1.2.12. Data storage function
storage object provides persistent key-value data storage for user scripts. Only the following Lua
data types are supported:
•
boolean
•
number
•
string
•
table
storage.set(key, value)
Sets new value for the given key. Old value is overwritten. Returns boolean as the result and an
optional error string.
storage.get(key, default)
Gets value for the given key or returns default value ( nil if not specified) if key is not found in
the data storage.
Note: all user scripts share the same data storage. Make sure that same keys are not used to store
different types of data.
Examples
•
The following examples shows the basic syntax of storage.set . Result will return
boolean true since the passed parameters are correct
result = storage.set
( 'my_stored_value_1'
, 12.21
)
•
This example will return false as the result because we are trying to store a function
which is not possible.
1. testfn
= function (
t
)
2. return t * t
3. end
4. result
=
storage.set
( 'my_stored_value_2'
, testfn
) -- this will result in an error
