# bp3d-os

Operating system tools for BlockProject 3D.

This crate provides various platform specific tools to use by most BlockProject 3D software.

## Features

- **assets** provides access to files bundled within the application (eg: AppImage for Linux and Application bundles 
  for Apple systems).
- **dirs** provides access to various system directories to place application data, logs, config, etc.
- **fs** provides a few utilities to extend the Rust standard library around the platform file system such as managing
  hidden files or getting the absolute path of a file or directory.
- **open** provides utilities to open URLs and files using the default registered application.

## Supported platforms

Currently, the following platforms are supported:
- macOS.
- macOS (with App sandbox).
- iOS.
- Linux.
- Windows.
- Other BSD like systems.

Support for Android is currently not planned due to drastic restrictions on file sizes and largely increased complexity
of interacting with the platform (No native C API, everything goes through JVM with some custom main function).
