shellout

A Gleam wrapper for Elixir.System.cmd/3

Usage

import gleam/iterator
import shellout

try tuple(output, status) =
  shellout.cmd("ls", ["-lah"], [StderrToStdout(True)])

output
|> iterator.from_list
|> iterator.map(with: fn(line) { io.print(line) })
|> iterator.run

status

As a dependency of your Mix project

Add shellout to mix.exs:

{:shellout, "~> 0.1"},

Tooling improvements are in the works. For now the following commands should work.

From your project’s root dir:

$ mix deps.get
$ sh -c 'cd deps/shellout/ && mix deps.get && mix compile'
$ mix compile  # or mix escript.build, etc

Test

$ mix eunit

Notice

shellout.{cmd} is intended as a short-term solution. Users should favor gleam_stdlib’s gleam/os.{cmd} (or its equivalent), once it exists.
