## What it is
A Rust CLI tool that compiles a regular expression into a DFA and serializes it as a FAT32 filesystem image, where directory traversal encodes state transitions. Matching a string is done by checking whether a corresponding path exists after mounting the image.

## Use cases
- turn a regex into a fat32 filesystem image
- match strings by checking if a path exists in a mounted filesystem
- explore a regex DFA as directory loops
- novelty demo of DFA serialization into fat32

## When to choose
- you want a fun, hacky way to represent a regex DFA as a filesystem
- you want to visualize or walk a DFA via directory structure
- you're experimenting with filesystems that allow directory loops

## When to avoid
- you need a practical regex engine for real applications
- you need reliable, production-grade filesystem images
- you're on a system whose FAT32 driver rejects directory loops

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: parser, serialization, file-system, cli
- domain: developer-tools, files
- platform: windows, cli, rust
- tags: regex, fat32, dfa, novelty, filesystem-image, algorithms, command-line, linux, macos
