// 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/branch with your modifications to imconfig.h)
// B) or add configuration directives in your own file and compile with #define IMGUI_USER_CONFIG "myfilename.h"
// If you do so 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.
//-----------------------------------------------------------------------------
#pragma once

//#define IM_ASSERT(_EXPR) ((void)(_EXPR)) // Disable asserts
//---- Define attributes of all API symbols declarations, e.g. for DLL under Windows

//#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 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().
//---- 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)

// dear imgui: Platform Binding for GLFW
// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan..)

// (Requires: GLFW 3.1+)
// Implemented features:
// [X] Platform: Clipboard support.
// [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange' (note: the resizing cursors requires GLFW 3.4+).
// [X] Platform: Keyboard arrays indexed using GLFW_KEY_* codes, e.g. ImGui::IsKeyPressed(GLFW_KEY_SPACE).
// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
// If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.
// https://github.com/ocornut/imgui
// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2020-01-17: Inputs: Disable error callback while assigning mouse cursors because some X11 setup don't have them and it generates errors.
// 2019-12-05: Inputs: Added support for new mouse cursors added in GLFW 3.4+ (resizing cursors, not allowed cursor).
// 2019-10-18: Misc: Previously installed user callbacks are now restored on shutdown.
// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
// 2019-05-11: Inputs: Don't filter value from character callback before calling AddInputCharacter().
// 2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
// 2018-11-07: Inputs: When installing our GLFW callbacks, we save user's previously installed ones - if any - and chain call them.
// 2018-08-01: Inputs: Workaround for Emscripten which doesn't seem to handle focus related calls.
// 2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
// 2018-06-08: Misc: Extracted imgui_impl_glfw.cpp/.h away from the old combined GLFW+OpenGL/Vulkan examples.
// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value, passed to glfwSetCursor()).
// 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: Added mapping for ImGuiKey_Space.
// 2018-01-25: Inputs: Added gamepad support if ImGuiConfigFlags_NavEnableGamepad is set.
// 2018-01-25: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
// 2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
// 2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.

// dear imgui: Renderer 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 Binding (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: Desktop GL only: Support for large meshes (64k+ vertices) with 16-bit indices.
// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
// If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.
// https://github.com/ocornut/imgui
// About Desktop OpenGL function loaders:
// Modern Desktop OpenGL doesn't have a standard portable header file to load OpenGL function pointers.
// Helper libraries are often used for this purpose! Here we are supporting a few common ones (gl3w, glew, glad).
// You may use another loader/header of your choice (glext, glLoadGen, etc.), or chose to manually implement your own.
// About GLSL version:
// The 'glsl_version' initialization parameter should be NULL (default) or a "#version XXX" string.
// On computer platform the GLSL version default to "#version 130". On OpenGL ES 3 platform it defaults to "#version 300 es"
// Only override if your GL version doesn't handle this GLSL version. See GLSL version table at the top of imgui_impl_opengl3.cpp.

// Those changes would need to be pushed into nothings/stb:
// - Added STBRP__CDECL
// Grep for [DEAR IMGUI] to find the changes.
// stb_rect_pack.h - v1.00 - public domain - rectangle packing
// Sean Barrett 2014
//
// Useful for e.g. packing rectangular textures into an atlas.
// Does not do rotation.
//
// 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.

# CSE2
CSE2 is a decompilation of Cave Story.
This branch migrates the engine away from WinAPI and DirectX, and addresses
numerous portability issues, allowing it to run on other platforms.
Supported platforms include...
* Windows
* Linux
* macOS
* Wii U
* 3DS
* RISC OS

And... that's it! It's not often that a game this decompilable comes along, so
I'm glad that Cave Story was one of them. [Patching a dusty old executable from 2005 sucks](https://github.com/Clownacy/Cave-Story-Mod-Loader/blob/master/src/mods/graphics_enhancement/widescreen/patch_camera.c).
## Dependencies
* SDL2 (if `BACKEND_AUDIO` or `BACKEND_PLATFORM` are set to `SDL2`)
* SDL (if `BACKEND_AUDIO` or `BACKEND_PLATFORM` are set to `SDL1`)
* GLFW3 (if `BACKEND_PLATFORM` is set to `GLFW3`)
* FreeType (if `FREETYPE_FONTS` is enabled)
If these are not found, they will be built locally (with the exception of SDL).
In addition, `pkg-config` is required for builds that require static-linkage.
A list of dependencies for specific platforms can be found [on the wiki](https://github.com/Clownacy/CSE2/wiki/Dependency-lists).
## Building
This project uses CMake, allowing it to be built with a range of compilers.
### Visual Studio .NET 2003
(A beginner-friendly guide can be found in [VISUAL_STUDIO_2019_GUIDE.md](VISUAL_STUDIO_2019_GUIDE.md))
Project files for Visual Studio .NET 2003 are available, and can be found in the
'vs2003' folder.
As proven by the original `Doukutsu.exe`'s [Rich Header](http://bytepointer.com/articles/the_microsoft_rich_header.htm),
Pixel used Visual Studio .NET 2003 to compile Cave Story. This means these
project files allow us to check the accuracy of the decompilation by comparing
the generated assembly code to that of the original executable. The tool for
this can be found in the 'devilution' folder.
### CMake (Visual Studio & MinGW-w64)
Switch to the terminal (Visual Studio users should open the [Developer Command Prompt](https://docs.microsoft.com/en-us/dotnet/framework/tools/developer-command-prompt-for-vs))
and `cd` into this folder. After that, generate the files for your build system

### Building for the Wii U
### Makefile (MinGW-w64) \[deprecated - use CMake instead\]
To target the Wii U, you'll need devkitPro, devkitPPC, and WUT.
Run 'make' in this folder, preferably with some of the following settings:
First, add the devkitPPC tools directory to your PATH (because WUT's CMake
support is broken, as of writing):
Name | Function
--------|--------
`JAPANESE=1` | Enable the Japanese-language build (instead of the unofficial Aeon Genesis English translation)
`FIX_BUGS=1` | Fix various bugs in the game
`FIX_MAJOR_BUGS=1` | Fix bugs that invoke undefined behaviour or cause memory leaks
`DEBUG_SAVE=1` | Re-enable [the dummied-out 'Debug Save' option](https://tcrf.net/Cave_Story#Debug_Save), and the ability to drag-and-drop save files onto the window
`RELEASE=1` | Compile a release build (optimised, stripped, etc.)
`STATIC=1` | Produce a statically-linked executable (so you don't need to bundle DLL files)
```
PATH=$PATH:$DEVKITPPC/bin
```
You can pass your own compiler flags by defining `CXXFLAGS`.
Then, generate the build files with this command:
```
cmake -B buildwiiu -DCMAKE_BUILD_TYPE=Release -DFORCE_LOCAL_LIBS=ON -DBACKEND_PLATFORM=WiiU -DBACKEND_RENDERER=WiiU -DBACKEND_AUDIO=WiiU-Software -DDOCONFIG=OFF -DCMAKE_TOOLCHAIN_FILE=$DEVKITPRO/wut/share/wut.toolchain.cmake
```
Finally, build the game with this command:
```
cmake --build buildwiiu
```
This will build a binary, but you still need to convert it to an `.rpx` file
that can be ran on your Wii U.
First, we need to strip the binary:
```
powerpc-eabi-strip -g game_english/CSE2
```
Then, we convert it to an `.rpx`:
```
elf2rpl game_english/CSE2 game_english/CSE2.rpx
```
`game_english/CSE2.rpx` is now ready to be ran on your Wii U. This port expects
the data folder to be in a folder called `CSE2-portable-en`/`CSE2-portable-jp`
on the root of your SD card.
### Building for the 3DS
To target the 3DS, you'll need devkitPro, devkitARM, Citro2D, Citro3D, libctru,
and bannertool, along with the `3dstools` and `devkitpro-pkgbuild-helpers`
packages.
Open a terminal, and `cd` into the CSE2 directory. Then execute this command:
```
cmake -B build3ds -DCMAKE_BUILD_TYPE=Release -DFORCE_LOCAL_LIBS=ON -DBACKEND_PLATFORM=3DS -DBACKEND_RENDERER=3DS -DBACKEND_AUDIO=3DS-Hardware -DDOCONFIG=OFF -DFREETYPE_FONTS=ON -DCMAKE_TOOLCHAIN_FILE=$DEVKITPRO/3ds.cmake
```
(Note that `FREETYPE_FONTS` is enabled. If you're creating a Japanese build,
it's best to disable this, as the FreeType font is unreadable at 320x240).
This will create the build files. To build CSE2, run:
```
cmake --build build3ds
```
This will create an elf file. Before we can create a `.3dsx` file from it, we
need to make an `.smdh` file:
```
bannertool makesmdh -i $DEVKITPRO/libctru/default_icon.png -s "CSE2" -l "Port of Cave Story" -p "Clownacy" -o build3ds/smdh.smdh
```
We can finally generate a `.3dsx` file:
```
3dsxtool game_english/CSE2 game_english/CSE2.3dsx --romfs=game_english/data --smdh=build3ds/smdh.smdh
```
Once built, the executable can be found in the `game_english`/`game_japanese`
folder, depending on the selected language.

So you want to compile CSE2?
Well, to start, you'll need Visual Studio. I know a lot of people
recommend MSYS2 instead, and while it is a lot more lightweight, it's
also way more complex, and outright broken in some places, which will
make compiling an absolute nightmare (I'm looking at you, Brotli).
So, we'll be using Visual Studio Community 2019. Don't worry - it's
free. You can download it here:
https://visualstudio.microsoft.com/
Once it's downloaded, run `vs_Community.exe`. Follow the installer until
you reach this menu:
![Screenshot](images/vs2019guide1.png)
Here, you'll want to select the 'Desktop development with C++' workload,
and then click 'Install'. Once it's done installing, you'll be prompted
to restart your computer.
Next, download a copy of CSE2's source code if you haven't already and
extract it somewhere. You can find a copy of CSE2 Portable's code here:
https://github.com/Clownacy/CSE2/archive/portable.zip
You are now ready to compile CSE2. To begin, open Visual Studio 2019. If
it prompts you to open a project, select 'Continue without code' to skip
past it and enter the main IDE. It should look something like this:
![Screenshot](images/vs2019guide2.png)
From here, select `File/Open/CMake`, and then navigate to where you
extracted the CSE2 source code, and open the `CMakeLists.txt` file.
After this, Visual Studio will spend a few minutes configuring itself.
You can see all of this in the little text console at the bottom of the
window. Eventually, it will conclude, and hopefully not report any
errors. The window should now look something like this:
![Screenshot](images/vs2019guide3.png)
You are now able to produce 64-bit Debug builds of CSE2. To do so,
simply select `Build/Build All`. Like before, Visual Studio will spend
the next few minutes performing tasks, and reporting back in the text
console. It should eventually generate `CSE2_debug.exe` and
`DoConfig_debug.exe`, which you can find in CSE2's `game_english`
folder.
However, you probably want to be compiling Release builds, not Debug
builds. To do so, select the 'Open the CMake Settings Editor' option. It
will take you to this menu:
![Screenshot](images/vs2019guide4.png)
From here, change the 'Configuration type' option to 'Release'. You can
now rebuild CSE2, and the files `CSE2.exe` and `DoConfig.exe` will be
generated in the `game_english` folder.
And... that's it. If you want, you can edit CSE2's code by expanding the
`src` folder on the right, and selecting one of the various `.cpp`
files.

The PostScript Type 1 implementation of the AMSFonts produced by and
previously distributed by Blue Sky Research and Y&Y, Inc. are now freely
available for general use. This has been accomplished through the
cooperation
of a consortium of scientific publishers with Blue Sky Research and Y&Y.
Members of this consortium include:
Elsevier Science IBM Corporation Society for Industrial and Applied
Mathematics (SIAM) Springer-Verlag American Mathematical Society (AMS)
In order to assure the authenticity of these fonts, copyright will be
held by
the American Mathematical Society. This is not meant to restrict in any way
the legitimate use of the fonts, such as (but not limited to) electronic
distribution of documents containing these fonts, inclusion of these fonts
into other public domain or commercial font collections or computer
applications, use of the outline data to create derivative fonts and/or
faces, etc. However, the AMS does require that the AMS copyright notice be
removed from any derivative versions of the fonts which have been altered in
any way. In addition, to ensure the fidelity of TeX documents using Computer
Modern fonts, Professor Donald Knuth, creator of the Computer Modern faces,
has requested that any alterations which yield different font metrics be
given a different name.

Article 3 (Restriction)
The license granted in the preceding Article shall be subject to the following restrictions:
1.If a Derived Program is Redistributed pursuant to Paragraph 4 and 7 of the preceding Article, the following conditions must be met :
　(1)The following must be also Redistributed together with the Derived Program, or be made available online or by means of mailing mechanisms in exchange for a cost which does not exceed the total costs of postage, storage medium and handling fees:
　　(a)a copy of the Derived Program; and
　　(b)any additional file created by the font developing program in the course of creating the Derived Program that can be used for further modification of the Derived Program, if any.
　(2)It is required to also Redistribute means to enable recipients of the Derived Program to replace the Derived Program with the Licensed Program first released under this License (the “Original Program”). Such means may be to provide a difference file from the Original Program, or instructions setting out a method to replace the Derived Program with the Original Program.
　(3)The Recipient must license the Derived Program under the terms and conditions of this Agreement.
　(4)No one may use or include the name of the Licensed Program as a program name, font name or file name of the Derived Program.
　(5)Any material to be made available online or by means of mailing a medium to satisfy the requirements of this paragraph may be provided, verbatim, by any party wishing to do so.
2.If the Recipient Redistributes the Licensed Program pursuant to Paragraph 6 of the preceding Article, the Recipient shall meet all of the following conditions:
　(1)The Recipient may not change the name of the Licensed Program.
　(2)The Recipient may not alter or otherwise modify the Licensed Program.
　(3)The Recipient must attach a copy of this Agreement to the Licensed Program.

None of us are lawyers, but to my understanding...
Being a decompilation, much of CSE2's code belongs to Daisuke "Pixel" Amaya.
There was no licence supplied with the original freeware release, so presumably
this code defaults to 'All Rights Reserved'.
...I dunno - how many of *you* are fluent in international copyright law?
