See EXAMPLES and BACKENDS files in the docs/ folder.
See BACKENDS and EXAMPLES files in the docs/ folder, or on the web at: https://github.com/ocornut/imgui/tree/master/docs
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.
Some 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.

This example shows how to integrate Dear ImGui with Metal. It is based on the "cross-platform" game template provided with Xcode as of Xcode 9.
Consider basing your work off the example_glfw_metal/ or example_sdl_metal/ examples. They are better supported and will be portable unlike this one.

## How to Build
- You need to install Emscripten from https://emscripten.org/docs/getting_started/downloads.html, and have the environment variables set, as described in https://emscripten.org/docs/getting_started/downloads.html#installation-instructions
- You may also refer to our [Continuous Integration setup](https://github.com/ocornut/imgui/tree/master/.github/workflows) for Emscripten setup.
- Depending on your configuration, in Windows you may need to run `emsdk/emsdk_env.bat` in your console to access the Emscripten command-line tools.
- Then build using `make` while in the `example_emscripten_opengl3/` directory.
## How to Run
To run on a local machine:
- `make serve` will use Python3 to spawn a local webserver, you can then browse http://localhost:8000 to access your build.
- Otherwise, generally you will need a local webserver:
- Quoting [https://emscripten.org/docs/getting_started](https://emscripten.org/docs/getting_started/Tutorial.html#generating-html):<br>
_"Unfortunately several browsers (including Chrome, Safari, and Internet Explorer) do not support file:// [XHR](https://emscripten.org/docs/site/glossary.html#term-xhr) requests, and can’t load extra files needed by the HTML (like a .wasm file, or packaged file data as mentioned lower down). For these browsers you’ll need to serve the files using a [local webserver](https://emscripten.org/docs/getting_started/FAQ.html#faq-local-webserver) and then open http://localhost:8000/hello.html."_
- Emscripten SDK has a handy `emrun` command: `emrun web/example_emscripten_opengl3.html --browser firefox` which will spawn a temporary local webserver (in Firefox). See https://emscripten.org/docs/compiling/Running-html-files-with-emrun.html for details.
- You may use Python 3 builtin webserver: `python -m http.server -d web` (this is what `make serve` uses).
- You may use Python 2 builtin webserver: `cd web && python -m SimpleHTTPServer`.
## Obsolete features:
- Emscripten 2.0 (August 2020) obsoleted the fastcomp backend, only llvm is supported.
- Emscripten 1.39.0 (October 2019) obsoleted the `BINARYEN_TRAP_MODE=clamp` compilation flag which was required with version older than 1.39.0 to avoid rendering artefacts. See [#2877](https://github.com/ocornut/imgui/issues/2877) for details. If you use an older version, uncomment this line in the Makefile: `#EMS += -s BINARYEN_TRAP_MODE=clamp`

# How to Build
## How to Build
- You need to install Emscripten from https://emscripten.org/docs/getting_started/downloads.html, and have the environment variables set, as described in https://emscripten.org/docs/getting_started/downloads.html#installation-instructions
- Depending on your configuration, in Windows you may need to run `emsdk/emsdk_env.bat` in your console to access the Emscripten command-line tools.
- Then build using `make` while in the `example_emscripten_wgpu/` directory.
- You may also refer to our [Continuous Integration setup](https://github.com/ocornut/imgui/tree/master/.github/workflows) for Emscripten setup.
- Requires Emscripten 2.0.10 (December 2020) due to GLFW adaptations
- Then build using `make -f Makefile.emscripten` while in the `example_emscripten_wgpu/` directory.
- Requires recent Emscripten as WGPU is still a work-in-progress API.
## How to Run
To run on a local machine:
- Make sure your browse supports WGPU and it is enabled. WGPU is still WIP not enabled by default in most browser.
- `make serve` will use Python3 to spawn a local webserver, you can then browse http://localhost:8000 to access your build.
- Otherwise, generally you will need a local webserver:
- Quoting [https://emscripten.org/docs/getting_started](https://emscripten.org/docs/getting_started/Tutorial.html#generating-html):<br>
_"Unfortunately several browsers (including Chrome, Safari, and Internet Explorer) do not support file:// [XHR](https://emscripten.org/docs/site/glossary.html#term-xhr) requests, and can’t load extra files needed by the HTML (like a .wasm file, or packaged file data as mentioned lower down). For these browsers you’ll need to serve the files using a [local webserver](https://emscripten.org/docs/getting_started/FAQ.html#faq-local-webserver) and then open http://localhost:8000/hello.html."_
- Emscripten SDK has a handy `emrun` command: `emrun web/example_emscripten_opengl3.html --browser firefox` which will spawn a temporary local webserver (in Firefox). See https://emscripten.org/docs/compiling/Running-html-files-with-emrun.html for details.
- You may use Python 3 builtin webserver: `python -m http.server -d web` (this is what `make serve` uses).
- You may use Python 2 builtin webserver: `cd web && python -m SimpleHTTPServer`.
- If you are accessing the files over a network, certain browsers, such as Firefox, will restrict Gamepad API access to secure contexts only (e.g. https only).

# How to Build
## Windows with Visual Studio's IDE
Use the provided project file (.vcxproj). Add to solution (imgui_examples.sln) if necessary.
## Windows with Visual Studio's CLI
Use build_win32.bat or directly:
```
set SDL2_DIR=path_to_your_sdl2_folder
cl /Zi /MD /utf-8 /I.. /I..\.. /I%SDL2_DIR%\include main.cpp ..\..\backends\imgui_impl_sdl2.cpp ..\..\backends\imgui_impl_opengl3.cpp ..\..\imgui*.cpp /FeDebug/example_sdl2_opengl3.exe /FoDebug/ /link /libpath:%SDL2_DIR%\lib\x86 SDL2.lib SDL2main.lib opengl32.lib /subsystem:console
# ^^ include paths ^^ source files ^^ output exe ^^ output dir ^^ libraries
# or for 64-bit:
cl /Zi /MD /utf-8 /I.. /I..\.. /I%SDL2_DIR%\include main.cpp ..\..\backends\imgui_impl_sdl2.cpp ..\..\backends\imgui_impl_opengl3.cpp ..\..\imgui*.cpp /FeDebug/example_sdl2_opengl3.exe /FoDebug/ /link /libpath:%SDL2_DIR%\lib\x64 SDL2.lib SDL2main.lib opengl32.lib /subsystem:console
```
## Linux and similar Unixes
Use our Makefile or directly:
```
c++ `sdl2-config --cflags` -I .. -I ../.. -I ../../backends
main.cpp ../../backends/imgui_impl_sdl2.cpp ../../backends/imgui_impl_opengl3.cpp ../../imgui*.cpp
`sdl2-config --libs` -lGL -ldl
```
## macOS
Use our Makefile or directly:
```
brew install sdl2
c++ `sdl2-config --cflags` -I .. -I ../.. -I ../../backends
main.cpp ../../backends/imgui_impl_sdl2.cpp ../../backends/imgui_impl_opengl3.cpp ../../imgui*.cpp
`sdl2-config --libs` -framework OpenGl -framework CoreFoundation
```
## Emscripten
**Building**
You need to install Emscripten from https://emscripten.org/docs/getting_started/downloads.html, and have the environment variables set, as described in https://emscripten.org/docs/getting_started/downloads.html#installation-instructions
- Depending on your configuration, in Windows you may need to run `emsdk/emsdk_env.bat` in your console to access the Emscripten command-line tools.
- You may also refer to our [Continuous Integration setup](https://github.com/ocornut/imgui/tree/master/.github/workflows) for Emscripten setup.
- Then build using `make -f Makefile.emscripten` while in the current directory.
**Running an Emscripten project**
To run on a local machine:
- `make -f Makefile.emscripten serve` will use Python3 to spawn a local webserver, you can then browse http://localhost:8000 to access your build.
- Otherwise, generally you will need a local webserver. Quoting [https://emscripten.org/docs/getting_started](https://emscripten.org/docs/getting_started/Tutorial.html#generating-html):<br>
_"Unfortunately several browsers (including Chrome, Safari, and Internet Explorer) do not support file:// [XHR](https://emscripten.org/docs/site/glossary.html#term-xhr) requests, and can’t load extra files needed by the HTML (like a .wasm file, or packaged file data as mentioned lower down). For these browsers you’ll need to serve the files using a [local webserver](https://emscripten.org/docs/getting_started/FAQ.html#faq-local-webserver) and then open http://localhost:8000/hello.html."_
- Emscripten SDK has a handy `emrun` command: `emrun web/index.html --browser firefox` which will spawn a temporary local webserver (in Firefox). See https://emscripten.org/docs/compiling/Running-html-files-with-emrun.html for details.
- You may use Python 3 builtin webserver: `python -m http.server -d web` (this is what `make serve` uses).
- You may use Python 2 builtin webserver: `cd web && python -m SimpleHTTPServer`.
- If you are accessing the files over a network, certain browsers, such as Firefox, will restrict Gamepad API access to secure contexts only (e.g. https only).

// - If the file cannot be loaded, the function will return a nullptr. Please handle those errors in your application (e.g. use an assertion, or display an error and quit).
// - The fonts will be rasterized at a given size (w/ oversampling) and stored into a texture when calling ImFontAtlas::Build()/GetTexDataAsXXXX(), which ImGui_ImplXXXX_NewFrame below will call.
// - Use '#define IMGUI_ENABLE_FREETYPE' in your imconfig file to use Freetype for higher quality font rendering.

# How to Build
## Windows with Visual Studio's IDE
Use the provided project file (.vcxproj). Add to solution (imgui_examples.sln) if necessary.
## Windows with Visual Studio's CLI
Use build_win32.bat or directly:
```
set SDL2_DIR=path_to_your_sdl3_folder
cl /Zi /MD /utf-8 /I.. /I..\.. /I%SDL2_DIR%\include main.cpp ..\..\backends\imgui_impl_sdl3.cpp ..\..\backends\imgui_impl_opengl3.cpp ..\..\imgui*.cpp /FeDebug/example_sdl3_opengl3.exe /FoDebug/ /link /libpath:%SDL2_DIR%\lib\x86 SDL3.lib opengl32.lib /subsystem:console
# ^^ include paths ^^ source files ^^ output exe ^^ output dir ^^ libraries
# or for 64-bit:
cl /Zi /MD /utf-8 /I.. /I..\.. /I%SDL2_DIR%\include main.cpp ..\..\backends\imgui_impl_sdl3.cpp ..\..\backends\imgui_impl_opengl3.cpp ..\..\imgui*.cpp /FeDebug/example_sdl3_opengl3.exe /FoDebug/ /link /libpath:%SDL2_DIR%\lib\x64 SDL3.lib SDL2mainopengl32.lib /subsystem:console
```
## Linux and similar Unixes
Use our Makefile or directly:
```
c++ `sdl3-config --cflags` -I .. -I ../.. -I ../../backends
main.cpp ../../backends/imgui_impl_sdl3.cpp ../../backends/imgui_impl_opengl3.cpp ../../imgui*.cpp
`sdl3-config --libs` -lGL -ldl
```
## macOS
Use our Makefile or directly:
```
brew install sdl3
c++ `sdl3-config --cflags` -I .. -I ../.. -I ../../backends
main.cpp ../../backends/imgui_impl_sdl3.cpp ../../backends/imgui_impl_opengl3.cpp ../../imgui*.cpp
`sdl3-config --libs` -framework OpenGl -framework CoreFoundation
```
## Emscripten
As of 2023-05-30 Emscripten doesn't support SDL3 yet.

// Dear ImGui: standalone example application for SDL3 + SDL_Renderer

// - FAQ https://dearimgui.com/faq
// - Getting Started https://dearimgui.com/getting-started
// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).
// - Introduction, links and more at the top of imgui.cpp
// Important to understand: SDL_Renderer is an _optional_ component of SDL3.
// For a multi-platform app consider using e.g. SDL+DirectX on Windows and SDL+OpenGL on Linux/OSX.

// - If no fonts are loaded, dear imgui will use the default font. You can also load multiple fonts and use ImGui::PushFont()/PopFont() to select them.

// - If the file cannot be loaded, the function will return a nullptr. Please handle those errors in your application (e.g. use an assertion, or display an error and quit).
// - The fonts will be rasterized at a given size (w/ oversampling) and stored into a texture when calling ImFontAtlas::Build()/GetTexDataAsXXXX(), which ImGui_ImplXXXX_NewFrame below will call.
// - Use '#define IMGUI_ENABLE_FREETYPE' in your imconfig file to use Freetype for higher quality font rendering.
// - Read 'docs/FONTS.md' for more instructions and details.
// - Remember that in C/C++ if you want to include a backslash \ in a string literal you need to write a double backslash \\ !
