Annotations, Hover

Expected Behaviour

On hover over action param in my function I'd like to get annotation consistent with already existing annotation that i get if i hover over all in actions.all :

(field) actions.all: {
    [10]: string = "supportAttack",
    [11]: string = "supportDefence",
    [12]: string = "supportBoth",
    [13]: string = "supportAttackPike",
    [14]: string = "supportDefencePike",
    [15]: string = "stanceShieldwall",
    [16]: string = "stanceLastman",
    [17]: string = "stanceBarrage",
    [18]: string = "encamp",
    [19]: string = "uncamp",
    [1]: string = "retreat",
    [20]: string = "destroyCamp",
    [21]: string = "buildFort",
    [22]: string = "demountFort",
    [23]: string = "destroyFort",
    [24]: string = "rest",
    [25]: string = "respire",
    [2]: string = "move",
    [3]: string = "swap",
    [4]: string = "forcedMove",
    [5]: string = "melee",
    [6]: string = "shoot",
    [7]: string = "shoot2",
    [8]: string = "breakthrough",
    [9]: string = "enclosing",
}

Essentially i'd like enum for this array to give the same behavioir as alias like this

---@alias Action
---| '"retreat"'
---| '"move"
---| '"swap"' 
---| '"forcedMove"'
---| '"melee"'
---| '"shoot"'
---| '"shoot2"'
---| '"breakthrough"
---| '"enclosing"'
---| '"supportAttack"'
---| '"supportDefence"'
---| '"supportBoth"'
---| '"supportAttackPike"'
---| '"supportDefencePike"'
---| '"stanceShieldwall"'
---| '"stanceLastman"'
---| '"stanceBarrage"'
---| '"encamp"'
---| '"uncamp"'
---| '"destroyCamp"'
---| '"buildFort"'
---| '"demountFort"'
---| '"destroyFort"'
---| '"rest"'
---| '"respire"'

Actual Behaviour

On hover over action param in my function I get this annotation:

(parameter) action: Action
{
}

Reproduction steps

Consider this minimal code snippet:

local actions = {}

---@enum Action
actions.all = {
  "retreat",
  "move",
  "swap",
  "forcedMove",
  "melee",
  "shoot",
  "shoot2",
  "breakthrough",
  "enclosing",
  "supportAttack",
  "supportDefence",
  "supportBoth",
  "supportAttackPike",
  "supportDefencePike",
  "stanceShieldwall",
  "stanceLastman",
  "stanceBarrage",
  "encamp",
  "uncamp",
  "destroyCamp",
  "buildFort",
  "demountFort",
  "destroyFort",
  "rest",
  "respire",
}

actions.isStance = {stanceShieldwall = true, stanceLastman = true, stanceBarrage = true}

--- @param action Action
--- @return boolean
function actions.IsStance(action)
  return actions.isStance[action]
end

Inizia con la riproduzione minima in Lua nell’issue e traccia come vengono rappresentati al passaggio del mouse l’annotazione @enum su actions.all e il parametro Action. Confronta questo percorso con il comportamento esistente degli alias. Il lavoro è completato quando passando il mouse sul parametro Action vengono esposti i membri string dell’enum in modo coerente con il risultato del passaggio del mouse su actions.all.
