wtf is bbfs?

BBFS, or the "Big Brother File System," is a tool that watches everything that happens in a folder on your computer. It sits between you and your files, acting as a middleman that records every action, then passes that action along to the real folder underneath. The name is a nod to the idea that it is always watching. Here is how it works at a high level. When you open, read, or save a file, you normally interact directly with your computer's storage. This tool creates a fake or "virtual" folder that looks and behaves exactly like a normal one. When you interact with this virtual folder, it notes exactly what you are trying to do, and then quietly performs that exact same action on the real, hidden folder behind the scenes. You see your files as usual, but the system gets a chance to observe the traffic flowing through it. This kind of tool is primarily useful for developers who want to understand or debug how a program interacts with files. For example, if you have an app that keeps crashing when it tries to save a document, a developer could route that app's activity through this watching folder. Instead of guessing what went wrong, the developer gets a clear log of exactly which files the app touched and what it tried to do with them. What is notable about this project is how it was built. It is written in Haskell, a programming language known for being mathematically strict and reliable. The creator wrote it specifically to test and explore how well Haskell can connect to the underlying file-watching technology. Because the ecosystem for this specific task in Haskell is still maturing, the project is as much an experiment in programming infrastructure as it is a practical utility.
