# Minimalist Fuse Manager (MFM)

MFM is a Crystal-lang CLI designed to streamline the management of various FUSE filesystems, such as sshfs, gocryptfs, httpdirfs, and more. Through its user-friendly interface, users can effortlessly mount and unmount filesystems, get real-time filesystem status, and handle errors proficiently.

- **fzf**: <https://github.com/junegunn/fzf>
- libpcre3
- libevent-2.1

For Debian/Ubuntu you can use the following command:

```shell-session
$ sudo apt-get update && sudo apt-get install libpcre3 libevent-2.1-7 fzf gocryptfs httpdirfs sshfs
```

detail the filesystem names, types, and respective configurations.

### YAML File Format

```yaml
---
version: "1"

global:
  mountpoint: "{{env.HOME}}/mnt"

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

  - type: "sshfs"
    name: "Personal - Media Server"
    remote_user: "{{env.USER}}"
    remote_host: "mediaserver.local"
    remote_path: "/mnt/largedisk/music"
    remote_port: 22

  - type: httpdirfs
