docs(faction): describe the reputation functions

Descriptors for GetFactionIDByIndex, GetFactionInfoByID, GetFactionParentID, the 17 undocumented C_Reputation functions, the FactionData structure, and the FACTION_STANDING_CHANGED event. C_Reputation.IsFactionInactive and SetFactionInactive mirror stock globals, but no Blizzard client has them under C_Reputation, so they are marked as ClassicAPI extensions.

+
+Returns an array of the ways that the dead player can resurrect themselves.
+Each entry is a `SelfResurrectOption` table:
+
+| Field | Type | Description |
+|---|---|---|
+| `name` | string | The name of the spell or the item. |
+| `optionType` | number | `Enum.SelfResurrectOptionType.Spell` (0) or `Enum.SelfResurrectOptionType.Item` (1). |
+| `id` | number | The spell ID or the item ID. |
+| `canUse` | boolean | Always `true`. |
+| `isLimited` | boolean | Always `false`. |
+| `priority` | number | Always `0`. |
+
+The array has one entry at most. A self-resurrection spell, such as
+Soulstone Resurrection or Reincarnation, comes before an item. The array is
+empty when the player is alive or a ghost, or has no option. The function
+returns nothing before the player enters the world.
+

+### `smf:GetMessageInfo(index)`
+
+On ScrollingMessageFrame. Returns one message of the frame: its text, its
+color, and the extra values that `AddMessage` got for the message. Index 1 is
+the oldest message, and `smf:GetNumMessages()` is the index of the newest
+message. If no message has the index, the function returns nothing. If
+`index` is not a number, the function gives an error.
+
+- `text` is the text that the frame keeps, with its color codes.
+- `r`, `g` and `b` are the color that the frame shows for the message. After
+  `UpdateColorByID` changes the color, these values also change. The frame
+  keeps each color value in steps of 1/255, so `0.5` returns as `0.50196…`.
+- `smf:AddMessage(text, r, g, b, ...)` keeps all the values after `b`.
+  `GetMessageInfo` returns these values in the same order, nil values
+  included.
+
+An addon that replaces `AddMessage` and gives only `text, r, g, b` to the
+original function removes the extra values.
+
+```lua
+ChatFrame1:AddMessage("hello", 1, 0.5, 0, 7, "extra")
+ChatFrame1:GetMessageInfo(ChatFrame1:GetNumMessages())
+-- "hello", 1, 0.50196078431373, 0, 7, "extra"
+
+for i = 1, ChatFrame1:GetNumMessages() do
+    local text, r, g, b = ChatFrame1:GetMessageInfo(i)   -- oldest message first
+end
+```
+
+### `smf:BackFillMessage(text, r, g, b, ...)`
+
+On ScrollingMessageFrame. Adds a message as the oldest message of the frame.
+`AddMessage` adds the newest message. `BackFillMessage` adds history behind
+the messages that the frame already has. An addon that rebuilds a frame from
+a history walks the history from the newest entry to the oldest and adds each
+entry with this function. The messages that the frame already has do not
+move.
+
+- `text`, `r`, `g`, `b` and the extra values work as in `AddMessage`.
+  Without `r`, `g` and `b`, the message takes the color of the frame's font.
+  `GetMessageInfo` returns the extra values after the color.
+- If the frame is at its line limit (`SetMaxLines`), the function drops the
+  message, because the message is older than each message that the frame
+  keeps.
+- If the frame is scrolled to the bottom, the frame shows the message when
+  there is room above its other lines. If the frame is scrolled up, the frame
+  keeps its view.
+
+```lua
+ChatFrame1:BackFillMessage("older", 1, 1, 1)
+ChatFrame1:GetMessageInfo(1)   -- "older", 1, 1, 1
+```
+
+### `smf:RemoveMessagesByPredicate(predicate)`
+
+On ScrollingMessageFrame. Removes the messages that `predicate` selects. The
+function calls `predicate(text, r, g, b, ...)` for each message, from the
+oldest to the newest, with the values that `GetMessageInfo` returns for the
+message. If `predicate` returns true, the function removes the message. The
+other messages keep their order. If `predicate` is not a function, the
+function gives an error.
+
+- The function calls `predicate` for all messages before it removes any
+  message. If `predicate` gives an error for a message, the frame keeps that
+  message.
+- The frame keeps its scroll offset (`GetScrollOffset`). If fewer messages
+  remain than the offset, the offset becomes the oldest message.
+- The frame shows the lines that remain at once. If no message remains, the
+  result is the same as `smf:Clear()`.
+
+```lua
+-- remove the messages that were added with the extra value 7
+ChatFrame1:RemoveMessagesByPredicate(function(text, r, g, b, id)
+    return id == 7
+end)
+```
+
+### `smf:SetScrollOffset(offset)` / `smf:GetScrollOffset()` / `smf:GetMaxScrollRange()` / `smf:ScrollByAmount(amount)`
+
+On ScrollingMessageFrame. The scroll offset is the number of lines that the
+frame is scrolled away from the newest message. When the frame is not
+scrolled, the offset is 0. The largest offset is `GetMaxScrollRange()`, that
+is `GetNumMessages() - 1`, or 0 for an empty frame. At that offset, the oldest
+message is the bottom line, or the top line in TOP insert mode.
+
+- `SetScrollOffset(offset)` scrolls to `offset`. An offset less than 0 or
+  more than `GetMaxScrollRange()` changes to the nearest limit.
+- `ScrollByAmount(amount)` adds `amount` to the offset. A positive amount
+  scrolls to older messages. The function also shows the faded lines
+  again, also when the offset does not change.
+- If `offset` or `amount` is not a number, the function gives an error.
+
+```lua
+ChatFrame1:ScrollByAmount(3)     -- 3 lines up
+ChatFrame1:GetScrollOffset()     -- 3
+ChatFrame1:SetScrollOffset(ChatFrame1:GetMaxScrollRange())   -- the oldest message
+ChatFrame1:SetScrollOffset(0)    -- the newest message again

+// option can be used and none is limited.

+// SELF_RES_SPELL_CHANGED is 4.3.4's: CGPlayer_C::SetActiveMirrorHandlers
+// watches PLAYER_SELF_RES_SPELL with OnUpdatePlayerScriptEvent. 1.12 watches

+// Tall inline icons move the edit box's rows.
+//
+// A multi-line edit box places its caret, its selection pieces and a click's
+// cursor by rows of one height — the label's font height plus its spacing,
+// pixel-aligned (FUN_EDITBOX_PLACE_CARET, FUN_EDITBOX_PLACE_SELECTION_PIECE,
+// FUN_EDITBOX_INDEX_AT_POINT; 4.3.4's UpdateVisibleCursor, UpdateHighlightArea
+// and ConvertCoordinateToIndex step the same rows). The label's text leaves
+// those rows once a line holds an icon taller than the font: the render moves
+// that line and every line after it down by the overflow (4.3.4's
+// InitializeText; the emitter co-hook in Text::InlineTexture), and the box
+// grows by the same amount through the string-height co-hook. So below the
+// first tall-icon line the caret and the highlight sat above their text by
+// the summed overflow, and OnCursorChanged reported that y, which
+// ScrollingEditBoxMixin:ScrollCursorIntoView scrolls by — pfUI's chat copy
+// box with faction-emblem icons. 4.3.4 has the same fault; nothing it ships
+// puts a tall icon in an edit box.
+//
+// Each placer keeps its engine code and gets the move the render makes, from
+// Text::InlineTexture::LineIconShift over the box's own line table (the
+// breaks the render lays out), split by the label's vertical justify as the
+// emitter splits it:
+//   - the click: its y is moved onto the uniform row that the icon-aware row
+//     under it has, before the engine maps it;
+//   - a selection piece: re-anchored after the engine placed it, with the
+//     engine's own x, lower by the move;
+//   - the caret: the same re-anchor, then OnCursorChanged fired once with the
+//     moved y through the engine's own forwarder. The engine's fire is muted
+//     for the call by emptying the script slot: it reads the row y before
+//     anything can correct it.
+// A single-line box has one row and needs nothing: its label is justified
+// MIDDLE in a rect of fixed height, so its text stays centred on the caret.

+// `ScrollingMessageFrame:GetMessageInfo(index)`, retail's: the message's
+// text, its colour, then every argument AddMessage took after the colour.
+//
+// Retail's ScrollingMessageFrame is a Lua mixin whose AddMessage(message, r,
+// g, b, ...) packs the call into an entry and GetMessageInfo unpacks it
+// (Blizzard_SharedXML/ScrollingMessageFrame.lua). Index 1 is the oldest
+// message; the extra arguments come back as given, nils and count included;
+// an index outside 1..GetNumMessages() returns nothing. (4.3.4's C method
+// returns text, accessID, typeID, extraData instead.)
+//
+// The text and colour come from the engine's own record of the message
+// (Offsets.h, OFF_SCROLLINGMESSAGEFRAME_MESSAGES), so a colour
+// UpdateColorByID changed reads back changed, as retail's AdjustMessageColors
+// does. The record keeps the colour as bytes, so a component reads back as
+// byte/255. It keeps the first extra argument only as an integer (0 for
+// anything else), so the extra arguments are kept beside the ring instead.
+//
+// AddMessage is registered again on the ScrollingMessageFrame registry, over
+// the engine's. The registrar (0x00701D80) adds a node for the name whatever
+// is there; Storm's TSHashTable::InternalNew links a new node at the head of
+// its bucket (NewNode(1)), and the method lookup (0x00702000) returns the
+// first match, so this one answers. It runs the engine's AddMessage, then
+// records the extra arguments for the record the engine wrote. The engine
+// adds a message exactly when the text is a nonempty string
+// (0x0079299C..0x007929C7: lua_isstring, lua_tostring, first byte); a bad
+// `self` raises a Lua error instead. The ring's one writer has no other
+// caller, so every record was written through here.
+//
+// The extra arguments live in a registry table keyed by the frame's Lua table,
+// then by record. A record's table is refilled when the record is overwritten,
+// so a full ring makes no garbage.
+//
+// `BackFillMessage(text, r, g, b, ...)`, retail's, adds a message as the
+// OLDEST — the combat log's refilter walks its history newest to oldest and
+// fills the frame behind the lines it already shows (Blizzard_CombatLog's
+// RefilterUpdate). It writes the ring itself; see the function.
+//
+// `RemoveMessagesByPredicate(predicate)`, retail's, removes the messages the
+// predicate selects by their GetMessageInfo values. The ring has no
+// compaction of its own; 4.3.4's RemoveLines loop is run over it, the
+// extra-argument tables moving with their records. See the function.

+//
+// Retail's offset (Blizzard_SharedXML/ScrollingMessageFrame.lua) counts the
+// lines the frame is scrolled up from the newest message, 0 at the bottom, up
+// to GetMaxScrollRange() = max(GetNumMessages() - 1, 0), where the oldest
+// message is the bottom line - the place 1.12's own ScrollToTop goes. 1.12
+// keeps the same offset: ScrollToOffset and ScrollOffset (Offsets.h) are its

+// outside it, so the setters clamp first. SetScrollOffset to the offset the
+// frame has does nothing, as on retail. ScrollByAmount always calls the
+// engine, which re-arms the shown lines' fade when the offset stays: retail's

+// `UnitHasIncomingResurrection(unit)` and `INCOMING_RESURRECT_CHANGED` —
+// 4.3.4's CGIncomingResurrection (Ui/IncomingResurrection.cpp) and the two
+// calls its spell code makes into it:
+//   - SMSG_SPELL_START: a spell with a resurrect effect and an object target
+//     adds {caster, spell} under that target
+//     (PendingSpellCast::OnSpellStartPacket, 0x008ACD80);
+//   - the cast's end removes it (FinishPendingSpellCast, 0x008AF840, which
+//     SPELL_GO and every failure run).
+// Each change signals INCOMING_RESURRECT_CHANGED to every token naming the
+// target, or the corpse's owner when the target is a corpse
+// (Script_SendUnitSignal). The query answers for the unit itself, then for
+// its corpse (HasIncomingResurrection, 0x009FCF80).
+//
+// Where 1.12 differs:
+//   - Resurrect effects. 4.3.4 tests effect 18 alone. 1.12's class
+//     resurrections (Resurrection, Redemption, Ancestral Spirit, Rebirth,
+//     every rank) carry 113, RESURRECT_NEW, and 18 only item and NPC spells
+//     (Spell.dbc), so both count.
+//   - The cast's end. 1.12 keeps no pending cast. Its end is the caster's
+//     SMSG_SPELL_GO, or CGUnit_C::ClearCastingSpell and the failure packets,
+//     which `Spell::Cast` owns and reports through OnCastEnded. Turtle sends
+//     observers no failure packet on an interrupt; SuperWoW calls
+//     ClearCastingSpell instead (docs/notes/cast-channel.md).
+//   - Lifetime. 4.3.4 empties the table on entering and leaving the world. A
+//     cast whose caster leaves view never reports its end, so an entry whose
+//     caster is no longer visible ends on the next world tick, which covers
+//     a world change as well.
+//   - One cast per caster, as the unit's single precast slot (+0xC8C) holds:
+//     a caster's new resurrection replaces its last.

Brues	77b304ae68	feat(smf): RemoveMessagesByPredicate ScrollingMessageFrame:RemoveMessagesByPredicate(predicate), retail's: the predicate is called with each message's GetMessageInfo values, oldest first, and the messages it returns true for are removed; the rest keep their order. It covers 4.3.4's RemoveMessagesByAccessID / ByExtraData, whose int fields the retail-shaped records here do not have. 1.12's ring has no compaction of its own; the removal is 4.3.4's RemoveLines loop over it: every kept record moves forward in ring order to the first free slot (freeing the text it lands on, nulling the one it left), the position moves back by the removed count, and the extra-argument tables move with their records. Then the engine's own layout (0x00788750) from the record at the kept scroll offset, clamped to the oldest, and its re-arm (0x00788B80) - a layout at the bottom keeps the fade state, so 4.3.4 re-arms after - or its Clear (0x007882B0) when nothing is kept. The predicate runs for every message before anything moves, through the engine's error handler; a predicate that errors keeps that message, as retail's safesecurecall does. GetMessageInfo shares its record lookup and value push with it.	2026-10-30 02:14:08 -05:00
Brues	c965e49117	feat(smf): BackFillMessage ScrollingMessageFrame:BackFillMessage(text, r, g, b, ...), retail's: the message becomes the oldest, for rebuilding a frame from history newest to oldest (Blizzard_CombatLog's refilter adds each entry with it). The ring's writer 0x00788150 has one slot rule: the one after the newest. BackFillMessage writes the slot 4.3.4's AddMessage(..., addToTop) picks — the free one before the oldest, (pos - count + 1) mod max once the count has grown — and fills the record as the writer does: a Storm copy of the text, AddMessage's colour (clamped, x255 + 0.5 truncated, alpha 0xFF; the font's without r, g, b), shown, the frame's two times, id 0, and the extra arguments kept for GetMessageInfo. Nothing already in the ring moves, so a scrolled-up frame keeps its view; at the bottom the lines are laid out again from the newest, as the writer does. A frame at its line limit drops the message, as retail's CircularBuffer PushBack does ("Won't overwrite front"); 4.3.4 overwrites the oldest slot there, which Blizzard_CombatLog never reaches.	2026-10-30 01:45:47 -05:00
Brues	ead52e79ce	fix(editbox): caret, selection and click rows follow tall inline icons A multi-line edit box places its caret, selection pieces and a click's cursor by rows of one height (font height + spacing, pixel-aligned), while the render moves a line holding an icon taller than the font, and every line after it, down by the overflow, and the box grows to match. Below the first tall-icon line the caret and highlight sat above their text, and OnCursorChanged reported that y, so ScrollingEditBoxMixin's scroll-into- view stopped short (pfUI chat copy with faction emblems). 4.3.4's CSimpleEditBox has the same fault: UpdateVisibleCursor, UpdateHighlightArea and ConvertCoordinateToIndex are icon-blind too. So this goes past 4.3.4, as editbox/CharClass does. EditBox::IconRows co-hooks the three placers and gives each the render's move, from the new Text::InlineTexture::LineIconShift over the box's own line table: the click's y is mapped onto the uniform row before the engine reads it; the selection piece and caret are re-anchored after, with the engine's own x; the caret's OnCursorChanged is muted for the original call and fired once with the corrected y through the engine's forwarder, with the same packing PlaceCaret uses (verified in the disassembly and the binary's constants). Also fixes the "caret positioner" misnomer for 0x77DE70 (the selection- piece placer) in Offsets.h and the docs.	2026-10-30 01:15:01 -05:00
Brues	7cb6cda101	feat(smf): TOP insert mode SetInsertMode(SCROLLING_MESSAGE_FRAME_INSERT_MODE_TOP) now shows the newest message at the top, older ones below it, as retail's mixin does. 1.12's line layout anchors each line once, when it makes it, through one SetPoint call (0x00788975). That call is redirected: lines of a TOP frame take the TOP anchors, every other line keeps the engine's own arguments. The layout remakes the lines when the frame resizes, so the redirect covers that too. A mode change re-anchors the existing lines with the layout's own steps and refreshes the display. Insert mode moves out of Scroll.cpp into InsertMode.cpp.	2026-10-30 00:20:19 -05:00
Brues	5ab497f2c7	feat(smf): scroll offset, insert mode, display-refreshed callbacks Retail's ScrollingMessageFrame SetScrollOffset, GetScrollOffset, GetMaxScrollRange, ScrollByAmount, SetInsertMode / GetInsertMode with the SCROLLING_MESSAGE_FRAME_INSERT_MODE_* globals, and AddOnDisplayRefreshedCallback, which ScrollUtil's InitScrollingMessageFrameWithScrollBar calls. The offset is the engine's own: SetScrollFromBottom's body (0x00788700) is 4.3.4's SetScrollOffset step for step, and GetCurrentScroll is GetScrollOffset under retail's name. The setters clamp to 0..GetNumMessages()-1 first, as retail does; the engine wraps. 1.12's layout stacks lines bottom-up only, so the insert mode is BOTTOM and SetInsertMode raises an error for anything else. The callbacks run after the frame's own update (0x00788460, OnUpdate then the fader), where retail's OnPostUpdate runs them, for a frame the line layout, AddMessage or ScrollByAmount marked. The layout hook moves out of Text::InlineTexture into ScrollingMessageFrame::Layout, which owns it and fans out to both.	2026-10-29 23:56:24 -05:00
Brues	205d1fd43b	feat(smf): ScrollingMessageFrame GetMessageInfo Retail's smf:GetMessageInfo(index): text, r, g, b, then every argument AddMessage took after the colour. Index 1 is the oldest message, and an index outside 1..GetNumMessages() returns nothing. The text and colour come from the engine's record in the frame's message ring, so UpdateColorByID's changes read back. The record keeps only an integer id after the colour, so AddMessage is registered again over the engine's: Storm's hash links a new method node at the head of its bucket and the lookup takes the first match. It runs the engine's AddMessage, then keeps the extra arguments for the record just written, in a registry table reused per record.	2026-10-29 23:43:45 -05:00
Brues	950c9deb76	feat(death): C_DeathInfo self-resurrect options, SELF_RES_SPELL_CHANGED C_DeathInfo.GetSelfResurrectOptions, C_DeathInfo.UseSelfResurrectOption and Enum.SelfResurrectOptionType over what 1.12 already serves through HasSoulstone and UseSoulstone. Both pick one option the same way: PLAYER_SELF_RES_SPELL when the server set it, else the first carried item whose on-use spell is a self-resurrect. The list holds that option under HasSoulstone's alive gate, and using it calls the engine's UseSoulstone. Nothing in 1.12 limits a self-resurrection, so canUse is true, isLimited false and priority 0. SELF_RES_SPELL_CHANGED is 4.3.4's watcher on PLAYER_SELF_RES_SPELL from SetActiveMirrorHandlers. 1.12 watches no such field, so the watcher joins CGPlayer_C::AddActiveWatchers and leaves before its removal, the lifetime of the engine's own player watchers.	2026-10-29 20:37:40 -05:00
Brues	e7ccc11309	feat(unit): UnitHasIncomingResurrection, INCOMING_RESURRECT_CHANGED 4.3.4's CGIncomingResurrection. SMSG_SPELL_START adds a resurrect cast under its object target, a unit or a corpse. SMSG_SPELL_GO, the failure packets and ClearCastingSpell (through Spell::Cast, Turtle's only interrupt signal) end it. A cast whose caster leaves view never reports its end, so it ends on the next world tick. Each change fires the event for every token naming the target, or the corpse's owner. 1.12's class resurrections carry effect 113, not 4.3.4's 18, so both count. Object::Corpse::ByOwner, lifted from spell/Range.cpp, now skips bones as 4.3.4's ClntObjMgrFindCorpseByOwner does. Turtle's bones keep their owner, so old bones hid a ghost's live corpse, from this API and from the range check's ghost redirect. HasEffect moves from CombatLog to Spell::Lookup, and the SpellCastTargets object mask 0x8A02 becomes one Offsets.h constant.	2026-10-29 19:21:47 -05:00
Brues	bab31b5f7b	docs(unit): bound the GetShapeshiftForm example to the bar GetShapeshiftForm returns the bar count + 1 for a form that is not on the stance bar, as 3.3.5 and 4.3.4 do. The example passed that index to GetShapeshiftFormInfo, which returns nils for it.	2026-10-28 23:31:49 -05:00
Brues	e0e24bab34	feat(macro): SetMacroDisplay range unit C_Macro.SetMacroDisplay(macroSlot, value [, unit]) takes the unit the button's range check uses, so a publisher's [@unit] reaches the range check as SetMacroSpell's target does. The token stays a token: each lookup resolves it again, so the range follows a new mouseover, focus or target with no republish. A token that names no unit leaves the target in charge. The engine's resolver vets the unit at publish and raises its "Unknown unit name" error for anything else, as UnitExists does. It tells a token's family from its spelling alone, so a token that passes once never raises at a later lookup. The unit is ignored for false and for an empty value, and a publish that changes only the unit updates it.	2026-10-28 23:19:36 -05:00
