# `mix f3.inspect`

Prints metadata for one F3 file.

    mix f3.inspect test/fixtures/small.f3
    mix f3.inspect test/fixtures/small.f3 --detail
    mix f3.inspect test/fixtures/small.f3 --json

The output is `F3.inspect/2`. It does not read row data.

`--detail` adds row groups. `--json` prints the metadata map.
`--max-metadata-bytes N` overrides the footer cap. No path, or an unknown
flag, raises `Mix.Error`. A missing file raises `Mix.Error` with the
`F3.Error` message.

# `run`

Runs the task.

`args` is the command-line list. A successful run prints the inspection
and returns `:ok`. An empty list raises `Mix.Error`.

## Examples

    iex> Mix.Tasks.F3.Inspect.run([])
    ** (Mix.Error) usage: mix f3.inspect FILE [--detail] [--json] [--max-metadata-bytes N]
