Standard Output and Error are mixed

[guidra-rev]

I would like to redirect standard output and standard error to the console, in the same order as when I call the program manually in the console.

This example provided in the ReadMe.md, will mix output and error, so I get half a sentence from output, then half a sentence from error. I don't know who would ever need that.

await using var stdOut = Console.OpenStandardOutput();
await using var stdErr = Console.OpenStandardError();

var cmd = Cli.Wrap("foo") | (stdOut, stdErr);
await cmd.ExecuteAsync();

How can I get the same order as when I call manually ?

I tried calling synchronously instead, but still same issue

using var stdOut = Console.OpenStandardOutput();
using var stdErr = Console.OpenStandardError();

var cmd = Cli.Wrap("foo") | (stdOut, stdErr);
cmd.ExecuteAsync().GetAwaiter().GetResult();

As a workaround I use buffered execution, but this results in unnecessary copying, and I only see the output once it finished running

var result = Cli.Wrap("foo")
  .ExecuteBufferedAsync()
  .GetAwaiter().GetResult();

Console.Write(result.StandardOutput);
Console.Write(result.StandardError);

The example in the readme works with raw streams, so yeah race conditions are possible.
Try this instead:

Cli.Wrap("foo") | (Console.WriteLine, Console.Error.WriteLine);

This will at least guarantee that the lines come in one piece

Thank you, exactly what I needed
