Call as
Conditions.hero_talent.listedSpec(spec)
Record the dependency Conditions.hero_talent.listedSpec, then call it by that name. A namespaced call does not pass self: use a colon call or pass the object yourself.
What it does
Returns the specialization ID when it is one of the player's own class's specializations, which are the only ones whose hero talent trees the game can list. Reads the class from UnitClass and the choices from Platform:GetClassSpecializationChoices.
Arguments
| Name | Type | What it does |
|---|---|---|
spec | number | nil | Specialization ID of the rotation being edited. |
Returns
| 1 | number | nil | The same ID when the player's class has it; nil otherwise, or when the class or the list cannot be read. |
|---|
Editions
Built In helpers are registered on every edition. What differs is the game API they read; where one is missing the helper falls back or returns nil with a reason.
- Not available on that edition (the reason is in the tooltip)
- Only while Blizzard's deprecation fallbacks are on
| Game API |  |  |  |  |  |

Secret values (Retail and Forever)
On Retail and Forever the game hands addons secret values. This helper checks what it reads (addon.Platform:CanReadValue) and returns nil with a reason such as restricted-value instead of a secret it cannot compare. Treat nil as unavailable, not as false.
How the addon calls it
- Hero Talent Tree (widget)
local listed = type(platform.GetHeroTreeChoices) == "function" and platform:GetHeroTreeChoices(listedSpec(spec))
