4DBug 9be05aeb5c Fonts: ImFontGlyphRangesBuilder + GetGlyphRangesDefault, ImFont:CalcWordWrapPosition, stb_decompress + Decode85 + AddFontFromMemoryCompressed(Base85)TTF, atlas helpers (RemoveFont, RemoveCustomRect, AddRemapCodepoint (remap never triggered before), IsGlyphRangeUnused, texture status/format names...); t_fonts 2026-10-15 08:05:51 -05:00

4DBug 9872d43fd6 Draw list 1.93: baked round corners in the font atlas (ImFontAtlasBuildUpdateTexDataCorners, fill radii 1..16 + 3 stroke thicknesses) used by AddRect/AddRectFilled when pixel-aligned (_AddRectBaked/_AddRectFilledBaked) 2026-10-15 06:55:57 -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 049e160852 Port multi-select, box-select and typing-select (BeginMultiSelect/EndMultiSelect, SetNextItemSelectionUserData, MultiSelectItemHeader/Footer, BeginBoxSelect/EndBoxSelect, GetTypingSelectRequest/TypingSelectFind*, ImGuiSelectionBasicStorage/ExternalStorage, Metrics nodes); wired into Selectable/Checkbox/TreeNode/clipper/tables; t_multiselect 2026-10-15 03:49:53 -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 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 b71e29ee35 Roblox backend perf (pixel-identical): redraw budget (SetRedrawBudget, default 1.5 ms; RenderRate default 0), exact in-place draw list compare + whole-pixel move fast path, partial tile redraws, flat rects hashed by in-tile rect, quads hashed by TL/BR, no full redraw on texture updates, @native CopyTexturePixels, reused partial upload buffers; imgui_draw: @native word wrap, ImStrByte/classifier inlined, text size cache covers wrapped text; t_pixels pixel oracle; run.py RUN_FLAGS 2026-10-14 22:26:38 -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 e502866075 CI: minified builds (ImGui.min.luau, ImGui-nodemo.min.luau, imgui_love.min.lua, imgui_love-nodemo.min.lua) via tools/minify.py; checks + release assets; run.py MINIFY=1 2026-10-14 10:23:55 -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 e228ed8638 Roblox backend: text proxy is opt-in (SetTextProxy), remove SetTextProxyDebug; new example main.client.luau 2026-10-09 02:22:30 -05:00
4DBug 14e6da3b29 SetNextWindowCached(key): opt-in cached windows on top of the refresh policy (skip contents while idle), t_cached_window test, README snippet

4DBug 66fa061089 LÖVE backend + build target (compat/luajit.lua shims, Roblox build unchanged), examples/example_love, examples/example_shared (same app on Roblox and LÖVE), LuaJIT checksum tests 2026-10-08 19:31:22 -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.
