Version 1.65

If you were conveniently using the imgui copy of those STB headers in your project, you will have to update your include paths.
The reason for this change is to avoid conflicts for projects that may also be importing their own copy of the STB libraries. Note that imgui's copy of stb_textedit.h is modified.

 - If you get a assert, use a debugger to locate the line triggering it and read the comments around the assert.
 
 **Guidelines to report an issue or ask a question:**
-- Try to provide a Minimal, Complete and Verifiable Example ([MCVE](https://stackoverflow.com/help/mcve)) to demonstrate your problem. An ideal submission includes a small piece of code that anyone can paste in one of the examples/ application to understand and reproduce it. Narrowing your problem to its shortest and purest form is often the easiest way to understand it. Often while creating the MCVE you will end up solving the problem!
-- Try to attach screenshots to clarify the context. They often convey useful information that are omitted by the description. You can drag pictures/files here (prefer github attachments over 3rd party hosting).
-- If you are discussing an assert or a crash, please provide a debugger callstack. 
 - Please provide your imgui version number.
 - Please state if you have made substantial modifications to your copy of imgui. 
-- When discussing issues related to rendering or inputs, please state which OS you are using, and if you are using a vanilla copy of one of the back end (imgui_impl_xxx files), or a modified one, or if you built your own.
+- Try to be explicit with your expectations and what you have tried. What you have in mind or in your code is not obvious to other people.
+- If you are discussing an assert or a crash, please provide a debugger callstack. Never state "it crashes" without additional information. If you don't know how to use a debugger and retrieve a callstack, learning about it will be useful.
+- Please make sure that your compilation settings have asserts enabled. Calls to IM_ASSERT() are scattered in the code to help catch common issues. By default IM_ASSERT() calls the standard assert() function. To verify that your asserts are enabled, add the line `IM_ASSERT(false);` in your main() function. Your application should display an error message and abort. If your application report an error, it means that your asserts are disabled. Please make sure they are enabled.
+- When discussing issues related to rendering or inputs, please state the OS/back-end/renderer you are using. Please state if you are using a vanilla copy of the example back-ends (imgui_impl_XXX files), or a modified one, or if you built your own.
+- Please provide a Minimal, Complete and Verifiable Example ([MCVE](https://stackoverflow.com/help/mcve)) to demonstrate your problem.

Often while creating the MCVE you will end up solving the problem!

 _NB: those third-party bindings may be more or less maintained, more or less close to the original API (as people who create language bindings sometimes haven't used the C++ API themselves.. for the good reason that they aren't C++ users). Dear ImGui was designed with C++ in mind and some of the subtleties may be lost in translation with other languages. If your language supports it, I would suggest replicating the function overloading and default parameters used in the original, else the API may be harder to use. In doubt, please check the original C++ version first!_

 Frequently Asked Question (FAQ)
 -------------------------------
 
-<b>Where is the documentation?</b>
+**Where is the documentation?**
 
 - The documentation is at the top of imgui.cpp + effectively imgui.h. 
 - Example code is in imgui_demo.cpp and particularly the ImGui::ShowDemoWindow() function. It covers most features of ImGui so you can read the code and call the function itself to see its output. 
 - Standalone example applications using e.g. OpenGL/DirectX are provided in the examples/ folder. 
 - We obviously needs better documentation! Consider contributing or becoming a [Patron](http://www.patreon.com/imgui) to promote this effort.
 
-<b>Which version should I get?</b>
+**Which version should I get?**
 
 I occasionally tag [Releases](https://github.com/ocornut/imgui/releases) but it is generally safe and recommended to sync to master/latest. The library is fairly stable and regressions tend to be fixed fast when reported. 
 
-<b>Who uses Dear ImGui?</b>
+**Who uses Dear ImGui?**
 
 See the [Software using dear imgui page](https://github.com/ocornut/imgui/wiki/Software-using-dear-imgui) for an (incomplete) list of games/software which are publicly known to use dear imgui. Please add yours if you can!
 
-<b>Why the odd dual naming, "dear imgui" vs "ImGui"?</b>
+**Why the odd dual naming, "dear imgui" vs "ImGui"?**
 
 The library started its life and is best known as "ImGui" only due to the fact that I didn't give it a proper name when I released it. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations. It seemed confusing and unfair to hog the name. To reduce the ambiguity without affecting existing codebases, I have decided on an alternate, longer name "dear imgui" that people can use to refer to this specific library in ambiguous situations.

-<b>How do you use Dear ImGui on a platform that may not have a mouse or keyboard?</b>
+**How do you use Dear ImGui on a platform that may not have a mouse or keyboard?**
 
 You can control Dear ImGui with a gamepad, see the explanation in imgui.cpp about how to use the navigation feature (short version: map your gamepad inputs into the `io.NavInputs[]` array and set `io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad`).
 
-You can share your computer mouse seamlessy with your console/tablet/phone using [Synergy](http://synergy-project.org). This is the prefered solution for developer productivity. In particular, their [micro-synergy-client](https://github.com/symless/micro-synergy-client) repo there is _uSynergy.c_ sources for a small embeddable that you can use on any platform to connect to your host PC using Synergy 1.x. You may also use a third party solution such as [Remote ImGui](https://github.com/JordiRos/remoteimgui).

-For touch inputs, you can increase the hit box of widgets (via the _style.TouchPadding_ setting) to accommodate a little for the lack of precision of touch inputs, but it is recommended you use a mouse or gamepad to allow optimising for screen real-estate and precision.

-<b>Can you create elaborate/serious tools with Dear ImGui?</b>
+**Can you create elaborate/serious tools with Dear ImGui?**
 
 Yes. People have written game editors, data browsers, debuggers, profilers and all sort of non-trivial tools with the library. In my experience the simplicity of the API is very empowering. Your UI runs close to your live data. Make the tools always-on and everybody in the team will be inclined to create new tools (as opposed to more "offline" UI toolkits where only a fraction of your team effectively creates tools). The list of sponsors below is also an indicator that serious game teams have been using the library.
 
 Dear ImGui is very programmer centric and the immediate-mode GUI paradigm might requires you to readjust some habits before you can realize its full potential. Dear ImGui is about making things that are simple, efficient and powerful.
 
-<b>Can you reskin the look of Dear ImGui?</b>
+**Can you reskin the look of Dear ImGui?**
 
-You can alter the look of the interface to some degree: changing colors, sizes, padding, rounding, fonts. However, as Dear ImGui is designed and optimised to create debug tools, the amount of skinning you can apply is limited. There is only so much you can stray away from the default look and feel of the interface. Below is a screenshot from [LumixEngine](https://github.com/nem0/LumixEngine) with custom colors + a docking/tabs extension (both of which you can find in the Issues section and will eventually be merged):

-<b>Why using C++ (as opposed to C)?</b>
+**Why using C++ (as opposed to C)?**
 
 Dear ImGui takes advantage of a few C++ languages features for convenience but nothing anywhere Boost-insanity/quagmire. Dear ImGui does NOT require C++11 so it can be used with most old C++ compilers. Dear ImGui doesn't use any C++ header file. Language-wise, function overloading and default parameters are used to make the API easier to use and code more terse. Doing so I believe the API is sitting on a sweet spot and giving up on those features would make the API more cumbersome. Other features such as namespace, constructors and templates (in the case of the ImVector<> class) are also relied on as a convenience.
 
-There is an reasonably maintained [c-api for ImGui](https://github.com/Extrawurst/cimgui) by Stephan Dilly designed for binding in other languages. I would suggest using your target language functionalities to try replicating the function overloading and default parameters used in C++ else the API may be harder to use. Also see [Links](https://github.com/ocornut/imgui/wiki/Links) for third-party bindings to other languages.

+Dear ImGui is highly portable and only requires a few things to run and render:
 
-
-TL;DR; 
- - Newcomers, read 'PROGRAMMER GUIDE' in imgui.cpp for notes on how to setup ImGui in your codebase.
- - If you are using of the backend provided here, so you can copy the imgui_impl_xxx.cpp/h files
-   to your project and use them unmodified.
- - To LEARN how to setup imgui, you may refer to 'opengl2_example' because is the simplest one to read.
-   However, do NOT USE the 'opengl2_example' if your code is using any modern GL3+ calls.
-   Mixing old fixed-pipeline OpenGL2 and modern OpenGL3+ is going to make everything more complicated.
-   Read comments below for details. If you are not sure, in doubt, use 'opengl3_example'.
- - If you have your own engine, you probably want to read a few of the examples first then adapt it to
-   your engine. Please note that if your engine is based on OpenGL/DirectX you can perfectly use the
-   existing rendering backends, don't feel forced to rewrite them with your own engine API, or you can
-   do that later when you already got things to work.
-
-Dear ImGui is highly portable and only requires a few things to run and render.
  - Providing mouse/keyboard inputs
- - Load the font atlas texture into graphics memory
+ - Uploading the font atlas texture into graphics memory
  - Providing a render function to render indexed textured triangles
  - Optional: clipboard support, mouse cursor supports, Windows IME support, etc.
-So this is essentially what those examples are doing + the obligatory cruft for portability.
 
-Unfortunately in 2018 it is still tedious to create and maintain portable build files using external 
-libraries (the kind we're using here to create a window and render 3D triangles) without relying on 
-third party software. For most examples here I choose to provide:
- - Makefiles for Linux/OSX
- - Batch files for Visual Studio 2008+
- - A .sln project file for Visual Studio 2010+ 
-Please let me know if they don't work with your setup!
-You can probably just import the imgui_impl_xxx.cpp/.h files into your own codebase or compile those
-directly with a command-line compiler.
+This is essentially what the example bindings in this folder are providing + obligatory portability cruft.
 
-Dear ImGui has zero to one frame of lag for most behaviors, at 60 FPS your experience should be pleasant.
-Consider that OS mouse cursors are typically drawn through a specific hardware accelerated route and may 
-feel smoother than other GPU rendered contents. You may experiment with the io.MouseDrawCursor flag to
-request ImGui to draw a mouse cursor itself, to visualize the lag between a hardware cursor and a software
-cursor. It might be beneficial to the user experience to switch to a software rendered cursor when an
-interactive drag is in progress. 
-Also note that some setup or GPU drivers may be causing extra lag (possibly by enforcing triple buffering),
-leaving you with little option but sadness (Intel GPU drivers were reported as such).
+It is important to understand the difference between the core Dear ImGui library (files in the root folder)
+and examples bindings which we are describing here (examples/ folder).
+You should be able to write bindings for pretty much any platform and any 3D graphics API. With some extra
+effort you can even perform the rendering remotely, on a different machine than the one running the logic.
+
+This folder contains two things:
+
+ - Example bindings for popular platforms/graphics API, which you can use as is or adapt for your own use.
+   They are the imgui_impl_XXXX files found in the examples/ folder.
+
+ - Example applications (standalone, ready-to-build) using the aforementioned bindings.
+   They are the in the XXXX_example/ sub-folders.
+
+You can find binaries of some of those example applications at: 
+  http://www.miracleworld.net/imgui/binaries
 
 
-opengl2_example/
-    **DO NOT USE THIS CODE IF YOUR CODE/ENGINE IS USING MODERN OPENGL (SHADERS, VBO, VAO, etc.)**
-    **Prefer using the code in the opengl3_example/ folder**
-    GLFW + OpenGL example (legacy, fixed pipeline).
-    This code is mostly provided as a reference to learn how ImGui integration works, because it is shorter.
-    If your code is using GL3+ context or any semi modern OpenGL calls, using this renderer is likely to
-    make things more complicated, will require your code to several OpenGL attributes to their initial state,
-    and might confuse your GPU driver. 
+---------------------------------------
+ MISC COMMENTS AND SUGGESTIONS
+---------------------------------------
 
-opengl3_example/
-    GLFW + OpenGL example (programmable pipeline, binding modern functions with GL3W).
-    This uses more modern OpenGL calls and custom shaders. 
-    Prefer using that if you are using modern OpenGL in your application (anything with shaders).
+ - Please read 'PROGRAMMER GUIDE' in imgui.cpp for notes on how to setup Dear ImGui in your codebase.
+   Please read the comments and instruction at the top of each file.
+   
+ - If you are using of the backend provided here, so you can copy the imgui_impl_xxx.cpp/h files
+   to your project and use them unmodified. Each imgui_impl_xxxx.cpp comes with its own individual
+   ChangeLog at the top of the .cpp files, so if you want to update them later it will be easier to
+   catch up with what changed.
 
-directx9_example/
+ - Dear ImGui has 0 to 1 frame of lag for most behaviors, at 60 FPS your experience should be pleasant.
+   However, consider that OS mouse cursors are typically drawn through a specific hardware accelerated path
+   and will feel smoother than common GPU rendered contents (including Dear ImGui windows). 
+   You may experiment with the io.MouseDrawCursor flag to request ImGui to draw a mouse cursor itself, 
+   to visualize the lag between a hardware cursor and a software cursor. However, rendering a mouse cursor
+   at 60 FPS will feel slow. It might be beneficial to the user experience to switch to a software rendered
+   cursor only when an interactive drag is in progress. 
+   Note that some setup or GPU drivers are likely to be causing extra lag depending on their settings.
+   If you feel that dragging windows feels laggy and you are not sure who to blame: try to build an 
+   application drawing a shape directly under the mouse cursor.
+
+
+---------------------------------------
+ EXAMPLE BINDINGS
+---------------------------------------
+
+Most the example bindings are split in 2 parts:
+
+ - The "Platform" bindings, in charge of: mouse/keyboard/gamepad inputs, cursor shape, timing, windowing.
+   Examples: Windows (imgui_impl_win32.cpp), GLFW (imgui_impl_glfw.cpp), SDL2 (imgui_impl_sdl.cpp)
+
+ - The "Renderer" bindings, in charge of: creating the main font texture, rendering imgui draw data.
+   Examples: DirectX11 (imgui_impl_dx11.cpp), GL3 (imgui_impl_opengl3.cpp), Vulkan (imgui_impl_vulkan.cpp)
+
+ - The example _applications_ usually combine 1 platform + 1 renderer binding to create a working program.
+   Examples: the example_win32_directx11/ application combines imgui_impl_win32.cpp + imgui_impl_dx11.cpp.
+
+ - Some bindings for higher level frameworks carry both "Platform" and "Renderer" parts in one file.
+   This is the case for Allegro 5 (imgui_impl_allegro5.cpp), Marmalade (imgui_impl_marmalade5.cpp).
+
+ - If you use your own engine, you may decide to use some of existing bindings and/or rewrite some using 
+   your own API. As a recommendation, if you are new to Dear ImGui, try using the existing binding as-is
+   first, before moving on to rewrite some of the code. Although it is tempting to rewrite both of the 
+   imgui_impl_xxxx files to fit under your coding style, consider that it is not necessary!
+   In fact, if you are new to Dear ImGui, rewriting them will almost always be harder.
+
+   Example: your engine is built over Windows + DirectX11 but you have your own high-level rendering 
+   system layered over DirectX11.
+     Suggestion: step 1: try using imgui_impl_win32.cpp + imgui_impl_dx11.cpp first. 
+     Once this work, _if_ you want you can replace the imgui_impl_dx11.cpp code with a custom renderer 
+     using your own functions, etc. 
+     Please consider using the bindings to the lower-level platform/graphics API as-is.
+
+   Example: your engine is multi-platform (consoles, phones, etc.), you have high-level systems everywhere.
+     Suggestion: step 1: try using a non-portable binding first (e.g. win32 + underlying graphics API)!
+     This is counter-intuitive, but this will get you running faster! Once you better understand how imgui
+     works and is bound, you can rewrite the code using your own systems.
+
+ - Road-map: Dear ImGui 1.70 (WIP currently in the "viewport" branch) will allows imgui windows to be 
+   seamlessly detached from the main application window. This is achieved using an extra layer to the 
+   platform and renderer bindings, which allows imgui to communicate platform-specific requests.
+   If you decide to use unmodified imgui_impl_xxxx.cpp files, you will automatically benefit from 
+   improvements and fixes related to viewports and platform windows without extra work on your side.

-# iOS / OSX example
-
-## Introduction
-
-This example is the default XCode "OpenGL" example code, modified to support ImGui and [Synergy](http://synergy-project.org/) to share mouse/keyboard on an iOS device.
-
-It is a rather complex and messy example because of all of the faff required to get an XCode/iOS application running. Refer to the regular OpenGL examples if you want to learn about integrating ImGui. **The opengl3_example/ should also work on OS X and is much simpler.** This is an integration for iOS with Synergy.
-
-Synergy (remote keyboard/mouse) is not required, but it's pretty hard to use ImGui without it. Synergy includes a "uSynergy" library that allows embedding a synergy client, this is what is used here. ImGui supports "TouchPadding", and this is enabled when Synergy is not active.
-
-## How to Use on iOS
-
-* In Synergy, go to Preferences, and uncheck "Use SSL encryption"
-* Run the example app.
-* Tap the "servername" button in the corner
-* Enter the name or the IP of your synergy host
-* If you had previously connected to a server, you may need to kill and re-start the app.
-
-## How to Build on OSX
-
-* Make sure you have install `brew`, if not, please refer to [Homebrew Website](http://brew.sh)
-* Run the command: `brew install glfw3`
-* Double click `imguiex.xcodeproj` and select `imguiex-osx` scheme
-* Click `Run` button
-
-## Notes and TODOs
-
-Things that would be nice but I didn't get around to doing:
-
-* iOS software keyboard not supported for text inputs
-* iOS hardware (bluetooth) keyboards not supported
-* Graceful disconnect/reconnect from uSynergy.
-* Copy/Paste not well-supported
-
-## C++ on iOS / OSX
-
-ImGui is a c++ library. If you want to include it directly, rename your Obj-C file to have the ".mm" extension. 
-
-Alternatively, you can wrap your debug code in a C interface, this is what I am demonstrating here with the "debug_hud.h" interface. Either approach works, use whatever you prefer.
-
-In my case, most of my game code is already in C++ so it's not really an issue and I can use ImGui directly.

-// ImGui Win32 + DirectX9 binding
-
-// Implemented features:
-//  [X] User texture binding. Use 'LPDIRECT3DTEXTURE9' as ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
-
-// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
-// If you use this binding you'll need to call 4 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXXX_NewFrame(), ImGui::Render() and ImGui_ImplXXXX_Shutdown().

-
-// CHANGELOG 
-// (minor and older changes stripped away, please see git history for details)
-//  2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors and ImGuiBackendFlags_HasSetMousePos flags + honor ImGuiConfigFlags_NoMouseCursorChange flag.
-//  2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value and WM_SETCURSOR message handling).
-//  2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX9_RenderDrawData() in the .h file so you can call it yourself.
-//  2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
-//  2018-02-06: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavEnableSetMousePos is set).
-//  2018-02-06: Inputs: Added mapping for ImGuiKey_Space.

+# Configuration
+
+Dear ImGui outputs 16-bit vertex indices by default. 
+Allegro doesn't support them natively, so we have two solutions: convert the indices manually in imgui_impl_allegro5.cpp, or compile imgui with 32-bit indices.
+You can either modify imconfig.h that comes with Dear ImGui (easier), or set a C++ preprocessor option IMGUI_USER_CONFIG to find to a filename.
+We are providing `imconfig_allegro5.h` that enables 32-bit indices.
+Note that the back-end supports _BOTH_ 16-bit and 32-bit indices, but 32-bit indices will be slightly faster as they won't require a manual conversion.
+
+# How to Build
+
+- On Ubuntu 14.04+
+
+```bash
+g++ -DIMGUI_USER_CONFIG=\"examples/example_allegro5/imconfig_allegro5.h\" -I .. -I ../.. main.cpp ..\imgui_impl_allegro5.cpp ../../imgui*.cpp -lallegro -lallegro_primitives -o allegro5_example
+```
+
+- On Windows with Visual Studio's CLI
+
+```
+set ALLEGRODIR=path_to_your_allegro5_folder
+cl /Zi /MD /I %ALLEGRODIR%\include /DIMGUI_USER_CONFIG=\"examples/example_allegro5/imconfig_allegro5.h\" /I .. /I ..\.. main.cpp ..\imgui_impl_allegro5.cpp ..\..\imgui*.cpp /link /LIBPATH:%ALLEGRODIR%\lib allegro-5.0.10-monolith-md.lib user32.lib

+# iOS / OSX Metal example
+
+## Introduction
+
+This example shows how to integrate Dear ImGui with Metal. It is based on the "cross-platform" game template provided with Xcode as of Xcode 9.
+
+(NB: you may still want to use GLFW or SDL which will also support Windows, Linux along with OSX.)
