preen-os

This crate serves as the Operating System Abstraction Layer (OSAL) for the Preen project.

It is responsible for implementing the Ports defined in preen-core with platform-specific code (e.g., calling macOS-specific APIs or reading Linux configuration files). This separation ensures that the core logic remains clean and portable.

Role in Architecture

In the Hexagonal Architecture, preen-os acts as the Adapter that connects the Core to the external world (the Operating System).

• Input: Receives requests from preen-core via the FileSystemPort trait.
• Output: Executes the necessary system calls and returns the results back to the Core.

Implementation Details (Planned)

• Conditional Compilation: Uses #[cfg(target_os = "macos")] and #[cfg(target_os = "linux")] to include the correct platform-specific code.
• Dependencies: Will rely on crates like sysinfo or platform-specific FFI bindings for low-level access.

Usage

This is a library crate intended to be used by preen-core (or directly by the binaries if needed) within the main Preen workspace.
