Add .github/workflows/deploy-wasm.yml that: - Installs Emscripten SDK on ubuntu-latest - Builds example_sdl2_opengl3 with Makefile.emscripten using -sSINGLE_FILE (all WASM+JS embedded in a single .html file, no separate .wasm/.js) - Uses custom shell_imgui_xl.html with loading spinner and WebGL context loss handling - Deploys to gh-pages/wasm/ directory via peaceiris/actions-gh-pages The resulting live demo at turtle-pb.github.io/imgui_xl/wasm/index.html will show the ACTUAL Dear ImGui demo window running in the browser via WebAssembly — not a canvas simulation, but real compiled C++ ImGui. Triggers on pushes to master that touch ImGui source files, the SDL2/ OpenGL3 backend, the example, or the shell template. Also supports manual workflow_dispatch.
New to Dear ImGui? - Check out the Getting Started guide: https://github.com/ocornut/imgui/wiki/Getting-Started - About Backends: docs/BACKENDS.md file, or on the web: https://github.com/ocornut/imgui/blob/master/docs/BACKENDS.md - About Examples: docs/EXAMPLES.md file, or on the web: https://github.com/ocornut/imgui/blob/master/docs/EXAMPLES.md Backends = Helper code to facilitate integration with platforms/graphics api (used by Examples + should be used by your app). Examples = Standalone applications showcasing integration with platforms/graphics api. A few Examples have extra README files in their respective directory, please check them too! Once Dear ImGui is running (in either examples or your own application/game/engine), run and refer to ImGui::ShowDemoWindow() in imgui_demo.cpp for the end-user API.
