4DBug	447230e688	CI/releases: drop the nodemo bundles (--no-demo build flag kept); remove examples/example_shared; Roblox backend RenderRate defaults to 60 (0 = every frame); README + TODO.txt updated	2026-10-15 10:57:00 -05:00
4DBug	a1aa5cbb2d	Fix: long TextUnformatted (>2000 bytes) rendered each visible line to the end of the text (RenderText end was nil, upstream passes line_end); PushFont() saved the new font instead of the current one, so PopFont() never restored it (font preview leaked into all later text); t_fixes covers both	2026-10-15 10:54:56 -05:00
4DBug	dad1a0c0f1	Port leftovers: BringWindowToDisplayBehind, ImGuiSizeCallbackData + CalcWindowSizeAfterConstraint, ErrorCheckUsingSetCursorPosToExtendParentBoundaries, PopFocusScope user error (+ SetCurrentWindow stack sizes fix), log text decorations (Button/Menu/TreeNode/Drag/Slider/InputText/Checkbox/Radio), DataTypeFormatString display, ImGuiDataType S64/U64 (upstream enum layout; doubles), sscanf %u/length modifiers, mouse arrays sized ImGuiMouseButton.COUNT, AddCallback userdata copy; TODO.txt refreshed	2026-10-15 10:51:20 -05:00

4DBug	92dbd9a580	compare_upstream: skip IM_MSVC_RUNTIME_CHECKS_*/template<> when naming structs; [=] status for intentional Lua replacements (ImGuiStorage, ImStr*/ImFormatString*, allocators, C++ container internals, sizeof/ABI helpers...) with evidence regexes, reported separately	2026-10-15 09:39:17 -05:00
4DBug	e3840a938a	Port debug tools (item picker, flash style color, debug locate, DebugDraw*, keyboard preview, debug break, DrawCmd mesh view), context hooks, SetContextName, AddInputCharactersUTF8, sanity checks, window resize ids, Register/UnregisterUserTexture, SetPixelDensity, TestShortcutRouting, DemoMarker; InputTextState selection API (fixes undo crash, callbacks get 0-based positions), ShortcutsForCancel (Esc/right-click reverts drags/sliders), ImParseFormatSanitizeForPrinting, ImDrawList CloneOutput/PrimQuadUV/AddImageQuad, ImDrawData DeIndexAllBuffers/ScaleClipRects, internal helpers (ImBitVector, ImGuiPackedDate, inline ImGui getters...); t_debugtools, t_helpers	2026-10-15 08:52:30 -05:00

4DBug	f2c694bac5	Port ImTriangulator + upstream AddConcavePolyFilled (AA fringe, no per-triangle seams); [Luau] handles CCW winding and duplicate/collinear points that upstream mis-triangulates	2026-10-15 07:43:21 -05:00
4DBug	93a3c4faf5	Library draw call sites match 1.93: AddLineH/AddLineV + StrokeCenterBiased/StrokeInside (window/menu borders, separators, text cursor), tab border PathStroke, check mark AALineEnds, CloseButton/TreeNode lines/ColorButton/alpha checkerboard 1.93, Ctrl+Tab highlight AddRect arg order, metrics AA push/pop	2026-10-15 07:24:13 -05:00

4DBug	af2026113a	Draw list 1.93 strokes: _AddPolyline ported (texture AA lines, joins/miter/bevel, CapSquare, AALineEnds, Stroke Inside/Center/CenterBiased/Outside/Legacy), AddConvexPolyFilled AAFill, all primitives with 1.93 signatures/flags, PathRect/PathArcTo 1.93, baked line textures; Custom Rendering demo flags UI restored. check_all: t_pixels incremental==full redraw, headless screenshot (tools/test/shot.py)	2026-10-15 06:37:49 -05:00
4DBug	a111187591	Draw list 1.93 foundation (no output change): ImDrawFlags 1.93 values (Round*/Stroke*/AA*/JoinMiter/CapSquare/TextNoPixelSnap/UseTexForRoundCorners...; RoundCorners* kept as obsolete aliases), ImDrawList.Flags + PushDrawFlag/PopDrawFlag/_SetPixelDensity, SetupDrawListSharedData 1.93, style.CurveTessellationMaxError/AntiAliasedLineEnds, _AddPolyline entry point	2026-10-15 05:13:58 -05:00
4DBug	1e63710e33	compare_upstream: match XxxMT:Method and Class_Method globals to C++ class members (demo 100% ported by name)	2026-10-15 04:35:23 -05:00
4DBug	d18bc714fc	Demo: Selection State & Multi-Select section (ExampleSelectionWithDeletion, ExampleDualListBox, all 11 sub-demos) and Assets Browser ported; fix ImFloor() for negative non-integers (was floor-1)	2026-10-15 04:13:40 -05:00

4DBug	33ab5a1d84	Fix: InputTextMultiline crashed when drawn (InputTextLineIndexBuild/line offsets 0-based like upstream, inverted buf_display_end), InputText LiveEdit flag check; Shortcut()/IsKeyChordPressed() upstream defaults; FrameCount starts at 0 (IsWindowAppearing on first frame); missing ImGuiIO config fields with upstream defaults (+ ConfigDebugBeginReturnValueOnce/Loop); ColorButton drag source + ColorEdit4 drop target, IMGUI_PAYLOAD_TYPE_COLOR_3F/4F; t_fixes covers them	2026-10-15 03:03:10 -05:00
4DBug	9c8c1b018e	Demo: re-ported imgui_demo.cpp line by line in upstream order (one function per upstream function, same labels/HelpMarkers/comments, 176/186 IMGUI_DEMO_MARKERs; port table driver/Sub()/Demo* helpers removed, statics in S.<Function>). New: DemoWindowInputs (Inputs & Focus), Image Viewer, ShowExampleAppDockSpaceBasic. Selection/Assets Browser stubbed until multi-select is ported. ImColor helper (imgui_h.lua). PORT_STATUS demo similarity 29% -> 51%	2026-10-15 02:32:58 -05:00
4DBug	b929de5206	Fix: ImDrawList:PushClipRectFullScreen() was missing (drop target outside the window clip rect crashed); CalcItemSize() no longer writes to the caller's size (by value like upstream; fixes BeginTable UserOuterSize), scalar _CalcItemSizeXY for internal callers; t_fixes covers both	2026-10-15 02:05:43 -05:00
4DBug	ac4398ee2a	tools/test: check_all.sh (CI mirror + all scripted tests + demo forced open + LÖVE), hashes.sh (draw checksums vs a git rev), t_libhash (library-only draw checksum); regenerate PORT_STATUS	2026-10-15 02:03:40 -05:00

4DBug	4ac57cb571	Roblox backend: redraw budget is opt-in (SetRedrawBudget default 0 = every changed tile drawn the same frame)	2026-10-15 00:55:43 -05:00
4DBug	15dc766d82	bundle.py: build-time Luau optimizations (draw-data identical; IMGUI_BUNDLE_NOOPT=1 disables): hot library globals as bundle locals, enum/constant folding (values dumped by the luau CLI; IMGUI_BUNDLE_STRICT=1 in CI), --@hoist pure helpers to inlinable bundle-level local functions, statement IM_ASSERT -> assert; builtin type instead of ImGui._GetTypeFunc() alias (GETGLOBAL 15903 -> 540)	2026-10-15 00:23:20 -05:00
4DBug	ed53d0683e	Library perf (draw-data identical): layout core (no ImVec2 __index in ItemSize, inlined ID/style/clip stacks, scalar ItemAdd/IsClippedEx/CalcItemSize/GetColorU32), text + widgets (scalar TextEx/ButtonEx/Checkbox/Slider/Drag/Selectable/TreeNode, word-wrap memo), tables (in-place clip rects, no per-row/cell temporaries, @native cell functions, scalar ClipWith), draw list (PrimRectXY, scalar AddRect/AddRectFilled/AddLine/PathRect/arcs)	2026-10-14 23:27:23 -05:00

4DBug	090525076f	InputText: fix clipboard paste (filter was inverted, then off-by-one in the filtered buffer); ImParseFormatTrimDecorations: return [start, end) like upstream (Ctrl+click temp input showed decorations / crashed on "%d%%"); ShrinkWidths: tie order by Index descending like upstream; t_fixes test	2026-10-14 10:32:10 -05:00

4DBug	7eb7d5fcbb	Docking: set node.LastBgColor (closing dock hosts drew white bodies), host skips own bg, fix SetNextWindowBgAlpha; Roblox backend: frames skipped by the render rate cap are drawn later (UI could freeze when the app stopped rendering); t_dock_close test	2026-10-14 06:26:28 -05:00

4DBug	81c5ad9e43	Roblox backend: hidden TextBox proxy for text input ... A single off-screen TextBox holds focus while an imgui text field is active, so the OS delivers typing (any layout/unicode), paste and copy/cut. Its text mirrors imgui selection (fully selected) so Ctrl+C/X copy exactly that; deletions apply as an imgui Backspace; Ctrl is released around pasted characters. Focus is captured after the click is released, kept on clicks inside imgui, ends on clicks outside. KeyCode text kept as fallback. SetTextProxyDebug for logging.	2026-10-08 19:31:22 -05:00
