Single-header file picker Windows library for ImGui.
# How to use
int renderFilePicker(wchar_t* userPath, bool* windowOpen, int windowFlags = 0) {
Call `int fp::renderFilePicker(wchar_t* userPath, bool* windowOpen, int windowFlags = 0);` within the render loop providing a pre-allocated C-string buffer of MAX_PATH characters in `userPath`. `windowOpen` must be initially set to `true`, and will set itself to `false` when execution is done. If succesful, your buffer will contain a valid path. You can check the file picker state each frame by parsing this function's return value. You can provide `windowFlags` to customize its appearance.
## Window states
```
- fp::ExitFlags::EXIT_CONTINUE : Window will render next frame.
- fp::ExitFlags::EXIT_SELECTED : A path has been successfully returned, window will close.
- fp::ExitFlags::EXIT_CLOSED : User has closed the window. No path is returned.
- fp::ExitFlags::EXIT_ERROR : An unexpected error has ocurred. No path is returned.
```
## Valid window flags
```
- fp::WindowFlags::FP_FULLSCREEN`: Render window in full screen, without decorations.
```
# Library dependencies
- **C++ STL**: This library uses `vector` and `w\string`.
## Build considerations
Define `DEBUG` to print relevant information to the console.
# Demo build instructions
## Build requirements
- [**GLFW v3**](https://github.com/glfw/glfw/releases): used as rendering backend. Executable in releases is compiled with version [`3.3.8`](https://github.com/glfw/glfw/releases/tag/3.3.8).
- Compiled with `clang` using [**llvm-mingw 20220906**](https://github.com/mstorsjo/llvm-mingw/releases/tag/20220906).
## How to compile
Download GLFW and pick your libraries according to your toolchain(`mingw-w64` in this example).
Then, call your compiler directly (`clang` is demonstrated here) specifying both libs needed and your paths to the necessary header and lib files:
```
clang++ demo/main.cpp -o demo/demo.exe -L C:/pathtollvmmingw/x86_64-w64-mingw32/bin -I C:\pathtollvmmingw\include -L C:/pathtoglfw/lib-mingw-w64 -I C:\pathtoglfw\include -lglfw3 -l libc++
```
If you want to statically link:
```
clang++ demo/main.cpp -o demo/si.exe -DDEBUG -L C:\capybara\libclang\x86_64-w64-mingw32\bin -L C:\capybara\libclang\x86_64-w64-mingw32\lib -I C:\capybara\libclang\include -std=c++17 -lglfw3 -l opengl32 -l gdi32 -l user32 -l kernel32 -l imm32 -static-libstdc++ --verbose
```
Add `-DDEBUG` to print filepicker's debug information, if you so desire.
# To-Dos
- Implement a file watcher to check for changes on the current directory.
- Add Linux support.
- Allow users to provide their own memory allocations as an option.
