imgui-luau

t_apps.luau

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%

2026-10-08 20:43:56 -05:00

t_click_fuzz.luau

demo: port all Widgets sections, ShowStyleEditor/ShowStyleSelector, menus; fix crashes found by click fuzzer (color/scalar default args, InputTextWithHint string hint, AddText overload, splitter reset, CollapsingHeader close button, callback data methods, SetKeyboardFocusHere & misc getters)

2026-10-08 08:06:00 -05:00

2026-10-15 09:39:17 -05:00

t_dock_close.luau

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

2026-10-08 12:11:36 -05:00

t_fixes.luau

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

2026-10-15 10:51:20 -05:00

t_libhash.luau

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

t_nodemo.luau

Reorganize like upstream: library at root (docking/dragdrop/debug tools merged into imgui.lua, tabs into imgui_widgets.lua), single imgui_demo.lua, backends/, fonts/, examples/, docs/; --no-demo build

Port window hit-test hole so PassthruCentralNode doesn't capture the mouse

2026-10-08 09:15:32 -05:00

t_pixels.luau

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
