v1.92.600

Based on ImGui v1.92.6 & hello_imgui v1.92.6.

Dear ImGui Explorer

Dear ImGui Explorer (formerly "imgui_manual") has been rewritten from scratch and integrated into the Dear ImGui Bundle repository. It was previously a standalone project; Dear ImGui Bundle is now its parent repository.

It provides interactive manuals for ImGui, ImPlot, ImPlot3D, and ImAnim — with side-by-side C++/Python code, syntax highlighting, and search in API reference files (headers, Python stubs).

• Follow source: click on any demo widget to jump to its source code
• Search across API files with Ctrl+Shift+F
• Lazy-load demo code files (desktop and Emscripten)
• Deployed at pthom.github.io/imgui_explorer

Dear ImGui Bundle Explorer (formerly "ImGui Bundle Interactive Manual")

The interactive manual has been renamed to Dear ImGui Bundle Explorer and significantly enhanced:

• New intro tab with a carousel of 7 interactive slides showcasing the ecosystem
• Deployed at traineq.org/imgui_bundle_explorer

New library: ImAnim

Added ImAnim, a tweening and animation library for ImGui.

• Available via immapp.run(..., with_im_anim=True) / ImmApp::AddOnParams::withImAnim
• Python API adapted for get_float, get_vec2, get_color, etc.

Updates to libraries

• Update imgui to v1.92.6-docking
• Update hello_imgui to v1.92.6
• Update implot to latest version (breaking change: added ImPlotSpec, removed plot item styling)
• Update implot3d to latest version (breaking change: added ImPlot3DSpec)
• Update ImGuiColorTextEdit: line numbers always visible in separate gutter, improved selection colors
• Update imgui_knobs: added SetKnobColors, UnsetKnobColors, default color adapts to light/dark theme
• Update imgui_md: render tables using ImGui tables (resizable columns), delay before showing link hrefs

Python: Async run and notebook support

• Added hello_imgui.run_async() / immapp.run_async() for async/await support (with maximal performance). See doc for async
• Added immapp.nb module for non-blocking Jupyter notebook execution (nb.start(), nb.stop(), nb.is_running()). See doc for notebook
• Added hello_imgui.nb convenience module

Pyodide (web) support

• Added Docker build system for Pyodide wheels
• run() is fire-and-forget in Pyodide; use run_async() for awaitable behavior
• CI workflow for Pyodide builds
• Pyodide wheels now exclude demo code to reduce size

Python bindings

• Added em_size() and em_to_vec2() at root of imgui_bundle for DPI-independent sizing
• Added __getitem__ / __setitem__ (subscript []) for ImVec2 and ImVec4
• Configurable wheel builds with selective module inclusion
• Fix: accept read-only numpy arrays (e.g. from pandas) in nanobind bindings

hello_imgui improvements

• Added AddAssetsSearchPath() / ClearAssetsSearchPaths() / GetAssetsSearchPaths() for multi-folder asset resolution at runtime
• Added topMost window attribute
• Added iniDisable and iniClearPreviousSettings params
• Added FpsIdling::vsyncToMonitor and FpsIdling::fpsMax settings
• Added theme_changed callback
• Fix: ManualRender RunnerParams lifetime management

Build & CI

• Added ARM Linux (aarch64) wheel builds using native ubuntu-24.04-arm runners
• Reduced Emscripten .data sizes: demos only bundle the assets they actually need
• Deduplicated demo assets (removed ~1.1M of files duplicated between assets/ and demos_assets/)
• Emscripten: use GLFW3 backend by default instead of SDL2
• Fix: shell injection in BrowseToUrl (replaced system() with fork+execlp)

Documentation

• Complete documentation overhaul using Jupyter Book, available as PDF
• Added developer documentation (building, bindings, repo structure)
