Wanting a SSD for Digiline systems? #

So here is the Datacard mod, SSD for Digiline! There are three types of datacards, that can store up to 800 datablocks. Punch a diskdrive with a datacard to insert it, and punch it again to take the datacard out.

Messages sent by the diskdrive #

responce_type = "inject" #

Sent when a datacard is injected into a diskdrive.

{
	responce_type = "inject",
}

responce_type = "eject" #

Sent when a datacard is ejected, either because a user punched it, or requested by another digiline signal.

{
	responce_type = "eject",
	id = ..., -- Only when requested via digiline
}

Digiline API #

A request to the datacard diskdrive must be in table form:

{
	type = "read" or "write",
	data = ..., -- only when type == "write"
	id   = ..., -- Kept intact in every responces
}

In every responces, including the error ones, the ID will be kept.

type = "read" #

The responce table would be like this:

{
	responce_type = "read",
	success = true,
	data = ..., -- the data of the disk or nil
	used = 0, -- used datablocks
	capacity = 800, -- maximum usable datablocks
}

type = "write" #

The data field is required to store data, use nil to clear the data in a datacard.

The responce table would be like this:

{
	responce_type = "write",
	success = true,
	used = 0, -- used datablocks
	capacity = 800, -- maximum usable datablocks
}

type = "eject" #

This type of request ejects the datacard.

A normal eject responce will be returned.

Errors #

An error responce is like this:

{
	responce_type = "read" or "write",
	success = false,
	error = "ERROR_CODE",
}

Error Codes #

• TOO_BIG: The data is too big for the datacard inserted into the diskdrive.
  Appear only on write requests
• ERR_SERIALIZE: A serialize bug happened. A possible reason is that the data is too large for the engine to handle.
  Appear only on write requests
• NO_DISK: There are no datacards in the diskdrive.
• UNKNOWN_CMD: The type value is not "read" or "write".
