Value type. The following conventions are used:

Null values are encoded as the special global _NULL. Using Nil would cause problems with null-containing arrays.
Objects are converted to tables in a straight-forward way.
Arrays are converted to lua tables. Array-length is included as the value at index 0. This makes it possible to distinguish between empty arrays and empty objects.

Synopsis

Documentation

registerNull :: Lua () Source #

Create a new lua state suitable for use with aeson values. This behaves like newstate in hslua, but initializes the _NULL global. That variable is used to encode null values.
