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

Commencez par la reproduction minimale en Lua dans l’issue et suivez la manière dont l’annotation @enum sur actions.all et le paramètre Action sont représentés au survol. Comparez ce chemin avec le comportement existant des alias. C’est terminé lorsque le survol du paramètre Action expose les membres string de l’enum de manière cohérente avec le résultat du survol de actions.all.
