 324 Convert given Lua data into a JSON string.
 325
 326 This function recursively converts the given Lua data into a JSON string,
 327 ignoring any unsupported data. Lua tables are converted into JSON arrays if they
 328 only contain integer keys, mixed tables are turned into JSON objects with any
 329 existing numeric keys converted into strings.
 330
 331 Lua functions, coroutines and userdata objects are ignored and Lua numbers are
 332 converted to integers if they do not contain fractional values.

 335
 336 <h3>Parameters</h3>
 337 <ul>
 338
 339         <li>

 341         </li>
 342
 343         <li>
 344           pretty: A boolean value indicating whether the resulting JSON should be
 345         pretty printed.
 346         </li>
 347
 348 </ul>
 349
 350
 351
 352
 353 <h3>Usage:</h3>
 354 <pre>json = luci.jsonc.stringify({ item = true, values = { 1, 2, 3 } })
