// USER IMPLEMENTATION
// This file contains compile-time options for ImGui.
// Other options (memory allocation overrides, callbacks, etc.) can be set at runtime via the ImGuiIO structure - ImGui::GetIO().
//-----------------------------------------------------------------------------

#pragma once

//---- Define your own ImVector<> type if you don't want to use the provided implementation defined in imgui.h
//#include <vector>
//#define ImVector  std::vector
//#define ImVector  MyVector

//---- Define assertion handler. Defaults to calling assert().
#include "global.h"
#define IM_ASSERT(_EXPR)  assert(_EXPR)

//---- Define attributes of all API symbols declarations, e.g. for DLL under Windows.
//#define IMGUI_API __declspec( dllexport )
//#define IMGUI_API __declspec( dllimport )

//---- Don't implement default handlers for Windows (so as not to link with OpenClipboard() and others Win32 functions)
//#define IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS
//#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS

//---- Include imgui_user.inl at the end of imgui.cpp so you can include code that extends ImGui using its private data/functions.
#define IMGUI_INCLUDE_IMGUI_USER_INL

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

//---- Define implicit cast operators to convert back<>forth from your math types and ImVec2/ImVec4.
#include <glm/vec2.hpp>
#define IM_VEC2_CLASS_EXTRA                                                \
        ImVec2(const glm::vec2& f) { x = f.x; y = f.y; }                   \
        operator glm::vec2() const { return glm::vec2(x, y); }

#include <glm/vec4.hpp>
#define IM_VEC4_CLASS_EXTRA                                                \
        ImVec4(const glm::vec4& f) { x = f.x; y = f.y; z = f.z; w = f.w; } \
        operator glm::vec4() const { return glm::vec4(x,y,z,w); }

//---- Freely implement extra functions within the ImGui:: namespace.
//---- Declare helpers or widgets implemented in imgui_user.inl or elsewhere, so end-user doesn't need to include multiple files.
//---- e.g. you can create variants of the ImGui::Value() helper for your low-level math types, or your own widgets/helpers.
