// Mini memory editor for Dear ImGui (to embed in your game/tools)
// Animated GIF: https://twitter.com/ocornut/status/894242704317530112
// Get latest version at http://www.github.com/ocornut/imgui_club
//
// 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 caling this.
//
// Usage:
// static MemoryEditor mem_edit_1; // store your state somewhere
// mem_edit_1.DrawWindow("Memory Editor", mem_block, mem_block_size, 0x0000); // create a window and draw memory editor (if you already have a window, use DrawContents())
//
// Usage:
// 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
// - v0.11: always refresh active text input with the latest byte from source memory if it's not being edited.
// - v0.12: added this.OptMidRowsCount to allow extra spacing every XX rows.
// - v0.13: added optional ReadFn/WriteFn handlers to access memory via a function. various warning fixes for 64-bits.
// - v0.14: added GotoAddr member, added GotoAddrAndHighlight() and highlighting. fixed minor scrollbar glitch when resizing.
// - v0.15: added maximum window width. minor optimization.
// - v0.16: added OptGreyOutZeroes option. various sizing fixes when resizing using the "Rows" drag.
// - v0.17: added HighlightFn handler for optional non-contiguous highlighting.
// - v0.18: fixes for displaying 64-bits addresses, fixed mouse click gaps introduced in recent changes, cursor tracking scrolling fixes.
// - v0.19: fixed auto-focus of next byte leaving WantCaptureKeyboard=false for one frame. we now capture the keyboard during that transition.
// - v0.20: added options menu. added this.OptShowAscii checkbox. added optional HexII display. split Draw() in DrawWindow()/DrawContents(). fixing glyph width. refactoring/cleaning code.
// - v0.21: fixes for using DrawContents() in our own window. fixed HexII to actually be useful and not on the wrong side.
// - v0.22: clicking Ascii view select the byte in the Hex view. Ascii view highlight selection.
// - v0.23: fixed right-arrow triggering a byte write
//
// Todo/Bugs:
// - Arrows are being sent to the InputText() about to disappear which for LeftArrow makes the text cursor appear at position 1 for one frame.
// #pragma once
// #include <stdio.h> // sprintf, scanf
