//-----------------------------------------------------------------------------
// COMPILE-TIME OPTIONS FOR DEAR IMGUI
// 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 files 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. 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.

//---- Don't define obsolete functions/enums/behaviors. Consider enabling from time to time after updating to avoid
//using soon-to-be obsolete function/names. #define IMGUI_DISABLE_OBSOLETE_FUNCTIONS

//---- Disable all of Dear ImGui or don't implement standard windows.
// It is very strongly recommended to NOT disable the demo windows during development. Please read comments in
// imgui_demo.cpp.
//#define IMGUI_DISABLE                                     // Disable everything: all headers and source files will be

//ShowDemoWindow()/ShowStyleEditor() will be empty. Not recommended. #define IMGUI_DISABLE_METRICS_WINDOW // Disable
//metrics/debugger window: ShowMetricsWindow() will be empty.

//---- Don't implement some functions to reduce linkage requirements.
//#define IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS   // [Win32] Don't implement default clipboard handler. Won't
//use and link with OpenClipboard/GetClipboardData/CloseClipboard etc. (user32.lib/.a, kernel32.lib/.a) #define

//Implement default OSX clipboard handler (need to link with '-framework ApplicationServices', this is why this is not
//the default). #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

//ImFileHandle at all (replace them with dummies) #define IMGUI_DISABLE_DEFAULT_FILE_FUNCTIONS              // Don't
//implement ImFileOpen/ImFileClose/ImFileRead/ImFileWrite and ImFileHandle so you can implement them yourself if you
//don't want to link with fopen/fclose/fread/fwrite. This will also disable the LogToTTY() function. #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(). #define IMGUI_DISABLE_SSE // Disable
//use of SSE intrinsics even if available

//---- Include imgui_user.h at the end of imgui.h as a convenience
//#define IMGUI_INCLUDE_IMGUI_USER_H

//---- Pack colors to BGRA8 instead of RGBA8 (to avoid converting from one to another)
//#define IMGUI_USE_BGRA_PACKED_COLOR

//---- Use 32-bit for ImWchar (default is 16-bit) to support unicode planes 1-16. (e.g. point beyond 0xFFFF like
//emoticons, dingbats, symbols, shapes, ancient languages, etc...) #define IMGUI_USE_WCHAR32

//---- Avoid multiple STB libraries implementations, or redefine path/filenames to prioritize another version
// By default the embedded implementations are declared static and not available outside of Dear ImGui sources files.

//#define IMGUI_DISABLE_STB_RECT_PACK_IMPLEMENTATION

//---- Use stb_printf's faster implementation of vsnprintf instead of the one from libc (unless
//IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS is defined)
// Requires 'stb_sprintf.h' to be available in the include path. 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. #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 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;
// typedef void (*MyImDrawCallback)(const ImDrawList* draw_list, const ImDrawCmd* cmd, void* my_renderer_user_data);
//#define ImDrawCallback MyImDrawCallback

//---- Debug Tools: Macro to break in Debugger
// (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()

//---- Debug Tools: Have the Item Picker break in the ItemAdd() function instead of ItemHoverable(),
// (which comes earlier in the code, will catch a few extra items, allow picking items other than Hovered one.)
// This adds a small runtime cost which is why it is not enabled by default.
//#define IMGUI_DEBUG_TOOL_ITEM_PICKER_EX

//---- Debug Tools: Enable slower asserts
//#define IMGUI_DEBUG_PARANOID

//---- Tip: You can add extra functions within the ImGui:: namespace, here or in your own headers files.
