// Example how to interop with JSON.

// Test loading some JSON, converting it to a binary FlatBuffer and back again.

// First read the schema and JSON data.
let schema = read_file("monster.fbs", true)
let json = read_file("monsterdata.json", true)
assert schema and json

// Parse JSON  to binary:
let fb, err1 = flatbuffers_json_to_binary(schema, json, [])
assert not err1

// Access one field in it, just to check:
let monster = MyGame_Sample_GetRootAsMonster(fb)
assert monster.name == "Orc"

// Convert binary back to JSON:
let json2, err2 = flatbuffers_binary_to_json(schema, fb, [])
assert not err2

// The generated JSON should be exactly equal to the original!
assert json == json2

// Print what we've been converting for good measure:
print json
