Type Checking

Expected Behaviour

When assigning a class/key-value table to a type defined as an array, a diagnostics error should be raised.

Actual Behaviour

No diagnostics error is raised.

Reproduction steps

local dict = {a = 'a'}

---@type number[]
local array = dict

Observe that no diagnostics error is raised when assigning dict to array, which is defined as an array.

Additional Notes

lua-langauge-server should check for the presence of non-integer indices in a table. If there are any, the table should not match the array type.

I believe the present issue is the underlying issue in #1721.

Version

3.13.6-1

L’issue non indica alcun file sorgente né alcun test. Inizia eseguendo la riproduzione Lua fornita con lua-language-server 3.13.6-1 e traccia il percorso del controllo dei tipi per l’assegnazione da tabella ad array. Il lavoro è concluso quando viene segnalata una diagnostic per una tabella contenente una chiave non intera, mentre gli array validi continuano a essere accettati.
