Readers

Inlet has built-in support for three input file languages: JSON, Lua, and YAML. Due to language features, not all readers support all Inlet features. Below is a table that lists supported features:

Table 13 Supported Language Features

	JSON	Lua	YAML
Primitive Types	bool, double, int, string	bool, double, int, string	bool, double, int, string
Dictionaries	X	X	X
Arrays	X	X	X
Non-contiguous Arrays		X
Mixed-typed key Arrays		X
Callback Functions		X

Extra Lua functionality

Inlet opens four Lua libraries by default: base, math, string, package. All libraries are documented here.

For example, you can add the io library by doing this:

  // Create Inlet Reader that supports Lua input files
  auto lr = std::make_unique<axom::inlet::LuaReader>();

  // Load extra io Lua library
  lr->solState().open_libraries(sol::lib::io);

  // Parse example input string
  lr->parseString(input);
