// DEAR IMGUI COMPILE-TIME OPTIONS

// Runtime options (clipboard callbacks, enabling various features, etc.) can generally be set via the ImGuiIO structure.

// You can use ImGui::SetAllocatorFunctions() before calling ImGui::CreateContext() to rewire memory allocation functions.

//-----------------------------------------------------------------------------

// A) You may edit imconfig.h (and not overwrite it when updating Dear ImGui, or maintain a patch/rebased branch with your modifications to it)

// B) or '#define IMGUI_USER_CONFIG "my_imgui_config.h"' in your project and then add directives in your own file without touching this template.

//-----------------------------------------------------------------------------

// You need to make sure that configuration settings are defined consistently _everywhere_ Dear ImGui is used, which include the imgui*.cpp

// files but also _any_ of your code that uses Dear ImGui. This is because some compile-time options have an affect on data structures.

// Defining those options in imconfig.h will ensure every compilation unit gets to see the same data structure layouts.

// Call IMGUI_CHECKVERSION() from your .cpp file to verify that the data structures your files are using are matching the ones imgui.cpp is using.

//-----------------------------------------------------------------------------

//---- Define assertion handler. Defaults to calling assert().

// If your macro uses multiple statements, make sure is enclosed in a 'do { .. } while (0)' block so it can be used as a single statement.

//#define IM_ASSERT(_EXPR)  MyAssert(_EXPR)

//#define IM_ASSERT(_EXPR)  ((void)(_EXPR))     // Disable asserts

//---- Define attributes of all API symbols declarations, e.g. for DLL under Windows

// Using Dear ImGui via a shared library is not recommended, because of function call overhead and because we don't guarantee backward nor forward ABI compatibility.

// - Windows DLL users: heaps and globals are not shared across DLL boundaries! You will need to call SetCurrentContext() + SetAllocatorFunctions()

//   for each static/DLL boundary you are calling from. Read "Context and Memory Allocators" section of imgui.cpp for more details.

//#define IMGUI_API __declspec(dllexport)                   // MSVC Windows: DLL export

//#define IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS            // Don't implement ImFormatString/ImFormatStringV so you can implement them yourself (e.g. if you don't want to link with vsnprintf)

//#define IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS              // Don't implement ImFabs/ImSqrt/ImPow/ImFmod/ImCos/ImSin/ImAcos/ImAtan2 so you can implement them yourself.

//#define IMGUI_DISABLE_DEFAULT_ALLOCATORS                  // Don't implement default allocators calling malloc()/free() to avoid linking with them. You will need to call ImGui::SetAllocatorFunctions().

//---- Use stb_sprintf.h for a faster implementation of vsnprintf instead of the one from libc (unless IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS is defined)

// Compatibility checks of arguments and formats done by clang and GCC will be disabled in order to support the extra formats provided by stb_sprintf.h.

//#define IMGUI_USE_STB_SPRINTF

//---- Use FreeType to build and rasterize the font atlas (instead of stb_truetype which is embedded by default in Dear ImGui)

// Requires FreeType headers to be available in the include path. Requires program to be compiled with 'misc/freetype/imgui_freetype.cpp' (in this repository) + the FreeType library (not provided).

// On Windows you may use vcpkg with 'vcpkg install freetype --triplet=x64-windows' + 'vcpkg integrate install'.

//#define IMGUI_ENABLE_FREETYPE

//---- Use FreeType + plutosvg or lunasvg to render OpenType SVG fonts (SVGinOT)

// Only works in combination with IMGUI_ENABLE_FREETYPE.

// - lunasvg is currently easier to acquire/install, as e.g. it is part of vcpkg.

// - plutosvg will support more fonts and may load them faster. It currently requires to be built manually but it is fairly easy. See misc/freetype/README for instructions.

// - Both require headers to be available in the include path + program to be linked with the library code (not provided).

// - (note: lunasvg implementation is based on Freetype's rsvg-port.c which is licensed under CeCILL-C Free Software License Agreement)

//#define IMGUI_ENABLE_FREETYPE_PLUTOSVG

//#define IMGUI_ENABLE_FREETYPE_LUNASVG

//---- Use stb_truetype to build and rasterize the font atlas (default)

// The only purpose of this define is if you want force compilation of the stb_truetype backend ALONG with the FreeType backend.

//#define IMGUI_ENABLE_STB_TRUETYPE

//---- Define constructor and implicit cast operators to convert back<>forth between your math types and ImVec2/ImVec4.

// This will be inlined as part of ImVec2 and ImVec4 class declarations.

//---- Use 32-bit vertex indices (default is 16-bit) is one way to allow large meshes with more than 64K vertices.

// Your renderer backend will need to support it (most example renderer backends support both 16/32-bit indices).

// Another way to allow large meshes while keeping 16-bit indices is to handle ImDrawCmd::VtxOffset in your renderer.

// Read about ImGuiBackendFlags_RendererHasVtxOffset for details.

//#define ImDrawIdx unsigned int

//---- Override ImDrawCallback signature (will need to modify renderer backends accordingly)

//struct ImDrawList;

//struct ImDrawCmd;

// (use 'Metrics->Tools->Item Picker' to pick widgets with the mouse and break into them for easy debugging.)

//#define IM_DEBUG_BREAK  IM_ASSERT(0)

//#define IM_DEBUG_BREAK  __debugbreak()
