A Gleam library for cross-platform shell operations.

<br>

## Usage

### Example

• In `my_project/src/my_project.gleam`

```gleam
import gleam/io
import gleam/map
import shellout.{Lookups}

pub const lookups: Lookups = [
  #(
    ["color", "background"],
    [
      #("buttercup", ["252", "226", "174"]),
      #("mint", ["182", "255", "234"]),
      #("pink", ["255", "175", "243"]),
    ],
  ),
]

pub fn main() {
  let result =
    shellout.arguments()
    |> shellout.command(run: "ls", in: ".", opt: [])

  case result {
    Ok(output) -> {
      io.print(output)
      0
    }
    Error(#(status, message)) -> {
      message
      |> shellout.style(
        with: shellout.display(["bold", "italic"])
        |> map.merge(shellout.color(["pink"]))
        |> map.merge(shellout.background(["brightblack"])),
        custom: lookups,
      )
      |> io.print
      status
    }
  }
  |> shellout.exit
}
```

> cd my_project
> gleam run -- -lah
# ..
