Running `--new FILE.EXT` will:
- infer the output format form `EXT`
- use `FILE.EXT` as the output
- start with a single, empty, named directory (but allocate a bit more space)
In implementing this, I realized that introducing metadata (

ffs: the file filesystem
ffs, the file filessytem, let's you mount semi-structured data as a fileystem---a tree structure you already know how to work with!
Working with semi-structured data using command-line tools is hard. Tools like jq help a lot, but learning a new language for simple manipulations is a big ask. By mapping hard-to-parse trees into a filesystem, you can keep using the tools you know.
Example
Run ffs [file] to mount file.blah at the mountpoint file. The
final, updated version of the file will be outputted on stdout.
$ cat object.json
{ "name": "Michael Greenberg", "eyes": 2, "fingernails": 10, "human": true }
$ ffs -o object_edited.json object.json &
[1] 60182
$ tree object
object
├── eyes
├── fingernails
├── human
└── name
0 directories, 4 files
$ echo Mikey Indiana >object/name
$ echo 1 >object/nose
$ mkdir object/pockets
$ cd object/pockets/
$ echo keys >pants
$ echo pen >shirt
$ cd ..
$ cd ..
$ umount object
$
[1]+ Done ffs -o object_edited.json object.json
$ cat object_edited.json
{"eyes":2,"fingernails":10,"human":true,"name":"Mikey Indiana","nose":1,"pockets":{"pants":"keys","shirt":"pen"}}
You can specify an explicit mountpoint by running ffs -m MOUNT file;
you can specify an output file with -o OUTPUT. You can edit a file
in place by running ffs -i file---when the volume is unmounted, the
resulting output will be written back to file.
External dependencies
You need an appropriate FUSE or macFUSE along with pkg-config.
See the GitHub build workflow for examples of external dependency installation.
