# Minimalist Fuse Manager (MFM)

MFM is a Crystal-lang CLI tailored to simplify the management of encrypted vaults using multiple FUSE filesystems such as sshfs, gocryptfs, httpdirfs, and more. It provides a user-friendly interface, enabling users to smoothly mount and unmount filesystems, obtain filesystem status, and handle errors adeptly.

## Prerequisites & Dependencies

Before using MFM, ensure the following tools are installed on your system:

- **gocryptfs**: <https://github.com/rfjakob/gocryptfs>
- **sshfs**: <https://github.com/libfuse/sshfs>
- **httpdirfs**: <https://github.com/fangfufu/httpdirfs>
- **fzf**: <https://github.com/junegunn/fzf>

To build from source, you'll also require:

- **crystal-lang** : <https://crystal-lang.org/>

## Usage

### Command Line Options

```
Usage: mfm [options]

Global options:
    -c, --config FILE                Define configuration file
    -h, --help                       Showcase this help

    edit                             Adjust the configuration
```


## Configuration

The script harnesses a YAML configuration file, typically located at `~/.config/mfm.yml`, which outlines vault names and paths.

### YAML File Format

```yaml
version: "1"

global:
  mountpoint: "/home/user/mnt/{{name}}"

filesystems:
  - type: "gocryptfs"
    name: "Work - SSH Keys"
    encrypted_path: "/home/user/.ssh/keyring.work"

  - type: "sshfs"
    name: "Personal - Media Server"
    remote_user: "user"
    remote_host: "mediaserver.local"
    remote_path: "/mnt/largedisk/music"
    remote_port: 22
  
  # Incorporate more vaults as necessary
```
