//-----------------------------------------------------------------------------
// 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.
//-----------------------------------------------------------------------------
#pragma once
//---- 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_DISABLE_DEFAULT_SHELL_FUNCTIONS // Don't implement default platform_io.Platform_OpenInShellFn() handler (Win32: ShellExecute(), require shell32.lib/.a, Mac/Linux: use system("")).
//#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_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_DEFAULT_FONT // Disable default embedded font (ProggyClean.ttf), remove ~9.5 KB from output binary. AddFontDefault() will assert.
//#define IMGUI_DISABLE_SSE // Disable use of SSE intrinsics even if available
//---- Enable Test Engine / Automation features.
//#define IMGUI_ENABLE_TEST_ENGINE // Enable imgui_test_engine hooks. Generally set automatically by include "imgui_te_config.h", see Test Engine for details.
//---- Include imgui_user.h at the end of imgui.h as a convenience

// 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.
// - plutosvg is currently easier to install, as e.g. it is part of vcpkg. It will support more fonts and may load them faster. 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).

//#define IMGUI_ENABLE_FREETYPE_PLUTOSVG
//#define IMGUI_ENABLE_FREETYPE_LUNASVG
//---- Use stb_truetype to build and rasterize the font atlas (default)

//---- ...Or use Dear ImGui's own very basic math operators.
//#define IMGUI_DEFINE_MATH_OPERATORS
//---- 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.

// (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()

// dear imgui: Platform Backend for GLFW
// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan, WebGPU..)
// (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
// (Requires: GLFW 3.1+. Prefer GLFW 3.3+ for full feature support.)
// Implemented features:
// [X] Platform: Clipboard support.
// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen (Windows only).
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy GLFW_KEY_* values are obsolete since 1.87 and not supported since 1.91.5]
// [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
// [X] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors). Resizing cursors requires GLFW 3.4+! Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
// [X] Platform: Multi-viewport support (multiple windows). Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
// Missing features or Issues:
// [ ] Touch events are only correctly identified as Touch on Windows. This create issues with some interactions. GLFW doesn't provide a way to identify touch inputs from mouse inputs, we cannot call io.AddMouseSourceEvent() to identify the source. We provide a Windows-specific workaround.
// [ ] Missing ImGuiMouseCursor_Wait and ImGuiMouseCursor_Progress cursors.
// [ ] Multi-viewport: ParentViewportID not honored, and so io.ConfigViewportsNoDefaultParent has no effect (minor).
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.

// dear imgui: Renderer Backend for modern OpenGL with shaders / programmatic pipeline
// - Desktop GL: 2.x 3.x 4.x
// - Embedded GL: ES 2.0 (WebGL 1.0), ES 3.0 (WebGL 2.0)
// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
// Implemented features:
// [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
// [x] Renderer: Large meshes support (64k+ vertices) even with 16-bit indices (ImGuiBackendFlags_RendererHasVtxOffset) [Desktop OpenGL only!]
// [X] Renderer: Multi-viewport support (multiple windows). Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
// About WebGL/ES:
// - You need to '#define IMGUI_IMPL_OPENGL_ES2' or '#define IMGUI_IMPL_OPENGL_ES3' to use WebGL or OpenGL ES.
// - This is done automatically on iOS, Android and Emscripten targets.
// - For other targets, the define needs to be visible from the imgui_impl_opengl3.cpp compilation unit. If unsure, define globally or in imconfig.h.

//-----------------------------------------------------------------------------
// About imgui_impl_opengl3_loader.h:
//
// We embed our own OpenGL loader to not require user to provide their own or to have to use ours,
// which proved to be endless problems for users.
// Our loader is custom-generated, based on gl3w but automatically filtered to only include
// enums/functions that we use in our imgui_impl_opengl3.cpp source file in order to be small.
//
// YOU SHOULD NOT NEED TO INCLUDE/USE THIS DIRECTLY. THIS IS USED BY imgui_impl_opengl3.cpp ONLY.
// THE REST OF YOUR APP SHOULD USE A DIFFERENT GL LOADER: ANY GL LOADER OF YOUR CHOICE.
//
// IF YOU GET BUILD ERRORS IN THIS FILE (commonly macro redefinitions or function redefinitions):
// IT LIKELY MEANS THAT YOU ARE BUILDING 'imgui_impl_opengl3.cpp' OR INCLUDING 'imgui_impl_opengl3_loader.h'
// IN THE SAME COMPILATION UNIT AS ONE OF YOUR FILE WHICH IS USING A THIRD-PARTY OPENGL LOADER.
// (e.g. COULD HAPPEN IF YOU ARE DOING A UNITY/JUMBO BUILD, OR INCLUDING .CPP FILES FROM OTHERS)
// YOU SHOULD NOT BUILD BOTH IN THE SAME COMPILATION UNIT.
// BUT IF YOU REALLY WANT TO, you can '#define IMGUI_IMPL_OPENGL_LOADER_CUSTOM' and imgui_impl_opengl3.cpp
// WILL NOT BE USING OUR LOADER, AND INSTEAD EXPECT ANOTHER/YOUR LOADER TO BE AVAILABLE IN THE COMPILATION UNIT.
//

// dear imgui: Platform Backend for Windows (standard windows API for 32-bits AND 64-bits applications)
// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..)
// Implemented features:
// [X] Platform: Clipboard support (for Win32 this is actually part of core dear imgui)
// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen.
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy VK_* values are obsolete since 1.87 and not supported since 1.91.5]
// [X] Platform: Gamepad support.
// [X] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors). Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
// [X] Platform: Multi-viewport support (multiple windows). Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.

// Grep for [DEAR IMGUI] to find the changes.
//
// stb_rect_pack.h - v1.01 - public domain - rectangle packing
// Sean Barrett 2014
//
// Useful for e.g. packing rectangular textures into an atlas.
// Does not do rotation.
//
// Before #including,
//
// #define STB_RECT_PACK_IMPLEMENTATION
//
// in the file that you want to have the implementation.
//
// Not necessarily the awesomest packing method, but better than
// the totally naive one in stb_truetype (which is primarily what
// this is meant to replace).
//
// Has only had a few tests run, may have issues.
//
// More docs to come.
//
// No memory allocations; uses qsort() and assert() from stdlib.
// Can override those by defining STBRP_SORT and STBRP_ASSERT.
//
// This library currently uses the Skyline Bottom-Left algorithm.
//
// Please note: better rectangle packers are welcome! Please
// implement them to the same API, but with a different init
// function.

// Mini memory editor for Dear ImGui (to embed in your game/tools)
// Get latest version at http://www.github.com/ocornut/imgui_club
// Licensed under The MIT License (MIT)
// Right-click anywhere to access the Options menu!
// You can adjust the keyboard repeat delay/rate in ImGuiIO.
// The code assume a mono-space font for simplicity!
// If you don't use the default font, use ImGui::PushFont()/PopFont() to switch to a mono-space font before calling this.
//
// Usage:
// // Create a window and draw memory editor inside it:
// static MemoryEditor mem_edit_1;
// static char data[0x10000];
// size_t data_size = 0x10000;
// mem_edit_1.DrawWindow("Memory Editor", data, data_size);
//
// Usage:
// // If you already have a window, use DrawContents() instead:
// static MemoryEditor mem_edit_2;
// ImGui::Begin("MyWindow")
// mem_edit_2.DrawContents(this, sizeof(*this), (size_t)this);
// ImGui::End();
//
// Changelog:
// - v0.10: initial version
// - v0.23 (2017/08/17): added to github. fixed right-arrow triggering a byte write.
// - v0.24 (2018/06/02): changed DragInt("Rows" to use a %d data format (which is desirable since imgui 1.61).
// - v0.25 (2018/07/11): fixed wording: all occurrences of "Rows" renamed to "Columns".
// - v0.26 (2018/08/02): fixed clicking on hex region
// - v0.30 (2018/08/02): added data preview for common data types
// - v0.31 (2018/10/10): added OptUpperCaseHex option to select lower/upper casing display [@samhocevar]
// - v0.32 (2018/10/10): changed signatures to use void* instead of unsigned char*
// - v0.33 (2018/10/10): added OptShowOptions option to hide all the interactive option setting.
// - v0.34 (2019/05/07): binary preview now applies endianness setting [@nicolasnoble]
// - v0.35 (2020/01/29): using ImGuiDataType available since Dear ImGui 1.69.
// - v0.36 (2020/05/05): minor tweaks, minor refactor.
// - v0.40 (2020/10/04): fix misuse of ImGuiListClipper API, broke with Dear ImGui 1.79. made cursor position appears on left-side of edit box. option popup appears on mouse release. fix MSVC warnings where _CRT_SECURE_NO_WARNINGS wasn't working in recent versions.
// - v0.41 (2020/10/05): fix when using with keyboard/gamepad navigation enabled.
// - v0.42 (2020/10/14): fix for . character in ASCII view always being greyed out.
// - v0.43 (2021/03/12): added OptFooterExtraHeight to allow for custom drawing at the bottom of the editor [@leiradel]
// - v0.44 (2021/03/12): use ImGuiInputTextFlags_AlwaysOverwrite in 1.82 + fix hardcoded width.
// - v0.50 (2021/11/12): various fixes for recent dear imgui versions (fixed misuse of clipper, relying on SetKeyboardFocusHere() handling scrolling from 1.85). added default size.
// - v0.51 (2024/02/22): fix for layout change in 1.89 when using IMGUI_DISABLE_OBSOLETE_FUNCTIONS. (#34)
// - v0.52 (2024/03/08): removed unnecessary GetKeyIndex() calls, they are a no-op since 1.87.
// - v0.53 (2024/05/27): fixed right-click popup from not appearing when using DrawContents(). warning fixes. (#35)
// - v0.54 (2024/07/29): allow ReadOnly mode to still select and preview data. (#46) [@DeltaGW2])
// - v0.55 (2024/08/19): added BgColorFn to allow setting background colors independently from highlighted selection. (#27) [@StrikerX3]
// added MouseHoveredAddr public readable field. (#47, #27) [@StrikerX3]
// fixed a data preview crash with 1.91.0 WIP. fixed contiguous highlight color when using data preview.
// *BREAKING* added UserData field passed to all optional function handlers: ReadFn, WriteFn, HighlightFn, BgColorFn. (#50) [@silverweed]
// - v0.56 (2024/11/04): fixed MouseHovered, MouseHoveredAddr not being set when hovering a byte being edited. (#54)
// - v0.57 (2025/03/26): fixed warnings. using ImGui's ImSXX/ImUXX types instead of e.g. int32_t/uint32_t. (#56)
// - v0.58 (2025/03/31): fixed extraneous footer spacing (added in 0.51) breaking vertical auto-resize. (#53)
//
// TODO:
// - This is generally old/crappy code, it should work but isn't very good.. to be rewritten some day.
// - PageUp/PageDown are not supported because we use _NoNav. This is a good test scenario for working out idioms of how to mix natural nav and our own...
// - Arrows are being sent to the InputText() about to disappear which for LeftArrow makes the text cursor appear at position 1 for one frame.
// - Using InputText() is awkward and maybe overkill here, consider implementing something custom.
