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

該 issue 未指定原始檔案或測試。首先使用 lua-language-server 3.13.6-1 執行提供的 Lua 重現，並追蹤 table-to-array 指派的型別檢查路徑。當包含非整數索引鍵的表格觸發 diagnostic，而有效陣列仍被接受時，即表示完成。
