Introduce ClassicAPI.lua, a feature-detection layer for the ClassicAPI client mod that mirrors NampowerAPI's HasMinimumVersion pattern (IsAvailable / HasMinimumVersion / HasUnitAuras). UnitHasDispelType scans a unit's auras via C_UnitAuras and reports the dispel type, scanning debuffs or buffs based on a helpful flag. Add conditionals backed by it: - Debuff side (defensive cleanse): [magic] [curse] [disease] [poison] [dispellable] + negations - Buff side (offensive dispel/strip): [magicbuff] [dispellablebuff] + negations All are no-arg booleans, default to @target (honor @unit), and degrade gracefully without ClassicAPI: positive checks return false, negated return true, since vanilla cannot read aura dispel types. The existing ValidateAura path is untouched. MacroErrorChecker auto-accepts them via the Keywords table; they're registered in BOOLEAN_CONDITIONALS so they parse as flags. Loaded after NampowerAPI in the TOC.

# ClassicAPI Adoption Backlog
|
|
|
|
Opportunities to use [ClassicAPI](https://github.com/) (`C:\Git\ClassicAPI`, see
|
|
`docs/API.md`) in SuperCleveRoidMacros. ClassicAPI is a client mod (sibling to
|
|
nampower/SuperWoW) that backports the modern `C_*` API into the 1.12.1 client.
|
|
We already gate nampower behind version detection — every ClassicAPI path below
|
|
must follow the same pattern: **feature-detect, then fall back to the current
|
|
implementation** so users without ClassicAPI are unaffected.
|
|
|
|
API references are line numbers into `C:\Git\ClassicAPI\docs\API.md`.
|

|
## Tier 1 — high impact (new capabilities, not just refactors)
|
|
|
|
### 1. `C_UnitAuras` — native aura data for any unit
|
|
- **API:** `API.md:8670` — `GetAuraDataBySpellName(unit, name, filter)`,
|
|
`GetUnitAuraBySpellID(unit, spellID, filter)`, `GetAuraDataByIndex`.
|
|
- Returns `spellId`, `dispelName` (`"Magic"`/`"Curse"`/`"Disease"`/`"Poison"`),
|
|
`applications` (stacks), `duration`.
|
|
- **Unlocks:** `[dispellable]` / `[curse]` / `[magic]` target conditionals and
|
|
spellID-based (rank/locale-proof) aura matching.
|
|
- **Caveat:** `expirationTime` is only populated for `unit=="player"`; it's `0`
|
|
for target/focus (vanilla server limitation). Target debuff *timers* still
|
|
need the existing libdebuff tracking — only presence/stacks/school/spellId
|
|
are reliable cross-unit.
|
|
|
|
- **DONE (slice 1 — dispel-type conditionals):** added `ClassicAPI.lua`
|
|
detection module (`CleveRoids.ClassicAPI`, mirrors NampowerAPI's
|
|
`HasMinimumVersion`) and the `[magic]`/`[curse]`/`[disease]`/`[poison]`/
|
|
`[dispellable]` conditionals + negations, backed by
|
|
`C_UnitAuras.GetDebuffDataByIndex(...).dispelName`. No-arg booleans, honor
|
|
`@unit`, graceful fallback (positive→false, negated→true) when ClassicAPI is
|
|
absent. Purely additive — the existing `ValidateAura` path is untouched.
|
|
- **DONE (slice 2 — buff-side / offensive dispel):** `UnitHasDispelType` now
|
|
takes a `helpful` flag (scans `GetBuffDataByIndex`), exposed as
|
|
`[magicbuff]`/`[dispellablebuff]` + negations — detect a dispellable buff to
|
|
strip off an enemy (e.g. `[harm,magicbuff] Dispel Magic`). Magic-only is the
|
|
practical set since 1.12 offensive dispel removes Magic buffs.
|
|
- **Follow-ups (still TODO):**
|
|
- spellID-based aura matching via `GetUnitAuraBySpellID` (rank/locale-proof),
|
|
optionally wired into `ValidateAura` as a fast path with libdebuff fallback.
|
|
- more reliable cross-unit stacks via `applications`.
|
|
- class-aware `[dispellable]` (only types this character can actually remove).
|
|
- optional name filtering on the type keywords (e.g. `[magic:Polymorph]`).
|
|
|
|
### 2. `C_Item.GetWeaponEnchantInfo()` — temp-enchant IDs
|
|
- **API:** `API.md:7159` — returns 12-tuple including `enchantID` for main/off/ranged.
|
|
- **Unlocks:** detect *which* temp enchant (poison/oil/sharpening stone) is
|
|
applied to a weapon, not just that one exists.
|
|
- **Naming:** `[poison]` is now taken by the target dispel-type conditional
|
|
(slice 1 above). Use weapon-specific keywords for this — e.g.
|
|
`[mhenchant:<id>]` / `[ohenchant:<id>]` (or `[mhpoison:<id>]`/`[ohpoison:<id>]`),
|
|
not a bare `[poison]`.
|
|
- Vanilla's global only reports presence; this is a genuinely new capability
|
|
(rogue/shaman/enhance).
|
|
|
|
### 3. `GetUnitSpeed(unit)` + `IsFalling()` / `IsSwimming()`
|
|
- **API:** `API.md:8312`, `API.md:7629`.
|
|
- **Replaces today:** MonkeySpeed addon dependency (which needs SuperWoW
|
|
`UnitPosition`) for `[moving]` — `Conditionals.lua:2981`.
|
|
|
|
---
|
|
|
|
## Tier 2 — replace custom scanning / extra deps
|
|
|
|
### 4. `C_Spell.*` / `GetSpellInfo(spellID)`
|
|
- **API:** `API.md:6649+` — `GetSpellCooldown`, `IsUsableSpell`, `IsSpellKnown`,
|
|
`SpellHasRange`, `GetSpellSchool`, `FindSpellBookSlotByID`.
|
|
- **Replaces today:** spellbook scanning via `GetSpellName(i, BOOKTYPE_SPELL)`
|
|
(`Conditionals.lua:2500`) and the Slam-slot hack. Simplifies `[known]`,
|
|
`[usable]`, range checks.
|
|
|
|
### 5. `C_Timer.After` / `NewTicker` (+ coroutines)
|
|
- **API:** `API.md:8008+`.
|
|
- **Replaces today:** manual `OnUpdate` frames (`Core.lua:5082`, `:80`, `:460`)
|
|
and the UnitXP aura-cleanup timer (`Conditionals.lua:1474`).
|
|
|
|
### 6. `UnitGUID` / `UnitTokenFromGUID`
|
|
- **API:** `API.md:8206+`.
|
|
- **Replaces today:** SuperWoW GUIDs in ComboPointTracker (`ComboPointTracker.lua`).
|
|
- **Verify first:** confirm GUID string format matches SuperWoW's before swapping.
|
|
|
|
### 7. Native `focus` token + `FocusUnit`/`ClearFocus` + `PLAYER_FOCUS_CHANGED`
|
|
- **API:** `API.md:2624+`.
|
|
- **Replaces today:** custom/pfUI focus resolution (`Conditionals.lua:5799`, `:3148`).
|
|
Gives engine-backed `@focus` for non-pfUI users.
|
|
|
|
---
|
|
|
|
## Tier 3 — situational
|
|
|
|
- **`C_NamePlate.GetNamePlates()` / `nameplateN` tokens** (`API.md:5742+`) —
|
|
alternative to UnitXP enemy enumeration for AoE counting (`Conditionals.lua:3099`).
|
|
- **`GetShapeshiftFormID()` + `UPDATE_SHAPESHIFT_FORM`** (`API.md:7792`) —
|
|
cleaner stance/form conditionals.
|
|
- **`CastSpellNoToggle` / numeric spellIDs in `/cast`** (`API.md:5336+`) —
|
|
rank-specific casting by ID, no-toggle behavior; could back a `/cast <spellID>`.
|
|
- **State helpers** `IsStealthed` / `IsMounted` / `UnitStandState` (`API.md:7574+`) —
|
|
back simple `[stealth]` / `[mounted]` / `[standing]` conditionals.
|
|
|

|
|
|
## Cross-cutting requirement
|
|
|
|
Gate **every** ClassicAPI path behind feature-detection with graceful fallback,
|
|
mirroring the nampower `HasMinimumVersion` pattern (`Conditionals.lua:227`):
|
|
|
|
```lua
|
|
if C_UnitAuras and C_UnitAuras.GetAuraDataBySpellName then
|
|
-- ClassicAPI path
|
|
else
|
|
-- existing libdebuff/tooltip path
|
|
end
|
|
```
