Type Checking

Expected Behaviour

we have a (generated) class like

---@class GlobalModSettings
---@field ["heat-visualizer-updates-per-surface-per-tick"] ModSetting<int32>
---@field ["nixie-tube-update-speed-alpha"] ModSetting<int32>
---@field ["nixie-tube-update-speed-numeric"] ModSetting<int32>
---@field [string] ModSetting<(int32)|(double)|(boolean)|(string)|(Color)>

which has narrower types for the known entries and a general type for the "everything else" field, but when i then use this type like

local x = settings.global["heat-visualizer-updates-per-surface-per-tick"]

x is given the type from the [string] field, rather than the one that is an exact match for that specific string

Non è indicato alcun file del repository né alcun test. Inizia riproducendo la ricerca annotata di GlobalModSettings nel Lua language server tramite la Visual Studio Code extension, quindi traccia la risoluzione dei tipi dei campi indicizzati. Il lavoro è completato quando un campo con una chiave stringa esatta riceve il suo tipo più specifico invece del tipo di campo più ampio [string].
