Readme for hslua-aeson-1.0.2

[back to package description]

hslua-aeson

travis build status MIT License

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 a special value (stored in the registry field HSLUA_AESON_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.

  • JSON numbers are converted to Lua numbers (usually doubles), which can cause a loss of precision.
