* script_lua.c unit provides shared functionality between

|
* eval.c and function_lua.c. Functionality provided:
|
|
*
|
|
* * Execute Lua code, assuming that the code is located on
|
|
* the top of the Lua stack. In addition, parsing the execution
|
|
* result and convert it to the resp and reply ot the client.
|
|
*
|
|
* * Run Redis commands from within the Lua code (Including
|
|
* parsing the reply and create a Lua object out of it).
|
|
*
|
|
* * Register Redis API to the Lua interpreter. Only shared
|
|
* API are registered (API that is only relevant on eval.c
|
|
* (like debugging) are registered on eval.c).
|
|
*
|
|
* Uses script.c for interaction back with Redis.
