//
// NOTE(Kalinovcic): I have translated the original implementation to C,
// and made a preprocessor define that enables people to include it without
// the implementation, just as a header.
//
// I also fixed two bugs:
//   - If COM initialization for VS2017 fails, we actually properly continue
//     searching for earlier versions in the registry.
//   - For earlier versions, the code now returns the "bin\amd64" VS directory.
//     Previously it was returning the "bin" directory, which is for x86 stuff.
//
// To include the implementation, before including microsoft_craziness.h,
// define:
//
//   #define MICROSOFT_CRAZINESS_IMPLEMENTATION
//   #include "microsoft_craziness.h"

//
// HOW TO USE THIS CODE
//
// The purpose of this file is to find the folders that contain libraries
// you may need to link against, on Windows, if you are linking with any
// compiled C or C++ code. This will be necessary for many non-C++ programming
// language environments that want to provide compatibility.
//
// We find the place where the Visual Studio libraries live (for example,
// libvcruntime.lib), where the linker and compiler executables live
// (for example, link.exe), and where the Windows SDK libraries reside
// (kernel32.lib, libucrt.lib).
//
// We all wish you didn't have to worry about so many weird dependencies,
// but we don't really have a choice about this, sadly.
//
// I don't claim that this is the absolute best way to solve this problem,
// and so far we punt on things (if you have multiple versions of Visual Studio
// installed, we return the first one, rather than the newest). But it
// will solve the basic problem for you as simply as I know how to do it,
// and because there isn't too much code here, it's easy to modify and expand.
//
//
// Here is the API you need to know about:
//

//
// Call find_visual_studio_and_windows_sdk, look at the resulting
// paths, then call free_resources on the result.
//
// Everything else in this file is implementation details that you
// don't need to care about.
//

//
// This file was about 400 lines before we started adding these comments.
// You might think that's way too much code to do something as simple
// as finding a few library and executable paths. I agree. However,
// Microsoft's own solution to this problem, called "vswhere", is a
// mere EIGHT THOUSAND LINE PROGRAM, spread across 70 files,
// that they posted to github *unironically*.
//
// I am not making this up: https://github.com/Microsoft/vswhere
//
// Several people have therefore found the need to solve this problem
// themselves. We referred to some of these other solutions when
// figuring out what to do, most prominently ziglang's version,
// by Ryan Saunderson.
//
// I hate this kind of code. The fact that we have to do this at all
// is stupid, and the actual maneuvers we need to go through
// are just painful. If programming were like this all the time,
// I would quit.
//
// Because this is such an absurd waste of time, I felt it would be
// useful to package the code in an easily-reusable way, in the
// style of the stb libraries. We haven't gone as all-out as some
// of the stb libraries do (which compile in C with no includes, often).
// For this version you need C++ and the headers at the top of the file.
//
// We return the strings as Windows wide character strings. Aesthetically
// I don't like that (I think most sane programs are UTF-8 internally),
// but apparently, not all valid Windows file paths can even be converted
// correctly to UTF-8. So have fun with that. It felt safest and simplest
// to stay with wchar_t since all of this code is fully ensconced in
// Windows crazy-land.
//
// One other shortcut I took is that this is hardcoded to return the
// folders for x64 libraries. If you want x86 or arm, you can make
// slight edits to the code below, or, if enough people want this,
// I can work it in here.
